Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control system for automatic doors of windbreak rooms provided at entrances and exits of buildings, etc.

Traditionally, building entrances and exits have been used to prevent wind and rain from entering the building due to the entry and exit of pedestrians, and to prevent air conditioning and heating from entering and exiting the building.
Windbreak rooms are installed to block ventilation inside and outside the building, such as to prevent warm air from escaping outside. As shown in FIG. 1, this windbreak room includes a first door 1 that automatically opens and closes at one entrance of the windbreak room A, and a second door 2 that automatically opens and closes at the other entrance. 1st
Detection area 8 and detection area 4 in front and behind door l (traffic direction)
Detection area 5 is set up in front and behind the second door 2 (traffic direction).
In this configuration, when a passing object enters detection area 3 or detection area 4, it is detected and a door drive device (not shown) is activated based on the detection signal.
When the door opens and a passing object enters the detection area 5 or 6, it is detected, and based on the detection signal, a door drive device (not shown) is operated to open the second door.

However, the door of such a conventional windbreak room A detects, for example, when a passing object enters the detection area 3 and opens the first door 1, and then opens the first door 1 until the passing object passes and leaves the detection area 4. The first door 1 is kept open. However, as mentioned above (7), the purpose of a windbreak room is to connect ventilation between the inside and outside of a building, so the door must be closed as soon as possible after a person passes through. There was a problem with the door not closing immediately after a passerby passed through it.In addition, in order to solve the above problem, it is necessary to prevent the detection of objects passing through the door and moving away from the door. Often, in order to achieve this, it is sufficient to install a detection circuit capable of detecting directionality, which has been proposed in the past, but in this case, as shown by the dotted line in FIG. A detection work IJA 8 is set adjacent to the detection area 4, and when a passing object enters from the detection area 4 toward the detection area 7, the door of the first door 1 is set adjacent to the detection area 4. An open signal is not emitted to the drive device, and when a passing object enters from the detection area 7 toward the detection area 4, an open signal is emitted to the door drive device of the first door l, and an open signal is made to be emitted to the door drive device of the first door l. Similarly, when a passing object enters the detection area 8 from the detection area 6, the opening signal is not issued to the door drive device of the second door 2, and the door drive device from the detection area 8 moves to the detection area 6. It is only necessary to configure a control circuit with a direction selection function so that an opening signal is issued to the door driving device of the second door 2 when a passing object approaches the door.
With such a configuration, if a passing object passes through the 1s or 2nd door and enters the windbreak room, the door can be closed quickly, but the reason for the detection switch in each detection area is that the conventional two A problem arises in which the number is doubled from 4 to 4.

Therefore, in view of the problems mentioned above, the present invention aims to close the door as soon as possible after a passerby has passed, without increasing the number of detection switches in the windshield room. A specific solution is to form a first detection area and a second detection area between one door and the other door of the windbreak room and in the direction of traffic, and to connect the first detection area to the second detection area. When a passing object moves in the direction of the area, the one door in the direction of movement is opened, and when the object moves from the second detection area in the direction of the first detection area, the other door in the direction of movement is opened. This is an automatic door control system for windbreak rooms that controls the opening of the door.

The present invention will be described below based on an embodiment shown in the drawings. In Fig. 2, a detection area 10 is set near the outside of the windbreak room A of the first door l provided at one entrance of the windbreak room A, and a detection area 10 is set at the outside of the first door l provided at the other entrance of the windbreak room A. A detection area 11 is set near the outside of the windbreak room A of the second door 2.

