Real-Time Measurement and Control System Based on RTLinux

为了提高和解决工业实时测控系统中的实时性与多任务调度问题,提出了将RTLinux引入了工业测控领域的实现方法;从分析研究RTLinux的实现原理和特征出发,详细介绍了一套工业控制计算机测控系统的硬件结构,着重论述了RTLinux应用于工业实时测控系统领域的软件开发过程,成功地实现了一个基于RTLinux的多任务实时测控系统,最后应用速率单调调度算法及其可调度性判定定理,对测控系统实时性和可调度性进行了分析与测试,测试结果满足测控系统的实时性要求。

In order to solve the problem of real--time performance and multi task schedule in industrial real time measurement and control system, a new method of applying RTl.inux into industrial measurement and control system is proposed. Firstly, from the beginning of analysing the implement principle and characteristic of RTLinux, the hardware frame of the industrial personal computer measurement and control system is given in detail. The software development process is described, through which RTLinux is applied to the field of industrial real--time measurement and control is mainly discussed. A multi task real time measurement and control system based on RTLinux is successfully accomplished. Lastly, the real-- time performance and schedulability of the measurement and control system is analysed and measured using the rate monotonic schedule algorithm and its schedulability test theorem. Result of test is satisfying to the requirement of measurement and control system.
