摘要
在体育教学与训练中，立定跳远成绩的精准测量对评估运动员体能及提升训练效果至关重要。传统的立定跳远测试依赖人工测量和判断，存在起跳位置判定不准、测量误差大、数据记录繁琐等问题，难以满足现代体育测试对精准性、高效性的需求。
基于 STM32F103C8T6 单片机的立定跳远测试系统，整合了分离式红外传感器、超声波传感器、语音模块、按键、OLED 显示屏及 WiFi 模块，实现了跳远过程的自动监测、距离测量及数据上传。系统核心功能包括：通过分离式红外检测运动员起跳位置，若超过红线则触发声光报警；借助超声波传感器检测跳远距离（以超声波到红外线模块的总长度减去超声波测得距离计算），并通过语音播报距离；通过按键可设置超声波模块到红外线模块的总长度；OLED 显示屏实时显示测量值；数据交互方面，通过 WiFi 模块将测量数据发送到手机端，手机端也可设置总长度。
该系统的实现，有效提升了立定跳远测试的自动化、精准化水平，通过自动监测、实时显示、语音播报及手机端管理，为立定跳远测试提供了便捷、高效的解决方案，同时为体育测试设备智能化领域的发展提供了参考，具有较高的实用价值与推广意义。

ABSTRACT
In physical education and training, the accurate measurement of standing long jump results is crucial for evaluating athletes’ physical fitness and improving training effectiveness. Traditional standing long jump tests rely on manual measurement and judgment, which have problems such as inaccurate judgment of take-off position, large measurement errors, and cumbersome data recording, making it difficult to meet the requirements of modern physical education tests for accuracy and efficiency.
The standing long jump test system based on STM32F103C8T6 microcontroller integrates a separate infrared sensor, ultrasonic sensor, voice module, buttons, OLED display and WiFi module, realizing automatic monitoring of the long jump process, distance measurement and data upload. The core functions of the system include: detecting the athlete’s take-off position through the separate infrared sensor, triggering an acousto-optic alarm if it exceeds the red line; detecting the long jump distance with the help of the ultrasonic sensor (calculated by subtracting the distance measured by the ultrasonic from the total length from the ultrasonic module to the infrared module), and broadcasting the distance through voice; setting the total length from the ultrasonic module to the infrared module through buttons; the OLED display shows the measured value in real time; in terms of data interaction, the measured data is sent to the mobile phone through the WiFi module, and the mobile phone can also set the total length.
The implementation of this system has effectively improved the automation and precision level of standing long jump tests. Through automatic monitoring, real-time display, voice broadcast and mobile phone management, it provides a convenient and efficient solution for standing long jump tests. At the same time, it provides a reference for the development of the intelligent field of physical education test equipment, and has high practical value and promotion significance.
