介绍了一种可以完成输电线路的电流、电压、功率电度和频率等电量的实时采集和动态显示的变电站模拟屏电量采集系统。该系统采用16位单片机实现数据采集和控制，针对显示条数量大的特点，设计了紧凑合理的显示条及相应的译码电路。现场运行结果表明系统运行可靠，测量数据准确，显示直观清晰，值得大力推广应用。
A kind of analog screen charge collection system of substation that can realize real-time acquisition and dynamic display of electric current, voltage, power and frequency of transmission line is introduced. The system uses 16-bit single-chip microcomputer to achieve data acquisition and control, in view of the large number of display features, designed a compact and reasonable display of the corresponding decoding circuit. Field operation results show that the system is reliable, accurate measurement data, display intuitive and clear, it is worth to promote the application.
