Miniature comprehensive pipe gallery health monitoring system based on multi-physical field coupling analysis

Abstract

The invention provides a miniature comprehensive pipe gallery health monitoring system based on multi-physical field coupling analysis. The miniature comprehensive pipe gallery health monitoring system comprises a processing module, a conversion module, a transmission module and a sensor group, the sensor group comprises a water leakage sensor, a temperature sensor, a humidity sensor, a water pressure sensor, a water flow sensor and a gas sensor. The invention further provides a miniature comprehensive pipe gallery. The miniature comprehensive pipe gallery comprises a water supply pipe, a communication cable, a power cable and the miniature comprehensive pipe gallery. The invention further provides a monitoring method of the miniature comprehensive pipe gallery health monitoring system based on multi-physical field coupling analysis. On the basis of monitoring all index parameters in the pipe gallery in real time, associated monitoring indexes are analyzed more meticulously through multi-physical field coupling, and early warning is carried out on abnormal index parameters, so that targeted and effective monitoring is carried out on the miniature comprehensive pipe gallery, and theoperation safety and reliability of the miniature comprehensive pipe gallery are ensured.

Description

technical field [0001] The invention relates to the technical field of health monitoring for comprehensive utility corridors, in particular to a micro-comprehensive utility corridor health monitoring system based on multi-physics field coupling analysis. Background technique [0002] Compared with the large-scale integrated utility gallery, the micro-integrated utility gallery has a smaller cross-sectional area (2.0-3.0m in length and 1.0-2.0m in width), limited internal space, and many types of pipelines that are densely distributed (mainly including water supply pipes, power cables and Communication cables), the convenience of staff entering and exiting maintenance is slightly poor. The comprehensive pipe gallery is an underground closed space, which is not ventilated and humid, so there is a possibility of generating volatile gases, flammable gases, and toxic gases, and water supply pipes may leak and cause water accumulation; at the same time, when the power equipment in...

AI Technical Summary

Problems solved by technology

At present, there is no relevant existing technology for the health monitoring of the micro integrated pipe gallery; for the health monitoring of the integrated pipe gallery, due to the interaction between various physical fields (such as temperature field, electromagnetic field, flow field, etc.), However, the existing technologies are single-index monitoring of various monitoring indicators (such as temperature, water pressure, and toxic gases), and there is no multi-physics field coupling analysis between monitoring indicators.
