在本文中，我们提出了一个系统，利用无线射频识别（RFID）的盲人的援助。所提出的系统将移动的RFID读取器模块与集成的ZigBee收发器[1]结合，用于传输标签的信息。房屋或建筑物中的器具和其他物体嵌入有无源RFID标签（应答器），沿着有音频文件，该音频文件为每个物体记录并且对于每个物体是唯一的，驻留在服务器上。该系统还采用了通过使用充足的分离区域的RFID标签网格[4]的寻路技术。读取器读取标签并将数据无线传输到服务器PC，服务器PC继而扫描数据库中的特定ID并播放相应的音频文件。具有服务器端路由应用的自行设计的坐标系统用于基于人的当前标签坐标将人路由到所请求的特定房间。使用FM发射器将音频播放无线中继到带FM接收器的耳机或智能手机的FM收音机。通过在巴基斯坦白沙瓦政府盲人研究所部署拟议的系统，测试了所开发系统的可行性和可靠性[6]。
In this paper, we have presented a system utilizing Radio Frequency Identification (RFID) for the assistance of blind people. The proposed system incorporates a mobile RFID reader module with an integrated ZigBee transceiver [1] for transmitting the tag's information. Utensils and other objects in the house or building are embedded with passive RFID tags (transponders) along with an audio file, recorded for and unique to each object, residing on the server. This system further takes in the way finding technique by employing an RFID tag grid [4] using an ample separation area. The reader reads the tags and transmits the data wirelessly to the server PC which in turn scans for the particular ID in the database and plays the corresponding audio file. A self designed coordinates system with a server side routing application is used for routing the person to a particular room requested, based on his current tag coordinates. The audio playback is relayed wirelessly using an FM transmitter to either a headset with FM receiver or a Smart Phone's FM radio. The feasibility and reliability of the developed system was tested by deploying the proposed system at Government Institute for Blind, Peshawar, Pakistan [6].
