Design and Practice of an Elevator Control System Based on PLC
Abstract
This paper describes the development of 2 nine-storeyelevators control system for a residential building.Thecontrol system adopts PLC as controller,and uses aparallel connection dispatching rule based on"minimumwaiting time"to run 2 elevators in parallel mode.Thepaper gives the basic structure,control principle andrealization method of the PLC control system in detail.It also presents the ladder diagram of the key aspects ofthe system.The system has simple peripheral circuit andthe operation result showed that it enhanced thereliability and performance of the elevators.
