Pipeline Safety Monitoring and Early Warning Methods

Abstract

The invention provides a pipeline safety monitoring and early warning method. The method comprises the following steps that a pipeline multi-direction strain-stress model is constructed; a single-point ground settlement pipeline equivalent strain model is constructed; according to the pipeline multi-direction strain-stress model and the single-point ground settlement pipeline equivalent strain model, a single-point ground settlement pipeline comprehensive stress model is constructed; according to the single-point ground settlement pipeline comprehensive stress model, a single-point ground settlement pipeline safety monitoring and early warning model is constructed; and through the single-point ground settlement pipeline safety monitoring and early warning model, safety state monitoring andearly warning of a pipeline are performed. According to the pipeline safety monitoring and early warning method, the safety state of the pipeline can be monitored accurately in real time, moreover, the dangerous state is early warned in real time, and the whole process is simple in construction and low in hardware cost.

Description

technical field [0001] The invention relates to the technical field of gas pipeline monitoring, in particular to a pipeline safety monitoring and early warning method. Background technique [0002] The gas pipeline network is an important public infrastructure of the city and one of the lifelines of the city. Most of my country's urban gas pipelines have been used for 10 to 30 years, entering a stage of high incidence of pipeline accidents. Moreover, due to reasons such as urban municipal construction, vehicle rolling, geological subsidence, and soil corrosion, gas pipeline network pipelines are prone to leakage accidents. Once a leakage accident occurs, it will cause huge economic losses and casualties. How to effectively monitor the safety status of pipelines in key areas in real time and give early warning of dangerous conditions is the key to preventing urban pipeline accidents and the basis for formulating emergency response plans. [0003] There are many factors that...

Problems solved by technology

[0005] 1. The service life of pipelines in key monitoring areas is generally long, and there is no pre-embedding of sensors in the same ditch. If a large number of sensors are to be buried in the same ditch later, the construction volume will be large, and it will cause a certain degree of wear and tear on the pipeline, and the cost is high;

[0006] 2. The topological network structure of buried sensors is complex, the data return is difficult, and it is related to the specific location of the ground subsidence and the geological environment. The measured data has a large amount of invalid redundancy and the accuracy of the simulation data is low. Therefore, it is difficult to form a stable prediction model and Accurate Monitoring Methods
