この発明は扉の開度を制御することができる駆
動装置を有する自動扉の駆動制御方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for controlling the drive of an automatic door having a drive device capable of controlling the degree of opening of the door.

いことではなかつた。 Conventional automatic door drive control methods issue an opening command to the drive device when either an internal detection switch installed on the inside of the door or an external detection switch installed on the outside of the door detects a passing object. The door is now fully open. However, in this conventional control method, even if the area near the door is crowded and the door needs to be opened wide, or conversely, there is only one passerby and the door needs to be opened narrowly, the opening command cannot be issued. There is only one type of door, so when a passing object is detected, the door always opens fully to a preset opening degree. For this reason, for example, in large automatic doors with a full opening stroke installed at the entrances and exits of buildings with large frontages, the door opens fully even when there is only one passerby, opening more than necessary. This resulted in air conditioning loss, which was not desirable for energy conservation.
この発明はこのような事情に鑑みなされたもの

ある。 This invention was made in view of the above circumstances, and when the area near the door is crowded and there are many pedestrians passing through the doorway, the opening of the door is widened to make it easier to pass through. An object of the present invention is to provide a drive control method for an automatic door that prevents air conditioning loss by reducing the opening degree of the door when there are few objects passing through the door.

ある。 In order to achieve this object, the present invention is characterized by providing, in addition to the conventional inside detection switch and outside detection switch, a door opening detection switch that detects objects passing through the door opening. The system uses a combination of detection signals from the detection switch, outside detection switch, and door opening detection switch to determine the traffic condition and control the drive device to set the door to an appropriate opening degree.

合つた方式により各位置を検知すればよい。 In FIG. 1, two automatic doors 1a and 1b installed at the entrance of a building are driven by a drive device (not shown) in the door 8 to move away from each other to open the entrance. , conversely, move in the direction of approaching each other and close the entrance/exit. These two doors 1a,
An inner detection switch 2 consisting of a floor mat or the like for detecting objects passing through is provided inside the building than 1b, and an outside detection switch 3 consisting of a floor mat or the like for detecting objects passing through is provided on the outside thereof. Furthermore, a door opening detection switch 4 made of a phototube switch or the like is provided to detect objects passing through the openings of the two doors 1a and 1b. A closed position detection limit switch 5, which detects when the door 1a is in the fully closed position, is installed in the door 1, which is fixed to the building.
A predetermined opening position detection limit switch 6 detects when door a reaches a predetermined opening position smaller than a preset full open position, and detects when door 1a reaches a preset fully open position. Three types of detection limit switches are installed, including a fully open position limit switch 7. The above three types of detection limit switches can be installed only for the door 1a as in the embodiment, or conversely, only for the door 1b, or can be installed for both the doors 1a and 1b. ,
The detection signals of each detection limit switch according to 1b may be used in parallel, or in the case of a belt drive system, for example, a metal fitting attached to the belt may be used to set the detection limit switch at the position corresponding to each fully open, fully closed, and predetermined opening position. Various methods can be considered, such as detecting each position by operating a limit switch or the like, and each position may be detected using a method suitable for each automatic door.

2信号21が制御回路11に対して送られる。 FIG. 2 is a block diagram of the present invention which sends a door operation signal based on the detection signals of each detection switch and each detection limit switch described above to the control circuit 11 that controls the automatic door drive device 10. 12 in the figure is an OR circuit that inputs the detection signal of the inside detection switch 2 and the detection signal of the outside detection signal 3, and when either the inside or outside detection switch detects a passing object and issues a detection signal, The control circuit 1 uses the output as the first signal 13 that commands a predetermined opening degree.
Send to 1. Here, the detection signal of the door opening detection switch 4 can also be inputted to the OR circuit 12, and the first signal 13 is output even when the door opening detection switch 4 detects a passing body. By doing so, even if a passing object is not detected by either the inside or outside detection switch, the door will not close and pinch the passing object, and the door opening detection switch 4 will be activated as a safety switch. It can also serve as 14 is a self-holding circuit for the detection signal of the door opening detection switch 4, and after the doors 1a and 1b are in the open state and a passing object is detected by the door opening detection switch 4, the doors 1a and 1b are fully closed. The detection signal of the door opening detection switch 4 is held until the detection signal of the closed position detection limit switch 5 is received. The NOT circuit 15 is used to invert the presence or absence of the detection signal of the door opening detection switch 4 held as described above, and when there is no detection signal held in the self-holding circuit 14, the AND
An output signal is provided to circuit 16. The AND circuit 16 includes the inner detection switch 2, the outer detection switch 3, and the
When the output of the NOT circuit 15 is input and the above three types of outputs are present, that is, the inside and outside detection switches simultaneously detect a passing object, and the self-holding circuit 14 receives the detection signal of the door opening detection switch 4. When it is not held, outputs a second signal 17 instructing full opening,
The second signal 17 is sent to the control circuit 11. Next, 1
8 is a time counter circuit, which starts counting the time from that point on when the door opening detection switch 4 detects a passing body and outputs a detection signal, and starts counting again within the set time determined by the set time circuit 19. When the door opening detection switch 4 detects a passing object and outputs a detection signal, it outputs an output to the self-holding circuit 20. When the time set by the set time circuit 19 is exceeded, the timer is reset, and after being reset, the door opening is detected. Even if the detection signal from the detection switch 4 is received, the clock counter circuit 18 does not output any output. The output from the time counter circuit 18 is transmitted to the doors 1a and 1 by the self-holding circuit 20.
b is held until it reaches the full open position and is detected by the full open position detection limit switch 7, and while this is held, a second signal 21 instructing full opening is sent from the self-holding circuit 20 to the control circuit 11.

