Abnormal state monitoring system and abnormal state monitoring method

An abnormal state monitoring system comprising:

• a sensor information acquisition unit configured to acquire, from a sensor configured to detect a physical health state of a worker, sensor information indicating a detection result;
• a work check data holding unit configured to hold in advance, as work check data, an action of the worker assumed from a work procedure;
• an abnormality detection unit configured to detect an abnormality in work by comparing the sensor information with the work check data;
• a target side device provided in the vicinity of a work target, which is a target of the work, and/or the work target itself;
• and
• a management device configured to communicate with the target side device,
• wherein the target side device further includes a control unit configured to generate flag data including a flag indicating an abnormal level and state information indicating an abnormal state when the abnormality detection unit detects an abnormality, and transmit the flag data to the management device,
• wherein the management device transmits instruction information to at least one of the target side device, the worker, and the work target based on the flag data received from the target side device,
• wherein the flag data includes
• response level and state information for determining whether the physical health state of the worker is abnormal or influenced;
• importance information for determining whether a surrounding environment is influenced due to destruction or damage at a facility;
• and
• intervention information for determining whether intervention by an expert is necessary among remote instructions,
• wherein the importance information comprises a first importance state indicating a state of environmental destruction at the facility, a second importance state indicating a state of self-destruction at the facility, and a third importance state indicating a state of maintenance being required at the facility,
• wherein the management device is configured to transmit, when the flag data is received from the target side device, an instruction to acquire necessary sensing data to the target side device in accordance with an abnormal level of the flag data,
• wherein when the flag data indicates the first importance state, the management device is configured to request the target side device to obtain position coordinates of the worker and position coordinates of the facility using the sensor information acquisition unit, and
• wherein when the flag data indicates the second and third importance states, the management device is configured to request the target side device to obtain sound and temperature information at the facility using the sensor information acquisition unit.
