Design and Implementation of a Reversing Radar System Based on Single Chip Microcomputer
YAN Min
Abstract：A reversing radar system is designed based on MCU STC89C52 to avoid collision in car backing or parking. It is equipped with three buttons to set the alarm distance and a LED digital displayer to tell the distance between the car and the obstacles. When the car is within the alarm distance,the alarm circuit will give out warning signals. Proteus and Keil are first introduced to simulation test and then real test. The testing results show that the reversing radar system is precise in measuring distance within 20 to 400 cm and it enjoys such advantages as simple peripheral circuit,higher reliability and practicability,and the like.