れている。 In this way, the control circuit 11 receives the first signal 13,
The driving of the automatic door drive device 10 is controlled by receiving the second signals 17 and 21, but if the second signals 17 and 21 and the first signal 13 are received at the same time, the second signal 17 and 21 is received.
Circuitry is included to prioritize signals 17 and 21. When the control circuit 11 receives the first signal 13, as shown in FIG. 3, the doors 1a and 1b reach a predetermined opening position smaller than fully open and receive a detection signal from the predetermined opening position detection limit switch 6. The drive device 10 is driven to open until then, and then the drive is stopped, and
When either the second signal 17 or 21 is received, the drive device 10 continues until the doors 1a, 1b reach the predetermined fully open position and receive the detection signal from the fully open position detection limit switch 7, as shown in FIG. The circuit structure is such that the drive is driven open and then the drive is stopped.

開駆動するようにしておくことも可能である。 Next, when the doors 1a and 1b are stopped at a predetermined opening position or when the doors 1a and 1b are stopped at a fully open position, the inside detection switch 2, the outside detection switch 3, and the door opening detection switch 4 are activated. When none of the three types of detection switches detect a passing body, it means that the signal 13 has disappeared. When the first signal 13 disappears, the second signal 17
Due to the nature of the OR circuit 12 that outputs 3 and the AND circuit 16 that outputs the second signal 17, the second signal 21 also disappears when the doors 1a and 1b reach the fully open position. Since it has disappeared, all door open signals to the drive device 10 have disappeared. When the first signal 12 disappears in this way, the drive device 10 starts to drive to close, and as shown in FIG. When received, the closing drive stops. Here, the first signal 1
2 disappears, the closing drive of the drive device 10 is not started immediately, but is started after a certain period of time.If there is always more than a certain amount of traffic, it is possible to close the door more than necessary. Effective in preventing opening and closing. Now, the drive device 10 is controlled by the control circuit 11 in this way, but as can be seen from the above, the drive device 10 does not receive the first signal 12 even when the doors 1a and 1b are stopped at the fully open position. Since doors 1a and 1b are not driven to close unless
does not move from the fully open position and stop at the predetermined opening position, but this means that the doors 1a and 1
This is to avoid giving a sense of fear due to the door starting to close.Furthermore, in consideration of this point, a memory section for the fully open state is provided in the control circuit 11, so that once the door is in the fully open position, It has a full open holding function that keeps the door in the fully open position as long as the signals (first and second signals) are input, and the first When the signal 13 and the second signals 17 and 21 enter the control circuit 11, it is also possible to unconditionally drive the opening toward the fully open position.

駆動を停止する。 In the case of one-way traffic as shown in Fig. 6, in which the object A passes through an automatic door installed at the entrance from the inside of the building to the outside, the object A is first detected by the inside detection switch 2, and at the same time As a door activation signal
The first signal 13 is passed through the OR circuit 12 to the control circuit 11.
The drive device 10 starts the opening drive. time
After To, the doors 1a and 1b reach a predetermined opening position and when detected by the predetermined opening position detection limit switch 6, the opening drive is stopped. The passing object A is then detected by the door opening detection switch 4 and the outside detection switch 3 in this order, and during this time the OR circuit 12 continues to output the first signal 13, so the doors 1a and 1b maintain a predetermined opening state. When the object A passes by and neither the inside/outside detection switch nor the door opening detection switch 4 detects the object, the first signal 13 disappears and the drive device 1
0 starts the closing drive, and if this time is t 1 , then time t 2
After =t 1 +To, the doors 1a and 1b are fully closed, detected by the closed position detection limit switch 5, and the drive device 10 stops the closing drive.

