Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an automatic door installed in a building such as a building.

[0002]

2. Description of the Related Art When opening / closing an automatic door, the opening time of the door should be set longer than usual in order to prevent a decrease in the air conditioning effect of the indoor air conditioner during summer / winter, etc. Either shorten it or make the open area of the door smaller than usual. As a method to shorten the opening time of the door than usual,
A method of increasing the door opening / closing speed can be cited, while a method of reducing the opening area of the door includes a method of reducing the door opening / closing stroke. Conventionally, in this type of automatic door control device, the adjustment of the door opening / closing speed and the adjustment of the door opening / closing stroke are artificially performed by digital adjustment by a selection switch or the like or analog adjustment by a volume or the like. For example, when the user determines that the temperature difference between the outdoor and the indoor has increased during the air conditioning in the summer or winter, the door opening / closing speed is increased or the door opening / closing stroke is increased by adjusting the selection switch or the volume. It was made small to suppress the reduction of the air conditioning effect in the room.

[0003]

However, when the door opening / closing speed or the door opening / closing stroke is artificially set by the selection switch or the volume as described above, it takes a lot of time and effort for the user to set it. The reference of the door opening / closing speed and the door opening / closing stroke depends on the feeling of the user who makes the adjustment, and is not necessarily set optimally, and the temperature change from morning to noon to evening, etc. It was virtually impossible to adjust the set value according to the environment that changes with time.

The present invention has been made in view of the above circumstances, and independently sets two setting elements of a door opening / closing speed and a door opening / closing stroke according to the environment inside and outside the automatic door.
Alternatively, it is a technical subject to provide an automatic door control device having a function capable of automatically adjusting both of them to an optimum set value.

[0005]

[Means for Solving the Problems] As a concrete means for achieving the above-mentioned technical problems, an environment detector for detecting two or more different environments is installed inside or outside an automatic door or both of them. And a storage unit that stores a reference value corresponding to each data of the environment detector and a door opening / closing speed, or command data of a door opening / closing speed and a door opening / closing stroke,
An environment determination unit that determines an optimum environment mode based on at least two or more different environment data from the environment detectors that detect the different environments and a reference value of the storage unit, and the environment determination unit. And a command unit that selects command data in the storage unit based on the environmental mode output from the device and outputs the command data to the door opening / closing control unit.

[0006]

According to the above technical means, two or more different real environments such as the outdoor temperature, the outdoor humidity, the indoor temperature, and the indoor humidity are detected by the environment detector, and each data indicating each detected environment is detected. Is sent to the environment judgment section. On the other hand, the storage unit stores a reference value corresponding to each of the data, and the reference value is provided to the environment determination unit. Then, the environment determination unit sends the 2 sent from the environment detector.
Based on the different actual environments described above and the reference value provided from the storage unit, the optimum environment determination mode is determined,
This judgment result is sent to the command unit.

Further, the storage unit stores command data for only the door opening / closing speed or command data for both the door opening / closing speed and the door opening / closing stroke, and this command data is provided to the command unit. Therefore, the command unit selects the command data provided from the storage unit based on the optimum environment mode sent from the environment determination unit. Then, the selected command data is output to the door opening / closing control unit, and as a result, the door opening / closing operation is automatically controlled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic door control device according to the present invention will be described below with reference to the drawings. First, an embodiment in which only the door opening / closing speed is adjusted will be described with reference to FIG. 1. In this embodiment, as the environment detector 1, for example, an outdoor temperature detector 1a, an outdoor humidity detector 1b, and an outdoor wind speed are used. The detector 1c, the outdoor noise detector 1d, the indoor temperature detector 1e, and the indoor humidity detector 1f are installed individually or in combination inside and outside the automatic door, and the environment detector 1 such as 1a to 1f is installed in the environment determination unit 2. It is connected. The environment determination unit 2 is connected to the command unit 3, and the environment determination unit 2 and the command unit 3 are both connected to the storage unit 4. The command unit 3 further includes a door opening / closing control unit 5
An open timer circuit 6, a door position detection unit 7, a speed detection unit 8 and the like are connected to the door opening / closing control unit 5,
Further, the door opening / closing control unit 5 is connected to the drive circuit 9.
Further, the open timer circuit 6 is connected to a passing body detection unit 10 that detects a passing body that is about to enter or leave.

