Train topology management method and system

Abstract

The invention provides a train topology management method and system, and the method comprises the steps: after a train is powered on, enabling a train topology manager in the train to judge whether the topological structure of each compartment node included in the train is changed or not: obtaining a train topology discovery protocol message sent by a gateway of the changed compartment node if the topological structure of one compartment node included in the train is changed, and updating the initial topology information table according to the field value contained in the train topology discovery protocol message to obtain an updated topology information table; and according to the updated topology information table, synchronously updating the topology information table stored in the compartment nodes except the changed compartment node in the train. Therefore, the unified management of the train communication network topology structure is realized under the condition that a program is not updated, the updating of the network topology information between compartment nodes can be dynamically completed, and the automation performance and effect of topology structure management of the train communication network are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train topology management method and a train topology management system. Background technique [0002] With the rapid development of the rail industry, in the era of big data, the functional requirements for the train communication network are becoming stronger and stronger, and the network topology structure will become more and more complex. Facing such a complex network topology, the demand for network topology management Also getting bigger and bigger. [0003] The existing network topology management method can realize the automatic marshalling function of trains and update the train network topology information through a certain train topology discovery protocol. For example, when a train joins, the topology information of the subsequently added train can be inserted into the original train network topology information, so as to update the train network topology inf...

Problems solved by technology

However, the above method can only realize automatic marshalling between trains, and cannot automatically update the original topology information when the topology structure in the train changes, making the train network topology information poor real-time performance, low reliability, and poor user experience
