What You Need to Know Before Design

Diagram Algorithm

  • The system will have two start and one stop button.
  • The door will open when the first start button (open button) is pressed.
  • When the second start button is pressed (close button) the door will close.
  • The door will continue to open if the close button is pressed while the door is opened.
  • If the open button is pressed while the door is closed, the door will continue to close.
  • If the stop button is pressed at any time when the door is open or closed, the door will stop and then whichever button is pressed will move in that direction.
  • When the door is closed, the door will be opened if you enter the vehicle. The door will close again after the vehicle has passed.

Diagram Solution

  • There are two start buttons that open and close the door.
  • The door can not be opened while the door is closed, it can not be closed while the door is opened.
  • If the stop button is pressed at any time when the door is open or closed, the door will stop and then whichever button is pressed will move in that direction.
  • There are one photocell at the entrance and exit of the door.
  • Photocells consists of transmitter and receiver.
  • Infrared light communicates between the receiver and the transmitter.
  • The receiver and transmitter are mounted mutually.
  • The photocell generates an output signal when an object enters between the receiver and the transmitter.
  • In this system, when the door closes and the first photocell detects the object, the door stops and starts to open again.
  • When the object exits, the second photocell becomes active and the door closes.
  • The stop button stops the entire system.
