防紅外偽裝網的防紅外偵測原理是什么?
What is the principle of anti infrared detection for anti infrared camouflage nets?
主動式紅外線報警器由發射機和接收機兩部分構成。
The active infrared alarm consists of a transmitter and a receiver.
其中,發射機包括電源、發光源、光學系統等組成部分,在電源的作用下,紅外發光二極管發射紅外光束,經光學系統作用變成平行光發射出去。
Among them, the transmitter consists of components such as a power supply, a light source, and an optical system. Under the action of the power supply, the infrared light-emitting diode emits an infrared beam, which is then converted into parallel light and emitted by the optical system.
接收機包括光學系統,放大器,光學傳感器,信號處理器等組成部分。 負責接收發射機發射出的紅外線,并經光電傳感器將光信號轉換成電信號,經信號處理器分析處理后傳給報警控制器。
The receiver consists of optical systems, amplifiers, optical sensors, signal processors, and other components. Responsible for receiving infrared radiation emitted by the transmitter, converting optical signals into electrical signals through photoelectric sensors, and transmitting them to the alarm controller after analysis and processing by the signal processor.
主動式紅外線報警器就是利用發射機發射紅外線,而接收機接收紅外線來工作的。在發射機與接收機之間形成了一條紅外警戒線,在正常情況下,發射機發射紅外線。
An active infrared alarm is a device that uses a transmitter to emit infrared radiation, while a receiver receives infrared radiation to operate. An infrared warning line is formed between the transmitter and receiver, and under normal circumstances, the transmitter emits infrared radiation.
