摘要为提高野外测量折射率补偿实时性,研制了1.2km标准基线环境参数测量系统,该系统采用一种硬件分组和软件并行采集方案,将系统传感器数据采集的正确率提高到98%以上,82个传感器完整循环采集一次的时间小于7s。计算出传感器7s采样间隔温度变化量,分析评估折射率补偿结果,为野外标准基线测量提供科学的视角,量化寻找基线理想的测量时段,使延时温差小于0.05℃,高精度测距仪基线测量时的折射率修正误差控制在5×10^-8内。

Abstract：To improve field measurement accuracy, the 1.2km standard baseline an environmental parameters automatic measurement system is developed, and a hardware grouping and software parallel acquisition scheme is adopted. The accuracy rate of sensor data acquisition in the system is more than 98%, and the time of complete cycle acquisition of 82 sensors is less than 7s. Calculate the temperature variation of sensor 7s sampling interval, analyze and evaluate the refractive index compensation results, provide a scientific perspective for field standard baseline measurement, quantify the ideal measurement period of baseline, make the delay temperature difference less than 0.05℃, the refractive index correction error of high precision rangefinder in baseline measurement is controlled within 5×10^-8.

Key words： metrology refractive index correction laser ranging environmental parameter automatic measurement system standard baseline real-time data parallel acquisition
