Title:
SYSTEM FOR COMMUNICATION BETWEEN GROUND AND TRAIN, ON-CAR DEVICE, GROUND DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP2016115996
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the reliability of radio communication between devices on the ground and on a train.SOLUTION: An on-car device identifies train control data 43 included in a communication frame 40 received from an IC tag using two modes together. Firstly, in a first mode, the on-car device does not perform whole verification for the whole of the communication frame 40 using whole verification information 47, but performs individual verification for the train control data 43 using individual verification information 44 included in the communication frame 40, and determines (adopts) the train control data 43 by multiple accordance determination. If the train control data 43 is not determined even if the processing is repeated while a prescribed grace period is satisfied, the on-car device shifts to a second mode. In the second mode, the on-car device performs the whole verification and individual verification of a communication frame 40 which was not a determination object in the first mode, and determines (adopts) the train control data 43 by multiple accordance determination.SELECTED DRAWING: Figure 2
