In this project we show that how we use the lift for multi level parking system.
In this project we use ic 89c2051 micro controller to run the lift. 89c2051 is a 20 pin controller from the 8051 family. 8051 family is a 40 pin ic. In this project we use one dc motor for the lift. Few reed sensor to monitor the lift and few sensor to check the availability of the space.
In this lift when we start the lift then we use start switch. After pressing a start switch dc motor start and when it reaches to the first floor then firstly we sense the floor by reed sensor. Reed sensor is magnetic sensor, when magnet connected to the lift is near by the reed sensor then reed sensor is activate and provide a signal to the controller. Controller sense the floor position and at the same time it checks the space position, if the space is there then lift stop automatically otherwise lift go forward to the next floor. In this project we use two floor and only two space for the parking. We design the lift for only two floor and two sensor, but it is possible to use this system for multi- floor and multi space option.
Here in this project we monitor the floor and space every thing by the reed sensor. So we use magnetic proximity switches to monitor the space and position of the lift.
We use Dc motor to lift the base platform of the lift
