Electro Hydraulic Goods Elevator

Abstract: This paper present a microcontroller based elevator control system. An elevator is a type of vertical transport equipment that efficiently moves people or goods between floors of a building. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack. This paper mainly focuses on using microcontroller to control the circuit and building the elevator model. Limit switch is used for the elevator position. Hydraulic fluid cylinder is used to control the up and down movement of the elevator car. Push buttons are used to call the elevator car. The elevator position is described by using the display unit.
