测控技术与仪器 摘 要 红外线热释电和超声波遥控电路由于其功耗低，可靠性高和互相干扰小等优点，已经在现实生活中得到了广泛的应用，而热释电红外控制在各类和安全防护系统的检测中更有着独特的作用。红外控制电路组成的热释电红外控制照明灯。电子开关VT导通驱动固态继电器SSR开通本设计的核心是通过热释电红外探头RE200B探测，以热释电红外传感器和少量外接元器件构成被动式的热释电红外开关能自动快速开启了解和掌握它们的工作原理和电路结构该控制器能实现有人进入灯亮，人走灯灭控制。常用于许多公共场所，如办公室、楼道和厕所浴室、储藏室、梳妆台镜前灯等自动控制。 关键词：热释电红外传感器; 红外热释电处理芯片1; 红外辐射 ABSTRACT Infrared, pyroelectric and ultrasonic wave remote control electric circuit, because of its low power loss, the high reliability and slightly mutually disturbs .It is already widespread in application in the real life, but the pyroelectric infrared control has the unique function in each kind of security warning equipments and in safety systems examination. Therefore,it is essential to understanding and grasping the working principle and the circuit structure. In this paper, it was designed a well hidden passive infrared alarm which was based on the pyroelectric infrared processing chip BISS0001. The core of the design was detecting human intrusion with Pyroelectric infrared sensor RE200B.Passive pyroelectric infrared switch is combine with Pyroelectric infrared sensor a small number of external components. It would open the sound and light alarm,which combined with light-emitting diode and the buzzer automatically and quickly, and timing controlled by the MCU. After the test,the measuring range of alarm apparatus may reach 1m, the survey angle may reach 100°-120°, the sensitivity is high, the rate of false alarm is small, antijamming ability, has served the safety protection purpose.
