Problems solved by technology

[0004] The present invention mainly aims at the problem of low efficiency of detecting complex events in massive out-of-order data streams of the manufacturing Internet of Things, and proposes a complex event detection method for massive out-of-order data streams in the manufacturing Internet of Things. The method mainly uses ENFA (Extended Nondeterministic Finite Automaton) to detect The events in the massive out-of-order data stream are selected, and the storage relationship of the hash table structure is used to process the events in the massive out-of-order data stream, so as to realize the complex event detection in the massive out-of-order data stream and improve the current massive out-of-order data stream The complex event detection method in the data stream expands the existing complex event detection technology and improves the efficiency of complex event detection in massive out-of-order data streams in the manufacturing industry

Embodiment 1

[0028] This embodiment describes in detail the specific matching process of a complex event detection method for massive out-of-order data streams in the manufacturing Internet of Things. In this example, we use the data generator module to generate out-of-order data streams, and control the number of event types generated by the parameters of the data generator module, the probability distribution of data streams, etc., to meet the needs of the experiment. The experimental tool of this embodiment is: Visual C ++ 6.0, and the test index is: two aspects of event search time and throughput in data streams with different scales of disordered order and different proportions of disordered order, the comparison method of this embodiment is: SASE+stack +sort method and SASE+buffer+sort method.

Abstract

The invention discloses a detection method for complex events in mass disordered data streams of Internet of Things Manufacturing, and aims at solving the problem of low efficiency on detecting the events in mass disordered data streams in the Internet of Things Manufacturing. The method is characterized in that ENFA (Extended Nondeterministic Finite Automaton) is utilized for selecting events in mass disordered data streams, and the storage relationship of a hash table structure is utilized to handle events in the mass disordered data streams, so as to realize the detection of the complex events in mass disordered data streams. The method has the advantages that the existing automaton-based complex event mode detection method is improved, the existing complex event detection technology is expanded to be able to efficiently detect the complex events in the mass disordered data streams, and therefore, the detection efficiency is raised.
