In view of the problem that single sensor can not accurately determine whether the risk or not in common gas monitoring system, a multi-sensor fuzzy information fusion monitoring method is provided based on fuzzy set theory. This method makes obfuscation for the information obtained by multiple sensors of monitoring equipment and then makes fusion to obtain accurate state estimation of equipment....
A novel alarming assessment model of coalmine gas is presented in this paper. Based on the information fusion technique of multi-sensor, we introduce the thought of variable fuzzy set to assess complicated and risk coalmine gas. Through information fusion we can get more effective and reliable data about coalmine gas. The method for variable fuzzy set theory can reasonable identify the relative membership...
A multisensor system in coal mine is composed of a dozen even dozens of gas monitoring sensors. There is coupling in sensors of the gas monitoring systems. And it is interesting. The paper focuses on two topics about correlation analysis for multisensor system. One is about multisensor correlation analysis. Correlation information entropy and condition number of matrix were used. The other is about...
The mining slope safety is one of the important problems should be solved in all mining problems. Mining landslide which caused by slope deformation often produces great influence on mining project construction and production, even result in the loss of human lives. The paper links with practical circs of one larger-scale opencast mine, discussed the system of GPS slope safety monitor of opencast...
