| Abstract: | 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. |
