| Ocean monitoring is a useful tool which can help us learn and research ocean . Ocean automatic monitoring transducer is the the basal hardware in the technology of marine monitoring. Paper introduces a new ocean instrument---- a data acquisition system based on water wave energy monitoring system ----which has own knowledge property right. And author made numberical simulation and imitation on hydrodynamic reponse of the instrument in its working state.The force condition analyzation of the monitoring system in water can divid into two parts—the part of above water and the part of under water. Based on fluid mechanics theory, paper introduced the influence of the level wave strength on this system in nonlinearity condition, using a analytical method in frequency domain and time domain.The system can present different operating postures on 3D currents effect. And the posture in water has a great influence on the stability of the system. Paper made a detailed numerical analysis in the force of the underwater situation, and built a mathematical model, done the simulation development research, and gave the most direct viewing simulation curve model. Paper use achieved currents data which had been measured in deep water and shallow water, simulation, and performed the virtual state of measurement system working in those conditions, got available movemental curves,and analyzed the relations bewteen the system and the sea condition in which the system can work efficiently.Paper took Matlab as the tool, using a series of theories and the practice research, also coordinated the computer software programming and completed the numberical simulation and simulation work on the vertical section measurement system's power response of sea essential, and presented a scientific preview for the ultimate operation of the system under submarine condition. |
