摘　　要：本文通过对阴极保护参数测控系统的功能需求分析 ,结合硬件设备状况和工作环境要求 ,提出了较为详细的设计方案和实现方法。该系统利用串口通信和Modem通信建立多种设备的本地及远程连接 ,实现了电压、电流、电位等现场数据的实时采集和现场设备的实时监控 ,而中心计算机则通过远程连接对各现场进行状态监控和数据查询。This paper puts forward the blue print for the design and the carry-out method based on the analysis of the functional needs of the system of cathode protection parameter observation and control and the request of the combination of equipment status and working condition. This system makes use of COM port and modem communication to set up various local and long-distance connection, which realizes the real-time collection of the local data and the monitor and control of local equipment, while the data-query by the long-distance connection.
