摘　　要：随着科技的飞速发展,人们的生活水平和安全意识都得到了极大的提升,因此,各种防盗报警器应运而生,以满足人们对安全日益增长的需求。因红外光的不可见性、隐蔽性、保密性等特点,在防盗、报警等安防系统中得到广泛应用。以热释电红外传感器为接收元件的被动式红外报警电路,采用双探测元的探测方式,通过分析各电路功能与工作原理,利用Multisim 14软件完成各电路及系统仿真,分析各电路的输入输出波形,最终实现报警功能,提高了报警的灵敏度,达到了安全防患的目的。With the rapid development of science and technology,people's living standards and safety awareness have been greatly improved,so a variety of anti-theft alarms have emerged to meet people's growing demand for security.Because of the invisibility,concealment and confidentiality of infrared light,it is widely used in security systems such as anti-theft and alarm.With a passive infrared alarm circuit with a pyroelectric infrared sensor as the receiving component,using the detection method of a dual detection element,through the analysis of the functions and working principles of each circuit,this article uses Multisim 14 software to simulate each circuit and system,and analyzes the input and output waveforms of each circuit,so as to finally realize the alarm function,improve the sensitivity of the alarm,and achieve the purpose of safety prevention.
