摘要
在道路交通领域，车辆超速是引发交通事故的主要诱因之一，严重威胁道路交通安全与公众生命财产安全。传统的超速检测多依赖固定测速设备或人工执法，存在覆盖范围有限、实时干预能力不足、灵活性差等问题，难以适应复杂交通环境下的动态监管需求。
基于 STM32F103C8T6 单片机的超速控制系统设计（项目编号：mcuclub-dz-1062），整合了红外测速管、OLED 显示屏、按键模块、声光报警模块、继电器、MX1508 电机驱动模块及 ECB02 蓝牙模块，实现了车辆速度监测、参数设置、自动干预及远程控制等功能。系统核心功能包括：通过两个按键调节 PWM 值，驱动 MX1508 模块控制电机转速；利用红外测速管实时测量速度值，当速度超过设置的最大值时，触发声光报警并控制继电器闭合；支持通过按键设置速度最大值；OLED 显示屏实时展示当前速度及设置参数；借助蓝牙模块将测量数据发送至手机端，同时实现手机端对电机转速的远程控制。
该系统的实现，有效提升了超速监测与干预的自动化、智能化水平，通过实时测速、自动报警、参数可调及蓝牙交互，为车辆超速防控提供了高效、灵活的解决方案，同时为智能交通设备的研发提供了技术参考，具有较高的实用价值与推广意义。

ABSTRACT
In the field of road traffic, vehicle speeding is one of the main causes of traffic accidents, which seriously threatens road traffic safety and the lives and property safety of the public. Traditional speeding detection mostly relies on fixed speed measuring equipment or manual law enforcement, which has problems such as limited coverage, insufficient real-time intervention capability, and poor flexibility, making it difficult to meet the needs of dynamic supervision in complex traffic environments.
The design of the speed overrun control system based on the STM32F103C8T6 single-chip microcomputer (project number: mcuclub-dz-1062) integrates an infrared speed measuring tube, an OLED display, a key module, an acousto-optic alarm module, a relay, an MX1508 motor drive module, and an ECB02 Bluetooth module, realizing functions such as vehicle speed monitoring, parameter setting, automatic intervention, and remote control. The core functions of the system include: adjusting the PWM value through two keys to drive the MX1508 module to control the motor speed; using the infrared speed measuring tube to measure the speed in real time, and when the speed exceeds the set maximum value, triggering the acousto-optic alarm and controlling the relay to close; supporting the setting of the maximum speed through keys; the OLED display real-time displays the current speed and set parameters; using the Bluetooth module to send the measured data to the mobile phone, and at the same time realizing the remote control of the motor speed by the mobile phone.
The realization of this system has effectively improved the automation and intelligence level of speeding monitoring and intervention. Through real-time speed measurement, automatic alarm, adjustable parameters, and Bluetooth interaction, it provides an efficient and flexible solution for vehicle speeding prevention and control. At the same time, it provides a technical reference for the research and development of intelligent transportation equipment, and has high practical value and promotion significance.
