Embodiment Construction
[0033] The present invention is described in further detail now in conjunction with accompanying drawing.
[0034] A kind of RFID tag data compression method facing discrete manufacturing workshop proposed by the present invention, such as figure 1 As shown, it includes attribute data compression module, streaming data encoding module, dynamic dictionary module and data decoding module. The attribute data compression module compresses and encodes the material attribute data according to its data characteristics through two steps of sorting, classification and compression encoding, and stores the encoding result in the label, such as figure 2 shown. The circulation data encoding module compresses the circulation data generated during the production and circulation of materials according to the type of data structure, and writes them into tags according to the set storage model, such as image 3 shown. The dynamic dictionary module serves the attribute data compression modul...

The invention relates to an RFID tag data compression method for a discrete manufacturing workshop. The RFID tag data compression method for a discrete manufacturing workshop includes an attribute data compression module, a flow data encoding module, a dynamic dictionary module and a data decoding module, wherein the attribute data compression module classifies material attribute data according tothe characteristics and implements compression coding and storage; the flow data encoding module encodes and stores the flow data generated from the material during the production and transportationprocess; the dynamic dictionary module realizes automatic update of compression and decompression dictionary, thus being conductive to improving the compression ratio and maintaining the stability ofthe system; and the data decoding module implements the process of decoding and restoring the compressed data stored in the tag into material data. The RFID tag data compression method for a discretemanufacturing workshop not only realizes compression and storage of the material data, but also can solve the data communication problem caused by the independent operation of the system in some discrete manufacturing workshops. The RFID tag data compression method for a discrete manufacturing workshop has low compression ratio and high compression and decompression efficiency, and has a very highpromotion value in application of RFID in the discrete manufacturing workshop.
Description
technical field [0001] The invention belongs to the technical field of data compression, and in particular relates to an RFID tag data compression method for discrete manufacturing workshops, which is used for compressing and storing material data in discrete manufacturing workshops into RFID tags. Background technique [0002] Discrete manufacturing workshops have the characteristics of many types of products, complex production processes, and long production cycles. Higher requirements are put forward for the management and control efficiency of discrete manufacturing processes. High real-time and reliable information collection methods play an important role. As a non-contact automatic identification technology, RFID has the advantages of large data storage capacity, long service life, high identification accuracy, good anti-interference, and can dynamically read and write multiple tags. It is especially suitable for applications with high real-time and reliability. Discr...