通過する間、扉1a,1bは前記片側通行の場
合と同じく所定開度位置状態のままである。 Similarly to the above case, in one-way traffic in which a passing object passes through an automatic door from the inside to the outside of a building, the object B is simultaneously activated by the inside detection switch 2 and the outside detection switch 3, as shown in Fig. 6. In the case where the object B is detected, the object B is always detected by the door opening detection switch 4 at time t3 before being detected by the outside detection switch 3, and the detection signal of the door opening detection switch 4 is transmitted at the time t. 3 then doors 1a, 1b
The signal is held in the self-holding circuit 14 until time t5 when it is fully closed, and no signal is input to the AND circuit 16 by the NOT circuit 15, so the period from time t3 to time t5 is within the holding period of the self-holding circuit 14. Even if the inside detection switch 2 and the outside detection switch 3 simultaneously detect the passing body B from time t 4 to time t 41 , the AND circuit 16 does not output the full open signal 17 . Therefore, while the object B passes through, the doors 1a and 1b remain at the predetermined opening position as in the case of one-way traffic.

イツチ5に検知されると閉駆動は停止する。 Next, to explain the two-way traffic shown in Fig. 6, this is a case where two objects pass through the automatic door from inside and outside at the same time. When the body D is detected by the outside detection switch 3 and the door opening detection switch 4 is not activated, the second signal 17 is output from the AND circuit 16 at the time t 6 when the body D is detected at the same time, and the second signal 17 is output from the drive circuit 10. starts the opening drive, and when the doors 1a, 1b reach the fully open position at time t 7 =t 6 +2To, the fully open position detection limit switch 7 detects this and the opening drive is stopped. The fully open state of the doors 1a and 1b is reached at time t8 when the passing object D passes through, and none of the detection switches among the inside detection switch 2, the outside detection switch 3, and the door opening detection switch 4 no longer detects the passing object. At this time t8 , the drive device 10 starts the closing drive until time t9 = t8 +2To.
When the doors 1a and 1b are fully closed and detected by the closed position detection limit switch 5, the closing drive is stopped.

る。 In two-way traffic, if there is a difference in the passing time of two vehicles facing each other and passing through the automatic door, the sixth
As shown in the figure, two-way traffic occurs, and the object E begins to pass through the automatic door from the inside to the outside at time t 10 , while the object E starts passing through the automatic door from the inside to the outside at time t 11 while the object E is being detected by the inside detection switch. Assuming that a passing object F begins to pass through the automatic door from the outside to the inside, when the passing object E is first detected by the inside detection switch 2, the first signal 13 is outputted through the OR circuit 12, and the drive device 10 begins to drive to open. Doors 1a and 1b begin to open. After time To, the doors 1a and 1b reach the predetermined opening position, and the drive device 10 is stopped by the detection signal from the predetermined opening position detection limit switch 6, but at time t11 , a passing object F is detected by the outside detection switch 3. Then, the signals from the inside and outside detection switches 2 and 3 are input to the AND circuit 16, and the door opening detection switch 4 is not activated and the self-holding circuit 1 is activated.
Since there is no signal at 4, a signal is input from the NOT circuit 15 to the AND circuit 16. Therefore, the second signal 17 is sent from the AND circuit 16 to the control circuit 11, and the drive device 10 starts the opening drive again, opening the doors 1a and 1.
b begins to open toward the fully open position at time t 12 = t 11 + To
When the fully open position is detected by the fully open position detection limit switch 7, the opening drive stops. The subsequent operation regarding the closing drive is exactly the same as in the case of two-way traffic.

して出力されることはない。 In addition, in the case of the above-mentioned two-way traffic, after the passing object C or E is detected by the door opening detection switch 4, the passing object D or F is detected by the door opening detection switch 4.
Since the time until it is detected is within the set time T1 of the set time circuit 19, the time counter circuit 1
A signal is output from 8 to the self-holding circuit 20,
At this time, since the doors 1a and 1b are already in the fully open position, the self-holding circuit 20 has been reset by the fully open position detection limit switch 7, so the second signal 21 is outputted from the self-holding circuit 20 to the control circuit 11. Never.

と判断して扉を全開するものである。 As in the above-mentioned case of two-way traffic, when two objects approaching the door from the inside and outside, that is, when the door opening detection switch 4 has not detected any objects, both the inside and outside detection switches 2 and 3 are activated. When the vehicle detects a passing body, it determines that the area near the door is crowded and opens the door fully.

