Sistema de sincronismo entre a colhedora de cana-de-açúcar e o transbordo.

Abstract

One of the problems found in the automated crop of the sugarcane is the lack of synchronism between the harvester and the infield wagon, causing product and time losses. The objective of the present research is to develop a system capable to synchronize the sugarcane harvester elevator with the infield wagon. The communication between the equipments is wireless. The developed system allows the harvester to identify the presence of the infield wagon and control the hydraulic motor of the elevator, turning it on/off. Data transfer informing the speed, beginning and end of harvesting is on radio frequency. Two ultrasound sensor, coupled on the elevator and a microprocessor, manage such information generating a correct synchronization among the implements. The system was tested at laboratory and in field, executing its function correctly, maintaining the two machines in synchronization, indicating and alerting to the operators their relative positions.
