CONSTITUTION:A sensor 2 for sensing a person for coming into a room when he comes close to the front of doors 1a and 1b is provided to an automatic door equipment which is operated for opening the doors 1a and 1b when a collating device 4 installed to a position near the doors 1a and 1b on a gateway identifies the person coming in with an authorized one. The sensor 2 is so constructed that it functions as a sensor, when the collating device 4 makes identification of the person authorized for entrance, for a period of time corresponding to a distance between the installation position of the collating device 4 and the front of the doors 1a and 1b, and the doors 1a and 1b are driven only when the sensor 2 senses the coming-in person during the period in which the sensor 2 functions. When the doors 1a and 1b come to their positions of complete closing within the operating time of the sensor 2, the remaining operating time is reset for the sensor 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling an automatic door for restricting entry into a building or a room by means of a collating device such as a numeric keypad or a card reader.

[0002]

2. Description of the Related Art Conventionally, as such an automatic door, for example, there is one shown in FIG. 8 (JP-A-60-3376).
In this case, a card reader 52 that determines whether or not a key card is valid is installed on the outer surface of the slide type automatic door 51 installed at the entrance 50 of the hotel. When the guest inserts the key card into the card reader 52 and it is determined that the key card is valid, the door 5
1, 51 are opened to allow guests to enter the hotel.

On the outer surfaces of the doors 51, 51, electrostatic switches 53, 53 that can be switched with the card reader 52 are installed, so that a person who wants to enter the hotel in the daytime
By touching the electrostatic switches 53, 53, the doors 51, 51
You can freely open and close by opening and closing.

[0004]

In the above automatic door, when the card reader 52 determines that the key card possessed by the guest is valid, the doors 51, 51 are immediately opened and closed.
When the card reader 52 is installed away from the vicinity of the automatic door, the door 5 is opened before the guest reaches the doors 51, 51.
There is a possibility that the opening and closing operations of 1 and 51 are completed, the doors 51 and 51 are fully closed again, and the guest cannot enter.
Therefore, the installation place of the card reader 52 is the doors 51, 51.
There is a restriction that it must be close to. However, for example, automatic doors installed at the entrances of condominiums, hotels, etc. are often made of transparent tempered glass in order to improve the scenery of the building.
As shown in Fig. 5, the outer surfaces of the doors 51, 51 and the wall body 5 of the door pocket part
It is practically impossible to attach it directly to 4, 54 and enforce it. Therefore, there is a problem that it cannot be applied to such a mounting site.

[0005]

The technical means of the present invention for solving this problem is to install a collating device around the door of the entrance / exit for determining whether or not the person is an entry permitter. In the automatic door that the collating device collates the occupants and drives the door when it is determined that the person is a room-entry permitter, a detection sensor is provided in front of the door to detect that the occupant is approaching. When the collation device determines that the collation device is a person who is allowed to enter the room, the detection sensor is operated only for a time corresponding to the distance from the installation place of the collation device to the front surface of the door, and the detection sensor is activated. The door is driven when a person entering the room is detected within the time.

[0006]

According to this means, after the collation device determines that the person is a person who is permitted to enter the room, the detection sensor operates for a time corresponding to the distance from the installation place of the collation device to the front surface of the door,
Within this time, the detection sensor detects a person approaching the front of the door and drives the door for the first time, so by adjusting the operating time of the detection sensor, the distance from the front of the door to the matching device can be set arbitrarily. .

[0007]

[Embodiment] An embodiment in which the present invention is applied to an automatic door installed at the entrance of a condominium will be described below.
FIG. 1 shows a schematic configuration diagram of an automatic door including peripheral devices. A slide type automatic door 1 suspends and supports the doors 1a and 1b on an upper rail in an engine cover 6, and a door engine 7 opens an entrance. It is configured to open and close. Inside the engine cover 6, there are provided a reed switch 8 for detecting the fully closed position of the doors 1a, 1b and an electromagnetic lock 9 for locking the doors 1a, 1b at the fully closed position. When the lock signal is received, the doors 1a and 1b are unlocked, and when the doors 1a and 1b are opened and returned to the fully closed position, the doors are automatically locked.

