Sensor networks-based monitoring and fuzzy information fusion System for underground Gas disaster

In view of the shortcoming of traditional underground gas monitoring system, a new kind of wireless monitoring system was designed. Furthermore, in order to solve the problem of the gas explosion limit reducing once the coal dust involved, the explosion parameters were detected by multi-sensor and the information of dust, gas concentration and temperature from sensors were carried on fuzzy processing to be fused based on fuzzy information and fusion theory. The system can finish fusion computing and decision-making of various system parameters to realize the early prediction for mine explosion successfully. The experimental results indicate that the discerning accuracy and reliability of mine explosion detection system is greatly increased based on fuzzy information and data fusion. It is concluded that the system is of great significance to coal mine production safety.
