Natural gas pipeline real-time monitoring system based on Zigbee wireless communication technology

Abstract

The invention relates to a natural gas pipeline real-time monitoring system based on Zigbee wireless communication technology. The natural gas pipeline real-time monitoring system is characterized in that critical parameters of natural gas pipelines are acquired and transmitted in real time by the wireless communication, alarms are made for abnormalities of the critical parameters of the natural gas parameters, and abnormal points of the pipelines are effectively located. The monitoring system has the advantages of instantaneity, high automation degree and reliability and high information processing ability. Dangerous accidents are prevented to some extent. Once the natural gas pipelines have accidents of leakage, abnormal temperature and humidity, damage to construction and corrosion, the monitoring system can send alarms in time, changes of various parameters such as gas leak, temperature, humidity, vibration, corrosion and the like of the gas pipelines during accidents can be truly reflected, reliable and effective information can be provided for management personnel by taking necessary measures, so as to reduce damage and loss caused by dangerous gas leak and explosion, the defects of conventional natural gas pipeline detection are overcome, and the monitoring system has high application value.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and is a real-time monitoring system for natural gas pipelines based on ZigBee wireless communication technology, which is used for monitoring natural gas leakage, pipeline ambient temperature, construction damage and pipeline corrosion of natural gas pipelines. Background technique [0002] With my country's economic development and scientific and technological progress, the demand for natural gas is increasing day by day. At the same time, natural gas leakage incidents occur frequently, posing a serious threat to people's lives and properties. Therefore, the safe transportation of natural gas and the leak detection of pipelines have become key issues. By the end of 2011, my country's natural gas pipelines have been laid as long as 50,000 kilometers, and it is expected that my country's natural gas pipelines will reach 100,000 kilometers in 2015. Once such a huge pipeline network...
