Abstract

An operation state management system for a construction machine includes a management apparatus configured to manage an operation state of the construction machine by communicating with the construction machine and a construction machine including a cumulative value storage device configured to store a cumulative value in which an amount of operation of the construction machine is accumulated and have an adjustment function to the stored cumulative value, an adjustment existence determining unit configured to determine whether the cumulative value stored in the cumulative value storage device has been adjusted, and a communication terminal apparatus configured to communicate with the management apparatus and transmit adjustment information indicating that at least the cumulative value has been adjusted to the management apparatus when the adjustment existence determining unit has determined that the adjustment has been performed.

Claims

1. A construction machine comprising:

a cumulative value storage device configured to store a cumulative value in which an amount of operation of the construction machine is accumulated and have an adjustment function to the stored cumulative value, the cumulative value storage device comprising a memory;

a user input device for adjusting the cumulative value by rewriting the cumulative value stored in the cumulative value storage device at a present moment;

an adjustment existence determining unit configured to determine, based on the cumulative value rewritten by the user input device, whether the cumulative value has been adjusted, the adjustment existence determining unit comprising a processor; and

a communication terminal configured to communicate with a management apparatus outside the construction machine and transmit adjustment information indicating that at least the cumulative value has been adjusted to the management apparatus when the adjustment existence determining unit has determined that the adjustment has been performed,

wherein when the cumulative value storage device obtains a correction request instruction to correct the cumulative value to a value specified by the management apparatus from the management apparatus, the cumulative value storage device corrects the cumulative value stored in the cumulative value storage device to the specified value, and

wherein after the cumulative value storage device obtains the correction request instruction, the cumulative value storage device corrects the cumulative value to the specified value after a key switch of the construction machine has been turned OFF and turned ON again.

2. The construction machine according to claim 1, wherein

the communication terminal further transmits the number of times of the adjustment or a time when the adjustment has been performed.

3. The construction machine according to claim 1, wherein

the adjustment information is at least one of the cumulative value after the adjustment or a difference between a value after the cumulative value has been adjusted and a value before the cumulative value is adjusted.

4. The construction machine according to claim 1, wherein

the communication terminal includes a storage unit configured to store information on failures generated in the construction machine and makes the storage unit store at least the adjustment information.

5. The construction machine according to claim 1, wherein

when the cumulative value storage device obtains a limitation request instruction to limit the adjustment function to the cumulative value from the management apparatus, the cumulative value storage device turns off the adjustment function to the cumulative value.

6. The construction machine according to claim 1, wherein

when the cumulative value storage device obtains a limitation request instruction to limit the number of times to adjust the cumulative value from the management apparatus, the cumulative value storage device limits the number of times to adjust the cumulative value.

7. A construction machine comprising:

a cumulative value storage device configured to store a cumulative value in which an amount of operation of the construction machine is accumulated and have an adjustment function to the stored cumulative value, the cumulative value storage device comprising a memory;

a user input device for adjusting the cumulative value by rewriting the cumulative value stored in the cumulative value storage device at a present moment; and

a communication terminal configured to communicate with a management apparatus outside the construction machine, wherein

when the cumulative value storage device obtains a limitation request instruction to limit the adjustment function to the cumulative value that is performed using the user input device from the management apparatus, the cumulative value storage device turns off the adjustment function to the cumulative value.

8. A construction machine comprising:

a cumulative value storage device configured to store a cumulative value in which an amount of operation of the construction machine is accumulated and have an adjustment function to the stored cumulative value, the cumulative value storage device comprising a memory;

a user input device for adjusting the cumulative value by rewriting the cumulative value stored in the cumulative value storage device at a present moment; and

a communication terminal configured to communicate with a management apparatus outside the construction machine, wherein

when the cumulative value storage device obtains a correction request instruction to correct the cumulative value rewritten by the user input device to a value specified by the management apparatus from the management apparatus, the cumulative value storage device corrects the cumulative value stored in the cumulative value storage device to the specified value.
