ABSTRACT:
The present invention is applied to a system comprised of large number of hydraulic excavators1deployed at construction sites and a base station16.Each hydraulic excavator1is provided with a storage unit (memory402), a control unit (CPU401) for executing the work operation and receiving as input a quantitative machine status relating to the work operation, and a communications device42.The base station16is provided with a communications device16a,a management server17for identifying the serial number of the hydraulic excavator1and transferring information, and a database18for storing various information. The control unit of the hydraulic excavator1and the management server17of the base station16transfer information. With this system configuration, the control unit measures the duration during which the quantitative machine status satisfies a predetermined condition and stores it in the storage unit and transmits the measurement data of the duration to the management server17of the base station16conditional on the power input key being in the off position, while the management server17receives the measurement data of the duration and calculates the cumulative operating time. Further, the quantitative machine status and various event data stored in the storage unit of the hydraulic excavator1are sent to the base station1,while the management server of the base station16stores the quantitative machine status and various event data in the database18by a predetermined format.
