Modernização de controle e funcionamento intermitente para escadas rolantes

Abstract

In many situations there is the need for moving people between floors, so that together with the idealization of work done by construction to reach the full functionality of the work. Analyzing aspects such as flow of users and robustness of designs are commonly used tools called "escalator" to achieve this goal. There is a large national park already using this technology, brought to Brazil in 40 years. As this tool is used primarily electricity to function, correlating global issues currently discussed under "sustainable" consumption of energy resources in all areas, this project aims to implement intelligent control for the activation and operation of this tool, aiming the economy and practicality in various aspects of using this means of locomotion of the day to day. The developed system acts directly on the escalator drive, controlling the operating speed of the engine based on user idle, causing the engines to be operated in accordance with the need to use, or even the state of "rest" interrupting the operation, situations that result directly in energy expenditure of the system. Such actions are performed using control microcontroller, which performs system diagnostics via physical sensors installed at strategic locations in the system and acts directly on the engine via a frequency inverter for speed control.
