Intelligent urban gas PE pipe network measurement and control system and method

Abstract

The invention relates to an intelligent urban gas PE pipe network measurement and control system and method. The intelligent urban gas PE pipe network measurement and control system is characterized in that a plurality of measurement and control nodes are arranged on a pipe network between a gas source and a user; each measurement and control node can collect the pipe network gas running pressure, temperature and flow of the corresponding geographic position point of the PE pipe network and send the pipe network gas running pressure, temperature and flow to a master control room server through a wireless local area network and can also receive valve closing control instructions from the master control room server; and the position of each measurement and control node is provided with an intelligent PE valve, wherein the intelligent PE valve is provided with a power storage module, a pipe exterior master control module and a pipe interior wireless collection module. According to the intelligent urban gas PE pipe network measurement and control system and method, the intelligent PE valves are arranged on the pipe network in a segmented manner and are all connected to the master control room server of the urban gas PE pipe network through the wireless network, and through the monitoring analysis and leakage judgment method, real-time monitoring and safety monitoring of integral pipe network running are achieved.

Description

technical field [0001] The invention relates to an intelligent city gas PE pipe network measurement and control system and a measurement and control method. Background technique [0002] Under the background of rapid urbanization construction and energy saving and emission reduction work, the mileage of gas transmission and distribution pipeline network is also increasing rapidly, and more and more high-density PE pipes and valves are used in urban gas pipeline network. It has a series of characteristics such as corrosion resistance, long life and low flow resistance, and has a tendency to gradually replace the previous steel pipe network. However, with the rapid growth of the mileage of the urban gas pipeline network, the safety hazards of leakage and explosion also increase. Compared with the application of the existing safety monitoring technology for the operation of long-distance natural gas transmission trunk lines, the monitoring measures for the operation of the urb...

Problems solved by technology

This technical regulation method is suitable for routine inspections and leakage point search and location after manual pre-judgment of leakage reports. Obviously, the real-time performance is poor and time-consuming and labor-intensive.
