Abstract: The existing auxiliary transportation system in Yangcun Coal Mine has problems such as long transportation battlefront,long lines,multiple transportation modes such as monorail crane transportation,ground rail transportation and others,large number of vehicles and frequent transportation operations,etc.By installing positioning cards on equipment such as mining cars,flatbed trucks,battery electric locomotives,monorail cranes and so on,and with the help of the positioning system of UWB precise positioning,a set of auxiliary transportation monitoring and logistics management system is built.Vehicle positioning adopts UWB precise positioning technology,and an intelligent dispatch and command system for auxiliary transportation with comprehensive and three-dimensional management and control functions such as centralized control of traffic lights,railroad switch control,vehicles position,automatic tracking and management of materials and others is constructed to achieve real-time display of multiple systems on "one platform,one image".In emergency situations,implementing a green channel to directly reach the site in the whole network greatly improves the dispatch efficiency of auxiliary transportation.
