ABSTRACT:Multi-function timing and scoring device is used to solve the problem of the scoring and timing accuracy in the sports game. This device uses single-chip microcomputer AT89C51 to finish the function of recording the time and score, and sent to the display device according to the arrangement digital information, such as large screen display. 

   This article introduces the designing process of the hardware and software system. This system uses single-chip microcomputer AT89C51 as the control core of the design, and the hardware circuit system is made up of the following several parts: driving module, displaying module, key controlling module, buzzer alarming module. The main program has the following functions: initialization Settings, project selection, keyboard scanning and others. 

   This system can be used in a lot of games such as basketball, handball, wrestling, boxing, judo, tennis, badminton and so on. During the games it can quickly collect ,  record, process and display the time and score .It has many characteristics such as low price, stable performance, simple circuit, strong real-time and others. It is suitable for all kinds of schools or small groups which can use it as the time and score recording device. 

Key words: Single Chip Microcomputer ; Timing Device; Scoring Device ; Multi-function
