Abstract

A work machine control system includes: an acquisition processing unit; a determination processing unit; and an alarm processing unit. The acquisition processing unit acquires a detection result of an object around a machine body of a work machine. The determination processing unit determines whether the work machine is operable or inoperable. The alarm processing unit outputs an alarm. The alarm processing unit prohibits the alarm's outputting when it is determined, after the first situation, that the work machine is operable. Further, the alarm processing unit outputs the alarm under the first situation, and continues the alarm's outputting when it is determined, after the first situation, that the work machine is operable. The first situation is defined as a situation in which the work machine is determined to be inoperable, and in which the detection result meets a given condition.

Claims (48)

1. A work machine control system comprising:

an acquisition processing unit that acquires a detection result of an object around a machine body of a work machine;

a determination processing unit that determines whether the work machine is operable or inoperable; and

an alarm processing unit that outputs an alarm,

wherein

the alarm processing unit, in a first situation defined as a situation in which the work machine is determined to be inoperable and in which the detection result meets a given condition,

prohibits the alarm's outputting when it is determined, after the first situation, that the work machine is operable.

2. The work machine control system according to claim 1 , wherein

the given condition includes the object being present in a monitored area around the work machine.

3. The work machine control system according to claim 1 , wherein

the alarm processing unit performs the alarm's outputting under the first situation.

4. The work machine control system according to claim 1 , wherein

the determination processing unit determines, when a gate lock lever of the work machine is locked or an ignition of the work machine is off, that the work machine is inoperable, and determines, when the gate lock lever is unlocked and the ignition is on, that the work machine is operable.

5. The work machine control system according to claim 1 , wherein

the alarm processing unit, when it is determined, after the first situation, that the work machine is operable, presents information in a mode different from the alarm.

6. The work machine control system according to claim 1 , wherein

the determination processing unit is capable of determining that the work machine is operable, when at least a user operates the work machine after the first situation.

7. A work machine, comprising:

the work machine control system according to claim 1 ; and

the machine body.

8. A work machine control method comprising:

acquiring a detection result of an object around a machine body of a work machine;

determining whether the work machine is operable or inoperable; and

in a first situation defined as a situation in which the work machine is determined to be inoperable and in which the detection result meets a given condition, prohibiting the alarm's outputting when it is determined, after the first situation, that the work machine is operable.

9. A work machine control program for causing one or more processors to execute the work machine control method according to claim 8 .

10. A work machine control system comprising:

an acquisition processing unit that acquires a detection result of an object around a machine body of a work machine;

a determination processing unit that determines whether the work machine is operable or inoperable; and

an alarm processing unit that outputs an alarm, wherein

the alarm processing unit, in a first situation defined as a situation in which the work machine is determined to be inoperable and in which the detection result meets a given condition, outputs the alarm under the first situation, and continues the alarm's outputting when it is determined, after the first situation, that the work machine is operable.

11. The work machine control system according to claim 10 , wherein

the given condition includes the object being present in a monitored area around the work machine.

12. The work machine control system according to claim 10 , wherein

the determination processing unit determines, when a gate lock lever of the work machine is locked or an ignition of the work machine is off, that the work machine is inoperable, and determines, when the gate lock lever is unlocked and the ignition is on, that the work machine is operable.

13. The work machine control system according to claim 10 , wherein

the alarm processing unit, in a second situation defined as a situation in which the work machine is determined to be operable and in which the detection result meets the given condition, outputs the alarm even under the second situation.

14. The work machine control system according to claim 13 , wherein

the alarm processing unit continues the alarm's outputting when it is determined, after the second situation, that the work machine is inoperable.

15. The work machine control system according to claim 10 , wherein

the determination processing unit is capable of determining that the work machine is operable, when at least a user operates the work machine after the first situation.

16. A work machine, comprising:

the work machine control system according to claim 10 ; and

the machine body.

17. A work machine control method comprising:

acquiring a detection result of an object around a machine body of a work machine;

determining whether the work machine is operable or inoperable; and

in a first situation defined as a situation in which the work machine is determined to be inoperable and in which the detection result meets a given condition, outputting an alarm under the first situation, and continuing the alarm's outputting when it is determined, after the first situation, that the work machine is operable.

18. A work machine control program for causing one or more processors to execute the work machine control method according to claim 17 .
