智能家居安防系统的设计与制作 [摘要]本设计主要以单片机 AT89S51 为智能控制中心，结合烟雾检测模块、火灾检测模块、人为非法入侵检测模块与声控报警模块，与其外围辅助电路，构成了一个集防盗、防火、防毒气等多种检测功能为一体的多功能防盗报警系统。首先由各传感器检测烟雾、火灾与人为非法入侵信号，当检测到的信号超出自身的设定值时，将其转化为电信号并传送给单片机处理，再由单片机将电信号传送给蜂鸣器驱动其报警。该系统具有轻便灵巧、电路简单易实现，所使用的各类元器件灵敏度较高的特点。利用单片机编程，可使电路功能易于控制，从而实现了识别不同警情的具有智能报警的家居报警系统。[关键词]AT89S51 单片机; HC-SR501；DS18B20 数字温度模块；智能报警：热释电Design of Intelligent Home Furnishing Security System [Abstract]This design mainly with AT89S51 single chip computer as the control center, combined with smoke detection module, fire detection module, human intrusion detection module and the voice alarm module, and its auxiliary circuit, constitutes a set anti-theft, fire, gas and other detection the multifunctional anti-theft alarm system.First of all , the sensors detect smoke, fire and human intrusion signal, when the detected signal exceeds the set value, the sensors will transform it into an electric signal and transmit it to the MSC for processing, and the transmit electrical signals will be transmitted to the alarm buzzer for driving. The system is portable and flexible, the circuit is simple and easy to implement, used by various components of high sensitivity characteristic. The use of MSC programming, can make the function of the circuit is easy to control, thus realizing the pyroelectric sensor to detect illegal invasion, gas sensor for detection of gas and other harmful gases, temperature sensor for detecting the fire.[Key words] AT89S51; HC-SR501；DS18B20；MQ-2目 录引言 11.系统方案设计 21.1 报警系统的组成...
