有1-9章的课件，有相量变换，有传输线分析软件，很有用，非常好。

高楼电梯自动控制系统设计任务和基本要求：(1)系统控制的电梯往返于1-9层楼。
(2)乘客要去的楼层数可手动输入并显示（设为A数）。
(3)电梯运行的楼层数可自动显示（设为B数）。
(4)当A＞B时，系统能输出使三相电机正转的时序信号，使电梯上升；
当A＜B时，系统能输出使三相电机反转的时序信号，使电梯下降；
当A=B时，系统能输出使三相电机停机的信号，使电梯停止运行并开门；
(5)梯是上升还是下降各层电梯门外应有指示，各层电梯门外应有使电梯上升或下降到乘客所在楼层的控制开关。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
