Abstract

The invention discloses a train software partitioning and integrating method. The method comprises the following steps: a storage step of programming a boot loader U-Boot into a flash memory through a simulator; a starting step of starting the U-Boot; a downloading step for downloading the bootstrap program, the root operating system and other sub-operating systems in the ROM foremost area by accessing the internet access; an activation step for activating the bootstrap program; a step of allocating CPU resources, an independent RAM region and an ROM region; a starting step for starting the root operating system; a starting step for starting the sub-operating system; a step of downloading the component, the configuration file and the application program in the corresponding ROM area by accessing the internet access; a starting step of loading the universal component to run in the RAM area; a starting step of loading the application software to run in the RAM area; and an operation step of periodically accessing each partition.

Description

technical field [0001] The invention relates to the field of train control systems, in particular to a train software partition and integration method. Background technique [0002] The train control system is the guarantee for the safe and effective running of the train. The existing train control system is composed of many subsystems, such as traction, braking, display screen, door control, etc. The subsystems are physically isolated, and each subsystem consists of a set of Complete hardware and supporting software complete specific functions, and then realize data interaction through MVB, Ethernet, CAN and other network communications. Therefore, the current disadvantages of the train control system are: waste of hardware resources, high software memory, and inconvenient data exchange between systems. [0003] Therefore, in order to save hardware resources, save memory space, and simplify data transmission between systems, a new train software partition and integration m...
