Title:
TRAIN SECURITY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/158702
Kind Code:
A1
Abstract:
In train control with a moving block system, an on-board device requires a mechanism for monitoring the number of cars and train integrity and reporting them to a ground device. Further, information that is transmitted to the ground device is required to be highly reliable and secure. Therefore, this train security system has a first on-board security device mounted on a first car located at the head of the train, a second on-board security device mounted on a second car located at the rear end of the train, and a transmission line connecting the first on-board security device and the second on-board security device. A train integrity management unit provided in at least the first on-board security device monitors establishment or loss of train integrity of the train on the basis of the content or state of communication on the transmission line.
