Problems solved by technology

[0008] 3. If there is a correlation between the ECSpecs of the overloaded middleware, all ECSpecs need to be moved to the target middleware, which may cause overload of the target middleware
The disadvantage of this solution is that all middleware must save the same set of ECSpec files

Embodiment Construction

[0023] The detailed steps of the present invention are as follows:

[0024] 1 Receive and distribute the tag data from the reader.

[0025] A load balancing management module is added to each middleware, which is responsible for receiving and distributing tag data corresponding to the middleware reader. The load balancing management module sends the label data to be processed by this middleware to the processing cache of this middleware, and sends the label data to be transferred to the transit cache, waiting for other middleware to take it away.

[0026] 2. Monitor whether the middleware is overloaded. When a certain middleware is overloaded, determine the equivalent load of the middleware, and determine the reader / writer that needs to be moved.

[0027] The load of the middleware is mainly determined by two factors: ECSpec and the tag data obtained by the reader. And there is a corresponding relationship between ECSpec and label data. Considering that a tag data correspon...

Abstract

The present invention provides a dynamic load equilibria method for radio frequency identifying middleware. The method includes steps as follows: if a local middleware over-load, searching a reader-writer with a label collecting rate nearest to the over-load from the reader-writer having logical relationship with the local middleware, and keeping a physical connection with the local middleware constant, the logical connection updating to other light-load middleware, transferring or copying the ECSpec relative the reader-writer to a same light-load middleware. The method needs not change reader-writer physical connection, each middleware only keeps the ECSpec file relative to the reader-writer having logic connection, and can realize dynamic load equilibria among a plurality of RFID middlewares.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification (RFID), in particular to a dynamic load balancing method applied to radio frequency identification middleware. Background technique [0002] Radio Frequency Identification (RFID), as an emerging technology, shows great potential in the field of automatic identification. With the development of RFID technology, the improvement of security, and the decline of the price of RFID tags, more and more enterprises have begun to pay attention to and introduce related applications of RFID technology, so as to improve their competitiveness in the commercial field. As a new branch of software system, RFID middleware promotes the data interaction between automatic identification instruments such as readers and enterprise applications. Identification and tracking based on RFID technology can make product statistics and positioning faster and more accurate. At present in my country, elec...
