Abstract

A work machine includes a controller having a first storage unit that can store work machine information and rewrite the stored work machine information, and a processing unit that collects the work machine information, and stores at least one kind of the work machine information in the first storage unit when trigger information for causing the first storage unit to start storing the work machine information occurs. The controller can change from an outside at least one of the number of data prior to a trigger of the work machine information collected by the processing unit before the trigger information, the number of data subsequent to the trigger of the work machine information collected by the processing unit after the trigger information, and a time interval during which the work machine information is collected.

Claims

1. A work machine comprising a controller including:

a storage unit capable of storing work machine information as information on the work machine; and

a processing unit configured to collect the work machine information and to cause at least one kind of the work machine information to be stored in the storage unit when trigger information for causing the storage unit to start storing the work machine information occurs, wherein

at least one of the number of data prior to a trigger of the work machine information collected by the processing unit before the trigger information, the number of data subsequent to the trigger of the work machine information collected by the processing unit after the trigger information, and a time interval during which the work machine information is collected is changeable from an outside of the controller.

2. The work machine according to claim 1, wherein the kind of the work machine information is changeable.

3. The work machine according to claim 1, wherein

the storage unit stores definition information where the number of data prior to the trigger, the number of data subsequent to the trigger, and the time interval, which are to be stored, are described, and

the processing unit is configured to collect the work machine information in accordance with the number of data prior to the trigger, the number of data subsequent to the trigger, and the time interval, which are described in the definition information.

4. The work machine according to claim 2, wherein

the storage unit stores definition information where the number of data prior to the trigger, the number of data subsequent to the trigger, the time interval, and the kind of the work machine information, which are to be stored, are described, and

the processing unit saves the collected work machine information in the storage unit in accordance with the number of data prior to the trigger, the number of data subsequent to the trigger, the time interval, and the kind of the work machine information, which are described in the definition information.

5. The work machine according to claim 3, wherein the definition information is rewritten from the outside of the controller to change at least one of the number of data prior to the trigger, the number of data subsequent to the trigger, and the time interval.

6. The work machine according to claim 4, wherein the definition information is rewritten from the outside of the controller to change at least one of the number of data prior to the trigger, the number of data subsequent to the trigger, the time interval, and the kind of the work machine information.

7. The work machine according to claim 1, further comprising a plurality of the controllers each being able to change the number of data prior to the trigger, the number of data subsequent to the trigger, and the time interval individually.

8. The work machine according to claim 2, further comprising a plurality of the controllers each being able to change the number of data prior to the trigger, the number of data subsequent to the trigger, the time interval, and the kind of the work machine information individually.

9. The work machine according to claim 3, further comprising a communication unit configured to communicate with the outside of the controller, wherein the definition information is rewritable by wireless communication via the communication unit from the outside of the controller.

14. The work machine according to claim 5, wherein after the definition information stored in the storage unit is rewritten, when a key switch of the work machine is turned on, the rewritten definition information becomes effective.

10. A work machine comprising a controller including:

a storage unit capable of storing work machine information as information on the work machine; and

a processing unit configured to collect the work machine information, and causing at least one kind of the work machine information to be stored in the storage unit based on trigger information for causing the storage unit to start saving the work machine information, wherein

the processing unit is configured to cause the work machine information collected in accordance with definition information where at least one of the number of data prior to a trigger of the work machine information collected by the processing unit before the trigger information, the number of data subsequent to the trigger of the work machine information collected by the processing unit after the trigger information, and a time interval during which the work machine information is collected is described and stored in the storage unit, and is changeable from an outside of the controller, to be stored in the storage unit, and

the storage unit is different from a storage unit where an instruction to cause the processing unit to execute an operation to save the work machine information in the storage unit is saved.

11. The work machine according to claim 10, wherein the kind of the work machine is changeable.

12. The work machine according to claim 11, wherein a plurality of kinds of the definition information is stored in the storage unit.

13. The work machine according to claim 12, wherein the plurality of kinds of the definition information is individually changeable from the outside of the controller.
