Beam switching method of radio frequency tag reader, radio frequency identification system and storage medium

The invention discloses a beam switching method of a radio frequency tag reader, a radio frequency identification system and a storage medium. The method comprises the steps that the reader adopts a first beam antenna to detect a radio frequency tag identification blind area; calculating a required second beam antenna according to the radio frequency tag identification blind area information; and the reader carries out beam switching according to the first beam antenna and the second beam antenna and carries out radio frequency identification according to the beam switching. According to the invention, the problems of misreading and misreading and too long multi-antenna scanning time caused by the fact that an electronic tag with a weak signal cannot be identified in a large coverage range in the prior art are solved. 本发明公开了射频标签阅读器的波束切换方法、射频识别系统及存储介质，其方法包括步骤：阅读器采用第一波束天线检测射频标签识别盲区；根据射频标签识别盲区信息计算所需的第二波束天线；阅读器根据第一波束天线和第二波束天线进行波束切换并以此进行射频识别。本发明解决了相关技术中无法在较大覆盖范围内识别较弱信号的电子标签导致漏读错读及多天线扫描时间过长的问题。
