Lightweight middleware-based networking RFID system and data interaction method

Abstract

The invention discloses a lightweight middleware-based networking RFID system, which comprises at least one middleware computer, at least one management computer and a distributed data transmission management module. The management computer is connected with the middleware computer through a network; each middleware computer is provided with a temporary database system and at least one data extraction module; each management computer is provided with a newly read label temporary database, a main database and an information processing module; the distributed data transmission management module allocates the newly read label data in the temporary database system of the middleware computer as required and transmits the data to the newly read label temporary database of the management computer through the network, and the data is processed by the main database and the information processing module of the management computer. The system is simple in structure, easy to construct and expand, low in cost and suitable for medium-sized and small enterprises; and the data distributed on different computers can be conveniently processed.

Description

technical field [0001] The present invention relates to radio frequency identification (RFID) technology, in particular to a networked RFID system based on lightweight middleware and a data interaction method, which has a simple structure and is easy to construct, is very suitable for small and medium-sized enterprises, and can realize data collection and conversion It is carried out off-site with the data application, and there is a clear identification of responsibilities between the management party and the data collection party, as well as between multiple managers. Background technique [0002] RFID is a non-contact automatic identification technology, which can automatically identify target objects and obtain relevant data through radio frequency signals, without manual intervention, and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient...

AI Technical Summary

Problems solved by technology

In the actual research, the inventor found that many enterprises need to carry out data collection and conversion and data application management in different places, and the existing integrated systems are difficult to meet this application requirement, and these integrated systems still have the following shortcomings :

The database processing of the enterprise management application system itself requires a lot of computing power. Because the database-based middleware needs to obtain all historical data, it adopts the idea of ​​complete records, and continuously filters out label codes that have not appeared recently. It requires a large amount of calculation, so putting the two on the same computer requires high computer hardware, resulting in high cost, which is not a good solution in the existing hardware environment

[0007] 2) It is not convenient for joint development

The middleware currently developed can be used as an independent product, but it is difficult to draw the boundary between the two systems when interfaced with the enterprise management application system, because they are all database management, and cooperation between different units requires a clearer interface label

[0008] 3) It is not convenient for the identification of responsibilities between the data collector and the applicator, as well as between different applicators
