In this modern era, elevators have become an integral part of any commercial or public complex. It facilitates faster movement of people and luggage between floors. The elevator control system is one of the most important aspects in the electronics control module that are used in the automotive application. Usually elevators are designed for a specific building taking into account the main factors like the height of the building, the number of people traveling to each floor and the expected periods of high usage. The elevator system is designed with different control strategies. This implementation is based on FPGA, which can be used for a building with any number of floors, with the inputs and outputs specified. This controller can be implemented for an elevator with the required number of floors simply by changing a control variable in the HDL code. This approach is based on an algorithm that reduces the amount of computation required, focusing only on the relevant rules that improve the performance of the elevator system group. The elevator controller was developed using Verilog HDL and was successfully implemented in a Xilinx Artix7 FPGA.
An elevator is the vertical transport equipment used to carry luggage or passengers between the floors of a building. Elevators plays a vital role in both commercial and residential areas. Traditional elevator control systems rely mainly on relay logic, PLC and microcontroller, but the main disadvantage of these systems is that they have a reduced number of inputs and outputs. An elevator can be considered as a complex reactive system that requires parallel event processing with a number of inputs and outputs. Therefore, FPGAs make a better solution for the implementation of an elevator controller with added advantages of reconfigurability, lower power consumption, lower response times and flexibility in design expansion. The elevator control system is basically a finite state machine.
