Description

The present invention relates to an opening and closing control system.

Conventionally, systems have been proposed for controlling the opening and closing movement of an opening/closing body of an automatic door device installed in an opening in the wall of a building. In such a system, for example, a system applied to an automatic door device whose initial state (so-called standby state) is the door fully closed method or the door fully open method has been proposed, in which a single control unit is used to control the opening and closing of the door based on the operation of various switches and the detection results of sensors. Furthermore, the control contents of the control unit in the fully closed door method and the control contents of the control unit in the fully open door method are set to be different from each other.

JP 2005-163408 A

As described above, in the conventional system, the control contents of the control unit in the fully closed door mode and the control contents of the control unit in the fully open door mode are set differently, so it is difficult to use a general-purpose control device as the control unit as is, and it is necessary to create a control program for the system according to the standby state, so there is room for improvement in terms of system manufacturing costs.

The present invention aims to solve the problems in the conventional technology described above, and to provide an opening and closing control system that makes it possible to reduce manufacturing costs.

In order to solve the above-mentioned problems and achieve the object, the opening/closing control system described in claim 1 is an opening/closing body that constitutes an automatic door device installed in a target space, and is an opening/closing control system for controlling the opening/closing movement of the opening/closing body that opens and closes a target opening/closing area in the target space, and is equipped with: a detection means for detecting that an opening/closing timing has arrived to start the opening/closing movement of the opening/closing body; an opening/closing state identification means for identifying the opening/closing state of the opening/closing body; a general-purpose control device that is a normally-closed specification and is configured with a first opening/closing control means that controls the opening/closing movement of the opening/closing body; and a second opening/closing control means configured separately from the first opening/closing control means and that controls the first opening/closing control means based on the detection result of the detection means and the identification result of the opening/closing state identification means, and the second opening/closing control means transmits or does not transmit an activation signal indicating an instruction to open the opening/closing body to the first opening/closing control means depending on the detection result of the detection means and the identification result of the opening/closing state identification means, thereby enabling control of the opening/closing movement of the opening/closing body depending on a standby position that is a position for waiting for the opening/closing movement of the opening/closing body.

The opening and closing control system of claim 2 is the opening and closing control system of claim 1, wherein the detection means includes an inner detection means for detecting an inner opening and closing action performed by a user present inside the target space and which serves as a trigger for starting the opening and closing action of the opening and closing body, and the second opening and closing control means controls the first opening and closing control means to maintain the opening and closing state of the opening and closing body in the fully open state by sending the activation signal to the first opening and closing control means if the inner opening and closing action is not detected by the inner detection means when the fully open state is identified by the opening and closing state identification means, and controls the first opening and closing control means to change the opening and closing state of the opening and closing body to the fully closed state in which the opening and closing target area is fully closed by the opening and closing body by not sending the activation signal to the first opening and closing control means when the inner opening and closing action is detected by the inner detection means when the fully open state is identified by the opening and closing state identification means.

The opening/closing control system of claim 3 is the opening/closing control system of claim 2, wherein the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully closed state by not sending the activation signal to the first opening/closing control means if the fully closed state is identified by the opening/closing state identification means and the inner opening/closing operation is not detected by the inner detection means, and controls the first opening/closing control means to change the opening/closing state of the opening/closing body to the fully open state by sending the activation signal to the first opening/closing control means if the inner opening/closing operation is detected by the inner detection means when the fully closed state is identified by the opening /closing state identification means.

The opening/closing control system of claim 4 is the opening/closing control system of claim 2 or 3, wherein, after the opening/closing body is positioned to the standby position, when the opening/closing state identification means identifies a half-open state, which is a state between the fully closed state and the fully closed state, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the half-open state regardless of the detection result of the inside detection means, and when the identified half-open state is a half-open open movement state in which the opening/closing body is moved open, the start signal is sent to the first opening/closing control means to continue the opening movement of the opening/closing body by the first opening/closing control means, and when the identified half-open state is a half-open closed movement state in which the opening/closing body is moved closed, the start signal is not sent to the first opening/closing control means to continue the closing movement of the opening/closing body by the first opening/closing control means.

The opening/closing control system according to claim 1 includes a detection means for detecting the arrival of the opening/closing timing for starting the opening/closing movement of the opening/closing body, an opening/closing state identification means for identifying the opening/closing state of the opening/closing body, a first opening/closing control means for controlling the opening/closing movement of the opening/closing body, and a second opening/closing control means configured separately from the first opening/closing control means and for controlling the first opening/closing control means based on the detection result of the detection means and the identification result of the opening/closing state identification means. This makes it unnecessary to change the control content of the opening/closing control system according to the standby position of the opening/closing body, and allows the opening/closing movement of the opening/closing body to be controlled using a general-purpose control device as is, thereby reducing the manufacturing cost of the opening/closing control system.

According to the opening/closing control system described in claim 2, after the second opening/closing control means has positioned the opening/closing body to the standby position, if the fully open state is identified by the opening/closing state identification means and no inner opening/closing operation is detected by the inner detection means, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully open state, and if the fully open state is identified by the opening/closing state identification means and an inner opening/closing operation is detected by the inner detection means, the first opening/closing control means controls the opening/closing state of the opening/closing body to be in the fully closed state in which the opening/closing target area is fully closed by the opening/closing body. Therefore, when the standby position is set to the fully open position, the opening/closing movement of the opening/closing body can be performed according to the usage status of the target space by the user, and the usability of the opening/closing control system can be improved.

According to the opening/closing control system described in claim 3, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully closed state if the fully closed state is identified by the opening/closing state identification means and an inner opening/closing operation is not detected by the inner detection means after the opening/closing body is positioned at the standby position, and controls the first opening/closing control means to set the opening/closing state of the opening/closing body to the fully open state if an inner opening/closing operation is detected by the inner detection means when the fully closed state is identified by the opening/closing state identification means. Therefore, when the standby position is set to the fully open position, the opening/closing body can be opened/closed according to the usage status of the target space by the user, and the usability of the opening/closing control system can be further improved. In addition, the user can smoothly enter and exit the target space using only the inner detection means, and the installation cost of the opening/closing control system can be reduced.

According to the opening/closing control system described in claim 4, when the opening/closing state specifying means specifies a half-open state, which is a state between the fully closed state and the fully closed state, after the second opening/closing control means has positioned the opening/closing body to the standby position, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the half-open state regardless of the detection result of the inner detection means. This makes it possible to avoid a situation in which the half-open state is not maintained due to the detection result of the inner detection means when the opening/closing body is in the half-open state, thereby improving the usability of the opening/closing control system.

First, [I] the basic concept of the embodiment is explained, then [II] the specific content of the embodiment is explained, and finally, [III] modified examples of the embodiment are explained. However, the present invention is not limited to the embodiment.

[I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment generally relates to an opening/closing control system for controlling the opening/closing movement of an opening/closing body that constitutes an automatic door device installed in a target space and that opens and closes a target opening/closing area in the target space.

Here, "target space" refers to the space in which the automatic door device is to be installed, and is a concept that includes, for example, toilet booths, changing rooms, conference rooms, etc., provided in a building.

The term "building" can refer to any specific structure or type, but it is a concept that includes, for example, commercial facilities, office buildings, public facilities, and apartment complexes such as apartments and condominiums, but in this embodiment, it will be described as a commercial facility.

The "area to be opened and closed" refers to the area of the target space that is the target to be opened and closed by the opening and closing body, and is a concept that includes, for example, an entrance and exit (opening) formed in a side wall surrounding the target space.

In addition, "opening and closing body" refers to a structure that prevents or restricts entry and exit to an area to be opened and closed in a target space, and is a concept that includes, for example, opening and closing bodies for automatic door systems.

The opening and closing structure of the opening and closing body is arbitrary, and can be configured as, for example, a single-opening door, a double-opening door, a single-sliding door, a sliding door, or a folding door.

In addition, in the embodiment, the "open/close state of the opening/closing body" is a concept that includes a fully closed state, a fully open state, and a half-open state.

The "fully closed state" refers to a state in which the opening/closing target area is fully closed by the opening/closing body, and the position of the opening/closing body in this fully closed state is referred to as the "fully closed position."

The "fully open state" refers to the state in which the opening/closing target area is fully opened by the opening/closing body, and the position of the opening/closing body in this fully open state is referred to as the "fully open position."

