摘要
针对电磁理论课程内容抽象,不易理解的问题,开发一种采用单片机作为控制核心的3D光立方显示装置来辅助电磁理论课程教学。系统采用STC12C5A60S2作为主控芯片,用16层16×16的灯层焊接形成LED灯箱,8个74HC573锁存器和一个ULN2803芯片作为外围控制,实现3维LED点阵动态图案显示电磁理论课程中核心理论知识。系统通过I/O口控制不同位置、不同时间的LED小灯的点亮状态模拟对应的电磁现象动画效果,让抽象的教学内容更为直观,学生可通过视觉感官来认知和学习,为电磁场与电磁波课程教学手段和方法的改革提供了新的思路。
In view of the abstract and unclear content of the electromagnetic theory course, a 3 D light cube display system is designed using single-chip microcomputer as the control core to assist the electromagnetic theory course teaching. STC12 C5 A60 S2 is used in the system as the main control chip,and eight 74 HC573 latches and a ULN2803 chip is used as the peripheral control. 16 layers of 16 ×16 light layers are welded to form the LED light box. Therefore, the display of the core theoretical knowledge in the electromagnetic theory course is realized, accompanied by the 3 D LED dot matrix dynamic pattern.The system controls the lighting state of the LED at different positions and different times through the I/O port, to simulate the animation effect of the corresponding electromagnetic phenomenon. The abstract content can be recognized and learned through visual sense, which explores a new idea for the reform of the teaching means and methods of the course Electromagnetic Field and Electromagnetic Wave.
