Design of Auto Lifting Control System Based on PLC

Lifting system is widely applied to different range because it is quite convenient and intelligent, such as high-rise buildings. In order to improve the reliability and equipment working efficiency of the automatic control system, programmable controller (PLC) as the core controller is properly used during the control system design in the paper. Through the mechanical working method, the software control is used instead of more complex relay-contactor control which can greatly improve the mechanical failure inspection and maintenance convenience.
