自动伸缩门原理——电路原理
Principle of automatic expansion door circuit principle
自动伸缩门的核心部分就是单片机了，它分别外接反相三态缓冲器与电极开路反向门以获取动态扫描短码来获取信号。由于单片机没有大量的运算数据及缓存的数据，所以能够一直保持快速的运转。经过高速的运算处理，大盘即将信号转化为模拟的信号并输出，电动机得到驱动信号后则开始运转，产生机械就能完成自动伸缩门的开关了。
The core part of the automatic expansion door is the single chip microcomputer, which is respectively connected with the reverse Three-State Buffer and the electrode open reverse door to obtain the dynamic scanning short code to obtain the signal. Because the single-chip microcomputer does not have a large number of calculation data and cached data, so it can keep fast operation all the time. After high-speed operation and processing, the large plate converts the signal into analog signal and outputs it. After the motor gets the driving signal, it starts to operate, and the generating machine can complete the opening and closing of the automatic expansion door.
