一、ADCP的基本原理ADCP是英文Acoustic Doppler Current Profilers的简称,即声学多普勒流速剖面仪,是利用声学多普勒原理进行研制的,用声波换能器作传感器,声脉冲波通过水体中不均匀分布的泥沙颗粒、浮游生物等反散射体反散射,由换能器接收信号、经测定多普勒频移而测算出流速,从根本上摆脱了机械转动为基础的传感流速仪的测验原理,被认为是流量测验领域的一次革命,是目前世界上最为先进的河流流速流量实时测量设备。ADCP是一种遥测仪器,即ADCP流速测量点不在ADCP所处的位置,并且测验成果可以联机存储,提高了测验的速度。
First, the basic principles of ADCP ADCP is short for English Acoustic Doppler Current Profilers, Acoustic Doppler velocity profiler, is the use of acoustic Doppler principle of the development, the use of acoustic transducers as sensors, acoustic pulse waves through the body of water Inhomogeneous distribution of sediment particles, plankton and other anti-scatter anti-scatter, received by the transducer signal, measured by the Doppler frequency shift and measured the flow rate, basically from the mechanical rotation-based sensing flow meter The test principle, is considered to be a revolution in the field of flow test, is the world’s most advanced real-time measurement of river flow velocity and flow measurement equipment. ADCP is a telemetry instrument where the ADCP flow measurement point is not at the location of the ADCP and test results can be stored online to improve the speed of the test.
