Stores the number of times included. Thereafter, every time the notification broadcast receiver 3 transmits a detection signal to the center device 1 at a predetermined time interval, the center device 1 executes the same storing process, and the number of times is accumulated in the input history DB 15a each time. As a result, the number of sensor detections, which is the accumulated value of the number of times, can be stored in the input history DB 15a.

  As shown in FIG. 6, first, the control unit 39 of the notification broadcast receiver 3 stands by until the above-described predetermined timing arrives (SA1, No). Specifically, the control unit 39 of the notification broadcast receiver 3 monitors whether or not the communication unit 30 of the notification broadcast receiver 3 has received the input promotion signal transmitted from the communication unit 17 of the center device 1. When it is determined that the input promotion signal has been received, it is determined that a predetermined timing has arrived. And when it determines with the predetermined | prescribed timing having come (SA1, Yes), the control part 39 of the notification broadcast receiver 3 promotes the input of the energy switch 37a with respect to a subject by lighting the lighting part 42. (SA2).

  Next, the control unit 18 of the center apparatus 1 stores the input standby information in association with the item of the current date in the input history DB 15a (SA3). Specifically, the current date (in this embodiment, it is assumed that it is October 17) is acquired by a known method, and the acquired current date and input standby information are stored in all receiver IDs. Correspondingly, it is stored in the input history DB 15a. The input history information stored in the input history DB 15a in this way is displayed on the display of the center device 1 as shown in FIG. Therefore, after the processing of SA3, the input standby information symbol “triangle” is displayed on the left side of the column corresponding to the item of the current date on the display of the center device 1.

  Next, the input information acquisition unit 18a of the center device 1 determines whether or not there is an input from the energy switch 37a (SA4). Specifically, when the input by the spirit switch 37 a is performed, the control unit 39 of the notification broadcast receiver 3 generates an input signal including the receiver ID of the notification broadcast receiver 3 to generate the center device 1. Send to. And the input information acquisition part 18a of the center apparatus 1 determines with having input by the energy switch 37a, when this input signal is received. In particular, in the present embodiment, it is assumed that a plurality of modes of the first mode and the second mode can be performed as modes of input by the energy switch 37a. Among these, the “first mode” is a mode for notifying that the target person is well, for example, a mode in which the spirit switch 37a is input only once. The “second mode” is a mode for notifying a predetermined state other than the first mode, for example, a mode in which the subject is aware of his / her condition abnormality and seeks help from others. It is assumed that the energy switch 37a is continuously input for a predetermined time or longer.

  And when the communication part 17 has not received the 1st input signal or the 2nd input signal, the input information acquisition part 18a of the center apparatus 1 determines with there being no input (SA4, No), and performs an input reception process. It is determined whether a predetermined time has elapsed from the start (SA5), and the processes of SA4 and SA5 are repeatedly executed until the predetermined time elapses (SA5, No).

  And when the communication part 17 receives a 1st input signal or a 2nd input signal, it determines with having input (SA4, Yes), and the state abnormality determination part 18b is the energy switch 37a by a 1st aspect. Is determined (SA6). Specifically, when it is determined that the received input signal is the first input signal, it is determined that the energy switch 37a is input according to the first aspect, and the received input signal is the second input signal. When it determines, it determines with the energy switch 37a having been input by the 2nd aspect.

  And when it determines with the energy switch 37a having been input by the 1st aspect (SA6, Yes), the input information acquisition part 18a analyzes the said input signal, and specifies receiver ID contained in the said input signal. Then, the input information acquisition unit 18a replaces the input waiting information stored in association with the item of the current date in the record of the receiver ID of the specified notification broadcast receiver 3 in the input history DB 15a. And the input confirmation information symbol “double circle” is displayed instead of the input standby information symbol “triangle” on the left side of the column corresponding to the item of the current date on the display of the center device 1 (SA7). For example, the owner of the receiver ID 001 and the receiver ID 003 shown in FIG. 3B is the person who performed the input of the energy switch 37a because the input confirmation information symbol is displayed in the field. Finally, the lighting unit 42 lit in SA2 is turned off (SA8), and the input receiving process is terminated.

