Urban gas pipe network safety monitoring and early warning method and system based on settlement monitoring

Abstract

The invention provides an urban gas pipe network safety monitoring and early warning method and system based on settlement monitoring, and the method comprises the steps: synthesizing urban land subsidence historical data and urban gas pipe network distribution and historical fault data, and employing a multi-factor judgment model and a GIS spatial analysis technology to carry out the division ofkey regions of gas pipe network settlement; selecting a key position of the key area as a settlement monitoring point, installing pipeline operation parameter acquisition equipment, constructing an urban gas pipe network settlement key area monitoring network, and acquiring pipeline operation parameters of each settlement monitoring point in real time; transmitting the pipeline operation parameters and the pipeline attribute parameters to a background server in real time through wireless communication; receiving, storing and preprocessing pipeline operation parameters and pipeline attribute parameters in real time through a background server, determining the current safety risk level of each settlement monitoring point pipeline based on the pipeline operation parameters and the pipeline attribute parameters by utilizing a pipeline settlement damage prediction model, and predicting and alarming pipeline faults.

Description

technical field [0001] The invention relates to the technical field of gas pipeline network monitoring, in particular to a settlement monitoring-based urban gas pipeline network safety monitoring and early warning method and a settlement monitoring-based urban gas pipeline network safety monitoring and early warning system. Background technique [0002] Land subsidence is one of the important factors causing gas pipeline leakage. When the pipe support settles, the pipe stress changes, causing the pipe to deform. The degree of pipe deformation is also affected by the properties of the gas pipe itself, such as pipe material, service life, pipe diameter, internal pressure, and temperature. [0003] In the past, the safety management of the urban gas pipeline network was mostly a passive after-the-fact response, which would not only cause huge property losses and casualties due to accidents, and cost a lot of money for emergency repairs, but also cause adverse effects on the so...

Problems solved by technology

[0003] In the past, the safety management of the urban gas pipeline network was mostly a passive after-the-fact response, which not only caused huge property losses and casualties due to the accident, and cost a huge amount of money for emergency repairs, but also caused adverse effects on the society.

At present, there is no complete and accurate safety monitoring system and method suitable for accidents caused by geological subsidence of gas pipelines in urban areas. It is very helpful to build a set of urban gas pipeline network safety monitoring schemes for geological subsidence that are in line with my country's national conditions. To improve the safety management level of my country's urban gas pipeline network
