Automatic Elevator Controller

Abstract

The elevators have embellish as an important part of any commercial or public complex in this new era. because, of these elevators it becomes very easy and quick for people and luggage to move from one place to another place. Most of the control and industrial applications are running on the traditional PLC technology abundantly as PLC has flexibility, lower cost and security compared to other techniques, but still a powerful alternative for PLC is needed. In recent years, FPGA has been the best replacement of PLC to implement control algorithms in industrial, digital signal processing, video and audio applications as well to perform control tasks.The entire world is facing the pandemic situation and in this period there is a need of Automatic Elevators. Automatic elevators runs without having floor buttons pressed. When passenger enters and/or leaves the elevator cab, door sensors detects passengers as they enters and/or leaves. After the doors closed, the elevator will starts to run by it’s own. Three level efficient elevator control system is designed by simply changing the state diagram, VHDL code is generated and used in Quartus to implement control system on FPGA Altera DE2-115. MODELSIM simulation software is used to simulate VHDL implementation of our proposed Automatic Elevator
