基于红外测距传感器的倒车雷达系统设计
摘要： 本文介绍了一种基于红外测距传感器的倒车雷达系统。采用stc12c5a60s2单片机控制，涉及传感器、液晶显示、zigbee无线通信等多个方面的知识。阐述了倒车雷达系统的结构组成、硬件电路以及软件设计，并在电压值和距离的处理部分采用非线性修正，提高了倒车雷达系统的精度。实验表明，该系统工作稳定，测量精确，成本低，使用简单，可广泛用于汽车防撞系统。
abstract： a reversing radar system was established based on infrared distance sensor in this paper. the whole system is controlled by a single chip microcomputer stc12c5a60s2， related to sensor， lcd display， zigbee wireless communications， and other aspects of the purple peak. detailed description on structure composition of the system and design of hardware circuit and software are presented. the no-linear revision is used to the processing section of the voltage and the distance which improves the precision of the system. experimental results shows that the system work stable， measuring accuracy， low cost， simple to use， can be widely used in automotive anti-collision system.
