Abstract：Abstract: High-rise building has become a major symbol of urban construction. In order to facilitate people’s travel and work, high-rise building design introduced building automation and intelligent technology, elevator has become a necessary operation tool of high-rise road building. Therefore, strengthening and improving the design of elevator appearance and automatic control system has become an important task in high-rise building planning. The elevator design a three layer, through software and hardware to cooperate, make its have tests the elevator in the elevator in heavy weight, when the elevator overweight with sound and light alarm to remind, prevent damage of excessive weight makes the elevator, using digital tube display the current floor, reach the corresponding floor lamp light, and real-time display of elevator running up and down. In order to prevent the elevator from sandwicking users when closing, infrared tube detection is used to detect whether there is someone. When someone is detected, the elevator door can not be closed to prevent users from being added to the elevator door.
