  In addition, each infrared light emitter 8 is not particularly limited. For example, as shown in FIG. 2, a position where a specific office worker or the like passes and detects the entrance / exit of a person, A plurality of places, for example, a passage serving as a virtual gate, a ceiling surface on the inside and outside of the gate, and the like, are arranged to electrically connect each infrared light emitter 8 and the controller CTL. Manage virtual gates, people approaching gates, the number of people, or the number of visitors.

  The tag T is formed as a name tag or a batch so that it can be easily carried or carried by a person, for example, a specific office worker or worker, and is attached to the chest or hung from the neck. The infrared ray emitted from the light emitter 8 can be received.

  As shown in FIG. 1, the tag T has a structure in which a light receiving photodiode 10 capable of receiving infrared light emission in one case and an optical signal received by the light receiving photodiode 10 are converted into a position ID. A receiving circuit 11 configured to do this, an ID combining circuit 12 configured to combine the position ID and the tag ID (unique ID), and a transmitting circuit 13 configured to combine the combined ID into a radio wave, for example, a radio signal. The radio signal having the combined ID is transmitted from the transmitting circuit 13 via the antenna 14.

The receiver 9 for receiving the radio signal transmitted from the tag T is not particularly limited. For example, the receiver 9 is disposed in the vicinity of the controller CTL and received by the antenna 15 of the receiver 9. The wireless signal is arranged and configured so that it can be input to the external I / O control circuit 3 of the controller CTL.
This single receiver 9 is designed to receive signals from a plurality of tags T and T at the same time. When there are a plurality of gates or virtual gates, one receiver 9 is arranged for each virtual gate. Each receiver 9 is electrically connected to the external I / O control circuit 3 of the controller CTL.
The transmission / reception of the radio signal is not particularly limited, but can be performed by, for example, RFID (Radio Frequency Identification).

In the embodiment shown in FIG. 1, the ID counter 16 and the number comparison circuit 17 are arranged outside the controller CTL and electrically connected to the controller CTL. The external I / O control circuit 3, the ID counter 16, the number comparison circuit 17 and the passing number counter 18 constitute a number counting circuit based on image analysis.

Next, the operation of the present invention will be described based on the first embodiment.
As shown in FIG. 2, an office worker, worker, etc. who carries or carries a tag T to which predetermined information or the like has been input is in a predetermined position or place, for example, an infrared light emitter 8 in a virtual gate, for example, When entering the infrared light receiving area irradiated from the light emitting LED, the position ID is always converted into an optical signal by the optical signal conversion circuit 4 in the virtual gate or the like, and infrared light is emitted from the light emitting LED of the infrared light emitter 8. Since the light is emitted, the position ID signal as the optical signal is received by the light receiving photodiode 10 of the tag T, the optical signal is converted into the position ID by the receiving circuit 11, and then the ID synthesizing circuit 12 A combined ID obtained by combining the position ID and the tag ID (unique ID) is transmitted from the transmission circuit 13 via the antenna 14 by radio waves, for example, radio signals.

The combined ID that is the radio signal is received by the antenna 15 of the receiver 9 and the received signal is transmitted to the external I / O control circuit 3 in the controller CTL. The received composite ID is analyzed by the ID conversion circuit 7 in the controller CTL, and the composite ID is decomposed into signals of position ID and tag ID (unique ID) and transmitted to the authentication determination circuit 2.
In the authentication determination circuit 2, authentication is determined by comparing the tag ID and the position ID with security information in the authentication database 5 using the key as a key, and the authentication result is used as a control signal by the control circuit 6 in the external I / O control circuit 3 In this case, if the authentication result is good (OK), an external device control instruction is issued from the authentication determination circuit 2, and this is sent to the external I / O control circuit 3 as a control signal by the control circuit 6. Then, a command to unlock the gate electric lock 19 attached to the gate or the virtual gate is issued.

However, in this case, since a camera CAM for image analysis is installed in the gate or virtual gate, images of all persons who do not pass through the gate or virtual gate are captured. These images are analyzed, and the number of people who pass through the image is authenticated, and this counted number is also transmitted to the external I / O control circuit 3.
The number of persons counted by this image analysis is input from the external I / O control circuit 3 to the number comparison circuit 17, and the number comparison circuit 17 receives the information obtained by counting the number of tags T in the external I / O control circuit 3, Since it is also obtained from the ID counter 16 via the ID conversion circuit 7, the tag number count obtained by the number comparison circuit 17 is compared with the image analysis number count obtained from the camera CAM. If the comparison results match, the external I / O control circuit 3 allows the person carrying the tag T to pass by unlocking the gate electric lock 19 attached to the gate or virtual gate.

  However, the tag count obtained by the external I / O control circuit 3 through the ID conversion circuit 7 and the ID counter 16 is compared with the image analysis count, and, for example, as shown in FIG. When the tag non-carrying person Mc is accompanied with the tag carrying persons Ma and Mb, the external I / O control circuit 3 recognizes that both pieces of information are inconsistent, and the authentication determination circuit 2, even if an external device control instruction is issued, the external device control instruction holds the gate electric lock 19 and operates the alarm device 20. Accordingly, when there is a tag non-carrying person, the passage of the gate or the virtual gate is blocked, and unauthorized entry of the tag non-carrying person Mc can be prevented in advance.

The alarm device 20 may be a bell or buzzer that emits an alarm sound, or a light emitter that emits strong light such as a patrol light. It is also possible to combine the bell or buzzer with a light emitter.
Further, in place of the electric lock 19 for the gate, it can be operated to record an image by the camera, or a color ball thrower can be adopted.

  Reception between the transmission circuit 13 of the tag T and the receiver 9 is not limited to a radio signal, but can be an optical signal. In this case, the transmitter circuit 13 emits infrared rays and the receiver 9 receives light.

  As mentioned above, although the accompanying prevention method in the entrance / exit management system of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, In the range which does not deviate from the meaning The configuration can be changed as appropriate.

  The sharing prevention method in the entrance / exit management system according to the present invention has a characteristic of detecting the number of passing people by comparing the authentication by the tag and the image analysis result by the camera. In addition to being suitable for use in prevention methods, for example, it can also be used in surveillance and crime prevention for sick persons and elderly people who are hesitant in hospitals and welfare facilities.

It is a flowchart which shows 1st Example of the accompanying prevention method in the entrance / exit management system of this invention. It is explanatory drawing of the accompanying prevention of this invention.
