电子标签传感器的应用及前景分析 摘 要 本文介绍的电子标签技术最初在技术领域，应答器是指能够传输信息回复信息的电子模块，近些年，由于技术发展迅猛，应答器有了新的说法和含义，又被叫做智能标签或标签。电子标签电子电梯合格证的阅读器（读写器）通过天线与电子标签电子标签进行无线通信，可以实现对标签识别码和内存数据的读出或写入操作。典型的阅读器包含有高频模块（发送器和接收器）、控制单元以及阅读器天线。　电子标签是一种非接触式的它通过自动识别目标对象并获取相关数据，识别工作无需人工干预，可工作于各种恶劣环境。电子标签技术可识别高速运动物体并可同时识别多个标签，操作快捷方便。?广泛应用于各个领域，但其标准化、防冲突算法、系统测量精度都有待于进一步提高。针对的优缺点及其发展方向进行系统研究。阐述了的安全性和高效、快速识别算法等优点；介绍技术和物联网、无线传感器、NFC等技术的结合，以及技术在零售、物流、交通等领域的应用。通过综合分析国际各制造商在技术的应用研究，给出我国未来技术的发展趋向。实时准确获取农产品在供应链环节中的环境参数是农产品安全可追溯系统透明化的瓶颈之一.技术可与传感器技术相结合,应用于农产品质量安全追溯系统,对温度、湿度等重要参数进行检测、记录,并通过无线通信的方式进行识别本文综述了集成传感器电子标签的国内外发展现状,分析了技术关键点,指出了目前存在的问题以及解决问题的建议  Abstract In this paper, the technology of electronic label first in technical fields, the response is to point to to transmit information reply information, electronic module, in recent years, due to the rapid development of electronic tag technology, a new statement transponder telemetry and meaning, also called smart labels or label. Electronic tag electronic elevator certificate reader (reading and writing implement) through the antenna and electronic tag electronic tags for wireless communication, which can make the label identification number and memory of data read or written operation. The typical reader contains a high frequency module (transmitter and receiver), control unit and reader antenna. Electronic tag is a non-contact automatic identification technology rf signal through its automatic target recognition and access to relevant data, identify work without human intervention, and it can work in all kinds of environments. Electronic tag technology can identify the moving objects and can also identify multiple tags, the operation is fast and convenient. Electronic tag technology is widely used in many fields, but its standardization, anti-collision algorithm, system measurement accuracy are yet to be further improved. In view of the electronic tag and the advantages and disadvantages of the system and its development direction. Real-time accurate for agricultural pro
