FERNANDEZ-MORALES, Flavio Humberto  e  DUARTE, Julio Enrique. Automation for the monitoring and control of a generator with electric start. Entramado [online]. 2015, vol.11, n.2, pp.262-271. ISSN 1900-3803.  https://doi.org/10.18041/entramado.2015v11n2.22241.

This work deals with the development of an automatic system to monitoring variables and controlling the process related to a threephasic genset with electric ignition. The process to be controlled is: the genset powering on and off; the connection and disconnection of the genset and the grid to the load, also called electric transfer and the actuation of the preheating system. It was designed a distributed system, composed by five microcontrolled modules, which allows the capture and visualization of the most important variables related to a genset, together with a secure operation of the machine. An interesting point was the development of a communication bus that allows the exchange of information between the modules of the system, to a distance up to 20 m. To do this, it was adapted the 12C protocol, initially conceived to communicate integrated circuits located in the same board.
