Design of the Time and Score of Basketball Competition Based on Single Chip Computer

In the basketball competition,timing-score system is indispensable.With the competition rules further perfected,the corresponding timing-score systems must be improved as well.The design of hardware and software of competition timing-score system is achieved using 89C51,the system not only has the functions that the total time is set by software and the total countdown is achieved,and according to the rules,offensive side should make a shooting action in 24 seconds,otherwise be regarded as illegal,so a 24 second count down system is needed,but also the scores of two sides are recorded on the scoreboard.The timer button operation and LED display are used in this design.The part of software is edited and debugged.In the end,software and hardware are combined well.Modular design,simple process structure,clear mandate and easy to prepare,debug and modify are applied.
