Desenvolvimento de sistema de controle automático de um termonebulizador agrícola para controle de geadas em plantações

Abstract

The climatic phenomenon known as frost causes losses in many plantations in Brazil’s south and southern regions. As it is a climatic condition it cannot be avoided, but there are many ways to minimize the effects that it causes in plantations. The current project is about the thermal fogger control, an automation method to avoid the effects caused by frost. At first, the motivation for this automation system was studied. This study has been proven as a good project because all the process is done by the operator who has to do the weather analyses and activate the thermal fogger equipment at winter nights when generally the frosts happen. After that, a system was developed to monitor the weather conditions that cause frost and trigger the machine. Also a supervisor system was developed to monitor the entire process. The study results could help to familiarize people with this equipment and this technique to avoid frost in the winter. Also it could improve the way that the machine is used, so the losses in plantations caused by frost can be minimized by this process.
