Research On Ocean Wave Measurement System Based On RTK Technology

With the continuous development of the world economy,human activities at sea are also increasing.In order to better help people grasp the characteristics of the marine environment,further develop and utilize marine resources and improve the ability of marine disaster early warning,we need to constantly strengthen the marine monitoring technology.And obtain the wave parameters with wave measuring system is one of the important direction.Firstly,the wave measurement systems at home and abroad is introduced and summarized.Based on the analysis of their working principles and characteristics,a wave measurement system based on RTK technology is designed.This paper introduces the overall design of the system,analyzes the principle and realization process of RTK technology,and gives a detailed description of the system's hardware and software design,including the circuit design of the microprocessor module,the RTK high precision positioning board module,the storage module and the data transmission module,and the software design of each part in the system.Besides,in the traditional wave buoy data processing algorithm,the highly variable sequence of buoys is directly treated as the wave height change sequence of the fixed point for processing and analysis.To solve this problem,combined with the characteristics of the measured data,a new geometric optimization algorithm is proposed to process the buoy data,so as to get a more accurate wave height change sequence of the fixed point.In this paper,the principle of the algorithm is introduced in detail,and the simulation test is carried out to verify the validity of the algorithm.The debugging and experimental results of the system show that the system achieves the purpose of wave measurement,and its structure is reasonable.Its accuracy also meets the requirements,and it has good reliability and stability.
