Subsequently, the control unit may receive update information from the remote management device 200 to complete the update, and report the update completion result to the remote management device 200 .

Subsequently, the remote management device 200 may issue a cold boot command for the control unit to the smart key module 300 , and the smart key module 300 may cut off power to the control unit. Accordingly, the control unit may not receive power for a predetermined standby time. During the waiting time, the storage battery provided in the control unit may be discharged, and the control unit may be driven in a more stable state.

In addition, the cold booting may include a built-in self test (BIST) function. The built-in self-test function can enhance the stability of the control unit by self-testing the internal memory and logic-related parts of the control unit.

In example embodiments, during the interruption time input by the user, the remote management apparatus 200 and the control unit may enter a power saving mode to minimize power and stop unnecessary operation. The construction machine 20 may enter a key-off state to stop unnecessary fuel consumption.

Then, it is possible to confirm the suspension of use of the construction machine (S230).

In example embodiments, the remote management device 200 may check the cessation of use of the construction machine 20 by consuming a minimum amount of power in the power saving mode. When the construction machine 20 is not in the use-stop state, the remote management device 200 may instruct the control unit to enter the power saving mode, and the construction machine 20 is in a key-off state. can be ordered to enter.

When it is determined that the update is not necessary, the remote management device 200 may enter the power saving mode again, and may instruct the control unit to enter the power saving mode. In addition, the remote management device 200 may instruct the construction machine 20 to enter a key-off state.

Then, it is possible to determine the progress of the update (S260).

In example embodiments, the remote management device 200 may determine the progress of the update and enter preparation for the progress of the update.

As described above, since software and firmware updates for the control unit are possible during the time period when the construction machine 20 is not operated, productivity can be improved, and the smart key module 300 starts up while software and firmware are updated. Since it can be controlled to disable key-off, it is possible to prevent the update from being incompletely terminated. In addition, since the control unit may be rebooted after the update is completed, it may be possible to create an optimal environment for the construction machine 20 .
