Abstract

The invention discloses a real-time monitoring system for urban pipeline network leakage, which comprises at least one laser methane sensor and an analyzer, wherein the laser methane sensors are used for acquiring concentration values of methane within the range of a methane pipeline area in real time and acquiring position information of the pipeline area with the currently acquired concentration values of the methane, and the analyzer is used for receiving the concentration values of the methane transmitted by the laser methane sensors, receiving the position information of the pipeline area with the acquired concentration values of the methane, analyzing the concentration values of the methane according to preset analysis rules, and determining the position of the pipeline area with methane leakage within the range of the methane pipeline area. The invention further discloses a real-time monitoring method for urban pipeline network leakage, which includes the steps: acquiring the concentration values of the methane within the range of the methane pipeline area in real time; positioning acquisition points; performing analysis and calculation according to the preset analysis rules by the aid of the real-time acquired multi-point concentration values of the methane and the corresponding acquisition positions; and positioning the pipeline area with methane leakage. The leakage position can be accurately and rapidly positioned by the method.

Description

technical field [0001] The invention relates to the field of urban pipe networks, in particular to a method for real-time monitoring of urban pipe network leakage. Background technique [0002] The urban pipeline network, that is, the urban pipeline network system, includes various intricate pipelines laid underground in the city for the transmission of gas sources, water, electricity, etc. [0003] At present, the main sources of gas supplied by pipelines are natural gas and coal gas. This method of gas supply equipment usually consists of pipelines, gate stations, high-pressure stations, pressure regulating devices and auxiliary equipment on pipelines to form a pipeline network system. Since the pipeline is a concealed project, the pipeline equipment is aging and corroded seriously as time goes by. With the needs of urban construction, the gas pipeline network in many cities has changed the location of some pipelines, and the road widening and other reasons have caused t...