The "half-open state" refers to a state in which the opening/closing body is located between the fully closed position and the fully open position, and is a concept that includes a "half-open stopped state" in which a part of the opening/closing target area is open and stopped, a "half-open open movement state" in which the opening/closing body is moved to the open position, and a "half-open closed movement state" in which the opening/closing body is moved to the closed position. The position of the opening/closing body in this half-open state is referred to as the "half-open position."

In the following embodiment, we will explain a case where the opening and closing body of the automatic door device is a circular single-sliding door installed at the entrance (target opening and closing area) of a toilet booth (target space).

[II] Specific Contents of the Embodiment Next, specific contents of the embodiment will be described.

(composition)
First, the configuration of an automatic door system to which an opening/closing control system according to an embodiment of the present invention is applied will be described.

In the following explanation, the X direction in Figure 1 is referred to as the left-right direction of the automatic door device (-X direction is the left direction of the automatic door device, +X direction is the right direction of the automatic door device), the Y direction in Figure 1 is referred to as the front-to-back direction of the automatic door device (+Y direction is the front direction of the automatic door device (toward the outside of the target space) and -Y direction is the rear direction of the automatic door device (toward the inside of the target space)), and the Z direction in Figure 1 is referred to as the up-down direction of the automatic door device (+Z direction is the upward direction of the automatic door device, -Z direction is the downward direction of the automatic door device).

The automatic door device 1 is a device for opening and closing a target area 3 (specifically, an entrance/exit) in a target space 2 (specifically, a toilet booth). As shown in Figures 1 and 2, the automatic door device 1 is provided in the front part of the target space 2, and includes a guide rail unit 10, an opening/closing body 20, an opening/closing drive unit 31, a lock unit 32, an output unit 33, and an opening/closing control system 40.

The connection configuration of each component that makes up this automatic door device 1 is set as shown below. That is, the control device 50 of the opening/closing control system 40 described later is electrically connected via wiring 4 to the opening/closing drive unit 31, lock unit 32, output unit 33, inside detection unit 41, position detection unit 42, and switching unit 44 of the opening/closing control system 40 described later. This allows communication or power supply directly or indirectly between the control device 50 described later and the opening/closing drive unit 31, lock unit 32, output unit 33, inside detection unit 41, position detection unit 42, and switching unit 44 of the opening/closing control system 40 described later.

The various components that make up the automatic door system 1 may be attached (or connected) in any manner, but examples of methods that can be used include attaching (or connecting) the component on the attachment side to the component on the other side via mounting holes (e.g. rivet holes, screw holes, screw holes, etc.) formed in the component on the attachment side or the component on the other side using fasteners (e.g. rivets, mounting screws, screws, etc.), welding, adhesives, double-sided tape, etc.

(Composition - target space)
Returning to Fig. 1, the target space 2 is surrounded by a plurality of walls 5 (e.g., known wall panels, etc.) as shown in Fig. 1 and Fig. 2. A toilet 6 is provided inside the target space 2.

The multiple walls 5 are composed of a left wall 5a, a right wall 5b, a front wall 5c, and a rear wall 5d. The front wall 5c is further composed of a leading wall 5e located on the leading side of the opening/closing body 20, and a trailing wall 5f located on the trailing side of the opening/closing body 20. The opening/closing target area 3 is provided between the leading wall 5e and the trailing wall 5f.

The toilet bowl 6 receives the user's urine and urine, and is constructed, for example, using a known toilet device, and is placed inside the target space 2 in a position that does not interfere with the opening and closing movement of the opening/closing body 20 (in Figure 2, it is located at the rear of the target space 2).

(Configuration: Guide rail section)
The guide rail portion 10 guides the opening/closing body 20 to move substantially along the opening/closing direction (left/right direction) of the target opening/closing area 3. The guide rail portion 10 is a curved, elongated body formed so that its vertical cross section is substantially U-shaped, and is disposed substantially horizontally at or near the upper end of the target space 2. The guide rail portion 10 is directly fixed to the left side wall portion 5a, the right side wall portion 5b, and/or the front side wall portion 5c, or is indirectly fixed via a base material 11.

(Configuration - Opening and closing body)
Returning to Fig. 1, the opening/closing body 20 is for opening and closing the target opening/closing area 3 of the target space 2. The opening/closing body 20 is configured, for example, using a known opening/closing body for an automatic door system (one example is an opening/closing panel for a circular single-sliding automatic door system). Specifically, it includes an opening/closing body frame (not shown) made of steel (for example, steel, stainless steel, etc.) and a surface material 21 (for example, a resin decorative panel, etc.) attached so as to cover the entire side surface in the prospective direction (front-rear direction) of the opening/closing body frame.

The opening/closing body 20 is also provided with a guided portion (not shown). The guided portion is for sliding the opening/closing body 20 on the guide rail portion 10. This guided portion is configured using, for example, a known guide roller or the like, and is attached so as to be slidable relative to the guide rail portion 10, and is connected to the opening/closing body 20 by a fixing device or the like.

The specific configuration of the opening/closing body 20 is optional, but in the embodiment, when the opening/closing body 20 is moved to open, the guided portion comes into contact with the end of the guide rail portion 10 on the tail side, thereby restricting the opening/closing body 20 from moving beyond the fully open position. When the opening/closing body 20 is moved to close, the door end side portion of the opening/closing body 20 comes into contact with the door stopper portion 5g provided on the door end side wall portion 5e, thereby restricting the opening/closing body 20 from moving beyond the fully closed position.

(Configuration: Opening/Closing Drive Unit)
The opening/closing drive unit 31 is an opening/closing drive means for electrically opening and closing the opening/closing body 20. This opening/closing drive unit 31 is configured using, for example, a known opening/closing drive means for a sliding door type automatic door device, and as shown in Figures 1 and 2, is provided on the door trailing end portion of the guide rail unit 10 and fixed to the guide rail unit 10 by a fixture or the like.

(Configuration - Lock part)
Returning to Fig. 1, the lock unit 32 is a device for locking the opening/closing body 20. This lock unit 32 is configured using, for example, an electric lock for an automatic door system, and as shown in Fig. 1, is provided on the guide rail unit 10 and fixed to the guide rail unit 10 by a fixture or the like.

The specific operation when the lock unit 32 is an electric lock is arbitrary, but may be as follows, for example. That is, in the normal opening and closing process described below, when the second full-close control described below is being performed, the lock unit 32 locks the opening and closing body 20, and when the first full-close control described below, the first full-open control described below, or the second full-open control described below is being performed, the lock unit 32 releases the lock on the opening and closing body 20.

(Configuration - Output section)
The output unit 33 is an output means for outputting the usage status of the target space 2 .

Here, the "usage status of the target space 2" is a concept that includes, for example, an occupancy status indicating whether or not a user is present in the target space 2, an abnormality status indicating whether or not an abnormality has occurred inside the target space 2, etc., but in the embodiment, it will be described as an occupancy status.

This output unit 33 is configured, for example, using a known output device (such as an indicator light, for example), and as shown in FIG. 1, is provided on the door end side wall 5e outside the target space 2, and is fixed to the door end side wall 5e by a fixing device or the like.

The output operation of the output unit 33 is arbitrary, but is, for example, as shown below. That is, when the position of the opening/closing body 20 is the fully open position or the half-open position, it is determined that a user is not present in the target space 2, and the output unit 33 is turned off. On the other hand, when the position of the opening/closing body 20 is the fully closed position, it is determined that a user is present in the target space 2, and the output unit 33 is turned on in red.

(Configuration - Opening and closing control system)
The opening/closing control system 40 is a system for controlling the opening/closing movement of the opening/closing body 20, and as shown in Figs. 1 and 2, includes an inside detection unit 41, a position detection unit 42, a switching unit 44, and a control device 50.

(Configuration - Opening and closing control system - Inside detection section)
The inside detection unit 41 is a detection means that detects the arrival of an opening/closing timing described later, and is an inside detection means that detects an inside opening/closing operation.

Here, "inner opening/closing action" refers to an action performed by a user present inside the target space 2, which is an action that serves as a trigger to start the opening/closing action of the opening/closing body 20.

