基于微控制器的汽车防盗报警系统设计
摘要：当前汽车防盗形势严峻，传统防盗手段存在诸多不足，如无法实时精准定位、对人员靠近监测不灵敏、报警不及时且无法远程通知车主、布防撤防操作复杂、信息展示不直观等诸多问题，设计一款高效可靠的汽车防盗报警系统具有重要意义。
本设计采用基于STM32F103C8T6主芯片模块的系统方案，结合D203S人体热释电检测模块、SW-18015p震动检测模块、4G无线通信模块、GPS定位模块、OLED显示模块以及SRD-05VDC-SL-C继电器模块多传感器及功能模块实现了车辆位置获取、人员监测、震动及启动报警、布防撤防与启停控制、数据实时显示以及远程数据传输与控制等功能，有效提升了汽车防盗报警的及时性、准确性和便捷性，为车辆安全防护提供了有力保障。
通过实物进行模拟验证，该汽车防盗报警系统能够监测车辆周边潜在威胁，实时触发多级警报机制，全面证实了系统架构的实用价值与运行可靠性。

Design of Automobile Anti-theft Alarm System Based on Microcontroller
Abstract: The current situation of car anti-theft is severe. Traditional anti-theft methods have many deficiencies, such as inability to accurately locate in real time, insensitive monitoring of personnel approaching, untimely alarm and inability to remotely notify car owners, complex arming and disarming operations, and non-intuitive information display. It is of great significance to design an efficient and reliable car anti-theft alarm system.
This design adopts a system solution based on the STM32F103C8T6 main chip module. Combining multiple sensors and functional modules such as the D203S human body thermoelectric detection module, SW-18015p vibration detection module, 4G wireless communication module, GPS positioning module, OLED display module, and SRD-05VVDC SL-C relay module, vehicle position acquisition, personnel monitoring, vibration and start-up alarm, arming and disarming, start-stop control, and data have been achieved Real-time display, remote data transmission and control and other functions effectively enhance the timeliness, accuracy and convenience of car anti-theft alarm, providing a strong guarantee for vehicle safety protection.
Through simulation verification with physical objects, this automotive anti-theft alarm system can monitor potential threats around the vehicle and trigger multi-level alarm mechanisms in real time, fully confirming the practical value and operational reliability of the system architecture.
Key words: Anti-theft alarm; Vehicle location ;Personnel monitoring ;Remote data.
