Abstract

The invention discloses a monitoring point arrangement method for underground space gas explosion risk prevention and control. An effective monitoring point laying strategy is constructed in combination with the total system risk value, the investment reasonability of monitoring point laying and the system risk control rate; the maximum benefit value can be obtained through optimization, fund investment can be saved, the maximum detection efficiency can be obtained, the gas pipeline leakage situation can be found in time, secondary disasters caused by gas leakage are avoided, and the method plays an important role in guaranteeing safe operation of urban gas. On the basis of a traditional risk calculation method, the sensor prediction effect is originally introduced into explosion risk calculation of the adjacent underground spaces, and all the adjacent underground spaces within the gas pipeline leakage influence range serve as a whole to calculate the total risk value of the system.

Description

technical field

[0001] The invention relates to the technical field of risk prevention, control and monitoring, in particular to a method for arranging monitoring points for the risk prevention and control of gas explosions in underground spaces. Background technique

[0002] With the rapid expansion of urban population and the gradual expansion of urban areas, the popularization of natural gas applications has brought about the rapid expansion of urban gas pipelines. Due to the intricate nature of the city's underground pipelines, once a gas pipeline leaks, it can easily spread to adjacent underground spaces such as rain pollution and electricity and cause a large-scale explosion.

[0003] At present, there are two methods of leak detection and monitoring of urban gas pipelines: SCADA monitoring system and manual regular inspection. The SCADA system monitors the pressure and flow of each node in real time, but it can only effectively monitor the sudden drop in pressure cau...