Next, the operation of the block circuit diagram of FIG. 1 configured as described above will be described. Environment detector 1
Outputs the measured data to the environment determination unit 2, and the environment determination unit 2 outputs at least two or more data of the respective data input from the environment detector 1 and the reference value provided from the storage unit 4. By comparing with, the optimum environment mode such as the energy saving mode, the normal mode, and the open mode is determined, and the determination is given to the command unit 3 as information. Further, the environment judging unit 2 can output each data from the environment detector 1 to the display unit 2a and display it on the monitor.

The command unit 3 inputs command data of the door opening / closing speed corresponding to each of the above modes from the storage unit 4, and among these command data, command data suitable for the information given from the environment judging unit 2 is used. A command for a certain door opening / closing speed is sent to the door opening / closing control unit 5.

The door opening / closing control unit 5 arbitrarily sets a normal speed (for a command of the door opening / closing speed from the command unit 3 issued when the judgment of the environment judging unit 2 is in the normal mode). The drive circuit 9 is controlled to open and close the door at, for example, 0.3 m / sec), and the door opening / closing speed command from the command unit 3 issued when the judgment of the environment judging unit 2 is in the energy saving mode In order to shorten the opening and closing time of the door, the drive circuit 9 is controlled to open and close the door at a speed (for example, 0.6 m / sec) faster than the normal speed, and the judgment of the environment judging section 2 is the open mode. In response to a command from the command unit 3 issued in some cases, the drive circuit 9 is controlled so that the door is normally opened.

That is, when the judgment of the environment judging unit 2 is the normal mode or the energy saving mode, the door opening / closing control unit 5 outputs from the open timer circuit 6 output based on the detection signal from the passing object detection unit 10. Alternatively, the stop / operation command section 5a in the door opening / closing control section 5 operates in response to a closing signal and operates in response to a command of the door opening / closing speed sent from the command section 3, so that the command speed in each of the normal mode and the energy saving mode is set. A corresponding operation command of a predetermined speed is output to the calculation unit 5b in the door opening / closing control unit 5.

In this calculation unit 5b, the stop / operation command unit
The predetermined speed commanded from 5a is compared with the momentary door speed data from the speed detection unit 8, and an operation command is issued so that the deviation value of the speed becomes 0. The forward / reverse rotation output unit in the door opening / closing control unit 5
5c, and the stop / operation command section 5a sends a forward or reverse command to the forward / reverse rotation output section 5c based on the open or close signal from the open timer circuit 6, and the forward / reverse rotation output section 5c. Sends an open or close control signal to the drive circuit 9 on the basis of an operation command based on the speed deviation value and a command for forward or reverse rotation.

The stop / operation command section 5a receives a signal when the door reaches the cushion position by the door position detection section 7 and sends a cushion command to the forward / reverse rotation output section 5c to open or close the door. Forward / reverse rotation output section 5c
Send a command to stop the operation.

However, the method of controlling the drive circuit 9 by the door opening / closing control unit 5 shown here is merely an example, and the door opening / closing control unit 5 is used.
The contents of are not limited to those described above and shown in FIG. 1, and the door opening / closing speed can be adjusted according to the command for each mode sent from the command unit 3 to the door opening / closing unit 5. Anything is fine.

Next, an embodiment in which the door opening / closing speed and the door opening / closing stroke are adjusted will be described with reference to FIG.
As the environment detector 1, the outdoor temperature detector 1a, the outdoor humidity detector 1b, the outdoor wind speed detector 1c, the outdoor noise detector 1d, and the indoor temperature detection, as in the case of adjusting only the door opening / closing speed described above. The device 1e and the indoor humidity detector 1f are installed individually or in combination inside and outside the automatic door, and these environment detectors 1, for example, 1a to 1f are connected to the environment determination unit 2. A storage unit 4 is connected to both the environment determination unit 2 and the command unit 3 '. The command section 3 ′ is further connected to the door opening / closing control section 5 ′ with two kinds of connecting lines for door opening / closing speed and door opening / closing stroke, and the door opening / closing control section 5 ′ has an open timer circuit 6, The door position detector 7 and the speed detector 8 are connected. And
The door opening / closing control unit 5 ′ is further connected to the drive circuit 9.
Further, the open timer circuit 6 is connected with a passing body detection unit 10 for detecting a passing body that is about to enter or leave.

Next, the operation of the block circuit diagram shown in FIG. 2 will be described. The environment detector 1 outputs each measured data to the environment determination unit 2, and the environment determination unit 2 provides from the storage unit 4 and at least two data of the respective data input from the environment detector 1. The optimum environmental mode such as the energy saving mode, the normal mode, and the open mode is determined by comparing with the reference value that is set, and the determination is given to the command unit 3 ′ as information. Further, the environment judging unit 2 can output each data from the environment detector 1 to the display unit 2a and display it on the monitor.

