Protótipo de elevador didático utilizando controlador programável com PIC16F877A

Abstract

This work presents the retrofitting of a prototype teaching lift using a Programmable Logic Controller with PIC 16F877A as main logical drive and a frequency inverter CFW 09 to trigger and control the three phase induction motor. This prototype was mounted on a metal frame, courtesy of a company elevator installed in the city of Curitiba, which used obsolete technology with electromagnetic control the market. Thus, it is possible to present the academic environment and the principle of operation of an elevator control system as well as to use the prototype as an academic activity. Distributed into five chapters will be described since the submission of the project proposal, the methodological procedures described in Chapter 1, the literature review in Chapter 2 as well as a history of the lift, its operating principle, control logic and safety issue the elevator. The steps of assembling the prototype can be seen in Chapter 3. Chapter 4 describes the testing and validation of the project by the end of Chapter 5 describes the expectations reached at job completion.
