| 摘 要： | 针对现有井下定位系统大多只能提供区域性定位功能,无法为人员或设备提供精准、实时的位置信息的问题,提出了基于CSS技术的井下精确定位系统设计方案。该系统利用SDS-TWR定位算法和定位管理协议,在得到高定位精度的同时,不需要进行系统的时钟同步,增强了系统的可实现性和稳定性。井下测试结果表明,该系统可实现井下设备和人员的高精度定位,定位精度达到3m以内,最远传输距离达到350m。

| Abstract: | Most underground positioning systems can only provide regional positioning function and are unable to provide accurate real-time location information for personnels or equipments,a design scheme of underground precise positioning system based on CSS technology was proposed.The system uses SDS-TWR localization algorithm and positioning management protocol to get high positioning accuracy.Meanwhile,it doesn't need to do clock synchronization,which enhances realizability and stability of the system.The testing results show that the system realizes high-precision positioning for underground equipments and personnels,which positioning accuracy is less than 3 m and the farthest transmission distance is 350m. |
