Problems solved by technology

[0006] As far as the reading rate is concerned, the existing testing technology can test the percentage of the reading rate in a certain environment, but it cannot provide intuitive data to analyze the reasons why some electronic tags are not recognized. Given an appropriate optimization method for improving the reading rate, it cannot meet the needs of specific application environments

Embodiment Construction

[0021] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 It is a system structure diagram of the present invention, as shown in the figure, the antenna, radio frequency front end, and analog front end are integrated on a system board PCB1, which can be configured with digital baseband and control module, data acquisition module, data memory, interface, power supply and auxiliary module integration On another system board PCB2, PCB1 and PCB2 are connected together through standard interfaces. Antennas, RF front-ends, and analog front-ends are different for different frequencies and different application environments. The system can be adapted to different frequencies and different environments by updating the RF / analog front-end and tag antenna on PCB1; Labels, their PCB2 can be used in common, and different communication protocols can be implemented by updating the configurable digital baseb...

Abstract

The invention specifically provides an electronic tag test system and a test method thereof, and belongs to the technical field of radio frequency recognition. The test system comprises an antenna, a radio frequency front end, an analog front end, a data collecting module, a configurable digital baseband and control module, a power supply, an auxiliary module, a data storage device and an interface thereof. The data collecting module collects the output data of the analog front end, the output data is transmitted to the digital baseband and control module, and temporarily stored in the data storage device, and the interface is connected to a PC after the testing process is completed. The interface controller of the digital baseband and control module controls the interface, and the data temporarily stored in the data storage device is transmitted to the terminal of the PC. The electronic tag test system and test method thereof can real-time record the electromagnetic characteristics of the electronic tag in application environment and variation condition thereof via a system level testing tag, perform theoretical analysis by guiding into a computer via a standard interface, search the reason that the electronic tag is not recognized, provide basis for selecting appropriate optimistic method, and improve the recognition rate of an RFID system.

Description

technical field [0001] The invention relates to a test system in radio frequency identification (RFID), in particular to a testing electronic label for analyzing the recognition rate of the electronic label and a testing method thereof, belonging to the technical field of radio frequency identification. Background technique [0002] RFID technology originated from the "identification friend or foe" technology of Allied aircraft during World War II, and is a non-contact automatic identification technology. The basic radio frequency identification system includes electronic tags (hereinafter referred to as tags) and readers. In 1948, Harry Stockman published "Communication by Means of Reflected Power" in the Journal of the Institute of Radio Engineers, which laid the theoretical foundation for RFID technology. With the development of semiconductor and large-scale integrated circuit technology, the cost of chips has gradually decreased, and RFID technology has entered the prac...
