Problems solved by technology

[0011] The purpose of the present invention is to solve the deficiencies of the existing methods, and propose a distributed ALE architecture, through the division of subtasks, the distribution of label information, and make full use of distributed resources for parallel computing, which solves the problem of excessive load and maintains It ensures the consistency of the report, so that it is transparent to the application layer

Embodiment Construction

[0055] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] attached image 3 The overall architecture of RFID middleware based on distributed ALE is shown. The modules included in the framework are Global-ALE, Sub-ALE, and Connection Pool. details as follows:

[0057] Global-ALE is responsible for responding to the request of the application layer and coordinating each Sub-ALE.

[0058] The Global-ALE can accept the input of the business rules of the application layer, and synchronize these business rules to each Sub-ALE. These business rules include filtering tag patterns, grouping tag patterns, how often to get reports, and defining report formats, among others. Since the basis for processing label information is business rules, and the business rules of each Sub-ALE are synchronized, it lays the foundation for the consistency of reports.

[0059] The application layer can ...

Abstract

The invention provides an RFID middleware based on distributed ALE, which comprises a Global-ALE module, a Sub-ALE module and a connection pool module which are sequentially connected from top to bottom, wherein the Global-ALE module is connected with an application service logic layer in an upward direction; the connection pool module is connected with a reading tag layer in a downward direction; and the Sub-ALE module comprises a plurality of Sub-ALEs, each of which serves the ALE function, and the Sub-ALE has the mapping relationship with each other, that is, the RFID middleware adopts thesame service rules. The RFID middleware adopts the distributed ALE system structure, makes full use of the distributed resources through the sub-mission distribution and the tag information distribution, and well solve the problem of the excessive load, and meanwhile, the RFID middleware keeps the consistency of a report, thereby realizing the transparent application layer.

Description

technical field [0001] The invention belongs to the technical field of RFID middleware, and in particular provides distributed ALE-based RFID middleware. 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. 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. [0003] 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 function of RFID middleware: Collect / Filter. ...
