水平固定式声学多普勒流速剖面仪研制及工程比测

Development of horizontal fixed acoustic Doppler current profiler and engineering comparison test

阐述了声学多普勒效应的原理并给出了ADCP测流公式;简述了国标中ADCP的测试条件和检测方法;重点介绍了南瑞水电公司NDCP3025H型H-ADCP系统工作原理以及H-ADCP与TRDI走航式ADCP的工程比测情况,并对比测数据进行了分析;结果表明:NDCP3025H型HADCP与走航式ADCP的流速测值具有较好的一致性,测量精度优于国标要求,为H-ADCP的商业化推广和应用奠定了坚实的基础。

In this paper, the principle of acoustic Doppler effect is described, the velocity formula of ADCP is provided, and the test conditions and detection methods for ADCP in national standard are introduced. This paper mainly introduces the H-ADCP working principle of NDCP3025H, as well as the engineering comparison test between the H-ADCP and the vessel-mounted ADCP of TRDI and analyses the comparison data. The results show that the velocity value of the H-ADCP has better consistency with the vessel-mounted ADCP, and the measurement error is better than the national standard, which has established a solid foundation for the commercial promotion and application of the independent H-ADCP.
