A kind of mvb dynamic configuration method and device

Abstract

The invention discloses a method and a device for dynamically configuring an MVB. The method comprises the steps of: 1) forming a network configuration file based on network data; 2) obtaining the network configuration file, and storing the configuration information into a first-level cache in the classified manner; 3) obtaining various configuration information from the first-level cache, and respectively storing the sequence of the configuration information desired for the MVB protocol in a second-level cache; 4) sequentially obtaining various configuration information for the MVB configuration from the second-level cache; When the configuration information needs to be modified, the corresponding configuration information is obtained from the first-level cache and then is modified. After that, the process is returned to the step 3) to re-configure the MVB till the configuration is ended. The device comprises a network configuration file forming module, a first-level cache configuration module, a second-level cache configuration module and a dynamic configuration module. According to the technical scheme of the invention, the advantages of simple implementation method, high configuration efficiency, high reliability, convenient maintenance and expansion, and the like are realized. Meanwhile, the restarting of the MVB protocol is avoided during the reconfiguration process.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for dynamically configuring an MVB (Multifunction Vehicle Bus, twisted train bus). Background technique [0002] The fast and correct configuration of MVB communication is the key factor to improve the versatility of MVB and reduce the development cost. The configuration of MVB protocol is mainly to save the configuration of MVB components in the memory in a certain format, and read the configuration when the program starts Parameters to configure the MVB protocol. Currently, there are two main ways to configure MVB: [0003] The first is the direct configuration of the configuration file. That is, the configuration parameters of the MVB are stored in a readable and writable file. When the MVB is started, the configuration of the MVBC (Multifunction Vehicle Bus Controller) is completed according to the stored configuration parameters. However, because ...

Problems solved by technology

[0006] (1) Due to the need to implement a special transmission protocol, that is, both the configuration and the MVB implementation components need to implement the configuration protocol, so there are many devices and conditions that need to be relied on and the requirements are high, which increases the difficulty of using MVB, and the portability and scalability Poor scalability;

[0007] (2) The configuration of MVB needs to rely on configuration instructions. If the MVB component is down during operation or there is a problem with the transmission part, the entire configuration system cannot operate normally, so the reliability of the configuration is not high;

[0008] (3) When the configuration is changed, the components storing the MVB configuration items need to be restarted, and the MVB will also stop communicating until the startup is completed, so it takes a long time to stop using the MVB during the reconfiguration process
