Research on the Construction of Unsafe Behavior State Set of Workers Working at Altitude Based on IMU

The construction of high-rise buildings is difficult, especially the workers need to work at high altitude, which leads to a potential risk to the safety of workers. Thus, the protection of the life safety of workers at high altitudes has become the key production problem of high-rise building construction. To solve this problem, this paper first summarizes the construction behaviors of workers working at height and extracts the characteristics of unsafe behaviors of workers working at height. Then, the state set of unsafe behaviors is constructed and the preactions of dangerous actions of workers working at height are defined. Finally, based on the wearable inertial measurement unit and the quaternion bone model, the research on the behavior monitoring of the activities of workers working at height is carried out. The results show that the monitoring of workers' behavior at high altitudes can effectively reduce the danger at high altitudes.
