Middleware architecture of Internet of things and SOA architecture-based middleware of Internet of things

Abstract

The invention relates to a middleware architecture of an Internet of things, which comprises a reader layer and an application layer, and is characterized in that: the middleware of the Internet of things comprises an edge layer and an integration layer arranged between the reader layer and the application layer in turn, wherein the edge layer periodically polls a reader through an edge server soas to eliminate repeated operation, executes filtering and equipment management function, simultaneously generates application event management protocol ALE events and transmits the ALE events to theintegration layer; the integration layer receives a plurality of ALE events and combines the ALE events into a workflow; and the workflow is used as one part of a larger service flow to be in contacted application to different systems. In addition, the invention provides SOA architecture-based middleware of the Internet of things. The middleware architecture of the Internet of things is an intermediate program architecture for implementing data transmission, filtering, data format conversion between RFID hardware equipment and an application system, and reduces the difficulty of application development. Therefore, a developer calls through the middleware without directly facing a bottom architecture.

Description

technical field [0001] The invention relates to an Internet of Things middleware and an Internet of Things middleware based on SOA architecture. Background technique [0002] The Internet of Things (EPC system) refers to a broad technical system formed by using the Internet and RFID radio frequency identification technology on the basis of a globally unified coding system. Its goal is to enable enterprises to improve the visibility of capital and ensure the safety and integrity of products through the informatization of the entire supply chain. [0003] The basis for the Internet of Things to realize the informatization of the entire supply chain is to be able to identify all commodities that exist in the global supply chain system, which requires coding each commodity. The Auto-ID Center uses Electronic Product Code (EPC) to realize the identification of each commodity. Since the EPC data in the IoT system is very large, it becomes a difficult problem to transmit and mana...
