Abstract
This thesis bases on the actual application requirements of lift, proposing a kind of hardware design of the control system, which defines the system's overall design, hardware structure and part of the corresponding program modules. The lift control is achieved with 89C51 as the master chip, optical encoder as the detection core of the location signal. The content is composed of five parts as flowing: the development background of the elevator control system, analysis of the composition module of the control system, control circuit schematic design, the PCB diagram of the control system, program design for part of the control process. The design process involves specific features of the electronic components, choosing the types and packages of the electronic component, application of Protel for designing circuit board.
