Embedded RFID middleware based on light-weight ALE

Abstract

The invention provides an embedded-type RFID middleware based on lightweight ALE. The embedded-type RFID middleware comprises a lightweight ALE module, a mobile proxy module, a data buffer pool, a middleware configuration management module and an equipment management module, wherein, the lightweight ALE module is connected with an application service logic layer upwards; the mobile proxy model isconnected with an external background RFID middleware or an RFID application system and simultaneously connected with the internal lightweight ALE module; the data buffer pool module is connected with the equipment management module downwards and connected with the lightweight ALE module upwards; the middleware management module is connected with the other four modules respectively; and the equipment management is connected with a physical reader downwards. By arranging the lightweight ALE module, the embedded-type RFID middleware can achieve multi-event handling and user subscription and processing mechanism. Through data buffer pool mechanism, seamless connection between the ALE layer and the equipment management layer and the tag information distribution can be achieved to solve the problem of over-high coupling degree among the modules and to improve the re-configurability and the extensibility of the system, thereby realizing transparent application layer.

Description

technical field [0001] The invention belongs to the technical field of RFID middleware, and in particular provides a design method of embedded RFID middleware based on lightweight ALE. technical background [0002] RFID middleware (Radio Frequency Identification middleware) can automatically identify and collect information and is widely used in various fields. RFID middleware builds a data communication bridge between automatic identification devices (such as RFID readers) and application systems. [0003] The Application Level Event specification defines a set of standard interfaces that RFID middleware should provide to the upper application system, as well as the most basic function of RFID middleware: Collect / Filter. [0004] The Application Level Event specification was officially released by the EPCglobal organization in 2005. It defines a set of standard interfaces that RFID middleware should provide to the upper application system, as well as the most basic functi...
