【摘要】：在分析主流接近探测技术特点和应用现状的基础上,提出基于高精度无线测距和三维定位的井下装备接近探测方法。该方法用对称双向到达时间无线测距方法测量个人标签到探测器的距离,通过三维最小二乘法计算个人标签相对于移动设备的精确坐标,最后通过区域设定和判断得出探测结果。现场试验结果表明,该方法可以实现设备周边360°无死角探测,与RSSI方法和磁场区域标识方法相比,具有定位精度高、响应时间短、配置简便等特点。
[Abstract]:Based on the analysis of the characteristics and application status of mainstream approach detection technology, a new approach detection method for underground equipment based on high precision wireless ranging and 3D positioning is proposed.In this method, the distance between the personal label and the detector is measured by using the symmetrical bidirectional time of arrival wireless ranging method, and the precise coordinates of the personal label relative to the mobile device are calculated by the three-dimensional least square method.Finally, the detection results are obtained by setting and judging the region.The field test results show that the method can detect 360 掳dead angle around the equipment. Compared with the RSSI method and the magnetic field identification method, the method has the advantages of high positioning accuracy, short response time and easy configuration.
