Re-connectable light-rail vehicle network system and network total system based on field bus

Abstract

The invention provides a re-connectable light-rail vehicle network system and network total system based on a field bus. The network system comprises a reconnection gateway, a vehicle control unit and multiple functional module units, wherein the reconnection gateway is connected with the reconnection gateways of other vehicle network systems through the field bus, and interacts the vehicle state information carried in a packet based on the field bus transport protocol; the vehicle control unit is used for sending a control instruction to each functional module unit of the vehicle, and sending control instructions to other vehicles through the reconnection gateway; and the functional module units are connected with the vehicle control unit and used for receiving the control instruction sent by the vehicle control unit. Through the re-connectable light-rail vehicle network system and network total system based on field bus provided by the invention, the defects of complicated wiring, many faults and the like caused by dependence of the prior art on hard wire control are overcome, reconnection operation of multiple vehicles is realized, and the passenger capacity of the vehicle is changed.

Description

technical field [0001] The invention relates to rail vehicle technology, in particular to a fieldbus-based reconnectable light rail vehicle network system and a total network system. Background technique [0002] With the rapid increase of the population of large and medium-sized cities at home and abroad, the problem of urban traffic congestion has increasingly become a stumbling block affecting economic development. Rail transit has been adopted by more and more cities because of its advantages of large passenger capacity, stable operation, punctuality, and no congestion. However, every city has the characteristics of tidal passenger flow to and from get off work, which makes some light rail vehicles overcrowded during peak hours and very few passengers during off-peak hours. Therefore, there is a requirement for light rail vehicles to flexibly change the number of train sets. When there are multiple train sets in each light rail vehicle, the problem of coordinated control...
