Description

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

When air conditioning indoors in summer and winter, in order to prevent the effectiveness of the air conditioning from decreasing, and to prevent bad outdoor environments such as noise and strong winds from entering the room, the open area of the door should be made larger than usual. In this case, (1) the purpose can be achieved by reducing the opening/closing stroke of the door. Conventionally, in this type of automatic door control device, the door opening/closing stroke has been manually set by digital adjustment using a selection switch or the like, or analog adjustment using a volume, limit switch, or the like. For example, if the user determines that the temperature difference between indoors and outdoors has become large during indoor air conditioning in summer or winter, the user can adjust the selection switch, volume, limit switch, etc. to set the door opening/closing stroke to a smaller value, By reducing the open area, the indoor air conditioned air is prevented from being discharged outdoors to prevent the air conditioning effectiveness from decreasing.

However, when the opening/closing stroke of the door is artificially set using a selection switch, volume, limit switch, etc. as described above, it takes time for the user to set it, and the standard for the door opening/closing stroke to be set is The settings depend on the senses of the user who makes the adjustments, and the settings are not necessarily optimal, and may change from hour to hour, such as the temperature change from morning to afternoon (2). It was virtually impossible to adjust the settings to suit the environment.

This invention was made in view of the above circumstances, and provides an automatic door control device that has a function of automatically setting the opening/closing stroke of the door to the optimum stroke according to the internal and external environments of the automatic door. This is what we provide. The features of this automatic door control device include an environment detector installed inside and outside the automatic door, an environment judgment section that judges the environment based on the data measured by the environment sensor, and an environment judgment section that judges the environment based on the data measured by the environment sensor. A door having a command section that commands a door opening/closing stroke according to the environment in which the door is to be opened, a storage section that provides setting data to the environment judgment section and the command section, and a function of adjusting the door opening/closing stroke according to the commands of the command section. It has an opening/closing control section.

An example of this will be described below based on the block circuit shown in FIG.

In this embodiment, the environmental detectors 1 include, for example, an outdoor temperature sensor 1a, an outdoor humidity sensor (3) 1b, an outdoor wind speed sensor 1c, an outdoor noise detector 1d, an indoor temperature sensor 1e, and an indoor humidity sensor. Detectors 1f are installed singly or in combination inside and outside the automatic door, and these environment detectors 1, for example, the above-mentioned 1a to 1f, are connected to the environment determining section 2.

The environment judgment section 2 is connected to a command section 3, and a section a 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, an open timer circuit 6, a door position detection unit 7, etc. are connected to the door opening/closing control unit 5, and the door opening/closing control unit 5 is further connected to a drive circuit 9. ing.

Also, connected to the open timer circuit 6 is a passing body detector 10 that detects passing bodies attempting to enter or exit.

Next, the operation of the block circuit diagram of FIG. 1 configured 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 outputs each of the data input from the environment sensor 1 and the setting data provided from section 1.9 section 4. By comparing the reference values as
is given as information. Further, each data from the environment detector 1 can be outputted to the display section 2a and displayed on a monitor.

The command unit 3 inputs the command data for each mode as setting data from the storage unit 4, and in the command data, the door opening/closing stroke which is the compatible command data is inputted from the information G given from the environment judgment unit 2. This command is sent to the door opening/closing control section 5.

The door opening/closing control unit 5 responds to the door opening/closing stroke command issued from the command unit 3 when the judgment of the environment determining unit 2 is in the normal mode by executing an arbitrarily set normal opening/closing stroke (for example, full open). The drive circuit 9 is controlled to open and close the door according to the opening/closing stroke up to the position (opening/closing stroke), and in response to the door opening/closing stroke command issued from the command unit 3 when the environment judgment unit 2 determines that the energy saving mode is selected. controls the drive surface (5) to open/close the door with a smaller opening/closing stroke (for example, an opening/closing stroke to a half-open position) than the normal opening/closing stroke in order to reduce the opening area of the door, and In response to a command from the command unit 3 issued when the environment determination unit 2 determines that the door is in the open mode, the drive circuit 9 is controlled to keep the door open at all times.

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 the detection signal from the pedestrian detector 10. It operates in response to

In the door opening/closing control section 5, the arithmetic circuit 5a compares and calculates the door opening/closing stroke commanded from the command section 3 and the momentary door position data sent from the door position detection section 7, and calculates the calculated value. is sent to the stop/operation command unit 5b, and based on this calculated value, the stop/operation command unit 5b responds to each command opening/closing stroke in the normal mode and energy saving mode.For example, when the calculated value becomes O, the door position is changed to the command unit. If the calculated value is other than 0, it is determined that the door position has not reached the door opening/closing stroke and the operation command is issued in the forward or reverse direction. At the same time, when the signal from the O(6)-punch timer circuit 6 is an open signal, a command for forward rotation is sent to the output section 5c, and when the signal is a close signal, a command for reverse rotation is sent to the forward/reverse output section 5c. . This forward/reverse output section 5c sends an open/close control signal and a stop signal to the drive circuit 9 based on a door operation command or operation stop command sent from the stop/operation command section 5b, and a forward or reverse rotation command. are sending.

