A dynamic network configuration system and method based on mvb bus

Abstract

The invention discloses a dynamic network configuration system and method based on MVB bus. The dynamic network configuration system based on the MVB bus includes a bus, a plurality of bus devices, and the bus and the bus devices are connected by a network configuration interface device arranged on the bus device; the bus includes two groups of communication signal lines, power lines, grounding line, addressing line LINEA / B, and device identification line MatchRes_DetectA / B; the network configuration interface device includes a device identification module, a matching resistor connection module, and an addressing line state collection and transmission module. The present invention does not need to add additional hardware devices for address configuration, does not need to use subsystems or other devices, and other software for device address configuration, and can automatically complete the dynamic configuration of network addresses flexibly, reliably, and without manual intervention, thereby realizing dynamic Network configuration has important promotion value.

Description

technical field [0001] The invention relates to the field of rail transit, and more specifically, to a dynamic network configuration system and method based on an MVB bus. Background technique [0002] The rail transit vehicle control system has developed from a single centralized control and pure hardware circuit wiring form to a distributed network control of the entire train. Network control has become one of the necessary technologies for rail transit vehicles. At present, rail transit vehicles generally use a vehicle-level communication network based on the MVB bus that follows the IEC61375 standard to connect various subsystems in the vehicle. These subsystem devices only form the MVB ring network inside the vehicle level, and the communication bus connecting different vehicles generally uses the WTB network. [0003] MVB equipment can be divided into 6 types of 0 to 5 according to performance, of which 0 equipment does not have communication capabilities, 1 equipment...

Problems solved by technology

In the above three cases, in addition to the automatically configured open trains, the MVB bus can be used as the train bus to connect multiple different vehicles. At this time, the MVB bus connection between the vehicles is required to be flexible and convenient; The MVB network uses a fixed addressing method. When multiple vehicles are connected, it is necessary to determine the address settings of each vehicle one by one to avoid address conflicts. The operation is cumbersome, and it needs to be re-determined every time the connection is regrouped. It is easy to make mistakes in field use. , the efficiency is not high