  On the other hand, when it is determined that the energy switch 37a is not input according to the first aspect (SA6, No), that is, when it is determined that the energy switch 37a is input according to the second aspect, the speaker of the center device 1 (illustrated) A predetermined alarm is output from (omitted) (SA9), the lighting unit 42 is turned off (SA8), and the input acceptance process is terminated. The specific content of the alarm output is arbitrary. For example, the alarm signal is transmitted from the center device 1 to the notification broadcast receiver 3 that has transmitted the second input signal, and the notification broadcast receiver that has received the alarm signal is received. Alarm output may be performed from the speaker 34 provided in the third stage. Further, an alarm signal is transmitted to the other notification broadcast receiver 3 other than the notification broadcast receiver 3 that has transmitted the second input signal, and an alarm is output from the speaker 34 provided in the other notification broadcast receiver 3. By performing the above, it is possible to prompt the owner of the other notification broadcast receiver 3 to confirm whether or not the target person has a state abnormality. For example, the notification broadcast receiver 3 of the other target person who requests confirmation of the abnormality when the abnormality occurs in each target person and the receiver ID, name, and address of the notification broadcast receiver 3 of each target person. The subject-related table configured by associating the receiver ID, name, and address with each other is stored in the memory 15 in advance. Then, the receiver ID, name, and address of another subject are acquired with reference to the target person related table, and an alarm signal including the acquired receiver ID, name, and address is generated and transmitted. Request confirmation from other subjects. At this time, by outputting the name and address of the subject in which the abnormality has occurred from the notification broadcast receiver 3 of the other subject, it is possible to identify the subject in which the abnormality has occurred.

  If the predetermined time has passed without input by the energy switch 37a (SA5, Yes), it is determined that there is no input by the energy switch 37a on that day, and the lighting unit 42 is turned off (SA8). To finish the input acceptance process.

(Determination process)
Next, a determination process executed by the notification broadcasting system 100 will be described. FIG. 7 is a flowchart of the determination process. The execution timing of this determination process is arbitrary. For example, it may be executed immediately after the above-described input reception process is completed, may be executed at a predetermined time on each day, or may be performed by an administrator. (For example, timing when the administrator clicks a determination process activation icon (not shown) displayed on the display of the center device 1).

  First, the state abnormality determination unit 18b of the center device 1 acquires the input history information stored in the input history DB 15a (SB1). Then, the presence / absence of the notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days is determined (SB2). As this predetermined number of days, since it is not continuously confirmed that the input by the energy switch 37a has been performed, a number that can be estimated that there is a high possibility that a state abnormality has occurred in the subject is set. Although the specific number is arbitrary, for example, the predetermined number of days is 3 days. In this way, by determining the presence or absence of the notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days in succession, it is possible to identify the notification broadcast receiver 3 that is likely to have a state abnormality in the target person. Is possible.

  Here, as shown in FIG. 3A, the notification broadcast receiver 3 with the receiver ID 002 stores the input standby information continuously for three days from October 15 to October 17. Therefore, the state abnormality determination unit 18b determines that there is the notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days continuously. If it is determined that there is a notification broadcast receiver 3 in which input standby information is stored continuously for a predetermined number of days (SB2, Yes), the number of sensor detections for the predetermined number of days in the notification broadcast receiver 3 is equal to or less than the predetermined number. Whether or not (SB3). As the predetermined number of days and the predetermined number of times, the number of days and the number of times that it is possible to estimate that there is a high possibility that a condition abnormality has occurred in the target person because the movement of the target person has not been detected more than a specific number of times in a specific period However, in the present embodiment, the predetermined number of days is set as three days, and the predetermined number of times is set as three.