This inner detection unit 41 is configured, for example, using a publicly known detection sensor for an automatic door system (one example is a publicly known non-contact detection sensor such as a transmission type photoelectric sensor), and specifically includes a light-transmitting unit that irradiates detection light, and a light-receiving unit that is located above the light-transmitting unit and receives the detection light irradiated from the light-receiving unit (both not shown). As shown in FIG. 2, this inner detection unit 41 is provided on the left side wall 5a inside the target space 2, and is fixed to the left side wall 5a by a fixture or the like.

When the inner detection unit 41 is a transmission type photoelectric sensor, the detection operation is, for example, as shown below. That is, when the detection light emitted from the light transmission unit of the inner detection unit 41 is blocked by a user's finger or the like, and the light receiving unit of the inner detection unit 41 cannot receive the detection light, a signal including information indicating that an inner opening/closing operation has been detected (hereinafter referred to as an "inner opening/closing operation signal") is output. On the other hand, when the light receiving unit can receive the detection light, the inner opening/closing operation signal is not output.

(Configuration - Opening and closing control system - Position detection unit)
The position detection unit 42 is a position detection means that detects the position of the opening/closing body 20. The position detection unit 42 is configured using a known detection sensor such as a rotary encoder, and is provided in the vicinity of the opening/closing drive unit 31 and fixed to the opening/closing drive unit 31 by a fixing device or the like.

When the position detection unit 42 is a rotary encoder, the detection operation involves, for example, counting the number of pulses output according to the position of the opening/closing body 20 from an origin position (fully closed position in the embodiment) using a counting means (not shown), and outputting a signal (hereinafter referred to as a "position detection signal") that includes count value information indicating the counted value.

(Configuration - Switching control system - Switching section)
The switching unit 44 is a switching means that switches the power supply state (hereinafter simply referred to as the “power supply state”) from an external power source (not shown) to the opening and closing control system 40 between a state in which power supply is continued (hereinafter referred to as the “continued state”) and a state in which power supply is cut off (hereinafter referred to as the “cut off state”).

Here, "cutting off the power supply" means that the user (or other worker) intentionally stops the power supply from the external power source using the switching unit 44.

The term "external power source" refers to a power source provided outside the opening and closing control system 40, and is a concept that includes, for example, a commercial power source.

This switching unit 44 is configured using, for example, a known switching means (such as a button-type switch) and is provided in the control device 50 as shown in FIG. 1.

Furthermore, when the switching unit 44 is a button-type switch, the specific operation is arbitrary, but is, for example, as shown below. That is, when the switching unit 44 switches the power supply state from a cut-off state to a continuous state due to the operation of the user (or other worker), it outputs a signal indicating that (hereinafter referred to as a "switching signal"). On the other hand, when the switching unit 44 switches the power supply state from a continuous state to a cut-off state due to the operation of the user (or other worker), it does not output a switching signal.

(Configuration - Switching control system - Control device)
The control device 50 is a device for controlling the opening and closing control system 40, and as shown in FIG. 3, includes a first control unit 60 and a second control unit 70.

(Configuration-Opening and Closing Control System-Control Device-First Control Unit)
3, the first control unit 60 includes a first communication unit 61, a first power supply unit 62, a first control unit 63, and a first storage unit 64. However, unless otherwise specified, the configuration of the first control unit 60 is the same as that of a general-purpose control device for a conventional automatic door system (specifically, a general-purpose control device for a normally-closed door), and therefore a description thereof will be omitted.

(Configuration-Opening and closing control system-Control device-First control unit-First communication unit)
The first communication section 61 is a first communication means for communicating with the opening/closing drive section 31 , the position detection section 42 , and the second control unit 70 via the wiring 4 .

(Configuration-Switching control system-Control device-First control unit-First power supply unit)
The first power supply unit 62 is a first power supply means that supplies power supplied from an external power source to each part of the first control unit 60 via wiring 4, and also supplies power to the opening/closing drive unit 31 and the position detection unit 42 via wiring 4.

(Configuration-Opening and closing control system-Control device-First control unit-First control section)
The first control unit 63 is a control means that controls each part of the first control unit 60. Specifically, the first control unit 63 is a computer that includes a CPU, various programs that are interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are started on the OS and realize specific functions), and an internal memory such as a RAM for storing the programs and various data (note that the configuration of the second control unit 73 described later is substantially the same).

Furthermore, as shown in FIG. 3, the first control unit 63 is functionally and conceptually equipped with a first opening/closing control unit 63a.

The first opening/closing control unit 63a is an opening/closing control means that performs normal opening/closing control and learning opening/closing control, and is also a first opening/closing control means that controls the opening/closing movement of the opening/closing body 20.

Here, "normal opening/closing control" refers to control that opens and closes the opening/closing body 20 based on the detection results of the inner detection unit 41.

"Learning opening/closing control" refers to control that is performed at a predetermined timing before normal opening/closing control is performed, and it refers to control that identifies the fully open position and the fully closed position by moving the opening/closing body 20 to open and close.

In addition, in the embodiment, the above-mentioned predetermined timing is a concept that includes the timing when the opening/closing process described below is started, the return timing, the switching timing, etc.

Among these, "return timing" refers to the timing at which the supply of power from an external power source to the opening/closing control system 40 is stopped and then restored. Also, "power supply being stopped" refers to the power supply from the external power source being stopped against the will of the user (or other worker), for example, when the power supply is stopped due to an external factor (such as a power outage, a broken power line, or the automatic door device 1 being unplugged, etc.).

In addition, "switching timing" refers to the timing at which the power supply state is switched from a cut-off state to a continuous state by the switching unit 44.

The reason why the learning opening/closing control is executed when the opening/closing process described below is activated is to identify the fully closed position and the fully open position so that the opening/closing body 20 can be opened and closed accurately with the fully closed position as the base position for control.

The reason for executing the learning opening/closing control after the restoration timing is as follows. That is, if the opening/closing movement of the opening/closing body 20 is manually performed while the supply of power from an external power source to the opening/closing control system 40 is stopped, the position of the opening/closing body 20 will shift, and the position detection unit 42 will not be able to accurately detect the position of the opening/closing body 20 when the power supply is restored. As a result, there is a risk that the opening/closing movement of the opening/closing body 20 will not be able to be performed accurately after the restoration, and this is to avoid such a problem from occurring (note that the reason for executing the learning opening/closing control after the switching timing is substantially the same).

The specific control contents of the first opening/closing control unit 63a are arbitrary, but in the embodiment, they are as follows.

That is, in the opening and closing process described below, the learning opening and closing control is executed after the timing when the opening and closing process described below is started, after the return timing, and after the switching timing. However, as described below, even after the return timing, if a learning stop signal (a signal to stop the execution of the learning opening and closing control) is received from the second opening and closing control unit 73a, the execution of the learning opening and closing control is stopped until the learning stop signal is no longer received, thereby preventing the opening and closing body 20 from moving open or closed against the user's intention.

Furthermore, in at least the processes SA7 and SA8 of the opening and closing process described below, if a start signal described below is not received from the second opening and closing control unit 73a and the opening and closing body 20 is in the fully open or half open position, a close signal (a signal to move the opening and closing body 20 to the closed position) is output to the opening and closing drive unit 31, causing the opening and closing body 20 to move to the closed position by the opening and closing drive unit 31. Furthermore, when the opening and closing body 20 is in the fully closed position, a stop signal (a signal to stop the opening and closing movement of the opening and closing body 20) is output to the opening and closing drive unit 31, causing the opening and closing movement of the opening and closing body 20 to be stopped by the opening and closing drive unit 31.

Furthermore, in at least the processes SA7 and SA8 of the opening and closing process described below, when an activation signal described below is received from the second opening and closing control unit 73a, if the opening and closing body 20 is in the fully closed or half-open position, an open signal (a signal to move the opening and closing body 20 open) is output to the opening and closing drive unit 31, causing the opening and closing body 20 to move open by the opening and closing drive unit 31. Also, if the opening and closing body 20 is in the fully open position, a stop signal is output to the opening and closing drive unit 31, causing the opening and closing drive unit 31 to stop the opening and closing movement of the opening and closing body 20. Details of the process executed by this first control unit 63 will be described later.

