Problems solved by technology

[0004] At present, the application of complex event processing technology in the field of RFID is usually based on the processing engine, but the current open source complex event processing engine does not provide a distributed solution, which makes the scalability not very good when processing massive RFID data in real time
The distributed real-time computing framework can solve the scalability problem of real-time processing of massive data, but it does not provide specific business logic implementation. Currently mature distributed real-time computing frameworks include S4, Storm, Puma, etc.

Abstract

The invention discloses an RFID oriented complicated event rule dynamic scheduling and data recovery method. Dynamic scheduling of complicated event rules indicates that in a process of processing continuous RFID atom events by a system, the rules can added or deleted dynamically without stopping an application, and the rules are finally scheduled to the suitable processing nodes for addition or deletion. Automatic recovery for rule data indicates that after a fault occurs to a node, automatic reboot can be carried out, an Esper engine can be instantiated again, and the rule data before the fault can be loaded. According to the method, the throughput and the stability of an RFID oriented complicated event processing system in a distributed environment can be improved.

Description

Technical field [0001] The invention relates to RFID, complex event processing, and distributed real-time computing, and particularly relates to the design and implementation of a dynamic scheduling method of complex event rules and a method for automatically recovering rule data. Background technique [0002] RFID (Radio Frequency Identification) technology is currently one of the more mature solutions in the data collection technology of the Internet of Things, and its application range covers manufacturing, logistics, medical, transportation, retail, defense and other industries. In the field of logistics supply chain, as the cost of RFID tags decreases, RFID technology is increasingly used in all aspects of production, transportation, inventory management, and retail. In the RFID application environment, a single reader can generate 200 to 400 pieces of data per second. With the promotion and application of RFID technology, massive amounts of RFID data will be generated in th...
