Patent No. EP3592625 (titled "System For Monitoring The Integrity Of A Train") was filed by Hitachi Rail GTS Austria on Feb 21, 2018. The application was issued on Jun 7, 2023.
A train integrity monitoring system that leverages existing onboard balise antenna units to determine train composition and detect decoupling events. The system identifies the first balise antenna unit based on the train's direction of travel, eliminating the need for additional devices or structural modifications. The existing balise antenna units are used to query the train's integrity, eliminating the need for complex testing and approval procedures.