A detection area 12 and a detection area 13 are set near the center of the interior of the windbreak room between the first door 1 and the second door 2 in the direction of traffic (left and right in the figure). It is arranged on the door l side, and the detection area 13 is arranged on the second door 2 side. 1

This is a self-maintaining configuration. Furthermore, the output terminal of the second AND circuit AN2 is connected to the first OR circuit ORI as the output terminal of the direction selection circuit M. The direction selection circuit Nrx is basically the same as the direction selection circuit M described above, so to briefly explain it, a fourth detection switch S4 and a third detection switch S3 are connected to the input terminal of the third AND circuit AN3 from the timer T7. connected through the second NOT circuit NO2, and the fourth OR circuit 4.
The output terminal of the third AND circuit AN3 is connected to the input terminal of the third AND circuit AN3 via a timer T8, and the output terminal of the fourth OR circuit OR4 and the third detection switch S3 are connected to the input terminal of the fourth AND circuit AN4 via the timer T8. T7, and the output terminal of the fourth AND circuit AN4 is connected to the fourth OR circuit O.
The output terminal of the fourth AND circuit AN4 is connected to the input terminal of the second OR circuit OR2 as the output terminal of the direction selection circuit N. The output end of the first OR circuit ORI is connected to a first control section 16 that outputs a door open or close signal based on this output, and the output end of this first control section 16 is connected to this open or close signal. It is connected to a first door driving device 17 that opens or closes the first door l based on the output of the first door l. Said second

Next, the operation of the embodiment constructed as described above will be described. First, before explaining the overall operation, the operation of the direction selection circuit M will be explained with reference to the time chart of FIG. 4. When the fourth detection switch S4 is activated after the third detection switch S3 is activated, as shown in the time chart of FIG.
This signal H is input to the first AND circuit ANI, and on the other hand, the fourth detection switch S4 outputs the signal H with a slight delay from the signal H of the third detection switch 83, and this signal H is input to the delay timer T1. and is held for a set time tI.
It is inverted by the NOT circuit NOI and becomes the first AND circuit ANI.
is input. Then, as shown in the figure, this first AND circuit A
A signal H is output from NI, and this output signal H is input to the second AND circuit AN2 via the third OR circuit ORB while being held for a set time of 16 by the delay timer T2, and is also input to the second AND circuit AN2 via the third OR circuit ORB. The signal H from the second AND circuit A is held for a set time t5 by the delay timer T5.
It is input to N2. At this time, the output of the second AND circuit AN2 is input to the input terminal of the third OR circuit ORB and is self-maintained. Therefore, when the output signal H from the second AND circuit AN2 is output at one end, the signal H output from the fourth detection switch S4 via the delay timer T5 disappears.

When the third detection switch S3 is activated, the
), the fourth detection switch S
4 outputs a signal H, which is held for a set time t5 by a delay timer T5, inverted by the first NOT circuit NOI, and inputted to the first AND circuit AN1, while being input to the first AND circuit AN1 by the fourth detection switch s4. The third detection switch s3 outputs the signal H with a slight delay from the signal H, and the first AND circuit ANI outputs the signal H, and the output signal H is held for a set time of 16 by the delay timer T2. Meanwhile, it is input to the second AND circuit AN2 via the third OR circuit oR3.

However, this second AND circuit AN2 is connected to the first AND circuit AN2.
The signal H from I to the delay timer T6 and the third OR circuit o
When input via R3, the second AND circuit AN2
Since the signal H from the fourth detection switch s4 has passed the set time t5 of the delay timer T5 and no signal is input to the other manual terminal, no signal is output from the second AND circuit AN2. In this way, the direction selection circuit M outputs the output signal H when the fourth detection switch s4 is activated after the third detection switch S3 is activated, and the direction selection circuit M outputs the output signal H when the fourth detection switch s4 is activated after the third detection switch S3 is activated.
After the third detection switch s3 is activated, no output signal is output when the third detection switch s3 is activated. Also, the direction selection circuit N is basically the same as the direction selection circuit M, and its output signal is simply reversed, so the explanation will be omitted, but the direction selection circuit M,
When the third detection switch S3 is activated after the fourth detection switch S4 is activated, the output signal i] is output, and when the fourth detection switch S4 is activated after the third detection switch S3 is activated, the output signal i is output. No. g is not output.

