Work machine system

Abstract

A work machine system includes a lower travelling body, an upper slewing body slewably attached to an upper portion of the lower travelling body, an attachment having a bucket that is capable of holding a work object and is rotatably attached to the upper slewing body, and a controller. The controller controls the upper slewing body and the attachment so that the upper slewing body and the attachment perform a series of operations having a plurality of operation phases, detects an amount of the work object held by the bucket, sets a target amount that is a target of the amount of the work object, and specifies, as an abnormal phase, an operation phase in which the amount of the work object held by the bucket is smaller than the target amount.

1 . A work machine system comprising:
 a lower travelling body;   an upper slewing body slewably attached to an upper portion of the lower travelling body;   an attachment that has a tip attachment capable of holding a work object and is rotatably attached to the upper slewing body; and   a controller,   wherein the controller   controls the upper slewing body and the attachment so that the upper slewing body and the attachment perform a series of operations having a plurality of operation phases,   detects an amount of the work object held by the tip attachment,   sets a target amount that is a target of the amount of the work object, and   specifies, as an abnormal phase, an operation phase in which the amount of the work object held by the tip attachment is smaller than the target amount.   
     
     
         2 . The work machine system according to  claim 1 , wherein the controller specifies the abnormal phase based on whether each of an amount of the work object held by the tip attachment at a start point of the operation phase and an amount of the work object held by the tip attachment at an end point of the operation phase is smaller than the target amount. 
     
     
         3 . The work machine system according to  claim 2 , wherein the controller further specifies the abnormal phase based on whether an amount of the work object held by the tip attachment at an intermediate point between the start point and the end point is smaller than the target amount. 
     
     
         4 . The work machine system according to  claim 1 , wherein the controller sends a notification of the abnormal phase. 
     
     
         5 . The work machine system according to  claim 4 , further comprising
 a storage device that stores the abnormal phase specified by the controller while a predetermined period longer than a period during which the series of operations is performed once elapses,   wherein the controller sends the notification of the abnormal phase stored in the storage device when the predetermined period elapses.
