走航式ADCP数据成果转换技术研究

Research on the vessel-mounted ADCP data result conversion technology

提出一种走航式ADCP数据的转换方案,通过开发软件可自动提取走航式ADCP原始观测数据,经系统过滤或人工选择后,按测回结果的平均值误差不超过±5%的规范要求,自动判断流量测验成果中测次的有效性。同时,根据GB 50179—2015《河流流量测验规范》自动筛选有效测次结果,并写入多普勒流速仪流量测验记载表,有效解决走航式ADCP测验成果与平台系统的衔接问题。

A conversion scheme of vessel-mounted ADCP data is proposed.The original observation data of vessel mounted ADCP can be automatically extracted through the developed software.After system filtering or manual selection,the validity of the measurement times in the flow measurement results can be automatically judged according to the standard requirement that the average error of the measured results does not exceed±5%.At the same time,effective measurement results are automatically screened according to the GB 50179-2015 Code for river flow measurement,and written into the Doppler current meter flow measurement record table,effectively solving the problem of connection between the vessel-mounted ADCP test results and the platform system.
