摘要
在交通管理领域，对车辆超速行为的精准统计与监管是保障道路安全、减少交通事故的重要手段。传统的超速统计方式多依赖人工执法或固定测速设备，存在统计效率低、覆盖范围有限、数据反馈滞后等问题，难以满足动态交通环境下的精细化管理需求。
基于 STM32F103C8T6 单片机的超速统计系统，整合了 HWFS+HWJS 红外对射管、3 个独立按键、OLED 显示屏、AIR7804G 模块及声光报警装置，实现了车辆速度检测、超速判断、数据统计及远程管理的自动化。系统核心功能包括：通过两对红外对射管测量车辆经过的速度值，当速度大于设置的最大值时，触发声光报警并持续 3 声；支持通过 3 个独立按键设置速度最大值；借助 OLED 显示屏实时显示速度最大值、当前车速、是否超速状态、当前通过总车辆数及超速车辆数；利用 AIR7804G 模块将数据发送至手机端，手机端可远程设置速度最大值。
该系统的实现，有效提升了超速统计的自动化与智能化水平，扩大了监管覆盖范围，确保了数据统计的及时性与准确性，为交通管理部门提供了高效、可靠的超速监管解决方案，同时为同类交通监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
In the field of traffic management, accurate statistics and supervision of vehicle overspeed behavior are important means to ensure road safety and reduce traffic accidents. Traditional overspeed statistics methods mostly rely on manual law enforcement or fixed speed measuring equipment, which have problems such as low statistical efficiency, limited coverage, and delayed data feedback, making it difficult to meet the needs of refined management in dynamic traffic environments.
The overspeed statistics system based on the STM32F103C8T6 microcontroller integrates HWFS+HWJS infrared correlation tubes, 3 independent buttons, an OLED display, an AIR7804G module, and an acousto-optic alarm device, realizing the automation of vehicle speed detection, overspeed judgment, data statistics, and remote management. The core functions of the system include: measuring the speed of passing vehicles through two pairs of infrared correlation tubes, and when the speed exceeds the set maximum value, triggering an acousto-optic alarm that lasts for 3 times; supporting the setting of the maximum speed through 3 independent buttons; real-time display of the maximum speed, current vehicle speed, overspeed status, total number of passing vehicles, and number of overspeed vehicles through the OLED display; sending data to the mobile phone via the AIR7804G module, and the mobile phone can remotely set the maximum speed.
The implementation of this system effectively improves the automation and intelligence level of overspeed statistics, expands the coverage of supervision, ensures the timeliness and accuracy of data statistics, provides an efficient and reliable overspeed supervision solution for traffic management departments, and also offers a reference for the research and development of similar traffic monitoring equipment, with high practical application value.