Therefore, in Fig. 2, when a passing object comes from the X direction in the figure, tlt + (when the living body enters the detection area IO, the
Detection switch S1 is activated, and its signal H is sent to delay timer T.
A signal H is input to the first OR circuit ORI while being held for a set time at I, and a signal H is output to the first control section 16, which outputs an open signal. Based on this opening signal, the first door driving device 17 is driven and the first door is opened. When a passing object passes and the set time of the delay timer TI has passed, a signal is output from the delay timer 'I''l. Since it is not done, i
A close signal is output from the t control unit 16 to the first door driving device 1i17, and the first door 1 starts to close. At this time, the traffic body is the 1st nl
When there is a VC nearby, the safety switch 14 is activated, and the signal H is input to the first OR circuit ORI while being held for a set time by the delay timer T2, and the signal H is output to the first control unit 16. An open signal is output from the control unit 16 to drive the first door driving device 17 to maintain the first door 1 in an open state to ensure safety. At that point, the object passes through the 1st fil and passes through the 4th fil.
When the detection switch S4 advances from the detection area 12 to the detection area 13 of the third detection switch S3 and reaches position 1, the eighth detection switch S is activated after the fourth detection switch S4 is activated.
3 is activated, and as described above, no signal is output from the second AND circuit AN2 of the direction selection circuit M. Therefore, the first control unit 16 outputs a close signal to the first door driving device 17, and the first door is closed. It does not cause l to be opened. - A signal H is output from the fourth AND circuit AN4 of the force direction selection circuit N,
The signal is input to the second control section 18 via the second OR circuit OR2. Therefore, the second control unit 18 outputs an open signal to the second door drive device 19, and the second door drive device 19 is driven to open the second door 2 in the traveling direction of the object (left direction in the figure). do. At this time, the door is opened as much as possible when the 1η striking body advances from the position Kl to the second door 2, so that it can pass through smoothly. Thereafter, when the object passes through the second door 2 and passes the detection area 11, the second door 2 begins to close. Then the second

is input to the second control unit 18 via the second OR circuit OR2 while being held for a set time by the delay timer T31C, and the second control unit 18 outputs an open signal to the second door drive device 19, and this open signal Based on this, the second door driving device 19 is driven to open the second door 2. Passage object passes and delay timer T3
After the set time has passed, the delay timer T3 does not output a signal, so a closing signal is output from the second control section 18 to the second door driving device 19, and the second door 2 starts to close. At this time, when a passing object is near the second door 2, the safety switch 15 is activated and the signal H'2 is activated, as in the case of the first door described above.
5, the signal is input to the second control unit 18 via the second OR circuit ORI while being held for a set time by the delay timer T4, and the second control unit 18 outputs an open signal to drive the second door drive device 19. The second door 2 is held open to ensure safety. When the object passes through the second door 2 and advances from the detection area 12 of the third detection switch S3 to the detection area 12 of the fourth detection switch S4 and reaches position 2, the third detection switch S3
Since the fourth detection switch S4 is activated after the
As mentioned above, the second AND circuit AN2 of the direction selection circuit M
A signal H is output from the circuit 1 and is input to the first control section 16 via the first OR circuit ORI. Therefore, the first control unit 1

The door driving device 17 is driven to open the first door in the traveling direction of the object (to the right in the figure). At this time, the passing object is in position 2
Open the door as much as possible before proceeding to the first Jil so that you can pass through smoothly. - Since no signal is output from the fourth AND circuit AN4 of the force direction selection circuit N, the closing signal is sent from the second control unit 18 to the second door driving device 19.
The second n2 is not outputted to open the second n2. After that, a passing object passes through the opened first door l and the detection area 10
After passing , the first door l begins to close. For passing objects that have passed through various fields and entered the windbreak room A,
The direction of movement of the object in the detection area 18 of the third detection switch S3 and the detection area 12 of the fourth detection switch S4 is detected, and the door in the direction of movement is opened early to allow the object to pass smoothly. The door is controlled so that it closes as quickly as possible without giving an open signal to the door it passes through.

