Title:
CONTROL METHOD AND SYSTEM FOR DETECTING BRAKING FORCE OF TRAIN
Document Type and Number:
WIPO Patent Application WO/2020/258513
Kind Code:
A1
Abstract:
The invention belongs to the technical field of train operation protection, and discloses a control method and system for detecting braking force of a train. The control method comprises: measuring in real time and determining the actual deceleration of a train with two or more groups of accelerometers; judging whether the actual braking force satisfies the braking requirement according to the actual deceleration; determining that the actual braking force of the train is insufficient and taking emergency protective measures. The method uses accelerometers to directly measure the actual deceleration of a train, and has the characteristics of simple structure, easy implementation and small error. The method combines the monitoring of actual braking force with the speed protection, strengthening the functions of an automatic train control system and effectively guaranteeing the safety of train operation.
