Document Type and Number:
WIPO Patent Application WO/2022/077955
Kind Code:
A1
Abstract:
The train position determination apparatus in the present invention calculates train position information after power on according to whether a train moves, the movement direction, the movement distance and train position information before power off which are provided by an auxiliary apparatus, and the process of re-determining the train position after the train is powered on is omitted, so that the re-powered-on train position determination apparatus can quickly determine the train position, and report the determined train position information to a ground device by means of a vehicle-mounted device in a timely manner, thus the train can quickly receive information, such as driving permission, from the ground device, and the process of re-determining the train position after the train position determination apparatus is powered on is omitted, thereby allowing the train position determination apparatus to come into a normal operation mode in a timely manner, improving the operation efficiency; in addition, the train position determination apparatus performs a validity check on ground information according to the received ground information provided by the auxiliary apparatus, and executes a command contained in the ground information which has passed the validity check, such as a level conversion command and a wireless call command, thereby improving the operation security.
