Structure health monitoring system applied to cable and cable channel

Abstract

The invention relates to a structure health monitoring system applied to a cable and a cable channel. The system comprises a monitoring system, a diagnosis system and a state evaluation system, and is characterized in that the monitoring system comprises a sensor, a data acquisition module and a signal processing module; the diagnosis system comprises a modeling module, an identification module, a model updating module, a simulation computer module and a damage positioning assessment module; and the state evaluation system comprises a residual amount estimation module, a life expectation module, a reliability analysis module, a life period cost analysis module and a repair maintenance planning module. The structure health monitoring system provided by the invention is applied to management of monitoring data of dispersive and respective independent construction fields, can also carry out concentrated unified management and long-term storage on all the monitoring data, enables users to timely and accurately query and obtain monitoring information, can also provide a scientific basis for operation decision-making, construction and operation safety and reduction of the construction and maintenance cost, and provides good management experience for later similar engineering.

Description

technical field [0001] The invention relates to the field of electric power monitoring, in particular to a structural health monitoring system applied to cables and cable channels. Background technique [0002] At present, there is no complete solution for tunnel health monitoring at home and abroad, and the ongoing monitoring mostly adopts the method of manual regular monitoring. If the tunnel is always in operation, this monitoring method is often impossible to achieve due to the need to block traffic and other reasons. Moreover, data collection, processing, and report formation using traditional monitoring methods are performed manually, resulting in low efficiency and high error rates. The on-site monitoring data still stays in the file management mode, which leads to the inability to share the data, make it difficult to query, and reduce the work efficiency and management analysis level. Data display is not intuitive, information feedback is slow, and it is diffic...
