摘  要：
为了准确评价拖拉机作业性能及操作人员的技术水平,利用拖拉机CAN总线数据解析存储系统,获得John Deere 7830型拖拉机在一定作业幅宽内,以回耕法进行整地时的作业参数信息,利用ARCGIS、Matlab与Excel对数据进行可视化处理并对其进行分析。结果表明,利用高斯投影算法将GPS接收机采集到的经纬度转换成平面坐标,能够更加精确地计算出有效作业面积;拖拉机扭矩合理系数占总输出扭矩的27.01%,发动机负荷率偏低,燃油经济性差,操作手作业技术有待改进;拖拉机发动机作业实际转速为1 700 r/min,超过发动机满负荷标定转速(1 600 r/min),动力匹配性良好;通过转速、扭矩和油耗可以判断发动机怠速状态,从而计算出有效的作业时间。

摘  要：
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 was1 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.
