In the energy industry, equipment is cracked, leaked and even forced to stop due to abnormal stress or displacement of a hanging device. At present, the load and displacement of the elastic hanging device are inspected usually by looking at a load and a displacement pointer regularly, and the rigid suspender device is inspected usually by roughly judging through manual shaking or attaching a strain gauge on a suspender to measure and adjust the load. Its disadvantages are represented by: (1) the load and displacement of the hanging device cannot be monitored in real time, and the load or displacement is out of limit, so that real-time warning cannot be given. (2) The problems of inaccurate load and displacement detection exist in visual inspection and shaking inspection. (3) The method of pasting the strain gauge is adopted for measurement, the measurement precision is greatly influenced by temperature, humidity and pasting quality, and the efficiency is extremely low. (4) The hanging device needs to be unloaded during strain gauge measurement, and the rigid hanging device cannot be unloaded in a thermal state, so that thermal state bearing data cannot be obtained, namely the instantaneity is poor.
