Reversing radar working principle

Click:    date:1970-01-01 08:01:00

 

Reversing radar, also known as the parking assist system,or reversing the computer alert system. It is a safetyauxiliary device of car parking or reversing, ultrasonic sensors (commonly known as the probe), the controller and display (or buzzer) parts. It can use sound or a more showsaround the obstacles of this pilot intuitive, lifting the driver's parking, and start the vehicle when reversing around the problems caused by the visit and help the driver to remove the vision, dead and blurred vision defects, improve driving safety.

Reversing radar now available in the market are mostly used in ultrasonic ranging principle, the driver in the car,the automobile gear onto the R block, start reversing radar,under the control of a controller, a device in the rearbumper on the probe transmits ultrasonic, obstacle,produce back wave signal, the sensor receives the echosignal after the controller for data processing, which calculated between the vehicle and the obstacle distance,determine the position of the obstacle, the display shows the distance and send out warning signals, which allows the driver to reverse without hitting obstacles. The whole process, there is no need to drive back the situation after the car, stopping and reversing it easier, more secure.

Specifically, reversing radar working principle is: first, the power and open, vehicle into reverse gear, the detector automatically enter the host state, while the band is on display. Then, holes in the bumper using special drill, and detectors were put into the hole. According to owners of the habit of reversing and parking, detector four probes were installed in the car or the tail on both sides of the installation of two. Host detectors installed in the appropriate position, will display the folder in the rearview mirror on the car, began to work properly.
