1. A method of detection of the actual operating time of machinery characterized by being applied to a system including:

  • machinery each provided with a storage unit, a control unit receiving as input a quantitative machine status for work operations, and a first communications device enabling communication with an outside unit present at a distant location and deployed at a construction site; and

    a base station provided with a second communications device enabling communication with an outside unit present at a distant location, a center server for identifying a serial number of machinery and transferring information with said control unit, and a database managed by said center server and storing information for each model of said machinery and information relating to the operation for each machinery;

    wherein said control unit of said machinery and said center server of said base station are configured to be able to transfer information with each other through said communications devices and a communication line;

    wherein said control unit measures the duration where a quantitative machine status satisfies a predetermined condition and stores it in the storage unit and transmits the measurement data of said duration to said center server of said base station; and

    said center server receives the measurement data of said duration and calculates the cumulative operating time.
