Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with an embodiment of a gas pipeline network accident warning system.

[0036] This embodiment utilizes GIS technology to establish an early warning system for gas pipeline network accidents. GIS technology connects the gas pipeline network information with the corresponding geographical location, and creates a map and data interconnection. At present, most of the computer drawing software commonly used in my country's surveying and mapping industry is based on AUTOCAD software as the basic platform, and is secondary developed through AUTOLISP language or AUTOCAD VBA technology, so as to achieve the purpose of drawing pipe network diagrams, and most of the surveying and mapping data are used AUTOCAD database format for database building. The invention can directly convert the gas pipe network diagram drawn by the AUTOCAD software to GIS, so as to establish a visual management platform based on GIS te...

Abstract

The present invention belongs to the field of an automatic monitoring technology for city gas network, which relates to a warning method for gas network accident. The present invention comprises steps as follows: a gas network geographic information system is established; a gas network diagram which is drawn is read; a gas network attributing data and a spatial geographical data are read; the maximum allowable working pressure and the residual life time for the pipeline, including fault, are predicted by adopting the methods based on an invalid evaluation drawing and an artificial neural network; the real-time collection and automatic monitoring system of the gas network data is established; dynamic data, including the pressure of all pipeline nodes are collected real-timely; a dynamic or static alarming mechanism which real-timely monitors whether the pipeline in service leaks, operating pressure and service life is established. The gas network accident warning method provided by the present invention can effectively prevent serious gas accidents.

Description

technical field [0001] The invention belongs to the field of pipeline network operation monitoring, in particular to a GIS-based gas pipeline network automatic early warning technology. Background technique [0002] With the rapid development of the world economy, the rapid increase of population, the continuous growth of energy consumption, the surge of greenhouse gas and various harmful substances emissions, the human living environment has been greatly challenged. In this situation, natural gas, a clean and efficient energy source, is getting more and more attention, and the development of natural gas industry has become the best choice for countries all over the world to improve the environment and promote sustainable economic development. [0003] The "Tenth Five-Year Plan" clearly stated that with the support of national policies, urban gas should be actively developed for the purpose of improving the quality of life of residents, improving the atmospheric environment,...
