摘　　要：为实现输油管道阴极保护系统的远程自动化监测与参数集中管理,开发了一种基于GPRS的分布式管道阴极保护参数远程监测系统;设计监测终端检测现场保护点的阴极电位、恒电位仪电压和阴极保护电流,采用GPRS无线网络以TCP/IP方式远传数据至监测中心工控机,实现了分布式多监测点阴极保护状态的在线监测与参数管理;运行测试结果表明,该系统稳定可靠,实现了对多站点、多通道数据的远程集中监测,阴极电位的检测精度达到了0.5%,可满足输油管线阴极保护的远程自动化监测需求。To realize the automatic remote monitoring and parameters centralized management of oil-- pipeline cathode protection sys- tem, a distributed pipeline cathode protection remote monitoring system based on GPRS is developed, in which the collection terminals are designed to detect the cathode potential, potentiostat voltage and cathode protection current parameters in each spot point, then the acquired data are transmitted to IPC of monitoring center by GPRS wireless network with TCP/IP mode. Finally, the online monitoring and parame ters management are implemented for distributed cathode protection state monitoring. The operation test results show that the system is sta- ble and reliable, which realizes remote centralized monitoring for multiple sites and multi--channel data, and the detection accuracy of cath- ode potential reaches 0. 5%, thus, the system can meets remote automation monitoring requirements of oil pipeline cathode protection.
