Compound event responding method and system facing to real-time sensing environment

Abstract

The invention discloses a compound event responding method and a system facing to a real-time sensing environment. The method comprises the following steps that: the use of an excess storage space when an event mode to which a state node in an event matching model belongs is judged is avoided by considering the sequence of adding the event mode into an event mode matching model, the priority of the event mode of a business rule which is input currently is obtained by an event mode priority managing module after the business rule and the system response requirement are provided by a user, an event mode queue arranged according to the priority of the event mode is generated and is also submitted to an event detection preprocessing module, the construction of the event mode matching model is finished so as to realize compound event mode matching to obtain system response, and the operation of dispatching is carried out by concurrent execution between the system response of multi-step operations through a dispatching module responding according to an event so as to enhance the real-time property of the system response and meet the timing constraint of system response in a real-time sensing environment; and the invention also discloses the event responding system facing to the real-time sensing environment and corresponding to the method.

Description

technical field [0001] The invention belongs to the technical field of composite event processing (CEP), and in particular relates to a composite event pattern matching method and system that meet the real-time requirements of composite event processing system responses in a real-time sensing environment. Background technique [0002] In existing real-time systems, the system not only requires the logical correctness of data processing, but also requires the completion of data processing tasks within a limited time. With the increase of data, while ensuring the accuracy of data query and processing, timing constraints on the response time of processing data are becoming more and more important. For example, in the RFID system application environment, although the existing RFID event detection technology can realize the timely processing of the event flow, the time for matching each event pattern cannot be effectively constrained and estimated, making the response time of eve...

AI Technical Summary

Problems solved by technology

[0004] At present, the research on the composite event processing system has not considered the construction of the event pattern matching model and the scheduling of the response execution of the event detection system around the response time of the event detection, and the priority of the event pattern has not been considered in the prior art. The impact of the event pattern matching model and the timing constraints (real-time) of the system response

In a real-time environment, the response time requirements of event detection and the priority assignment of event patterns will affect the construction of event pattern matching models and the real-time performance of system responses.
