Abstract

The invention relates to a redundant design method for a multifunction vehicle bus (MVB) network system. The method is characterized in that an MVB redundancy loop type network and a fault detection protocol for MVBs (FDPM) are configured in the method; the MVB redundancy loop type network comprises an MVB primary equipment management node and slave equipment nodes, and the every two adjacent nodes are connected through two MVBs Line_A and Line_B; the FDPM comprises the MVB primary equipment management node and the slave equipment nodes, which are connected in series through links in sequence to form a FDPM looped network. The method is mainly applied to the MVB network communication system based on TCN (Train Communication Network) standards, can be used for reliably replacing the buses in real time according to the FDPM when the MVB redundant network system has a fault, has the characteristics of high design reliability, high practicality and good redundancy and fault tolerance performance, and is of great significance on reliability improvement of an MVB communication network.

Description

technical field [0001] The present invention relates to the MVB (Multifunction Vehicle Bus) network control system that conforms to the TCN (Train Communication Network) standard, specifically, relates to a multifunction vehicle bus MVB network system redundancy design method; It is of great significance and can be widely used in industrial control fields with high real-time requirements such as railway locomotives, EMUs, subway trains and urban rail transit vehicles. Background technique [0002] With the development of high-speed trains and automation, more and more trains use the train communication network TCN. The train communication network is a high-performance comprehensive control that integrates modern train control, status detection, fault diagnosis and passenger service information transmission. System, the multifunctional vehicle bus MVB is an important part of the system; the MVB bus is a standard communication medium for transmitting and exchanging data betwee...
