MONITORING EQUIPMENT FOR TRAIN

PURPOSE:To analyze trouble sufficiently by a minimum memory capacity by recording a fixed number of information collected at ever sampling time to a memory section as first recording information and a fixed number of information at every specified number as second recording information. CONSTITUTION:A processing section 2 updates and records the latest collecting information to a memory in succession as first recording information (a) for the time t1min at every sampling time. The processing section 2 updates and records it to the memory successively as second recording information (b) for the time t2min at every five sampling time. When an information signal changes at timing 11, the first recording information and the second recording information for the time t1 and t2min are not updated, and stored in the memory. The first recording information and the second recording information for the time t3 and t4min are not updated, but instead stored in the memory. Information stored in the memory is read, and an accident is analyzed.
