Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] The present invention proposes a train braking force distribution method, which is essentially a train traction system function integration and realization method based on the Train Network Control and Management System (TCMS). Resource sharing between devices, combining functions such as train traction characteristic and braking characteristic control, traction force and electric brak...

Abstract

The invention provides a train braking force distribution method and system. The method comprises the steps of: determining a state of a traction control unit (TCU) of a train according to a train network control and management system (TCMS); if the TCU is in a fault state, distributing the total braking force of the train to a braking control unit BCU of the train based on the TCMS; and if the TCU is in a normal state, distributing the total braking force of the train to the BCU and the TCU based on the TCMS. The system executes the method. According to different operation conditions of the train, calculation and distribution of the total braking force of the train are realized based on train TCMS network control, so that better automatic driving and subsystem control of the train are realized, the transmission time delay is reduced, and the bus burden is relieved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train braking force distribution method and system. Background technique [0002] In the development process of urban rail transit technology such as subway train technology, on the one hand, the network communication capability of subway trains is becoming more and more powerful. TCMS network can realize the synchronization, coordination and reliable traction and braking control of the whole train, and realize the networking of all functional equipment of the whole train. Communication and resource sharing improve train maintenance capabilities and reduce maintenance intensity; on the other hand, the control and operation of train subsystems are becoming more and more simplified and integrated. Less, which means higher demands on the functional management of the train traction control system. [0003] At present, the traction control methods of urban rail vehicles mainly...
