Abstract


Currently, the main means of marine scientific research is the sound of water technology , all kinds of underwater acoustic equipment is constantly updated with the development of underwater acoustic technology . Acoustic release as a the essential acoustic equipment , many foreign companies have been series of products in the marine monitoring and ocean engineering , and domestic research in this area is very limited . In this context , the paper presents a set of acoustic release system design of the digital platform release function and response targeting capabilities . The paper designed aloud learning release system of digital hardware platform , software implementations are given . Based on the digital platform has RS232 the DSP6416 and FPGA deck unit , USB and Ethernet interface, has a strong digital processing capabilities and easy system expansion . Based on the the DSP5509 's the acoustic release digital platform with low power consumption . The paper discusses signal integrity , PCB design flow based on the signal integrity . The root dig the requirements of the system functions , system signal waveform design and testing programs , as well as the release function and answering positioning function software design . As the needs of a synchronous positioning system , digital platform used in the system , deck unit as part of the data acquisition , acoustic release as part of the synchronization beacon . The paper system synchronization crystal experimental screening design system application software , by experimental validation system performance .
