Problems solved by technology

[0007] 1. Single filtering function
For example, only duplicate data filtering is simply implemented, which increases the burden on the system and loses a lot of useful information
[0008] 2. Not taking the attribute and behavior changes of tags as one of the basis for filtering
[0009] 3. No use of existing EPC and other network information for real-time information filtering processing, unable to provide higher-level services for enterprise application systems, and this is the dense area of ​​useless data
[0010] The above shortcomings lead to the weak function of the traditional middleware filtering system, insufficient filtering, large data redundancy, and poor service ability

Embodiment Construction

[0028] The present invention uses tag data filtering as an independent module in the RFID middleware, and its goal is to realize a configurable pipeline filter. The RFID application system has two layers of filters. The reader hardware device itself has a first-level filtering function, which can filter low-level events such as multiple repeated readings (they are generally implemented in firmware in RFID readers). After the hardware device completes the first layer of filtering of tag data, it transmits the legal data to the middleware that manages it, and the middleware software completes the second advanced filtering. This layer of filtering should be configurable first, that is, users can customize a set of filtering parameters and filters according to their needs, so as to achieve the purpose of filtering specific tag data. Secondly, this layer of filtering is closely related to specific practical applications, and its filtering parameters are generally different for dif...

Abstract

The invention provides an electronic tag data filtering method used for a radio frequency identification middleware. The middleware sequentially filters according to the source, type, coding range, behavior type and entity attribute of an electronic tag. The method comprehensively considers the attribute, behavior information and EPC network information of the tag, greatly reduces the redundant data and realizes the efficient screening of data.

Description

technical field [0001] The invention relates to the field of radio frequency identification (RFID) technology, in particular to a method for filtering electronic tag data in an embedded radio frequency identification middleware (RFID Middleware) system in a weak environment, which is suitable for limited hardware resources, real-time and accurate RFID middleware applications with high performance requirements and large data volumes. Background technique [0002] The middleware software is used to manage the reader and process the electronic tag (EPC) data obtained from the reader, and is also responsible for transmitting these data to the database system in the background. The middleware filters, summarizes and distributes the tag data before sending it to the enterprise application system, and reduces the amount of data that needs to be transmitted. Among them, data filtering is the key technology of electronic tag data processing. On the one hand, it can reduce redundant ...
