Description

The present invention relates to a control system.

Conventionally, technology has been proposed for contactless operation of opening and closing the opening/closing body from the perspective of infection control, targeting shutter devices attached to openings of buildings. In such technology, for example, a technology is disclosed in which the opening/closing body is opened/closed or the opening/closing movement is stopped based on the detection state of whether or not an area sensor installed on the periphery of the opening detects the approach of a finger (see, for example, Patent Document 1). In addition, the above-mentioned area sensor includes a first area sensor corresponding to the open button, a second area sensor corresponding to the stop button, and a third area sensor corresponding to the close button, and each of these area sensors is composed of a near-infrared distance-limited reflective area sensor that transmits a detection signal when it detects the approach of a finger.

JP 2017-95940 A

In the above conventional technology, as described above, the first area sensor, the second area sensor, and the third area sensor are configured as near-infrared distance-limited reflection area sensors, but details of the setting of the time required from the detection of the approach of a finger in each area sensor to the transmission of a detection signal are not disclosed. For this reason, for example, when the above-mentioned times of each area sensor are set to be the same and relatively long, if the closing movement of the opening/closing body is stopped using the third area sensor, there is a risk that the stopping will take time and the opening/closing body will come into contact with a person or object passing through the opening. Therefore, there is room for improvement from the perspective of increasing safety when using an opening/closing device such as a shutter device.

The present invention is intended to solve the problems in the conventional technology described above, and aims to provide a control system that can improve safety when using opening and closing devices.

The first signal is transmitted a predetermined time after the transmission of the first signal, and the response time from when an operation is performed at the one non-contact sensor to when the first signal is transmitted after the input of the operation is accepted is set to be the same as the stop response time, and when the opening/closing movement control means is moving the opening/closing body to open or close, it identifies the first signal received from the one non-contact sensor as the stop signal and ignores the second signal received from the one non-contact sensor, and when the opening or closing movement of the opening/closing body is stopped, it ignores the first signal received from the one non-contact sensor and identifies the second signal received from the one non-contact sensor as the open signal or the close signal.

According to the control system described in claim 1, the stop response time is made shorter than the open response time and shorter than the close response time, so that the opening or closing movement of the opening/closing body can be stopped quickly while suppressing malfunction of the opening or closing movement of the opening/closing body, compared to when the opening response time, closing response time, and stop response time are the same, thereby improving safety when using the opening/closing device.
In addition, the opening operation means is configured with a non-contact sensor that transmits an opening signal in an identifiable manner, the closing operation means is configured with a non-contact sensor that is separate from the opening operation means and transmits a closing signal in an identifiable manner, and the stop operation means is configured with a non-contact sensor or push button that is separate from the opening operation means and the closing operation means and transmits a stop signal in an identifiable manner, so that the opening operation input , the closing operation input , and the stop operation input can be made individually using separate non-contact sensors (or push buttons), thereby improving the usability of the opening operation means, the closing operation means, and the stop operation means.

According to the control system described in claim 3, the stop response time is made shorter than the open response time and shorter than the close response time, so that the opening or closing movement of the opening/closing body can be stopped quickly while suppressing malfunction of the opening or closing movement of the opening/closing body, compared to when the opening response time, closing response time, and stop response time are the same, thereby improving safety when using the opening/closing device.
In addition, since the opening operation means, closing operation means, and stopping operation means are integrated into a single non-contact sensor, the number of parts and the manufacturing effort required for the opening operation means, closing operation means, and stopping operation means can be reduced, and the manufacturability of the opening operation means, closing operation means, and stopping operation means can be improved.
In addition, the opening/closing movement control means identifies an indistinguishable signal received from one non-contact sensor as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, and controls the opening/closing movement of the opening/closing body based on the identified open signal, close signal, or stop signal.Therefore, when one non-contact sensor transmits an open signal, a close signal, or a stop signal as an indistinguishable signal, the indistinguishable signal can be identified as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, making it possible to accurately control the opening/closing movement of the opening/closing body.
In addition, when an opening/closing movement in progress signal is received from the opening/closing movement control means, the response time from when an operation is performed at one non-contact sensor to when an unidentifiable signal is transmitted after the operation input is accepted is set to be the same as the stop response time, and when the opening/closing movement control means is moving the opening/closing body to open or close, the unidentifiable signal received from one non-contact sensor is identified as a stop signal.Therefore, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as an unidentifiable signal, the opening or closing movement of the opening/closing body can be quickly stopped, making it easier to ensure safety when using the opening/closing device.

According to the control system described in claim 4, the stop response time is made shorter than the open response time and shorter than the close response time, so that the opening or closing movement of the opening/closing body can be stopped quickly while suppressing malfunction of the opening or closing movement of the opening/closing body, compared to when the opening response time, closing response time, and stop response time are the same, thereby improving safety when using the opening/closing device.
In addition, since the opening operation means, closing operation means, and stopping operation means are integrated into a single non-contact sensor, the number of parts and the manufacturing effort required for the opening operation means, closing operation means, and stopping operation means can be reduced, and the manufacturability of the opening operation means, closing operation means, and stopping operation means can be improved.
In addition, the opening/closing movement control means identifies an indistinguishable signal received from one non-contact sensor as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, and controls the opening/closing movement of the opening/closing body based on the identified open signal, close signal, or stop signal.Therefore, when one non-contact sensor transmits an open signal, a close signal, or a stop signal as an indistinguishable signal, the indistinguishable signal can be identified as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, making it possible to accurately control the opening/closing movement of the opening/closing body.
In addition, the response time from when an operation is performed at one non-contact sensor to when the first signal is transmitted after the input of the operation is accepted is set to the same as the stop response time, and when the opening/closing movement control means is moving the opening/closing body to open or close, it identifies the first signal received from one non-contact sensor as a stop signal and ignores the second signal received from one non-contact sensor, and when it is stopping the opening or closing movement of the opening/closing body, it ignores the first signal received from one non-contact sensor and identifies the second signal received from one non-contact sensor as an open signal or a close signal.Therefore, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as the first signal and the second signal, the opening or closing movement of the opening/closing body can be quickly stopped, making it easier to ensure safety when using the opening/closing device.

The following describes in detail an embodiment of a control system according to the present invention with reference to the accompanying drawings. 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, a basic concept of the embodiment will be described. The embodiment generally relates to a control system for controlling an opening and closing device having an opening and closing body that opens and closes an opening in a building.

Here, the term "building" refers to any specific structure or type, but is a concept that includes, for example, a detached house, an apartment or condominium complex, an office building, a commercial facility, and a public facility. An "opening in a building" is an opening formed in a part of the building's structure (e.g., a wall, floor, ceiling, etc.) for installing an entrance or window. An opening and closing device is a device that is attached to an opening in a building for crime prevention or fire prevention, and is a concept that includes all types of shutter devices and door devices that can be electrically driven, such as heavy shutters. The opening and closing directions of an opening and closing device include, for example, the up-down direction, the left-right direction, the front-rear direction, etc.

The "open/closed state of the opening/closing body" is a concept that includes, for example, the "fully closed state," the "fully open state," and the "half-open state."

Of these, the "fully closed state" is a state in which the opening 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." Additionally, the "fully open state" is a state in which the opening 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." Additionally, the "half-open state" is a state in which the opening/closing body is located between the fully closed position and the fully open position, and the position of the opening/closing body in the half-open state is referred to as the "half-open position."

The "movement state of the opening/closing body" is a concept that includes, for example, the "open movement state," the "closed movement state," and the "stopped state."

Of these, the "open movement state" is a state in which the opening/closing body is moving in an open direction. The "close movement state" is a state in which the opening/closing body is moving in a closed direction. The "stop state" is a state in which the opening/closing movement of the opening/closing body is stopped.

