Acoustic wave tide measurement instrument and measurement method

Abstract

The invention discloses an acoustic wave tide measurement instrument. The acoustic wave tide measurement instrument comprises an underwater part and an overground part, wherein the underwater part comprises an underwater bracket and a watertight case mounted on the underwater bracket, and the overground part is an upper computer; an acoustic energy converter array is distributed at the top of thewatertight case, and a pressure sensor and a temperature sensor are mounted on the side surface of the acoustic energy converter array and on the surface of the watertight case; and a signal processing board and a battery are arranged in the watertight case, and a three-dimensional electronic compass and a memory card are mounted on the signal processing board. The invention simultaneously discloses an acoustic wave tide measurement method. The measurement method comprises the following steps: data collection, data processing and calculation of high-low tides and wave characteristic values. The acoustic wave tide measurement instrument can be used for simultaneously measuring wave height, wave period, wave direction and tide level and has the functions of automatically finishing the collection, processing, storage, formulation and submitting of files, remote transmission and user service in an all-weather manner, is strong in universality, provides measurement data with high accuracy and is applicable to occasions of coastal ocean stations, wharfs, large-scale ocean engineering and the like.

Description

technical field [0001] The invention belongs to the field of offshore ocean wave and tide level observation systems, and in particular relates to an acoustic wave and tide measuring instrument and a measuring method. Background technique [0002] The study of ocean waves has always been an important research content in the field of ocean engineering. Accurate and real-time ocean wave measurement is an important requirement for ship navigation, ocean engineering, ocean forecasting, disaster prevention and mitigation, and navigation safety. [0003] Waves are one of the important contents of physical oceanography research. Wave measurement methods can be divided into: direct measurement method and remote sensing method. The direct measurement method generally places the measuring instrument directly in the measurement water area to directly measure the wave; the remote sensing method means that the instrument remotely measures the wave information through microwave, electroma...

AI Technical Summary

Problems solved by technology

The main disadvantages of Langlong are as follows: (1) It uses an array of current measuring points close to the water surface to estimate the wave direction. The inversion of currents requires accurate wave-induced current extraction, which is very difficult

(2) The measurement parameters of Longlong have no tide level parameters
