摘要
针对煤矿井下一维环境中人员及设备的定位问题,对一维定位理论及应用进行了研究,提出了一维分段定位法,设计了基于无线射频模块的定位系统。定位系统以ATmega1284P微处理器为主控芯片,以nano PAN5375射频模块为核心,采用对称双边双路测距算法(SDS-TWR)实现测距,利用一维分段定位法和卡尔曼滤波算法计算得到最后的定位信息。试验结果表明:系统能够完成实时测距和定位,定位误差可达1 m以内。
Aiming at personnel and equipment locating problem in one-dimensional environment of underground coal mine, we studied one-dimensional positioning theory and application. We propose one-dimensional pieeewise positioning method and designed the positioning system based on radio frequency （RF）module. The system takes ATmega1284P microprocessor as the controller and the nanoPAN5375 as the RF chip, and uses symmetrical double-sided two-way ranging method to achieve real-time ranging, and adopts one-dimensional piecewise positioning method and Kalman filtering algorithm to calculate the final location information. The results indicate that the system can perform real-time ranging and positioning and the positioning error is less than 1 m.
