摘要
现实生活中很多场合,窗帘尺寸大且彼此之间间隔较远,这给窗帘的控制带来了很多不便。利用主从式多机通信协议,合理选择各器件的参数,实现了窗帘控制系统主控制器与从控制器的电路设计。串行通信过程中,将TTL电平转换为MAX232电平,可以实现控制信号的远距离传输,并且可以节省传送线。本设计已经做出实物并通过验证,可以远距离控制窗帘,真实可行。
In our daily life,Curtain's size is large and distance between each other is a bit far on many occasions,which brings a lot of inconvenience to the curtain control.By using master slave communication protocoland a reasonable choice of the parameters of the device,the curtain control system main controller and the slave controller circuit has been designed.By converting TTL level to MAX232 level,control signal can be transmitted far in the process of serial communication,and can save the transmission line.This design has been made and verified successfully,which can control curtain far away.