The command unit 3 inputs the command data of the door opening / closing speed and the door opening / closing stroke corresponding to each mode from the storage unit 4, and conforms to the information given from the environment judging unit 2 in each command data. The door opening / closing speed and the door opening / closing stroke command, which are the command data, are sent to the door opening / closing control unit 5 ′.

The door opening / closing control section 5'is arbitrarily set with respect to the door opening / closing speed and the door opening / closing stroke command from the command section 3'issued when the judgment of the environment judging section 2 is in the normal mode. 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, opening / closing stroke up to the fully open position), and the environment determination unit 2 makes a determination in the energy saving mode. In response to the command of the door opening / closing speed and the door opening / closing stroke from the command unit 3 ′ issued in the case of, in order to shorten the door opening / closing time, a speed higher than the normal speed (for example, 0.6 m / sec) and 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) in order to reduce the opening area of the door.

That is, when the judgment of the environment judging section 2 is the normal mode or the energy saving mode, the door opening / closing control section 5'is output from the open timer circuit 6 which is output based on the detection signal from the passing object detection section 10. When the door open / close control unit 5 ′ operates by receiving an open or close signal, the first arithmetic circuit 5
The door opening / closing stroke instructed from the above-mentioned command unit 3'is compared with the data of the momentary door position sent from the door position detection unit 7 by d ', and the calculated value is stopped / operation command unit 5a'. I am sending it to.

The stop / operation command section 5a 'includes a first arithmetic circuit 5a.
Based on the calculated value sent from d ', corresponding to each command opening and closing stroke in normal mode and energy saving mode,
Send the door operation command to the forward / reverse rotation output section 5c ', and forward / reverse rotation output section
5c 'sends an operation signal to the drive circuit 9 according to this command.
At the same time, the stop / operation command section 5a 'sends an operation command of a predetermined speed corresponding to each command speed in the normal mode and the energy saving mode to the second arithmetic circuit 5b' in response to the door opening / closing speed command from the command section 3 '. ing.

The second arithmetic circuit 5b ', which has received the data of the predetermined speed designated by the stop / operation command section 5a' and the door speed from the speed detection section 8, operates so that the deviation value becomes zero. Send a command to the forward / reverse rotation output section 5c ', and
The operation command section 5a 'sends a normal rotation 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 the forward / reverse rotation output section 5c 'outputs the second rotation signal.
An open or close control signal is sent to the drive circuit 9 based on the operation command based on the deviation value of the speed sent from the arithmetic circuit and the forward or reverse command sent from the stop / operation command unit 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 'sends a command for cushion operation to the forward / reverse rotation output section 5c'. When the door reaches the open position or the fully open position corresponding to the opening / closing stroke position commanded by the command unit 3 ', the calculated value from the first calculation circuit 5d' sent to the stop / operation command unit 5a 'is 0. Then, 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 unit 5c '. When a command in the opening mode is sent from the command unit 3 ′, the door opening / closing control unit 5 ′ controls the drive circuit 9 so that the door is always open.

However, the door opening / closing control unit 5'shown in FIG. 2 is an example of the control method of the drive circuit 9, and the door opening / closing control unit required for the present invention is the door opening / closing control unit from the command unit 3 '. As long as the door opening / closing speed and the door opening / closing stroke can be adjusted according to the command for each mode sent to the unit, the present invention is not limited to the embodiment.

In the above-mentioned two embodiments, the judgment method of the environment judgment unit 2 will be described with an example.
For example, when a temperature difference occurs between the inside and outside of the automatic door due to air conditioning by an air conditioner or the like in the summer and winter, the environment determination unit 2 is stored in the storage unit 4.
The standard value of the difference between the outdoor temperature and the indoor temperature given to the room 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 detector 1a and the data sent from the indoor temperature detector 1e. When the difference exceeds the reference value of 5 ° C, the environment judgment unit 2 instructs the command unit 3 to shorten the door opening / closing time or reduce the door opening area to suppress the reduction of the air conditioning effect. , When the environmental judgment of the energy saving mode is sent as information, and the temperature difference between the inside and outside of the automatic door obtained as the difference between the data sent from the outdoor temperature detector 1a and the indoor temperature detector 1e is less than the reference value of 5 ° C, Environment judgment unit 2 is command unit 3
Send the normal mode environment judgment to.

