基于TMS320C6748的自容式水听器
Self-Contained Hydrophone Based on TMS320C6748
摘要
Abstract
To further improve the data acquisition and processing capabilities of hydrophones,the researchers developed a self-contained hydrophone system based on using TMS320C6748 DSP chip.By taking advantage of strong floating-point data computing power of DSP,the system can achieve the collection,storage and processing of underwater environmental information.To meet the needs mentioned above,the researchers devised modules of power,ADC data collection,data storage and start-stop in the aspect of hardware circuits.The researchers also designed related software programs,including FFT calculation,PSD algorithm,data collection driven by ADC and definite-time start-stop.In the end,the researchers made a prototype to verify whether the requirements can be fully fulfilled.For instance,the researchers conduct tests of signal amplification effect,system power consumption and PSD algorithm correction to the prototype.The experimental results show that the test effect is good,and the system has high reliability and meets the preset functional requirements.关键词