(Configuration-Opening and closing control system-Control device-First control unit-First storage unit)
The first memory unit 64 is a first storage means for storing programs and various data necessary for the operation of the first control unit 60, and is constructed using a rewritable recording medium, and may use a non-volatile recording medium such as a flash memory (note that the configuration of the second memory unit 74 described later is approximately the same).

(Configuration-Opening and closing control system-Control device-Second control unit)
The second control unit 70 is a unit that controls the first control unit 60 and is configured separately from the first control unit 60 (i.e., the second opening/closing control unit 73a described below is configured separately from the first opening/closing control unit 63a), and as shown in FIG. 3, includes a second communication unit 71, a second power supply unit 72, a second control unit 73, and a second memory unit 74.

The second communication unit 71 is a second communication means for communicating between the lock unit 32, the output unit 33, the inside detection unit 41, the position detection unit 42, the switching unit 44, and the first control unit 60 via the wiring 4.

(Configuration-Switching control system-Control device-Second control unit-Second power supply unit)
The second power supply unit 72 is a second power supply means that supplies power supplied from an external power source to each part of the second control unit 70 via wiring 4, and also supplies power to the lock unit 32, output unit 33, inner detection unit 41, position detection unit 42, and switching unit 44 via wiring 4.

(Configuration-Opening and closing control system-Control device-Second control unit-Second control section)
The second control section 73 is a control means for controlling each section of the second control unit 70, and as shown in FIG. 3, conceptually includes a second opening/closing control section 73a and an opening/closing state specifying section 73b.

The second opening/closing control unit 73a is an opening/closing control means that performs normal opening/closing control and learning opening/closing control, and also controls the first opening/closing control unit 63a based on the detection result of the inside detection unit 41 and the identification result of the opening/closing state identification unit 73b.

The specific control contents of the second opening/closing control unit 73a are arbitrary, but in the embodiment, this corresponds to controlling the first opening/closing control unit 63a by sending or not sending a signal indicating an instruction to move the opening/closing body 20 to the open position (hereinafter referred to as the "start signal") or a learning stop signal to the first opening/closing control unit 63a depending on the processing contents of the opening/closing process described below.

The open/close state determination unit 73b is an open/close state determination means that determines the open/close state of the opening/closing body 20. Details of the processing executed by this second control unit 73 will be described later.

(Configuration-Opening and closing control system-Control device-Second control unit-Second memory unit)
The second storage section 74 is a second storage means for storing programs and various data necessary for the operation of the second control unit 70 .

Since such an opening/closing control system 40 can execute the opening/closing process described below, when the return timing arrives while the user is using the target space 2, it is possible to prevent the opening/closing body 20 from moving open or closed against the user's intention, thereby improving the usability of the opening/closing control system 40. Also, compared to a case in which an emergency power supply device is provided in the opening/closing control system 40, the opening/closing control system 40 can be manufactured at low cost, and the installation costs of the opening/closing control system 40 can be reduced. Furthermore, there is no need to change the control content of the opening/closing control system 40 depending on the standby position of the opening/closing body 20, and the opening/closing movement of the opening/closing body 20 can be controlled using a general-purpose control device as is, thereby reducing the manufacturing costs of the opening/closing control system 40.

(Opening and closing process)
Next, a description will be given of the opening and closing process executed by the first control section 63 of the first control unit 60 and the second control section 73 of the second control unit 70 configured as described above. In the following description, steps will be abbreviated as "S" in the description of each process shown in Figs.

The opening and closing process is a process for controlling the opening and closing movement of the opening and closing body 20. The timing for executing this opening and closing process is arbitrary, but in this embodiment, it is described as being started after the power of the automatic door device 1 is turned on.

In addition, the premise of the opening and closing process in this embodiment is as follows. That is, although not shown in FIG. 4, it is assumed that immediately after the opening and closing process is started when the automatic door device 1 is installed, the learning opening and closing process (SA5) described below has already been executed and the opening and closing body 20 is positioned in a standby position described below. Also, although not shown in FIG. 4, the first control unit 63 monitors whether the supply of power from an external power source to the opening and closing control system 40 has been stopped or cut off, and also monitors whether the supply of power has been restored if the supply of power has been stopped or cut off.

As shown in FIG. 4, in SA1, the second control unit 73 determines whether the supply of power from an external power source to the opening and closing control system 40 has been stopped.

Specifically, the system makes a determination based on whether the amount of power supplied from the external power source is less than a threshold value. If the amount is less than the threshold value, it determines that the supply of power has been stopped, and if the amount is not less than the threshold value, it determines that the supply of power has not been stopped.

Then, if the second control unit 73 determines that the power supply is stopped (SA1, Yes), it transitions to SA2, and if it determines that the power supply is not stopped (SA1, No), it transitions to SA4.

At SA2, the second opening/closing control unit 73a determines whether the return timing has arrived.

While the method for determining whether or not the timing to return has arrived is arbitrary, in this embodiment, the operation history information (information indicating various operations of the automatic door device 1) stored in the second memory unit 74 is referenced to determine whether or not the amount of power supplied from the external power source has reached or exceeded a threshold immediately after the supply of power from the external power source has started after it has been determined that the supply of power has been stopped at SA2 since the opening/closing process was initiated (specifically, after the amount of power supplied from the external power source has fallen below a threshold). If the amount of power supplied is above the threshold, it is determined that the timing to return has arrived, and if the amount of power is not above the threshold, it is determined that the timing to return has not arrived.

The second opening/closing control unit 73a then waits until it is determined that the return timing has arrived (SA2, No). If it is determined that the return timing has arrived (SA2, Yes), the process proceeds to SA3. Furthermore, by transmitting a learning stop signal to the first opening/closing control unit 63a until it is determined in SA3 that the opening/closing timing described below has arrived, the first opening/closing control unit 63a stops executing the learning opening/closing process (SA5) described below when the return timing arrives.

In SA3, the second opening/closing control unit 73a determines whether the timing to start the opening/closing movement of the opening/closing body 20 (hereinafter referred to as the "opening/closing timing") has arrived.

While the method for determining whether or not the opening/closing timing has arrived is arbitrary, in the embodiment, the determination is made based on whether or not an inner opening/closing operation signal has been received from the inner detection unit 41, and if an inner opening/closing operation signal has been received, it is determined that the opening/closing timing has arrived, and if an inner opening/closing operation signal has not been received, it is determined that the opening/closing timing has not arrived.

Then, the second opening/closing control unit 73a waits until it is determined that the opening/closing timing has arrived (SA3, No), and if it is determined that the opening/closing timing has arrived (SA3, Yes), it stops sending a learning stop signal to the first opening/closing control unit 63a, thereby causing the first opening/closing control unit 63a to execute the learning opening/closing process (SA5).

By performing the processes from SA1 to SA3 and SA5 in this manner, when the return timing arrives while the user is using the target space 2, it is possible to prevent the opening/closing body 20 from opening or closing against the user's intention, compared to when a learning operation is performed when the opening/closing control system 40 is powered on, thereby improving the usability of the opening/closing control system 40. Also, compared to when an emergency power supply device is provided in the opening/closing control system 40, the opening/closing control system 40 can be manufactured more inexpensively, and the installation costs of the opening/closing control system 40 can be reduced.

In SA4, the second opening/closing control unit 73a determines whether the switching timing has arrived.

While the method for determining whether or not this switching timing has arrived is arbitrary, in the embodiment, after the power supply state is switched from a continuous state to a cutoff state by the switching unit 44, the determination is made based on whether or not a switching signal has been received. If the switching signal has been received, it is determined that the switching timing has arrived, and if the switching signal has not been received, it is determined that the switching timing has not arrived.

Then, when the second opening/closing control unit 73a determines that the switching timing has arrived (SA4, Yes), it causes the first opening/closing control unit 63a to execute the learning opening/closing process (SA5) without sending a learning stop signal to the first opening/closing control unit 63a (i.e., causes the learning opening/closing process (SA5) to be executed regardless of the detection result of the inside detection unit 41), and when it determines that the switching timing has not arrived (SA4, No), it starts the normal opening/closing process (SA8).

By performing this type of processing, when the switching timing arrives, the learning opening/closing process can be performed more quickly than when the return timing arrives, thereby further improving the usability of the opening/closing control system 40.

(Opening/Closing Process - Learning Opening/Closing Process)
Next, the learning opening/closing process at SA5 in FIG. 4 will be described.

