Analysis of Tractor Working Performace Based on CAN Bus

Liu Hongli, Wang Xi

Abstract

In order to accurately evaluate the performance of the tractor and the technical level of the operator, the CAN bus data analysis and storage system were used to acquire work parameter information of John Deere 7830 type tractor in certain operating width with returning cultivation method. ARCGIS, Matlab and Excel were used to visualize and analyze the data. The results showed that GPS receiver acquisition of latitude and longitude can be changed into plane coordinates with Gauss projection algorithm that can be more accurate to calculate the effective work area (1856hm2);reasonable coefficient of tractor torque was 27.01% of total output torque；engine load rate and fuel economy were relatively low and manual operation technology need to be improved; the actual speed of the tractor was 1700r/min which was 1600r/min more than rated speed at engine full load and power match was good. Based on the speed, torque and fuel consumption, the engine idling state and the effective operation time (2.75h) could be calculated.
