[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door that is opened / closed by a motor, and more particularly to a control device for a security automatic door designed to prevent intrusion of outsiders.

[0002]

2. Description of the Related Art Conventionally, an automatic door of this type is known, for example, as shown in FIG. The automatic door includes both open doors 32 that are opened and closed by a motor (not shown) provided in the blind 31 at the top of the opening, and an indoor sensor provided above the both open doors 32 to detect a person. 33, an outdoor sensor 34 that is similarly provided above the outside of the open doors 32, and an intercom 35 provided on the outdoor side wall.
A timer 36 that repeats 24-hour clocking to turn on and off at a set time, a video camera device 37 provided on a side wall of the room to monitor a person near both doors 32, and a blind eye 3
The control unit 38 is provided in the control unit 1 and controls the motor based on signals from the sensors and the like (33, 34, 35, 36) to open and close both doors 32.

FIG. 5 is a connection diagram of the control unit 38 and sensors and the like. The indoor sensor 33, which is displayed as a switch that is turned on when a person is detected, includes a terminal 39 and a terminal 4 of the control unit 38.
0 connected directly, while the outdoor sensor 3 also displayed
Reference numeral 4 connects the terminals 39 and 40 via the push button switch 35a of the intercom 35 or the timer contact 36a of the timer 36 connected in series and the manual changeover switch 36b, and the terminals 39 and 40 are connected to each other. And the control unit 38
From the above, an opening command signal for opening both doors 32 is output to the motor. The timer contact 36a
For example, if the time to go to work and the time to go home are set in a residence, the function is turned on during the day when there is a manager, and turned off during the night when there is no manager. When the timer contact 36a is turned off, the control unit 38 outputs a recording command signal that causes the video camera device 37 to perform recording.

The control unit 38 controls opening and closing of the door as follows. First, assuming that the manual changeover switch 36b is on the normally closed side in the figure, during the daytime when the timer contact 36a is turned on, the outdoor sensor 34 is enabled in addition to the indoor sensor 33, so either sensor detects a person. Then, the control unit 38 outputs an open command signal to the motor to open the door so that both residents and visitors can freely enter and exit. Next, at night when the timer contact 36a is turned off, the outdoor sensor 34 becomes invalid, but the resident calls the resident by pressing the switch 35a of the intercom 35, and when the resident presses the switch in the room, Residents use intercom 35 key switch
Pressing (not shown) activates the outdoor sensors 34 respectively for a short time. Then, when the outdoor sensor 34 is turned on, the control unit 38 similarly opens the door, so that both the visitor and the resident can enter the room. On the other hand, even at night, the indoor sensor 33
Is effective, the door can be opened by the person detected by the indoor sensor, and the resident can go out of the room. When the manual changeover switch 36b is switched to the normally open side, the above-mentioned daytime operation can be performed regardless of the time measured by the timer. At night when the timer contact 36a is turned off, the video camera device 37 continues recording by a recording command signal from the control unit 38.

The control unit 38 is turned on (1) or off (0) by the above-mentioned indoor sensor 33, outdoor sensor 34, and timer contact 36a.
Whether there is an open command signal output from the motor to the motor (1, 0),
The night mode and the daytime mode are shown separately in FIG.

[0006]

However, in the above-described conventional automatic door control device, since the indoor sensor 33 is directly connected between both terminals 39 and 40 of the control unit 38, the timer contact 36a is turned off at night. Even if the outdoor sensor 34 is disabled by the above, as long as the indoor sensor 33 detects a person and is turned on, an open command signal is output even if the outdoor sensor 34 is turned on (see the bottom line of the night mode in FIG. 6). . In other words, if a thief or the like outside the room inserts thin paper or the like into the contact gap between the doors 32 and turns on the indoor sensor 33 (detection state), even if the outdoor sensor 34 detects the thief or the like, the control unit There is a problem that the opening command signal is output from 38 and the door is opened. At night when the timer contact 36a turns off,
Even when the outdoor sensors 33 and 34 do not detect a person,
Since the video camera device 37 always continues recording by the recording command signal of the control unit 38, there is a problem that it is uneconomical and there is not enough video tape.

Therefore, an object of the present invention is to devise the structure of a control unit for receiving on / off signals such as indoor and outdoor sensors, so that a thief or the like can easily enter and a video tape is insufficient. It is an object of the present invention to provide an automatic door control device capable of solving the above problem.

[0008]

In order to achieve the above object, a control device for an automatic door which is driven to open and close by a motor according to claim 1 is arranged so that at night, an object is simultaneously placed on the inside and the outside of the automatic door. Is detected, an opening command signal for opening the automatic door is not output to the motor.

