Malfunction detection device of maikurokonpiyuta

摘要

(57) Abstract Objective Run cycle of program above fixed periodTo detect this even the abnormal generation time when it does not become, the microphone locoImplementing the malfunction detection device which can reset npiyuta securelyIt does. Constitution As for input signal S₀ entry interface 1, AThrough, D converter 2 it is supplied to micro-computer 3. MyAs for kon 3 the signal S _{A which} administers specified treatment the DA converterThrough 4, it supplies to differential amplifier 6. As for input signal S₀ entranceThrough power interface 1, the joint interface timeIt is supplied by also path 5, is equal to micro-computer 3 the treatment which administeringru. As for the signal S _{B where} treatment is administered with differential amplifier 6 the signalThe difference of S _A is calculated. This difference above specified value fieldConjunction, as for the abnormal judgment circuit 7 it judges as abnormality generation in micro-computer 3,The te, micro-computer 3 is reset.
