Elevator Control Chip Design

With the rapid development of urbanization, high-rise buildings and intelligent buildings will emerge in large numbers. At the same time, the conditions for the continuous improvement of elevator control systems are provided by the rapid development of integrated circuit and fieldbus technology. As the modern elevator control system is constantly improving in terms of safety, stability, and humanization, it is particularly necessary to upgrade the original system in terms of communication and motor control methods. At present, elevator control mainly includes several control methods such as relay control, single-chip control, PLC control and FPGA/CPLD control. This article uses FPGA as the control method, which is a high-density application specific integrated circuit that can be customized and configured by the user. The FPGA-based elevator control method has the advantages of high reliability, convenient maintenance, short development cycle, and strong flexibility. It can complete complex control tasks and has become the development direction of elevator control.This article takes the three-story elevator control system as an example, and uses Verilog to design a set of control chip design, including button request module, state control module, motor drive module, switch door control module, and frequency divider module. Finally, the FPGA development platform was used for implementation and verification.
