System for managing railway vehicle instrument, and on-board apparatus for managing railway vehicle instrument

An on-board apparatus for managing a railway vehicle instrument, the on-board apparatus comprising:

• a computer coupled to a train, the computer configured to:
• collect instrument information indicating an operation or a state of each railway vehicle instrument respectively mounted to each mounting position that is each of at least one mounting position included in a composition of the train;
• update a to-be-updated identifier determined for each mounting position, and assign, to the instrument information, a temporary identifier including position information specifying each mounting position and the to-be-updated identifier;
• and transmit the instrument information and the temporary identifier to a ground apparatus physically separate from the train, the ground apparatus estimates a combination of temporary identifiers included in a temporary identifier group, the temporary identifiers being previously assigned, in a database, to pieces of instrument information indicating the operation or the state of the railway vehicle instrument, wherein the railway vehicle instrument is not a generic computer, wherein the composition of the train includes a vehicle having each mounting position, the railway vehicle instrument mounted to a mounting position holds a setting value even in a case where off/on of power of the vehicle is performed, the computer is configured to:
• (1) read a pre-start setting value to be taken by the setting value, from the railway vehicle instrument mounted to the mounting position when maintenance is started, write a start-time setting value unique to the mounting position tothe railway vehicle instrument mounted to the mounting position after reading the pre-start setting value, and cause the setting value to take the start-time setting value, and to (2) read an end-time setting value to be taken by the setting value, from the railway vehicle instrument mounted tothe mounting position when the maintenance is ended, write the pre-start setting value to the railway vehicle instrument mounted to the mounting position after reading the end-time setting value, and cause the setting value to take the pre-start setting value.

An on-board apparatus for managing a railway vehicle instrument, the on-board apparatus comprising:

• a computer coupled to a train, the computer configured to:
• collect instrument information indicating an operation or a state of each railway vehicle instrument respectively mounted to each mounting position that is each of at least one mounting position included in a composition of the train;
• determine necessary information required for setting, to the instrument information, a temporary identifier including position information specifying each mounting position and a to-be-updated identifier, the to-be-updated identifier being determined for each mounting position, and being updated;
• and transmit the instrument information and the necessary information to a ground apparatus, physically separate from the train, that (1) assigns the temporary identifier to the instrument information by using the necessary information, and (2) estimates a combination of temporary identifiers included in a temporary identifier group, the temporary identifiers being previously assigned, in a database, to instrument information indicating the operation or the state of the railway vehicle instrument, wherein the railway vehicle instrument is not a generic computer, wherein the composition of the train includes a vehicle having each mounting position, railway vehicle instrument mounted to a mounting position holds a setting value even in a case where off/on of power of the vehicle is performed, the computer is configured to:
