FIG. 2 is a front view of the wireless tag 10a. The same applies to other wireless tags.
The wireless tag 10a is obtained by housing a circuit board 12a, a button battery, and the like in a flat case 11a made of plastic. An LED 13a is mounted on the circuit board 12a. The lighting of the LED 13a can be seen through the light emitting window 14a of the case 11a.

FIG. 3 is a configuration block diagram of the wireless tag 10a. The same applies to other wireless tags.
The wireless tag 10a switches transmission / reception between a microcomputer (microcomputer) 18a, a transmission unit 17a for wirelessly transmitting ID data given from the microcomputer 18a, and a reception unit 16a for wirelessly receiving a light emission instruction. The transmission / reception switching part 15a for this purpose and the LED 13a driven by the microcomputer 18a are provided.
The frequency of the transmission radio wave is, for example, 1 GHz, and the frequency of the reception radio wave is, for example, 1 MHz.

  Returning to FIG. 1, the management device 20 includes an information processing device 24 such as a computer, an ID data receiver 21 connected to the information processing device 24 via a network 25, and a receiving antenna 26 connected to the ID data receiver 21. A light emission instruction transmitter 22 connected to the information processing apparatus 24 via the network 25, a transmission antenna 27 connected to the light emission instruction transmitter 22, and a monitoring camera 23 connected to the information processing apparatus 24 via the network 25. It is composed of

The receiving antenna 26 is installed so as to form an ID data receiving area Er near the entrance of the passage.

The surveillance camera 23 is in the field of view from just below the transmitting antenna 27 to a place several meters in the passage. In addition, the section that enters the passage most in the field of view is the gate area Eg.
The gate area Eg can be blocked by the first gate G1 and the second gate G2.

  FIG. 4 is a flowchart showing the operation of the wireless tag 10a. This operation is activated by setting a button battery in the wireless tag 10a. The same applies to other wireless tags.

In step S1, the process proceeds to step S2 after waiting for a predetermined transmission cycle (for example, 3 seconds) or more from the start of transmission of the previous ID data (proceed immediately to step S2 at the time of activation).
In step S2, the transmission unit 17a is set in an operating state, and the transmission / reception switching unit 15a is set in transmission.
In step S3, ID data (identification data unique to the wireless tag 10a) is transmitted by radio waves.
In step S4, the transmission unit 17a is put into a dormant state.
In step S5, the receiving unit 16a is set in an operating state, and the transmission / reception switching unit 15a is set to receive.
In step S6, the time elapses with a reception timer provided in the microcomputer 18a.

In step S7, if the light emission instruction addressed to itself is not received by radio waves, the process proceeds to step S8, and if received, the process proceeds to step S10. Whether or not it is a light emission instruction addressed to itself is determined based on whether or not its own ID data is included in the header portion of the light emission instruction.
In step S8, if the reception timer has not reached a predetermined reception time (for example, 500 ms), the process returns to step S7, and if the reception time has been reached, the process proceeds to step S9.
In step S9, the receiving unit 16a is put into a dormant state. Then, the process returns to step S1.

  Here, the operation of steps S1 to S9 represents a basic operation in which ID data is repeatedly transmitted for each transmission cycle, and a light emission instruction can be received for a reception time for each transmission. Note that the number of transmissions may be counted so that the light emission instruction can be received for the reception time every several transmissions.

In step S10, reception is continued until reception of the light emission instruction addressed to itself is completed.
In step S11, the receiving unit 16a is put into a dormant state.

  Here, the operations of steps S10 and S11 reduce the reception time if the reception of the light emission instruction addressed to itself is completed within a time shorter than the predetermined reception time, and receive the light emission instruction addressed to itself within a time longer than the predetermined reception time. If completed, it represents an operation of extending the reception time.

  In step S12, the LED 13a is caused to emit light with a blinking pattern such as a Morse signal in accordance with the light emission pattern included in the light emission instruction. Then, the process returns to step S1.

FIG. 5 is a flowchart showing the operation of the wireless transmission / reception process of the management apparatus 20.
In step R1, the system waits for the ID data receiver 21 to wirelessly receive ID data, and if received, proceeds to step R2.

In step R2, if the ID data has already been determined to be “permitted” or “not permitted to pass” for the wirelessly received ID data, the process returns to step R1, and if it is newly received ID data, the process proceeds to step R3. .
In step R3, if the wirelessly received ID data is not registered as management target ID data, the process returns to step R1, and if it is registered ID data, the process proceeds to step R4.

In step R4, a light emission pattern is generated. For example, one of 8 types of light emission patterns prepared in advance is selected at random.
In step R5, a light emission instruction including the received ID data in the header portion and the generated light emission pattern in the content portion is wirelessly transmitted from the light emission instruction transmitter 22. Then, the process returns to step R1.

FIG. 6 is a flowchart showing the analysis processing operation of the management apparatus 20. This analysis process is executed in parallel with the above-described wireless transmission / reception process.
In step A1, a person in the monitoring area Em in the image taken by the monitoring camera 23 is individually extracted and the movement in the image is tracked. If a new person is extracted, it is determined that the person is “not permitted to pass”.
In step A2, if the emission of the wireless tag is not detected in the image, the process proceeds to step A3. If the emission is detected, the process proceeds to step A6.

In step A3, if a person being tracked in the image newly enters the gate area Eg, the process proceeds to step A4. If there is no new person, the process returns to step A1.
In step A4, if the person who newly enters the gate area Eg is determined to be “permitted”, the process returns to step A1, and if determined to be “not permitted to pass”, the process proceeds to step A5.

In step A5, an alarm signal is output. Then, the process returns to step A1.
For example, a red lamp is turned on by an alarm signal, an alarm sound is generated, and subsequent image recording is prohibited from being erased. Further, the gate area Eg is blocked by the first gate G1 and the second gate G2.

  In step A6, if the light emission pattern detected in the image is not the light emission pattern related to the light emission instruction transmitted immediately before, the process proceeds to step A5, and if it is the light emission pattern related to the light emission instruction, the process proceeds to step A7.

In step A7, face data registered corresponding to the ID data related to the light emission instruction transmitted immediately before is read out.
In step A8, if there is no face data registered corresponding to the ID data related to the light emission instruction transmitted immediately before, the process proceeds to step A5, and if there is, the process proceeds to step A9.
In step A9, the face of the person carrying the wireless tag whose emission is detected in the image is cut out by image processing, and is compared with the read face data to determine match / mismatch.
In step A10, if the faces do not match, the process proceeds to step A5, and if they match, the process proceeds to step A11.
In step A11, a person who possesses a wireless tag that detects light emission in the image is set as “permission permitted”. Then, the process returns to step A1.
