本文所介绍的是微型计算机在小型水电站中应用实例之一。从流程图可知充分运用了微型计算机宜作实时监测和实时控制的特点,执行元件每动作一步都要作出判别,屏幕显示其故障的性质和内容。从而,提高了开机速度,防止故障扩大。输出回路中执行元件采用无能点电路,电压较高;为防止零点漂移,保证微型计算机安全,输入输出回路均采用光电耦合,将不同电压等级的电路分开。本例以尽量使用原有操作机构为原则,便于推广使用和借鉴。

This article describes one of the applications of microcomputers in small hydropower plants. From the flow chart shows that make full use of the microcomputer should be suitable for real-time monitoring and real-time control of the characteristics of each step of the actuator to make a decision, the screen shows the nature and content of its failure. Thereby, the boot speed is increased to prevent the fault from expanding. Output circuit in the implementation of components using pointless circuit, the voltage is high; in order to prevent zero drift to ensure the safety of the microcomputer, the input and output circuits are used optocoupler, the different voltage levels of the circuit separate. In this case to maximize the use of the original operating mechanism for the principle of easy to promote the use and reference.
