液化天然气  (LNG)加气站自动控制系 统
Automatic control system of liquefied natural gas (LNG) filling station

    我公司研发的液化天然气  (LNG)加气站自动控制系 统是液化天然气  (LNG)加气站的重要组 成部分,具有自主的核心技术,在国家科技示范工程新疆乌鲁木齐迎宾路加气站和长沙加气站以及海南加气站等项目中都已成功应用,操作简便、功能完善、运行可靠。
 液化天然气  (LNG)加气站自动控制系 统以西门子S7-300 PLC及工控计算机为硬件核心,加上我公司自主研发的应用软件,实现了对液化天然气  (LNG)加气站工艺全过 程的监测和控制。
 Automatic control system of liquefied natural gas (LNG) filling station developed by our company is an important component of liquefied natural gas (LNG) station and we possess the independent core technology. It has been applied successfully at Yingbin Road station in Urumqi of Xinjiang which is the national science and technology demonstration projects and Hainan, Changsha stations and so on. This system has advantages as follows: easy to operate, reliable to run and functions that consumers need.
 Automatic control system of liquefied natural gas (LNG) station is made up of siemens S7-300 PLC,IPC and application software independently developed by our company, it realizes monitoring and control to the entire process of the liquefied natural gas (LNG) stations.
