Device address reconfiguration method based on MVB communication

Abstract

The invention discloses a device address reconfiguration method based on MVB communication. The device address reconfiguration method comprises the following steps: S1, a TCMS sends an ''address reconfiguration'' signal to a VCMe-D of each vehicle in a train; S2, the VCMe-D receives the ''address reconfiguration'' signal and makes a vehicle MVB network switched out from a train backbone network, and the VCMe-D enters a master device working mode; S3, the VCMe-D sends address reconfiguration information to each device in the network to complete address reconfiguration of each device in the vehicle MVB network; S4, the VCMe-D switches the network state to the train backbone network and resumes a slave device working mode; and S5, the TCMS judges whether all devices are normal and terminates the address configuration process. By adopting the device address reconfiguration method disclosed by the invention, no manual operation is needed in the address configuration process, therefore an address setting error caused by human errors is avoided, and the address reconfiguration is efficient, flexible, convenient and good in reliability.

Description

technical field [0001] The invention relates to a network address reconfiguration method, in particular to a device address reconfiguration method based on MVB communication. Background technique [0002] With the continuous development of urban rail transit construction, urban rail transit trains have developed from the previous pure hardware circuit wiring form to a control mode based on hardware to build a train control and diagnosis system for vehicle information interaction management. Following the IEC61375 standard, the train network control and diagnosis system TCMS based on the MVB bus. On the previous trains, there were few equipment connected to the TCMS subsystem, mainly the key equipment on the train, such as traction system, braking system, signaling system, etc. These subsystem devices can only form an internal ring network at the vehicle level, and cannot realize MVB access of equipment at the train level ring network. [0003] Some subsystem device address...

Problems solved by technology

At the same time, these devices can only be installed on a fixed car and cannot be replaced at will. If you want to replace or exchange the device, you need to update the software or change the hardware to reconfigure the address.

Moreover, manual device address configuration may cause configuration errors, which will cause the device to fail to connect to TCMS normally. In this case, it is necessary to recheck the device address for configuration.

[0004] With the continuous development of train technology, more and more equipment and subsystems need to be connected to TCMS. Using the traditional address configuration method will not only greatly increase the workload of engineers, but also unavoidable possible configuration due to manual operation. wrong, unreliable
