Object deformation early warning monitoring system and method

Abstract

An object deformation early warning monitoring system and method are disclosed. The system comprises a plurality of light emitting and receiving nodes, a receiving controller, and a processing unit. The plurality of light emitting and receiving nodes and the receiving controller are successively arranged at an object monitoring point. Two paths of light are emitted from the first light emitting and receiving node to the next light emitting and receiving node. The first path of light is an encoded light beam after encoding and encryption. Starting from the second light emitting and receiving node, each light emitting and receiving node decodes and proofreads the received encoded light beam through a light decoding detection controller arranged on the node. After proofreading is successful,forwarding is performed and finally the light beam is transmitted to the receiving controller. The second path light is a continuous non-coding light beam, which is successively forwarded by the plurality of light emitting and receiving nodes, and finally is transmitted to the receiving controller. Displacement or deformation alarm is issued only when the first and second paths of light is not received by the receiving controller. In the invention, system false alarm is greatly reduced, the system and the method are not influenced by an external light interference, and long distance monitoringis realized.

AI Technical Summary

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
