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, the purpose can be achieved by reducing the opening/closing stroke of the door. Conventionally, in this type of automatic door control device, the setting of the door opening/closing stroke is digitally adjusted using a selection switch, etc.
Or, it was done artificially by analog adjustment using volume, limit switches, etc. 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 set the door opening/closing stroke to a smaller value by adjusting the selection switch, volume, limit switch, etc. to reduce the opening area of the door. By making it smaller, the air conditioned inside the room is prevented from being discharged outside to prevent the air conditioning effectiveness from decreasing.

However, when the opening/closing stroke of the door is artificially set using the 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 sense of the user who makes the adjustment, and the settings are not necessarily optimal, and the environment changes hourly, such as when the temperature changes from morning to noon to evening. In fact, it was almost impossible to adjust the setting values accordingly.

The present 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 feature of this automatic door control device is that an environmental detector is installed on the inside or outside of the automatic door, or both, in the automatic door that opens and closes the entrance to the building. An environment judgment unit is provided to judge the environmental state based on the normal mode and the normal mode in which the environment judgment unit controls the opening and closing of the door that reciprocates the full stroke between the fully open and fully closed positions of the entrance. An energy-saving mode that controls the opening and closing of a door that reciprocates with a stroke smaller than the full stroke between the inner position and the fully closed position, and the opening and closing control of the door that is kept in the full stroke state of the fully open position of the doorway. A command section is provided for setting an open mode in which the environment is determined, and a command section is provided for instructing each of the modes according to the environmental state determined by the environment determination section, and a storage section is provided for providing setting data to the environment determination section and the command section. , a door opening/closing control section is provided for controlling door opening/closing according to each of the modes according to mode commands from the command section. The ``environment'' of an environmental sensor, etc., as referred to here, refers to indoor and outdoor temperature, humidity, etc.
Can be detected by human five senses such as wind speed and noise, and
These are things that make people feel emotions such as pleasure and discomfort.

One embodiment of this will be explained 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 1b, an outdoor wind speed sensor 1c, and an outdoor noise detector 1.
d. An indoor temperature sensor 1e and an indoor humidity sensor 1f are installed either singly or in combination inside and outside the automatic door, and these environmental sensors 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 storage section 4 is connected to both the environment judgment section 2 and the command section 3. Command section 3
is further connected to the door opening/closing control section 5, and the door opening/closing control section 5 has an open timer circuit 6 and a door position detection section 7.
etc. are connected, and the door opening/closing control section 5 is connected to a drive circuit 9.
is connected to. Also, connected to the open time 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 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 inputted from the environment sensor 1 and the reference as setting data provided from the storage section 4. By comparing the values, you can select between energy saving mode, normal mode and
The environment such as open mode is determined and the determination is given to the command section 3 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 receives the setting data from the storage unit 4,
The command data for each mode is input, and among the command data, a door opening/closing stroke command, which is command data that matches the information given from the environment determining 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 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 opens and closes the door with the opening/closing stroke up to the position
In addition, in response to the door opening/closing stroke command from the command unit 3 issued when the environment determination unit 2 determines that the energy saving mode is selected, the normal The drive circuit 9 is controlled to open and close the door with an opening/closing stroke smaller than the opening/closing stroke (for example, an opening/closing stroke to a half-open position), and the command section 3 is issued when the judgment of the environment judgment section 2 is in the open mode. In response to commands from the driver, 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 a detection signal from the pedestrian detection unit 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. The calculated value is sent to the stop/operation command unit 5b, and based on this calculated value, the stop/operation command unit 5b adjusts the door position in response to each commanded opening/closing stroke in the normal mode and energy saving mode, for example, when the calculated value becomes 0. It determines that the door opening/closing stroke commanded by the command unit 3 has been reached and issues an operation stop command, and when the calculated value is other than 0, it determines that the door position has not reached the door opening/closing stroke and issues an activation command. When the signal from the open timer circuit 6 is an open signal, a forward rotation command is sent to the forward/reverse rotation output section 5c, and when the signal is a close signal, a reverse rotation command is sent to the forward/reverse rotation output section 5c. This forward/reverse rotation output section 5c is the stop/operation command section 5b.
An open or close control signal and a stop signal are sent to the drive circuit 9 based on a door operation command or an operation stop command sent from the door, and a forward rotation or reverse rotation command.