In the following embodiment, we will explain the case where the opening and closing device is an electric shutter that opens and closes from above and below, installed at the entrance and exit of a garage in a building such as an apartment building.

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

[First embodiment]
First, a description will be given of a control system according to embodiment 1. In this embodiment 1, an opening operation unit, a closing operation unit, and a stopping operation unit, which will be described later, are configured separately.

(composition)
First, the configuration of a switching device to which the control system according to the first embodiment is applied will be described.

In the following description, the X direction in FIG. 1 is referred to as the left-right direction of the opening/closing device (-X direction is the left direction of the opening/closing device, and +X direction is the right direction of the opening/closing device), the Y direction in FIG. 1 is referred to as the up-down direction of the opening/closing device (+Y direction is the up direction of the opening/closing device, and -Y direction is the down direction of the opening/closing device), and the direction perpendicular to the X and Y directions is referred to as the front-to-back direction (the direction leading to the front side of the paper in FIG. 1 is the front direction of the opening/closing device (toward the outside of the building), and the direction leading to the back side of the paper in FIG. 1 is the rear direction of the opening/closing device (toward the inside of the building)).

As shown in FIG. 1, the opening/closing device 1 generally includes a storage section 10, a guide rail 20, an opening/closing body 30, an opening/closing machine 40, a winding shaft (not shown), and a control system 50. However, unless otherwise specified, the configuration of the opening/closing device 1 is the same as that of the conventional device and will not be described here.

The connection form of each component constituting this opening/closing device 1 is set as shown below. That is, the control device 90 of the control system 50 described later is electrically connected to the opening/closing machine 40, the operation device 60 of the control system 50 described later, the upper limit detection unit 71, the lower limit detection unit 72, and the seat board switch 81 via wiring 3. This allows communication or power supply directly or indirectly between the control device 90 described later and the opening/closing machine 40, the operation device 60 described later, the upper limit detection unit 71 described later, the lower limit detection unit 72 described later, or the seat board switch 81 described later.

The method of mounting (or connecting) the various members constituting the opening and closing device 1 is arbitrary, but for example, a method of mounting (or connecting) the mounting side member to the mounting counterpart member using fasteners (e.g., rivets, mounting screws, screws, etc.), welding, adhesives, double-sided tape, etc., through mounting holes (e.g., rivet holes, screw holes, screw holes, etc.) formed in the mounting side member or the mounting counterpart member is used.

(Configuration - Storage section)
The storage section 10 is a hollow body for storing each part of the opening/closing device 1. As shown in Fig. 1, the storage section 10 is installed above the upper end of the opening 2 in the wall of the building. The storage section 10 also stores the opening/closing machine 40, the winding shaft, and an upper limit detection section 71, a lower limit detection section 72, a cord reel 82, and a control device 90 of the control system 50 described later, and when the opening/closing body 30 is wound up by the winding shaft, at least a part of the opening/closing body 30 is also stored inside the storage section 10.

(Configuration - Guide Rail)
The guide rail 20 guides the opening/closing body 30 to move along the opening/closing direction (vertical direction) of the opening 2. The guide rail 20 is an elongated body formed so that its cross section is substantially U-shaped, and is disposed at each of the left and right ends of the opening/closing device 1 in a direction substantially along the vertical direction, and is directly fixed to the wall of the building or indirectly fixed via a base material (not shown).

(Configuration - Opening and closing body)
The opening/closing body 30 is a shielding means that is moved to close or open by the winding shaft, thereby changing the state of the opening/closing body 30 to a fully open state, a fully closed state, or a half-open state. As shown in Fig. 1, the opening/closing body 30 is configured with a plurality of slats 31, and the plurality of slats 31 are fitted and connected to each other via fitting parts (not shown) formed at both upper and lower ends of each slat 31. Each of the left and right ends of the opening/closing body 30 is inserted into the inside of the guide rail 20 via the U-shaped open end of the guide rail 20, and is slidable inside the guide rail 20 in the up and down direction, and is restricted from falling out of the guide rail 20 in the front and rear direction.

A seat plate 32 is connected to the closed end of the opening/closing body 30 (specifically, the lower end of the opening/closing body 30). This seat plate 32 is arranged so as to be close to or in contact with the floor surface of the building in the fully closed state, and is formed over the entire length of the closed end of the opening/closing body 30 in the left-right direction.

(Configuration - Switching Machine)
The opening/closing machine 40 is a driving means for electrically moving the opening/closing body 30 to open and close by controlling the rotation of the winding shaft. As shown in Fig. 1, the opening/closing machine 40 is provided in the storage unit 10 in a position adjacent to the winding shaft, and is configured by, for example, a known opening/closing machine. Specifically, the opening/closing machine 40 includes an output shaft that transmits the rotational force transmitted from the drive unit to the winding shaft, a drive unit that drives the opening/closing body 30 by electrically rotating the output shaft, and a brake unit that acts on the output shaft to brake the rotation of the winding shaft (all of which are not shown).

(Configuration - Winding shaft)
The winding shaft is a rotating shaft for moving the opening/closing body 30 to close or open. This winding shaft is configured, for example, using a known winding shaft or the like, and is installed along the left-right direction. In addition, a connecting slat (not shown) connected to the upper end of the opening/closing body 30 is connected to this winding shaft, and by rotating this winding shaft, the opening/closing body 30 can be moved to close or open via the connecting slat. In addition, since the left end (or right end) of this winding shaft is connected to the output shaft of the opening/closing machine 40 via a chain (not shown) and a clutch (not shown), the winding shaft can be rotated in conjunction with the rotation of the output shaft of the opening/closing machine 40.

(Configuration - Control System)
Next, the configuration of the control system 50 will be described.

The control system 50 is for controlling the opening and closing device 1, and includes an operating device 60, an upper limit detection unit 71, a lower limit detection unit 72, a seat switch 81, a cord reel 82, and a control device 90, as shown in FIG. 1.

(Configuration - Control System - Operation Device)
The operating device 60 is an operating means for performing operations related to the opening/closing device 1. As shown in Fig. 1, the operating device 60 is provided near the opening 2 and is configured using, for example, a known operating device for a shutter device, and includes an opening operation unit 61, a closing operation unit 62, and a stopping operation unit 63.

(Configuration-Control system-Operation device-Opening operation unit)
The opening operation unit 61 is an opening operation means that transmits an opening signal corresponding to the opening operation input when it receives a non-contact input of an opening operation for moving the opening/closing body 30 to open. In the first embodiment, the opening operation unit 61 is configured with a non-contact sensor that transmits an opening signal in an identifiable manner, and may be configured with, for example, an infrared contact sensor, a microwave contact sensor, or a transmission type photoelectric sensor.

Here, "transmitting an open signal in an identifiable manner" refers to, for example, transmitting an open signal with a specific identification code indicating that it is an open signal (note that the same applies to the case of transmitting a close signal or a stop signal in an identifiable manner).

(Configuration-Control system-Operation device-Closing operation unit)
The closing operation unit 62 is a closing operation means that transmits a closing signal corresponding to the input of the closing operation when it receives a non-contact input of a closing operation for moving the opening/closing body 30 to close. In the first embodiment, the closing operation unit 62 is separate from the opening operation unit 61 and is configured with a non-contact sensor (e.g., an infrared contact sensor or the like) that transmits a closing signal in an identifiable manner, and is provided at a distance from the opening operation unit 61.

(Configuration-Control system-Operation device-Stop operation unit)
The stop operation unit 63 is a stop operation means that transmits a stop signal corresponding to the input of the stop operation when it receives, by contact or non-contact, a stop operation input for stopping the opening movement or closing movement of the opening/closing body 30. In the first embodiment, the stop operation unit 63 is separate from the opening operation unit 61 and the closing operation unit 62, and is configured with a non-contact sensor (e.g., an infrared contact sensor or the like) that transmits a stop signal in an identifiable manner, and is provided at a distance from the opening operation unit 61 and the closing operation unit 62. However, the present invention is not limited to this, and may be configured with, for example, a push button that transmits a stop signal in an identifiable manner.

