| description | A monitoring and diagnosing device for a working machine configured is provided such that it can perform diagnosis appropriately and prevent erroneous determination even when strong similarity appears between input signals under a normal operational state and an abnormal operational state. The monitoring and diagnosing device comprises: a classification information storage section (102) in which reference classification information is stored; a frequency information storage section (105) in which reference frequency information is stored; a first data classifier section (101) which reads out the reference classification information from the classification information storage section, compares the operational data, detected by the plurality of sensors and inputted in time sequence, with the reference classification information to thereby classify the operational data, and then generates operational data classification information; a frequency comparator section (104) which compiles the operational data classification information, generates operational data frequency information by adding, to the operational data classification information, appearance frequency information for each of the classifications of the operational data, reads out the reference frequency information from the frequency information storage section, and then generates operational data frequency comparison information by comparing the operational data frequency information with the reference frequency information; and an abnormality diagnosing section (103) which performs an abnormality diagnosis upon the working machine by use of the operational data classification information and the operational data frequency comparison information. |
