Abstract

The invention discloses a method for judging the working state of agricultural machinery based on GPS and engine data, which is characterized in that it includes a method S1 of training a discrimination model, a method S2 of calling the model for prediction, and a method S3 of refining the start and end time of the working state; S1) The method for training the discriminant model comprises the following steps: S11) Acquiring vehicle work data: collecting GPS data and engine ECU data of different states of the agricultural machinery in operation state, field transfer state and idling state, the GPS data includes agricultural machinery instantaneous speed, steering Angle, the present invention collects the ECU and GPS data of different operating states of agricultural machinery, marks each data, uses the marked data to train the discrimination model, and then uses the model to distinguish the operating state of agricultural machinery; it does not rely on the GPS density of agricultural machinery to avoid changes in GPS density The discriminative error brought about; train the judgment model for the situation of missing data, and avoid the loss of accuracy of the judgment result caused by missing data.

Description

technical field [0001] The invention relates to the technical field of intelligent agricultural machinery equipment, in particular to a method for judging the operating state of agricultural machinery based on GPS and engine data. Background technique [0002] The modern agricultural system has changed from manpower and animal power to mechanical power. The biggest difference is whether the power form is mechanized. However, further improving the production efficiency of agricultural mechanization requires intensive cultivation, precise control and precise use of mechanical power. The operating status of agricultural machinery is closely related to the failure of agricultural machinery, the efficiency of the transmission system, and the quality of operation. Accurate identification of the operating status of agricultural machinery is of great significance to the identification of agricultural machinery faults, the improvement of the agricultural machinery transmission syste...
