A Study on Integrated Group Control System for the Disabled Elevators

When multiple elevators are installed in the building, control systems for each of the elevators, reducing energy loss by elimination of unnecessary movements and assigning appropriate elevators to passengers upon request are called the elevator group control system. However, the group control system of three or more elevators for the Disabled is being limited by the domestic laws and standards because it can not predict which unit will be called. In this paper, as an improvement plan, an integrated group control system of elevators for the general passengers and the disabled is proposed; its efficiency that decreases 16.9 % of waiting time is verified with comparison of the traditional separate group control systems. The proposed Integrated Group Control System does not violate the domestic laws and standards. Also its good performance is shown through computer simulations.
