Design Of Leakage Monitoring And Management System For Underground Gas Pipeline

Natural gas has been used in all aspects of social life because of its low pollution and environmental protection.The main way of natural gas transportation is pipeline,the monitoring and management of pipeline leakage is an important factor to ensure the safety of natural gas transportation.The undergroud gas pipeline is located in an complex environment,with low pressure,multi branch,multi Accessories etc.lead to leakage monitoring and management difficult,leakage monitoring of underground gas pipeline is one of the most pressing problem.The paper design and implement a real-time leakage monitoring and management system based concentration sensor network,the system uses the concentration sensor to collect the concentration of natural gas pipe network and send the data back to the control terminal for storage,analysis and alarm data processing,real-time monitoring and management functions to achieve the natural gas pipeline leak.The main contentsof the thesis include network topology model of the proposed sensor layout strategy and realizes the network layout,concentration sensor real-time collection and transmission of data,the design and implementation of the concentration control system.The control terminal system based on Access database for data storage,in the MyEclipse environment to develop the system for real-time analysis of the data collected in order to detect anomalies and to inform management of alarm based on real-time monitoring,to the leakage of natural gas pipeline network monitoring and management purposes.The system can complete the real-time monitoring and management of underground gas pipeline leakage,the system can meet the needs of the existing natural gas environment in terms of safety,practicality,functionality and cost.
