[Operation of wireless communication system]
Next, the operation of the wireless communication system according to Embodiment 1 of the information communication system of the present invention will be described with reference to FIG. FIG. 3 is a time chart showing an example of operation in the wireless communication system according to the first embodiment of the information communication system of the present invention.

For example, when an administrative organization such as a municipality receives a search request for an elderly person from a resident, the center station apparatus 10 determines the elderly person who is a recognized person obtained from the requester of the search request. By inputting the item information for determination to input from the input unit 207 of the console 2, the item information for determination is registered in the recognized person information table 209b of the recording unit 209, and information of the recognized person is registered. (Step S101).
Here, the item information for determination for determining the person to be recognized is, for example, age, gender, clothes (shape, color), hairstyle, hair color, etc., and each feature amount is the person-to-be-recognized person information table 209b. Registered in For example, these registration methods may be set so that they can be selected on the operation screen displayed on the display unit 208 by an operation from the input unit 207.

Next, regarding the search for an elderly person who is a recognized person, the operator determines whether or not loudspeaker broadcasting is necessary (step S102). If it is determined that it is necessary (YES), the process of the next step S103 is performed. If it is determined that it is unnecessary (NO), the process proceeds to the process of step S108 without performing loud sound broadcasting.
Here, for example, when the person to be searched is a suspicious person or the like, the search by the camera 35 of the terminal station device 30 is necessary without making it public, so it is better not to perform loud broadcasting.

When it is determined in step S102 that loudspeaker broadcasting is necessary, in the center station device 10, the center station control unit 201 of the console 2 uses the loudspeaker broadcast text generation function 201a to determine an elderly person who is a recognized person. Based on the item information for determination, a text for a loud sound broadcast is generated (step S103).
Next, the center station control unit 201 uses the voice conversion function 201b to convert the text for the loud sound broadcast into the sound data for the loud sound broadcast (step S104). The converted audio data for the loudspeak broadcast is transmitted to the designated or all the terminal station devices 30 and / or the individual receivers 40 (step S105).
Then, when the terminal station device 30 receives the sound data for the loudspeaker broadcast from the center station device 10, the terminal station device 30 performs the loudspeak broadcast of the sound for the loudspeaker broadcast from the trumpet speaker 34 (step S106). When the broadcast audio data is received, the sound for the loudspeak broadcast is output from the monitor speaker 42 (step S107).

The center station control unit 201 of the console 2 transmits the item information for determination of the recognized person and the image collection start request regarding the recognized person to the terminal station apparatus 30 via the base station wireless transmission / reception apparatus 1 ( Step S108).
When the terminal station device 30 receives from the center station device 10 the item information for the person to be recognized and the image collection start request for the person to be recognized, the terminal station device 30 operates the camera 35 to start image acquisition and image analysis processing. The image acquired by the image acquisition unit 36 is analyzed by the image analysis unit 37, and the person to be recognized is detected (step S109).
In the image analysis processing in step S109, for example, a person search for a person to be recognized is performed using a known technique disclosed in Japanese Unexamined Patent Application Publication No. 2009-199322 and the like. Japanese Patent Application Laid-Open No. 2009-199322 describes a technique for searching for a person from facial feature amounts and clothing information.
Then, the camera 35 of the terminal station apparatus 30 accumulates and stores the image of the person to be recognized and the image related information detected in the image analysis process in step S109 in a storage unit (not shown) (step S110).

On the other hand, in the center station apparatus 10, when the operator makes an image transmission request to the terminal station apparatus 30 by the polling function from the input unit 207 of the console 2 (step S111), the terminal station apparatus 30 is recognized. The person's image and the image related information are transmitted to the center station apparatus 10 through the wireless line 21 together with the detection time and the terminal station ID (step S112).
In the center station device 10, when the base station wireless transmission / reception device 1 receives the image of the person to be recognized and the image-related information from the terminal station device 30, the center station device 10 transfers them to the console 2, and the center station control unit 201 of the console 2 stores the information. The information is stored and stored in the person-to-be-recognized person information table 209b of the unit 209 (step S113).
The center station control unit 201 analyzes the images of the plurality of persons to be recognized and the image related information collected from the terminal station device 30 (step S114), and displays the analysis results on the display unit 208 (step S115). For example, the center station control unit 201 specifies the image of the recognized person and the location where the recognized person is found on the map of the operation screen displayed on the display unit 208 based on the analysis result.

