Abstract

The invention discloses a displacement and vibration monitoring device, comprising a frame, a measuring mechanism and a sensing mechanism; the frame is arranged on the object to be measured; the measuring mechanism is arranged on the frame, and can measure the displacement parameters and vibration parameters of the object to be measured. Monitoring; the sensing mechanism is arranged on the frame, and includes a telescopic assembly and a sensing element; the telescopic assembly is in contact with the measuring mechanism and can move with the action of the measuring mechanism. The technical scheme of the present invention is applied, and a combination of a measuring mechanism and a sensing mechanism is adopted, and the effect is: the threshold value of the vibration of the object to be measured is monitored by the sensing mechanism, so that the sensing mechanism controls the measuring mechanism to increase the sampling frequency of displacement, and the object to be measured can be effectively treated in real time. The displacement parameters and vibration parameters are monitored.

Description

technical field [0001] The invention relates to the field of safety monitoring, in particular to a displacement and vibration monitoring device. Background technique [0002] In the field of structure safety monitoring, the analysis and judgment of the safety status of the structure is mainly based on the changes of the measured parameters. At present, the commonly used measurement parameters include displacement, stress, strain and inclination, etc., and the monitoring of the vibration parameters of the structure is lacking. The parameters can directly reflect the current safety status of the structure. Therefore, it is very important to monitor the vibration parameters of the structure. [0003] Chinese patent CN201820281740.0 discloses an integrated slope monitoring pile based on the Beidou satellite navigation system, which monitors the displacement parameters of the structure in real time by locating the movement of the antenna. This patent only uses the most basic spat...
