Abstract

This invention proposes a one-button wireless control method for efficient operation of large excavators. First, the excavator's hydraulic system is electronically modified. Then, a wireless control device is built to enable single-step control of each component's movements. Next, the high-frequency, repetitive, sequential actions of the excavator are analyzed. Finally, based on a "sensor-control" approach, one-button control of these sequential actions is achieved. The device includes a remote controller, a wireless transmission module, a signal processing module, a current generation module, and multiple solenoid valves, enabling wireless control of both single-step and sequential actions. This method integrates real-time perception and precise control of the excavator's operating components, achieving efficient and accurate one-button sequential control and improving the excavator's operational efficiency.
