基于NI ELVIS Ⅱ+的信号处理技术虚拟仿真开放式实验教学探析

近几年,国家重点研发科技方向之一为海洋领域,目前水声工程领域的各科研单位亟须从事水声信号处理技术的研究型人才。针对这一需求,水声工程专业研究生课程教学改革必须体现"基础理论、分析方法和工程实践技术并重"的理念。在研究生一年级的课堂教学环节中,研究生可以灵活进入国家级开放式水声教学实验中心,通过调试NI ELVIS Ⅱ +信号处理实验箱,完成水声信号处理基础案例设计。这不仅可以开阔研究生的工程实践能力视野,也为研究生的毕业设计和未来从事科研工作建立一定的水声信号处理技术储备。

Research of Virtual Emulation Open Experiment Teaching Based on NI ELVIS Ⅱ + Signal Processing Technology

In recent years, one of the key development directions of the state is the ocean field. At present, the research institutes in the field of underwater acoustic engineering urgently need talents engaged in the research of underwater acoustic signal processing technology. In order to meet this demand, the teaching reform of undergraduate course of underwater acoustic engineering specialty embodies the idea of "laying equal stress on basic theory, analysis method and engineering practical technology". During the first year of postgraduate students and theoretical teaching, postgraduates can flexibly enter the national open underwater acoustic teaching experimental center and complete the basic case design of the underwater acoustic signal office independently by debugging the NI ELVIS Ⅱ+ signal processing experimental box. This can not only broaden the engineering practice ability of graduate students, but also establish a certain reserve of underwater acoustic signal processing engineering technology for graduate students to participate in scientific research projects during graduation design work and after employment.
