Title The control system of elevator based on single chip computer

Abstract Along with the continuously population growth and society development, the elevator can be seen in every aspect of our lives。 In this paper, the design of control system of four-story-elevator is explained in detail。 The paper also introduces the background and related principle of the control system of elevator。 The main circuit is composed by MCU control module, display module, keys module, alarm module and position indication light module ,and the design uses AT89C51 chip as the core。 Appropriate device models is chosen in this paper to comprise the modules of the single chip computer and complete the hardware circuit of the control system of elevator。 Then the construction of the circuit is completed with Proteus。 In addition,the plan and process of the elevator control is expounded in this paper , and the C language is chosen to compile Keil software。 In the end, Proteus 7。8 software and Keil software is applied to complete the simulation and debugging of the hardware circuit and the software design, to finally give the simulation results。