FIG. 5 shows another embodiment of the present invention, in which a photoelectric switch 20.21 is used as the third detection switch S3 and the fourth detection switch S4 in FIG.
A photoelectric switch 20, 21 is provided between the door 1 and the second door 2 in a direction perpendicular to the direction of traffic (left-right direction in the figure), and these photoelectric switches 20 and 21 form detection areas 23 and 22, respectively. . The actual M example shown in FIG. 5 has basically the same function as the above-described embodiment shown in FIG. 2, so a description thereof will be omitted. Note that various detection switches other than the photoelectric switch, such as a T-wave switch, a hot wire switch, and a mud switch, may be used.

Furthermore, FIG. 6 shows another embodiment of the present invention. In FIG. 2, the detection areas 12 and 13 are simply arranged side by side in the traffic direction (left and right directions in the figure), whereas in FIG. Detection areas 24 and 25 are arranged side by side with some overlap in the left/right direction). The embodiment shown in FIG. 6 has basically the same function as the embodiment shown in FIG. The door can be opened early so that the coming passerby can pass through the door in the direction of travel more smoothly without having to wait. That is, when a passing object that has passed through the first door 1 and entered the windbreak room A advances from the detection area 24 to the detection area 25, the second door 2 is opened at the position L1 in the figure. The second door 2 can be opened while the passing body advances from the position LH to the second door 2, and the object can smoothly pass through the second door 2. Furthermore, when a passing object that has entered the windbreak room A through the second door 2 advances from the detection area 25 to the detection area 24, the first door 1 is opened at the position L2 in the figure. Figure 7 shows the entrance and exit of the windbreak room, which can be controlled and the first door 1 can be opened while the passing object moves from the position 2 to the first door 1, allowing it to pass through the first door 1 smoothly. The present invention is applied to a case where there are three entrances, for example, one entrance leads into the building and the other two entrances lead to the outside. That is, the 1st fil and the 1'th door 1
' is connected to the outside, the second door 2 is connected to the internal pressure of the building, and the first
nl and 1st door 1' and 2nd JS2, the direction of the traffic (direction B in the figure) is placed inside the windbreak room A between the 1st door l and 2332. ) detection area 3
0 and 81t- are installed side by side, and detection areas 32 and 31' are installed side by side in the windbreak room A between No. 1'B1' and No. 2n2 in the direction of traffic (direction C in the figure). , its operation is basically the same as the embodiment shown in FIG. The first door 1 is controlled to be opened when the object advances from the detection area 82 to the detection area 31.
The second door 2 is opened when the vehicle advances from the detection area 31 to the detection area 82, and the first 'door 1' is opened when the vehicle advances from the detection area 31 to the detection area 82. In this manner, the control circuit described in FIG. 2 can be basically applied to control the doors at the entrances and exits of various windbreak rooms.

In addition, in each of the embodiments shown in FIGS. 2, 5, and 6, there is a detection area 10 outside the windbreak room A of 1.2 in each field.
．． For example, as shown in Figure 6, in addition to detection area 10.11, detection area 26.27 is installed in parallel outside the windbreak room A of each area 1.2. death,
If the direction of the passing object is detected, the door can be closed as quickly as possible after the passing object passes through the door from inside the windbreak room A to the outside, which will further improve the situation. Alternatively, a photoelectric switch or the like may be used as each detection switch installed outside the windbreak room in each field. Furthermore, as shown in Figure 6,
In order to clarify the passing area of the passing object in the windshield room A, the passing direction of the passing object can be reliably detected by providing passage walls 28 and 29 along the passing direction.

As is clear from the above, according to the present invention, two detection areas are provided in the direction of passage of objects between the doors in the windbreak room.
The direction of movement of objects passing through is detected by the activation order of these detection areas, and the door in the direction of movement is controlled to open, so there is no need to increase the number of detection switches in the windshield room. If a passing object passes through the door and enters the windbreak room, the door that it passed through can be closed quickly, which improves the blocking effect of blocking ventilation inside and outside the building.
Q has the advantage of being able to fully open the door in the direction of movement for passing objects entering the shelter and windbreak room, allowing the passing objects to move smoothly into the windbreak room. be.
