In offshore engineering,the wave height parameter is of great engineering significance to the design of offshore buildings,ships and port.When the wave height reaches a few meters,it may cause ship overturning and port dam breakage.Effectively predicting and simulating the wave height is great important to the construction of seaports,the design and protection of offshore equipment,and the safety of offshore staff.The key of wave height measurement is the design of wave height sensor.Therefore,designing the wave height sensor with high precision and real-time transmission is of great engineering practice significance for the simulation of ocean environment and the study of wave impact load.According to the above requirements,the wave height acquisition system was designed.The system had the functions of anti-interference,wireless charging,wireless experimental data transmission and temperature compensation.The design was mainly composed of two parts: a wave height measurement system with wireless data transmission and a wireless charging system.The hardware circuit of the wave height measurement system based on the principle of AC phase-locked amplifier capacitance detection was designed.This circuit design solved the problem of poor wave height measurement accuracy caused by electromagnetic interference and water temperature changes.It had the functions of wireless experimental data transmission and wireless energy reception,and realized continuous real-time high-precision measurement.The hardware circuit design of the system mainly included the design of wave height detection circuit,operational amplifier circuit,phase sensitive detection circuit,temperature compensation circuit,wireless data transmission circuit,wireless energy receiving circuit and voltage stabilization circuit.The wireless charging system adopted radio waves for wireless charging,which realized real-time charging of the wave height measurement system at a long distance.The hardware circuit design of this system mainly included the design of radio frequency oscillation generating circuit and radio frequency power amplifier circuit.The results of experimental showed that the design of wave height measurement system and wireless charging system for wireless data transmission was feasible,the measurement accuracy of the wave height measurement system met the design requirements.In this paper,wireless charging and wireless data transmission are used to realize the precise measurement of wave height.It shortens the cycle of marine physics model experiment and reduces the experimental cost.At the same time,accurate measurement of wave height for offshore physics model experiments is of great scientific significance.
