The elevator has become an important tool for high-rise buildings. It is safe, reliable and vertical fluctuation in high buildings, which works both in improving working conditions and reduces labor intensity. At the same time, the elevator makes our life much easier and provides a powerful guarantee for the modernization in our country. Applications of elevators are wide. We can see them in hotels, restaurants, office buildings, shopping, entertainment, warehouses and residential buildings. Therefore, elevators have become an indispensable facility to us, Using single-chip microcomputer control of elevator has a low cost, versatility, flexibility and easy to realize complex control, EST. Based on SCM elevator control system of intelligent design separately form the system requirements and hardware design, software design and so on several parts design, introducing the AT89C51 series microcontroller as the core, and combined with 74LS245 and LED etc chip and with matching assembler language software on concrete realization method of the elevator simulation, this method can not only realize the basic function of the elevator, and can set the elevator nonstop, abrupt stop, blackouts, thus, can repair function such as the realization of elevator intelligent control and the corresponding optimal route choice, improve elevator utilization.
