# Abnormal state monitoring system and abnormal state monitoring method

## Abstract

Work efficiency and quality are improved. The invention includes: a sensor information acquisition unit configured to acquire, from a sensor configured to detect a 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; and an abnormality detection unit configured to detect an abnormality in work by comparing the sensor information with the work check data. Further, a control unit is provided that is 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. A management device transmits instruction information based on the flag data.
