Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for automatic doors installed in structures such as buildings.

When opening and closing an automatic door, in order to reduce the effectiveness of indoor air conditioning in summer and winter, and to prevent bad outdoor environments such as noise and strong winds from entering the room, it is necessary to open the door for a shorter time than usual or close the door. It is only necessary to make the open area smaller than usual. One way to make the door open time shorter than usual is to increase the door opening/closing speed, and one way to reduce the opening area of the door is to shorten the door opening/closing stroke. Conventionally, in this type of automatic door control device, the adjustment of the door opening/closing speed and the door opening/closing stroke were manually performed by digital adjustment using a selection switch or the like, or analog adjustment using a volume control or the like. For example, if the user determines that the temperature difference between outdoors and indoors has become large during indoor air conditioning in summer or winter, the user may increase the door opening/closing speed by adjusting the selection switch or volume, or the door opening/closing stroke. By making it smaller, the reduction in indoor air conditioning effectiveness was suppressed. however,
When the door opening/closing speed and door opening/closing stroke are artificially set using the selection switch, volume, etc. as described above, the setting takes time and effort for the user, and the standards for the door opening/closing speed and door opening/closing stroke are set. The settings depend on the sense of the user who makes the adjustment, and the settings are not necessarily optimal, and also change from hour to hour, such as the temperature change from morning to noon to evening. It was virtually impossible to adjust the settings to suit the environment.

This invention was made in view of the above circumstances, and automatically optimizes the two setting elements of the door opening/closing speed and the door opening/closing stroke, either alone or together, according to the internal and external environments of the automatic door. The present invention provides an automatic door control device that has a function that allows adjustment to a set value. These automatic door control devices are characterized by an environmental detector installed inside or outside the automatic door, or both, and an environmental judgment unit that determines the environment based on the data detected by the environmental detector. a command section that commands a door opening/closing speed or a door opening/closing speed and a door opening/closing stroke according to the environment determined by the environment determining section; a storage section that provides setting data to the environment determining section and the command section; and the command section. The door opening/closing control section has a function of adjusting the door opening/closing speed, or the door opening/closing speed and the door opening/closing stroke according to the command.

First, an embodiment in which only the door opening/closing speed is adjusted will be described based on FIG. 1.

In this embodiment, first, the environmental detectors 1 are, for example, an outdoor temperature sensor 1a, an outdoor humidity sensor 1b, an outdoor wind speed sensor 1c, an outdoor noise detector 1d, an indoor temperature sensor 1e, and an indoor humidity detector. 1f
are installed individually or in combination inside and outside the automatic door,
The environment detectors 1, for example, the above-mentioned 1a to 1f are connected to an environment determining section 2. The environment judgment section 2 is connected to a command section 3, and a storage section 4 is connected to both the environment judgment section 2 and the command section 3. The command unit 3 is further connected to a door opening/closing control unit 5 , and an open timer circuit 6 , a door position detection unit 7 , a speed detection unit 8 , etc. are connected to the door opening/closing control unit 5 . is connected to the drive circuit 9. or,
The open timer circuit 6 is connected to a passing body detection section 10 that detects passing bodies attempting to enter or exit.

Next, the operation of the block circuit diagram of FIG. 1 constructed as described above will be explained.

The environment detector 1 outputs each measured data to the environment judgment section 2, and the environment judgment section 2 receives each of the data input from the environment sensor 1 and a reference value as setting data provided from the storage section 4. By comparing the two, environmental judgments such as energy saving mode, normal mode, open mode, etc. are made, and the judgment is given to the command unit 3 as information. Further, the environment judgment section 2 displays each data from the environment detector 1 on the display section 2a.
It can also be output to and displayed on a monitor.

The command unit 3 receives the setting data from the storage unit 4,
The command data for each mode is input, and among these command data, a door opening/closing speed command, which is command data that matches the information given from the environment judgment section 2, is sent to the door opening/closing control section 5. .

