Embedded data concentrator based on RFID middleware

Abstract

The invention relates to an embedded data concentrator based on RFID middleware and belongs to the technical field of the radio frequency identification technology. The embedded data concentrator comprises embedded data concentrator hardware and configuration management software. The embedded data concentrator hardware works in an embedded hardware environment based on an ARM and comprises a processor, a memory, a wireless module, a display screen and a universal input / output interface, and the hardware is integrated on two double-layer hybrid integrated circuit boards, wherein one hybrid integrated circuit board integrates the processor, the memory and the display screen, and the processor is connected with the memory through a main memory bus and connected with the display screen through an I / O bus; the other hybrid integrated circuit board integrates the wireless module and the universal input / output interface, the wireless module and the universal input / output interface are respectively connected with an I / O bus of the circuit board, and the two circuit boards are in the mode of a master and a slave and are connected through a UART bus. The embedded data concentrator has the advantages that the RFID data integration problem is solved; an RFID system generates a large amount of data, the data are processed through the RFID middleware, valuable RFID data are transmitted to an enterprise, and thus the RFID technology and an enterprise resource information system can be combined.

Description

technical field [0001] The invention belongs to the field of RFID radio frequency technology, in particular to an embedded data concentrator based on RFID middleware. Background technique [0002] Radio frequency identification technology RFID is an automatic identification technology that uses radio frequency to conduct non-contact two-way communication and exchange data to achieve identification purposes. With its unique advantages, RFID technology is gradually being widely used in the fields of industrial automation, commercial automation and transportation management. [0003] RFID systems generally consist of readers, electronic tags and enterprise application systems. In practical applications, there are many protocols, and RFID products produced by different manufacturers have different programming interfaces, and each reader may have a few usage and operation methods, which become obstacles for enterprises to apply RFID systems; at the same time, if the The informa...
