Automated freight elevator prototype, driven by a frequency inverter, monitored by a supervisory and controlled by a microcontroller

Protótipo de elevador monta-carga, automatizado, acionado por inversor de frequência, monitorado por supervisório e controlado por microcontrolador

Resumo

In view of technological advances, automation has gained more and more space, and has become indispensable in the process of automating equipment. In this way, the objectives of this project are to develop an automatic drive system, using alternative technology, to replace an electromechanical drive system, of a freight elevator prototype. To achieve the desired type of drive, two types of circuits were designed, the power circuit, formed with a frequency inverter, geared motor, and protection devices. And the command circuit consisting of sensors, relay actuators and a microcontroller, both controlled and monitored by a developed synoptic screen. The project can be activated by a remote station or locally by pushbuttons, the data transmission will be through the Ethernet protocol and the data processed and stored on the behavior of the current electric and the alarms in a database. The results obtained were quite satisfactory, and with that allowed the design of an integrated system with several devices from different manufacturers, to automate a prototype of a freight elevator.
