摘要：With the rapid development of modern society, large buildings are springing up like mushrooms in every city. The huge passenger flow demands more and more intelligent buildings. The carrying capacity of cluster elevators is one of the important factors. The carrying efficiency of elevators directly determines whether the vertical traffic is crowded, whether the building is energy-saving and whether the building is intelligent. Therefore, the group control strategy of cluster elevator is very important. Firstly, the paper expounds the characteristics of elevator, introduces the configuration of software and hardware of Programmable Logic Controller (PLC) and the production and use of WinCC, in order to realize the program design of elevator control. Then, relying on the elevator simulation training system EET-2017035, three elevator group control algorithms are designed for the ten-story integrated office building equipped with six elevators, and five most common passenger flow modes are equipped according to the functions of the building. Three kinds of group control strategies are tested. Several cumulative indicators measured by simulation platform are used as evaluation indicators. After dealing with each indicator, evaluation functions are constructed. The evaluation values of three kinds of group control strategies in five-passenger flow modes are calculated, and the comparison of group control strategy algorithms is completed.
