BRAKE DEVICE HEALTH DETERMINATION DEVICE AND BRAKE DEVICE HEALTH DETERMINATION METHOD

WIPO Patent Application WO/2023/074319

A1

The purpose of the present invention is to provide a brake device health determination device and a brake device health determination method that are capable of determining health of a brake in terms of pressure more accurately and alleviating inspection loads. A brake device health determination device (103) for determining health of a train in terms of air brake pressure comprises: a reference value calculation unit (101) that calculates an air brake pressure reference value (154) of the train by using information on a train operation command, a train occupancy rate, and a train regenerative braking force, and calculates a determination possibility signal (155) indicating whether or not health of the train in terms of air brake pressure can be determined; and a health determination unit (102) that determines health of the train in terms of air brake pressure according to the details of the determination possibility signal (155) by comparing an air brake pressure reference value (154) with a measured air brake pressure (156) of the train.
