Details of the movement detection process (S11) will be described later.
- the control unit 50 determines whether the movement of the responder has been detected, that is, whether the worker W moving as the responder has been detected. It is determined whether or not (S12). When the control unit 50 determines that the movement of the respondent is not detected (NO in S12), the movement detection process (S11) is repeated at a predetermined detection cycle such as the transmission cycle of the position information by the worker terminal 4, for example.
- Step S13 corresponds to step S6 in FIG.
- the control unit 50 After sending the cancellation notice D6 (S13), the control unit 50 performs processing related to re-notification (S14-S17). Even if the abnormality notification system 1 detects the movement of the responder (YES in S12), the abnormal state may not be resolved, for example, because the responder does not reach the abnormal facility A2. Therefore, in the abnormality notification system 1 of the present embodiment, for example, when a predetermined period of time has passed without the abnormal state being resolved, processing is performed to re-notify each worker W of the abnormal state (S14 to S17).

- the control unit 50 holds the acquired state information in, for example, the temporary storage unit 51b.
- the control unit 50 determines whether a predetermined period of time has elapsed since, for example, the transmission of the cancellation notice D6 (S13) (S15).
- the predetermined period is set, for example, from the viewpoint of estimating the period required until the detected attendant arrives at the abnormal facility A2 and the abnormal state is resolved by dealing with the abnormal facility A2. If the predetermined period has not elapsed (NO in S15), the control unit 50 repeats acquisition of state information from the abnormal equipment A2 (S14).
- the control unit 50 determines whether the abnormal state has been resolved based on the state information acquired from the abnormal equipment A2 (S16). For example, when the status information D22 does not indicate an abnormality in the facility A2 after some time within the predetermined period, the control unit 50 determines that the abnormal state has been resolved.
- FIG. 9 shows a display example of re-notification on the worker terminal 4.
- the display unit 43 illustrated in FIG. 9 displays, for example, a message such as "re-NG" indicating that the abnormal state notified by the abnormality notification D3 has not been resolved, and a message indicating that the attendant has not arrived at the abnormal facility A2. is displayed.
- control unit 50 After sending the re-notification (S17), the control unit 50 repeats the processes after the movement detection process (S11).
- control unit 50 ends the processing shown in this flowchart without executing re-notification transmission (S17).
