Abstract

The present invention proposes a method and system for allocating network communication addresses of train cars, wherein the method includes: the gateway obtains the car number of the train car where it is located; Each node within is assigned a corresponding communication identifier. The method and system for allocating network communication addresses of train carriages proposed by the present invention reduces the cost of product production version management and after-sales maintenance costs, and avoids the loss of products caused by human error (such as mistakes in product production management or train assembly). The problem that does not correspond to the carriage.

Description

Technical field [0001] The present invention relates to the field of vehicle engineering, and in particular, to a distribution method and system of a train compartment network communication address. Background technique [0002] At present, the electrical appliances distributed in each car on the train are similar, but the head and the car tail are different, and some power systems and vehicle control systems, such as the gate control system, light control system, etc., due to each section The functions of the car implementation are the same, so it is not necessary to distinguish the compartment. These general systems are basically used in a set of software, that is, the same electrical appliances are using the same identification code in each car (Identity, referred to as ID ID )send data. [0003] For train networks based on the Controller Area Network, the CAN) bus, since the CAN bus characteristics are limited, two different network nodes are not allowed to transmit data usin...
