"基于PLC的先进电梯控制系统设计与优化"

With the rapid development of modern cities, the number of high-rise buildings has been increasing, making elevators an essential mode of transportation for people in their daily lives. The performance of elevators has a significant impact on people's lives, and it is crucial to continuously improve the efficiency, energy-saving, and safety of elevator systems. By utilizing PLC technology to control elevator signal systems, a complete elevator control software has been developed to enhance the level of elevator control and improve the comfort of elevator operation, achieving an ideal control effect. This system features advanced, reliable, and cost-effective characteristics. The elevator control system has both manual and automatic functions, including floor selection, hall call, floor selection, direction selection, and other functions. It embodies the characteristics of collective selection control. Keywords: elevator, PLC, ladder diagram.
