Application of finite automaton in detection of composite event
Fu Ming · Jisuanji gongcheng yu sheji · 2009
Aiming at the problem that early system only provides atomic event detection and cannot detect composite event composed with atomic event,the model of using automaton to detect composite event is presented.A introduction to component and expression of composite event is provided.Detection model of composite event with automaton theory is analyzed,and the process of composite event detection is shown:From event expression to non-decided finite automaton,and from non-decided finite automaton to minimized decided finite automaton,then its realization of decided finite automaton by programming.Through instance illuminates that the model of automaton is one of effective modes to detect composite event.
