Sensor virtual spreadsheet-based self-descriptive sensing tag system

Abstract

The invention discloses a sensor virtual spreadsheet-based self-descriptive sensing tag system. The system consists of a sensing tag part and a reader-writer part, wherein the sensing tag stores sensor identification data, sensor characteristic data, sensor configuration parameters; all the acquired sensor data adopt a compact structure, and adopts a database table structure to perform description and address indexing; and the reader-writer part provides two templates, namely, one is a compact structure template for spreadsheet data while the other is a coding template of partial data in the virtual spreadsheet, for the analysis of the virtual spreadsheet data. Compared with the prior art, the sensing tag system can solve the problems of the unique identification of the sensor, the characteristic identification of the sensor, the analysis of the sensor sampling data and the like in a process of fusing a radio frequency identification technique and a sensor technique.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, and more specifically relates to a self-describing sensor tag system based on a sensor virtual electronic data sheet. Background technique [0002] The application of radio frequency identification technology can effectively solve the problem of rapid collection of front-end data and unique identification of materials in the supply chain information system. , It is also necessary to control the process status of the items in the container (such as temperature, humidity, vibration and illegal unpacking, etc.), it is difficult to achieve these requirements by simply using radio frequency identification technology, and related sensor technology is required to achieve these requirements, radio frequency identification and sensorless technology Convergence is the realistic requirement and inevitable trend of current technological development and application. [0003] The curren...

Problems solved by technology

[0004] The reader has the following problems when processing data related to digital sensors: ① How does the reader automatically and uniquely identify the types of different sensors in the sensor tag? ② The reader needs to automatically know the sensor type and basic parameters in the sensor tag in order to read The writer can effectively identify the measured physical quantity and configure the sensor parameters; ③After the sensor data collected by the sensor is transmitted to the reader, the reader must have the ability to identify and analyze the relevant sensor data; ④As an open-loop system , the system needs to apply different sensor tags newly developed. The number of sensors and the sensor types in the sensor tags change as needed. The same type of sensor may also use different types of sensors. Subsequent new research sensor The sensor in the tag should be able to be recognized by existing readers

This cannot systematically solve the four problems mentioned above, that is, the reader cannot automatically and uniquely identify the unique identification number of the sensor in the sensor tag, the sensor type and the basic parameters of the sensor, especially the fourth problem, that is, the developed The current sensor label system cannot be used as an open-loop system. The number of sensors and sensor types in different sensor labels in the follow-up research will change as needed, so as to realize the plug-and-play function of smart sensors. The same type of sensor It is also possible to use different types of sensors. The sensors in the subsequent newly developed sensor tags cannot be recognized by the existing readers. Every time a sensor tag is developed, the reader must be upgraded once, and it is not guaranteed to be fully compatible with the previously developed ones. Sensing tags, which can easily cause confusion in the system