The learning opening/closing process is a process for performing learning opening/closing control, and in the embodiment, it is described as being executed based on a program built into the first control unit 60.

When the learning opening/closing process is started, as shown in FIG. 5, in SB1, the first opening/closing control unit 63a moves the opening/closing body 20 to open using the opening/closing drive unit 31. Specifically, this opening movement is performed until it is determined in SB2 described below that the load amount of the opening/closing drive unit 31 is equal to or greater than a threshold value (more specifically, the opening/closing body 20 is moved to open at a slower speed than in the first full-open control in SC8 described below).

At SB2, the first opening/closing control unit 63a determines whether the load on the opening/closing drive unit 31 is equal to or greater than a threshold value.

Then, the first opening/closing control unit 63a waits until it is determined that the threshold value is equal to or greater than the threshold value (SB2, No), and if it is determined that the threshold value is equal to or greater than the threshold value (SB2, Yes), it proceeds to SB3.

At SB3, the first opening/closing control unit 63a identifies the fully open position.

The method for identifying this fully open position is arbitrary, but in this embodiment, the position of the opening/closing body 20 corresponding to the position detection signal (specifically, the count value information included in the position detection signal) received from the position detection unit 42 immediately before processing SB3 is identified as the fully open position.

In SB4, the first opening/closing control unit 63a moves the opening/closing body 20 to the closed position by the opening/closing drive unit 31. Specifically, the opening/closing movement is continued until it is determined in SB5 (described later) that the load on the opening/closing drive unit 31 is equal to or greater than a threshold value and the movement distance of the opening/closing body 20 has reached a predetermined value (more specifically, the opening/closing body 20 is moved to the closed position at a slower speed than in the first full-close control in SC4 (described later).)

The method for setting this predetermined value is arbitrary, but for example, it may be set based on travel distance information stored in the second memory unit 74 (or the first memory unit 64) that indicates the travel distance (so-called stroke) of the opening/closing body 20 from the fully open position to the fully closed position, or it may be set based on travel distance information received from an external device (for example, a terminal device, etc.).

In SB5, the first opening/closing control unit 63a determines whether the load amount of the opening/closing drive unit 31 is equal to or greater than a threshold value and, based on the detection result of the position detection unit 42, whether the movement distance of the opening/closing body 20 since the processing of SB4 is completed (specifically, the movement distance due to the closing movement of the opening/closing body 20) has reached a predetermined value (the movement distance indicated by the movement distance information). However, this is not limited to this, and for example, the determination may be made only based on whether it is equal to or greater than the threshold value, or only based on whether the movement distance of the opening/closing body 20 has reached a predetermined value.

Then, the first opening/closing control unit 63a waits until it is determined that the threshold value is equal to or greater than the threshold value and that the distance traveled by the opening/closing body 20 has reached a predetermined value (SB5, No), and if it is determined that the threshold value is equal to or greater than the threshold value and that the distance traveled by the opening/closing body 20 has reached a predetermined value (SB5, Yes), it proceeds to SB6.

In SB6, the first opening/closing control unit 63a identifies the fully closed position and ends the learning opening/closing process. Then, the second opening/closing control unit 73a transitions to SA6 in FIG. 4, triggered by the end of the learning opening/closing process.

The method for identifying the fully closed position is arbitrary, but in this embodiment, the position of the opening/closing body 20 corresponding to the position detection signal received from the position detection unit 42 immediately before processing SB6 is identified as the fully closed position.

By using the above learning opening and closing process, the fully open and fully closed positions can be identified.

Returning to FIG. 4, in SA6, the second opening/closing control unit 73a determines whether the opening/closing body 20 is in the standby position.

Here, the "standby position" refers to a position where the opening/closing body 20 waits for opening/closing movement, and in the embodiment, it is described as being the same position as the fully open position.

While the method for determining whether the position of the opening/closing body 20 is the standby position is arbitrary, in this embodiment, the determination is made based on whether the position of the opening/closing body 20 corresponding to the position detection signal received from the position detection unit 42 immediately before processing SA6 matches the fully open position identified in SB3, and if they match, it is determined to be the standby position, and if they do not match, it is determined to be not the standby position.

Then, if the second opening/closing control unit 73a determines that the opening/closing body 20 is in the standby position (SA6, Yes), it starts the normal opening/closing process (SA8) (i.e., it performs the normal opening/closing process after the learning opening/closing process). On the other hand, if it determines that the opening/closing body 20 is not in the standby position (SA6, No), it transitions to SA7.

In SA7, the second opening/closing control unit 73a performs adjusted opening/closing control, and then starts normal opening/closing processing (SA8) (i.e., normal opening/closing processing is performed after learning opening/closing processing is performed).

Here, "adjusted opening/closing control" means control that moves the opening/closing body 20 to the standby position before normal opening/closing control is performed if the position of the opening/closing body 20 detected by the position detection unit 42 immediately after learning opening/closing control is not the standby position.

The specific control content of the adjusted opening/closing control is arbitrary, but in the embodiment, the second opening/closing control unit 73a sends an activation signal to the first opening/closing control unit 63a, causing the second opening/closing control unit 73a to move the opening/closing body 20 to open until the opening/closing body 20 reaches the standby position (fully open position).

The method of transmitting this activation signal is arbitrary, but in the embodiment, the activation signal is transmitted continuously while the adjusted opening/closing control is being executed. However, this is not limited to this, and for example, the activation signal may be transmitted intermittently, or may be transmitted only once (so-called pulse transmission) (the same applies to the first full-open control and the second full-open control described below).

By performing this process, the opening/closing body 20 can be automatically moved to the standby position after the learning opening/closing control has been performed, making it possible to smoothly perform normal opening/closing control.

(Opening and closing process - normal opening and closing process)
Next, the normal opening/closing process at SA8 in FIG. 4 will be described.

The normal opening and closing process is a process for performing normal opening and closing control.

When the normal opening/closing process is started, the opening/closing state determination unit 73b determines the opening/closing state of the opening/closing body 20 in SC1, as shown in FIG. 6.

The method for identifying the open/close state of the opening/closing body 20 is arbitrary, but in the embodiment, the state is identified based on the position detection signal received from the position detection unit 42 immediately before processing SC1 and the control signal (specifically, the close signal, open signal, stop signal) output from the first control unit 63 to the opening/closing drive unit 31 immediately before processing SC1.

For example, if the position of the opening/closing body 20 corresponding to the position detection signal is the fully open position and the control signal is a stop signal, it is identified as a fully open state. Also, if the position of the opening/closing body 20 corresponding to the position detection signal is the fully closed position and the control signal is a stop signal, it is identified as a fully open state. Also, if the position of the opening/closing body 20 corresponding to the position detection signal is the half-open position and the control signal is a close signal, it is identified as a half-open closed movement state. Also, if the position of the opening/closing body 20 corresponding to the position detection signal is the half-open position and the control signal is an open signal, it is identified as a half-open open movement state.

In SC2, the opening/closing state determination unit 73b determines whether the opening/closing state of the opening/closing body 20 determined in SC1 is fully open or not.

Then, if the open/close state determination unit 73b determines that the door is fully open (SC2, Yes), it transitions to SC3, and if it determines that the door is not fully open (SC2, No), it transitions to SC6.

In SC3, the second opening/closing control unit 73a determines whether or not an inside opening/closing operation signal has been received from the inside detection unit 41.

Then, if the second opening/closing control unit 73a determines that it has received an inside opening/closing operation signal (SC3, Yes), it transitions to SC4, and if it determines that it has not received an inside opening/closing operation signal (SC3, No), it transitions to SC5.

In SC4, the second opening/closing control unit 73a performs the first full-close control. After that, the normal opening/closing process ends and the process proceeds to SA1, and thereafter the processes from SA1 to SA8 are repeated in the same manner.

Here, "first full-close control" means controlling the first opening/closing control unit 63a so that the position of the opening/closing body 20 is in the fully closed position.

The specific control content of the first full-close control is arbitrary, but in this embodiment, the second opening/closing control unit 73a does not send an activation signal to the first opening/closing control unit 63a until the opening/closing body 20 reaches a position a predetermined distance away from the full-open position in the closing direction, thereby causing the first opening/closing control unit 63a to move the opening/closing body 20 to the closed position.

