In one aspect, a system for detecting tripping of ground engaging tools on an agricultural implement may include a ground engaging tool coupled to an implement frame. Furthermore, the system may include a motion sensor installed on the implement frame, with the motion sensor configured to capture data indicative of motion of the implement frame. Moreover, the system may include a controller configured to monitor the motion of the implement frame based on the data received from the motion sensor. In addition, the controller may be further configured to determine when the ground engaging tool has tripped based on the monitored motion.

A display device for a shovel that includes an attachment including a boom, an arm, and an end attachment includes an operation analysis start input part and an operation analysis check input part. The operation analysis start input part is configured to be operated to start an operation analysis of the shovel and store the history of the operation analysis. The operation analysis check input part is configured to be operated to display the result of the operation analysis.

A working machine includes an undercarriage supported by first and second ground engaging units powered by first and second drive units, a main frame supported by the undercarriage, a first sensor configured to sense an orientation and relative angular motion of the main frame with respect to the undercarriage, a second sensor configured to sense an orientation and relative angular motion of the main frame in an external reference frame independent of the undercarriage, and a controller functionally linked to the first and second sensors. The controller is configured to receive commands corresponding to an intended movement of the first and second ground engaging units, and generate control signals to the first and second drive units to achieve or maintain the intended movement taking into account a detected orientation of the main frame relative to the undercarriage and a detected orientation of the main frame in the external reference frame.

A work system includes an operation device that transmits an operation signal, a work machine that operates on the basis of the operation signal, and a transport vehicle that outputs a traveling control signal in a case where a fault in communication between the operation device and the work machine occurs.

A coupler cylinder is driven between a locked state and an unlocked state of a bucket by being supplied with hydraulic oil. A main pump supplies the hydraulic oil to the coupler cylinder. A pressure increasing valve controls the supply of the hydraulic oil to the coupler cylinder. A controller controls drive of the pressure increasing valve. The controller instructs the pressure increasing valve to stop the supply of the hydraulic oil to the coupler cylinder based on pressure in an oil passage between the main pump and the coupler cylinder.

In some implementations, a controller may obtain, during an event, pressure data regarding an amount of pressure of fluid associated with a component of the machine. The controller may obtain, during the event, flow data regarding a flow of the fluid associated with the component of the machine. The controller may determine, based on the pressure data and the flow data, an amount of wear of a track of the machine. The controller may perform an action based on the amount of wear of the track of the machine.

There is provided a technology capable of improving work efficiency of a work machine that is remotely operated by an operator through a remote operation apparatus. If a first condition is satisfied, that is, if an engine stop instruction for a work machine 40 is made through a remote input interface 21 of the remote operation apparatus 20, operation of an engine 460 is stopped in principle, but the operation of the engine 460 is exceptionally not stopped. Specifically, when an operator does not exist at a specified position at the time of operating a remote operation mechanism 211 in the remote operation apparatus 20, the operation of the engine 460 is stopped. On the other hand, when the operator exists at the specified position, the operation of the engine 460 is continued without being stopped even if an engine operation instruction is made.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cabin mounted on the upper turning body, an operator's seat installed in the cabin, an operating lever installed in the cabin, and a switch installed in the cabin, where the switch is disabled when the operating lever is operated.

A construction assist system that assists construction with a shovel includes a hardware processor configured to simulate the motion of the shovel in a virtual environment that is set based on the work environment of the shovel.

Disclosed is a system for status diagnosis of construction machinery. The system for status diagnosis of the construction machinery to determine the abnormality of the construction machinery may include a sensor unit including at least one or more oil property sensors for detecting oil property information and at least one or more equipment sensors for detecting operating status information, a control unit configured to determine a basic status of the construction machinery through the oil property information and determine an overall status of the construction machinery by reflecting the operating status information of the construction machinery based on the basic status of the construction machinery, and a display unit configured to display a notification according to the determination of the control unit.
