Research On Fizzy Recognization Of Danger Position And Method To Voive Escape Navigation Under The Underground Coordination Mechanism

Coal mine safety production has been a concern,how to ensure the miners ' personal safety and improve the success rate of the miners 'escape and self-help is always the research focus in the field of coal mine safety.At present,whether the traditional mine or the highly intelligent modern mine,the danger data mainly originates from the downhole sensor identification and the manager to report,the danger information obtains the process lacks the common miner and the Emergency Command Center information coordination,then brings the dangerous data source way to be narrow and the subjectivity is stronger and so on.This kind of incomplete and dangerous situation can lead the command center to make an imperfect solution to the miners in the emergency situation.The above reasons lead to the low efficiency of the miners' escape and dredging in the emergency situation.In view of the above problems,this paper proposes a kind of emergency coordination and guidance mechanism between miners and Emergency command center.In this mechanism,in order to determine hidden danger from the voice information submitted by miners,a method based on the analysis of the miners ' voice data is proposed to analyze the danger ambiguity location,so as to enrich the danger discovery way and perfect the dangerous database.At the same time,in order to improve the efficiency of the miners escape and dredge,an intuitive method of voice escape navigation is proposed.The main research work in this paper is as follows:(1)The underground emergency coordination and guidance platform is designed.The working principle of downhole cooperative dredging mechanism and the concrete flow of cooperation between each module of emergency coordination and guidance platform are analyzed in detail.(2)A method of discriminating the fuzzy position of danger in the process of emergency coordination is presented.The Emergency command center converts the collected miners ' voice data into text data,and the text data is processed in Chinese,data is formatted and the fuzzy data is based on priority to complement the congruent operation,and then the hidden danger data in the actual excavation data are combined with the downhole production.Finally,the position of hidden danger is determined according to the relative position of the miner's movement and danger.(3)The design and realization of real-time voice escape navigation for underground personnel.The Emergency command Center analyzes the downhole distress data,combines the downhole environment data,GIS data and the miner's current state data(position,movement State,physiology function,etc.),uses Dijkstra algorithm to calculate the best escape route for the miner in a dynamic and real-time way.The miners obtain their own mobile status by moving the end,combine the best escape line,well GIS data,generate the real-time navigation text,and use the Voice tool--MSC-SDK in the mobile end to broadcast the navigation text in the voice form to realize the real-time voice navigation in the escape.(4)The prototype system of the Downhole emergency coordination platform is realized,and the validity of the hidden danger detection is verified by the simulation experiment under the mechanism of downhole coordination and the fuzzy position discrimination method.At the same time,it also verifies the effectiveness of real-time voice escape navigation method in emergency situations to improve the efficiency of the miners ' escape and self-help.
