Abstract
Microcontroller that microcomputer (Single-Chip Microcomputer) gathering CPU, RAM,
ROM, the timing, number and variety of interface integrated microcontrollers. 51 various SCM
SCM is the most typical and most representative of a widely used in various fields. Elevator is
the application of the principle set machinery, electrical control technology, microprocessor
technology, systems engineering and other technical disciplines and branches of the integration
of mechanical and electrical equipment, which is building a permanent vertical transport. This
paper choice AT89S51 control of the core components, designed a new 8 storey lift systems,
using single-chip assembly language programming, transporting passengers arrived a floor, it
also shows the elevator floor and downlink. SCM control elevators low cost, versatility,
flexibility and ease of large complex control advantages.
Key words: Single-Chip;Microcomputer Elevator;control
