SYSTEM FOR MANAGING RAILWAY VEHICLE INSTRUMENTS, METHOD FOR MANAGING RAILWAY VEHICLE INSTRUMENTS, ON-BOARD DEVICE FOR MANAGING RAILWAY VEHICLE INSTRUMENTS, AND GROUND DEVICE FOR MANAGING RAILWAY VEHICLE INSTRUMENTS

WIPO Patent Application WO/2018/142697

A1

The tracking of instrument information is made possible and an accurate history of instrument information is obtained even when an attachment position, which is the position where a railway vehicle instrument is attached, is changed. Instrument information, which indicates the actions and statuses of railway vehicle instruments attached to attachment positions of units, is collected. Serial numbers determined for the attachment positions are updated at timings at which the railway vehicle instruments attached to the attachment positions can be replaced. Provisional IDs that include positional information including unit numbers and in-unit positional information, and that also include serial numbers, are assigned to the instrument information. The collected instrument information is added to a stored instrument information group. The provisional IDs assigned to the collected instrument information are added to a provisional ID group. Combinations of new provisional IDs and old provisional IDs, which are included in the provisional ID group and which are respectively assigned to new instrument information and old instrument information indicating the actions and statuses of the same railway vehicle instruments, are estimated.
