Embodiment 1

[0060] A multi-reasoning engine fusion context perception system includes: a sensor module connected to a context perception system management module, a primary context extraction module, a multi-engine reasoning fusion module and a context application module.

[0061]The sensor module is used to collect original context information collected from various sensors, and transmit the original context information to the primary context extraction module, while the sensor module dynamically manages sensor resources; the primary context extraction module receives , processing the original context information, generating primary context information, and storing and distributing it; the multi-engine reasoning fusion module queries the primary context information from the upper primary context extraction module, and the multi-engine reasoning fusion module Utilize the primary context information to generate high-level context information through multi-engine reasoning and fusion, and st...

Embodiment 2

[0076] As described in Embodiment 1, the working method of multi-inference engine fusion context awareness system, the specific steps include:

[0077] (1) Initialization

[0078] The preset information unit extracts the initial setting information of the user and the system administrator, and stores the initial setting information in the policy database unit; the policy database unit sends the setting information to the fusion engine management unit, the reasoning engine management unit, the context modeling management unit, the sensor management unit; the fusion engine management unit, the inference engine management unit, the context modeling management unit, and the sensor management unit initialize configuration according to setting information, Set their own initial working mode and parameters;

[0079] (2) Context service discovery

[0080] The context-aware service management unit listens to information acquired by the perception system, monitors user behavior / status...

Abstract

A multi inference engine-fused context sensing system frame comprises a sensor module connected with a context sensing system managing module, a primary context extracting module, a multi-engine inference fusing module and a context applying module. A primary context storing/distributing managing unit and a high class context storing/distributing managing unit are added into the context sensing system, and manage a context information query requirement in a unified manner, and distribute context information for corresponding units, thus reducing the coupling degree among the primary context extracting module, the multi-engine inference fusing module and the context applying module, facilitating the unified scheduling and managing of the context information, saving system load and overhead and enabling the whole context sensing system to be more flexible and intelligent.

Description

technical field [0001] The invention relates to a multi-reasoning engine fusion context awareness system and a working method thereof, belonging to the technical field of pervasive computing. Background technique [0002] With the development of embedded computing technology and sensor technology, as well as the popularization of wireless communication and Internet, intelligent computing services are profoundly changing the whole world. People's expectations for intelligent systems are increasing day by day, and the era of ubiquitous intelligent computing is coming. This "everywhere, everywhere" intelligent computing service method is called ubiquitous computing. Ubiquitous computing organically combines the physical space of people's life with the information space of the virtual world, which will fundamentally change people's way of life. In the space of ubiquitous computing, information access and intelligent computing services will go deep into every corner, and people...