The door opening/closing control unit 5 responds to the door opening/closing speed command issued from the command unit 3 when the judgment of the environment judgment unit 2 is the normal mode by setting the door opening/closing speed to an arbitrarily set normal speed (for example, 0.3 m). /sec) to open and close the door, and in response to the door opening/closing speed command from the command unit 3 issued when the environment judgment unit 2 determines that the energy saving mode is selected, the door opening/closing time is In order to shorten the time, the drive circuit 9 is controlled to open and close the door at a speed faster than the normal speed (for example, 0.6 m/sec), and when the judgment of the environment judgment section 2 is in the open mode, In response to the command from the command unit 3, the drive circuit 9 is controlled to keep the door open under normal conditions. That is, when the environment judgment unit 2 determines the normal mode or the energy saving mode, the door opening/closing control unit 5 receives an open or close signal from the open timer circuit 6 output based on a detection signal from the pedestrian detection unit 10. The stop/operation command unit 5 in the door opening/closing control unit 5 operates in accordance with the door opening/closing speed command sent from the command unit 3.
a outputs an operation command of a predetermined speed corresponding to each command speed in the normal mode and the energy saving mode to the calculation unit 5b in the door opening/closing control unit 5. This calculation section 5b compares the predetermined speed commanded from the stop/operation command section 5a with the momentary door speed data from the speed detection section 8, and issues an operation command so that the deviation value of the speed becomes 0. is sent to the forward/reverse rotation output section 5c in the door opening/closing control section 5, and the stop/operation command section 5
a sends a forward or reverse rotation command to the forward/reverse rotation output section 5c based on the open or close signal from the open timer circuit 6, and this forward/reverse rotation output section 5c sends an operation command and an operation command based on the speed deviation value. An open or close control signal is sent to the drive circuit 9 based on a command for forward or reverse rotation. Then, the stop/operation command section 5a
receives a signal from the door position detection unit 7 when the door reaches the cushion position and sends a cushion command to the forward/reverse rotation output unit 5c, and receives a signal when the door reaches the fully open or fully closed position to perform forward/reverse rotation. A command to stop the operation is sent to the output section 5c. However, the method of controlling the drive circuit 9 by the door opening/closing control section 5 shown here is an example, and the contents of the door opening/closing control section 5 are not limited to the above description and what is shown in FIG. , command section 3
Any device may be used as long as it can adjust the door opening/closing speed in response to commands for each mode sent to the door opening/closing unit 5 from the door opening/closing unit 5.

Next, an embodiment in which the door opening/closing speed and door opening/closing stroke are adjusted will be described based on FIG. 2.

The environment detectors 1 include an outdoor temperature sensor 1a, an outdoor humidity sensor 1b, an outdoor wind speed sensor 1c, an outdoor noise detector 1b, and an indoor temperature sensor, as in the above embodiment in which only the door opening/closing speed is adjusted. Vessel 1
e. Indoor humidity detectors 1f are installed either singly or in combination inside and outside the automatic door, and these environmental detectors 1, for example 1a to 1f, are connected to an environment determining section 2. A storage section 4 is connected to both the environment judgment section 2 and the command section 3'. The command unit 3' further includes:
Two types of connection wires, one for door opening/closing speed and one for door opening/closing stroke, are connected to the door opening/closing control section 5', and the door opening/closing control section 5' has an open timer circuit 6, a door position detection section 7, and a speed detection section. section 8 is connected. The door opening/closing control section 5' is further connected to a drive circuit 9. Also, connected to the open timer circuit 6 is a passing body detection section 10 that detects passing bodies attempting to enter or exit.

Next, the operation of the block circuit diagram shown in FIG. 2 will be explained.

The environment detector 1 outputs each measured data to the environment judgment section 2, and the environment judgment section 2 outputs each of the data inputted from the environment sensor 1 and a reference value as setting data provided from the storage section 4. By comparing the values, environmental judgments such as energy saving mode, normal mode, open mode, etc. are made, and the judgment is given to the command section 3' as information. Also, environmental judgment department 2
It is also possible to output each data from the environment detector 1 to the display section 2a and display it on a monitor.

The command unit 3' receives the setting data from the storage unit 4,
The command data for each mode is inputted, and among the command data, commands for the door opening/closing speed and door opening/closing stroke, which are finger data that match the information given from the environment judgment section 2, are sent to the door opening/closing control section 5'. is being sent to.

