The car reserving aid system is also called "Reversing anti-collision radar", it is the automobile safe parking auxiliary unit, which can use sound or a more direct demonstration to show the driver the obstacle situation around. Thus relieve the difficulty of looking ahead and back when parking or starting vehicles, and help the driver to eliminate the dead angle of the field of vision and the flaw of sight.
This paper introduces a micro-miniaturization, digital display and acousto-optics alarm intelligent parking radar that based on MCU AT89C52.The back-draft radar develops on the basis of ultrasonic ranging principle. It uses the the optimized software and hardware technology, the result obtained will be delivered to the digital tube and showed. At the same time, the acousto-optics alarm will work. The driver only has to sit in the cab and can know fairly well. Thus the riving security and efficiency enhance enormously.
