A Distributed IoT System based on distributed ontology structure for Task-driven Smart Objects Collaboration

摘要

The object of the present invention is to provide an Internet object system for providing intelligent services. One of the systems of the present invention includes a server and at least one electronic device. The server communicates with at least one electronic device A communication unit; A storage unit capable of storing a plurality of tasks provided for each action of a user and information about a plurality of services that the at least one electronic device can perform; And a control unit that receives status information from the at least one electronic device via the communication unit, determines a task corresponding to a user''s behavior represented by the received status information from among the plurality of tasks, And a processor for causing the first electronic device capable of providing the service corresponding to the task to transmit information on the service, wherein the electronic device comprises: a communication unit capable of communicating with the server; A storage unit capable of storing interaction history information with a user; And a processing unit for providing the service when receiving information on the service from the server. The providing unit provides the service on the basis of the interaction history information with the user stored in the storage unit.According to the present invention, each smart object constituting the IoT collects context information of the surroundings and users as an autonomous distributed object, understands the meaning thereof, and can provide a personalized service to the user on the basis thereof, By providing services on a task-by-task basis, which is a collective concept of services provided, it is possible to provide integrated services to users through collaboration of various smart objects, and overcome the limitations of the centralized IoT system structure.
