FIG. 4 is a flowchart for explaining a method for identifying a resident by the resident identification system according to Embodiment 1 of the present invention.

In step S1, when the activation of the active tag reader 2 is completed, the communication control unit 2e instructs the detection radio wave transmission unit 2b to transmit the detection radio wave of the active tag 1. Thereafter, in step S2, based on the instruction, the detected radio wave transmission unit 2b transmits the detected radio wave to the detected radio wave transmission antenna 2a. Thereafter, in step S3, it is determined whether or not there is a resident in the reading range of the active tag reader 2.

If there is no resident in the reading range of the active tag reader 2, the processing from step S1 is repeated. If there is a person in the radio wave range of the active tag reader 2, the process proceeds to step S4. In step S4, the detected radio wave receiving unit 1b decodes the detected radio wave received by the detected radio wave receiving antenna 1a, and outputs the decoded information to the communication control unit 1e.

Thereafter, in step S5, based on the decryption information, the communication control unit 1e instructs the response radio wave transmission unit 1d to transmit a response radio wave including the ID information of the active tag 1. Thereafter, in step S6, based on the instruction, the response radio wave transmission unit 1d causes the response radio wave transmission antenna 1c to transmit the response radio wave.

Thereafter, in step S7, the response radio wave receiving unit 2d decodes the response radio wave received by the response radio wave receiving antenna 2c and outputs the decrypted information to the communication control unit 2e. Thereafter, in step S8, based on the decryption information, the communication control unit 2e extracts the ID information of the active tag 1, and outputs the ID information to the tag authentication unit 2g.

Thereafter, in step S9, the tag authenticating unit 2g compares the ID stored in the tag ID database 2f with the ID information of the active tag 1 to determine the type of the owner of the active tag 1. Thereafter, the tag authenticating unit 2g notifies the discrimination information to a higher-level device such as the lighting management device 4 or the air conditioning management device 6. After the notification, the processing from step S1 is repeated.

If the ID corresponding to the ID information of the active tag 1 is not stored in the tag ID database 2f, the tag authentication unit 2g notifies the host device of the presence of the suspicious person. After the notification, the processing from step S1 is repeated.

Next, a method for detecting the number of people will be described with reference to FIG.
FIG. 5 is a flowchart for explaining a method of detecting the number of persons by the resident identification system according to Embodiment 1 of the present invention.

In step S11, when the camera 3 is activated, the imaging unit 3a starts imaging in the field and outputs the captured image to the image analysis unit 3b. Thereafter, in step S12, the image analysis unit 3b detects the number of people present in the captured image and outputs information regarding the number of captured people to the communication control unit 3c. Thereafter, in step S13, the communication control unit 3c compares the number of captured people with the previous time.

If the number has not changed, the process proceeds to step S14. In step S14, the communication control unit 3c determines whether or not a certain time has elapsed. If the certain time has not elapsed, the processing from step S11 is repeated.

If the number of people has changed in step S13 or if a certain time has passed in step S14, the process proceeds to step S15. In step S15, the communication control unit 3c notifies information related to the number of persons to be photographed to a higher-level device such as the lighting management device 4 and the air conditioning management device 6. After the notification, the processing from step S11 is repeated.

Next, a method for controlling the illumination 5 will be described with reference to FIG.

In step S21, the lighting management device 4 compares the number of authentications of the active tag 1 of the active tag reader 2 and the number of photographers of the camera 3 as a comparison unit.

If the number of authenticated active tags 1 is less than the number of photographers, the process proceeds to step S22. In step S22, the lighting management device 4 controls the lighting 5 to blink. The lighting management device 4 notifies the security system 8 of an alarm. Thereafter, the processing is repeated from step S21.

If it is determined in step S21 that the number of active tags 1 is the same as the number of images taken by the camera 3, the process proceeds to step S23. In step S23, based on the collation information of the active tag reader 2, the lighting management device 4 determines whether or not a suspicious person is included.

