Method and device for filtering tag events of middleware of RFID (Radio Frequency Identification) application system

Abstract

The invention relates to middleware of an RFID (Radio Frequency Identification) application system and belongs to the field of the application of RFID. A method for filtering tag events of the middleware of the RFID application system is characterized by comprising the following steps: (1) a tag acquisition device acquires electronic tag data from RFID readers and sends the data to a redundant tag event filter; and (2) after receiving the tag data, the redundant tag event filter extracts reader flags, antenna flags and information on acquisition time from the tag data, filters tag data which come from the same RFID reader or the same antenna and repeatedly appear in a designated time period, and then, outputs effective tag data. According to the invention, through hierarchical multiple electronic tag event filters, the filtering of redundant electronic tag events is achieved, the resources of the RFID application system, which are consumed by diverse electronic tag events, are lowered, and the efficiency of the RFID application system is increased.

Description

Technical field [0001] The invention relates to a middleware of an RFID application system, in particular to a method and device for filtering tag events of the middleware. Background technique [0002] RFID middleware (Radio Frequency Identification middleware) can automatically identify and collect the electronic tag data of RFID equipment, and it is widely used in various logistics, manufacturing, and important item tracking fields. [0003] In the RFID system, the RFID application module realizes the corresponding business logic by receiving the tag events reported by the RFID middleware. In a large application environment, there may be hundreds of RFID devices of various types working at the same time. Middleware puts forward very high requirements for the processing of label events. [0004] At present, the usual method for label processing in RFID applications is to receive an ADDITION event and consider that a new label is added to the detection range; [0005] If a DELETION ...

AI Technical Summary

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide a tag event filtering method and device for RFID application system middleware, which solves the problem that the current filtering method cannot make full use of tag event data, and the processing efficiency of the application system cannot be greatly improved , and the defect of indistinguishable tag data from different antennas of the same RFID reader
