Description
- The increase in the efficiency of agricultural machinery is a theme that attracted the attention and investments of the industrial and research community. In addition, in a global market, where the prices of agricultural commodities are so volatile and the prices of the inputs increase, farmers and agricultural contractors struggle to obtain at the end of the agricultural season a consolidated profit. For these reasons, it is important to carefully plan the usage of combine harvesters, to reduce the unproductive time and the input usage such as the fuel, that at the end of the harvesting season could increase costs. This study aims to develop an algorithm able to automatically identify and evaluate the time spent by the combines in each of the identified activities, identify the field boundaries of the harvested fields and perform a performance evaluation. To be able to develop the algorithm, during the harvesting seasons of 2020 and 2022, two combine harvesters operating in real-world conditions in Bologna’s Province were monitored. The data necessary to perform the analysis were acquired as CANBUS data and processed by using the MATLAB ® suite. The results obtained from this analysis show that the monitored combines have spent over 60% of the time performing harvesting activities, 13% of the time idling at the field, 10% performing headland turn, the 3% and 4% of the time respectively in transport on the field and road and 2% of the time in unloading. In addition, the performance of the monitored combines resulted similarly to the performance reported in other studies.
