基于单片机的带有汉字显示及语音播报的超声波测距系统设计--毕业论文

摘 要测量作为各领域一个重要的工具，有着悠久的历史。在我国，早在秦始皇时期就已经统一了度量衡，推行“一法度衡量丈尺，车同轨，书同文字”，并制定了一套严格的管理制度。同样，测量的方法及使用的仪器也有着纷繁复杂的选择，比如有游标式测量仪器，机械式测量仪器，电学式测量仪器等。随着科学技术的进展，超声波测量法在众多测量方法中脱颖而出，由于超声波具有方向性好，穿透性强，尤其是在光不透明的固体中，它碰到杂质或分界面就有显著的反射等优点，超声波测距在测量中的应用越来越广泛，笔者设计的是一个多功能的带有汉字显示及语音播报的超声波测距系统。本文系统介绍了一种基于单片机 CC2530 的带有汉字显示及语音播报的超声波测距系统。整个电路采纳模块化设计，硬件部分由超声波测距模块、单片机模块、温度传感器模块、语音播报模块、LCD 显示模块组成，软件部分由测距发送模块，播报显示模块组成 。本文给出了详细的软，硬件设计方案。本超声波测距仪 测量距离0.20m~5.00m，测距精度±1㎝，具有汉字显示及语音播报等功能，测量时与待测物体无直接接触，具有整体性好，精度高，可靠性好，控制简单方便等特点。本设计完成实物的制作，实物效果能达到设计要求。关 键 词 ：测距仪，单片机，超声波， TMP275 温度传感器， Nokia5110 液晶显示器,WT588DABSTRACTAs a significant tool in various fields, measuring has a long history. In China, it can date back to the period of Qin Shi Huang, who standardized the system of weights and measures, promoted “Apply the same system of measuring methods and tools, the same road width and the same written language”, and also formulated a set of strict management system. Similarly, measuring methods and equipment also have a complicated choice, such as vernier measuring equipment, mechanical measuring equipment and electrical measuring equipment etc. With the development of science and technology, the ultrasonic measurement method has stood out from numerous measuring methods. As it has the advantages of good direction and strong penetrability, especially in the opaque objects, it c...
