Study on the Elevators＇ Planning ＆ Selection and Its Optimization Design

For the vertical transportation characteristic of high-rise buildings, this paper applies the expert system to establish the prediction model of elevators＇ traffic flow, and also studies elevators＇ intelligent transportation theory and traffic forecasting methods. Then the work mentioned before can provide a theoretical basis for the selection of the best lift configuration. By setting mapping variables in the prediction model, the model can be extended to the elevator traffic flow prediction of other high-rise buildings of different uses. This article proposes a elevator group control strategy, intelligent selection floor using external calling signal; Combining forecasting static partition and intelligent dynamic partition, applying feed-forward neural network technology, and setting the average waiting time, average riding time and the repeat degree of the destination floors as control objectives, we can fiind the best dynamic scheduling method of different transport modes. Five models, Up- peak traffic, down-peak traffic, lunchtime traffic, random interfloor traffic and idle traffic, are presented respectively. Model nesting are also realizes between the forecast model and the five transport modes. This paper adopts data mining and wavelet analysis technique, via the real-time simulation, to deal with the elevator operation data and to amend automatically the system parameters from time to time. Those measures can improves the operating efficiency and service quality of lift. This paper also studies the lift＇s operation modes under the circumstances of swing pendulum, fires, earthquakes and other special situations, and corresponding control and mitigation measures are also proposed to enhance the safeness and comfortableness of lift operation.
