本论文详细介绍了基于单片机的热释电防盗报警系统的设计。论文从硬件和软件两方面对系统进行了设计,包括核心芯片的选型,外围电路的连接,芯片与芯片之间的连接电路,程序设计方法和相应的软件。系统电源使用7805、7809芯片输出5V、9V电压,并通过稳压模块为系统供电。整个设计采用了模块化思想,主机采用AT89C51实现控制,通过热释电传感器和振动位移传感器自动监测住宅的模拟信号,如人体发出的红外信号和引起的振动信号。一旦检测到异常情况,传感器将产生数字信号输入单片机,单片机则根据输入信号输出给蜂鸣器进行报警,并做出相应的反应处理。复位电路采用低功耗、四引脚的IMP812监控芯片。系统硬件电路简单、安装方便、操作简单,并且具有成本低的优点,可适用于各种类型的住宅和人群。

The design covers both hardware and software aspects, including the selection of the core chip, the connection of the peripheral circuit, the interconnection circuit between chips, programming methods, and corresponding software. The system is powered by the 7805 and 7809 chips, which output 5V and 9V voltage, and is supplied power through a voltage regulator module. The entire design adopts a modularized approach, with the main unit controlled by the AT89C51. It automatically monitors the analog signals of the residence using pyroelectric sensors and vibration displacement sensors, such as infrared signals emitted by the human body and vibrations. When an abnormal situation is detected, the sensors generate digital signals input into the microcontroller, which then outputs an alarm to the buzzer and reacts accordingly. The reset circuit uses a low-power, four-pin IMP812 monitoring chip. The system's hardware circuit is simple, easy to install, and operate, and it has the advantage of being cost-effective, making it suitable for various types of residences and populations.
Keywords: Sensor; Microcontroller; Alarm system.
