The full name of infrared beam detector is photoelectric beam detector, and its basic structure includes aiming hole, beam intensity indicator, spherical lens, LED indicator and so on. The detection principle is that infrared light is transmitted to a long distance through LED infrared light emitting diode, and then focused by optical reflector and received by receiver. When the light is blocked, an alarm will be given. Infrared ray is a kind of invisible light, which will spread to form a cone beam when projected. Infrared light emits 1000 beams per second, so it is a pulsating infrared beam. Therefore, these opposites cannot be transmitted over a long distance (within 600 meters). When someone crosses the monitoring protection zone, the detector using beam blocking method will block the invisible infrared beam and trigger an alarm. Often used for outdoor fence alarm, always used in pairs: one transmitting and one receiving. The emitter emits one or more infrared rays invisible to human eyes, forming a warning line. When an object passes by, the light is blocked, the receiver signal changes, and an alarm will be given after amplification. The infrared crosstalk probe should choose the appropriate response time: too short is easy to cause unnecessary interference, such as birds flying by and small animals passing by; If it is too long, it will not be able to report. The shortest shading time is usually determined at the speed of10 m/s. If the width of a person is 20cm, the shortest interruption time is 20 ms.. More than 20ms alarm, less than 20ms no alarm. Infrared correlation detectors are widely used in urban security, residential areas, factories, companies, schools, families, villas, warehouses, resources, petroleum, chemical industry, gas transmission and distribution and many other fields.
