摘要:
为研究不同距离、偏移和旋转角度对RFID读取率的影响,本文设定标签读取距离(M)5个处理(1 m、2 m、3 m、4 m、5 m)、偏移角度(A) 5个处理(0˚、15˚、30˚、45˚、60˚)、旋转角度(R)4个处理(0˚、90˚、180˚、270˚),针对空载和不同盆栽植物分别进行试验。结果表明:空载条件时标签读取距离、偏移角度的有效范围:当距离为1 m时,偏移角度的有效范围为0˚~60˚,读取率达到98.0%以上;距离为2~5 m时,偏移角度的有效范围为0˚~45˚,读取率达到97.4%以上。当盆栽植物为一品红、小桐子时,标签读取距离、偏移角度和旋转角度的有效范围:距离最远5 m;当距离为1 m时,偏移角度范围为0˚~60˚;距离为2 m~3 m时,偏移角度范围为0˚~45˚;距离为4 m时,偏移角度范围为0˚~15˚;距离为5 m时,偏移角度范围为0˚;当距离为0~3 m时,其旋转角度的有效范围均为0˚~270˚,在此读取范围内其RFID的读取率均达到93.06%以上;当距离为4 m,偏移角度为0˚~15˚时,其旋转角度的有效范围为0˚~90˚,其RFID的读取率均达到82.7%。测定条件相同时,小桐子的读取率高于一品红的读取率。

Abstract: To study the effects of different distances, offset and rotation angle on the RFID read rates, the paper set the tag reading distance (M) 5 treatments (1 m, 2 m, 3 m, 4 m, 5 m), the offset angle (A) 5 treatments (0˚, 15˚, 30˚, 45˚, 60˚) and the rotation angle (R) 4 treatments (0˚, 90˚, 180˚, 270˚). No-load plants and different potted plants were studied. The result show the effective tag reading range and the offset angle in the no-load condition: when the distance is 1 m, the valid range of the offset angle is 0˚ - 60˚ and the reading rate is more than 98.0%; when the distance is 2 to 5 m, the valid range of the offset angle is 0˚ - 45˚ and the reading rate is more than 97.4%. When the potted plants are poinsettias and Jatropha, the effective range of tag read distance, the offset angle and the rotation angle is: The farthest distance is 5 m; when the distance is 1 m, the offset angle range is 0˚ - 60˚; when the distance is 2 m - 3 m, the offset angle range is 0˚ - 45˚; when the distance is 4 m, the offset angle range is 0˚ - 15˚; when the distance is 5 m, the offset angle range is 0˚; when the distance is 0 - 3 m, the effective range of its rotational angle is 0˚ - 270˚. In this reading range, RFID read rate reaches more than 93.06%. When the distance is 4 m and the offset angle is 0˚ - 15˚, the valid range of its rotation angle is 0˚ - 90˚ and RFID reading rate reaches 82.7%. When measurement condition is same, Jatropha reading rate is higher than poinsettia.
