Wave detection system

Abstract

The invention provides a wave detection system including a data processor, a data collector, a wave-height gauge, and a flow velocity instrument, one end of the wave-height gauge leads out of the liquid surface and the other end of the wave-height gauge is immersed into the fluid, The flow velocity instrument is arranged in the fluid, the wave-height gauge and the flow velocity instrument are arranged on the same section, the data collector acquires the signals fed back by the wave-height gauge, and the flow velocity instrument and transmits the signals to the data processor. The system is high in precision, wide in application, and flexible in instrument arrangement, can obtain the time domain process curve of the incident wave and the reflection wave, is suitable for regular wave and irregular wave, and effectively improves the accuracy of a wave model test.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a wave detection system. Background technique [0002] In marine engineering, waves will be reflected on hydraulic structures, and it is of great significance to accurately obtain the characteristic parameters of reflected waves for the design of marine engineering structures. At the same time, in the ocean engineering physical model test, the reflected wave will undergo secondary reflection on the wave-making plate, and the elimination of the secondary reflection also requires separation of the incoming reflected wave. The common separation methods of incident and reflected waves include two-point method and three-point method based on wave height measurement. These two methods are separated by recording the water surface process of different sections of the tank. There are several shortcomings in these two methods. The applicable frequency band limit is not stron...

Problems solved by technology

These two methods are separated by recording the water surface process of different sections of the tank. There are several shortcomings in these two methods. Applicable frequency band limitation, the applicability is not strong for gravity waves with longer periods; although the three-point method is applicable to a wider frequency range, it still cannot obtain the water surface process of incident waves and reflected waves, and it cannot accurately perform wave statistical analysis