When a suspicious person is included, it progresses to step S22 and lighting control of the illumination 5 and notification of an alarm are made. If no suspicious person is included, the process proceeds to step S24. In step S24, based on the collation information of the active tag reader 2, the lighting management device 4 determines whether or not a visitor is included.

If a visitor is included, the process proceeds to step S25. In step S25, the illumination management device 4 controls the illumination 5 to be lit brightly. Thereafter, the processing from step S21 is repeated.

If the visitor is not included in step S25, the process proceeds to step S26. In step S26, based on the collation information of the active tag reader 2, the lighting management device 4 determines whether or not a business traveler is included.

If a business traveler is included, the process proceeds to step S27. In step S27, the illumination management device 4 controls the illumination 5 to be lit dark. Thereafter, the processing from step S21 is repeated.

If the business traveler is not included in step S26, only employees are authenticated. In this case, the process proceeds to step S28. In step S28, the lighting management device 4 controls the lighting 5 to be turned off. Thereafter, the processing from step S21 is repeated.

FIG. 7 is a flowchart for illustrating the air conditioning control method by the occupant discrimination system according to Embodiment 1 of the present invention.

In step S31, the air-conditioning management device 6 compares the number of authentications of the active tag 1 of the active tag reader 2 and the number of people captured by the camera 3 as a comparison unit.

If the number of authenticated active tags 1 is less than the number of photographers, the process proceeds to step S32. In step S <b> 32, the air conditioning management device 6 controls to stop the air conditioning 7. Thereafter, the processing is repeated from step S31.

If it is determined in step S32 that the number of active tags 1 is the same as the number of images taken by the camera 3, the process proceeds to step S33. In step S33, based on the collation information of the active tag reader 2, the air conditioning management device 6 determines whether a suspicious person is included.

When a suspicious person is included, it progresses to step S32 and stop control of the air conditioning 7 is made. If no suspicious person is included, the process proceeds to step S34. In step S34, based on the collation information of the active tag reader 2, the air conditioning management device 6 determines whether or not a visitor is included.

If a visitor is included, the process proceeds to step S35. In step S35, the air conditioning management device 6 performs control so that the air conditioner 7 is strongly operated. Thereafter, the processing from step S31 is repeated.

If the visitor is not included in step S35, the process proceeds to step S36. In step S36, based on the collation information of the active tag reader 2, the air conditioning management device 6 determines whether or not a business traveler is included.

If a business traveler is included, the process proceeds to step S37. In step S37, the air conditioning management device 6 performs control so that the air conditioning 7 is operated weakly. Thereafter, the processing from step S31 is repeated.

If the business traveler is not included in step S36, only the employee is authenticated. In this case, the process proceeds to step S38. In step S38, the air conditioning management device 6 controls the air conditioning 7 to stop. Thereafter, the processing from step S31 is repeated.

According to the first embodiment described above, the number of authenticated active tags 1 is compared with the number of photographed cameras 3. A suspicious person is detected when the number of authentications of the active tag 1 is smaller than the number of persons photographed by the camera 3. For this reason, the number of suspicious persons can be grasped. As a result, security is improved.

Further, when the ID corresponding to the ID information of the active tag 1 is not stored in the tag ID database 2f, a suspicious person is detected. For this reason, for example, a suspicious person possessing an inappropriate active tag 1 can be detected.

Also, when a suspicious person is detected, the illumination 5 blinks. For this reason, it becomes easy for a suspicious person to find. As a result, security is improved.

Also, the control of the illumination 5 changes according to the type of ID information. For this reason, the type of resident is known to the surroundings. As a result, it is possible to thoroughly deal with the visitors (for example, greetings and talks). Also, unnecessary power consumption in the hall can be reduced.

Also, if a suspicious person is detected, the air conditioner 7 stops. For this reason, the environment of the place where a suspicious person exists can be deteriorated.

Also, the control of the air conditioner 7 changes according to the type of ID information. For this reason, unnecessary power consumption in the hall can be reduced.

As described above, the presence determination system according to the present invention can be used for a system for detecting a suspicious person.
