Abstract

주(主)마이크로컴퓨터가 관리하는 부(副)마이크로컴퓨터의 동작이 조금이라도 이상이 있을 때에는, 주마이크로컴퓨터는 부마이크로컴퓨터와의 관계를 완전히 무시하여 주마이크로컴퓨터가 잘못 판단하지 않도록 한다. 주제어장치와 부제어장치를 구비하여, 주제어장치는 상기 부제어장치에 주기적으로 요구신호를 공급함과 아울러 부제어회로는 주제어회로에 적어도 각 회로부의 감시결과를 포함하는 응답신호를 반송하는 다중 통신통신장치에서, 주제어장치는 요구신호를 공급한 후에 부제어장치로부터 응답신호가 소정시간을 넘어도 반송되지 않을 때, 단선상태로 판단하여 부탑승자 보호장치의 직류전원으로의 급전을 정지시킴과 동시에 경보신호를 출력한다.If the operation of the secondary microcomputer managed by the primary microcomputer is a little abnormal, the primary microcomputer completely disregards the relationship with the secondary microcomputer so that the primary microcomputer does not judge wrongly. A main control device and a sub control device, wherein the main control device periodically supplies a request signal to the sub control device, and the sub control circuit carries a response signal including at least the monitoring result of each circuit section to the main control circuit. In the device, when the response signal is not returned even after a predetermined time from the sub-control device after supplying the request signal, the main controller judges that it is in a disconnected state and stops the feeding of the sub-rider protection device to the DC power and alarms at the same time. Output the signal.
