摘要： Provided is an abnormality detecting device for a construction machine that can estimate an abnormality occurring to a component (engine, pump, etc.) of the construction machine based on the relationship among a plurality of pieces of sensor information and thereby prevent machine failure. A correlation coefficient calculation unit 102 calculates correlation coefficients between time-series sensor values acquired by a plurality of sensors 101. A correlation coefficient comparison unit 103 compares the correlation coefficients and calculates the degree of difference between each correlation coefficient and other correlation coefficients. An abnormality judgment unit 104 judges that an abnormality has occurred to a part related to a sensor when the degree of difference calculated in regard to the sensor exceeds a preset value.

摘要： 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.

摘要： Provided is an operation data collection device for work machines that ensures savings in storage capacity while at the same time preserving important operation data recorded at the time of a faulty condition even when the frequency of access diminishes. The operation data collection device for work machines includes a plurality of sensors attached to a work machine to receive measurement data of the sensors as operation data and record the operation data in an operation data storage section. The operation data collection device for work machines further includes: a communication processing section that transmits the operation data stored in the operation data storage section to an external server in response to a download request from the external server; an access history management section that manages a download status of the operation data recorded in the operation data storage section, through the download request from the external server and the transmission of the operation data to the external server; and a recorded data change processing section that changes a condition for recording the operation data in the operation data storage section in accordance with the download status of the operation data acquired by the access history management section.