  Here, as shown in FIG. 3A, in the notification broadcast receiver 3 having the receiver ID 002, the number of sensor detections is 3 times or less in any of the three days from October 15 to October 17. It is. Therefore, the state abnormality determination unit 18b determines that the number of sensor detections for a predetermined number of days is equal to or less than the predetermined number. If it is determined that the number of sensor detections for the predetermined number of days is equal to or less than the predetermined number (SB3, Yes), the state abnormality determination unit 18b determines that there is a high possibility that the target person has a state abnormality, and the predetermined number of days. Is changed to non-input information (SB4). Specifically, the state abnormality determination unit 18b is an input standby information symbol stored in association with the receiver ID of the notification broadcast receiver 3, and is associated with each date included in the predetermined number of days. In place of the stored input standby information symbol, the non-input information is stored. On the left side of the column corresponding to each date on the display of the center device 1, the input standby information symbol “triangle” is replaced with the non-input information “ "X" is displayed.

  Then, in order to confirm the safety of the subject, an email is transmitted to the subject, the relative of the subject, etc. (SB5). Specifically, an address table (not shown) stored in association with the subject's name and the mail address of the subject or the relative of the subject is stored in advance in the memory 15 and the address table is referred to. The mail address is specified, the mail is automatically transmitted to the specified mail address, and the determination process is terminated. In this embodiment, in order to confirm the safety of the subject, an email is automatically transmitted to the subject, the relative of the subject, etc., but the safety may be confirmed by other methods. . For example, the administrator may actively contact the subject's telephone number or the like, or the staff may directly visit the subject's dwelling unit.

  On the other hand, when it is determined that there is no notification broadcast receiver 3 in which the input standby information is stored continuously for a predetermined number of days (SB2, No), or when it is determined that the number of sensor detections for the predetermined number of days is not less than the predetermined number (SB3, No), the non-output signal number determination unit 18c acquires the number of non-output signals (SB6). Specifically, first, the non-output signal number determination unit 18c acquires the receiver ID of the notification broadcast receiver 3 subjected to the determination from the input history DB 15a, and outputs the unoutput including the acquired receiver ID. A signal number request signal is generated, and the generated non-output signal number request signal is transmitted to the notification broadcast receiver 3 via the communication unit 17. And the control part 39 of the notification broadcast receiver 3 which received this non-output signal number request signal analyzes the received non-output signal number request signal, and sets receiver ID contained in the non-output signal number request signal. It is determined, and it is determined whether or not the specified receiver ID matches its own receiver ID, and the number of unoutput signals is transmitted only when it matches. Specifically, the control unit 39 of the notification broadcast receiver 3 refers to the information stored in the notification broadcast signal storage unit 40a of the memory 40 and specifies the number of unoutput signals. Then, a response signal including the number of non-output signals and its own receiver ID is transmitted to the broadcast center via the communication unit 30 of the notification broadcast receiver 3. And the non-output signal number determination part 18c of a broadcast center analyzes this response signal, and specifies receiver ID contained in the said response signal, and the number of non-output signals.

  Next, the non-output signal number determination unit 18c compares the number of non-output signals acquired in SB6 with a predetermined number stored in the memory 15 of the center device 1, and determines whether or not the number of non-output signals exceeds the predetermined number. Is determined (SB7). As this predetermined number, since the notification broadcast signal is not output, a number that can be estimated that the target person is likely to have a state abnormality is set, and the specific number is arbitrary. For example, five are set. If it is determined that the number of non-output signals exceeds the predetermined number (SB7, Yes), the state abnormality determination unit 18b determines that there is a high possibility that the subject has a state abnormality. In order to confirm safety, an e-mail is transmitted to the target person, a relative of the target person, etc. (SB5). Note that a specific method of transmitting mail can be performed in the same manner as the processing of SB5 described above, and thus detailed description thereof is omitted.

