摘要
数字调光系统结合了单片机、模拟电子技术和数字电子技术知识。将其引入电子技术实验教学有助于培养学生的学习兴趣和提高电子技术知识的综合应用能力。在叙述数字调光系统和可控硅基本原理的基础上,介绍了一种数字调光系统的设计方案。该系统由单片机产生触发信号,控制可控硅的触发角以实现调光,通过键盘输入确定调光亮度,并由LED数码管显示。利用Proteus对系统进行构建,并作了仿真和测试。结果证明了该设计方案在实验教学中的可行性,为高校电子技术课程实施创新型实验教学拓展了教学内容。
The digital light-adjusted system involves the methods about MCU, analog and digital electronics. If the digital light-adjusted system is introduced into the electronic experimental teaching, it can improve the learning interest and the comprehensive ability of the designing-circuits for the students. It is convenient to perform the experiment for the students by Proteus. Based on the principle of digital light-adjusted and the thyristor, the design of a digital light adjusted system is introduced. The trigger signal is given and the conduction angle of thyristor is adjusted to control the light by the MCU. The light level is determined by the keyboards and is displayed on the LED displayer. This system is built and simulated by Proteus. The results show that it is feasible to use Proteus during the electronics experimental teaching. And the teaching content and strategy will be grown in the innovative experimental course of Electronics for the university.
