晨昏控制器在实训应用中的研究

Research on the Dark and Dawn Controller in Practical Training

用分立元件和集成 5 5 5定时器分别实现的晨昏控制器 ,供学生实训选择 ,不仅能激发学生的兴趣 ,加深对模拟电子电路和数字电子电路的理解 ,而且能使学生在有限的实训期间认知更多的电子元件及其作用 ,从而收到事半功倍的效果 ,提高实训含金量。

Dark and dawn controller uses discrete component or 555 integration. The students can choose either of them during their practice training. This will not only stimulate the students' interests but also improve their understanding of the analogue circuit and the digital circuit. It also enables them to learn more about the electric component during the limited practical training time, so that the training becomes more efficient and the effect greater.
