摘要
为实现综掘工作面无人化作业,提出了一种基于UWB测距技术的掘进机位姿检测方法;分析了TOA定位方法的误差模型,设计了基于UWB信号的TW-TOF测距实验。实验在3个场地进行,分别用以验证信号时延、环境变化、测距范围对系统的精度影响,为系统定位优化算法提供了理论基础。
To realize unmanned operation in fully mechanized working face, one kind of pose detection method of roadheader based on UWB ranging technique was proposed. Analyzed the error model of TOA positioning method, designed TW-TOF ranging experiment based UWB signal. Conducted experiments at three sites in order to verify the accuracy ranging impact on the system including signal delay, environmental change and range, which provides a theoretical basis of optimization positioning algorithm of the system.
