地下综采面超宽带自组网人员定位系统

UWB ad hoc network personnel positioning system for underground comprehensive coal mining face

针对地下综采面人员低精度甚至难定位问题,该文提出了地下综采面超宽带自组网人员定位系统及方法。该方法简单、系统易于实现,只需3个已知超宽带(UWB)基站坐标即可实现综采面所有UWB基站坐标传递和高精度人员定位。在一端确立3个已知坐标的综采面内布设UWB基站,然后UWB自组网解算整个综采面所有UWB基站坐标,最后通过UWB定位算法获取人员高精度坐标。实验表明,该方法能有效实现综采面人员定位,定位精度达0.08m,点位精度小于0.1m的精度可靠性为82%。

Aiming at the problem of low precision and even difficult positioning of underground fully mechanized mining face,the system and method of ultra wide band(UWB)ad hoc network personnel positioning in underground fully mechanized mining face were proposed.The method is simple and the system is easy to implement.Only three known UWB base station coordinates can realize the coordinate transmission and highprecision personnel positioning of all UWB base stations in the fully mechanized mining face.UWB base stations are arranged in the fully mechanized mining plane with three known coordinates at one end.Then UWB ad hoc network solves the coordinates of all UWB base stations in the entire fully mechanized mining face.Finally,the UWB positioning algorithm can obtain the high-precision coordinates of the personnel.Experiments showed that the method could effectively realize the positioning of the fully mechanized mining face,the positioning accuracy was 0.08 meters,and the accuracy of the point accuracy was less than 0.1 meters was 82%.
