Next, a table diagram of the wireless communication system according to the embodiment of the present invention will be described with reference to FIG.
FIG. 2 shows the door-to-door information of the interactive door-to-door receiver 11 stored in the information collecting device 6.
The table of FIG. 2 shows the area number corresponding to the bidirectional door-to-door receiver ID, the representative name of the area, and the name of the installation location.
For example, the interactive door-to-door receiver ID “100” is associated with the area number “A”, the area representative name “blank”, and the installation location “Home”.

(Example 1, normal safety check)
Next, the operation of the wireless communication system according to the embodiment of the present invention will be described using FIG. FIG. 3 is a timing chart for explaining the operation of the wireless communication system according to the embodiment of the present invention.
FIG. 3 shows the display unit 31 of the information collection device 6, where the vertical axis of the display unit 31 is the bidirectional type door-to-door receiver ID and the horizontal axis is the time.
In FIG. 3, the detection invalid time 33 during which the setting for invalidating the detection is performed from 23:00 to 2 o'clock.
Although the human sensor 12 always detects the presence or absence of a human, transmission (answerback) to the host device is performed at predetermined time intervals. The transmission (answerback) time is set to 10 minutes, 30 minutes, 1 hour, etc. depending on the health condition of the resident.
For example, “XX-like house” with the interactive door-to-door receiver ID “100” performs answer back every 4 hours from 4 o'clock, and reference numeral 21 indicates that a person has reacted.

Since “XX-like house” of the bidirectional door-to-door receiver ID “145” is a person reaction at 34 o'clock after a person reaction at 4 o'clock, it is “abnormal” on the display unit 31 of the information collecting device 6. Is displayed.
The display on the display unit 31 such as “abnormal” is, for example, a case where there is no reaction of a person at the time of transmission (answerback). A predetermined time such as 3 hours may be set.
The display of “abnormal” or the like on the display unit 31 is a case where the “absence button” is not pressed on the safety confirmation button 13.

Next, the operation for confirming the safety at the normal time will be described with reference to the flowchart of FIG.
FIG. 4 is a normal flowchart for explaining the operation of the wireless communication system according to the embodiment of the present invention. When the user presses the button with the help of the bidirectional door-to-door receiver 11 (hereinafter also simply referred to as the door-to-door receiver 11), an emergency signal is transmitted from the door-to-door receiver 11 regardless of the processing of this flowchart. The information is transmitted to the collection device 6 and displayed on the information collection device 6, and emergency contact based on the table of FIG.

In FIG. 4, the information collection device 6 of the district broadcast facility normally collects the information of the person reaction from the door-to-side receiver 11 by polling at a predetermined time interval, for example, every several minutes to about 2 hours (401).
As a result of polling collection, when there is a person reaction response from the individual receiver 11 (YES in 402), the information collecting device 6 returns to Step 401. Note that the information collection device 6 preferably displays the information collection result by polling on the display unit 31.
On the other hand, when there is no person reaction response from the door-to-door receiver 11 (NO in 402), the information collecting device 6 determines whether or not there is an absence from the door-to-door receiver 11 (403).

  The person reaction response is automatically performed by the control unit (not shown) of the door-to-door receiver 11 based on the detection result of the human sensor 12. For example, if the human sensor 12 is an infrared sensor, the presence or absence of a sensor detection result is the presence or absence of a human reaction. When the human sensor 12 is a monitoring camera or an infrared camera, the presence / absence of a human reaction is determined depending on whether or not a human can be detected by image processing or the like in the human sensor 12 or the door-to-door receiver 11. However, in this case, a person is detected, but if the person does not move for a predetermined time, it is preferable to detect that there is no person reaction because the person may have fallen.

In addition, the information collecting device 6 determines whether or not there is an absence message by determining whether or not the absence button of the door-to-door receiver 11 is pressed by the resident. When the absence button of the door-to-door receiver 11 is pressed, the door-to-door receiver 11 voluntarily transmits information indicating that the user is away from the host station regardless of polling. The information collecting device 6 holds the information in a memory. Then, when the absence button is released, the door-to-door receiver 11 voluntarily transmits information indicating the absence of absence in the same way as described above, and the information collection device 6 performs the information on the individual door in the memory based on the information. The absence flag of the receiver 11 is deleted.
If the information collection device 6 has received an absence notification, the information collection device 6 returns to step 401 (YES in 403). On the other hand, if the absence notice has not been received (NO in 403), the information collecting device 6 determines whether there is no reaction for a predetermined time (404).

When there is no reaction for a predetermined time, the information collection device 6 displays a warning instruction on the display unit 31 (405), confirms the response of pressing the safety confirmation button 13, and if not pressed, the bidirectional type door-to-door Broadcast for safety confirmation is performed to the receiver 11 (406).
The information collection device 6 determines whether or not there is a response by the safety confirmation button 13 after the safety confirmation broadcast is performed (407), and if there is a response (YES in 407), returns to the above step 401, and if there is no response (NO in 407), an emergency contact (for example, XX fire brigade) is contacted (408), and the process is terminated.

(Example 2, confirmation of evacuation in case of disaster / emergency)
Next, the safety confirmation operation in an emergency will be described using the flowchart of FIG.
FIG. 5 is an emergency flowchart for explaining the operation of the wireless communication system according to the embodiment of the present invention.

The information collection device 6 of the district broadcasting facility collects the information of the person reaction from the door-to-door receiver 11 (hereinafter also simply referred to as the door-to-door receiver 11) by polling at a predetermined time interval, for example, every few minutes to about two hours. (502).

The information collection device 6 determines the presence / absence of a person reaction from the result of polling collection (503). If there is no person reaction from the individual receiver 11 (NO in 503), the information collection apparatus 6 returns to step 502. Note that the information collection device 6 preferably displays the information collection result by polling on the display unit 31.
On the other hand, if there is a person reaction or response from the individual receiver 11 (YES in 503), the information collecting device 6 displays a warning instruction on the display unit 31 (504), and proceeds to the processing in step 505.

The master station equipment 1 re-broadcasts the emergency broadcast (evacuation advisory) (505).
The information collection device 6 determines whether or not there is a person reaction or response (506). If there is no person reaction from the door-to-door receiver 11 (NO in 506), the process returns to step 502 and there is a person reaction or response. In the case (YES in 506), the process proceeds to step 507.
The information collection device 6 determines whether or not the master station facility 1 has re-broadcasted the emergency broadcast (evacuation advisory) a predetermined number of times (for example, 3 times) (507). If NO (507), the process returns to step 505, and if re-broadcasting reaches a predetermined number of times (YES in 507), contact the emergency contact (for example, XX fire brigade) (508) and process Exit.

  The wireless communication system according to the embodiment of the present invention can confirm the safety of a user.
