Problems solved by technology

[0003] In the prior art, the process data port address allocation in the MVB controller is fixed, that is, according to the agreement, the ports of various devices can be one or more of the 0-4095 ports, so the ports of different devices may be quite different, and may A certain device is set with ports 1-10, while another device is set with ports 3000-3020, so since the process data port address allocation is fixed, it i

Abstract

The invention provides a process data dynamic distribution MVB controller and a data processing method thereof, relating to the train control network system technology field. According to the controller and the method, through setting process data port address dynamic distribution space and process data configuration space in a communication storage module, one to one corresponding of each port and each address of the process data configuration space is carried out through the process data port address dynamic distribution space and the process data configuration space, and the port is configured according to corresponding relation. Through the controller and the method of the invention, process data full address global function code dynamic addressing can be realized with small process data space, 4096 ports full address addressing of process data can be realized with small storage space, the MVB controller can be flexibly configured as various MVB devices, design is reliable, upgrade is convenient, and flexible modification can be carried out according to different application occasions.

Description

technical field [0001] The present application relates to the technical field of train control network systems, in particular to a process data dynamic distribution MVB controller and a data processing method. Background technique [0002] TCN (Train Communication Network, Train Communication Network) is composed of MVB (Multifunctional Vehicle Bus, Multifunctional Vehicle Bus) and WTB (Twisted Train Bus, Twisted Train Bus), which are interconnected by gateways. MVB is the vehicle bus part of the train communication network TCN, which is used to realize the serial data communication between the standard equipments located in the same vehicle or in different fixedly connected vehicles with interoperability and interchangeability requirements. The MVB controller is the core processing unit on the MVB bus. It is independent of the physical layer and functional devices, and provides communication interfaces and communication services for each node device on the bus; it can reali...
