Abstract
Reversing radar, also known as the parking assist system, or reversing the computer alert system. It is car parking or reversing the safety of assistive devices, ultrasonic sensors (commonly known as the probe), the controller and display, and other components. It is more intuitive to voice or show that inform the driver of the barrier around the situation, lifting the driver's parking, and start reversing vehicles around before and after the problems caused by the visit and help the driver to remove the dead ends and vision blurred vision Deficiencies and improve driving safety.
Now the market reversing radar most of the ultrasonic ranging principle, driving in reverse, the vehicle will be pushed to the Shift R block to start reversing radar, under the control of the controller, installed in the rear bumper on the probe Send ultrasound, encounter obstacles, a signal, sensors after receiving the signal controller for data processing, thereby calculate the body and the distance between the obstructions, determine the location of obstructions, and then from display Show distance and issued warning signal, so that drivers will not hit obstacles when reversing. The whole process, drivers know they do not have to turn around the situation after the car, stopping and reversing it easier and more secure.
This paper introduces a low cost, high-accuracy, micro-miniaturization, digital display and acousto-optics alarm intelligent parking radar that based on MCU PIC16F716.
