Design and Implementation of a Novel Intelligent Curtain Module System

Intelligent curtain system can be time switch and achieve more advanced control functions as scene control. The paper introduced curtain applications, electric curtain classification as well as intelligent curtain with new functions. Based on requirements analysis on intelligent curtain of hotel room, functional division of intelligent curtain module was determined. MCU control circuit, data storage circuit and motor drive circuit were designed. The I/O interface of AT89C4051 was used to implement functions of key signal input, voice broadcast or timekeeping. CAN bus was used for communication to complete required curtain linkage function when guest plug card.
