AI Technical Summary
Existing excavators have low fuel supply efficiency and poor coordination among various actuators. In particular, when multiple actuators with different loads operate simultaneously, the operator's skill level is high and safety is difficult to guarantee.
By acquiring the ground slope and current working mode of the excavator's location, the opening of the hydraulic circuits supplying oil to the boom cylinder, bucket cylinder, stick cylinder, swing motor, and travel motor is adjusted. The ground slope and working mode are obtained using tilt sensors and stroke sensors, and the opening of the hydraulic circuits is controlled by an electro-proportional pressure reducing valve.
It improved the excavator's fuel supply efficiency, enhanced the coordination of various actuators, ensured the safety of the excavator's operation, and reduced flow and pressure losses.
