摘要
为提高基于射频识别(RFID)技术的机场行李自动分拣系统的正确性和实时性,提出了一系列措施,包括:为读写器设计具有楔形辐射范围的有向天线;通过功率调节使读写器天线视距覆盖范围内最多仅含一个标签;采取多帧重复识别机制滤除环境反射干扰;采用小帧长。实验测试表明,行李识别正确率可达99.89%且符合实时性要求,所提出的综合性技术措施具有实用价值。
In order to enhance the correctness and fast response of the baggage handling system based onradio frequency identification（RFID） technology in airports,a series of measures are proposed,includingdedicated design of the directional antenna of the reader to make a chock shaped coverage area,adjustingthe transmitting power to make sure that not more than one tag exists in the line-of-sight radiation field ofthe reader＇s antenna,reading tags repeatedly through multiple frames to filter interference from reflection byenvironments,and adopting small frame length. Experimental tests show that the ratio of correct identification reaches 99. 89 percent while the real-time nature is guaranteed,so that the proposed comprehensivetechnical measures have practical value.
