Research On Signal Centralization Blocking System In Underground Electric Locomotive Transportation Based On Accurate Positioning

In order to improve the efficiency and shipping safety production in coal mine,large mines alleys installed letter sets closed bottom and transportation system.Letter based on the existing set of closed system research,based on the reference of righteousness qiangiu coal group mine the actual transportation situation,proposed and completed based on the accurate location of mine electric locomotive transportation letter sets closed system research.Paper describes the letter sets closed system development present situation at home and abroad,and this system solve the problem,the level of art is to mine a transport system is divided into driving range signal layout,electric switch machine location form letter sets closed system.Decorate in the orbit precise positioning system using topology multiple nodes machine receives the vehicle position information and voice information.Relative to the domestic with the card reader mode determine the relative interval period of electric locomotive,the system innovation of electric locomotive accurately realize point to point.PC monitoring system dispatcher arrange route according to the production requirements,when the locomotive from the interval unlock automatically to realize the automatic scheduling.The research of this paper effectively solves the underground locomotive and electric locomotive communication operation,accurate positioning,and the problem of dispatching automation better achieve the function of locomotive signal focus block,improve the efficiency of locomotive operation,to ensure the security of locomotive running and underground locomotive information-based dispatch has guiding significance.In coal mine has popularization and application value,at the same time there are more development space,so the thesis has theoretical and realistic meaning to study.
