Abstract

본 발명은 두 개의 마이콤을 구비하고 있는 시스템에서 두 마이콤의 동작에 에러가 발생하는 지를 검출하는 것이다.The present invention detects whether an error occurs in the operation of two microcomputers in a system having two microcomputers.

본 발명은 두 개의 마이콤의 동작에 에러가 발생하는 지를 판별하고, 에러의 발생시 이를 검출하는 것으로서 펄스 검출부(10)가 두 개의 마이콤이 각기 출력하는 펄스신호를 출력하는 지를 검출하고, 펄스신호 검출부(10)의 출력신호에 따라 판단신호 출력부(20)가 전원을 충전 및 방전하면서 두 펄스신호 출력의 판단신호를 출력하며, 판단신호 출력부(20)의 출력신호를 비교부(30)미리 설정된 기준전압과 비교하여 에러 검출신호를 출력한다.The present invention is to determine whether an error occurs in the operation of the two micom, and when the error occurs, the pulse detection unit 10 detects whether to output the pulse signal respectively output by the two micom, and the pulse signal detection unit ( According to the output signal of 10), the determination signal output unit 20 outputs a determination signal of two pulse signal outputs while charging and discharging power, and the output signal of the determination signal output unit 20 is pre-set by the comparison unit 30. The error detection signal is output in comparison with the reference voltage.
