RFID天线场强的测试与研究
摘要
射频识别(RFID)作为一项先进的自动识别和数据采集技术,被认为是21世纪十大重要技术之一。它利用射频信号通过无线传输的方式,在读写器和电子标签之间进行数据交换和目标识别。目前RFID技术已经在社会的很多领域得到了应用。
本文主要论述RFID读写器天线场强的测试方法。在RFID读写器天线场强简易测试系统中,通过选用相关的仪器,在读写器上方一定距离的测试平面内,利用测试线圈采集一个测试平面内的场强,直接读取天线的场强值。在读写器天线场强测试的基础上,进一步研究了加入手机后读写器场强的变化。
在RFID读写器天线场强三维扫描系统测试中,详细论述了基于高性能AVR单片机ATmega32的RFID场强测试系统的设计原理以及具体的设计方法。该系统以ATmega32单片机为控制中心实现了对信号的采集、放大、存储、显示等功能,使测试过程变得更加方便和准确。通过串行接口将数据传输到上位机,在上位机测试软件中实时显示出测试结果的二维图形。该系统并且具有较高的抗干扰性及测试结果的可重复性。
Radio Frequency Identification (RFID) as a technology of advanced automatic identification and data collection is considered to be one of important technologies in the 21st century.,which exchanges data and distinguishes object between the reader and the electronic tag using radio frequency signals via wireless transission means.RFID technology has been applied in many areas of society at present.
This paper mainly discussed the methods of RFID reader antenna field testing. During the field testing of RFID reader antenna, a simplified testing system was designed.In the plane,some where away from the reader,souple the field by test coil and by selecting related equipments, data of the antenna field were directly read. Based on field testing, field changing when binding to the mobile phone was further researched.
During discussing 3D scan of the antenna field of RFID reader, the design principle and method for RFID antenna field test system based on high performance AVR MCU was proposed in detail, and many functions such as acquisition,enlarge, storage, display were achieved with the control core of ATmega32 microcontroller, which made the testing process more convenient and accurate. The resulting data were transmitted to PC by serial interface and shown on computer with a two-dimensional graphics.This system is quite immunity and the resute is repeatable.
