Product common name: Pure voice 4 exploration car reversing radar
First, the working principle of reversing radar
Reversing radar most of the use of ultrasonic ranging principle, the driver in the reverse (stalls pushed to R file, the system starts by the device in the rear of the probe to the rear of the car launch ultrasound, in case of obstruction echo signal, the controller The echo signal control processing to determine the direction and distance of the obstacle.Finally by the display or buzzer to send images and sound tips, so that when the driver reversing the mind, more relaxed and safe.
