Embodiment 1

[0083] Referring to the structure of the RFID reader-writer shown in Figure 1, referring to the block diagram of the event management structure shown in Figure 2, in this example, the processing chip is selected AT91RM9200 chip, the radio frequency transceiver is selected SkyeTek M9, the RAM memory is HUNIX, FLASH memory It is SAMSUNG, a PC (as a server, the minimum configuration is Pentium4, CPU 1.0GHz, memory 512MB, operating system is Windows XP). The tag event of the RFID tag captured by the AT91RM9200 processor includes the tag ID number, the time when the tag was read, and the data carried by the tag.

[0084]The RFID tag event received by the ARM processor is a binary stream of information. The event management process that the ARM processor carries out to the captured RFID tag event is illustrated by an example below: (the configuration configuration of the filter is shown in Figure 3)

[0085] 1. Repeat filter

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 ...