On the front of the outdoor doors 1a and 1b, a detection sensor 2 for detecting a person who is about to enter the condominium.
However, detection sensors 3 for detecting a person leaving the condominium are provided on the front surfaces of the doors 1a and 1b on the indoor side. The detection sensor 2 is connected to the controller 5 installed in the manager's room in the apartment, and the detection sensor 3 is connected to the control unit 7a (see FIG. 2) of the automatic door 1. Further, safety sensors 10 and 10 are installed at both ends of the outdoor doors 1a and 1b in the opening / closing direction to detect a person who is outside the detection areas of the detection sensors 2 and 3 and stops on the opening / closing path of the doors 1a and 1b. Yes, like the detection sensor 2, it is connected to the controller 5.

The controller 5 is connected to a collation device 4 such as a ten-key 15 for determining whether or not the user is a registrant, a card reader 16 and the like. The collation device 4 is separated from the outdoor entrance. It is installed in the position. An intercom slave 14 that can communicate with the intercom master 13 in the manager's room is installed near the matching device 4. When there is a visitor, the intercom master 13 sends a remote signal to the controller 5 to enter the room. It is possible. Further, the controller 5 is connected to a door opening alarm buzzer 11 that warns of abnormal opening of the doors 1a and 1b, and a schedule timer 12 that switches between a time zone for restricting entry and a time zone for freely entering and exiting.

FIG. 2 shows a control block diagram of the automatic door of FIG. 1, and the parts corresponding to those of FIG. 1 are designated by the same reference numerals.
The controller 5 includes an unlock / door openability determination unit 5a, an unlock /
It includes a door opening signal output unit 5b and a door opening condition setting unit 5c. The unlock / open door availability determination unit 5a includes a collation device 4 and a safety sensor 1.
0, the detection sensor 2, the schedule timer 12, the intercom master unit 13, the reed switch 8, and the electromagnetic lock 9 are received, and it is determined whether or not the doors 1a and 1b can be opened / closed by these signals to unlock / unlock. A door open signal and an unlock signal are output from the door signal output unit 5b. In addition, the unlocking / opening possibility determination unit 5a includes a sensor valid timer 5c1 and an alarm timer 5c.
2 is connected to the door opening condition setting unit 5c having 2 to enable the detection signal of the detection sensor 2 only for the timer time of the sensor valid timer 5c1 and the doors 1a, 1b even if the timer time of the alarm timer 5c2 has elapsed. If the door does not return to the fully closed position, the door open alarm buzzer 11 is activated.
The sensor effective timer 5c1 is set to a time corresponding to the distance from the front surfaces of the doors 1a and 1b to the installation location of the matching device 4, for example, a time required for a general person to walk, and an alarm is issued. The timer 5c2 is set to be approximately the same as the time required for the doors 1a and 1b to open and close.

The unlocking / opening door possibility determining unit 5a is provided with a collating device 4
Upon receiving the entry permission signal from, the sensor valid timer 5c1 of the door opening condition setting unit 5c is activated, and the detection signal of the outdoor detection sensor 2 is validated for this timer time. If there is no ON signal of the detection sensor 2 (indicating that there is a person who wants to enter the room within the detection area of the detection sensor 2) within the timer time of the sensor valid timer 5c1, it is determined that there is no intention to enter the room. , The detection signal of the detection sensor 2 is invalidated. When the ON signal of the detection sensor 2 is received, the unlocking / opening signal output unit 5b outputs an unlocking / opening signal to the control unit 7a of the automatic door 1. As a result, the control unit 7a of the automatic door 1 sends an unlocking signal to the electromagnetic lock 9 and then sends a door opening signal to the door engine 7 to open the doors 1a and 1b.

