Problems solved by technology

[0004] Existing UHF RFID identification equipment is one-to-one single interaction mode, which cannot meet the application of some special occasions. To realize many-to-many or one-to-many applications, the current solution can only add UHF RFID identification equipment. Undoubtedly increase the economic burden of users and the complexity of project construction

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] 1. Logical structure of the present invention

[0035] Such as figure 1 As shown, the overall structure of a "soft multi-core" application solution for a UHF RFID reader mainly includes: a radio frequency module, a protocol stack, business logic, and an adaptation interface.

[0036] RF module: mainly includes RF antenna switching module, RF receiving and transmitting module, RF modulation and demodulation module.

[0037] Antenna switching module: when multiple antennas work, it mainly completes the switching work of antennas. It adopts "single-pole four-throw" radio frequency switch, and the switch selection control is completed by software setting.

[0038] For example, "00" "01" "10" "11" controls four switches, which correspond to antenna 1, antenna 2, antenna 3 and antenna 4 respectively. In the present invention, only two switche...

Abstract

The invention discloses a multinuclear UHF RFID reader-writer realized by application software. The reader-writer mainly comprises: 1, a radio frequency module which comprises a radio frequency antenna switching module, a radio frequency transceiver module, a radio frequency modulation-demodulation module and a plurality of antennas; 2, a protocol stack which is used for carrying out coding and decoding of relevant protocols and route selection is connected to a business logic layer and acts on the radio frequency modulation-demodulation module of the radio frequency module; 3, the business logic layer which comprises an embedded OS and a multinuclear application mode based on the embedded OS; and 4, an adaption interface which is the communication interface of the reader-writer and a control terminal. Based on realization of multiple cores, according to the invention, a multi-protocol multi-label identification function is achieved; a distributed task processing mechanism is realized for the first time; performance of the reader-writer is effectively improved; and resource of the reader-writer is fully utilized.

Description

technical field [0001] The invention relates to a UHF RFID reader-writer, in particular to a multi-core UHF RFID reader-writer realized by application software. Background technique [0002] Radio frequency automatic identification (RFID) technology is a new technology that has been emerging in the world in recent years and has been rapidly promoted and applied. [0003] The radio frequency identification device sends a microwave query signal to the object equipped with the electronic tag through the microwave antenna. After the tag receives the query signal from the reader, it will reflect the data information in the tag back to the reader according to the command requirements in the query signal. It is a brand-new method launched to automatically collect characteristic data such as attributes, states, and numbers of objects for the realization of digitization and informatization, and can be widely used in the automatic identification of people, animals, and objects.
