Event-driven, service-oriented IoT service provision system and its working method

Abstract

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.

Description

technical field [0001] The present invention relates to a technology for providing Internet of Things (IOT) services, more precisely, relates to an event-driven, service-oriented Internet of Things service providing system and a working method thereof, and belongs to the technical field of Internet of Things. Background technique [0002] With the rapid development of embedded computing and new sensor technology, the goal of information and communication technology has developed from the stage of connecting anyone to achieve communication at any time and any place to the current stage where it can be realized by anyone at any time and any place. The stage of connecting and completing interactive communication with objects located in any place. People hope that the virtual world formed by computing facilities and the real physical world will be more closely linked together, so that computing devices can be seamlessly integrated into people's work and life, and through real-ti...

AI Technical Summary

Problems solved by technology

[0009] "Internet of Things Service System" (Chinese Patent Application No. 201110101715.2), this patent application has the following deficiencies: 1. This patent application mainly focuses on transmitting data information to a server connected to the Internet through a wired or wireless network through various sensor units , it can be seen that the Internet of Things service system is a tightly coupled and closed service provision mode, that is, the sensor network collects relevant sensing information and stores it in a centralized server or database, and the sensing data is distributed among multiple heterogeneous services. Sharing and distribution in the system is difficult to solve

Therefore, this service provision mode greatly limits the flexibility and scalability of the system, and is not suitable for the construction of large-scale distributed and complex IoT service systems

2. The Internet of Things service system of the patent application cannot handle the association and aggregation of large-scale and complex events. Therefore, it cannot form high-level contextual cognition, and it is difficult to support smarter services

3. The service system of the patent application is only a relatively simple data acquisition and collection IoT service system, which cannot support the IoT application requirements for related complex business processing based on the collected data

However, this patent application also has the following deficiencies: 1. The system of this patent application mainly focuses on providing open interfaces for enterprises for secondary development; it does not solve the sharing and distribution of large-scale sensing data in multiple heterogeneous service systems

2. The system is basically a centralized IoT service provision platform. Therefore, this service provision mode limits the flexibility and scalability of the system, and is not suitable for the construction of large-scale distributed and complex IoT service systems
