1、 超声波倒车雷达系统的设计 工 学 部 工学一部 专 业 自动化 班 级 学 号 姓 名 指导教师 负责教师 毕业设计(论文) I 摘摘 要要 倒车雷达是针对日益拥挤的道路交通状况、以及在停车场、车库、街道等比较 狭窄区域,避免车与车,车与人以及车与墙壁等障碍物发生碰撞,摩擦而出现的一 种着眼于倒车防护的汽车防撞系统。随着越来越多的高科技产品逐渐融入了日常生 活中,倒车雷达系统发生了巨大的变化。仿生学、声学等前沿学科的技术的日趋成 熟与实用化,赋予了倒车雷达系统新的的研究方向与意义。本文描述了一个由三个 超声波测距模块构成的,提供语音报警功能的超声波倒车雷达系统。该系统采用凌 阳 16 位单片
2、机 SPCE061A 为核心,分别控制三个超声波模块,每一个超声波测距 模块都被设定面向不同方向,以探测不同方向的障碍物。本系统采用单片机控制时 间计数和超声波的发射和接收,利用超声波回波的间隔时间,得出实测距离。结果 表明该系统具有结构简单、工作可靠、精度高等特点。 关键词:SPCE061A 单片机;超声波测距;语音提示;LCD 显示 毕业设计(论文) II Abstract The back-draft radar is aims at day by day the crowded road traffic condition, as well as in the parking lot,
3、 the garage, the street and so on the quite narrow region, avoids automobile and automobile, obstacle and so on Automobile and person as well as vehicle and wall has the collision, one kind which the friction appears focuses to the back-draft protection automobile collision avoidance system.As well
4、as the high-tech products gradually integrated into the daily life, the Parking Distance Control system has undergone tremendous changes. The Parking Distance Control system has been given the new direction of the research and significance by the developed of the Bionics, Acoustic, etc. This article describes a Parking Distance Control system which contains three ultrasonic ranging modules and the results can be pronounced in real-time. The three ultrasonic ranging modules are set t
