JP 2008-138440 A

  However, since the conventional automatic door opening and closing device has to keep the human body detecting means in an operating state, it can not only reduce power consumption, that is, running cost, but the human body detecting means is always in an energized state. Since it is held, there is a problem that its life is shortened.

  Moreover, the conventional automatic door opening and closing device described above is effective for one person to use in an open space such as a front door, but opens and closes the door facing the corridor in a building that is always used by a plurality of persons. It is not easy to use in order to maintain a certain level of security by identifying people who can enter and exit within a narrow range, such as when there are multiple doors close to the corridor.

  The present invention eliminates the above-mentioned problems in the prior art, such as an action in which a person moves a part of the body closer to a human body detector, and allows a facility user to open the door in a hands-free state. An object of the present invention is to provide an automatic door opening and closing device that can reduce the power consumption of the sensor, reduce the running cost, and extend the life of the human sensor.

  In order to solve the above problems, the present invention receives a radio signal from a transmitter owned by a facility user by a door that is opened and closed by driving of a driving means and a receiving antenna provided on an entrance side of the door.

The control unit is arranged on a side farther from the door than the detection area of the human sensor, and the control means causes the human sensor to be in a non-energized state as the radio signal is captured by a receiving antenna. And summarized in that switching energized from.

  In the present invention, when a signal from a predetermined transmitter is captured by the receiving antenna and a facility user is specified, the human sensor associated with the driving device is switched from the non-energized state to the energized state. When the facility user enters the detection area of the human sensor in the energized state of the human sensor, that is, the operating state, the driving unit is operated by the control unit and the door is opened. For this reason, when a door is provided, for example, at the entrance of a room, the facility user can enter and exit with hands free. Further, the power consumption of the human sensor can be reduced, the running cost can be reduced, and the life of the human sensor can be extended.

  In the above configuration, it is desirable to overlap the detection area of the receiving antenna and the detection area of the human sensor. In this way, since the detection area of the receiving antenna and the detection area of the human sensor overlap, after the facility user is specified by the receiving antenna, the facility user is detected immediately by the human sensor, The door opens quickly. In this case, by adjusting the position and size of the overlapping range, facility users who do not intend to pass through the door are excluded, and only authorized facility users are appropriately selected and authenticated. The opening can be performed quickly.

In this way, the facility user is specified by the receiving antenna arranged on the exit side of the door, and when the facility user is detected by the human sensor, the closed door is opened and the facility is opened. The user can easily exit to the entrance side of the door.

  Further, in the above configuration, it is desirable that the human sensor is switched to a non-energized state as the facility user leaves the detection area of the receiving antenna on the exit side. In this way, since the human sensor is switched to the non-energized state as the facility user leaves the detection area of the receiving antenna on the exit side, the power consumption of the human sensor is reduced. Moreover, even if an unauthorized facility user passes in front of the door, the door will not be opened, so security can be ensured.

  In the above configuration, it is preferable to provide directivity with respect to detection of the receiving antenna of the receiving means. In this way, the detection area of the antenna can be set to be limited to, for example, the vicinity of the entrance of the door, and the facility user is prevented from inadvertently entering the detection area of the antenna. Opening and closing can be prevented.

  In the above-described configuration, the floor on the entrance side of the facility door is provided with a sign that allows visual confirmation of at least one of the detection area of the antenna of the receiver and the detection area of the human sensor. It is preferable. In this way, the detection range can be visualized and the facility user can be prevented from inadvertently entering the detection area of the antenna of the receiver, and the human sensor can be switched from the non-energized state to the energized operating state. Unnecessary switching operation and the like can be prevented.

Therefore, the slide door 16 has an inlet side on the right side and an outlet side on the left side in FIG. When the facility user moves from the right side of FIG. 1 to the left side, the left side is the entrance side and the right side is the exit side. When the facility user is far away from the slide door 16, the first and second human sensors 24 and 26 are maintained in a non-energized state.

  In FIG. 1, when the facility user moves to the right side of FIG. 1 along the passage 13 of the building and enters the detection area 21 of the first antenna 20, in step S (hereinafter simply referred to as S) 1 in FIG. A radio signal transmitted from the transmitter 18 carried by the facility user is received by the first antenna 20. The identification code 102 received by the first antenna 20 is transmitted to the server 42 through the LAN 41 shown in FIG. In S2, the files 101 and 111 shown in FIGS. 6 and 7 are referred to. In this reference, it is determined whether or not the passage permission of the position of the slide door 16 is set in the section 104 corresponding to the received identification code 102. This determination can also be executed by the controller 53A. In S3, when it is determined that the passage permission is not set, the control signal is not transmitted from the terminal 43 to the controller 53A, and the first human sensor 24 is held in a non-energized state. . Therefore, even if the facility user approaches the slide door 16, the first human sensor 24 does not detect the facility user, and the slide door 16 is kept closed.

In S8, it is determined whether or not the user, that is, the identification code 102 of the transmitter 18, has been detected by the second antenna 22. If YES is determined in S8, the sliding door 16 is closed in S9 as shown in FIG. At substantially the same time, in S10, the energization of the first and second human sensors 24 and 26 is stopped, and the first and second human sensors 24 and 26 are in a non-energized state.

  On the other hand, in the open door 31 shown in FIG. 2, the first and second human sensors 24 and 26 are always kept in an energized state. When the facility user moves from the left side to the right side in FIG. 2, the first human sensor 24 detects the facility user, and then the first antenna 20 captures a signal including the identification code 102 from the transmitter 18. Based on this, the terminal 43 determines whether or not the facility user is allowed to pass. As a result, if the facility user is given a passable section, the electric lock 32 is unlocked via the controller 53B. Accordingly, the facility user can open the opening door 31 by turning the door knob 34. When the facility user passes through the opening door 31 and closes the opening door 31 and exits from the detection area of the second antenna 22 and the second human sensor 26, the electric lock 32 returns to the locked state.
