Abstract
A work implement is attached to a work machine body. A plurality of strain sensors are arranged along a portion of the work implement that intersects with a virtual plane. A controller estimates a load state of the working implement based on strain data detected by the plurality of strain sensors.
Claims15
A system comprising a work machine, the system comprising:
- a work machine body;
- a work implement attached to the work machine body;
- a plurality of strain sensors arranged along a portion of the work implement that intersects with a virtual plane;
- and
- a controller configured to estimate a load state of the work implement based on strain data detected by the plurality of strain sensors.
A system comprising a work machine, the system comprising:
- a work machine body;
- a work implement attached to the work machine body;
- a plurality of strain sensors arranged at at least four locations of the work implement;
- and
- a controller configured to estimate a load state of the work implement based on strain data of the at least four locations detected by the plurality of strain sensors.
A system comprising a work machine, the system comprising:
- a work machine body;
- a work implement attached to the work machine body;
- a plurality of strain sensors arranged along a portion of the work implement that intersects with a virtual plane;
- a display device;
- and
- a controller configured to determine a load mode of the work implement based on strain data detected by the plurality of strain sensors, estimate a stress at any location of the work implement, and display, on the display device, when the stress estimated is greater than a predetermined threshold value, a load mode and a portion of the work implement when the stress estimated is greater than the predetermined threshold value.
