摘　　要：为减小移动水质监测平台定位中测距误差对定位精度的影响,提出一种改进的定位方法。利用NanoPAN5375无线通信测距模块对平台进行定位检测,设计两点测距定位算法和误差修正算法,通过测距误差指纹库补偿测距值,根据面积比重得到修正的测距值,求解出目标点坐标。实验结果表明,该方法可满足移动水质监测平台中无线定位的精度要求。To resolve the contradiction between positioning accuracy and positioning errors of the existing position methods,this paper proposes an improved localization method.The NanoPAN5375 wireless communication and ranging module is used for platform localization,two points ranging position algorithm and a new error correction algorithm are adopted.The fingerprint database of ranging error is compensated for the value of range,the value of range is corrected through the proportion of area,and the coordinate of the target is solved.Experimental result shows that this method can meet the wireless localization accuracy demand of moving water quality monitoring platform.