The door opening/closing control unit 5' is arbitrarily set in response to the door opening/closing speed and door opening/closing stroke commands issued from the command unit 3' when the judgment of the environment judgment unit 2 is the normal mode. When the drive circuit 9 is controlled to open and close the door at a normal speed (for example, 0.3 m/sec) and a normal opening/closing stroke (for example, an opening/closing stroke to the fully open position), and the environment judgment unit 2 determines that it is the energy saving mode. In response to the door opening/closing speed and door opening/closing stroke commands issued from the command unit 3', in order to shorten the door opening/closing time,
A speed faster than the normal speed (e.g. 0.6m/
sec) and in order to reduce the open area of the door, the drive circuit 9 is controlled to open and close the door at the normal opening/closing stroke (for example, the opening/closing stroke to the half-open position). That is, when the environment judgment section 2 determines that it is the normal mode or the energy saving mode, the door opening/closing control section 5' opens the door from the open timer circuit 6 outputted based on the detection signal from the pedestrian object detection section 10, or Operates upon receiving a close signal,
In this door opening/closing control section 5', a first arithmetic circuit 5
d' compares and calculates the door opening/closing stroke commanded from the above-mentioned command section 3' and the momentary door position data sent from the door position detection section 7, and uses this calculated value as the stop/operation command section. Sending to 5a'. The stop/operation command section 5a' sends a door operation command to the forward/reverse rotation output section 5c' in response to each command opening/closing stroke in the normal mode and energy saving mode based on the calculated value sent from the first calculation circuit 5d'. The forward/reverse rotation output section 5c' sends an operating signal to the drive circuit 9 in response to this command. Also, at the same time, the stop/operation command section 5
a' is determined by the door opening/closing speed command from the command unit 3'.
An operation command for a predetermined speed corresponding to each command speed in the normal mode and the energy saving mode is sent to the second arithmetic circuit 5b'. The stop/operation command section 5
The second arithmetic circuit 5b' receives data on the predetermined speed specified from a' and the door speed from the speed detection section 8, and sends an operation command to the forward/reverse rotation output section 5c' so that the deviation value becomes 0. , and the stop/operation command section 5
a' sends a forward or reverse rotation command to the forward/reverse rotation output section 5c' based on the open or close signal from the open timer circuit 6; An open or close control signal is sent to the drive circuit 9 based on an operation command based on the speed deviation value sent and a forward rotation or reverse rotation command sent from the stop/operation command section 5a'. When the door reaches the cushion position, a cushion position command is sent to the stop/operation command section 5a' via the first arithmetic circuit 5d', and this stop/operation command section 5a' is in turn sent to the forward/reverse rotation output section 5c'. A command for actuating the cushion is sent to the stop/operation command section 5a' when the door reaches the open position or fully open position corresponding to the opening/closing stroke position commanded from the command section 3'. When the calculated value from the 1 calculation circuit 5d' becomes 0, it is determined that the door position has reached the commanded opening/closing stroke, and an operation stop command is sent to the forward/reverse rotation output section 5c'.
Note that, when a command for the open mode is sent from the command section 3', the door opening/closing control section 5' controls the drive circuit 9 to keep the door open at all times. However, the door opening/closing control section 5' shown in FIG. Any device may be used as long as it can adjust the door opening/closing speed and the door opening/closing stroke in response to received commands for each mode, and is not limited to the one in the embodiment.

