Abstract:
In a new life style, elders can stay in multiple places instead of a single place. The new life style has two features, i.e. multiple scenarios and changes of status of elders, which lead challenges to traditional elder monitoring systems in cooperation and flexibility. This paper presents a new cyber-physical system for elders monitoring, which is divided to two layers, a sub-system layer and a global service layer. Active databases with real-time event-condition-action rule reasoning system are used as core components in sub-systems and the global service to detect risks and cooperate with other systems actively, intelligently, and at real-time. Structure of an ECA rule reasoning system is flexible, in which ECA rules can be adjusted on-the-fly. We discuss some properties in the cyber-physical system, including cooperation among sub-systems, flexibility and real-time property. At last, we present a case study to validate our works.
