摘要本文基于RFID技术设计导盲系统。系统硬件由单片机、阅读器模块、电子标签、语音合成和播放模块及存储器模块五大部分组成。其中单片机用于对整个系统进行控制,负责处理数据,下达命令等,本文选用的单片机为MSP430F123;阅读器与电子标签进行射频耦合以读取电子标签中存储的信息,本文选用的阅读器芯片为TRF7961;电子标签用于存储位置信息,随着标签容量的逐步扩大,除了道路信息外,标签还可以存储周围建筑物、公共设施信息;语音合成和播放模块主要负责将有意义的信息合成为语音并播放,以帮助视力残疾者安全行进;存储器用于存储一些常用语,以减轻标签的存储压力。用C语言编写了部分应用程序,通过大量试验发现标签的距离和人的迈步距离长短相近时标签利用率和导盲杖引导速度都较大,并再此结论基础上设计出了合理方便的盲道。6430

Title the research of the guide system based on RFID technology
Abstract
The article designs the guide system based on RFID technology.the hardware of the system is consist of single-chip microcomputer(SCM),the reader module, the electronic tag, the speech synthesis and play module and the memory module. SCM is used for controlling whole the system ,processing data,ordering commands,and so on. The article selects MSP430F123 for the single-chip microcomputer. the reader reads the information stored in tags for rf coupling.electronic tags are used for storing location information.This paper chooses the chip of TRF7961 for the reader. With the capacity of the tag is gradμAlly enlarged, besides location information, the tag also can store the information of buildings and public facilities around it. Speech synthesis and play module is used for compositing the meaningful information and playing to help the blind walk safely; memory module is used for storaging some phrases to reduced the burden of the memory module. The article also writes part of application programs with C.Though a series of experiments,founding that when the length between 2 tags is close to the length of hunan’s steps,the utilization of tags and the speech of guide rod are high. So on the basis of that,the article designs reasonable convenient lanes.
