CONTROL SYSTEM FOR ESCALATOR

Abstract

Many business stablisment utilize escalator that performs it’s function in a regular way of work. There is a big waste of eletric power, as in a good part of it there isn’t a transportation of user. The search for new sources shouldnt’t is the only worry in the context of energetic resource, but also the development of new technologies aimed an optimal use of this recourse. In the conjuncture, this project aims to establish a escalators’ control system, to optimize their use and reduce energy consumption of equipment. The system’s operation is based on the principle that, after a time ta,, a free flow of user, which this time is previously define by a statistician study the escalator reduce its speed, if it has passed a time tb, being tb>ta, the escalator is stopped. If we have the presence of the user, the escalator presents low acceleration, establishing the regular way of work without risks of utilization. The energetic economy happens when the escalator is stopped, or working with reduced speed. The project consists in replace the eletric command of the reversor and with the direct start, by a system’s control proposed. The reduction of the energy comsumption was valued by a statistician study, so trough it we can increase the use of the system and stipulate of the economy zone for the escalators with high and low user’s flow. This system is ecologically correct and contribute for the consumption optimized of electric power.