The control device according to the first aspect does not output the opening command signal for opening the automatic door to the motor when an object is simultaneously detected on the indoor side and the outdoor side of the automatic door at night. Therefore, even if a thief or the like who is outdoors at night tries to open the door by inserting thin paper or the like through the gap of the automatic door to open the door, the outdoor sensor detects the thief or the like and the indoor sensor detects thin paper or the like. Therefore, the opening command signal is not output from the control device to the motor, and it is possible to reliably prevent the thief from entering.

A control device for an automatic door which is opened and closed by a motor according to a second aspect of the invention is provided inside the automatic door, and detects a person or an object near the automatic door and outputs an ON signal. A sensor and an outdoor sensor that is provided on the outside of the automatic door to detect a person or an object near the automatic door and output an ON signal, and performs timekeeping, and an ON signal is output during the daytime at night by setting the time. When a timer that outputs an OFF signal and an ON signal are input from the timer, when an ON signal is received from at least one of the indoor sensor or the outdoor sensor, or when an OFF signal is input from the timer, A control unit is provided which receives an ON signal from only the indoor sensor and outputs an opening command signal for opening the automatic door to the motor.

According to a second aspect of the present invention, in the control section of the control device, when at least one of the indoor sensor and the outdoor sensor detects a person or an object near the automatic door during the daytime when the ON signal is input from the timer, the motor is instructed to open. While outputting the signal to open the automatic door, at night when the OFF signal is input from the timer, when only the indoor sensor detects a person or an object in the vicinity of the automatic door, the automatic door is similarly opened. Therefore, in the daytime, even if a person stands near either or both the inside and outside of the automatic door, the control unit opens the automatic door via the motor based on the detection of the sensor, while at the night Has
Only when a person stands near the indoor side of the automatic door, the control unit similarly opens the automatic door based on the detection of the indoor sensor.
In other words, even if a thief stands near the outdoor side of the automatic door at night and activates the outdoor sensor, or if the thief inserts thin paper through the gap of the automatic door and simultaneously activates the indoor sensor, Does not output an open command signal to the motor, so it is possible to reliably prevent intrusion of thieves and the like.

According to a third aspect of the present invention, the control device monitors a person or an object near the automatic door and determines the remaining amount of the recording medium.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 is a connection diagram showing an example of a control device for an automatic door according to the present invention. This control device has substantially the same configuration as the control device described in FIG. 4 except that the control unit 1 is different, and the same. The same numbers are given to the members and the description thereof is omitted. The control device includes a control unit 1 and both doors 32 (see FIG. 4).
(Refer to FIG. 3), and a controller 2 for controlling the motor 3 by receiving each command signal as a contact output of the control unit 1.

On the input side of the control unit 1, an indoor sensor 33 that turns on by detecting a person or the like in the vicinity of both doors 32 is opened.
And an outdoor sensor 34 that turns on by detecting a person or the like near the outsides of both open doors 32, a push button switch 35a of an outdoor intercom, and clocks and turns on during the day and turns off at night according to the time setting. The timer 36 having the timer contact 36a and the manual switch 36b is connected. On the output side of the control unit 1, a video which outputs a warning signal when a video recording command signal is received to start shooting in the vicinity of the both doors 32 and the remaining amount of the video tape 4a as a recording medium falls below a predetermined value. A camera device 4, an alarm output contact 5 for outputting an alarm command signal for operating an alarm device such as a buzzer or a warning light, which is not shown, and terminals SS and G of the controller 2 at both ends.
Is connected to the motor 3 and the open command output contact 6 outputs the door open command signal to the motor 3 when turned on, and both ends are connected to the terminals ES and G of the controller 2, and outputs the door stop command signal to the motor 3 when turned on. The stop command output contact 7 is connected.

The control unit 1 receives each of the ON / OFF signals on the input side, and records, alarms, and records on the basis of the truth table shown in FIG.
The command signals for opening and closing are output from the output contacts. In this truth table, "0" means that the sensor or contact is off or the command signal is not output, and "1" means that the sensor or contact is on or the warning signal is output or the command signal is output. "*" Indicates that the input / output signal is irrelevant. The daytime mode refers to a period during which no warning is required between two times arbitrarily set by the 24-hour timer 36, and the nighttime mode refers to a period during which caution is required on both sides of the above two times.

The truth table of FIG. 2 differs from the conventional one shown in FIG. 6 in that the open command signal is not output when both the indoor and outdoor sensors are ON in the night mode, and the indoor sensor It is output only when it is on, and the video camera device 4
The video recording command signal to is not output when both the indoor and outdoor sensors are off in the night mode, and the alarm command signal is output when the outdoor sensor is on in the night mode. The stop command signal is a signal that is output in the night mode when both the indoor and outdoor sensors are on and stops the operation of the open door 32 by the motor 3. It is also possible to maintain safety by keeping the door open when exiting.

