A Self-contained Data Storage And Processing Platform Based On TMS320C6000

As the government Attaches great importance to ocean development,the buoy has been widely applied.The buoy system plays an important role in the acquisition of Marine acoustic information.The self-capacitance data storage system developed in this paper is based on a VLF working platform with vector hydrophone,the system can store the signals collected by the vector hydrophone.The platform also has an electronic compass to correct the direction when processing the data in the post processing.The central processor of the self-capacitance storage system selects the TMS320C6416 chip produced by TI company.The digital circuit is centered on DSP,and the power supply circuit,data acquisition circuit,data transmission circuit,data storage circuit and synchronous circuit are designed.The analog circuit use the integrated transport chip to amplify and filter the analog signals collected by the vector hydrophone.In the third chapter of this article,the development process of the software part is given and the FAT32 file system is designed.The collected acoustic vector information,depth gauge information,compass information and GPS information will eventually be stored as dat file in CF card.After designing and fabricating the circuit board,begin to enter the laboratory debugging to make the electrical performance index reach the target system.Finally,it was verified by a marine experiment that the very low frequency subscript of this set of signals can correctly receive signals and that the depth gauge and compass information can be correctly collected.It is verified that the compass correction of vector acoustic signal will affect the direction finding performance of the submarine.The result of marine experiment also proves that this buoy system is stable and reliable,and can correctly pick up the marine environment noise in practical application.
