【正文】 toried storehouse. Elevator is a mechanical and electrical equipment which principle is applied by electrical control technology, the microprocessor technology and system engineering. This paper is based on AT89S51 as the core control elements designing an seven elevator simulation system, which can carry passengers to any floors and through LCD1602 display elevator floors, date， the same time the circuit application drawn is done by PROTEL99, it is using its general edition to plete the welding and plete physical testing of material objects. Using singlechip microputer control elevator can achieve a low cost, strong monality, flexibility result and it is easy to realize the plicated control ,this design is of practical use and applied value.
