摘要
随着汽车保有量的不断增长，车辆安全防护需求日益凸显。传统的车辆防盗方式多依赖机械锁或简单电子报警，存在防盗精度低、响应滞后、无法远程监控等问题，难以应对复杂的盗窃手段和用户对实时安全掌控的需求。
基于 STM32F103C8T6 单片机的智能车辆防盗系统，整合了 DS18B20 温度检测模块、D203S 人体检测模块、震动监测模块、按键、OLED 显示屏、4G 模块及声光报警装置，实现了车辆的全方位智能防盗监测与远程控制。系统核心功能包括：通过 DS18B20 检测车辆环境温度，温度过高时触发声光报警；通过 D203S 检测车门周围是否有人，布防状态下监测到人时启动声光报警；通过震动监测模块感知车内震动，布防时检测到震动即触发声光报警并发送短信；支持通过按键设置温度最大值和布防操作；通过 OLED 显示屏实时显示温度、人员检测状态、震动状态；借助 4G 模块将监测数据传输至手机端，手机可远程设置布防和撤防。
该系统的实现，有效提升了车辆防盗的智能化与实时性，通过多维度监测和远程通信，让用户能随时掌握车辆安全状态，及时接收异常报警，为车辆安全提供了可靠保障，同时为同类智能安防系统的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous growth of car ownership, the demand for vehicle security protection has become increasingly prominent. Traditional vehicle anti-theft methods mostly rely on mechanical locks or simple electronic alarms, which have problems such as low anti-theft accuracy, delayed response, and inability to remote monitoring, making it difficult to cope with complex theft methods and users’ demand for real-time security control.
The intelligent vehicle anti-theft system based on the STM32F103C8T6 microcontroller integrates DS18B20 temperature detection module, D203S human detection module, vibration monitoring module, buttons, OLED display, 4G module and acousto-optic alarm device, realizing all-round intelligent anti-theft monitoring and remote control of vehicles. The core functions of the system include: detecting the vehicle’s ambient temperature through DS18B20, triggering an acousto-optic alarm when the temperature is too high; detecting whether there is a person around the car door through D203S, and activating the acousto-optic alarm when a person is detected in the armed state; sensing vibrations in the car through the vibration monitoring module, and triggering an acousto-optic alarm and sending a text message when vibration is detected in the armed state; supporting the setting of maximum temperature and arming operation through buttons; real-time display of temperature, human detection status, and vibration status through the OLED display; transmitting monitoring data to the mobile phone through the 4G module, and the mobile phone can remotely set arming and disarming.
The implementation of this system effectively improves the intelligence and real-time performance of vehicle anti-theft. Through multi-dimensional monitoring and remote communication, users can keep abreast of the vehicle’s security status and receive abnormal alarms in a timely manner, providing reliable protection for vehicle safety. At the same time, it provides a reference for the research and development of similar intelligent security systems, with high practical application value.
