超声波测距——设计与应用
根据世界卫生组织的调查,全球有2.85亿人有视觉障碍。另外,据英国广播公司报道,中国有超过800万的煤矿工人和管道工人在光线昏暗的环境中工作。考虑到上述这两个情况,由于能够测距和警报,超声波测距仪器无论是在生活中还是工业上都能起到至关重要的作用。
    该项目开头包括可行性分析与理论研究。其中理论研究部分搜集并整理了超声波的工作原理。在中期,基于STC89C52单片机的超声波模块,对超声波测距仪进行设计,采购所有元件并将其焊接起来。焊接完成后,将编好的软件导入到单片机中,并进行调试。最后对制作完成的超声波测距仪进行精度测试,并采用不同的方法来处理实验数据。对实验数据进行整理和分析之后,对超声波测距仪提出一些优化设计并对本项目提出进一步的研究建议。

ABSTRACT
In recent decades, the technique of ultrasonic range finding, which has been developed from various aspects, are used in distance measuring. Particularly, applying this technique to the helmets in industrial fields enables workers to navigate dark narrow hallways and avoid colliding with objects in front of them. A practical application of such device can be employed by miners and pipe workers. By the same theory, it can be equipped on hats to help blind people avoid hitting hanging obstacles before them. This project will discuss the feasibility and applicability of the application. The data recorded from the experiment will be used to analyze the characteristics of the ultrasonic range finder. Therefore, some optimal designs could be utilized to improve the performance of the device.
KEYWORDS: Ultrasonic wave, Distance Measurement, Single Chip Micyoco, Temperature Compensation
