Based on Internet technology and big data as the engine, smart energy closely couples the power system with natural gas network, heating network, mining system, water system, industry, transportation and construction system for comprehensive collection, processing, analysis and application. Thanks to the development of automation technology and information technology, automation system is more and more widely used in the field of energy and water affairs, which provides a reliable guarantee for these industries to develop efficiently, reduce consumption, work safely, reduce human labor intensity, and improve work efficiency and management level. In the field of energy and water system, in the automatic production, the unattended remote control of well stations and pipeline transportation determines that the communication transmission equipment should be used in the harsh environment; There are many stations, well stations, pipelines, storage and transportation equipment and branches, with large geographical span, and the whole production and manufacturing management system is huge, which means that the response rate of the communication system is fast, supporting different distance transmission and super networking ability; Energy and water conservancy are the foundation of people's livelihood in every country, and network equipment must be safe and stable.
