Application of electrification and digital intelligence of explosion proof vehicles for coal mine auxiliary transportation
In order to improve the intelligentization of auxiliary transportation in coal mines,Shendong Coal Group has built an auxiliary transportation vehicle management system.The modules in the architecture of the auxiliary transportation vehicle management system are introduced.Based on the positioning system for underground personnel and vehicles,the underground 4G or 5G network and roadway base station are used to transmit to each mine ground dispatch room,and then transmitted to the big data center through optical fiber,achieving digital vehicle supervision and making vehicle use and dispatch more convenient.Intelligent technologies were analyzed,such as on-board auxiliary safety driving system,start warning system,intelligent induction automatic shutdown device,neutral start protection device,wireless line of sight remote control for auxiliary transportation vehicles.LiDAR and camera were used to scan and model the roadway,providing a map for unmanned vehicles,and millimeter wave radar and machine vision technology were used to precisely locate the underground auxiliary transportation vehicles,achieving the normalized operation of unmanned driving.The electrification,digital supervision,and intelligentization of auxiliary transportation vehicles in Shendong mining area greatly improved the safety and efficiency of auxiliary transportation,thus to enhance the intelligent mine construction.