In the above two embodiments, the environment judgment unit 2
Let me give an example and explain how to judge. For example, if there is a temperature difference between the inside and outside of the automatic door due to air conditioning using an air conditioner in the summer or winter, the storage unit 4
The reference value of the difference between the outdoor temperature and indoor temperature given to the environment judgment unit 2 is set to 5°C, and the data actually sent from the outdoor temperature sensor 1a and the indoor temperature sensor 1e are
When the temperature difference between the inside and outside of the automatic door, obtained as the difference between the data sent from In order to suppress the decline in air conditioning effectiveness by reducing the
The temperature difference between the inside and outside of the automatic door obtained as the difference between the data sent from the indoor temperature sensor 1e and the standard value of 5°C
If it is less than 1, the environment judgment unit 2 sends the environment judgment of the normal mode to the command unit 3. Hereinafter, as an example of the case where the environment judgment unit 2 makes an environment judgment of the energy saving mode for the environment detector 1 shown in the embodiment,
Data from outdoor temperature sensor 1a is 5℃ in winter etc.
or when the humidity difference between the inside and outside of the automatic door, obtained as the difference between the data of the outdoor humidity detector 1b and the indoor humidity detector 1f, becomes 10% or more due to air conditioning during the rainy season, etc. , when the data from the outdoor wind speed detector 1c exceeds 10 m/sec during a typhoon, etc., or when the data from the outdoor noise detector 1d exceeds 50 dB due to construction work or an increase in car traffic, etc. can be mentioned. Also, environmental judgment department 2
An example of a case where the system makes an environmental judgment for open mode is when it is necessary to open the door to secure an evacuation route in the event of a fire. For example, if the data from the indoor temperature sensor 1e exceeds 50℃ This may be the case. Environmental judgment unit 2 other than when making environmental judgments for energy saving mode or open mode
The environment judgment will be in normal mode. However, the judgment criteria for each mode of the environment judgment unit 2 shown here, that is, the reference values given from the storage unit 4, are just examples and can be changed as necessary. The types of judgments such as differences are not limited to the above. Furthermore, the type of environmental detector 1 is not limited to the above embodiments, and may be smaller in number than in each embodiment. For example, it may be an air pollution level detector that detects the outdoor air pollution level. It is also possible to add other environmental sensors.

In each of the embodiments shown above, the judgment made by the environment judgment unit 2 was in three stages: energy saving mode, normal mode, and open mode. However, it is not necessarily limited to these three stages, and energy saving mode is You can increase the number of stages by increasing the number of types or more. In automatic door control equipment that can adjust both door opening/closing speed and door opening/closing stroke,
In the case where the number of judgment stages of the environment judgment unit 2 is increased by setting two or more types of energy saving modes as described above, a method of simultaneously adjusting the door opening/closing speed and the door opening/closing stroke in each energy saving mode,
Another method is to adjust the door opening/closing speed in the first energy saving mode, and in the next energy saving mode, adjust the door opening/closing stroke while keeping the door opening/closing speed in the first energy saving mode. There is a method in which the stroke is adjusted alternately for each stage of judgment by the environment judgment section 2, and this method is possible by determining the door opening/closing speed and the output order of the door opening/closing stroke within the command section. Another possible method is to make the judgment by the environment judging section 2 stepless. For example, when the environment judgment unit 2 makes an environment judgment based on the temperature difference between the inside and outside of the automatic door, the environment judgment information sent to the command unit is sent to the outdoor temperature detector 1.
Based on the analog value, the command section instructs the door opening/closing speed and door opening/closing stroke to the door opening/closing control section steplessly. . In this way, as the temperature difference between the inside and outside of the automatic door increases, the door opening/closing speed can be gradually increased, and the door opening/closing stroke can be gradually decreased in a stepless manner.

In addition, when an automatic/manual changeover switch is provided in the automatic door control device according to the present invention that automatically adjusts the door opening/closing speed or door opening/closing stroke depending on the environment inside and outside the automatic door, and the switch is switched to automatic, the automatic door control device according to the present invention It is also possible to perform the function of an automatic door control device and, when switched to manual, to adjust the door opening/closing speed and door opening/closing stroke using a conventional selection switch or volume.

As is clear from the above explanation, if each automatic door control device according to the present invention is used, the opening/closing speed of the door can be adjusted automatically according to the environment inside and outside the automatic door, without any effort on the part of the user. It is possible to adjust the opening/closing speed and door opening/closing stroke to the optimal setting values, and to automatically and efficiently obtain effects such as suppressing deterioration of air conditioning efficiency and suppressing bad outdoor environments (outdoor noise, strong outdoor winds, etc.) from entering indoors. Can be done. An automatic door control device that can adjust both the door opening/closing speed and the door opening/closing stroke is more effective than an automatic door control device that adjusts only the door opening/closing speed, as it can obtain each of the above-mentioned effects more effectively.
