Study Of Optimal Control Method Of Double-deck Elevators

With the rapid development of society,the rise of large and medium-sized cities makes the scarcity of land resources,driven by the rapid development of high-rise buildings,high-rise buildings,and then people on the elevator system requirements are increasingly high.Through a traditional elevator to increase the area of the elevator or increasing the number of the elevator hoistway to improve the elevator group control system service level,which means to sacrifice a portion of the available space.Double car elevator came into being,it has a different structure,can reduce the construction is repeated in the elevator shaft area,and can improve the elevator transportation performance,with higher economic value.Now,how to optimize the control of double car elevator group operation,realize in the discrete,real-time,nonlinear dynamic environment,do intelligent assignment elevator,reduce energy loss,improve the service quality of the elevator,is currently a hot research at home and abroad.The main contents of this paper are as follows:Firstly,this paper introduces the development of the elevator group control system and the status of elevator group control algorithm.Secondly construct reserved registration double-deck elevators control system based on the analysis of structure and operating characteristics of Double-deck elevators,and describes the working principle,the structure and operating rules of the system in detail,finally,look the objective layer consist with 3 hoist way 6 elevators as the research object,integrate the double-deck elevators operating rules(Waiting time,the incidence of long waiting ladder and energy loss)and multi-target control strategy,Construct objective function suitable for double-deck elevators group,propose optimized control method of double-deck elevators group based on adaptive guide to genetic algorithm,In the Matlab environment,we prepared a double car elevator group control system simulation program,and compare with the traditional elevator control system simulation.Simulation results show that the control method of text study design is better than conventional elevator control system in the average waiting time,long waiting times and parking ladder incidence aspect,achieved three transportation modes which are peak uplink,peak downlink and inter-layer traffic,when passengers arrive at the rate of different situations,efficient transport of Double-deck elevators group control system,improved the quality of elevator service,reduced the energy loss of the system.This control method has a strong ability to adapt,better robust,In line with requirements that people have on the elevator group control system of quality of service and the policy of our country on the energy conservation,provide technical support and theoretical basis for the project application.of Double-deck elevators Group Control System...