  On the other hand, when it is determined that the number of non-output signals does not exceed the predetermined number (SB7, No), the state abnormality determination unit 18b determines that the target person is unlikely to have a state abnormality, and ends the determination process. To do.

(Correspondence result storage processing)
Next, the correspondence result storage process executed by the notification broadcasting system 100 will be described. FIG. 8 is a flowchart of the correspondence result storage process. This correspondence result storing process is roughly information indicating the means by which the administrator actually confirmed the safety of the target person after confirming the safety of the target person in SB5 of FIG. Is a process for storing in the memory 15 of the center device 1. The execution timing of the correspondence result storage process is arbitrary, and in this embodiment, the notification broadcast reception in which the administrator executes the correspondence result storage process in the input history table shown in FIG. 3 displayed on the display is received. This is executed when the receiver ID column of the machine 3 is clicked.

  First, the state abnormality determination part 18b acquires a correspondence result (SC1). As a specific method for acquiring the correspondence result, for example, there is a method of receiving an input of the correspondence result from the administrator. In other words, when the administrator clicks on a column in the display where the input standby information symbol is stored, a check list indicating various correspondence results is displayed on the display. The contents of this checklist are arbitrary, but in this embodiment, “contact from the person”, “contact from the family”, “contact from the neighborhood”, “the staff meets the person”, and “the staff "Family and visit" and "Other" items are displayed. Then, when the administrator clicks an item corresponding to the actual correspondence result from these items and checks it, the state abnormality determination unit 18b can obtain the correspondence result. In addition, when the administrator checks the “other” item, the administrator can input a specific response result, and the state abnormality determination unit 18b inputs the response result input in this way. Can be acquired.

  Next, the control unit 18 of the center device 1 changes the non-input information of the item corresponding to the clicked field to the confirmed information (SC2). Specifically, the control unit 18 stores the confirmed information in place of the non-input information stored in association with the receiver ID of the specified notification broadcast receiver 3 in the input history DB 15a. As shown in (c), the confirmed information symbol “square” is displayed on the display of the center apparatus 1 in place of the uninput information symbol “X”. This completes the correspondence result storage process. The administrator can confirm the specific contents of the correspondence result by clicking again on the column in which the confirmed information is stored.

(effect)
As described above, according to the present embodiment, it is determined whether or not the subject has a state abnormality based on the presence or absence of the subject's active action such as input by the subject's spirit switch 37a. Compared to an anomaly detection system that uses a sensor, for example, the possibility of misjudging that the subject has no state abnormality based on the presence of a dynamic object (eg, a pet) other than the subject can be reduced. The accuracy of detection can be increased, and the existing notification broadcast receiver 3 is used, so that a system can be constructed at a low cost.

  Further, by promoting the input at a predetermined timing when the input by the energy switch 37a should be promoted for the subject, it is possible to reduce the possibility that the subject forgets the input by the energy switch 37a. It becomes possible to further improve the accuracy of detection.

  Also, by determining whether there is an abnormality in the subject's condition according to the number of notification broadcast signals that have not been output, the situation where the subject has accumulated without outputting the announcement broadcast signal is reflected in the determination of abnormality detection. Therefore, it is possible to further increase the accuracy of abnormality detection.

  In addition, by determining the presence or absence of the subject's state abnormality based on the input history information, it is possible to reflect the input state or the like of the subject's normal energy switch 37a in the abnormality detection determination. It becomes possible to further improve the accuracy of detection.

  Moreover, when the input by the energy switch 37a is performed according to the first aspect, it is determined that the subject does not have a state abnormality, and the input by the energy switch 37a is performed according to the second aspect different from the first aspect. In this case, by determining that the subject has a state abnormality, the state abnormality determination can be performed in various modes. In addition, since it is possible to output both the presence and absence of a state abnormality by a single energy switch 37a, it is possible to construct a system at a lower cost than when a plurality of input means are provided. It becomes.
