The quality of the lift performance of the impact on people39。s lives being more and more obvious, it must strive to improve the performance of elevator systems, and ensure the operation of the lift is safe, reliable and energy efficient. The traditional elevator control system uses logic of the relay to control circuit, this kind of controls easily to be crash, maintains inconveniently, the movement life is short, and that occupying a large area of space, it being eliminated gradually. Microcontroller that microputer (SingleChip Microputer) 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 me
