摘要
介绍了RTU(Remote Teminal Unit)系统在中石化榆济天然气管道中的应用,远程控制天然气长输管道阀室干线截断阀门。并详细介绍了RTU系统及其系统结构。RTU系统以远程控制气液联动阀为控制对象,可通过下位机可将阀门前后压力和阀位状态通过以太网传输到上位机,并实现调控中心和站场远程监控和操作。
This paper introduces the application of RTU system in the Sinopec Yuling-Jinan natural gas pipeline, and remote control the trunk cut off valve. It describes the RTU system and system architecture. RTU system with remote control valve to control the gas- liquid interaction object, can through the next bit machine can pressure before and after the valve and valve position state transmitted to the PC via Ethernet, and to achieve control center and station remote monitoring and operation.
