Object deformation early warning monitoring system and method

Abstract

An object deformation early warning monitoring system and method, the system includes a plurality of light emitting and receiving nodes, a receiving controller and a processing unit, and a plurality of light emitting and receiving nodes and receiving controllers are sequentially arranged at object monitoring points; from the first light The transmitting and receiving node sends out two paths of light to the next optical transmitting and receiving node; The optical decoding detection controller on the board performs decoding and proofreading after receiving the coded beam, forwards it when the proofreading is successful, and finally transmits it to the receiving controller. Finally, it is transmitted to the receiving controller; only when the first and second light are not received by the receiving controller, a displacement or deformation alarm is issued. The invention greatly reduces system false alarms, is not affected by external light interference, and realizes long-distance monitoring.

Problems solved by technology

[0003] However, the monitoring and early warning system in the prior art uses a single laser beam, which is not only susceptible to interference from external light, but also easily causes system false alarms due to abnormalities such as equipment damage and animals blocking laser signals, and increases manual workload.

In addition, due to the transmission of laser light by reflection, the attenuation of the laser beam is large, resulting in a short optical transmission distance of the system, which cannot realize remote and wide-range monitoring
