Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] refer to figure 1 , the RFID system includes: a number of RFID readers 1, an enterprise management information system 2, and an RFID lightweight middleware 3.

[0034] Several RFID readers 1 can adopt RFID readers with different physical characteristics, such as: RFID readers with different protocols, or RFID readers with different operating frequencies, or RFID readers with different programming environments, or RFID readers from different manufacturers, etc. For example in figure 1 Among them, reader-Al is Alien's RFID reader, reader-Mo is Motorola's RFID reader, and each RFID reader is equipped with at least one antenna. Obviously, RFID readers with the same physical characteristics are also possible.

[0035] The enterprise management information system 2 has: a master database 21 , a commodity management module 22 , and a real-time monitoring module 23 ...

Abstract

The invention relates to an RFID (Radio Frequency Identification Device) lightweight middleware based on a database, comprising a temporary database system, a plurality of reader-writer adapters and at least one trigger. The plurality of reader-writer adapters are all connected with the temporary database system, extract label data detected by the RFID reader writer by invoking the API (Application Programming Interface) function of the RFID reader writer connected with the reader-writer adapters, and write the label data into the temporary database system by invoking the API function of the temporary database system; and a trigger is used for controlling the temporary database system to transmit the updated data to a main database of an enterprise management information system in the specified form. The invention also discloses a method for interacting data of the RFID reader writer with different physical properties and the enterprise management information system based on the middleware. The invention has the advantages of simple integrated processing, convenient reviewing and inquiring, simple interface with the previous information system, convenient encryption and management, and the like.

Description

technical field [0001] The invention relates to radio frequency identification (RFID) technology, in particular to an RFID lightweight middleware implemented based on database function integration. 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. [0003] The RFID system is mainly composed of three parts: tags, readers and middleware between the readers and the enterprise management information system. Since there is no unified standard for RFID at present, the equipment produced by many RFID manufacturers varies greatly. Therefore, the tags used by products from different places are likely to be different, and thei...