The control unit 1 for performing the operation of the truth table of FIG. 2 is realized by, for example, a logic circuit composed of AND, OR, and NOT gates shown in FIG. The input terminals on the left side of FIG. 3 show the corresponding sensor and switch numbers, and the output terminals on the right side show the corresponding terminals of the controller 2 and the symbols of the devices. Here, 36 b is a normally open contact of the manual changeover switch of the timer 36 (see FIG. 5), 4 b .
Is a warning signal output of the video camera device, and AL is an alarm device.

The automatic door control device having the above construction operates as follows. First, during the daytime when the timer contact 36a of the timer 36 is turned on, as shown in the lower half of FIG.
When at least one of the outdoor sensors 33, 34 detects a person or an object and is turned on, the control unit 1 outputs an open command signal from the contact 6 to the controller 2 and causes the motor 3 to open the both open doors 32. Therefore, during the daytime, even if a person or the like stands in one or both of the inside and outside of the both open doors 32, the both open doors 32 can be opened and freely accessed. Next, at night when the timer contact 36a is turned off, as shown in the upper half of FIG. 2, the control unit 1 sends an open command signal only when the indoor sensor 33 detects a person or the like and is turned on. Output from the contact 6 to the controller 2 to cause the motor 3 to open both doors 32. In other words, at night, a thief or the like stands up near the outside of the both open doors 32 to turn on the indoor sensor 34, or when the thief or the like inserts a thin paper or the like from the contact gap between the both open doors 32 and the indoor sensor 33 is turned on. Even if it is turned on, the control unit 1 does not output the opening command signal to the controller 2, so that the motor 3 does not open the both open doors 32, and the intrusion of a thief or the like is surely prevented.

Further, both the indoor and outdoor sensors 33 and 34 are turned on at night because normally only the indoor sensor 33 is turned on by detecting a person and the door is opened, and the person goes out of the room. Then, when the next person stands in the room and leaves immediately after the scheduled time. In this case, the control unit 1 outputs a stop command signal from the contact 7 to the controller 2 as shown in FIG.
Since the stopped state of the door is maintained, there is no risk that the exiting person will be caught by the closing door. Further, at night, as shown in the upper half of FIG. 2, when at least one of the indoor and outdoor sensors 33, 34 detects a person or the like and turns on, the control unit 1 sends a recording command signal to the video camera device 4. Output and start recording. Therefore, even if there is no person near both doors 32 even at night, the video camera device 4 does not record, which is economical because wasteful recording is eliminated and the video tape is used for a long time without replacement. be able to. At night, when the outdoor sensor 34 detects a person or the like and is turned on, or when the video camera device 4 outputs a warning signal because the remaining amount of the video tape is low, the control unit 1
An alarm command signal is output from the contact 5 to the alarm device. Therefore,
A security guard or the like can easily know the necessity of changing the video tape and the approach of a thief by the alarm issued by the alarm device.

[0021]

As is apparent from the above description, claim 1
Since the control device of the above does not output the opening command signal for opening the automatic door to the motor at the same time at night when an object is detected inside and outside the automatic door,
Even if an outdoor thief or the like tries to open the door at night by inserting thin paper etc. through the gap of the automatic door and operating the indoor sensor.
Since the outdoor sensor detects the thief and the like and the indoor sensor detects the thin paper and the like, the open command signal is not output to the motor, and the intrusion of the thief and the like can be reliably prevented.

According to a second aspect of the present invention, the control unit opens the motor when at least one of the indoor sensor and the outdoor sensor detects a person near the automatic door during the daytime when the ON signal is input from the timer. While the command signal is output, at night when the OFF signal is input from the timer, when only the indoor sensor detects a person in the vicinity of the automatic door, it also outputs an open command signal in the same manner. You can freely go in and out through the door, and at night you can surely prevent the intrusion of thieves and the like as above.

According to another aspect of the control device of the present invention, the control unit is at night when an off signal is input from the timer, and when a person or the like stands near either or both of the indoor side and the outdoor side of the automatic door. Since the recording command signal is output to the video camera device based on the detection of the sensor to start recording, wasteful recording is eliminated and it is economical, and the video tape can be used for a long time without replacement. In addition, the control unit
Is a recording medium at night when the off signal is input from the timer.
Is low and the video camera device issues a warning signal.
Room where force is applied or a person near the automatic door is detected
When the external sensor outputs an ON signal, the alarm command signal
