OPERATION INFORMATION OUTPUT METHOD OF EACH CAR APPARATUS IN CAR TRAIN

PROBLEM TO BE SOLVED: To output the operation information having much data volume to a car monitor without interfering with transmission of operation information of other apparatus.SOLUTION: The operation information output method includes outputting operation information of various apparatuses 2a to 2n installed in cars 1a to 1n to a car monitor 3 installed on a lead car 1a. The information having less volume of data for a shorter transmission time, therefor with no interference with transmission of the operation information of other apparatuses 2a to 2n even if it is transmitted on a steady basis, is transmitted to the car monitor 3 all the time. Meanwhile, such information that has much volume of data for longer transmission time, therefor interfering with transmission of the operation information of other apparatuses 2a to 2n in case it is transmitted at all times, is temporarily stored in the apparatuses 2a to 2n, and the information having much volume of data that has been stored is transmitted to the car monitor 3 only when a command is issued from the car monitor 3. Alternatively, a complex analysis is performed based on the information having much volume of data that has been stored, and then it is transmitted to the car monitor 3. Only by enhancing analyzing function by increasing a memory capacity of each apparatus with no additional facility, a detailed condition of cars can be obtained.
