System of utilizing light rays having angles therebetween to carry out displacement monitoring and measurement method thereof

Abstract

The present invention provides a system of utilizing light rays having angles therebetween to monitor displacement change. The system is characterized by comprising a light ray emitter, a light ray reception target, a data acquisition unit and a remote server, wherein the light ray emitter can emit three beams or multiple beams of light rays having angles therebetween, the light ray reception target is arranged at a monitoring point, and the light ray emitter is arranged at a stable position having a certain distance with the light ray reception target, so that the three beams or multiple beams of light rays having the angles therebetween and emitted by the light ray emitter can irradiate on the light ray reception target directly. The light ray emitter and the light ray reception target are connected with the data acquisition unit via a wireless local area network, the data acquisition unit transmits the displacement change condition to the remote server, and the remote server can store and analyze the data, and carries out the early warning on a monitoring value exceeding an engineering allowable value. The system and method of the present invention can realize the real-time monitoring and the early warning automation, enable the engineering safety to be improved and the personal error to be reduced, are high in monitoring precision and wide in monitoring range, and are convenient to popularize.

Description

technical field [0001] The invention relates to the fields of civil engineering, geological engineering and geological disaster monitoring, in particular to a system and method for monitoring displacement changes by using mutually angled light rays. technical background [0002] At present, in a large number of engineering practices in civil engineering, geological engineering, and disaster prevention and control, it is necessary to monitor the characteristics of displacement changes on the surface of rock and soil or engineering structures. For rock-soil masses or engineering structures with large deformation or accelerated deformation, real-time monitoring and early warning must be realized, so as to effectively prevent accidents and disasters. At the same time, it is also necessary to monitor the deformation state of the rock and soil mass or building structures that are being reinforced and processed in real time, so as to grasp the construction effect and ensure the saf...

Problems solved by technology

However, this method is complicated to operate and cannot eliminate manual errors; each measurement requires professionals to set up instruments and monitor, which is highly dependent on manual work and has a high return rate

[0004] For monitoring objects located in remote areas, traditional monitoring methods require monitoring personnel to repeatedly travel to and from monitoring locations, which increases transportation costs and cannot achieve automatic real-time monitoring

In addition, for more dangerous monitoring objects, such as landslides in the accelerated deformation stage, traditional monitoring methods are likely to cause safety hazards and threaten personal safety.
