Intelligent pressure control method for city gas pipeline with gas operation based on Beidou positioning

Abstract

The invention discloses an intelligent pressure controlling method of an urban gas pipeline gasification operation based on Beidou positioning. The method comprises the following steps: 1, determining a position of a gas pipeline leakage point by utilizing a Beidou positioning system and a gas pipeline network database, and using the gas pipeline leakage point as a gasification operation point; 2, initially adjusting the flow and the pressure of a flow control point positioned at the upstream of the gasification operation point according to data feedback of the gasification operation point; 3, renewedly adjusting the flow and the pressure of the flow control point positioned at the upstream of the gasification operation point according to point pressure data, peripheral gas pipeline network data and gasification operation historical data acquired by detecting the downstream of the gasification operation point. According to the intelligent pressure controlling method disclosed by the invention, by intelligently adjusting the pressure in the pipeline, the aim of manual operation can be reduced, the difficult of low precision of pressure intensity control of the conventional gas pipeline gasification operation and poor security of the gasification operation can be solved, and first-aid repair targets of security, high efficiency, reasonability and completion are realized.

Description

technical field [0001] The invention relates to the technical field of urban gas pipeline equipment control, and more specifically, the invention is an intelligent pressure control method for urban gas pipeline gas operation based on Beidou positioning. Background technique [0002] In recent years, with the continuous expansion of urban scale and the increasing degree of modernization, urban buried pipeline networks have become more and more dense, especially pipeline construction projects for transporting natural gas, refined oil and other dangerous chemicals such as liquid ammonia and propylene. More and more problems such as pipeline corrosion and aging are gradually exposed, and pipeline leakage accidents occur from time to time. Among them, natural gas has become an indispensable part of the life of urban residents. It is also a flammable, explosive and harmful gas to human health. Once leaked, it will directly endanger the safety of people's lives and property. [00...
