Abstract

The impact of elevator performance on people’s lives is becoming more and more significant. Therefore, efforts must be made to improve the performance of the elevator system to ensure that the elevator operation is efficient, energy-saving, safe and reliable. The traditional elevator control system uses a relay logic control circuit. This control is easy to malfunction, inconvenient to maintain, and it is short in operation life, but large in space, and is gradually being eliminated. The PLC control system has become the most widely used control method in the elevator control system due to its high operational reliability, and is convenient to use and maintenance. And it has strong anti-interference, short design and debugging cycle, etc. It is also widely used in the technical transformation of traditional relay control systems.
