The technique of mine gas monitoring based on multi-sensor information fusion

The problem of factors influencing the sensors in a mine gas monitoring system cannot be solved by a single sensor itself. The multi-sensor information fusion technique was put forward to increase the system’s information utilance, precision, dependability and error tolerance. Based on the information source that the mine gas monitoring system has collected, the system’s structure mode was defined, the structure mode was described by the state space method, and the multi-sensor information fusion state space model of the mine gas monitoring system was also built. A fuzzy neural network model for the multi-sensor information fusion was built by adopting the artificial intelligence method.
