智能盲人手杖的设计(任务书,开题报告,论文10800字)
摘要
随着社会的发展人们的生活水平正在不断地上升，许多残疾人士的生活质量也越来越受关注，然而现市场上出现的盲人辅助工具太多只是简单的拐杖为主，并不具备一些比较智能化的功能，本文介绍了一种实用性高、可语音播报前方障碍物、短信上报以及定位的系统，旨在防止使用者迷失方向。
本文首先对智能盲人手杖所需要用到的技术的现状进行了综述，并给出了设计中所采用的方案，接着描述了各元器件的选择方案、硬件设计以及软件设计，最后是总结调试过程。本文设计的智能盲人手杖主要通过发射超声波检测距离，测量前方障碍物与使用者之间的距离，当前方有障碍物时，语音提醒盲人距离信息，GPS模块首先获取到一帧数据，经过数据解析判断数据有效后，把位置信息以及超声波测到的距离一起显示在LCD上，最后能通过一个按键发送经纬度信息。
通过检测，确定本设计所要实现的各个模块功能都已达到预定的相应要求。

Design and Implementation of Intelligent Blind Hand Cane Abstract
With the development of society, people's living standard is rising constantly, and the quality of life of many disabled people is getting more and more attention. However, there are too many blind assistant tools on the market, which are mainly simple crutches, and do not have some intelligent functions. This paper introduces a system with high practicability, which can broadcast obstacles in front of voice, report by short message and locate. The aim is to prevent users from losing their way.
Firstly, this paper summarizes the status quo of GPS and ultrasonic ranging, and gives the scheme adopted in the design. Then it describes the alternative scheme of each component and the package produce. Finally, it summarizes the debugging process. The multi-functional intelligent walking stick system in this paper can detect the obstacles around the users mainly by transmitting ultrasonic wave. When there are obstacles ahead, the voice reminds the blind of the distance information. The GPS module first obtains a frame of data. After data analysis and judgment, the position information and the distance measured by ultrasonic wave are displayed on the LCD. Finally, it can deliver the news of GPS to the family mobile phone in real time by a key.
Through testing, it is resolved that the works of each part to be implemented in this program have arrived the corresponding demand of the project.
Key words: Intelligent walking stick, ultrasonic ranging ,positioning
本设计的整体流程是GPS获取到经纬度信息，经纬度信息经处理后在LCD上显示，同时GSM模块通过按键控制发送经纬度到手机上；超声波测距勘测距离信息，然后语音播报模块播报所测距离；按键设定最小距离，所设的这个距离会与所测到的距离比较，如果所测距离小于所设距离，蜂鸣器报警。
