Abstract: In order to improve the safety and reliability of oil/gas remote transmission, the paper presents and designs a remote supervision and control system of valve based on PLC. The system consists of one monitoring main station and some valve substation, which are connected by radio station. The special characteristics of the monitoring system are the introduction of PLC to field data collecting and equipment controlling. The system structure configuration of hardware and the design of software are described in detail. The practice proves that the system has characteristics such as friendly interface, highly reliable, operation easily, safe and steady, and work well etc.
