Along with society's development, the high-rise construction becomes the urban landscape at the same time, also has brought a series of security problem, How and most main is the high-rise construction to deal with the fire and so on emergency case the threat. Once the high-rise construction has the fire, the personnel dispersal is a thorny question. Therefore the high-rise construction elevator's emergency dispersal function will also will certainly to integrate in the elevator group control system.The fuzzy control technique was applied to elevator group control, and the research was made on these key problems includeing, elevators normal working and emergency evacuation working ,identifying the passenger's transportation pattern and the algorithm of elevator group controls, The paper introduced the development of fuzzy elevator group -control system and the domestic and overseas study actuality briefly. The paper also analyzes the research and development of high-rise construction emergency evacuation system. The paper analysises the traffic ariableness described traffic characters, and then the traffic componemt and the traffic intensity are regarded as the input variableness of fuzzy reasoning. The fuzzy reasoning rules identifying traffic patterns was summaried. Analysises the two state of Elevator working and two working model of the whole structure; The paper analyzes detailedly traditional attempering algorithm that is short of the veracity and the maturity etc, then a more reasonable new evaluation function is built up. The weight average of the most important four evaluation targets, including the low average waiting time, the low long-time waiting percent, the low riding-power consume, the low average riding time act as the evaluation function. The paper makes a detailed study on realizing the fuzzy reasing of these four control targets, including the choice of input variety, the input variety calculation, the choice of member function, and the fuzzy rule table etc. Emergency evacuation , A dispatching method combining static division and multi-objective optimization algorithm based on fuzzy control is proposed.And the high-rise construction emergency evacuation characteristics as well as the algorithm design are presend.MATLAB using the object-oriented programming technology, designed by Fuzzy Elevator Group Control System group control algorithm for the simulation, The simulation result of the fuzzy elevator group control syetem shows evident decrease on the average waiting time, the long-time waiting percent, the riding-power consume, the average riding time compared to traditional centralizing-select control system.It show great superior and feasibility for fuzzy elevator group control system.
