本文介绍一种被动式红外线控制器(简称红外控制器)。被动式控制不同于主动式的控制。典型的主动式控制如生产流水线上的红外光电开关,它需要有一个近红外发射源和一个红外光电接收控制器,当控制器遮挡一次红外光线,便输出一个信号。被动式控制不需配备红外发射源,而是采用中红外技术,利用热释电传感元件来接收特定的物体(如人体)辐射的红外线作为控制信号,对设备进行自动控制。本文介绍的红外控制器可应用于红外防盗报警器、灯光的自动照明,以及自动门启闭等的自动控制。本控制器的主要技术参数如下: (1)在常温下,当传感器的安装高度为2m时,对速率为0.3～3m/s的人体的有效传感距离为12m (2)传感的视角水平84°,垂直52° (3)能响应的红外波长为8～14μm (4)环境相对湿度≤85％ (5)使用环境-10～+40℃
This article describes a passive infrared controller (referred to as infrared controller). Passive control is different from active control. Typical active controls such as IR switches on the production line require a near-IR emitter and an IR receiver controller that outputs a signal when the controller shields the IR light. Passive control need not be equipped with infrared emission source, but the use of mid-infrared technology, the use of pyroelectric sensing element to receive specific objects (such as human body) as the control signal of infrared radiation on the device for automatic control. This article describes the infrared controller can be applied to infrared burglar alarm, automatic lighting lighting, and automatic door opening and closing and other automatic control. The main technical parameters of the controller are as follows: (1) at room temperature, when the sensor installation height of 2m, the rate of 0.3 ~ 3m / s body’s effective sensing distance of 12m (2) sensing angle of view 84 °, vertical 52 ° (3) Infrared wavelength response is 8 ~ 14μm (4) Relative humidity ≤85% (5) Operating environment -10 ~ + 40 ℃