That is, the open signal from the open timer circuit 6 sends a close control signal to the drive circuit 9 to open the door, and the door position detection section 7
When the door reaches the open position corresponding to the door opening/closing stroke command from the command unit 3 in response to a door position detection signal from The circuit 9 is stopped to stop the door in the predetermined open position.

Thereafter, when the passing object is no longer detected by the passing object detection section 6, the open timer circuit 6 sends a close signal to the stop/operation command section 5b after the preset holding time of the passing object detection signal has passed. Specified by this close signal
An operation command and a reverse command are sent from the operation command section 5b to the forward/reverse rotation output section 5c, and based on these commands (7), a closing control signal is sent from the forward/reverse rotation output section 5c to the drive circuit 9 to close the door. Furthermore, when the door reaches the fully closed position or the cushion position, it is detected by the door position detection section 7, and the detection signal is sent to the stop/operation command section 5b, and based on this detection signal, the stop 1-/operation is executed. An operation stop command and a cushion command are sent from the command section 5b to the forward/reverse rotation output section 5c.

The automatic door control device using the block circuit shown in Figure 1 is
The opening area of the door is adjusted by setting the door opening/closing stroke according to the environment around the door as described above. However, the method of controlling the drive circuit 9 by the door opening/closing control section 5 shown here is only an example, and the contents of the door opening/closing control section 5 are not limited to those shown in the above description and figures, and the command section Any device may be used as long as it can adjust the door opening/closing speed i/loaf in response to the commands for each mode sent from the door opening/closing '+fa control section 3 to the door opening/closing '+fa control section 5.

Next, to provide a more detailed explanation of the judgment method of the environment judgment unit 2 in the above operation contents, for example, when a temperature difference occurs between the inside and outside of the automatic door due to air conditioning by an air conditioner in summer and winter (8), In Part 9 4, the reference value for the difference between the outdoor temperature and the indoor temperature given to the environment judgment unit 2 is set to 5°C, and the temperature inside and outside the automatic door obtained as the difference between the data actually sent from the outdoor temperature sensor 1a is set as 5°C. When the temperature difference exceeds the standard value of 5°C, the environment judgment unit 2 instructs the command unit 3 to select an energy saving mode environment judgment in order to reduce the open area of the door and prevent a decrease in air conditioning effectiveness. The outdoor temperature sensor 1a and the indoor salinity sensor Bl are sent as information.
If the temperature difference between the inside and outside of the automatic door obtained as the difference between the data sent from
sends the normal mode environment judgment to the command unit 3.

Below, regarding the environment detector 1 shown in the example, environmental judgment 2
For example, when the data from the outdoor temperature sensor 1a falls below 5°C during the winter, etc., or when the data from the outdoor temperature sensor 1b is set by the air conditioner due to air conditioning during the rainy season, etc. When the humidity difference between the inside and outside of the automatic door obtained as the difference in data from the indoor humidity detector 1f becomes 10% or more, or when the data from the outdoor wind speed detector 1c becomes 10 m/5ec (9) or more during a typhoon, etc. The data from the outdoor noise detector 1d may be 50 dB due to construction work or an increase in vehicle speed.
Examples include cases where the above occurs. Further, an example of a case where the environment judgment unit 2 makes an environment judgment of the open mode is when it is necessary to open the door to secure the MH passage in the event of a fire. It is possible that the data exceeds 50°C. The environment judgment section 2 makes environmental judgments in the normal mode except when making the environmental judgments for the energy saving mode or the open 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 humidity difference, humidity difference, etc. are not limited to the above. Furthermore, the types of environment detectors 1 are not limited to those in the embodiments, and may be smaller than those in the embodiments. It is also possible to add a detector.

In the embodiment shown above, the judgment indicated by the environment judgment unit 2 (10) was in three stages: energy saving mode, normal mode, and open mode, but it is not necessarily limited to these three stages; The number of stages can be increased by using two or more types. Another possible method is to make the judgment by the environment judging section 2 stepless. For example, when the environment judgment unit 2 makes a judgment based on the temperature difference between the inside and outside of the automatic door, the environment judgment information sent to the command unit 3 corresponds to the difference between the data sent from the outdoor temperature sensor 1a and the indoor temperature sensor 1e. The signal is sent as an analog quantity, and the command unit 3 instructs the door opening/closing stroke to the door opening/closing control unit 5 steplessly based on the analog quantity. If you do this,
The opening/closing stroke of the door can be gradually reduced in inverse proportion to the temperature difference between the inside and outside of the automatic door.

The automatic door control device according to the present invention, which automatically adjusts the opening and closing speed of the door depending on the environment inside and outside the automatic door, is provided with an automatic/manual changeover switch, and when switched to automatic, the automatic door control according to the present invention When the function of the device is fulfilled and it is switched to manual mode, it is also possible to use the conventional method (11) in which the opening/closing stroke of the door is adjusted using a selection switch or a volume control.

As is clear from the above explanation, if the automatic door control device according to the present invention is used, the opening/closing stroke of the door can be automatically optimized according to the environment inside and outside the automatic door without any effort on the part of the user. The stroke can be adjusted automatically and efficiently to prevent deterioration of the air conditioning effect and prevent bad outdoor environments (outdoor noise, strong outdoor wind, etc.) from entering the room.
