In order to monitor and control equipments of the urban sewage pumping station real-time and remotely, this paper analyzes the features and realization method of SNMP protocol and OLE for Process Control(OPC) technology, and constructs an extended manager/Agent system by combining the two technologies, adopting'AgentX protocol and embedding OPC client into SNMP Agent. It verifies this method feasibly by examples and this new system can enhance the safe operation of equipment and improve the operating efficiency of the pumping station.%为实现对城市污水泵站设备的远程实时监测与控制,分析简单网络管理协议(SNMP)和OLE for Process Control(OPC)技术的特点及其实现方法.结合2种技术,运用AgentX协议及在SNMPAgent中嵌入OPC客户端的方式构建扩展代理/管理系统,通过举例分析,验证SNMP和OPC技术可增强设备的运行安全,提高泵站运行效率.
