Abstract: We designed an intelligent vehicle terminal based on UWB accurate positioning technology, which integrates multiple functions such as precise positioning, 4G/5G wireless communication, video monitoring, data acquisition, voice call and other functions. The intelligent vehicle terminal uses Android platform, takes ARM RK3399 as the control core and UWB communication transceiver chip DW1000 as the precise positioning core, realizing the precise positioning, intelligent scheduling, information collection, safety warning, voice call, human-computer interaction and other functions of the underground vehicle. The test results show that the maximum dynamic positioning error of the vehicle terminal is no more than 7.3 meters, which meets the functional requirements of the coal mine for intelligent auxiliary transportation.
