Sistema de advertência na operação de tratores

Abstract

Agricultural tractors make work easier and increase productivity in agriculture. Due to the increase in mechanization, the number of accidents involving tractors has increased significantly. Justified by this growing number of accidents, an electronic device that detects possible safety risks during the operation of small tractors was presented and developed in this work, with the objective of alerting the operator about safety during the different ways of using the tractor. To carry out the work, the safety devices already existing in tractors were presented, as well as a survey of electronic devices that make up the auxiliary safety system, such as controllers, accelerometer-type sensors, gyroscopes, speed meters, as well as sound signaling devices. In the development of the work, the steps of instrumentation of the tractor, data collection, implementation of the security system and validation of results were presented. As a result, proof of system operation was obtained, providing the operator with risk warnings regarding lateral tipping, warning of traction activation on slopes and slopes, warning for the activation of the parking brake and the activated power take-off. The operation of the system proved to be satisfactory, promoting safety warnings to the operator as designed. [resumo fornecido pelo autor]