When the doors 1a and 1b start to open, the reed switch 8 and the electromagnetic lock 9 send an OFF signal to the unlocking / opening possibility determining section 5a of the controller 5, and the unlocking / opening possibility determining section 5 is detected.
In response to the OFF signal from the reed switch 8, a activates the alarm timer 5c2 of the door opening condition setting unit 5c and validates the detection signals of the safety sensors 10 and 10. Within the timer time of the alarm timer 5c2, the doors 1a, 1
If b is returned to the fully closed position and there is no ON signal from the reed switch 8, it is determined that the doors 1a and 1b remain open, and the door open alarm buzzer 11 is activated. Also,
If the occupants are blocking the safety sensors 10 and 10,
Since the unlocking / opening signal output unit 5b continues to output the unlocking / opening signal, the doors 1a and 1b are held in the open state to prevent the occupant from being caught between the doors 1a and 1b.

When the doors 1a, 1b return to the fully closed position and receive the ON signal from the reed switch 8, the safety sensor 1
The detection signals of 0 and 10 are invalidated, and the operation of the door opening alarm buzzer 11 is stopped. Therefore, the safety sensors 10 and 10 are invalid unless a room entry permission signal is received from the collation device 4, and even if an outsider interrupts the safety sensors 10 and 10, the doors 1a and 1b are opened. There is no.

When there is a switching signal from the schedule timer 12, the detection sensor 2 is always enabled, and when the detection sensor 2 detects an occupant, the door 1 is operated as described above.
Drive a and 1b. Further, when there is a person leaving the condominium, the detection sensor 3 on the indoor side detects the person leaving and the control unit 7a of the automatic door 1 is independent of the controller 5.
After releasing the unlocking signal to unlock the electromagnetic lock 9, a door opening signal is sent to the door engine 7 to drive the doors 1a and 1b to exit the condominium.

Next, the operation of one embodiment of the present invention will be described with reference to the flow charts shown in FIGS. 3 to 5 and the time charts shown in FIGS. 6 and 7. First, as shown in FIG. 3, it is determined whether or not the indoor detection sensor 3 is on (step S1). If the detection sensor 3 is off, then the intercom base unit 13 in the manager's room is remoted. It is determined whether or not there is a signal (step S2). If there is no remote signal from the intercom base unit 13, the collation device 4
It is determined whether or not there is an input operation to (step S
3) If there is no input operation, the above operation is repeated again.

In step S3, when an input operation is performed on the collation device 4, the input data is collated with the data registered in advance, and whether or not the person who is about to enter the condominium is a registrant. Is determined (step S
4). If the user is not a registered person, the process returns to step S1 and the above operation is repeated. If it is determined that the user is a registrant, the sensor valid timer 5c1 is activated (step S
5). In step S2, if there is a remote signal from the intercom master unit 13 in the manager's room, the sensor valid timer 5c1 is used as in the case of determining that the user is a registrant.
Operate.

As a result, the detection signal of the detection sensor 2 becomes the timer time T1 (for example, as shown in the time chart of FIG. 6).
Only 60 seconds) is valid. Then, it is determined whether or not the sensor valid timer 5c1 is up (step S6), and it is determined whether or not the outdoor detection sensor 2 is turned on (step S7). When the detection sensor 2 is determined to be off in step S7, it is determined again in step S6 whether or not the sensor valid timer 5c1 has timed out, and the above operation is repeated until the timer time T1 times up. .. When the occupant approaches the front of the doors 1a and 1b and the detection sensor 2 is turned on during the timer time T1 of FIG. 6, the detection sensor 2 is detected in step S7.
Is determined to be ON, an unlocking / opening signal is output (step S8), and the doors 1a and 1b are opened (step S8).
9) Allow entry into the condominium.

