Device and method for configuring address of vehicle bus equipment

Abstract

The embodiment of the invention discloses a device and a method for configuring an address of vehicle bus equipment. The device specifically comprises a signal collecting module, a control module, an equipment address storage module and an MVB (multi-vehicle bus) module. The device and the method have the advantages that by utilizing the mutual reaction of the four modules, the requirements of safe reliability, anti-jamming capability, conformance to dynamic network topology and the like can be simultaneously met; on the basis of the design idea and concept of separating the MVB equipment address and the specific module product, the free interchangeability among the similar types of equipment is met, the use complexity of the product is greatly reduced, the universality of the product is improved, the maintenance cost is reduced, and the maintenance time is saved.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a method and device for configuring addresses of vehicle bus equipment. Background technique [0002] With the rapid development of the rail transit industry and higher and higher application requirements, higher requirements are put forward for the safety and reliability of train network communication and system complexity; in order to better realize the requirements of train system integration, more and more The equipment and components of the train network communication system are connected to the train network communication system, and the network topology and equipment of the train network communication system change dynamically with different application occasions; therefore, the train network communication system facing this dynamic topology needs to find a reasonable The method of planning and configuring the device address of a single device in the system. For the device add...

Problems solved by technology

For the device address configuration of the equipment in the train network communication system, the traditional configuration methods can be summarized as: PCB single-board resistance configuration method, mechanical switch configuration method such as dial, and upper computer communication configuration method; among them, PCB single-board resistance configuration method The method has high safety and reliability and strong anti-interference ability, but this method cannot be applied to dynamic network topology; mechanical switch configuration methods such as dials solve the dynamic configuration problem, but the safety reliability, anti-interference ability, and product service life are greatly reduced. The upper computer communication configuration method uses the upper computer to communicate with the single-board processor for manual configuration, which can solve the problem of configuration flexibility to a certain extent on the basis of satisfying safety and reliability, but cannot realize arbitrary interchange between product modules (exchange requires Manual configuration), the configuration operation is complicated, which increases the product cost and configuration maintenance cost
