Management system for reader-writer to read RFID label event

Abstract

The invention discloses a management system used for a reader to read RFID label event; wherein the reader comprises a central processing unit, a signal receiving unit, a signal transmission unit, a memory, a task management module and an event management module stored in the processor. The central processing unit takes an ARM processor as core, which comprises a 32M RAM; a radio frequency transceiver is adopted by the signal receiving unit and the signal transmission unit. The memory comprises an RAM memory and a FLASH memory; wherein the signal receiving unit and the signal transmission unit are controlled by the RAM processor through an asynchronous serial interface to realize radio-frequency signal transceiving and capture the label event of the RFID label. Then the ARM processor is communicated with a host computer or a server through an Ethernet interface. The invention has the advantages that various different field real-time tasks customized by users can be supported and effectively dispatched by the task management module and the event management module, thereby deployment of the field real-time tasks, edge business process and business decision can be realized by the intelligent apparatus.

Description

technical field [0001] The present invention relates to a kind of RFID (radio frequency identification) reading and writing equipment, more particularly, refers to a kind of management system for reader-writer to read RFID tag event, especially this reader-writer through the management of RFID tag event It can optimize the performance of the EPC system, increase network traffic, avoid network congestion and overload of information network systems, and support the deployment of on-site real-time tasks. Background technique [0002] Patent application number 200710098525.3 discloses a "portable radio frequency identification reader", which includes a radio frequency transceiver module and a digital baseband processing module (single chip microcomputer) connected to it. The output end of the digital baseband processing module is connected to the signal input end of the radio frequency transmitter, and the digital baseband processing module is bidirectionally connected with the ...

AI Technical Summary

Problems solved by technology

[0005] (1) With the massive increase of tag data captured by the reader-writer, if the reader-writer does not have data processing and computing capabilities, the data communication volume of the EPC information network system will increase rapidly, and a large amount of garbage data will lead to the deterioration of the overall performance of the EPC system. drop, especially in a wireless network environment

[0006] (2) In the traditional EPC system architecture, all business processes and business decisions must be executed on the middleware server or application server. The reader / writer only has the function of simple data reading and writing, and cannot support some real-time features well. Highly demanding on-site tasks greatly limit the expansion of the EPC system in the application field