Next, the operator is made to determine whether or not a loud sound broadcast is necessary for the fact that a recognized elderly person is found (step S116). If it is determined that it is necessary (YES), the next step S117 is performed. If it is determined that the process is unnecessary (NO), the process is terminated without performing loud sound broadcasting.
Here, for example, if the person being searched is a suspicious person, etc., it may be better not to make it public. do it.

When it is determined in step S116 that loudspeaker broadcasting is necessary, in the center station device 10, the center station control unit 201 of the console 2 uses the loudspeaker broadcast text generation function 201a based on the image of the person to be recognized and the image related information. Thus, a text for a loud sound broadcast is generated (step S117).
Next, the center station control unit 201 uses the voice conversion function 201b to convert the text for the loudspeak broadcast into voice data for the loudspeak broadcast (step S118). The converted audio data for the loudspeak broadcast is transmitted to the designated or all the terminal station devices 30 and / or the individual receivers 40 (step S119).
When the terminal station device 30 receives the sound data for the loudspeaker broadcast from the center station device 10, the terminal station device 30 performs the loudspeak broadcast of the sound for the loudspeaker broadcast from the trumpet speaker 34 (step S120). When the broadcast audio data is received, the sound for the loudspeak broadcast is output from the monitor speaker 42 (step S121).

  In the processing of step S102 and step S116, the operator determines whether or not the loudspeaker broadcasting is necessary, but the center station control unit 201 may automatically determine it. In that case, whether or not the loudspeaker broadcast is required for each person to be recognized is set in the person-to-be-recognized person information table 209 b, and the center station control unit 201 refers to the person-to-be-recognized person information table 209 b in the storage unit 209. Judgment is made according to the setting of whether or not broadcasting is necessary.

  As described above, according to the first embodiment of the present invention, it is possible to directly contribute to the search for a recognized person such as an elderly person or a suspicious person, and more accurately and more accurately based on information on the detected recognized person. Information can be provided promptly.

For example, the center station control unit 201 specifies the image of the recognized person and the location where the recognized person is found on the map of the operation screen displayed on the display unit 208 based on the analysis result.

Next, regarding the finding of the elderly person who is the person to be recognized, the operator is made to determine whether or not the loud sound broadcasting is necessary (step S415), and when it is determined that it is necessary (YES), the next step S416 is performed. If it is determined that the process is unnecessary (NO), the process is terminated without performing loud sound broadcasting.
Here, for example, if the person being searched is a suspicious person, etc., it may be better not to make it public. do it.

If it is determined in step S415 that loudspeaker broadcasting is necessary, in the center station device 10, the center station control unit 201 of the console 2 uses the speech generation function for the loudspeaker broadcast (not shown) and the image of the person to be recognized. Based on the information, voice data for the loudspeak broadcast is generated (step S416), and the converted voice data for the loudspeak broadcast is transmitted to the designated or all the terminal station devices 30 and / or the individual receivers 40. (Step S417).
When the terminal station device 30 receives the sound data for the loudspeaker broadcast from the center station device 10, the terminal station device 30 performs the loudspeak broadcast of the sound for the loudspeaker broadcast from the trumpet speaker 34 (step S418). When the broadcast audio data is received, the sound for the loudspeak broadcast is output from the monitor speaker 42 (step S419).

  In the processing of step S402 and step S415, the operator determines whether or not the loudspeaker broadcasting is necessary, but the center station control unit 201 may automatically determine it. In that case, whether or not the loudspeaker broadcast is required for each person to be recognized is set in the person-to-be-recognized person information table 209 b, and the center station control unit 201 refers to the person-to-be-recognized person information table 209 b in the storage unit 209. Judgment is made according to the setting of whether or not broadcasting is necessary.

As described above, according to the third embodiment of the present invention, it is possible to directly contribute to the search for a recognized person such as an elderly person or a suspicious person. Information can be provided promptly.
Also, when the person to be recognized is detected by the terminal station device, the center station device automatically generates voice data for loudspeaker broadcasting, and can be loudspeaked by the terminal station device and the door-to-door receiver. Can inform information.

  As mentioned above, although this invention has been demonstrated using several embodiment, it is not limited to these embodiment. For example, the image analysis function for detecting the person to be recognized is provided in the camera in the present embodiment. However, an image processing apparatus separate from the camera may be provided, or may be provided on the center station apparatus side. Good. In addition, the text generation function and the voice conversion function may be provided in the same medium, or may be provided in different media.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments.