If the detection sensor 2 does not detect an occupant during the timer time T1 of the sensor valid timer 5c1, it is determined in step S7 that the detection sensor 2 is off, and in step S6. When the timer time T1 is up, it is determined that there is no intention to enter the room, and the operations of steps S1 to S5 are repeated again.

When the doors 1a and 1b start to open, the reed switch 8 for detecting the fully closed state of the door is turned off as shown in the time chart of FIG. 6, and accordingly the safety sensor 1
Enables detection signals 0, 10 and alarm timer 5
c2 is operated for the timer time T2 (step S1
0). Subsequently, as shown in FIG. 4, it is determined whether or not the sensor valid timer 5c1 has timed out (step S11). If not, it is determined whether or not the alarm timer 5c2 has timed up. (Step S12), if the time is not up, the detection sensor 2
It is determined whether or not is on (step S13). That is, it is determined whether or not an occupant has stopped in front of the doors 1a and 1b. If not stopped, safety sensor 1
It is determined whether 0 and 10 are on (step S1
4). That is, it is determined whether or not there is a person standing in the opening / closing path of the doors 1a and 1b. If the doors 1a and 1b have not returned to the open / close path, it is determined whether or not the doors 1a and 1b have returned to the fully closed position and the reed switch 8 is on (step S
15) If there is an ON signal from the reed switch 8, it is judged that the person has entered the apartment, and the sensor effective timer 5
The operation of c1 is stopped (step S16). Therefore, as shown by the broken line in FIG. 6, the remaining timer time T1 of the sensor valid timer 5c1 is reset, the detection signal of the detection sensor 2 is invalidated, and entry of anyone other than the registered person is blocked.

If the occupant remains at the entrance, it is determined in step S13 that the detection sensor 2 is on, so the unlocking / opening signal continues to be output (step S19), and the door is opened. A door open signal is sent to the engine 7 to hold the doors 1a and 1b in the open state (step S2).
0). Then, again in step S11, it is determined whether or not the sensor valid timer 5c1 is up, and the above operation is repeated until the time is up. During this operation, the timer time T2 of the alarm timer 5c2 is set to the time required to open and close the doors 1a and 1b, and therefore, as shown in the time chart of FIG. 7, it is longer than the timer time T1 of the sensor valid timer 5c1. It is short, and the time is up before the sensor effective timer 5c1 in step S12. For this reason, the door opening alarm buzzer 11 is sounded (step S18) to notify the occupant that the doors 1a and 1b are in the open state, and promptly enter the room.

If the person entering the room is out of the detection area of the detection sensor 2 and is standing still in the opening / closing path of the doors 1a, 1b, it is determined in step S14 that the safety sensors 10, 10 are on, and the sensor is effective. Until the timer 5c1 times out, the above operation is repeated until the doors 1a, 1b
Is kept open to prevent the person entering the room from being caught between the doors 1a and 1b. At this time, in step S12, when the timer time T2 of the alarm timer 5c2 has expired, the door open alarm buzzer 11 is sounded in the same manner as described above, and it is notified to the occupants that the doors 1a and 1b remain open. Notify me and encourage early entry.

When a person who has stopped in the detection area of the detection sensor 2 or a person who has stopped in the opening / closing path of the doors 1a and 1b enters the apartment, the detection sensor 2 and the safety sensor 10 are turned off. So
In step S15, it is determined whether the doors 1a and 1b have returned to the fully closed positions and the reed switch 8 is on. If it is on, the valid timer 5c1 is determined in step S16.
Then, as shown in the time chart of FIG. 7, the operation of the door opening alarm buzzer 11 is stopped (step S
17). In this state, since the safety sensors 10 and 10 are disabled, even if an outsider is in the detection area of the safety sensors 10 and 10, it is possible to prevent an outsider from entering.

If the doors 1a, 1b do not return to the fully closed position due to the obstacle, it is continuously determined that the reed switch 8 is off in step S15. Therefore, unless the obstacle is removed, the process proceeds to step S18. The door open alarm buzzer 11 continues to sound to notify the abnormal opening of the doors 1a and 1b.

