D-series high-speed train control system fusion architecture

Abstract

The invention provides a D-series high-speed train control system fusion architecture which comprises a plurality of Ethernet train backbone gateways and a plurality of Ethernet vehicle marshaling gateways connected with the Ethernet train backbone gateways, and the Ethernet vehicle marshaling gateways are connected in series. The types of the Ethernet vehicle marshaling gateways are divided into end vehicle gateways and middle vehicle gateways, the end vehicle gateways are arranged on front end vehicles and tail end vehicles, and the middle vehicle gateways are arranged on middle section vehicles; a fusion controller is arranged on each Ethernet vehicle marshalling gateway, and an LCU main board, a traction control main board and a brake control main board are integrated on each fusion controller. According to the architecture, the vehicle control functions are sorted, the functions are classified and divided, the vehicle control architecture is formed according to the execution device, the vehicle control and the train control, integration of original logic functions of a plurality of control units is achieved through centralized deployment of the functions in the vehicle control units, cross-system interaction delay is reduced, and control accuracy is improved.

Description

technical field [0001] The present application belongs to the technical field of rail transit equipment and complete vehicles, and in particular relates to a fusion architecture of a control system of an EMU. Background technique [0002] The current train vehicle design is based on the mature network control, traction, braking, doors, air conditioning and other subsystem products as the premise, and the complete vehicle design is completed from the bottom up through appropriate adjustment of the interface. In terms of configuration, each subsystem is distributed in different vehicles. Each end vehicle is equipped with at least one network central control unit (CCU), each vehicle is equipped with at least one brake control unit (BCU), and each motor vehicle is equipped with at least one Traction Control Unit (TCU). The control units of each subsystem operate independently of each other, and realize the functions of the entire EMU through the interconnection of the train net...
