Group control elevator dispatching system based on S7-1200 PLC

摘要

With the social progress and the acceleration of the pace of life, the traditional elevator has not been able to meet people’s needs. At present, most group control elevators simply distinguish the single or double layers, and their efficiency is slightly improved compared with the traditional elevators, but the problem has not been fundamentally solved. Based on Siemens S7-1200 PLC, TIA portal and WinCC, group control elevator dispatching system is designed, using six ten-floor group control elevators as model, to analyze the model of group control elevator, implementation method of the software system and the algorithm of group control elevator dispatching system. This system not only makes up for the large computation and difficulty of the dispatching system based on neural network design; Moreover, it avoids the difficulty of modifying the rule base of dispatching system based on fuzzy control design. Through the simulation test data, it is found that the system can improve the elevator riding time, waiting time, long waiting rate and other indicators. And the conclusion can be drawn that group control elevator can reduce the energy consumption and improve the efficiency of elevator operation.
