Other Abstract

In this paper, piezoelectric films are used as sensor sensitive materials. A grain cleaning loss rate monitoring device suitable for corn harvesting is designed. The impact sensor, signal processing circuit and mounting device are designed, and the corresponding processing algorithm is used to collect the impact signal. Firstly, under different experimental conditions of impact angle and height, the impact signal acquisition experiments of different sizes of corn kernels and impurities were carried out. The main characteristics of impact signal are also extracted. Secondly, the support vector machine is used for multi-classification. The model is trained by the support vector machine multi-classification algorithm and real-time classification is implemented on the monitoring device. And the classification model was validated using different corn varieties and moisture content. Then, under the conditions of different fan speed and cleaning screen opening degree, the relationship between the number of grains detected by the sensor and the total loss during the test time is obtained. And the real-time cleaning loss rate is calculated according to the grain flow value. Finally, the monitoring device was mounted on a 4YL-8 combine harvester and field trials were conducted. The results show that the average relative error of the monitoring device compared with manual detection is 12.98%, which can provide feedback for the control of the harvester.
