为降低宿舍火灾和偷盗事件发生的概率，保障人类生命财产安全。本文采用软硬件结合方式，设计一款操作简单、经济适用的宿舍防火防盗报警系统。硬件采用AD进行设计，选用是STM32为主控芯片；选用烟雾、红外人体、温度等传感器件，进行数据采集模块的设计；选用蜂鸣器和LED灯，进行报警模块的设计；选用按键和OLED显示模块相互配合，进行预设值、实时监测值的设置和显示。软件采用KeiluVision4进行设计，设计好主程序和子程序，用主程序调用子程序，完成程序的修改和调试。实物测试表明，在烟雾浓度、温度不低于预设值和有人入侵的情况发生时，都会发出声光报警，并控制继电器启动水泵进行灭火，当检测到需要进行指纹开锁时，通过继电器控制门锁打开，本设计基本实现了系统预设的功能。该系统及时有效的了解火灾的特点及报警措施，为预防火灾和偷盗事件、降低经济财产损失，具有重大意义。

ABSTRACT
In order to reduce the probability of dormitory fire and theft, to ensure the safety of human life and property. In this paper, hardware and software are combined to design a simple and economical dormitory fire alarm system. The hardware is designed with AD, and STM32 is selected as the main control chip. Smoke, infrared body, temperature and other sensors are used to design the data acquisition module. Buzzer and LED lights are selected to design the alarm module. Buttons and OLED display module are selected to cooperate with each other to set and display preset values and real-time monitoring values. KeiluVision4 was used to design the software. The main program and subprogram were designed, and the subprogram was called by the main program to complete the modification and debugging of the program. The physical test shows that, when the smoke concentration and temperature are not lower than the preset value and someone invade the situation, the sound and light alarm will be issued, and the relay will be controlled to start the water pump to extinguish the fire. When fingerprint unlocking is detected, the door lock will be opened through the relay control. This design basically realizes the preset function of the system. The system timely and effectively understand the characteristics of fire and alarm measures, in order to prevent fire and theft events, reduce economic property losses, has great significance.