In addition, the setting method for transmitting various signals in the opening operation unit 61, the closing operation unit 62, and the stop operation unit 63 is arbitrary, but in embodiment 1, the response time from when a stop operation is performed in the stop operation unit 63 to when a stop signal is transmitted after the input of the stop operation is accepted (hereinafter referred to as the ``stop response time'') is set to be shorter than the response time from when an opening operation is performed in the opening operation unit 61 to when an opening signal is transmitted after the input of the opening operation is accepted (hereinafter referred to as the ``open response time''), and shorter than the response time from when a closing operation is performed in the closing operation unit 62 to when a closing signal is transmitted after the input of the closing operation is accepted (hereinafter referred to as the ``close response time'').

Specifically, the stop response time from the time the stop operation is performed until the input of the stop operation is accepted (specifically, the time during which the input of the stop operation is continuously being made; hereinafter referred to as the "stop acceptance time") is set to be shorter than the open response time from the time the open operation is performed until the input of the open operation is accepted (specifically, the time during which the input of the open operation is continuously being made; hereinafter referred to as the "open acceptance time"), and is set to be shorter than the close response time from the time the close operation is performed until the input of the close operation is accepted (specifically, the time during which the input of the close operation is continuously being made; hereinafter referred to as the "close acceptance time").

In addition, the time within the stop response time from when the input of the stop operation is accepted to when the stop signal is sent (hereinafter referred to as the "stop transmission time") is set to be the same as the time within the open response time from when the input of the open operation is accepted to when the open signal is sent (hereinafter referred to as the "open transmission time"), and is also set to be the same as the time within the close response time from when the input of the close operation is accepted to when the close signal is sent (hereinafter referred to as the "close transmission time").

In the first embodiment, the opening response time and the closing response time are set to be the same, but this is not limited thereto, and for example, they may be set to be unequal.

For example, if the opening response time = closing response time = 1.0 sec, the stopping response time may be set to 0.05 sec.

By setting it in this way, compared to when the opening response time, closing response time, and stop response time are the same, it is possible to quickly stop the opening or closing movement of the opening/closing body 30 while suppressing malfunction of the opening or closing movement of the opening/closing body 30, thereby improving safety when using the opening/closing device 1.

In the first embodiment, the operation device 60 is described as communicating with the control device 90 via a wired connection, but this is not limited thereto, and for example, the operation device 60 may communicate with the control device 90 wirelessly. In addition, both a wired type and a wireless type operation device 60 may be provided.

With the operating device 60 as described above, the input of the opening operation , the input of the closing operation , and the input of the stopping operation can be performed individually using separate non-contact sensors (or push buttons), thereby improving the usability of the opening operation unit 61, the closing operation unit 62, and the stopping operation unit 63.

(Configuration - Control System - Upper Limit Detection Unit)
The upper limit detection unit 71 is an upper limit detection means that detects whether the closing side end of the opening/closing body 30 has reached the fully open position. This upper limit detection unit 71 is configured using, for example, a known detection sensor (one example is a counter-type limit switch that detects the number of rotations of the output shaft of the opening/closing machine 40, etc.), and is installed in a position near the opening/closing machine 40 inside the storage unit 10 as shown in FIG.

In addition, when the upper limit detection unit 71 is the above-mentioned counter-type limit switch, the specific detection operation is arbitrary, but for example, when the number of rotations of the output shaft of the opening/closing device 40 reaches the required number of rotations required for the closing side end of the opening/closing body 30 to reach the fully open position from the lower end of the opening 2, an upper limit detection signal indicating this is output. On the other hand, when the number of rotations of the output shaft of the opening/closing device 40 does not reach the above-mentioned required number of rotations, an upper limit detection signal is not output.

(Configuration - Control System - Lower Limit Detection Unit)
The lower limit detection unit 72 is a lower limit detection means that detects whether the closing side end of the opening/closing body 30 has reached the fully closed position. This lower limit detection unit 72 is configured using, for example, a known detection sensor (one example is a counter-type limit switch that detects the number of rotations of the output shaft of the opening/closing machine 40, etc.), and is installed in a position near the opening/closing machine 40 inside the storage unit 10 as shown in FIG.

In addition, when the lower limit detection unit 72 is the above-mentioned counter-type limit switch, the specific detection operation is arbitrary, but for example, when the rotation speed of the output shaft of the opening/closing device 40 reaches the required rotation speed required for the closing side end of the opening/closing body 30 to reach the fully closed position from the upper end of the opening 2, a lower limit detection signal indicating this is output. On the other hand, when the rotation speed of the output shaft of the opening/closing device 40 does not reach the above-mentioned required rotation speed, the lower limit detection signal is not output.

(Configuration - Control System - Seat Switch)
The seat switch 81 is an obstacle detection unit that detects an obstacle. Here, an "obstacle" means something that hinders the opening/closing movement (specifically, the closing movement) of the opening/closing body 30, and corresponds to, for example, a person, an animal, an object, etc.

This seat switch 81 is configured, for example, using a known wired seat switch (such as a microswitch), and is attached to the seat 32 as shown in FIG. 1.

In addition, when the seat switch 81 is a microswitch, the detection operation is optional, but for example, if the closing end of the opening/closing body 30 comes into contact with an obstacle and is lifted upward relative to the opening/closing body 30 during the closing movement of the opening/closing body 30, the lifted displacement is detected by a microswitch or the like, and a signal including information indicating that an obstacle has been detected (hereinafter referred to as an "obstacle detection signal") is output. On the other hand, if the closing end of the opening/closing body 30 does not come into contact with an obstacle and is not lifted upward relative to the opening/closing body 30 during the closing movement of the opening/closing body 30, no obstacle detection signal is output.

In the first embodiment, the seat switch 81 is described as being provided, but the present invention is not limited to this. For example, any detection means for detecting an obstacle can be used instead of the seat switch 81. As an example, an obstacle present below the closed end of the opening/closing body 30 can be detected by a photoelectric sensor or the like.

(Configuration - Control System - Cord Reel)
The cord reel 82 winds up or unwinds the seat board side wiring 4 so that the unwound length of the wiring 4 (hereinafter referred to as "seat board side wiring 4") connecting the seat board switch 81 and the control device 90 so as to be capable of wired communication is always maintained at an appropriate length even if the seat board switch 81 moves in the opening/closing movement direction as the opening/closing device 1 opens or closes. The cord reel 82 is configured using, for example, a known cord reel, and is provided near the opening 2 as shown in FIG.

(Configuration-Control System-Control Device)
The control device 90 is a device that links each part of the opening and closing device 1 with each other, and includes a communication part 91, a power supply part 92, a control part 93, and a storage part 94, as shown in FIG.

(Configuration-Control Device-Communication Unit)
The communication unit 91 is a communication means for communicating between the opening/closing device 40 , the operating device 60 , the upper limit detection unit 71 , the lower limit detection unit 72 , or the seat switch 81 and the control device 90 .

(Configuration - Control Device - Power Supply Section)
The power supply unit 92 is a power supply means that supplies power from a commercial power source or a battery (e.g., a battery, etc.) not shown in the figure to each part of the control device 90, and also supplies power to the operating device 60, the upper limit detection unit 71, the lower limit detection unit 72, the seat switch 81, etc.

(Configuration-Control Device-Control Unit)
The control unit 93 is a control means for controlling each unit of the control device 90. Specifically, the control unit 93 is a computer including a CPU, various programs 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.

Furthermore, as shown in FIG. 2, the control unit 93 is functionally and conceptually equipped with an opening/closing movement control unit 93a.

