摘要
简述了利用RFID导盲的基本原理,给出了导盲杖的总体结构并设计了相应的硬件模块,选择了适合于户外RFID导盲的电子标签。主要探讨了在RFID导盲系统中如何合理铺设电子标签的问题,给出了相应实验方案,即把17张电子标签以一定间距垂直嵌入到盲道的地缝中,在盲道上行走的盲人通过手中的导盲杖探测电子标签,在到测到标签并听到提示音之后再走下一步。实验中采用不同的电子标签间距,进行了大量实验并记录了相应数据。基于实验数据分析,得出了铺设电子标签的合适间距在35～45cm之间的结论。
The basic principle of RFID blind navigation is introduced simply.The structure of blind navigation cane is given and the relevant hardware module is designed.And RFID tags being fit for RFID blind navigation are chosen.It is mainly discussed that how to place tags appropriately in RFID blind navigation.And it gives the relevant experimental method that a blind man walks the next step after discovering RFID tag and hearing the sound cue through blind navigation cane in the blind road where 17 RFID tags are embedded at regular intervals.A lot of experiments are finished at different tag intervals and relevant data are recorded.At last,based on the statistical analysis,draw the conclusion that the appropriate tag interval is between 35 cm and 45 cm.
