摘要
本电路用单片机AT89C2051检测“开机”和“关机”信号，用软件延迟时间，实现煤电钻安全供电。抗干扰措施采用光隔离电路和“看门狗”电路。
With the help of the single-chip computer AT89C2051, the circuit receives'on'and'off'signals. The postponing of time is realized by means of the softwar, and thus making possiblethe safety electric supply for the electric coal drill .The light separation circuit and the 'watchdog'circuit are applied to counter interference.