That is, an open control signal is sent to the drive circuit 9 based on the open signal from the open timer circuit 6, and the door is opened.
When the door receives the door position detection signal from the door position detection section 7 and reaches the open position corresponding to the door opening/closing stroke command from the command section 3, the stop/operation command section 5b instructs the forward/reverse rotation command section 5c to stop the operation. A command is sent to stop the drive circuit 9 and stop the door at a predetermined open position. After that, when a passing object passes and is no longer detected by the passing object detection section 6, the open timer circuit 6 sends a close signal to the stop/activation command section 5b after the preset holding time of the passing object detection signal has passed. This close signal sends an operation command and a reverse rotation command from the designation/operation command section 5b to the forward/reverse rotation output section 5c.
Based on these commands, a closing control signal is sent from the forward/reverse output section 5c to the drive circuit 9 to close the door. 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 the stop/operation command section 5b receives the detection signal based on this detection signal. 5b sends an operation stop command and a cushion command to the forward/reverse rotation output section 5c.

The automatic door control device using the block circuit shown in FIG. 1 attempts to adjust the open area of the door 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 just 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 3 to the door opening/closing control section 5
Any device that can adjust the door opening/closing stroke in response to the commands sent to each mode for each mode will suffice.

Next, in the above operation content, the environment judgment unit 2
To give a more detailed explanation of how to judge,
For example, when a temperature difference occurs between the inside and outside of an automatic door due to air conditioning by an air conditioner in summer and winter, the storage unit 4 sets the reference value for the difference between the outdoor temperature and the indoor temperature to be given to the environment judgment unit 2 as 5°C. When the temperature difference between the inside and outside of the automatic door, obtained as the difference between the data actually sent from the outdoor temperature sensor 1a, exceeds the reference value of 5°C, the environment judgment unit 2 instructs the command unit 3 to determine the open area of the door. In order to prevent the deterioration of the air conditioning effect by reducing the energy saving mode, the environmental judgment of the energy saving mode is sent as information, and the temperature inside and outside of the automatic door, which is obtained as the difference between the data sent from the outdoor temperature sensor 1a and the indoor temperature sensor 1e, is transmitted as information. When the temperature difference is less than the reference value of 5° C., the environment judgment unit 2 sends the normal mode environment judgment to the command unit 3. Hereinafter, regarding the environment detector 1 shown in the embodiment, as an example of the case where the environment judgment unit 2 makes an environment judgment of the energy saving mode, there is a case where the data from the outdoor temperature sensor 1a falls below 5 degrees Celsius in winter etc. When the humidity difference between the inside and outside of the automatic door, which is obtained as the difference between the data of the outdoor humidity detector 1b and the indoor humidity detector 1f due to air conditioning during the rainy season, becomes 10% or more, or during typhoons, etc., outdoor wind speed is detected. Examples include when the data from the outdoor noise detector 1c becomes 10 m/sec or more, or when the data from the outdoor noise detector 1d becomes 50 dB or more due to construction work or an increase in car traffic. Further, an example of a case where the environment judgment unit 2 makes an environment judgment of the open mode is a case where it is necessary to open a door to secure an evacuation route in the event of a fire.
It is possible that the data from the temperature exceeds 50℃.
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 only examples and can be changed as necessary, and may vary depending on the temperature difference between indoors and outdoors. The types of judgments such as humidity differences 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 environment judgment unit 2
The judgment indicated by is energy saving mode, normal mode,
There were three stages of open mode, but these three stages are not necessarily the same.
The number of stages is not limited, and the number of stages can be increased by providing two or more types of energy saving modes. 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 environmental judgment information sent to the command unit 3 is based on the difference between the data sent from the outdoor temperature sensor 1a and the indoor temperature sensor 1e. The command unit 3 sends it as a corresponding analog quantity, and the command unit 3 controls the door opening/closing control unit 5 based on the analog quantity.
Then, the door opening/closing stroke is commanded steplessly. In this way, the opening/closing stroke of the door can be gradually reduced in inverse proportion to the increase in the temperature difference between the inside and outside of the automatic door.

The automatic door control device according to the present invention that automatically adjusts the opening/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, a conventional method of adjusting the opening/closing stroke of the door by means of a selection switch or a volume is also possible.

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.
