测控系统的发展是社会进步与更新换代的共同需求，是计算机技术在实际环境中的有效实践。特别是总线技 术的应用，极大地提高了测控系统的工作效率，加强了稳定性，拓展了应用范围，为新技术的推广打下了良好的基础。本文从 测控系统中计算机总线的结构入手，分析了总线在数据驱动中的应用，以期能为总线技术的教学提供一些有益的经验。

The development of measurement and control system is the common demand of social progress and upgrading. It is the effective practice of the computer technology in the practical environment. Especially, the application of bus technology greatly improves the efficiency of the measurement and control system, strengthening the stability and expanding the application scope, laying a good foundation for the promotion of the new technologies. This paper introduces the structure of the computer bus in the measurement and control system, and analyzes in the application of bus in data driven, hoping to provide some experience for bus technology teaching.