The method for setting this specified distance is arbitrary, but for example, it may be set based on travel distance information stored in the second storage unit 74 (or the first storage unit 64), or it may be set based on travel distance information received from an external device (for example, a terminal device, etc.).

In SC5, the second opening/closing control unit 73a performs the second full-open control. After that, the normal opening/closing process ends and the process proceeds to SA1, and the processes from SA1 to SA8 are repeated in the same manner.

Here, "second full-open control" means controlling the first opening/closing control unit 63a so as to maintain the opening/closing state of the opening/closing body 20 in a fully open state.

The specific control content of the second full-open control is arbitrary, but in the embodiment, the second opening/closing control unit 73a sends an activation signal to the first opening/closing control unit 63a, causing the first opening/closing control unit 63a to stop the opening/closing movement of the opening/closing body 20 (specifically, to prevent the opening/closing body 20 from moving to the closed position).

By processing SC2 to SC5 in this manner, when the standby position is set to the fully open position, the opening/closing body 20 can be opened or closed according to the user's usage of the target space 2, thereby improving the usability of the opening/closing control system 40.

In SC6, the opening/closing state determination unit 73b determines whether the opening/closing state of the opening/closing body 20 determined in SC1 is fully closed.

Then, if the open/close state determination unit 73b determines that the door is in a fully closed state (SC6, Yes), it transitions to SC7, and if it determines that the door is not in a fully closed state (SC6, No), it transitions to SC10.

In SC7, the second opening/closing control unit 73a determines whether or not an inside opening/closing operation signal has been received from the inside detection unit 41.

Then, if the second opening/closing control unit 73a determines that it has received an inside opening/closing operation signal (SC7, Yes), it transitions to SC8, and if it determines that it has not received an inside opening/closing operation signal (SC7, No), it transitions to SC9.

In SC8, the second opening/closing control unit 73a performs the first full-open control. After that, the normal opening/closing process ends and the process proceeds to SA1, and the processes from SA1 to SA8 are repeated in the same manner.

Here, "first full-open control" means controlling the first opening/closing control unit 63a so that the opening/closing body 20 is in the fully open position.

The specific control content of the first full-open control is arbitrary, but in the embodiment, the second opening/closing control unit 73a sends an activation signal to the first opening/closing control unit 63a, causing the first opening/closing control unit 63a to move the opening/closing body 20 to the open position.

In SC9, the second opening/closing control unit 73a performs the second full-close control. After that, the normal opening/closing process ends and the process proceeds to SA1, and the processes from SA1 to SA8 are repeated in the same manner.

Here, "second full-close control" means controlling the first opening/closing control unit 63a so as to maintain the opening/closing state of the opening/closing body 20 in a fully closed state.

The specific control content of the second full-close control is arbitrary, but in the embodiment, the second opening/closing control unit 73a does not send an activation signal to the first opening/closing control unit 63a, causing the first opening/closing control unit 63a to stop the opening/closing movement of the opening/closing body 20 (specifically, the opening/closing body 20 is not moved to the open position).

By processing SC6 to SC9 in this way, when the standby position is set to the fully open position, the opening/closing body 20 can be opened or closed according to the user's usage of the target space 2, further improving the usability of the opening/closing control system 40. In addition, by processing SC2 to SC9, the user can smoothly enter and exit the target space 2 using only the inside detection unit 41, reducing the installation costs of the opening/closing control system 40.

At SC10, the second opening/closing control unit 73a performs half-open control (i.e., performs half-open control regardless of the detection result of the inside detection unit 41). After that, the normal opening/closing process ends and the process proceeds to SA1, and the processes from SA1 to SA8 are repeated in the same manner.

Here, "half-open control" means controlling the first opening/closing control unit 63a so as to maintain the opening/closing state of the opening/closing body 20 in a half-open state.

The reason for performing half-open control regardless of the detection result of the inner detection unit 41 is as follows. That is, when performing half-open control based on the detection result of the inner detection unit 41, for example, between the first full-close control (movement of the opening/closing body 20 to close) of SC4 and the fully closed state, the inner detection unit 41 may erroneously detect contact between the inner detection unit 41 and luggage or the like, and perform control to move the opening/closing body 20 to open (so-called reversal control) instead of maintaining the closing movement of the opening/closing body 20. Such control unintended by the user (such as the above-mentioned reversal control) requires the user to take the trouble of performing the inside opening/closing operation, which may reduce the usability of the opening/closing control system 40, and this is to avoid such problems.

The specific control content of the half-open control is optional, but in the embodiment, it is as follows.

In other words, when the opening/closing state of the opening/closing body 20 identified by SC1 is a half-open movement state, the second opening/closing control unit 73a sends an activation signal to the first opening/closing control unit 63a, thereby causing the first opening/closing control unit 63a to continue the opening movement of the opening/closing body 20 (specifically, to continue the first full-open control).

In addition, when the opening/closing state of the opening/closing body 20 identified by SC1 is a half-open/closed movement state, the second opening/closing control unit 73a does not send an activation signal to the first opening/closing control unit 63a, thereby causing the first opening/closing control unit 63a to continue the closing movement of the opening/closing body 20 (specifically, causes the first full-close control to continue).

By processing the SC10 in this manner, when the door is in a half-open state, it is possible to prevent the detection result of the inner detection unit 41 from causing the door to not maintain the half-open state, thereby improving the usability of the opening/closing control system 40.

By performing the above-described opening and closing process, when the return timing and switching timing arrive, normal opening and closing control can be performed after performing learning opening and closing control, and normal opening and closing control can be performed accurately. In addition, using the first control unit 60 and the second control unit 70, learning opening and closing control and normal opening and closing control can be performed accurately, and there is no need to change the control content of the opening and closing control system 40 depending on the standby position of the opening and closing body 20, and the opening and closing movement of the opening and closing body 20 can be controlled using a general-purpose control device as is, thereby reducing the manufacturing cost of the opening and closing control system 40.

(Opening and closing process - specific process contents)
Next, specific processing contents in which the opening and closing processing according to the embodiment is executed will be described below.

(Opening and closing process - specific process content - first specific example)
First, the first specific example will be described.

As a first specific example, when the opening/closing process is started and then the normal opening/closing process of SA8 in FIG. 4 is performed, the process shown below is performed when the user uses the target space 2.

That is, first, before the user enters the target space 2, the fully open state is determined in SC2 in FIG. 6, and since the inside opening/closing operation signal has not been received in SC3 in FIG. 6, the fully open state is maintained by the second fully open control in SC5 in FIG. 6.

Next, after the user enters the target space 2, an inner opening/closing operation is detected by the inner detection unit 41, and when an inner opening/closing operation signal is received in SC3 of FIG. 6, the opening/closing body 20 is moved to the closed position by the first full-close control in SC4 of FIG. 6. After that, if a fully closed state is determined in SC6 of FIG. 6 and an inner opening/closing operation signal has not been received in SC7 of FIG. 6, the fully closed state is maintained by the second full-close control in SC9 of FIG. 6.

Next, just before the user leaves the target space 2, an inner opening/closing operation is detected by the inner detection unit 41, and when an inner opening/closing operation signal is received in SC7 of FIG. 6, the opening/closing body 20 is moved to the open position by the first full-open control in SC8 of FIG. 6. Thereafter, when a fully open state is determined in SC2 of FIG. 6, if an inner opening/closing operation signal has not been received in SC3 of FIG. 6, the fully open state is maintained by the second full-open control in SC5 of FIG. 6. This allows the user to leave the target space 2.

Here, if a power outage occurs while the user is in the target space 2, first, in SA1 of FIG. 4, it is determined that the supply of power from the external power source to the opening/closing control system 40 has been stopped. Next, after the power outage is restored and it is determined that the return timing has arrived in SA2 of FIG. 4, the learning opening/closing process is not executed until the inner detection unit 41 detects the inner opening/closing operation, so that the opening/closing body 20 can be prevented from moving to the open or close position. Then, just before the user leaves the target space 2, when the inner detection unit 41 detects the inner opening/closing operation and it is determined that the opening/closing timing has arrived in SA3, the learning opening/closing process of SA5 of FIG. 4 is executed. Then, after the opening/closing body 20 is moved to the standby position by the adjustment opening/closing control in SA7 of FIG. 4, the normal opening/closing process of SA8 of FIG. 4 is executed. This allows the user to leave the target space 2.

