Design And Development Of Gas Pipeline WebGIS

The city gas pipeline is the equipment guarantee for safe gas transmission,is the energy base for urbanization,and is an important material guarantee for the normal life of urban residents.With the continuous advancement of urbanization,the number of gas users has increased rapidly,the demand for gas has risen sharply,and the construction of gas pipelines has been rapid.The gas pipelines are transformed from a simple,low-density distribution pattern to an intricate,high-density distribution pattern,and gas accidents occur from time to time.However,for these problems or phenomena,the traditional management model has such disadvantages as low information visualization,weak spatial analysis capabilities,untimely incident handling,and low work efficiency.Therefore,in order to solve the above-mentioned management situation,it is very necessary to build a flexible,stable,and fully functional gas pipeline management system.In view of the current situation in the construction of gas pipeline network systems,the C/S development model has the advantages of powerful and efficient data query,statistics,spatial analysis,and display,but the update and maintenance of the C/S mode system is quite tedious.There are also problems with sharing,and with the popularity of the Internet and the rapid development of Web technologies,people are accustomed to handling daily affairs through the network.Therefore,this article uses WebGIS as technical support,adopts B/S development model,and uses MySQL as the system database.Using the ArcGIS for Server platform to release pipe network data and geographic data,developed on the server side using Java Web technology,developed on the browser side using JavaScript and ArcGIS API for JavaScript,and built a gas pipeline system based on B/S mode.In terms of system functions,it includes functions such as query positioning,pipe network editing,and pipe network analysis.The system also integrates with mobile devices and SC AD A monitoring systems to provide location monitoring,track playback,and mileage statistics for inspectors.Provides SCADA analysis of key equipment in the pipeline.Position monitoring can obtain the current position of the inspector in real time,and the track playback can dynamically display the trajectory of the inspector.SCADA analysis monitors the operational status of key equipment in the pipeline,uploads it to the server and performs real-time monitoring on the client.It satisfies the functional requirements of gas pipeline processing and analysis,and at the same time,it effectively controls the occurrence of gas accidents,ensures the efficient and stable safe operation of the system,and effectively solves the practical problems faced in the management of urban gas pipelines.
