Problems solved by technology

[0005] Existing situational awareness systems often only eliminate one aspect (inconsistency) of uncertainty problems, without considering a comprehensive uncertainty elimination plan; and often use a single elimination algorithm in the elimination of incomplete situational information, This leads to low processing accuracy; in terms of eliminating inconsistencies in situational information, a single source credibility evaluation mechanism is often used to eliminate inconsistencies in original situational information, resulting in low reliability

Embodiment 1

[0085] A context-aware system for uncertainty elimination based on reliability management, such as figure 1 As shown, it includes a situational information collection module, a situational information processing module, a knowledge base module, a situational information response module, a situational information application module, a situational information retrieval / subscription module, a situational information correction module and a user feedback module;

[0086] The situational information acquisition module, the situational information processing module, and the knowledge base module are connected in sequence; the knowledge base module, the situational information application module, the situational information retrieval / subscription module, and the situational information correction The information application modules are connected sequentially, and the user feedback module is respectively connected to the knowledge base module and the situational information application...

Embodiment 2

[0107] The uncertainty elimination based on reliability management described in Embodiment 1 The working method of uncertainty elimination based on reliability management of the situation awareness system, such as figure 2 As shown in the figure, a typical scenario of context-aware computing—smart home is taken as an example. In the smart home, four methods of WIFI, bluetooth, infrared and Zigbee are used to collect location information about people, and the scene information obtained by WIFI, bluetooth, infrared and Zigbee are I WIFI , I 蓝牙 , I 红外 , I Zigbee , including the following steps:

[0108] S01: Collection and modeling of situational information

[0109] Collect the situational information collected by multiple physical sensors, virtual sensors and logical sensors, and model the situational information according to the situational information modeling mode in the knowledge base module. The modeling mode is "situational awareness type + situational awareness info...

Abstract

The present invention relates to a reliability management-based uncertainty elimination scene perception system and a working method thereof. The system comprises a scene information collection module, a scene information processing module, a knowledge library module, a scene response module, a scene information application module, a scene information retrieval or subscription module, a scene information correction module, and a user feedback module. The scene processing module comprises a multi-algorithm incompleteness elimination unit, an algorithm result inconsistency elimination unit, a credibility management unit, a reliability management unit, an information source inconsistency elimination unit, a scene information fusion deduction unit, and an adaptive management unit. Through adoption of the system and method, more reliable scene information can be obtained, and the accuracy, reliability and self-adaptation of the scene perception system are improved remarkably.

Description

technical field [0001] The invention proposes a reliability management-based uncertainty elimination situational awareness system and a working method thereof, which belong to the technical field of situational awareness. Background technique [0002] With the improvement of wireless sensing technology, human-computer interaction technology and intelligent computing technology, situational awareness technology has developed rapidly, and the situational awareness system can be integrated into people's daily life. The situational awareness system is a human-centered computing system, in which each sensor device can automatically sense the situation and the change of the situation, and provide users with services related to the current situation. [0003] Ideal situational information should be accurate, complete and consistent deterministic information, but in actual situational awareness applications, the same situational information can be obtained from different information...
