Embodiment Construction

[0026] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] figure 1 A flowchart of a data filtering method according to an embodiment of the present invention is shown.

[0028] like figure 1 As shown, the data filtering method according to one embodiment of the present invention includes: S1, at least one RFID reader collects data of a preset type in at least one RFID tag, and transmits the collected data to the middleware; S2, the middleware collects the data Inputting a preset finite state machine model, determining invalid data in the collected data according to the output data of the preset finite state machine model, and filtering and / or merging the invalid data.

[0029] Preferably, the middleware includes: device middleware and filter middleware, and the step S2 includes: the device middleware transmits the collected data to the filter middleware, and the filter middleware transfers the The col...

Abstract

The invention relates to a method and system for data filtering. The method for data filtering comprises a first step of utilizing at least one RFID reader to collect data of a preset type in at least one RFID label and transmit the collected data to middleware; and a second step of utilizing the middleware to input the collected data in a preset finite state machine model, determine invalid data in the collected data according to output data of the preset finite state machine model and filter and / or merge the invalid data. According to the technical scheme, by utilizing the middleware, a finite state machine mode is adopted to effectively eliminate interference caused by labels outside the system, redundant label data in the system are integrated, valid label data are screened out to be rapidly effectively analyzed, and the risk caused by system misreading is also reduced.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a data filtering method and a data filtering system. Background technique [0002] RFID radio frequency identification technology (Radio Frequency Identification) has the advantages of automatic identification, rapid detection, and reduced human resource costs. It has been maturely applied to many industries, such as: logistics industry, pharmaceutical and health care industries, libraries, contactless ID cards And tickets, asset management, manufacturing, apparel industry, automotive industry, animal identification, traffic management, aerospace, military, etc. The wide application of multiple industries also brings higher requirements for RFID data. [0003] In order to realize the wide application of RFID technology, the application system based on RFID technology often uses cheap and low-power RFID tags and equipment to control the cost of the entire s...
