Embodiment Construction
[0050] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0051] Such as figure 1 As shown, the present invention provides a multi-source information fusion early warning system for the degree of coal spontaneous combustion hazard. The system includes three information fusion layers: parallel distributed detection data layer, information feedback fusion feature layer, and multi-source information intelligent decision-making layer.
[0052] Parallel distributed detection data layer, using the same type of sensors to collect information in a distributed manner, jointly observe the local characteristics of coal spontaneous combustion, and make local alarm decisions based on the coal spontaneous combustion index gas concentration threshold judgment standard, and the ambient temperature sensor makes a large-scale goaf Screening of high temperature early warning points, and the original information is transmitt...
