The invention provides a
system for providing services of an event-driven service-oriented
internet of things and a working method of the
system. The
system is composed of a plurality of parts of an
internet of things service system, an access agent, a unified message distribution network based on a publish-subscribe mechanism, a
complex event processing engine, a resource descriptive model base and a
sensor system. The system and the working method solve the problems that an existing system for providing the services of
the internet of things can not process large-scale sensing information in a distributed mode, events in a physical world can not be processed, effective cross-business-domain and cross-organization coordination is difficult to achieve by different enterprise business processes. According to the system, sensing information is effectively distributed in the open and
distributed computing environment, various pieces of sensing information can be conveniently and quickly distributed as required among different
internet of things heterogeneous service systems, event-driven cross-business-domain and cross-organization service dynamic coordination is achieved, time, space and
control flow uncoupled network services are provided, and quick response to change of the physical world can be flexibly and dynamically achieved in real time.
