摘 要本课题将嵌入式类型的智能倒车雷达系统作为了研究对象，在研究过程中对这种系统的发展过程以及发展现状进行了广泛的研究，根据相关产品所能表现出的功能和性能，确立了本课题的设计内容。本文选用了一款性价比极高的 AT89C51 单片机芯片来作为主控器件，结合了 LCD1602 液晶显示屏、有源蜂鸣器、HC-SR04 测距模块和SC8035 语音播报芯片等一些常见器件，设计出了一款具有较高性能的智能倒车雷达系统，实现了对车辆后方障碍物的距离测量、距离过近报警、真人语音播报以及液晶显示等功能。这款系统的实现降低了市面上大多数产品的研发成本，更为重要的是解决了这些产品所表现出的普遍弊端，不但能够长时间稳定工作，工作过程中还不容易受到环境因素的干扰，经过了多种方式的系统测试之后，这款系统将所有的预期功能都得到了实现，如果能够将它推向市场，具有非常积极的意义。关键词： 倒车雷达；语音辅助；AT89C51 单片机；超声波测距；AbstractIn this paper, the embedded intelligent backing radar system is taken as the research object. In the research process, the development process and development status of this system are studied extensively. According to the functions and performance of related products, the design content of this subject is established. In this paper, an AT89C51 chip with high cost performance is selected as the main control device, combined with LCD1602 LCD display, active buzzer, HC-SR04 ranging module and SC8035 voice broadcasting chip and other common devices, a high performance intelligent backing radar system is designed, which realizes the rear of the vehicle. Distance measurement of obstacles, proximity alarm, human voice broadcast and LCD display. The implementation of this system reduces the cost of research and development of most products on the market. More importantly, it solves the common drawbacks of these products. It can not only work stably for a long time, but also is not easily disturbed by environmental factors. After a ...
