Design Of Signal Data Sampling And Processing Platform On Ocean Integrated Detecting System

With the rapid development of human society,the demand for natural resources has reached an unprecedented level. The land resource has become more and more stretched.Marine resources will increasingly serve human society. On the other hand,any powerful country is bound to be the powerful country of the marine. Marine interests directly affect the country's comprehensive national strength. Requirement of new international situation is that to China the development of ocean must turn from coastal waters to the sea. Any development to the sea and defending for the marine interest must is based on the exploration of marine information.Under such background, the team developed the Ocean Integrated Detecting System. The system integrates Multi-beam sounding system and the shallow profile detection system. The design is a signal transform and processing platform based on the Ocean Integrated Detecting System.First of all, the thesis analyzes the significance of the ocean integrated detecting system. Then analyzes the present situation of domestic and international development and various forms of signal transform and processing platform. After that analyzes system requirements of .ocean integrated detecting system to signal transform and processing platform.After the analysis, thesis detailed analyzes and discusses the design scheme for every part based on the requirement of function, including scheme design, chip selection, circuit structure, circuit design principle, and system reliability analysis. Completes the schematic design and PCB board design by Altium Designer.The paper further analyzes the time sequence requirements for each module. The control logic of each module is written by Verilog language. Finally realized the basic function of data transmission and processing platform. Hardware platform supported for the corresponding software and control logic of the marine integrated detection system.Finally,the paper tests the function modules of the design. Verify the correctness of the system design, the hardware circuit design of each module, and the control logic.
