Network convergence-based train control and management system, communication method and communication device

Abstract

The invention relates to the technical field of rail transit trains and discloses a network convergence-based train control and management system. The system comprises an Ethernet component network; equipment of an automatic train control system is accessed to the Ethernet component network through an Ethernet interface; the equipment of the automatic train control system is directly communicatedwith the Ethernet component network; each brake control unit is connected to the Ethernet network through an Ethernet interface and directly communicates with the Ethernet component network; the brakecontrol units directly communicate with each other through the Ethernet. According to the system of the invention, vehicle-mounted network layout and interfaces among all systems are optimized, therefore, system complexity is reduced, integrated train control logic integration and optimization design can be realized from the perspective of the whole system of a rail train, the performance and reliability of the train can be improved, and the train can be managed, controlled and maintained based on a unified platform. The invention further discloses a communication method and communication device of the network convergence-based train control and management system.

Description

technical field [0001] The present application relates to the technical field of rail transit trains, in particular to a network-integrated train control and management system, a communication method and a communication device. Background technique [0002] The traditional rail train network system is usually composed of multiple sets of network systems serving different purposes. Each system in the rail train generally has its own independent network, such as the signal network serving the train control function and serving the train control and management. Train Control and Management System (TCMS for short), serving the Controller Area Network (CAN for short) of the on-board braking system, and serving the Passenger Information System (PIS for short) Ethernet, CAN serving the door control system, etc. With the continuous development and maturity of Ethernet technology, Ethernet has been rapidly promoted and developed in the field of rail trains by virtue of its openness ...

AI Technical Summary

Problems solved by technology

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related technologies: the integration between the rail train control network and the information service network is only the sharing of physical media, such as the sharing of equipment or cables, the rail train The internal information of the control network and the information service network are still independent of each other, and it is necessary to provide a solution to make the rail train network more integrated