By processing corresponding to this first specific example, when the standby position is set to a position corresponding to the fully open state, the opening/closing body 20 can be opened or closed in accordance with the user's usage of the target space 2. In addition, when the return timing arrives while the user is using the target space 2, it is possible to prevent the opening/closing body 20 from opening or closing against the user's intention.

(Opening and closing process - specific process content - second specific example)
Next, a second specific example will be described.

As a second specific example, after the opening/closing process is started and the normal opening/closing process of SA8 in FIG. 4 is performed, if the manager of the automatic door device 1 (hereinafter referred to as the "manager") performs maintenance work on the target space 2, the following process is performed.

That is, first, before the administrator enters the target space 2, the fully open state is determined in SC2 in FIG. 6, and since the inside opening/closing operation signal has not been received in SC3 in FIG. 6, the fully open state is maintained by the second fully open control in SC5 in FIG. 6.

Next, after the manager enters the target space 2, the inside detection unit 41 detects an inside opening/closing operation, and when an inside opening/closing operation signal is received in SC3 of FIG. 6, the opening/closing body 20 is moved to the closed position by the first full-close control in SC4 of FIG. 6. Next, if a fully closed state is determined in SC6 of FIG. 6 and an inside opening/closing operation signal is not received in SC7 of FIG. 6, the fully closed state is maintained by the second full-close control in SC9 of FIG. 6. After that, when the switching unit 44 switches the power supply state from a continuous state to a cut-off state by operation of the manager, the manager performs maintenance work.

Next, after the maintenance work is completed, the manager operates the switching unit 44 to switch the power supply state from a cut-off state to a continuous state, and when it is determined that the switching timing has arrived in SA4 of FIG. 4, the learning opening/closing process in SA5 of FIG. 4 is executed regardless of the detection result of the inside detection unit 41. Then, after the opening/closing body 20 is moved to the standby position by the adjusted opening/closing control in SA7 of FIG. 4, the normal opening/closing process in SA8 of FIG. 4 is executed. This allows the manager to leave the target space 2.

By processing the second specific example, when the switching timing arrives while the administrator is using the target space 2, the learning opening/closing process can be performed more quickly than when the return timing arrives.

(Effects of the embodiment)
Thus, according to the embodiment, there is provided a detection means for detecting that the opening/closing timing has arrived to start the opening/closing movement of the opening/closing body 20, an opening/closing state identification unit 73b for identifying the opening/closing state of the opening/closing body 20, a first opening/closing control unit 63a for controlling the opening/closing movement of the opening/closing body 20, and a second opening/closing control unit 73a configured separately from the first opening/closing control unit 63a and controlling the first opening/closing control unit 63a based on the detection result of the detection means and the identification result of the opening/closing state identification unit 73b. Therefore, there is no need to change the control content of the opening/closing control system 1 according to the waiting position of the opening/closing body 20, and the opening/closing movement of the opening/closing body 20 can be controlled by using a general-purpose control device as is, thereby reducing the manufacturing cost of the opening/closing control system 1.

In addition, after the second opening/closing control unit 73a has positioned the opening/closing body 20 to the standby position, if the fully open state is identified by the opening/closing state identification unit 73b and an inner opening/closing operation is not detected by the inner detection unit 41, the second opening/closing control unit 73a controls the first opening/closing control unit 63a to maintain the opening/closing state of the opening/closing body 20 in the fully open state, and if the fully open state is identified by the opening/closing state identification unit 73b and an inner opening/closing operation is detected by the inner detection unit 41, the first opening/closing control unit 63a controls the opening/closing state of the opening/closing body 20 to be in the fully closed state in which the opening/closing target area is fully closed by the opening/closing body 20. Therefore, when the standby position is set to the fully open position, the opening/closing movement of the opening/closing body 20 can be performed according to the usage status of the target space 2 by the user, and the usability of the opening/closing control system 1 can be improved.

In addition, after the second opening/closing control unit 73a positions the opening/closing body 20 to the standby position, if the fully closed state is identified by the opening/closing state identification unit 73b and the inside detection unit 41 does not detect an inside opening/closing operation, the first opening/closing control unit 63a is controlled to maintain the opening/closing state of the opening/closing body 20 in the fully closed state, and if the fully closed state is identified by the opening/closing state identification unit 73b and the inside detection unit 41 detects an inside opening/closing operation, the first opening/closing control unit 63a is controlled to set the opening/closing state of the opening/closing body 20 to the fully open state. Therefore, when the standby position is set to the fully open position, the opening/closing body 20 can be opened/closed according to the user's use of the target space 2, and the usability of the opening/closing control system 1 can be further improved. In addition, the user can smoothly enter and exit the target space 2 using only the inside detection unit 41, and the installation cost of the opening/closing control system 1 can be reduced.

In addition, when the second opening/closing control unit 73a positions the opening/closing body 20 to the standby position and the opening/closing state determination unit 73b determines a half-open state, which is a state between the fully closed state and the fully closed state, the first opening/closing control unit 63a is controlled to maintain the opening/closing state of the opening/closing body 20 in the half-open state regardless of the detection result of the inner detection unit 41. This makes it possible to avoid the half-open state being no longer maintained due to the detection result of the inner detection unit 41 when the opening/closing body 20 is in the half-open state, thereby improving the usability of the opening/closing control system 1.

[III] Modifications to the embodiments The embodiments of the present invention have been described above, but the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of each invention described in the claims. Such modifications will be described below.

(About the problem to be solved and the effects of the invention)
First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and the present invention may solve problems that are not described above or achieve effects that are not described above, or may solve only some of the problems that are described or achieve only some of the effects that are described.

(Regarding decentralization and integration)
In addition, each of the electrical components described above is a functional concept, and does not necessarily have to be physically configured as shown in the figure. In other words, the specific form of distribution or integration of each part is not limited to that shown in the figure, and all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. For example, the second control unit 70 may be distributed to multiple devices configured to be able to communicate with each other, and the second control unit 73 may be provided in some of the multiple devices, and the second storage unit 74 may be provided in another part of the multiple devices.

(shape, number, structure, time series)
The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention with respect to the shape, numerical values, or structure or chronological relationships of multiple components.

(About automatic door systems)
In the above embodiment, the automatic door system 1 is described as including the lock unit 32 and the output unit 33, but this is not limited thereto, and for example, at least one of the lock unit 32 and the output unit 33 may be omitted.

(Opening and closing control system)
In the above embodiment, the opening and closing control system 40 has been described as including the switching unit 44, but this is not limiting, and for example, the switching unit 44 may be omitted. In this case, the process of SA4 of the opening and closing process may be omitted, and when it is determined in SA1 that the supply of power from the external power source to the opening and closing control system 40 has not been stopped, the normal opening and closing process (SA8) may be started.

(Detection means)
In the above embodiment, the detection means is described as including the inside detection unit 41, but is not limited thereto. For example, when the target space 2 is a conference room or the like, in addition to the inside detection unit 41, another different detection means (as an example, an outside detection means for detecting an outside opening/closing operation) may be further provided. Note that the "outside opening/closing operation" refers to an operation performed by a user present outside the target space 2, and is an operation that serves as a trigger for starting the opening/closing operation of the opening/closing body 20.

In addition, in the above embodiment, the inner detection unit 41 is described as a transmission type photoelectric sensor, but it is not limited to this and may be a quantum type infrared sensor or a push button switch.

(Regarding the control device)
In the above embodiment, the control device 50 is described as including the first control unit 60 and the second control unit 70 that are configured separately, but this is not limited thereto. For example, a single control unit having the functions of the first control unit 60 and the second control unit 70 may be provided (i.e., the first opening/closing control means and the second opening/closing control means may be integrated into a single opening/closing control means). In this case, it is desirable to change the control content of the opening/closing control system 40 depending on the standby position of the opening/closing body 20.

In addition, in the above embodiment, the first control unit 60 is described as being configured as a general-purpose control device with normally closed specifications, but this is not limited to the above. For example, if the target space 2 is a special workroom or the like, it may be configured as a general-purpose control device with normally open specifications. In this case, the activation signal may be a signal indicating an instruction to move the opening/closing body 20 to the closing position, the standby position may be set to the fully closed position, and the above-mentioned outer detection means may be provided instead of the inner detection unit 41.

