Elevator controller implemented on an electric train model

Abstract

Embedded system applications are ubiquitous; aircraft, passenger cars, domestic applications are all controlled and programmable using one or a set of synchronised micro-controller boards designed to control every external device attached. This thesis presents the design and implementation of an elevator control system (using an electric train to simulate the actual elevator system). The system is implemented using the C programming language and two Silicon Labs C8051F020 developing boards, connected together via a serial communication link. The elevator controller is designed for a four level system however it can be modified to cater for more floor levels. The Normal 'Up' and 'Down' arrows found outside the elevator hall are replaced by numeric destination buttons. The aim of the destination-approach buttons is to improve both the elevator user interface and to minimise the traffic system in an elevator. The design of this elevator controller is based on an effective logic function in the gist of reducing elevator's power consumption, the use of resources and preventing the system to operate in a first come first served procedure. Different testing procedures were performed to analyse the system performance and the results obtained were as expected.