(Configuration-Control device-Control unit-Opening/closing movement control unit)
The opening/closing movement control unit 93a is an opening/closing movement control means that controls the opening/closing movement of the opening/closing body 30 based on a signal received from the opening operation unit 61, the closing operation unit 62, or the stop operation unit 63. Details of the processing executed by the control unit 93 will be described later.

(Configuration-Control Device-Memory Unit)
The memory unit 94 is a storage means for storing programs and various data necessary for the operation of the control device 90, and is configured using a rewritable recording medium, and can use a non-volatile recording medium such as a flash memory.

(Opening and closing process)
Next, a description will be given of the opening and closing process executed by the control device 90 of the control system 50. In the following description, steps will be abbreviated to "S" in the description of each process shown in FIG.

The opening/closing process is a process for controlling the opening/closing movement of the opening/closing body 30. The timing for executing this opening/closing process is arbitrary, but in the first embodiment, it is described as being started after the power supply of the opening/closing device 1 is turned on.

When the opening/closing process is started, as shown in FIG. 3, the opening/closing movement control unit 93a in SA1 determines whether an open signal, a close signal, or a stop signal has been received from the operating device 60. Here, in the first embodiment, as described above, the stop response time is shorter than the open response time and the close response time, so the stop signal can be received quickly, and processing based on the stop signal (stopping the opening/closing movement) can be performed quickly in SA2, which will be described later.

Then, the opening/closing movement control unit 93a transitions to SA2 if it determines that an opening signal or the like has been received (SA1, Yes), and transitions to SA3 if it determines that an opening signal or the like has not been received (SA1, No).

In SA2, the opening/closing movement control unit 93a opens/closes the opening/closing body 30 or stops the opening/closing movement of the opening/closing body 30 based on the opening signal received in SA1, etc.

Specifically, when an open signal or a close signal is received at SA1, a control signal corresponding to the open signal or the close signal (hereinafter referred to as an "open control signal" or "close control signal") is sent to the opening/closing device 40 to electrically release the brake of the opening/closing device 40 and drive the drive unit of the opening/closing device 40 to electrically close or open the opening/closing body 30. Here, in the first embodiment, even if the reception of an open signal or the like is stopped, the above control signal is continued to be sent to drive the drive unit of the opening/closing device 40, so that the closing or opening movement of the opening/closing body 30 continues. That is, the opening/closing movement of the opening/closing body 30 corresponding to the so-called "self-holding operation" is controlled (note that the same applies to the case where a stop signal is received). However, this is not limited to this, and for example, when the reception of a close signal or the like is stopped, the closing or opening movement of the opening/closing body 30 may also be stopped. That is, the opening/closing movement of the opening/closing body 30 corresponding to the so-called "push-through operation" may be controlled.

In addition, if a stop signal is received while the opening/closing body 30 is moving in a closed or open direction, a control signal corresponding to the stop signal (hereinafter referred to as a "stop control signal") is sent to the opening/closing machine 40 to stop the driving of the driving unit of the opening/closing machine 40, and the brake unit of the opening/closing machine 40 is actuated to stop the electrically driven closing or opening movement of the opening/closing body 30 (note that the same applies to the processing of SB5 described below).

At SA3, the opening/closing movement control unit 93a determines whether or not an obstacle is present at the opening 2.

While the method for determining whether or not an obstacle exists is arbitrary, in the first embodiment, the determination is made based on whether or not an obstacle detection signal is received from the seat switch 81 during processing of SA3. If an obstacle detection signal is received, it is determined that an obstacle exists, and if an obstacle detection signal is not received, it is determined that an obstacle does not exist.

Then, the opening/closing movement control unit 93a proceeds to SA4 if it determines that an obstacle is present (SA3, Yes), and proceeds to SA5 if it determines that an obstacle is not present (SA3, No).

In SA4, if the opening/closing movement of the opening/closing body 30 is continuing immediately before the processing of SA4, the opening/closing movement control unit 93a stops the opening/closing movement. Then, the process proceeds to SA1.

Here, the method of stopping the opening/closing movement of the opening/closing body 30 is arbitrary, but in the first embodiment, the opening/closing movement of the opening/closing body 30 is temporarily stopped (however, this stopping operation is limited to when the opening/closing body 30 is being opened/closed), and then the opening/closing body 30 is moved to an opening position higher than the current position, and then this opening movement is stopped (a so-called "touch-up operation" is performed). However, this is not limited to this, and for example, the opening/closing movement of the opening/closing body 30 may simply be stopped (a so-called "touch-stop operation" is performed).

In SA5, the opening/closing movement control unit 93a determines whether the opening/closing state of the opening/closing body 30 is fully closed or fully open.

While the method for determining whether the state is fully closed or fully open is arbitrary, in the first embodiment, the determination is made based on whether an upper limit detection signal or a lower limit detection signal is received from the upper limit detection unit 71 or the lower limit detection unit 72 during processing of SA5. If an upper limit detection signal or a lower limit detection signal is received, it is determined that the state is fully closed or fully open, and if an upper limit detection signal or a lower limit detection signal is not received, it is determined that the state is not fully closed or fully open.

Then, if it is determined that the opening/closing body 30 is in the fully closed or fully open state (SA5, Yes), the opening/closing movement control unit 93a proceeds to SA4 and stops the opening/closing movement of the opening/closing body 30. On the other hand, if it is determined that the opening/closing body 30 is not in the fully closed or fully open state (SA5, No), the opening/closing movement control unit 93a proceeds to SA1 and thereafter similarly repeats the processes from SA1 to SA5.

By performing the above-described opening and closing process, the opening and closing body 30 can be opened and closed, and the opening and closing state of the opening and closing body 30 can be changed depending on the situation.

(Effects of the First Embodiment)
Thus, according to embodiment 1, the stop response time is made shorter than the opening response time and shorter than the closing response time, so that the opening or closing movement of the opening/closing body 30 can be stopped quickly while suppressing malfunction of the opening or closing movement of the opening/closing body 30 compared to when the opening response time, closing response time, and stop response time are the same, thereby improving safety when using the opening/closing device 1.

In addition, the opening operation unit 61 is configured with a non-contact sensor that transmits an opening signal in an identifiable manner, the closing operation unit 62 is configured with a non-contact sensor that is separate from the opening operation unit 61 and transmits a closing signal in an identifiable manner, and the stop operation unit 63 is configured with a non-contact sensor (or push button) that is separate from the opening operation unit 61 and the closing operation unit 62 and transmits a stop signal in an identifiable manner, so that the opening operation , the closing operation , and the stop operation can be input individually using separate non-contact sensors (or push buttons), thereby improving the usability of the opening operation unit 61, the closing operation unit 62, and the stop operation unit 63.

[Embodiment 2]
Next, a control system according to a second embodiment will be described. In this second embodiment, the opening operation unit, the closing operation unit, and the stopping operation unit are integrally configured. However, the configuration of this second embodiment is substantially the same as that of the first embodiment, except where otherwise specified, and the configuration substantially the same as that of the first embodiment will be given the same reference numerals and/or names as those used in the first embodiment as necessary, and the description thereof will be omitted.

(composition)
First, the configuration of the opening and closing device according to the second embodiment will be described.

As shown in FIG. 4, the opening and closing device 101 according to the second embodiment is configured in a manner similar to that of the opening and closing device 1 according to the first embodiment. However, the details of the configuration of the operating device 60 and the control device 90 are modified as described below.

(Configuration - Operation Device Configuration Details)
Next, the configuration of the operation device 60 will be described in detail.

In the second embodiment, as shown in FIG. 4, the operating device 60 includes an opening operation unit 61, a closing operation unit 62, a stop operation unit 63, and an operating side receiving unit (not shown). Of these, the operating side receiving unit is an operating side communication means for communicating between the operating device 60 and the control device 90.

