we mainly introduce the several wave frequency detector: radar detector, infrared detector, ultrasonic wave detector and photoelectric detector, because these are more common.
radar detector is back with a microwave signals and blocked emission signal is analyzed, it is concluded that the state of the vehicle, such as speed, etc.The application and more highway, its advantage is convenient installation, the disadvantage is that will keep out interference, influence the accuracy of detection.
have active infrared and passive infrared detector.Active infrared equipment take the initiative to point to lane, using is blocked or reflected infrared analysis, it is concluded that the state of the vehicle.And passive is thermal infrared principle, rely on receiving thermal infrared object to analyze the vehicle state.
ultrasonic detector, ultrasonic wave with the principle of radar detection is similar, only issue is of high frequency wave detector, and the microwave radar detector.
principle of photoelectric detector with active infrared detector is similar, the difference is that it is to use the photocell to receive interrupt or reflected light.
well, about the wave frequency detection technology we introduced to this, thank you for reading.
