Abstract：The informationization and intelligentization of sports competition are the inevitable requirements of social development; In order to make the football match chronoscorer have the advantages of powerful function, high versatility, low price, high reliability and strong anti-interference ability, a set of football match chronoscorer system based on STC89C52 single chip computer is designed and developed, which can adjust the game time (three keys), start and stop the game time (one button), and give extra points (one for each team). Press to add 1 point), change venue (one button); The score is broadcast through the TTS voice broadcast module, and the game time and scores of each team are displayed on the display screen. When the game time is over, the buzzer rings for 3s, and the score is reported through the voice module. Keil programming tool was used to design and debug the control program, and the program was copied to the system to realize different control of system functions. Through experimental simulation, the design could fully realize the functions of competition timing, scoring, start, pause, prompt and exchange of venues. Compared with the traditional LED indicator, the LCD12864 LCD display has the function of clear display and multi-purpose drive, and has good practicability; The design can meet the market demand and has good application value.
