摘要
在各类体育赛事中，精准的记分和计时对保证比赛公平性、提升赛事专业性具有重要意义。传统的手动记分牌依赖人工记录比分和控制时间，不仅效率低下、易出现记录错误，还存在时间控制不精准、操作繁琐等问题，难以满足各类赛事对高效管理的需求。
基于 STM32F103C8T6 单片机的红外遥控式双屏记分牌，整合了 OLED 显示模块（主机和从机）、红外接收模块、按键及电源管理模块，实现了赛事记分与计时的自动化管理。系统核心功能包括：通过主机 OLED 显示屏实时显示甲队和乙队的比分，从机 OLED 显示屏同步展示比赛时间；支持红外遥控操作，可设置比赛时间、控制时间的开始、停止和归零，同时实现甲队、乙队比分的增减；配备物理按键作为备用操作方式，确保在遥控失效时仍能正常操作。
该系统的实现，有效提升了赛事记分计时的准确性和操作便捷性，减少了人工干预带来的误差，为赛事管理人员提供了高效的辅助工具，同时为同类体育器材的智能化升级提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous development of sports events and the increasing demand for standardized competitions, accurate score recording and time management are of great significance for ensuring the fairness of competitions and improving the efficiency of event organization. Traditional manual scoreboards have many limitations in use, such as relying on manual scorekeeping which is prone to errors, difficulty in synchronizing time and scores, and inconvenient operation that affects the smooth progress of competitions, making it difficult to meet the needs of modern sports events.
The infrared remote-controlled dual-screen scoreboard based on STM32F103C8T6 microcontroller integrates OLED display modules (host and slave), infrared remote control module, and timing control circuit, realizing intelligent score management and time control for sports events. The core functions of the system include: displaying the scores of Team A and Team B through the host OLED display module, with clear and intuitive data presentation; showing the game time through the slave OLED display module, supporting time start, stop and reset operations; using the infrared remote control to set the game time, control the start/stop/reset of the game, and adjust the scores of both teams (increase or decrease), ensuring convenient and quick operation.
The implementation of this system effectively improves the accuracy and efficiency of score recording and time control in competitions, reduces the error rate caused by manual operation, and ensures the synchronization of score and time information. It provides a reliable auxiliary tool for sports event organizers and referees, and also offers a reference for the development of similar sports equipment, with high practical application value.
