矿用电机车精确定位及导航系统关键技术研究

Research on Key Technologies for Precise Positioning and Navigation Systems for Mining Motor Vehicles

针对井下电机车的定位技术仅能实现目标的区段定位,无法实时获取行驶电机车精确位置的问题,采用无线及有线通信结合、定位基站和速度传感器互相配合为技术路线设计了一种矿用电机车精确定位及导航系统。该系统可对电机车具体位置、运动轨迹及分布情况等进行实时监测,有效提高定位精度,并建立了一种信号灯自适应控制策略及模型,实现井下电机车运输安全感知全覆盖。

The current positioning technology for underground locomotives can only achieve the segmental positioning of the target,but cannot obtain the precise position of the driving locomotives in real time.Based on this,a mining motorcar positioning and navigation system is designed using a combination of wireless and wired communication,positioning base stations and speed sensors.The system can monitor the specific position,movement trajectory and distribution of the locomotive in real time,efectively improve the positioning accuracy,and establish a signal light adaptive control strategy and model to achieve full coverage of the safety perception of underground locomotive transportation.