(Configuration - Details of the configuration of the operation device - Open operation unit, close operation unit, stop operation unit)
In addition, the specific configurations of the opening operation unit 61, the closing operation unit 62, and the stopping operation unit 63 are arbitrary, but in embodiment 2, the opening operation unit 61, the closing operation unit 62, and the stopping operation unit 63 are integrally configured by a single non-contact sensor.

Specifically, it is composed of one non-contact sensor that transmits the open signal, close signal, and stop signal as an indistinguishable signal. For example, it may be composed of an infrared contact sensor, a microwave contact sensor, or a transmission type photoelectric sensor, etc.

Here, an "indistinguishable signal" refers to a signal for transmitting an open signal, a close signal, or a stop signal in an indistinguishable manner (but which is identifiable enough to be received by the control device 90). An indistinguishable signal is, for example, a signal that does not include a specific identification code indicating that it is an open signal, a close signal, or a stop signal, and corresponds to a specific type of signal, etc.

This configuration reduces the number of parts and the manufacturing effort required for the opening operation unit 61, the closing operation unit 62, and the stopping operation unit 63, thereby improving the manufacturability of the opening operation unit 61, the closing operation unit 62, and the stopping operation unit 63.

The method for setting up the transmission of various signals from the single non-contact sensor is arbitrary, but in the second embodiment, it is set up as follows.

That is, when a signal indicating that the opening/closing body 30 is being moved to open or close (hereinafter referred to as an "opening/closing movement signal") is received from the control device 90 (specifically, the opening/closing movement control unit 93a), the response time from when an operation is performed on one of the non-contact sensors to when an indistinguishable signal is transmitted after the input of the operation is accepted (hereinafter referred to as an "indistinguishable response time") is set to be the same as the stop response time. Also, when an opening/closing movement signal is not received, the indistinguishable response time is set to be the same as the opening response time (or the closing response time).

By setting it in this way, when the opening/closing body 30 is moving to open or close, an unidentifiable signal can be sent quickly, and processing based on the unidentifiable signal (stopping the opening/closing movement) can be performed quickly. In addition, when the opening/closing movement of the opening/closing body 30 is stopped, erroneous sending of an unidentifiable signal can be suppressed, and processing based on the unidentifiable signal can be performed accurately.

(Configuration - Control Unit Configuration Details)
Next, the configuration of the control device 90 will be described in detail.

The control device 90 according to the second embodiment is configured in a manner similar to that of the control device 90 according to the first embodiment, as shown in FIG. 5. However, the configuration of the memory unit 94 is modified as described below.

(Configuration - Configuration details of control device - Storage unit)
As shown in FIG. 5, the storage unit 94 includes a first identification table 94a.

The first identification table 94a is a first identification storage means that stores information (hereinafter referred to as "identification information") for identifying whether an unidentifiable signal received from the operating device 60 is an open signal, a close signal, or a stop signal. As shown in FIG. 6, this first identification table 94a stores the items "movement state information", "open/close state information", and "identification information" and information corresponding to each item in a mutually associated manner.

Of these, the information corresponding to the item "moving state information" is moving state information indicating the moving state of the opening/closing body 30, such as the "open moving state" shown in FIG. 6. Also, the information corresponding to the item "opening/closing state information" is opening/closing state information indicating the opening/closing state of the opening/closing body 30, such as the "fully open state" shown in FIG. 6. Also, the information corresponding to the item "specific information" is specific information, such as the "stop signal" which is a signal to be specified, such as shown in FIG. 6. Note that "-" in FIG. 6 indicates that no information is stored.

(Opening and closing process)
Next, the opening and closing process executed by the control device 90 of the control system 50 will be described.

When the opening/closing process is started, as shown in FIG. 7, in SB1, the opening/closing movement control unit 93a determines whether or not an indistinguishable signal has been received from the operating device 60. Here, in the second embodiment, as described above, when the operating device 60 receives an opening/closing movement signal, the indistinguishable response time is set to the same as the stop response time, so that the indistinguishable signal can be received quickly. Therefore, in SB4 and SB5 described later, processing based on the indistinguishable signal (stopping the opening/closing movement) can be performed quickly, making it easier to ensure safety when using the opening/closing device 101.

Then, if it is determined that an unidentifiable signal has been received (SB1, Yes), the opening/closing movement control unit 93a proceeds to SB2, and if it is determined that an unidentifiable signal has not been received (SB1, No), it proceeds to SB6.

At SB2, the opening/closing movement control unit 93a determines the movement state of the opening/closing body 30.

The method of identifying the movement state of the opening/closing body 30 is arbitrary, but in the second embodiment, it is identified based on the type of control signal transmitted to the opening/closing device 40 during processing of SB1. Specifically, if an open control signal is transmitted, it is identified as being in an open movement state; if a close control signal is transmitted, it is identified as being in an open movement state; and if a stop control signal is transmitted, or if none of the open control signal, close control signal, or stop control signal is transmitted, it is identified as being in a stopped state.

At SB3, the opening/closing movement control unit 93a determines the open/close state of the opening/closing body 30.

The method of identifying the open/close state of the opening/closing body 30 is arbitrary, but in the second embodiment, it is identified based on the reception state of the upper limit detection signal or the lower limit detection signal from the upper limit detection unit 71 or the lower limit detection unit 72 during the processing of SB1. Specifically, when an upper limit detection signal is received, it is identified as being in a fully open state, when a lower limit detection signal is received, it is identified as being in a fully closed state, and when neither an upper limit detection signal nor a lower limit detection signal is received, it is identified as being in a half-open state.

In SB4, the opening/closing movement control unit 93a identifies the indistinguishable signal received from the operating device 60 (specifically, the one non-contact sensor) as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body 30 identified in SB2 and/or the opening/closing state of the opening/closing body 30 identified in SB3.

Specifically, from the specific information stored in the first specific table 94a, specific information corresponding to the movement state of the opening/closing body 30 identified in SB2 and/or the open/closed state of the opening/closing body 30 identified in SB3 is extracted, and the signal indicated by the extracted specific information is identified as the signal to be identified.

For example, as shown in FIG. 6, if the movement state of the opening/closing body 30 identified in SB2 is the open movement state, and the opening/closing state of the opening/closing body 30 identified in SB3 is the half-open state, the specific information corresponding to the open movement state is identified as the signal to be identified, that is, the stop signal.

Returning to FIG. 7, in SB5, the opening/closing movement control unit 93a opens/closes the opening/closing body 30 or stops the opening/closing movement of the opening/closing body 30 based on the signal identified in SB4.

Specifically, when an open signal is identified in SB4, the opening/closing body 30 is moved to the open position. When a close signal is identified in SB4, the opening/closing body 30 is moved to the closed position. When a stop signal is identified in SB4, the opening/closing movement of the opening/closing body 30 is stopped.

By processing SB4 and SB5 in this manner, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as an indistinguishable signal, the indistinguishable signal can be identified as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body 30 and/or the open/closed state of the opening/closing body 30, making it possible to accurately control the opening and closing movement of the opening/closing body 30.

In SB6, the opening/closing movement control unit 93a determines whether an obstacle is present in the opening 2, in a manner similar to the processing in SA3.

Then, if it is determined that an obstacle is present (SB6, Yes), the opening/closing movement control unit 93a proceeds to SB7, and if it is determined that an obstacle is not present (SB6, No), the opening/closing movement control unit 93a proceeds to SB8.

In SB7, the opening/closing movement control unit 93a stops the opening/closing movement of the opening/closing body 30 if the opening/closing movement is continuing immediately before the processing of SB7, in substantially the same manner as the processing of SA4. Then, the process proceeds to SB1.

In SB8, the opening/closing movement control unit 93a determines whether the opening/closing state of the opening/closing body 30 is fully closed or fully open, in a manner similar to the processing in SA5.

