Active infrared radiation detector and its application development trend

The active infrared radiation detector consists of two parts: receiving and transmitting. The infrared emitter emits infrared light to a receiver installed at a few meters or even hundreds of meters away, and its beam has a single beam, a double beam, or even multiple beams. When the corresponding infrared beam is interrupted, the receiver sends an alarm signal. The receiver is composed of an optical lens, an infrared phototube, an amplification shaping circuit, a power driver and an actuator. The working principle is that the receiver can receive the infrared beam as a normal state, and when an intrusion occurs, the infrared beam emitted by the transmitter is blocked, that is, the phototube receives no infrared light, thereby outputting a corresponding alarm electric signal, and After the shaping is amplified, the switch quantity alarm signal is output, and the alarm signal can be received by the alarm controller, and the linkage actuator is activated to start other alarm devices, such as an audible and visual alarm, an analog electronic map, a television monitoring system, a lighting system, and the like.

Infrared radiation detectors are mainly used in buildings such as fences and buildings with relatively long distances. Compared with infrared radiation barriers, they are more resistant to rain, dust and interference, and are mainly used in home security systems. In the villa and in the single house. Common active infrared radiation detectors have two beams, three beams, and four beams. The distance ranges from 30 meters to 300 meters. Some manufacturers also produce long-distance multi-beam “light walls”, which are mainly used in factories and mines and some special places.In home applications, we use up to 100 meters of products. In this distance, infrared fences and infrared radiation detectors can be used: if it is installed with balconies, windows, aisles, etc., use infrared fences; When installed in a building, a courtyard wall, etc., an infrared radiation detector should be used; when selecting a product, only products larger than the actual detection distance can be selected.

Infrared radiation development trend

1. More stable and reliable: Enhance the ability of the detector to resist RFI or EMI, lightning protection, etc., to adapt to harsh environments;

2. More kinds of functions: such as detector frequency, anti-blocking, anti-spray cover, anti-destruction, etc.;

3. More beautiful, compact appearance: in line with the increasing demand for taste.
