Configuration file generating and updating method and system based on dynamic link library

Abstract

The invention provides a safety control unit configuration file generating and updating method based on a dynamic link library. The method comprises the steps that S1, configuration files corresponding to all application programs in a trackside / vehicle-mounted equipment safety control unit are stored in corresponding static arrays respectively; s2, the static arrays are packaged into correspondingfunctions, different static arrays correspond to different functions, and a dynamic link library is generated based on the functions; s3, the dynamic link library is transmitted to a board card through a burning tool and a network, and the dynamic link library is burned to a storage module of the board card; and S4, a corresponding function in the dynamic link library is called for the process ofthe application program in the security control unit, a corresponding configuration file in the function is obtained, and the configuration file is provided for the process.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment safety control unit configuration files, in particular to a method for generating and updating a safety control unit configuration file based on a dynamic link library. Background technique [0002] At present, trackside / vehicle devices and the like need to load highly configurable and flexible configuration files corresponding to the application to realize the specific functions of the application. For example, for core ground safety equipment such as the train control center and temporary speed limit server, the system initialization and normal function realization require the support of relevant configuration files. The current configuration files are basically manually configured by data producers. When the number of trackside equipment and on-board equipment increases, the manual configuration method will have a sharp increase in inefficiency and insecurity, and cannot adapt t...

Problems solved by technology

[0005] The safety control unit must read each binary configuration file each time. When a file is large, it will occupy a large amount of memory space on the board and affect the performance of the safety control unit; when multiple applications need to obtain the corresponding configuration file When the configuration file is uploaded to the board, it is usually directly uploaded in plain text, which poses a great security risk.
