标准号: WO2021/073221(A1)

A train control DMI data redundancy control method. A DMI simultaneously receives and processes two groups of data which are mutually in a main and backup relationship, the DMI determines the main and backup relationship on the basis of a parsed result of the data, and the DMI displays main system data. The system comprises: two main control units used for separately sending data to the DMI, the two groups of data being mutually in a main and backup relationship;and the DMI used for simultaneously receiving and processing the two groups of data which are mutually in the main and backup relationship, determining the main and backup relationship on the basis of the parsed result of the data, and displaying the main system data. The DMI simultaneously receives the data sent by the two main control units, and respectively takes the two main control units as a main system and a backup system according to two main and backup system identifiers;when the main system is abnormal, the two main and backup system identifiers change, the main system and the backup system are switched after the DMI identifies that the two main and backup system identifiers change, the content displayed by the DMI is not affected, and a switching module does not need to be configured. The structure is simple, and the switching efficiency is high. The train control DMI data redundancy control system is further disclosed.

作者： WANG, Cheng 王成 LIU, Zhen 刘真 CHEN, Zhiqiang 陈志强 ZHANG, Guozhen 张国振 LIU, Jia 刘佳 LIANG, Jinning 梁进宁 LIU, Junfeng 刘浚锋

标准号: WO2020/258513(A1)

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.
