This paper proposed a kind of universal event model to express kinds of data gathered by different equipments. Because of limited memory and masses of data,it proposed the structure of event tree to compress and store event instances,and then proposed the method of complex events detection based on shared matching results,which was based on the model of matching tree. Finally,experimental results on sparse data and dense data show that event tree can make limited memory store more event instances and the method of detecting complex events based on shared matching results can improve the efficiency of query effectively.
