Abstract
|
Intelligent community makes use of sensor network, Internet, mobile Internet,3G networks and the associated terminal to integrate all kinds of public information application system in the community with the property owner home application system. Its purpose is providing better intelligent services for residents. Intelligent community process the information which mainly be collected by kinds of sensors and then feedback to the user timely by the Internet of things technology, so that it can realize no matter when and where to provide intelligent services for users. This requires the devices on intelligent community should be capable of context awareness, so intelligent community service system is actually a context awareness service system.Context collection and context modeling are the two important stages of the context awareness system. Context collection mainly collects context information by the sensor nodes in the context aware service system. Context modeling can validate the existing context aware system to find the potential deficiencies and optimize the system.This paper studies the intelligent community context awareness service system, and mainly in view of two major context awareness system in intelligent community, empty nest elder monitoring and security system and intelligent community security and defense system. In the stage of the context collection, the paper collect the context on the empty nesters security system based on the optimal stopping theory to get the better quality context information. In the stage of the context model, the paper uses Petri Net to model the intelligent community security and defense system and simulation analysis the system.
