Municipal pipe network health degree online monitoring system based on Internet of Things technology

Abstract

The invention discloses a municipal pipe network health degree online monitoring system based on the Internet of Things technology, which is characterized in that distributed fiber grating sensors areannularly distributed on the outer wall of a municipal drainage pipe network and used for measuring temperature data of the outer wall of a municipal sewage pipeline; a municipal pipe network adoptsa subsection control strategy, a control area is divided every 400-800 meters, and temperature data detected by distributed fiber grating sensors in each control area is sent to a monitoring center byan area switch through an optical fiber ring network; the monitoring center judges the leakage condition of the municipal drainage pipe network according to temperature data detected by the distributed fiber grating sensors. The system can overcome many defects and limitations of a traditional manual detection mode and a traditional sensor, and has the advantages of accuracy, stability, high efficiency, high reliability, easiness in networking, timeliness and long-term performance.

Description

technical field [0001] The invention relates to the field of monitoring related to liquid leakage and pipeline deformation in a municipal pipe network, and is an online monitoring system for the health of a municipal pipe network based on Internet of Things technology. Background technique [0002] With the rapid development of my country's economy, especially the acceleration of urbanization, the scope of maintenance and management of the existing municipal pipe network is getting larger and larger, and the requirements for the monitoring of the municipal pipe network are getting higher and higher. Although the maintenance and repair measures for the old pipe network in my country have been gradually promoted in recent years, there are still some weak links, especially after the heavy rain in a short period of time, there will still be serious problems such as bursting and bursting of some municipal pipes. phenomenon of disaster. How to monitor the municipal pipeline networ...

AI Technical Summary

Problems solved by technology

[0003] Traditionally, manual monitoring is mostly used for the monitoring of municipal pipe networks, and most of the methods are regular or irregular monitoring. This method is not only inefficient, but also difficult to meet the requirements

As far as the existing monitoring methods are concerned, the monitoring of the health of the municipal pipe network cannot respond in real time, and it is often discovered that serious damage occurs

The traditional method cannot understand the status of pipeline leakage in real time, which has caused serious disasters such as municipal drainage pipeline bursting and even bursting, which does not meet the requirements of modern scientific management
