Abstract

With the continuous development of sports events, the scoring and recording methods of basketball games are gradually moving towards automation and intelligence. The traditional scoring method has problems such as tedious manual operation and easy errors, so developing an efficient and accurate automatic scoring device for basketball games has important practical significance.

This design aims to achieve automation and intelligence of basketball scoring through modern electronic technology and Internet of Things technology, improving the smoothness and fairness of the game. This design uses STM32F103C8T6 microcontroller as the control core, and utilizes multiple sensors and modules to achieve real-time monitoring and data processing of the competition process. The system adjusts the game time, starts and stops, adds points, and switches venues through buttons. It uses DHT11 temperature and humidity sensors to monitor the temperature and humidity of the game environment, uses infrared obstacle avoidance modules to detect whether the basketball hits, and automatically turns on the lighting through the lighting detection module when the lighting is insufficient. By using TTS voice to report scores, buzzer reminders at the end of the game, and voice score reporting functions, and transmitting game data to the mobile phone through WiFi module, it is convenient to view the game situation in real time.

After functional testing, the automatic scoring device for basketball games can accurately record the game time, scores of each team, and monitor the temperature, humidity, and lighting conditions of the game environment in real time. The device is easy to operate, responds quickly, has high reliability and practicality, and can effectively improve the scoring efficiency and game experience of basketball games.

In the future, with the continuous advancement of technology, we hope to introduce artificial intelligence and machine learning techniques into this device, further optimize scoring algorithms, and achieve more accurate basketball hit detection and game data analysis. At the same time, by combining real-time weather and venue conditions, more scientific suggestions and strategies are provided for the game, bringing a more intelligent and convenient experience to basketball games.
