新型模块式可视化模拟电路实验箱的研制

Development of a New Modular Visual Analog Circuit Experiment Box

该文针对目前用于模拟电路课程实验、实践教学的实验箱存在可操作性不足、接线复杂、不易维护和综合性体现不足等问题,介绍了一款成本低、操作方便、易于维护并具备可扩展的模块式可视化模拟电路实验箱,以提升初学者的学习兴趣和学习质量。该实验箱能够完成《模拟电子技术基础》教材中的大部分模拟实验,并可通过子板设计进一步扩展。同时通过配置母板上的微处理器所具有的模数转换、数模转换和串口通信等数字功能结合PC机系统软件,进一步实现模拟电路实验的PC机端控制与显示,提升模拟电路实验的可视化功能。实验结果表明,该实验箱在可操作性、综合性和可视化方面优于市面上现有的模拟电路实验箱。

Aiming at the problems of the current experimental box used for analog circuit course experiments and practical teaching,such as insufficient operability,complicated wiring,difficult maintenance,and insufficient comprehensive manifestation,this article introduces a low cost,convenient operation,easy maintenance,and scalable modular visual analog circuit experiment box to improve the learning interest and learning quality of beginners.This experiment box can complete most of the simulation experiments in the"Basics of Analog Electronic Technology"textbook,and can be further expanded by the sub-board design.At the same time,by configuring digital functions such as analog-to-digital conversion,digital-to-analog conversion,and serial port communication with the microprocessor on the motherboard and combining the PC system software,the PC-side control and display of the analog circuit experiment is further realized,and the analog circuit experiment is improved.Visualization.Experimental results show that the experiment box is superior to the existing analog circuit experiment boxes in terms of operability,comprehensiveness and visualization.