Then, if it is determined that the opening/closing body 30 is in the fully closed or fully open state (SB8, Yes), the opening/closing movement control unit 93a proceeds to SB7 and stops the opening/closing movement of the opening/closing body 30. On the other hand, if it is determined that the opening/closing body 30 is not in the fully closed or fully open state (SB8, No), the opening/closing movement control unit 93a proceeds to SB1 and thereafter similarly repeats the processes from SB1 to SB8.

By performing the above-described opening and closing process, the opening and closing movement of the opening and closing body 30 can be performed in substantially the same manner as the opening and closing process according to embodiment 1, and the opening and closing state of the opening and closing body 30 can be changed according to the situation.

(Effects of the Second Embodiment)
Thus, according to embodiment 2, the opening operation unit 61, the closing operation unit 62, and the stop operation unit 63 are integrated into a single non-contact sensor, thereby reducing the number of parts and the manufacturing effort required for the opening operation unit 61, the closing operation unit 62, and the stop operation unit 63, and improving the manufacturability of the opening operation unit 61, the closing operation unit 62, and the stop operation unit 63.

In addition, the opening/closing movement control unit 93a identifies an indistinguishable signal received from one non-contact sensor as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body 30 and/or the open/closed state of the opening/closing body 30, and controls the opening/closing movement of the opening/closing body 30 based on the identified open signal, close signal, or stop signal. Therefore, when one non-contact sensor transmits an open signal, a close signal, or a stop signal as an indistinguishable signal, the indistinguishable signal can be identified as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body 30 and/or the open/closed state of the opening/closing body 30, making it possible to accurately control the opening/closing movement of the opening/closing body 30.

In addition, when an opening/closing movement in progress signal is received from the opening/closing movement control unit 93a, the response time from when an operation is performed at one non-contact sensor to when an indistinguishable signal is transmitted after the input of the operation is accepted is set to be the same as the stop response time, and when the opening/closing movement control unit 93a is moving the opening/closing body 30 to the open position or the close position, the indistinguishable signal received from one non-contact sensor is identified as a stop signal. Therefore, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as an indistinguishable signal, the opening or closing movement of the opening/closing body 30 can be quickly stopped, making it easier to ensure safety when using the opening/closing device 101.

Third Embodiment
Next, a control system according to a third embodiment will be described. In this third embodiment, one non-contact sensor transmits two indistinguishable signals. However, the configuration of this third embodiment is substantially the same as that of the second embodiment, unless otherwise specified, and the configuration substantially the same as that of the second embodiment will be given the same reference numerals and/or names as those used in the second embodiment as necessary, and the description thereof will be omitted.

(composition)
First, the configuration of the opening and closing device according to the third embodiment will be described.

The opening and closing device 201 according to the third embodiment is configured in a manner similar to the opening and closing device 101 according to the second embodiment. However, the details of the configuration of the operating device 60 and the control device 90 are modified as described below.

(Configuration - Operation Device Configuration Details)
Next, the configuration of the operation device 60 will be described in detail.

The operating device 60 according to the third embodiment includes an opening operation unit 61, a closing operation unit 62, and a stopping operation unit 63.

The specific configuration of the opening operation unit 61, the closing operation unit 62, and the stopping operation unit 63 can be arbitrary, but in the third embodiment, they are integrated into a single non-contact sensor.

Specifically, the open signal, close signal, and stop signal are configured with one non-contact sensor that transmits a first signal, which is an indistinguishable signal, and transmits a second signal, which is an indistinguishable signal, a predetermined time after the transmission of the first signal (e.g., 0.5 sec, etc.). For example, the sensor may be configured with an infrared contact sensor, a microwave contact sensor, or a transmission type photoelectric sensor, etc.

With this configuration, compared to the operating device 60 according to embodiment 2, it is not necessary to change the settings of the unidentifiable response time, making it possible to easily transmit an unidentifiable signal.

In addition, the setting method for transmitting the first signal in the one non-contact sensor is arbitrary, but in embodiment 3, the response time from when an operation is performed in the one non-contact sensor to when the first signal is transmitted after the operation input is accepted (hereinafter referred to as the "first response time") is set to be the same as the stop response time.

This setting allows the first signal to be sent quickly, and processing based on the first signal (stopping the opening/closing movement) can be performed quickly.

(Configuration - Control Unit Configuration Details)
Next, the configuration of the control device 90 will be described in detail.

As shown in FIG. 8, the control device 90 according to the third embodiment is configured in a manner similar to that of the control device 90 according to the second embodiment. However, the memory unit 94 is configured as described below.

(Configuration - Configuration details of control device - Storage unit)
As shown in FIG. 8, the storage unit 94 includes a second identification table 94b.

The second identification table 94b is a second identification storage means that stores information for identifying whether the first signal received from the operating device 60 is an open signal, a close signal, or a stop signal (hereinafter referred to as "first identification information"), and information for identifying whether the second signal received from the operating device 60 is an open signal, a close signal, or a stop signal (hereinafter referred to as "second identification information"). As shown in FIG. 9, this second identification table 94b stores the items "movement state information", "open/close state information", "first identification information", and "second identification information" and information corresponding to each item in a mutually associated manner.

Of these, the information corresponding to the item "moving state information" is moving state information. Moreover, the information corresponding to the item "opening/closing state information" is open/closed state information. Moreover, the information corresponding to the item "first specific information" is first specific information, such as the "stop signal" that is a signal to be specified as shown in FIG. 9. Moreover, the information corresponding to the item "second specific information" is second specific information, such as the "open signal" that is a signal to be specified as shown in FIG. 9 (note that "close signal" may be used instead of "open signal"). Note that "-" in FIG. 9 indicates that no information is stored.

(Opening and closing process)
Next, the opening and closing process executed by the control device 90 of the control system 50 will be described.

When the opening/closing process is started, as shown in FIG. 10, the opening/closing movement control unit 93a determines in SC1 whether or not a first signal has been received from the operating device 60. Then, if it is determined that the first signal has been received (SC1, Yes), the opening/closing movement control unit 93a proceeds to SC2, and if it is determined that the first signal has not been received (SC1, No), the opening/closing movement control unit 93a proceeds to SC6.

In SC2, the opening/closing movement control unit 93a determines the movement state of the opening/closing body 30 in a manner substantially similar to the processing in SB2.

In SC3, the opening/closing movement control unit 93a identifies the open/closed state of the opening/closing body 30 in substantially the same manner as in the process of SB3.

In SC4, the opening/closing movement control unit 93a determines whether the first signal received in SC1 can be identified as a stop signal based on the movement state of the opening/closing body 30 identified in SC2 and/or the opening/closing state of the opening/closing body 30 identified in SC3.

While there is any method for determining whether or not this first signal can be identified as a stop signal, in the third embodiment, the first identification information stored in the second identification table 94b is extracted that corresponds to the movement state of the opening/closing body 30 identified in SC2 and/or the open/closed state of the opening/closing body 30 identified in SC3, and a determination is made based on whether or not the signal indicated by the extracted first identification information is a stop signal. Here, if the signal indicated by the first identification information is a stop signal, it is determined that the signal can be identified as a stop signal, and if the signal indicated by the first identification information is not a stop signal, it is determined that the signal cannot be identified as a stop signal.

For example, as shown in FIG. 9, when the movement state of the opening/closing body 30 identified by SC2 is the open movement state, the first identification information corresponding to the open movement state is identified as a stop signal, and it is determined that the first signal can be identified as a stop signal.

Returning to FIG. 10, if the opening/closing movement control unit 93a determines that the first signal can be identified as a stop signal (SC4, Yes), it identifies the first signal as a stop signal (i.e., if the opening/closing body 30 is being moved to open or close, it identifies the first signal as a stop signal) and proceeds to SC5. On the other hand, if it determines that the first signal cannot be identified as a stop signal (SC4, No), it does not identify the first signal as a stop signal (i.e., if the opening/closing movement of the opening/closing body 30 is stopped, it ignores the first signal) and proceeds to SC6.

