Abstract: With S7--1200 PLC, PLCSIM, TIA Portal and other software and hardware platforms, a newset of six 10-floor elevator group control system is built based on the characteristics of elevator group con-trol system. The system is easy to achieve centralized operation and maintenance with the cluster controlalgorithm realized by different destination operational sectors , priority dispatching capability , backup fol-low-up and multi-objective scheduling. An elevator simulation platform is used for the system simulationexperiment. The results show that the remote monitoring system under the group control system is stablereliable and simple to operate, and can realize efficient elevator scheduling.

Key words: group control strategy , elevator with priority dispatching capability, backup follow-up
