Abstract

The invention discloses a method for determining a network message transmission route of a train vehicle. The method is applied on an ECN switch. A train grade communication network comprises at least two ETB switches. The method comprises steps of on the condition that at least two link fault points exist in the train grade communication network and the ECN switch is to transmit a first ring network message to the other ECN switch, determining a first transmission route according to the current network topology, and forwarding the first ring network message to the corresponding ETB switch through a corresponding network segment. The method and the device provided by an embodiment of the invention can eliminate or reduce an influence to integral vehicle operation on the condition that multiple link fault points exist, and furthermore improving availability of a train vehicle network. The invention further discloses a device for determining the network message transmission route of the train vehicle, wherein the device also has a corresponding technical effect.

Description

technical field [0001] The invention relates to the technical field of train vehicle networks, in particular to a method and device for determining a transmission route of train vehicle network messages. Background technique [0002] In the train vehicle network control and management system, the train-level communication network based on IEC61375-2-5 standard and the vehicle-level communication network based on IEC61375-3-4 standard are more and more widely used. The train-level communication network realizes communication routing and cross-marshalling communication, and the vehicle-level communication network realizes internal communication within the marshalling. [0003] At present, the train-level communication network includes an ETB (Ethernet Train Backbone, Ethernet Train Backbone Network) switch. The ETB bus adopts a linear topology. topology, such as figure 1 shown. [0004] The vehicle-level communication network adopts a ring topology, which can solve the impa...
