Problems solved by technology

Regardless of the application scenario, whether or not an appropriate algorithm can be selected for data processing determines the effectiveness of the entire data fusion system. In an increasingly complex system structure, when faced with various data from different sources and with different characteristics, often only The use of specific algorithms often cannot meet the requirements of data fusion systems
The lack of "flexibility" in the system is not conducive to the expansion and wide application of the system
[0005] To sum up, the current data fusion technology still lacks a unified framework and cannot cope with complex and changeable application scenarios. The algorithms used cannot achieve the best results when faced with data from different sources and with different characteristics.

Abstract

The present invention relates to a data fusion system based on a data evaluation and system coordination module and its working method. The data fusion system includes an information collection module, an information processing module, an application and feedback module, a data evaluation and system coordination module, and a knowledge base modules and database modules. The data analysis and algorithm selection mechanism in the data evaluation and system coordination module analyzes the collected data twice successively through feedback information from the data itself and experts or users, so as to determine the algorithm suitable for the current data fusion system, and coordinate all aspects of the system. module resources. The introduction of data evaluation and system coordination modules enables the system to "tailor" the data and select an appropriate processing method when dealing with specific data on the premise of meeting user needs, ensuring the rationality of algorithm selection and the integration of the system. The versatility also makes the entire data fusion process more flexible and efficient, and the results more reliable.

Description

technical field [0001] The invention relates to a data fusion system based on a data evaluation and system coordination module and a working method thereof, belonging to the technical field of data fusion. Background technique [0002] Data fusion refers to the analysis, synthesis and calculation of observation information from multiple sensors or sources, so as to obtain more accurate and complete results than a single data source. It was originally used in the military field, and has gradually been widely used in various fields such as industrial manufacturing, smart home, and medical diagnosis. [0003] Most of the information to be processed in data fusion comes from different aspects of the same target. For example, when judging the status of human body signs, by analyzing and computing the body temperature, blood pressure, pulse, heart rate and other sign information collected by multi-source sensors, using data Fusion algorithm and decision rules get the final judgme...
