Online reloading method for software programs of security computer platform

Abstract

The invention discloses an online reloading method for software programs of a secure computer platform. The platform is divided into a main control layer and an execution layer. The main control layeris composed of a main control module A and a main control module B. The execution layer provides a communication interface with external equipment and an external sub-module. The execution layer is composed of two groups of execution modules A and execution modules B. Each master control module and each execution module of the secure computer platform comprise a bootstrap program and other software programs. The security computer platform provides a software debugging interface. The software on the main control module and / or each execution module is updated through the debugging interface ofthe security computer platform to realize online reloading of software programs. According to the technical advantages of the online reloading method, an extremely flexible software reloading method is adopted, so that all module software can be updated by any sub-module. The guide software is combined with software structures of other software. The software does not need to be updated manually. The safety and maintainability of safety computer platform software are improved.

Description

technical field [0001] The invention relates to the field of realization of a railway safety computer platform, in particular to a method for changing the software programs of each module in the safety computer platform. Background technique [0002] With the development of railway transportation, the development of train signal control related equipment is diversified. Higher requirements are placed on the safety and versatility of train control equipment. As a basic general-purpose platform, the safety computer can be flexibly developed and integrated with various input and output modules, and supports various application environments. It is characterized by layered and bus architecture, each layer contains relatively independent modules that can be integrated, each module can contain software programs, and the modules can communicate through the bus. The existing software program replacement method uses an emulator to program, that is, each module in the safety computer...

AI Technical Summary

Problems solved by technology

The existing software program replacement method uses an emulator to program, that is, each module in the safety computer needs to be programmed separately using an emulator. The existing replacement method has complex operations, cumbersome manual operations, and a high probability of error big disadvantage