(Regarding the second control unit)
In the above embodiment, the second control unit 73 is described as including the open/close state specification unit 73b, but this is not limiting, and for example, the open/close state specification unit 73b may be omitted. In this case, the inside detection unit 41 may include a first inside detection unit that detects an inside opening operation that is a trigger for starting an opening operation of the opening/closing body 20, and a second inside detection unit that detects an inside closing operation that is a trigger for starting a closing operation of the opening/closing body 20. In addition, in the normal opening/closing process, the second opening/closing control unit 73a may control the first opening/closing control unit 63a based on the detection results of the first inside detection unit and the second inside detection unit (i.e., based only on the detection results of the detection means).

As an example, in the normal opening and closing process, the second opening and closing control unit 73a may control the first opening and closing control unit 63a to maintain the opening and closing state of the opening and closing body 20 in a fully open state when the first inside detection unit has not detected an inward opening operation and the second inside detection unit has not detected an inward closing operation after the learning opening and closing control unit 73a has performed the opening and closing body 20 to the standby position. Next, when the second inside detection unit detects an inward closing operation, the first opening and closing control unit 63a may be controlled to maintain the opening and closing state of the opening and closing body 20 in a fully closed state, and the first opening and closing control unit 63a may be controlled to maintain the opening and closing state of the opening and closing body 20 in a fully closed state until the first inside detection unit detects an inward opening operation. Next, when the first inside detection unit detects an inward opening operation, the first opening and closing control unit 63a may be controlled to maintain the opening and closing state of the opening and closing body 20 in a fully open state, and the first opening and closing control unit 63a may be controlled to maintain the opening and closing state of the opening and closing body 20 in a fully open state until the first inside detection unit detects an inward closing operation.

(About opening and closing process)
In the above embodiment, the processes of SA1 and SA2 are described as being performed separately, but the present invention is not limited to this, and for example, the processes of SA1 and SA2 may be performed together. As an example, it may be determined whether or not the restoration timing has arrived after the power supply has been stopped in the opening/closing process while referring to the operation history information stored in the second storage unit 74. Specifically, it may be determined based on whether or not the amount of power supply from the external power source has become equal to or greater than the threshold value when the power supply from the external power source is resumed after the amount of power supply from the external power source has become less than the threshold value in the opening/closing process.

In the above embodiment, the process of SA7 is described as being performed, but this is not limiting, and for example, the process of SA7 may be omitted. In this case, if it is determined in SA6 that the position of the opening/closing body 20 is not the standby position, the opening/closing body 20 may be manually moved by an administrator or the like to open or close so that the opening/closing body 20 is in the standby position.

In the above embodiment, when it is determined that the switching timing has arrived in SA4, the learning opening/closing process (SA5) is started regardless of the detection result of the inside detection unit 41. However, this is not limited to the above. For example, when it is determined that the switching timing has arrived in SA4, the learning opening/closing process (SA5) may be started when the inside detection unit 41 detects that the opening/closing timing has arrived.

(About learning opening and closing process)
In the above embodiment, the opening/closing body 20 is opened to the fully open position to identify the fully open position, and then the opening/closing body 20 is closed to the fully closed position to identify the fully closed position, but this is not limited to the above. For example, the opening/closing body 20 may be opened to the fully closed position to identify the fully closed position, and then the opening/closing body 20 may be closed to the fully open position to identify the fully open position.

(Additional Note)
The opening/closing control system of Appendix 1 is an opening/closing body that constitutes an automatic door device installed in a target space, and is an opening/closing control system for controlling the opening/closing movement of the opening/closing body that opens and closes a target opening/closing area in the target space, and is equipped with a detection means for detecting the arrival of an opening/closing timing to start the opening/closing movement of the opening/closing body, an opening/closing state identification means for identifying the opening/closing state of the opening/closing body, a first opening/closing control means for controlling the opening/closing movement of the opening/closing body, and a second opening/closing control means configured separately from the first opening/closing control means, and which controls the first opening/closing control means based on the detection result of the detection means and the identification result of the opening/closing state identification means.

The opening/closing control system of Supplementary Note 2 is the opening/closing control system described in Supplementary Note 1, in which the detection means includes an inside detection means for detecting an inside opening/closing action performed by a user present inside the target space, which is a trigger for starting the opening/closing action of the opening/closing body, and the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully open state if the inside opening/closing action is not detected by the inside detection means when the fully open state is specified by the opening/closing state specification means after the opening/closing body is positioned to a standby position that corresponds to a fully open state in which the opening/closing target area is fully opened by the opening/closing body and is a position for waiting for the opening/closing movement of the opening/closing body, and controls the first opening/closing control means to change the opening/closing state of the opening/closing body to a fully closed state in which the opening/closing target area is fully closed by the opening/closing body when the inside detection means detects the inside opening/closing action when the fully open state is specified by the opening/closing state specification means.

The opening/closing control system of Supplementary Note 3 is the opening/closing control system described in Supplementary Note 2, in which the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully closed state if the fully closed state is identified by the opening/closing state identification means and the inner opening/closing operation is not detected by the inner detection means after the opening/closing body is positioned to the standby position, and controls the first opening/closing control means to change the opening/closing state of the opening/closing body to the fully open state if the inner detection means detects the inner opening/closing operation when the fully closed state is identified by the opening/closing state identification means.

The opening/closing control system of Supplementary Note 4 is the opening/closing control system described in Supplementary Note 2 or 3, in which, after the opening/closing body is positioned to the standby position, when the opening/closing state identification means identifies a half-open state that is a state between the fully closed state and the fully closed state, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the half-open state regardless of the detection result of the inside detection means.

(Effect of supplementary notes)
According to the opening/closing control system described in Appendix 1, the system is equipped with a detection means for detecting that the opening/closing timing for starting the opening/closing movement of the opening/closing body has arrived, an opening/closing state identification means for identifying the opening/closing state of the opening/closing body, a first opening/closing control means for controlling the opening/closing movement of the opening/closing body, and a second opening/closing control means configured separately from the first opening/closing control means and for controlling the first opening/closing control means based on the detection result of the detection means and the identification result of the opening/closing state identification means, so there is no need to change the control content of the opening/closing control system according to the waiting position of the opening/closing body, and the opening/closing movement of the opening/closing body can be controlled by using a general-purpose control device as is, thereby reducing the manufacturing costs of the opening/closing control system.

According to the opening/closing control system described in Appendix 2, after the second opening/closing control means has positioned the opening/closing body to the standby position, if the fully open state is identified by the opening/closing state identification means and no inner opening/closing operation is detected by the inner detection means, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully open state, and if the fully open state is identified by the opening/closing state identification means and an inner opening/closing operation is detected by the inner detection means, the first opening/closing control means controls the opening/closing state of the opening/closing body to be in the fully closed state in which the opening/closing target area is fully closed by the opening/closing body. Therefore, when the standby position is set to the fully open position, the opening/closing movement of the opening/closing body can be performed according to the user's usage of the target space, and the usability of the opening/closing control system can be improved.

According to the opening/closing control system described in Appendix 3, after the second opening/closing control means has positioned the opening/closing body to the standby position, if the fully closed state is identified by the opening/closing state identification means and no inner opening/closing operation is detected by the inner detection means, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the fully closed state, and if the fully closed state is identified by the opening/closing state identification means and an inner opening/closing operation is detected by the inner detection means, the first opening/closing control means controls the opening/closing state of the opening/closing body to be in the fully open state. Therefore, when the standby position is set to the fully open position, the opening/closing body can be opened/closed according to the usage status of the target space by the user, and the usability of the opening/closing control system can be further improved. In addition, the user can smoothly enter and exit the target space using only the inner detection means, and the installation cost of the opening/closing control system can be reduced.

According to the opening/closing control system described in Appendix 4, when the opening/closing state determination means has determined that the opening/closing body is in a half-open state between the fully closed and fully closed states after the second opening/closing control means has positioned the opening/closing body to the standby position, the second opening/closing control means controls the first opening/closing control means to maintain the opening/closing state of the opening/closing body in the half-open state regardless of the detection result of the inner detection means. This makes it possible to avoid the half-open state being discontinued due to the detection result of the inner detection means when the opening/closing body is in the half-open state, thereby improving the usability of the opening/closing control system.
