摘要
为精确测得应用于电子标签防盗系统(EAS)中的电子防盗标签的质量参数,根据标签的结构,提出了利用互感耦合原理对标签的质量参数进行检测的方法。研究了单线圈传感器模型和双线圈传感器模型结构特点,并分别对其进行了M atlab仿真分析。同时对双线圈传感器进行了设计制作和实验测试。研究结果表明,双线圈传感器检测效果好,而且该传感器现已成功应用于电子标签检测系统中。
In order to measure the quality parameters of the electronic anti-theft label used in an electronic article surveillance（EAS） system,according to its structure,the method utilizing the principle of mutual inductance to measure the quality parameters was thought out.The features of the model of monocoil sensor and double-coil sensor were studied,and their simulation on Matlab was made out.Finally,a double-coil sensor in lab was produced,and its test was carried out with good effect.The senor has been successfully applied in detection system of anti-theft label.
