Hello Friends .
In high school I have done an elevator control circuit I want to share with you . I’ve designed a 4-story elevator . What floor is the elevator on each floor, a display showing that , Recall button , and the LED are busy . Likewise in the display in the cabin , which was on the floor , one for each floor indicating LEDs and buttons are available. There are olarakda PIC16F877 microcontroller .
All cards must be cascaded together . So each separate cable from the motherboard is not going to fold . Instead card cables from the motherboard 1st Floor , 1st Floor 2nd Floor card from a card I made to enter . The most recent 4th Floor card will be attached to the card in the cabinet .. Camping is moving cab card for the connection between the 4th Floor card I made with thin flat cable . Cable is flexible up and down the cabin is important for comfortable movement . Cables quite a few more . To get rid of cable clutter I would advise you to keep the cables as thin as possible . :)
Tickets must be inter- connections in the following order form .
Move up and down the lift motor may be any low-speed geared motor is. The main card is made with two pieces of relay direction control.
Before I forget, let me tell in the presentation. Each floor has one magnetic switch ( Reed Switch ) is necessary to add. This magnetic key card to the links located on each floor needs to be done. On the cabin to prevent the movement if you place a small magnet when faced with the cabin amnyetik switch circuit that we understand what floor.
Elevator is a model I’ve made with MDF.
All I have to say. Circuit is definitely working. Especially pay attention to the cable connection. You soldered a wire in the wrong place can cause grief for hours.
