电梯的出现无意改变了人类的生活,而与电梯有关的类似设计却在公元前256年的古希腊就已经出现了。1955年,世界上第一台计算机控制的电梯被发明,它采用的是真空管控制,七年之后,美国发明了速度能够达到8米/秒地超高速电梯。虽然目前电梯已经进入了控时代,但是基于PLC控制的电梯系统仍然有其可以运用的一面,所以本文在PLC程序的基础上,对电梯控制系统的设计和实现进行了分析。

The appearance of the elevator has no intention of changing human life, and similar designs related to elevators have emerged in ancient Greece in 256 BC. In 1955, the world’s first computer-controlled elevator was invented. It used vacuum tube control. Seven years later, the United States invented an ultra-high speed elevator capable of reaching a speed of 8 meters per second. Although the elevator has entered the era of control, but the elevator system based on PLC control still has its side that can be used, so this paper analyzes the design and implementation of elevator control system based on the PLC program.