At SC5, the opening/closing movement control unit 93a stops the opening/closing movement of the opening/closing body 30.

By processing SC4 and SC5 in this manner, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as the first signal and the second signal, the opening or closing movement of the opening/closing body 30 can be stopped quickly, making it easier to ensure safety when using the opening/closing device 201.

In SC6, the opening/closing movement control unit 93a determines whether or not a second signal has been received from the operating device 60. If it is determined that the second signal has been received (SC6, Yes), the opening/closing movement control unit 93a proceeds to SC7, and if it is determined that the second signal has not been received (SC6, No), the opening/closing movement control unit 93a proceeds to SC9.

In SC7, the opening/closing movement control unit 93a determines whether the second signal received in SC6 can be identified as an open signal or a close signal based on the movement state of the opening/closing body 30 identified in SC2.

While there is any method for determining whether this second signal can be identified as an open signal or a close signal, in the third embodiment, from the second identification information stored in the second identification table 94b, second identification information corresponding to the movement state of the opening/closing body 30 identified in SC2 and/or the open/closed state of the opening/closing body 30 identified in SC3 is extracted, and a determination is made based on whether the signal indicated by the extracted second identification information is an open signal or a close signal. Here, if the signal indicated by the second identification information is an open signal or a close signal, it is determined that the signal can be identified as an open signal or a close signal, and if the signal indicated by the second identification information is not an open signal or a close signal, it is determined that the signal cannot be identified as an open signal or a close signal.

For example, as shown in FIG. 9, if the movement state of the opening/closing body 30 identified in SC2 is a stopped state and the opening/closing state of the opening/closing body 30 identified in SC3 is a fully open state, the second identification information corresponding to the closed movement state is identified as a closed signal, and it is determined that the second signal can be identified as an open signal or a closed signal.

Returning to FIG. 10, if the opening/closing movement control unit 93a determines that the second signal can be identified as an open signal or a close signal (SC7, Yes), it identifies the second signal as an open signal or a close signal (i.e., if the opening or closing movement of the opening/closing body 30 is stopped, it identifies the second signal as an open signal or a close signal) and proceeds to SC8. On the other hand, if it determines that the second signal cannot be identified as an open signal or a close signal (SC7, No), it does not identify the second signal as an open signal or a close signal (i.e., if the opening/closing body 30 is being opened or closed, it ignores the second signal) and proceeds to SC9.

In SC8, the opening/closing movement control unit 93a opens and closes the opening/closing body 30 based on the open signal or close signal identified in SC7.

Specifically, when an open signal is identified in SC7, the opening/closing body 30 is moved to the open position. Also, when a close signal is identified in SC7, the opening/closing body 30 is moved to the closed position.

In SC9, the opening/closing movement control unit 93a determines whether an obstacle is present in the opening 2, in a manner similar to the processing in SB6.

Then, if it is determined that an obstacle is present (SC9, Yes), the opening/closing movement control unit 93a proceeds to SC10, and if it is determined that an obstacle is not present (SC9, No), it proceeds to SC11.

In SC10, the opening/closing movement control unit 93a stops the opening/closing movement of the opening/closing body 30 if the opening/closing movement is continuing immediately before the processing of SC10, substantially similar to the processing of SB7. Then, the process proceeds to SC1.

In SC11, the opening/closing movement control unit 93a determines whether the opening/closing state of the opening/closing body 30 is fully closed or fully open, in a manner similar to the processing in SB8.

Then, if the opening/closing movement control unit 93a determines that the opening/closing body 30 is in the fully closed or fully open state (SC11, Yes), it transitions to SC10 and stops the opening/closing movement of the opening/closing body 30. On the other hand, if the opening/closing body 30 is not in the fully closed or fully open state (SC11, No), it transitions to SC1 and thereafter similarly repeats the processes from SC1 to SC11.

By performing the above-described opening and closing process, the opening and closing body 30 can be opened and closed in a manner similar to that of the opening and closing process according to embodiment 2, and the opening and closing state of the opening and closing body 30 can be changed according to the situation.

(Effects of the Third Embodiment)
Thus, according to embodiment 3, the response time from when an operation is performed at one non-contact sensor to when the first signal is transmitted after the input of the operation is accepted is set to be the same as the stop response time, and when the opening/closing movement control unit 93a is moving the opening/closing body 30 to open or close, it identifies the first signal received from the one non-contact sensor as a stop signal and ignores the second signal received from the one non-contact sensor, and when it is stopping the opening or closing movement of the opening/closing body 30, it ignores the first signal received from the one non-contact sensor and identifies the second signal received from the one non-contact sensor as an open or close signal. Therefore, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as the first signal and the second signal, the opening or closing movement of the opening/closing body 30 can be quickly stopped, making it easier to ensure safety when using the opening/closing device 201.

[III] Modifications to the embodiment The embodiment of the present invention has been described above, but the specific configuration 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 functionally conceptual, 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. In addition, the "device" in this application is not limited to one configured by a single device, but includes one configured by multiple devices. For example, the control device 90 may be distributed and configured into multiple devices configured to be able to communicate with each other, and a control unit 93 may be provided in some of these multiple devices, and a memory unit 94 may be provided in another part of these 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.

(Regarding the control system)
In the above-mentioned first to third embodiments, the control system 50 is described as including the upper limit detection unit 71, the lower limit detection unit 72, the seat board switch 81, and the cord reel 82, but is not limited to this. For example, instead of the upper limit detection unit 71, the lower limit detection unit 72, the seat board switch 81, and the cord reel 82, a position detection unit and a rotation speed detection unit may be provided.

Here, the position detection unit is a position detection means for detecting the position of the opening/closing body 30 (specifically, the position of the closing side end described below) and outputting a signal indicating the detected position (hereinafter referred to as the "position signal") at a predetermined cycle. The rotation speed detection unit is a rotation speed detection means for detecting the rotation speed of the drive unit of the opening/closing device 40 (hereinafter referred to as the "drive unit rotation speed") and outputting a signal indicating the detected rotation speed (hereinafter referred to as the "rotation speed signal") at a predetermined cycle. The specific configurations of the position detection unit and the rotation speed detection unit are arbitrary, but may be configured, for example, using a Hall IC or the like that has the functions of both the position detection unit and the rotation speed detection unit.

Such a position detection unit and rotation speed detection unit can determine the open/closed state of the opening/closing body 30 based on the position signal, and can determine whether an obstacle is present based on the rotation speed signal.

In addition, in the above embodiments 1 to 3, it has been described that the obstacle detection signal from the seat switch 81 is transmitted to the control device 90 using the cord reel 82, but this is not limited to the above. For example, the cord reel 82 may be omitted. The obstacle detection signal from the seat switch 81 may be wirelessly transmitted by a wireless transmitting unit, and the transmitted obstacle detection signal may be received by a wireless receiving unit and then transmitted to the control device 90.

(Regarding the operating device)
In the above embodiment 2, it was described that the operating device 60 (specifically, one non-contact sensor) transmits the open signal, close signal, and stop signal as indistinguishable signals, but this is not limited thereto, and the open signal, close signal, and stop signal may be transmitted in an identifiable manner.

As an example, the operation device 60 may distinguishably accept inputs of an opening operation, a closing operation, and a stopping operation, which are different from each other, and distinguishably transmit a signal (an opening signal, a closing signal, or a stopping signal) corresponding to the accepted operation input . Alternatively, the operation device 60 may receive signals indicating the movement state information and the opening/closing state information from the control device 90, and when an operation input is accepted, may distinguishably transmit an opening signal, a closing signal, or a stopping signal based on the received movement state information and the opening/closing state information while referring to the first identification table 94a.

