心率检测综合实验设计与实践

Design and practice of comprehensive experiment of heart rate detection

针对"电气技术实践基础"课程周期长、学生对所学知识掌握不牢的问题,设计了心率检测综合实验。该实验包括直流稳压电源、信号产生、数据预处理、心率计算、显示与报警等模块,涉及课上所学的多次实验内容,具有很强的综合性。教学实践表明,该实验可以提高学生的学习兴趣,培养学生分析与解决实际工程问题的能力,尤其是在条件受限的情况下灵活变通、大胆创新的工程素养。

A comprehensive experiment of heart rate detection is designed to solve the problem that students could not master the learnt knowledge well caused by the long course period of "Basic practice on electrical technology". The experiment includes DC regulated power supply, signal generation, data preprocessing, heart rate calculation, display and alarm modules. It involves many experiments in class and has strong synthesis. Teaching practice shows that the experiment can improve students’ interest in learning, train their ability to analyze and solve practical engineering problems, especially cultivate the flexible and innovative engineering literacy in the case of limited conditions.
