Online detecting failure of gas sensors in mine wells is an important problem. A key step for solution of the problem is estimating sample values of detected gas sensor, according to sample values of other gas sensors. We propose a scheme based on ISGNN (iteration self-generating neural networks) to estimate gas concentration of coal mines in this paper. First of all, sensors whose correlation information...
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...
