Key Techniques Of Comprehensive Configuring Of Lift Traffic System In High-rise Buildings

The function realization of the modern high-rise buildings depends on both the efficient lift traffic systems and the related safe and reliable vertical traffic evacuation system.Therefore,the research of comprehensive configuring of lift traffic is of great significance.Considering the features of the modern high-rise buildings,on account of the deficiencies of the traditional analytical and map-table methods,etc.,by which it is hard to deal with the complicated traffic conditions.Firstly,A Markov Chain Monte Carlo(MCMC)based method is proposed to calculate the lift Round Trip Time(RTT)by the Matlab/GUI based software platform to conduct the optimal configuring under complicated traffic condictions.Secondly,the adaptive genetic algorithm is employed to conduct the dynamic zoning of Lift traffic to find the optimal zoning of lift running to improve the lift passenger handling capacity.Finally,in view of the characteristics of building emergency state(such as fire),the Cellular Automata,CA)and Pathfinder softw based simulation are conducted to verify,on one hand,the emergency evacuation safety and strategies on the other hand.The main work of the dissertation is as follows:(1)Based on the related literatures,the traditional lift traffic configuring method and the existing problems are analysed,and the traditional formulas under complicated traffic conditions are summarized.(2)Considering the deficiencies of the traditional methods,a MCMC based method is presented by the Matlab/GUI based software platform combined with the automatic configurring methods to conduct the optimal lift traffic configuring under complicated traffic condictions.(3)In view of the lift zoning operation problem,the self-adaptive genetic algorithm is employed to conducte the dynamic zoning of lift traffic,the optimal zoning is obtained based on the equilibrium principle of up peak traffic.So that the lift traffic handling capacity of high-rise buildings could be improved.(4)Finally,in consideration of the characteristics of high-rise building emergency state,in order to verify the emergency evacuation safety and to obtain the occupants evacuation strategies,the occupants evacuation models are constructed by employ CA and Pathfinder software to simulate the evacuation process respectively by lifts and stairs,and the optimal evacuation strategies which combine both lifts and stairs are obtained at last.
