Study of Multiple Logical Sensors in the Sensing RFID System

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 tag, 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.