In addition, in the above embodiment 2, it has been described that the stop operation unit 63 is configured with an infrared non-contact sensor, but this is not limited to this. For example, it may be configured with a non-contact sensor or push button of a different type from the opening operation unit 61 and the closing operation unit 62, and with a stop response time that is shorter than the opening response time of the opening operation unit 61 and the closing response time of the closing operation unit 62 (such as a transmissive photoelectric sensor, for example) or push button.

(About opening and closing process)
In the first embodiment, the opening and closing device 1 executes the opening and closing process according to the first embodiment, but this is not limited thereto. For example, in addition to the opening and closing process according to the first embodiment, the opening and closing process according to the second embodiment or/the opening and closing process according to the third embodiment may be executed.

As an example, in order to be able to execute the opening and closing process according to embodiment 2, the control unit 93 may include a switching means for switching between a first control mode for executing the opening and closing process according to embodiment 1 and a second control mode for executing the opening and closing process according to embodiment 2, and the storage unit 94 may include a first identification table 94a. Then, when the control mode is switched to the first control mode by the switching means, the opening and closing process according to embodiment 1 may be executed, and when the control mode is switched to the second control mode by the switching means, the opening and closing process according to embodiment 2 may be executed (note that the same applies to the case where the opening and closing process according to embodiment 3 can be executed).

(Additional Note)
The control system of Appendix 1 is a control system for controlling an opening/closing device having an opening/closing body for opening and closing an opening of a building, and is equipped with an opening operation means which, when receiving an opening operation input in a non-contact manner, transmits an opening signal corresponding to the opening operation input for moving the opening/closing body in an open position, a closing operation means which, when receiving a closing operation input in a non-contact manner, transmits a closing signal corresponding to the closing operation input for moving the opening/closing body in a closed position, a stop operation means which, when receiving a stop operation input in a contact or non-contact manner, for stopping the opening or closing movement of the opening/closing body, transmits a stop signal corresponding to the stop operation input, and an opening/closing movement control means which controls the opening/closing movement of the opening/closing body based on a signal received from the opening operation means, the closing operation means, or the stop operation means, and a stop response time which is the response time from receiving the stop operation input in the stop operation means to transmitting the stop signal is shorter than an opening response time which is the response time from receiving the opening operation input in the closing operation means to transmitting the opening signal, and is shorter than a closing response time which is the response time from receiving the closing operation input in the closing operation means to transmitting the close signal.

The control system of Appendix 2 is the control system described in Appendix 1, in which the opening operation means is configured with a non-contact sensor that identifiably transmits the opening signal, the closing operation means is configured with a non-contact sensor that is separate from the opening operation means and that identifiably transmits the closing signal, the stop operation means is configured with a non-contact sensor or a push button that is separate from the opening operation means and the closing operation means and that identifiably transmits the stop signal, and the opening/closing movement control means controls the opening/closing movement of the opening/closing body based on the opening signal, the closing signal, or the stop signal received from the opening operation means, the closing operation means, or the stop operation means.

The control system of Appendix 3 is the control system described in Appendix 1, in which the opening operation means, the closing operation means, and the stopping operation means are integrated into a single non-contact sensor.

The control system of Appendix 4 is the control system described in Appendix 3, in which the one non-contact sensor transmits the open signal, the close signal, and the stop signal as an indistinguishable signal that transmits the open signal, the close signal, and the stop signal in an indistinguishable manner, and the opening/closing movement control means identifies the indistinguishable signal received from the one non-contact sensor as the open signal, the close signal, or the stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, and controls the opening/closing movement of the opening/closing body based on the identified open signal, close signal, or stop signal.

The control system of Appendix 5 is the control system described in Appendix 4, in which, when the one non-contact sensor receives an opening/closing movement in progress signal from the opening/closing movement control means indicating that the opening/closing body is being opened or closed, the response time from receipt of an operation input in the one non-contact sensor to transmission of the indistinguishable signal is set to be the same as the stop response time, and the opening/closing movement control means identifies the indistinguishable signal received from the one non-contact sensor as the stop signal when the opening/closing body is being opened or closed.

The control system of Appendix 6 is the control system described in Appendix 4, in which the one non-contact sensor transmits a first signal that is the indistinguishable signal and transmits a second signal that is the indistinguishable signal a predetermined time after transmitting the first signal, the response time from receiving an operation input in the one non-contact sensor to transmitting the first signal is set to be the same as the stop response time, and the opening/closing movement control means, when the opening/closing body is being moved to open or close, identifies the first signal received from the one non-contact sensor as the stop signal and ignores the second signal received from the one non-contact sensor, and, when the opening/closing movement of the opening/closing body is stopped, ignores the first signal received from the one non-contact sensor and identifies the second signal received from the one non-contact sensor as the open signal or the close signal.

(Effect of supplementary notes)
According to the control system described in Appendix 1, the stop response time is made shorter than the open response time and shorter than the close response time, so that the opening or closing movement of the opening/closing body can be stopped quickly while suppressing malfunction of the opening or closing movement of the opening/closing body, compared to when the opening response time, closing response time, and stop response time are the same, thereby improving safety when using the opening/closing device.

According to the control system described in Appendix 2, the opening operation means is configured with a non-contact sensor that transmits an identifiable opening signal, the closing operation means is configured with a non-contact sensor that is separate from the opening operation means and transmits an identifiable closing signal, and the stopping operation means is configured with a non-contact sensor or push button that is separate from the opening operation means and the closing operation means and transmits an identifiable stopping signal. Therefore, the opening operation input, closing operation input, and stopping operation input can be individually performed with separate non-contact sensors (or push buttons), and the usability of the opening operation means, closing operation means, and stopping operation means can be improved.

According to the control system described in Appendix 3, the opening operation means, closing operation means, and stopping operation means are integrated into a single non-contact sensor, which reduces the number of parts and the manufacturing effort required for the opening operation means, closing operation means, and stopping operation means, thereby improving the manufacturability of the opening operation means, closing operation means, and stopping operation means.

According to the control system described in Appendix 4, the opening/closing movement control means identifies an indistinguishable signal received from one non-contact sensor as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, and controls the opening/closing movement of the opening/closing body based on the identified open signal, close signal, or stop signal. Therefore, when one non-contact sensor transmits an open signal, a close signal, or a stop signal as an indistinguishable signal, the indistinguishable signal can be identified as an open signal, a close signal, or a stop signal based on the movement state of the opening/closing body and/or the open/closed state of the opening/closing body, making it possible to accurately control the opening/closing movement of the opening/closing body.

According to the control system described in Appendix 5, when an opening/closing movement signal is received from the opening/closing movement control means, the response time from receipt of an operational input in one non-contact sensor to transmission of an indistinguishable signal is set to be the same as the stop response time, and when the opening/closing movement control means is moving the opening/closing body to open or close, the indistinguishable signal received from one non-contact sensor is identified as a stop signal. Therefore, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as an indistinguishable signal, the opening or closing movement of the opening/closing body can be stopped quickly, making it easier to ensure safety when using the opening/closing device.

According to the control system described in Appendix 6, the response time from receipt of an operation input in one non-contact sensor to transmission of a first signal is set to be the same as the stop response time, and when the opening/closing movement control means is moving the opening/closing body to open or close, it identifies the first signal received from one non-contact sensor as a stop signal and ignores the second signal received from one non-contact sensor, and when it is stopping the opening or closing movement of the opening/closing body, it ignores the first signal received from one non-contact sensor and identifies the second signal received from one non-contact sensor as an open or close signal. Therefore, when one non-contact sensor transmits an open signal, a close signal, and a stop signal as the first signal and the second signal, it is possible to quickly stop the opening or closing movement of the opening/closing body, making it easier to ensure safety when using the opening/closing device.
