The power arm 7 connects the equipment body 4 and the excavator head 8 to form an excavation system. The hydraulic system of the excavator head 8 is used to control the rotation speed of the excavator head 8, so that the system has a powerful excavation function. The controller 5 is set on the equipment body 4, connecting the hydraulic motor and the hydraulic system of the excavator head 8. The function of the controller 5 is to determine the real-time travel speed of the walking wheel 1 and the real-time rotation speed of the excavator head 8, so as to realize the integrated control of the entire system.

[0092] Furthermore, in this embodiment, by adjusting the walking speed and the rotation speed in real time, the system can operate efficiently in different working scenarios and improve work efficiency.

[0093] In some embodiments of the present application, a sensor component is also included;

[0118] When B<B4, the first data processing unit selects the fourth preset adjustment coefficient b4 to adjust the initial travel speed A once, and the initial travel speed after the adjustment is A*b4.

[0119] In some embodiments of the present application, the first data processing unit selects the i-th preset adjustment coefficient bi to adjust the initial travel speed A once, i=1, 2, 3, 4, and obtains the adjusted initial travel speed as A*bi, and further includes:

[0120] The initial travel speed A*bi after the adjustment is used as the adjusted travel speed C;

[0121] Obtaining the real-time vibration intensity data, denoted as D;

For different vibration intensity data, the system adopts a dynamic adjustment coefficient. Different vibration intensity thresholds and corresponding adjustment coefficients are preset, and dynamic adjustments are made according to the specific values ​​of the real-time vibration intensity data. The design of this dynamic adjustment coefficient makes the system more intelligent and flexible. By adjusting the travel speed according to the real-time data, the system can optimize performance, improve efficiency and stability in different situations. This dynamic adjustment strategy helps to reduce energy consumption, improve work efficiency, and extend equipment life.

[0139] In some embodiments of the present application, after the second data processing unit selects the i-th preset adjustment coefficient fi to adjust the initial rotation speed E once, i=1, 2, 3, 4, and obtains the adjusted initial rotation speed as E*fi, it further includes:

[0140] Obtain the real-time acceleration data, recorded as G;

[0141] A first preset acceleration threshold value G1, a second preset acceleration threshold value G2, a third preset acceleration threshold value G3, and a fourth preset acceleration threshold value G4 are preset, and G1>G2>G3>G4; a first preset adjustment coefficient g1, a second preset adjustment coefficient g2, a third preset adjustment coefficient g3, and a fourth preset adjustment coefficient g4 are preset, and 1.1>g1>g2>1>g3>g4>0.9;

[0142] When G≥G1, the second data processing unit selects the first preset adjustment coefficient g1 to perform a second adjustment on the initial rotation speed E*fi after the first adjustment, and the initial rotation speed after the second adjustment is E*fi*g1;

[0143] When G1>G≥G2, the second data processing unit selects the second preset adjustment coefficient g2 to perform a second adjustment on the initial rotation speed E*fi after the first adjustment, and the initial rotation speed after the second adjustment is E*fi*g2;

[0144] When G2>G≥G3, the second data processing unit selects the third preset adjustment coefficient g3 to perform a second adjustment on the initial rotation speed E*fi after the first adjustment, and the initial rotation speed after the second adjustment is E*fi*g3;

[0145] When G3>G≥G4, the second data processing unit selects the fourth preset adjustment coefficient g4 to perform a second adjustment on the initial rotation speed E*fi after the first adjustment, and the initial rotation speed after the second adjustment is E*fi*g4.

[0146] In some embodiments of the present application, the second data processing unit selects the i-th preset adjustment coefficient gi to perform a second adjustment on the initial rotation speed E*fi after the first adjustment, i=1, 2, 3, 4, and obtains the initial rotation speed after the second adjustment as E*fi*gi, and further includes:

[0147] The initial rotation speed E*fi*gi after the second adjustment is used as the real-time rotation speed.

[0148] It can be understood that in this embodiment, by presetting different torque thresholds and corresponding adjustment coefficients, the system adopts a multi-level torque adjustment strategy. According to the different numerical ranges of real-time torque data, the system selects different preset adjustment coefficients for primary adjustment, so that the system can be adjusted in a targeted manner under different workloads. After the first adjustment, the system introduces real-time acceleration data for secondary adjustment. By setting different acceleration thresholds and corresponding adjustment coefficients, the system can dynamically make secondary adjustments based on the acceleration data to better adapt to different motion states and environments. The multi-level, dynamic adjustment strategy helps to optimize the rotation speed and improve the stability and responsiveness of the system. By setting different preset torque thresholds and acceleration thresholds, and selecting the corresponding adjustment coefficients according to actual conditions, the system can more flexibly adapt to various working conditions and requirements, making the system more intelligent and robust.
