Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0015] In the present invention, the universal RFID reader-writer platform is used as the core hardware platform, and the host computer is used as the core control platform. The host computer acquires label information data by controlling the universal RFID reader-writer platform, collects label information data by controlling the data acquisition card, and feeds back to the host computer. . Finally, the upper computer judges the movement direction of the label through the data obtained by analyzing the matlab program, and the matlab program is packaged as an executable file, which makes the movement direction judgment convenient and quick.

[0016] The present invention mainly covers four parts: a host computer part, a universal RFID reader-writer platform, a data acquisit...

Abstract

The invention provides a dual antenna tag moving direction identification method based on a universal RFID reader / writer platform. The universal RFID reader / writer platform is used as the core hardware platform, and the host computer is used as the core control platform. The host computer acquires the tag information data by controlling the universal RFID reader / writer platform, collects the tag information data by controlling the data acquisition card and feeds it back to the host computer. Finally, the host computer analyzes the acquired data to judge the movement direction of the tag. The invention utilizes the phase difference between the tag and the two antennas and adopts the phase compensation to simplify the judging basis, which can realize the identification of the movement direction of the tag with small calculation amount and convenience, and, at the same time, there is no need to consider various influences of the electromagnetic wave from the emission to the reflection, thus increasing the robustness of the system.

Description

technical field [0001] The invention belongs to the technical field of RFID and relates to a method for identifying the moving direction of a double-antenna tag. Background technique [0002] Radio frequency identification technology is a new technology emerging with the development of embedded and wireless communication, and has become a hot topic now, mainly used in the field of automatic identification and positioning. Among them, the radio frequency identification system (RFID) is widely used in large warehouse supermarkets and vehicles, railway automatic identification systems and indoor positioning due to its advantages of low power consumption, low cost, non-line-of-sight, non-contact, and long transmission distance. [0003] The traditional identification method of label movement direction uses RCS calculation method and Foles space formula calculation method to calculate the distance, and judges the movement direction according to the distance change. The commonali...
