I. INTRODUCTION
The elevator is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel or other structures. 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. Elevators are prevalent throughout many multi-level structures. They control the flow of foot traffic between various floors of buildings, they allow disabled persons to access upper-level floors, and they facilitate the movement of large items (such as furniture and office equipment) between various levels of the building. The elevator system exists to help users get from one floor to another in the building. It is particularly useful for those with physical handicaps who may find it difficult or impossible to use the stairs. It is also quite useful for moving large or heavy objects between floors. The elevator control system is an integral part of the elevator system which, as its name suggests, controls the various components of the elevator system to ensure the system functions properly. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles/forks of hay elevators.
