Design method of locomotive computer controller based on RTEMS real-time operating system

Abstract

The invention discloses a design method of a locomotive computer controller based on an RTEMS real-time operating system. The design method comprises the following steps: 1, proposing implementation schemes of establishing various sub-items of software cross compiling development environment, RTEMS real-time operating system transplantation and the relevant device driver design; 2, building the software cross compiling development environment; 3, achieving a series of goals, including the generation and installation of operating system images, and the guidance of the operating system on a hardware platform; and 4, writing a driver for hardware devices such as a dual port RAM, a CAN bus module, a serial port module and an Ethernet module, and verifying the feasibility of the entire system software and hardware design scheme by running various special test programs on the hardware platform of a locomotive computer. According to the design method of the locomotive computer controller based on the RTEMS real-time operating system disclosed by the invention, peripherals are managed by using the open source protocol stack of the device, and thus the development difficulties can be greatly reduced.

Description

technical field [0001] The invention relates to a design method, in particular to a design method of a locomotive computer controller based on an RTEMS real-time operating system, and belongs to the technical field of computer intelligent control. Background technique [0002] The use of embedded computers as the core controller of the locomotive is a future development trend. With the continuous improvement of the functions and performance of the locomotive itself, the locomotive control system has become more and more complex. Through the investigation of embedded products, it is found that directly in the Software development on complex embedded computers usually has the following problems: poor software portability, when the controller hardware is changed, the software code designed on the basis of the original hardware cannot run on the new hardware platform, resulting in a lot of waste of preliminary work; Embedded computers are rich in peripheral resources, and variou...

[0002] The use of embedded computers as the core controller of the locomotive is a future development trend. With the continuous improvement of the functions and performance of the locomotive itself, the locomotive control system has become more and more complex. Through the investigation of embedded products, it is found that directly in the Software development on complex embedded computers usually has the following problems: poor software portability, when the controller hardware is changed, the software code designed on the basis of the original hardware cannot run on the new hardware platform, resulting in a lot of waste of preliminary work; Embedded computers are rich in peripheral resources, and various peripheral resources require complex protocols to work normally, and the work of writing related software is quite arduous; the computer controller needs to complete many functions, and has requirements for real-time performance, multi-tasking and real-time performance There are constraints, and it is necessary to coordinate the contradiction between multitasking and real-time
