Embodiment Construction
[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific implementation examples and with reference to the accompanying drawings.
[0043] A kind of basic event filtering method for RFID label dynamic information management described in the present invention, its method is by setting up a basic event table for each reader-writer, described comprising steps as follows:
[0044] Step S1: using the priority queue set for storing the collected RFID data streams established according to the priorities of the readers in the RFID data stream collection stage;
[0045] Step S2: Using the constructed priority queue set, by maintaining a basic event table for each reader, extract the collected RFID data stream stored in the priority queue in the constructed priority queue set Basic events, so that the RFID data streams collected by high-priority rea...

The invention discloses a method for filtering elementary event facing RFID (Radio Frequency Identification) label dynamic information management, comprising the following steps of: in order to satisfy the requirement that elementary event is filtered timely for collected RFID dataflow, building a priority queue set for storing the collected RFID dataflow in the RFID dataflow acquisition phase; extracting the elementary event from the collected RFID dataflow stored in the priority queue in the built priority queue set by using the built priority queue set and maintaining one elementary event list for each reader-writer, preferentially filtering so that the elementary event is preferentially filtered for the collected RFID dataflow collected by the high-priority reader-writer, communication load between the reader-writer and an upper computer is reduced at the same time, and the instantaneity of RFID label dynamic information management is improved.
Description
technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a basic event filtering method for dynamic information management of RFID tags which is helpful for improving dynamic information management of RFID tags. Background technique [0002] RFID (Radio Frequency Identification, Radio Frequency Identification) is a non-contact automatic identification technology that automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in harsh environments. The information collection and information service system based on EPC coding technology, RFID technology and Internet technology, its application can improve the management level of the entire supply chain and production operations, in automatic warehouse inventory management, product logistics tracking, automatic supply chain management, product assembly...
