Diagnostic device for work machine
This diagnostic device for a work machine is provided with: a display device that displays the operation steps of the work machine; a controller that obtains, from a sensor that detects the state quantity of the work machine, the state quantity during a period in which the work machine is operated in accordance with the operation step, and diagnoses the working performance of the work machine on the basis of the state quantity of the work machine; and an output device that outputs a diagnosis result diagnosed by the controller. The controller measures, on the basis of the plurality of state quantities detected by the sensor, an operation performance value indicating a prescribed operation performance of the work machine and a plurality of cause parameters that affect the operation performance value, and determines, on the basis of the measured values of the plurality of cause parameters and a reference value that is predetermined for each of the plurality of cause parameters, the operation performance value of the work machine based on the measured values of the plurality of cause parameters. The degree of influence imposed on the operating performance value by each of the plurality of factor parameters is calculated, so that the operating performance value and the degree of influence are output by the output device.
作业机械的诊断装置具有：显示装置，其显示作业机械的操作步骤；控制器，其从检测作业机械的状态量的传感器获得作业机械按照操作步骤被操作的期间内的状态量，并基于作业机械的状态量来诊断作业机械的工作性能；和输出装置，其将由控制器诊断出的诊断结果输出。控制器基于由传感器检测到的多个状态量来测定表示作业机械的规定的工作性能的工作性能值、和对工作性能值产生影响的多个要因参数，基于多个要因参数的测定值、和针对多个要因参数的每一个预先确定的基准值，来运算多个要因参数的每一个对工作性能值付与的影响程度，使工作性能值以及影响程度由输出装置输出。
