摘　　要：讨论了C语言在测控系统软件开发中应用的方法及其相应技术。提出了一种利用STD总线工业控制机自身的定时器/计数器产生定时中断来控制数据采集的方法,给出了应用时的编程技术和具体的C语言源程序。本文所讨论的时间中断技术、TSR技术、嵌入汇编技术和多任务技术具有一定通用性,其程序有很好的移植性。The present papes discusses the method and technique of C Language applied in the development of measurement and control software. It is proposed that data acquisition is controlled by the timing interrupt which is generated by the timer or counter of industrial control computer with STD bus. The programing technique and detailed C Language source code program are given out. The techniques, such as time interrupt, TSR, inlaying assembly and multi—task discussed in this paper are of common use, and the corresponding program is very easy to transplant.
