摘要

Integration sensors into radio frequency identification (RFID) system is a technology progress trend. In the sensing RFID system which RFID system integrates with sensors, diversity of sample requirements in practical application scenes determines that one physical sensor in the sensing tag must implement multiple logical sensors functions. Based on the sensing RFID system, the paper defines the multiple logical sensor's function, and produces the parameters configuration solution of the physical sensor. The paper also studies the memory mode of logical sensors' data in the sensing lag, the operation mechanism of logical sensors' and their algorithms. With this solution of multiple logical sensors, the author develops a sensing RFID system for monitoring the temperature, humidity, vibration and theft prevention of the items in the container, and achieves success in the experiments.%射频识别(radio frequency identification,RFID)与传感器技术的融合是当前物联网技术发展的必然趋势.在传感器与射频识别融合的传感射频识别系统中,现实应用需求的多样性决定了传感标签中一个物理传感器要实现多个逻辑传感器功能.基于传感射频识别系统,主要研究了传感标签中逻辑传感器的功能定义,逻辑传感器采样参数的配置,同时也研究了逻辑传感器数据在传感标签中的存储模式、逻辑传感器的运行机制和逻辑传感器功能的算法实现.采用该多逻辑传感器研究方案,开发了一套传感射频识别系统,用于监控集装箱内物品温度、湿度、振动和防盗,取得了良好的效果.
