摘要
设计了基于NI ELVIS的心电信号测量实验系统。该实验系统包括一整套电路设计开发流程,首先由学生在Multisim上进行电路设计与仿真,然后利用NI ELVIS原型开发板完成心电采集电路的搭建,最后通过LabVIEW图形化开发软件实现心电信号的实时动态显示,从而完成整个心电测量实验。实践表明,该实验系统能很好地完成心电信号测量的实验,并具有可操作性,能够灵活、方便地为学生提供一个亲手实践的实验环境,激发了学生学习兴趣,结果清晰明确,可以更好地帮助学生理解相关概念和理论知识。
In order to innovate the traditional experimental teaching mode,an experimental system of ECG measurement based on NI ELVIS II is designed.A set of circuit design and development process is included in this system.Starting by students to design and simulate a circuit with Multisim,the ECG data acquisition circuit is built on NI ELVIS II.Finally,ECG signal is displayed in virtue of LabVIEW.Practical experiments show that with the aid of NI ELVIS,Multisim and LabVIEW,the system can successfully perform ECG signal measurement work.It has a great maneuverability and flexibility which can provide students a hands-on laboratory environment,and arouse students＇ learning interest.The clear result also can help student deepen the understanding of the theoretical knowledge and enhance the ability to practice.
