"基于PLC和变频器的电梯控制系统设计研究"
ontrol technology, and power electronics technology have developed rapidly, and elevators have become a symbol of urban material civilization. Especially in high-rise buildings, elevators are indispensable vertical transportation equipment. The traditional relay elevator control system, due to the large mechanical and electromagnetic inertia of the relay itself, greatly reduces the reliability and safety of the elevator system. In order to ensure the efficient, energy-saving, safe and reliable operation of elevators, it is necessary to improve the elevator control method. Programmable Logic Controller (PLC) developed for sequential logic control needs, is a digital computing operation electronic device designed specifically for industrial environment applications. PLC has fast processing speed, high reliability, and can ensure the elevator operates normally, safely, and reliably. At the same time, with the development of AC motor frequency conversion speed regulation technology, the elevator's traction method has gradually transitioned from the original DC speed regulation to variable frequency speed regulation. This not only can meet passengers' comfort and ensure smooth accuracy, but also can reduce energy consumption, save energy, and reduce operating costs. This paper will apply the variable frequency speed control method based on PLC to the elevator system and conduct research on this method. Keywords: elevator; programmable logic controller; variable frequency drive.
