摘要
随着无线通信技术的进步,超宽带(UWB)技术从缩减硬件成本及定位精度的提升都有了大幅的进步,因此其在定位系统中的使用越来越多。通过研究适用于在井下巷道环境的高精度定位方法,研制出了一套适用于井下环境的超宽带无线车辆定位系统。试验结果显示,该系统定位精度高,对进一步实现井下的车辆无人自主导航具有非常大的支撑作用。
Depending on the development of wireless communication technology, Ultra Wide Band （UWB） technology has been significantly progressed in the reduction of hardware cost and the improvement of the positioning accuracy, so it is increasingly used in positioning systems. The research in high precision positioning method of underground tunnel is undertaken. A wireless vehicle positioning system is developed based on ultra widehand technology. The experimental results show that the system positioning localization is very accurate, which will take a large supporting role to realize the autonomous navigation in underground unmanned vehicle.
