Research on the early warning technology of the mine safety based on wireless sensor networks

According to the study of the quantitative analysis on the major hazards of the entity and virtual body in the mine production system, the early warning method of the mine safety production with the mixed-mode of the active and passive way is presented based on wireless sensor networks. In which, applying the ZigBee2007/PRO protocol stack, wireless sensor microcontroller technology and the GIS positioning of wireless sensor network technology complete the dangerous source data collection such as the environmental parameters of the operation area, the operation parameters of production, and the threshold alarms. The early warning method is the active and passive safety warning system having the comprehensive treatment function of the initiative warning of the mine production safety, event location, coordination of data query and auxiliary accident treatment decisions through the node sensor design, efficient data frame, active and passive early-warning algorithm.
