电气专业DSP实验教学模式改革探讨

Discussion on the Reform of DSP Experimental Teaching Mode for Electrical Major

针对传统DSP实验教学模式单一、以验证性实验为主的缺点,提出了验证性和设计性实验相结合的电气专业DSP实验教学模式改革。为了满足改革后的实验要求,研制出基于模块化思想的DSP实验平台,分别设计了DSP核心板、DC/DC直流斩波板和DC/AC变流板三种实验模块。改革后的教学模式根据实验内容选择相应的模块进行组合,可以给学生直观的认识,也可以为课外创新实践、电子设计大赛等提供硬件平台。通过教学模式和教学内容的改革,提高了DSP实验教学效果。

Aiming at the shortcomings of the single traditional DSP experimental teaching mode and the mainly confirmatory experiments,this paper puts forward the reform of DSP experimental teaching mode of electrical major combining confirmatory experiments and design experiments.In order to meet the experimental requirements of the reform,the DSP experimental platform based on modular idea is developed,and three experimental modules are designed:DSP core board,DC/DC DC chopper board,and DC/AC converter board.With the reformed teaching mode,we can choose the corresponding modules for combination according to the experimental content,which can not only give students an intuitive understanding,but can also provide a hardware platform for extracurricular innovation practice and electronic design competitions.Through the reform of teaching mode and teaching content,the teaching effect of DSP experiments is improved.
