Microcontrollers Based Intelligent Elevator in High-rise Residential Building

Abstract Since the reform and opening up, China's economy has been developing rapidly。Today, with the further development of China's urbanization, high-rise buildings are appeared in the cities。 Elevator to its fast, efficient, convenient and other advantages of the formal entry into the people's line of sight, is widely used in hotels, office buildings, residential buildings and other places, and as an indispensable means of transport tools, by the public praise。

In this paper, based on the MCU AT89C51 as the core control element, the assembly language is the basic programming language, and a four layer elevator control system is designed。Among them,the hardware part mainly by the microcontroller minimum system module, elevator internal and external key control module, digital tube display the current floor module, a light emitting diode display the destination floor module, elevator door opening and closing and uplink and downlink simulation display module and alarm display module and so on several aspects。Software part is written by assembly language program in keil software , and through the Proteus Software to carry out simulation and debugging。This design has realized the basic function of the elevator in daily life。

This paper has 18 pictures and a TABLE, with 26 references。
