Automação em raspadora de pneus utilizando controle numérico computadorizado com controlador lógico programável integrado

This work studies and develops a machine automation for tyre truing. It is discussed industry development, industrial processes automation, tyre-recycling process, advantages of tyre reuse for preservation of the environment and probable gains from the automation of part of the tyre-recycling process. In this text, it is detailed the work done to configure, program and optimize the truing process through automation components as CNC, PLC and drives. Tests and simulations are performed to determine the payback necessary period in productivity and profit gains

Proposta de controlador de carga com MPPT utilizando LabVIEW

This paper presents one proposal of the energy management's model system using photovoltaic panels. The module proposed seeks to monitor photovoltaic panels, which have intermittency in power generation caused by environmental or load conditions, in order to control the coupling between the panel and the load - through the charge controller, of aiming that the panel's operation will be always on the maximum power transfer point as possible. For this, it used the maximum power point tracking technique - MPPT, implemented in LabVIEW software, also utilizing the data acquisition card NI myDAQ. In addition, it was implemented the controller access remote module, from the sharing of network data, so the panels performance can be through a tablet, monitored and controlled with no need for direct contact with the Supervisory server
