Research On Data Acquisition And Storage Of Submerged Buoy System

Data acquisition plays an important part in the field of underwater acoustic technology.With an increasingly deep research on the ocean, submerged buoy systems are getting moreand more widely used. In recent years, with the spring up of vector hydrophones, the researchof the submerged buoys based on vector sensors becomes deeper and wider. A submergedbuoy system based on vector hydrophone and the storage of data are investigated in detailedin this paper, from the point of view of the project applications.A complete set of submerged buoy system comprises of core circuit, peripheral supportequipment and an interface program for computer. The system of the core circuit containspreconditioning circuits and digital circuits: the former pretreats the output signal byamplification and filtering, and the latter is responsible for data collection, storage andtransmission while the system records the information of time and layout of vectorhydrophone. The equipment of the peripheral support ensures the dipping of the system andstable operating environment for the core circuit. The PC software realized the function ofcontrol of the circuit and the requirement of the GPS information.This thesis can be divided into three parts: system design, system implementation andexperiment test. Firstly, according to the system function and norm desired, design ideas anddesign scheme are proposed; secondly, the specific realization is put forward; finally, theindex of the submerged buoy system is test via experiments.Through the system performance in the test and analysis of experimental results, it isknown that the submerged buoy systems for data acquisition and storage designed in thispaper can basically satisfy the design specifications and achieve the expected goals.
