摘 要 随着现代信息技术的迅猛发展，技术ABSTRACT With the rapid development of modern information technology, automatic control technology has received a large number of applications in various fields, especially in the industrial process control, aviation, metallurgy, transportation, especially the achievement about the robot. Automatic control technology in everyday life also had a significant impact, including automatic washing machine, automatic rice cookers and other home appliances. But on the whole, the potential for automatic control in fact far been excavated, with the continuous development of society, the deepening of human practice, the application of automatic control can be expected will be more extensive. With the continuous improvement of living standard, SCM is undoubtedly one of the goals people pursue, the convenience it brings is undeniable, but it is its increasingly high demand for modern work scientific research, life and provide better and more convenient facilities need to start from the digital microcontroller technology, all toward the digital control, intelligent control direction. The design described P89V51RB2 experiment with the traditional computer case, compared with the reading easy, accurate, and it contains more comprehensive and use of experimental circuit. Higher Institute for the current needs of the existing basis of the experimental box used to add more features such as assembly language, so that the experimenter to think and collect information through the final master SCM and other related content. ByP89V51RB2Test Box Design and Development, to better understand the characteristics of the microcontroller 51, the microcontroller further grasp the principles of learning and of work to do after a good bedding.
