Train information management apparatus, train information management system, and train information management method

A train information management system, comprising:

• a train information management apparatus to calculate a travel position of a train;
• and
• a ground apparatus to manage operation of the train,
• the train information management apparatus, including:
• a calculator to calculate a first travel position of the train based on the number of revolutions of wheels of the train;
• a beacon information receiving circuitry to receive information from a beacon;
• an on-board communication circuitry to communicate with a base station installed on ground and acquire identification information on the base station;
• a storage circuitry to store, when the train passes over a specific beacon that is the beacon specified, combined information of information on the specific beacon passed over, the identification information on the base station with which the on-board communication circuitry communicates, and information on a second travel position of the train;
• and
• a correction control circuitry to correct the first travel position with the second travel position using the combined information when the train passes over the specific beacon during operation in which the train does not stop at stations at a specified frequency and cannot reset the travel distance, and perform control to transmit the corrected first travel position to the ground apparatus via the on-board communication circuitry,
• the ground apparatus, including:
• a ground communication circuitry to communicate with the train information management apparatus via the base station and acquire information on the corrected first travel position;
• and
• a display circuitry to display the corrected first travel position.

A train information management method for a train information management apparatus, the method comprising:

• calculating, by a calculator, a first travel position of a train based on the number of revolutions of wheels of the train;
• receiving, by a beacon information receiving circuitry, information from a beacon;
• communicating, by an on-board communication circuitry, with a base station installed on ground and acquiring, by the on-board communication circuitry, identification information on the base station;
• and
• storing, by a correction control circuitry, when the train passes over a specific beacon that is the beacon specified, combined information of information on the specific beacon passed over, the identification information on the base station with which the on-board communication circuitry communicates, and information on a second travel position of the train in a storage circuitry, and correcting, by the correction control circuitry, the first travel position with the second travel position using the combined information when the train passes over the specific beacon during operation in which the train does not stop at stations at a specified frequency and cannot reset the travel distance.
