摘　　要：某天然气净化厂水源站原配套控制系统采用进口设备,在使用过程中存在故障率高,运行维护成本高和备件组织周期长等问题。为保证该厂供水系统的正常运行,该厂技术人员开发了基于PLC的控制程序及通信平台,精简了数据协议转换次数,且新系统成本低廉、通用性强、使用的硬件易采购。新系统全面解决了困扰水源站正常运行的各种问题。A set of imported equipment has been adopted in the supporting control system in a water source station in Changqing natural gas purification plant. During the running process, however some problems occurred, such as the high rate of breakdown, high cost of operating maintenance and long period of organizing spare parts, etc. In order to ensure a regular running process of the water supplying system, the professional technicians in the gas plant has explored a controlling program and a communicating platform, both are based on PLC, reducing the conversion frequency of data protocol. The new system costs lower, can be widely common used, its supporting hardware can be easily purchased. Besides, it solved all kinds of problems plaguing the normal process of the water source station.
