This hydraulic excavator serves as a construction machine and is equipped with: a monitoring unit for monitoring the periphery around the construction machine; and a control unit for controlling the execution of a construction machine operation restriction based on the monitoring results of the monitoring unit according to the operating mode of the construction machine. The control unit executes the operation restriction based on the monitoring results when the operation mode is a normal mode which is not a specific mode, and stops execution of the operation restriction based on the monitoring results when the operation mode is the specific mode.

Construction machine

A work vehicle includes a monitoring device which monitors the surroundings of the work vehicle; an alarm device which outputs an alarm on the basis of a monitoring result of the monitoring device; a posture detection unit which detects whether an operator sits on an operation seat of the work vehicle and is in an operation posture for operating the work vehicle; and a control unit which controls the alarm device on the basis of the result of detection by the posture detection unit. Based on detection by the posture detection unit that the operator is in the operation posture, the control unit causes the alarm device to output an alarm based on the monitoring result of the monitoring device, and based on detection by the posture detection unit that the operation posture of the operator is released, the control unit causes the alarm device to stop outputting the alarm based on the monitoring result of the monitoring device.

Work vehicle

The method for controlling the work machine includes executing a restraint process of restraining an operation of the work machine based on a detection result of a detector detecting a detection target in a monitoring area around the work machine, performing switching between an enabled state and a disabled state of a function associated with the restraint process, and displaying a display screen including restraint state information indicating whether the function associated with the restraint process is enabled or disabled, on a display device.

Method for controlling work machine, work machine control program, and work machine control system

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.
