Real-time positioning analysis method and system for fuel gas pipeline network leakage source

Abstract

The invention discloses a real-time positioning analysis method and system for a fuel gas pipeline network leakage source, wherein the method comprising the following steps: a plurality of integrated detection modules are arranged in a region to be monitored, and the region to be monitored is divided into grid sub-areas; a hypothesis that each grid sub-area in the area to be monitored has a fictitious leakage source is carried out, another hypothesis of simulated detection data of the integrated detection modules is carried out after the fictitious leakage source continuously leaks for a preset time, and a simulated leakage database is established; the integrated detection modules acquire the practical measurement data of leaked gases in real time, and the practical measurement data is transmitted to a computer monitoring terminal; similarity calculation of the practical measurement data and a plurality of simulated detection data in the simulated leakage database is carried out, when the similarity reaches the maximal value, the position and time of the hypothesis leakage source and the continuous leakage time which are corresponding to the simulated detection data are the position and time of the practical leakage source and the time of the continuous leakage time. Through the adoption of the method and the system, the position of the practical leakage source can be quickly found out.

Description

technical field [0001] The invention belongs to the field of public security and the field of sensing technology, and in particular relates to a method and system for real-time location and analysis of gas pipeline network leakage sources. Background technique [0002] Gas is widely used in many aspects of urban operation, and the use ratio in all aspects is increasing day by day, which makes the role of gas in the lifeline of urban operation increasingly obvious. Once the pipeline ruptures, the leaked gas may cause fire, explosion and other accidents when exposed to open flames, causing serious harm to the lives of people around, buildings and the environment. The existing urban gas pipeline leakage location analysis technology basically uses the traditional drilling method or uses a gas alarm instrument to detect the air above the surface. The detection cycle is long and consumes a lot of manpower and material resources. In order to discover gas pipeline network leakage a...
