Embodiment Construction

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

[0033] First, an event-driven RFID data collection, filtering and integration method based on semantic information is provided. 1) Semantic expression of RFID events, establish RFID event semantic model based on RFID event classification and aggregation, such as figure 1 As shown, its model includes: time model, hierarchical model and causal association model; establish a model-based semantic expression hierarchy of RFID events to realize interoperability and integration based on semantic information in the process of RFID event processing; based on RFID event semantic specifications, Divide RFID events into atomic events, simple events and composite events. RFID atomic events are indivisible events that can directly trigger related business processes. Each RFID atomic event provides access information to describe how to access this process. ...

Abstract

The invention discloses a semantic information based RFID complex event processing method. The semantic information based RFID complex event processing method comprises the following steps: abstracting an initial RFID event to be simple events; accurately and efficiently correlating and collecting the RFID streaming data captured by an event source to form an RFID aggregation event required for a service; abstracting the RFID simple events to be a complex event; defining the service events with contextual information and service procedures; conducting service layer data modeling, service synthesis, service compilation and service schedule to the RFID event stream and the service events; defining detection states and state switching conditions of the RFID complex event; converting the system events at the lower layer to be the service events at the higher layer, and establishing the RFID event driving model. The service system binds and captures the service events, conducts fault-tolerance processing and analyzes the service events to obtain the corresponding complex event, so as to analyze the RFID event message, acquire the RFID data meeting the requirements, simplify the service processing procedures, and increase the integrated efficiency of the RFID and the service system.

Description

technical field [0001] The invention relates to RFID middleware, in particular to a semantic information-based RFID complex event processing method. Background technique [0002] In the large-scale deployment of RFID, a large amount of tag data will be generated, most of which are meaningless noise data. In view of the massive data processing requirements in RFID applications, design and implement efficient methods of integrating, filtering and transmitting massive data, so as to prevent enterprises from being overwhelmed by a large amount of data and not getting the benefits of RFID technology is the process of using RFID important issues to be addressed first. In addition, on the basis of data acquisition, it is a huge challenge for the large-scale application of RFID to realize the comprehensive integration of service-oriented RFID technology and enterprise information systems, including RFID data integration, business information and RFID tag data integration. Therefor...