チ5に検知されると前記閉駆動は停止する。 Next, to explain the continuous traffic shown in Fig. 6, first, at time t13 , a passing object G starts passing through the automatic door from the inside to the outside, and then at time t14 , a passing object H starts passing through the automatic door from the inside to the outside. If the object G starts passing at time t13 , the inside detection switch 2 is activated.
At the same time, the first signal is detected through OR circuit 12.
The signal 13 is output and the drive device 10 starts to drive to open, and after time To, when the doors 1a, 1b reach the predetermined opening position and are detected by the predetermined opening position detection limit switch 6, the opening drive stops and the doors 1a, 1b are opened. is maintained at a predetermined opening position. Between time t16 and time t17 , a passing object G is detected by the outside detection switch 3,
There is a state in which the passing body H is detected by the inside detection switch 2 at the same time, that is, a case where the inside and outside detection switches are in the detection state at the same time.
At t 15 , the passing object G activates the door opening detection switch 4.
The detection signal of the door opening detection switch 4 is detected by the self-holding circuit 14 from time t15 to the door opening detection switch 4.
Since it is held until time t 20 when a and 1b are fully closed, even if the inside and outside detection switches simultaneously detect a passing object from time t 16 to time t 17 , which is included in this time t 15 to time t 20 , The second signal 17 is not output from the AND circuit 16. However, the time counter circuit 18 starts counting from time t15 when the passing object G is detected by the door opening detection switch 4, and within the set time T1 of the set time circuit 19 which determines the reset time of the time counter circuit 18. time t 17 (time t 17 <
At t 15 + T 1 ), a passing object H activates the door opening detection switch 4.
Therefore, at this time t17 , the time counter 18 outputs an output to the self-holding circuit 20, and at the same time, the self-holding circuit 20 outputs the second signal 2.
1 is output to the control circuit 11. 2nd signal 2
The drive device 10 starts the opening drive by the control circuit 11 receiving 1, and opens the doors 1a and 1b at time t 18 = t 17 +To.
When it is fully opened, it is detected by the full open position detection limit switch 7 and the opening drive is stopped. At time t19 , when the passing object H has passed and all the detection signals from the inside/outside detection switch and the door opening detection switch disappear, the drive device 10 starts the closing drive, and when the doors 1a, 1b are fully closed at time t 20 =t 19 +2To and detected by the closed position detection limit switch 5, the closing drive is stopped.

通行体が通過する間、所定開度状態のままであ
る。 In contrast to the continuous traffic described above, in the case of continuous traffic shown in Fig. 6, the passing body detects the door opening detection switch 4.
The clock counter circuit 18 starts from the time t23 detected at
starts counting, and this time counter circuit 18
Since the passing object J is detected by the door opening detection switch 4 at time t 24 (time t 24 > t 23 +T 1 ) outside the set time T 1 of the set time circuit 19 that determines the reset time of
The time counter circuit 18 has already been reset and no output is sent to the self-holding circuit 20, so the second
Signal 21 does not appear. In other words, in the case of continuous traffic, even if two entrained objects pass through the automatic door in succession, the interval between detection by the door opening detection switch 4 is longer than the set time T1 , so the second signal is not output. It remains in the predetermined opening state while two passing objects pass through.

するものである。 When passersby pass through the door continuously, as in the above-mentioned continuous passage, the door opening detection switch 4 detects the interval at which passersby pass through the door, and this interval is within a predetermined set time T1. If so, it is determined that the area around the door is crowded and the door is fully opened, and if this interval is greater than the set time T 1 , it is determined that the area around the door is not crowded and the door is opened at a predetermined time smaller than fully opened. It opens to the opening degree.

とができるようになつている。 As described above, according to the automatic door control method of the present invention, when one object passes through the automatic door from the inside to the outside of the building, the opening of the two doors 1a and 1b of the automatic door is can be controlled to a predetermined opening smaller than a predetermined full opening, and this is exactly the same when a passing object passes through the automatic door from the outside to the inside of the building. Furthermore, even if objects pass through the automatic doors in the same direction consecutively, if the interval between passes is longer than a certain time, it is determined that the area near the doors is not crowded, and the doors 1a and 1b are closed.
is set to a predetermined opening position, and air conditioning loss can be prevented and energy savings can be achieved compared to conventional automatic doors that are fully opened in any case. Conversely, if multiple objects try to pass through the automatic door from opposite sides when the door is fully closed, or if multiple objects pass through the automatic door consecutively within a certain period of time, , it is possible to determine that the area near the automatic doors has become crowded and control the opening degrees of the doors 1a and 1b to be fully opened, thereby making it easier for pedestrians to pass through.
