Abstract

The invention discloses a fuel gas pipeline leakage positioning and detecting method. A fuel gas meter sends a fuel gas flow passing through each family in a pipeline to a controller; a fuel gas sensor sends concentration information of a fuel gas outside the pipeline to the controller; the controller sends information detected by the fuel gas meter and the fuel gas sensor to an analysis module and a database; the analysis module is used for analyzing information detected by the fuel gas meter and the fuel gas sensor; and if the abnormality is found, the information is sent to the controller,and the controller sends the information to a terminal through a wireless emitter. The system can directly sends the abnormal position to the terminal, so that monitoring can be carried out conveniently and effectively, and the occurrence of accidents is prevented.

Description

technical field [0001] The invention relates to the field of gas, in particular to a gas pipeline leakage location and detection method. Background technique [0002] With the development of society, gas fuels such as natural gas and liquefied petroleum gas have gradually replaced traditional solid fuels such as wood and coal. Mass welcome. However, although gas has many advantages, it also has relatively high risks. While gas provides convenience to millions of households, it also causes many accidents. Therefore, real-time dynamic monitoring of gas is particularly important. Contents of the invention [0003] The technical problem to be solved by the present invention is that the efficiency of positioning and detection of existing gas pipelines is relatively poor, the use efficiency is low, and it is not convenient for long-term use. question. [0004] The present invention realizes through following technical scheme: [0005] A method for locating and detecting gas...
