Group Elevator Design for Efficiency Aspects

Abstract

Designing a group of elevators in a building has long been recognized as an important issue to improve transportation efficiency, since elevator service ranks second after heating, ventilation and air conditioning as the main complaints of building tenants. This project implements the scheduling of a group of elevators with destination entry and future traffic information for normal operations and coordinated emergency evacuation to improve transportation efficiency. The operation of the lifts will vary for different modes like normal, emergency and priority modes. In the normal mode the lift in the nearest floor should move to the destination. The floors are identified through IR sensing. In the emergency mode when smoke is sensed in any of the floor all the lifts should move to that particular floor. Movement of the lift should be faster compared to the normal mode. In the Priority mode, whenever more than one passenger has requested for the lift, the lift should be allotted to the highest priority person, here the priority of the person is identified by the RFID tags.
