Abstract


Underwater acoustic data acquisition system underwater acoustic experiments an important method of obtaining data , it has a small background interference , observation records a long time , etc. . A complete data acquisition system should contain the following features : the hydrophone signal pre- conditioning ; compass and GPS communication ; able to achieve the hydrophone signal acquisition and storage capabilities ; with wireless communication capabilities and power management features . This thesis, the data acquisition system for underwater acoustic data acquisition is in line with the vector hydrophone . And a single vector hydrophone has the advantages of small size , light weight , laying simple , suitable for a variety of underwater acoustic experimental requirements . This thesis is divided into a part of hardware circuit and software part and experimental verification . Papers hardware part PC/104 computer as the core of the acquisition , its advantage lies in a powerful acquisition system developed within a very short period of time , and greatly reduce development cost and difficulty of development , and facilitate the future expansion and upgrade . PC/104 computer with multi-channel analog filtering , data acquisition card to achieve a the hydrophone signal conditioning and acquisition work . Software part based MFC of VC prepared , and focuses on the core idea of software programming , the use of multi-threading technology to improve software performance . In addition, data transmission and power management of the wireless communication module and collector . In order to verify that the system functions indicators laboratory system functional tests and field trials , basically meet the system indicators and targets .
