Development of Elevator Intelligent Safety Control System Based on PLC

In order to ensure the elevator safety running, this paper discusses the tractive elevator safety control process. The flow chart of PLC of automatic control door is introduced. Work field section controls the elevator by using PLC. Configuration software is the technology platform in monitoring section, which completes the process of elevator monitoring. The elevator safety control system based on PLC is developed, and the system is in a stable and reliable state through the actual test.
