Design of Intelligent Hanger Based on Single Chip and Pro-E

A new type of intelligent hanger was designed based on single chip and Pro-E software. 3D entity model of actuator and cover curtain mechanism are established by Pro-E. Wings structure of hanger mechanical part was adopted screw rod and motor combination of the lifting mechanism can make the wings outspread and fold, unique cover curtain structure was adopted. Cover curtain rolls up and down through the motor driving. The control system adopts AT89C52 single chip. According to the information that coming from the rain sensor and the temperature sensor, two stepper motor’s positive and negative rotational motion was controlled. So as to realize automatic adjustment when it rains. The hanger will be automatically closed when the temperature is higher than expected, and the hanger will be automatically opened when the temperature is less than expected. The hanger that has been produced has a good performance.
