time is often difficult to meet the Bi requirements, referees are higher, and people of the great and input, low precision and large amounts of data stored on the access difficulties. With the constant development of electronic information industry in all walks of life in the SCM is widely used, microcontroller technology continues to

mature technology to enable automatic time Sprint application in reality. Used in the Sprint with electronic timing methods impartial, accurate, fast and efficient other features. Smart sprint timer is the sports information of the important equipment.It implements automatic time track and field sprint race and intelligence, track and field sprint race over the years to solve the difficult problem of artificial time, so timing is more simple, more convenient, more accurate and more efficient. In this paper, 89S51 microcontroller design using smart sprint timer hardware design and software design, details of the timer system of

monitoring equipment hardware design and use of interrupts, interrupt expansion and timer function of timer software technology, and Smart Dash timer use and precautions.
