METHOD FOR MEASURING FORCES IN EARTH-MOVING MACHINES AND CONTROL THESE MACHINES, AND EARTH-MOVING MACHINE CONTAINING SUCH SYSTEM Russian patent published in 2023 - IPC E02F9/28 E02F9/24 E02F9/26 G08B21/18 

FIELD: measurement devices.

SUBSTANCE: proposed group of inventions is related to systems and methods for measuring forces in earth-moving machines. A system for measuring forces in earthmoving machines and controlling these machines, comprising a plurality of wear elements configured to be connected to a cutting edge of the earthmoving implements of the earthmoving machine; one or more sensors for measuring forces, each sensor of one or more sensors (20) being located in one wear element among a plurality of wear elements or between two wear elements among a plurality of wear elements; and a central control unit for processing the results of measurements made by one or more sensors to calculate the force withstood by the wear elements. The central control unit issues output commands based on at least one of the processed measurement results, whereby the output commands provide for at least one of the following operations: issuing a warning in form of at least one sensed signal and automatically reducing the breakout force of the machine if the processed values exceed the specified excessive force threshold; and providing a warning in form of at least one sensed signal and automatically increasing the breakout force if the processed values are less than a predetermined optimal force threshold value.

EFFECT: increase in efficiency, reduction of the risk of element failure, and an assessment of the service life of wear elements.
