Abstract


An escalator is a moving flight of steps—a conveyor transportation device to haul public between floors of a building consisting of a motor-driven chain of steps to haul up and down on tracks. It allows the step treads to remain flat to earth surface. The establishment and operation of escalators requires large space and consumes substantial amount of power. The escalator used in public spaces runs idle wasting power, a precious resource. Safety of motion on escalators is also a concern. This paper addresses these issues with design of control system using PIC16F76 microcontroller. The escalator is made to operate in dual mode with the help of Laser–LDR sensor only in the presence of humans, thus reducing the need of separate escalators for upward and downward motions. Safety feature is added to stop the escalator in emergency. The detailed design procedure and algorithm is presented in this paper.

Keywords: Escalator, dual mode, microcontroller, sensor, power, signal conditioning.
