摘　　要：为了实现对装载机循环工况中工作阶段的识别,以装载机的动臂缸无杆腔压力、转斗缸无杆腔压力、动臂缸位移、转斗缸位移以及前进挡和倒退挡为识别信号,在多个循环作业过程中提取数据,与构建的工作阶段标准特征向量作Manhattan距离运算,对各工作阶段进行自动识别分类,依据装载机作业循环逻辑顺序,引入校正规则对识别结果进行校正。试验结果表明,该方法对装载机随机工作阶段的识别准确率达到98.32%,对完整循环工况的工作阶段识别率为97.24%,通过校正规则,可以将识别率提高到100%。为装载机适应工作阶段载荷的变化而动态调节发动机控制提供了基础。In order to realize the identification of the working phases in the loader driving cycle,the pressure of the rodless chamber of the boom cylinder,the pressure of the rodless chamber of the bucket cylinder,the displacement of the boom cylinder,the displacement of the bucket cylinder and the forward and reverse gears of the loader are used as the identification signals,the data is extracted during several cycles of operation,and the Manhattan distance operation is performed with the standard feature vector of the working phases constructed to automatically identify and classify each working phase.Based on the logical sequence of loader operation cycles,correction rules are introduced to correct the identification results.The test results show that the method has an accuracy of98.32% in identifying the random working phases of the loader and an identification rate of 97.24% in identifying the working phases of the full driving cycle,and the identification rate can be increased to 100% through the correction rules.This provides a basis for dynamically adjusting the engine control for the loader to adapt to load changes in the working phases.
