Abstract

PURPOSE: To discriminate a car causing trouble easily by a method wherein the number of counting in case of the ocurrence of trouble of the timer counter circuits of end processors loaded on each car is transmitted to a central processing unit together with trouble informations.
CONSTITUTION: End processors 2, 3 loaded on each car record the data of the electric apparatus of each car to memory circuits 22, 32 by means of interface circuits 23, 33, and fill up timer counters at the inside. When trouble is detected, count values in the memory circuits are kept in other memory regions with trouble contents, and these informations are transmitted to a central processor unit 1. The timer counters of each end processor are previously reset by means of the central processing unit simultaneously. When a plurality of end processors detect trouble, the central processing unit checks a point of time of the ocurrence of trouble on the basis of the values of each timer counter, conducts response with the counter having a smaller value, and collects data.
