设计了1种基于UWB精确定位技术，融合精确定位、4G/5G无线通信、视频监控、数据采集、语音通话等多种功能于一体的智能车载终端。智能车载终端采用安卓平台，以ARM RK3399为控制核心，以UWB通信收发芯片DW1000为精确定位核心，实现了井下车辆的精确定位、智能调度、信息采集、安全预警、语音通话、人机交互等功能。测试结果表明：车载终端最大动态定位误差不大于7.3 m，满足煤矿对智能辅助运输的各项功能需求，

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.