When the person entering the room is detected by the detection sensor 2 just before the timer time T1 of the sensor effective timer 5c1 is up (YES in step S7), steps S8, S9 and S10 are executed to open the door 1a. 1b
Is opened, the alarm timer 5c1 is started, and the safety sensors 10 and 10 are validated. However, since the timer time T1 of the sensor valid timer 5c1 is immediately expired, step S11
At, it is determined that the sensor valid timer 5c1 has timed up. At this time, if the time required for the doors 1a and 1b to open and close has not yet elapsed, the alarm timer 5c2 has not expired (the determination in step S21 is NO), and the person occupying the door 1a, If it remains stopped before 1b, the safety sensors 10, 10
Is still off (No in step S22), the detection signal of the detection sensor 2 becomes invalid during the opening / closing operation of the doors 1a and 1b, and the occupant is not detected by the detection sensor 2 and the door is not detected. 1a and 1b return to the fully closed position,
When the reed switch 8 detects this return (Yes in step S23), it becomes impossible to enter the room.

Before the doors 1a and 1b are returned to the fully closed position, the occupants of the room shut off the safety sensors 10 and 10 (step S22).
If YES, the unlocking / opening signal is continuously output (step S24), the opening signal is sent to the door engine 7, and the doors 1a and 1b are maintained in the open state (step S25). This operation is repeated while the occupant shuts off the safety sensors 10 and 10. However, when the time required to open and close the doors 1a and 1b has passed, the timer time T2 of the alarm timer 5c2 is increased (determination in step S21 is made. (Yes), the opening alarm buzzer 11 is sounded (step S26) to inform that the door is in the open state, and prompt the occupants to enter the room early.

Then, the occupants enter the apartment,
When the reed switch 8 detects that the doors 1a and 1b have reached the fully closed position, the doors 1a and 1b are detected in step S23.
Is determined to be closed, and the operation of the door opening alarm buzzer 11 is stopped in step S17. In this state, since the safety sensor 10 is disabled, the safety sensor 10, 10 is not blocked by an outsider, and the outsider's intrusion can be prevented in the same manner as above. If the doors 1a and 1b are open due to an obstacle, step S23 is performed.
Since it is determined that the reed switch 8 is off in step S26, the alarm buzzer 11 is sounded in step S26, and the door 1
Notify abnormal release of a and 1b.

When there is a person who leaves the condominium, the indoor detection sensor 3 is detected in step S1 of FIG.
Is determined to be on, and as shown in FIG. 5, an unlocking / opening signal is immediately output (step S27). As a result, the locked state of the electromagnetic lock 9 is released, and the door engine 7 opens and closes the doors 1a and 1b (step S28).
The alarm timer 5c2 is activated (step S29). As long as the detection sensor 3 and the safety sensors 10 and 10 are on, the doors 1a and 1b are kept open and the alarm timer 5
After the timer time T2 of c2 has expired, sounding the door open alarm buzzer 11 to warn the leaving person to leave early is processed in steps S30 to S36 similar to steps S12 to S18.

[0028]

As described above, according to the present invention, the detection sensor on the front surface of the door is determined according to the distance from the installation place of the verification device to the front surface of the door after it is determined that the verification device is the person who has permission to enter the room. The detector is operated for a certain period of time, and the door is driven when a person approaching the front of the door is detected within the operating time of this detection sensor. Can be installed away from the automatic door, and by freely adjusting the operating time of this detection sensor, the installation location of the matching device can be freely selected.

Further, once the operation effective time of the detection sensor is
After the door opens and reaches the fully closed position, it is reset, so it can be detected even after the collating device reaches the automatic door quickly due to the difference in the walking speed of the person and the door opens and closes. Even when the sensor operation valid period is left over, the remaining time is reset, so that it is possible to prevent anyone other than the registered person from entering the room.
