Train TCMS configuration management method based on software-defined network

Abstract

The invention provides a train TCMS configuration management method based on an SDN, and belongs to the technical field of train communication, and the method comprises the steps: receiving configuration information from a configuration computer; issuing a software defined network control instruction according to the configuration information; receiving response information fed back by the train terminal equipment after performing attribute configuration on the train terminal equipment according to the software defined network control instruction; confirming the received response information,and issuing a work starting instruction after confirming that the configuration information of all the equipment is consistent with the issued configuration information, so that the train terminal starts to work normally after receiving the work starting instruction, and the TCMS enters a formal operation state; periodically issuing a network state query instruction in the TCMS operation process;receiving own network state information responded by the train terminal equipment according to the network state query instruction; and performing network state evaluation according to the network state information. According to the invention, function configuration and equipment monitoring of each piece of equipment on the TCMS are realized through a unified control platform.

Description

technical field [0001] The invention relates to the technical field of train communication, in particular to a software-defined network-based train TCMS configuration management method. Background technique [0002] TCMS (Train Control and Management System, Train Control and Management System) is similar to the nervous system of the train, which realizes the control and monitoring functions of the train through the hardware equipment of the system and the software logic of the central control unit. [0003] At present, the Ethernet communication in the vehicle uses process data and message data communication conforming to the IEC61375-2-3 standard. The address of each on-board device adopts a preset static IP address, and each on-board device communicates according to a pre-designed communication protocol. The vehicle-mounted Ethernet switch performs port configuration (ring network configuration, interface attribute configuration, etc.) according to network design requirem...
