摘　　要：介绍了以Cygnal 8051 F330单片机为控制器,用于汽车倒车的超声波测距模块的硬件电路和软件设计方案,在抗干扰设计等方面该模块采用了软硬件综合处理措施,实现了较高的测距精度和较宽的测距范围。在满足倒车系统要求的基础上,体现了简单、经济、实效、实用的特点,文章给出了该模块的实际调试效果和误差分析结果。An personally designed ultrasonic distance-measuring system is introduced and its hardware circuits and software design methods are given in this paper, which bases on Cygnal 8051 F330 single chip, and is applied to carbacking system. In the system, some improvement on both hardware and software is adapted, which makes the system has better precision and wider measuring range. Moreover, besides its capability of satisfy the requirement raised by car-backing system, the system has other characters such as briefness, economy, actual effect, practicality etc., The practical debugging results and error analyzing results are given at the end of this paper.
