Design Of Underwater Acoustic Buoy Platform Based On OMAP

China has very rich marine resources, and crosses tropical, subtropical and temperatefrom north to south. The long-term supervision of broad waters is very important. Theresearch of Sonobuoys is not only very important to ensure China’s maritime territorialintegrity and also plays an essential role to detect the hydro-geological and mineral resources.The buoy system is very versatile, while the modern sonar buoys research just extendsprofessional functions, the research of common buoy system is rarely to see. This article aimsto design a relatively generic buoy electronic system, in different application conditions, bydynamically changing the buoy system procedures and data processing procedures, withexternal modules, and thus achieve the purpose of use only one system to complete a varietyof buoys task. That is to achieve the purpose of allowing the system to reach a common.Base on the buoy systems classification and development in the world, comprehensiveanalysis of the characteristics and needs of buoys electronic system parameters small size,low power consumption, fast operation, large local storage space, need specific factors cantelecommunications, The argumentation General buoy the overall program is raised. Basedon it, OMAP dual-core processor as the core system hardware design is designed. It mainlyincludes analog-to-digital conversion, network transmission, data storage, and level shifting.And ADS1174is the circuit analog-to-digital conversion chip as four-channel16-bit parallelsampling chip. Complete hardware circuit drawing and making according to the design ideas.Through the research of shared memory, the Dual-core communication solution is used toimplement the replacement of the op program on chip. Complete the system of softwaredesign on the basis of the hardware design. Transplant Uboot to boot the system, andcomplete the network transport functions. By the CCS program the board programs,including analog-to-digital conversion, network transmission, data storage, and the dual-corecommunication.