With respect to the environment detector 1 shown in the embodiment, the data from the outdoor temperature detector 1a is 5 ° C. or less in winter as an example of the case where the environment judging section 2 makes the environment judgment in the energy saving mode. In some cases, such as during the rainy season, air conditioning by an air conditioner allows outdoor humidity detector 1b and indoor humidity detector 1f.
The difference between the humidity inside and outside the automatic door, which is obtained as the difference in the data of
If the data from the outdoor wind speed detector 1c is 10 m / sec or more during a typhoon, etc., or if the data from the outdoor noise detector 1d is increased during construction or due to increased traffic
For example, when it becomes 50 dB or more.

Further, as an example of the case where the environment judging section 2 makes the environment judgment in the open mode, there is a case where it is necessary to open the door in order to secure an evacuation passage in case of a fire. It is possible that the data from 1e exceeds 50 ° C. The environment judgment of the environment judgment unit 2 except when making the environment judgment in the energy saving mode or the open mode is the normal mode.

However, the judgment criteria for each mode of the environment judgment section 2 shown here, that is, the reference value given from the storage section 4, is
This is merely an example, and it can be changed as necessary, and the type of determination of the indoor / outdoor temperature difference, the humidity difference, etc. is not limited to the above. Also, the type of the environment detector 1 is not limited to the above-mentioned embodiments, and may be smaller than that of each embodiment, for example, an air pollution degree detector or the like for detecting the degree of outdoor air pollution. It is also possible to add environment detectors other than the above.

In each of the above-described embodiments, the judgment made by the environment judgment unit 2 is made in the energy saving mode, the normal mode,
Although there are three stages of the open mode, it is not necessarily limited to these three stages, and an energy saving mode in the case where one of the plurality of data from the environment detector 1 exceeds a reference value, The number of stages can be increased by, for example, setting the energy saving mode to be different when two or more data exceed the reference value.

In the automatic door control device capable of adjusting both the door opening / closing speed and the door opening / closing stroke, if the number of judgment steps of the environment judging section 2 is increased by setting two or more energy saving modes as described above, In the energy saving mode, the door opening / closing speed and the door opening / closing stroke are adjusted at the same time, and as another method, the door opening / closing speed is adjusted in the first energy saving mode, and in the next energy saving mode, the door opening / closing speed in the first energy saving mode is adjusted. There is a method of alternately adjusting the door opening / closing speed and the door opening / closing stroke for each judgment step of the environment judging unit 2 such as adjusting the door opening / closing stroke. This is possible by determining the output order.

A method of making the judgment of the environment judging section 2 stepless is also conceivable. For example, when the environment determination unit 2 determines the environment based on the temperature difference and the humidity difference between the inside and outside of the automatic door, the information about the environment determination is used as the outdoor temperature detector 1a and the indoor temperature detector 1e.
The difference between the data sent from and the outdoor humidity detector 1b and the difference between the data sent from the indoor humidity detector 1f is output to the command unit as an analog value with respect to the added value or the average value, and the command unit,
The door opening / closing speed and the door opening / closing stroke are commanded steplessly to the door opening / closing control unit based on the analog amount. With this configuration, the door opening / closing speed can be gradually increased and the door opening / closing stroke can be gradually reduced as the temperature difference and humidity difference inside and outside the automatic door increase.

According to the present invention, an automatic / manual changeover switch is provided in the automatic door control device for automatically adjusting the opening / closing speed or door opening / closing stroke of the automatic door according to the environment inside or outside the automatic door. When the function of the automatic door control apparatus according to the present invention is fulfilled and the mode is switched to manual, a method of adjusting the opening / closing speed or the door opening / closing stroke of the door by a conventional selection switch or volume is also possible.

[0033]

As is apparent from the above description, by using each automatic door control device according to the present invention, the automatic door control can be automatically performed according to the environment inside and outside the automatic door without the user's trouble. The opening / closing speed or the door opening / closing speed and the door opening / closing stroke can be adjusted to the optimum set values, and the effect of suppressing the reduction of the air conditioning effect and the invasion of bad outdoor environment (outdoor noise, outdoor strong wind, etc.) into the room is automatically achieved. It can be obtained efficiently. The automatic door control device capable of adjusting both the door opening / closing speed and the door opening / closing stroke is effective because it can obtain each of the above-mentioned effects more than the automatic door control device adjusting only the door opening / closing speed.
