Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0031] Example 1: See Figures 1 to 2 This is a schematic diagram of the various structures of the present invention. The data acquisition module is used to acquire signals and includes a left handle module 18, a right handle module 19, a fan switch 1, a quick-change switch 2, and a seat belt switch 4. The data acquisition module is connected to the auxiliary data processing module 8 via electrical signals.
[0032] Auxiliary data processing module 8 is a neural network processor that supports multi-source data fusion and AI algorithm optimization. It receives and processes data and outputs control commands. Auxiliary data processing module 8 is connected to a diagnostic interface 17, which is used for program flashing and fault diagnosis of auxiliary data processing module 8.
[0033] The machine controller 20 is the control center of the excavator. It can collect data of the whole vehicle, including left travel, right travel, boom lifting or lowering, stick lifting or lowering, and pressure signal data of attachment movement. The controller and the auxiliary data processing module 8 are connected via CAN communication.
[0034] The execution module receives and executes control commands, including a rear camera 5, a green safety warning light 6, a buzzer 7, an audible and visual alarm light 9, an oil diffuser fan module 10, a double solenoid valve A11, a double solenoid valve B12, a double solenoid valve C13, a double solenoid valve D14, a double solenoid valve E15, and a solenoid valve F16. The execution module is connected to the auxiliary data processing module 8 via electrical signals.

Through the collaboration of hardware and software, the device status is monitored and displayed in real time. The device mode can be switched and the function can be selected through human-computer interaction.
[0036] Specifically, the machine controller 20 collects left travel, right travel, boom lifting or lowering, stick lifting or lowering, and attachment action pressure signal data, which can be fed back to the auxiliary data processing module 8 via CAN communication. After processing the data, the auxiliary data processing module 8 outputs instructions to the audible and visual alarm light 9. The operator interacts with the machine through the data display module 3 to set whether the audible and visual alarm light 9 should be activated when an action is performed. When the audible and visual alarm light 9 for the corresponding action is set to "on", the auxiliary data processing module 8 outputs instructions to the audible and visual alarm light 9 when the action is performed, and the audible and visual alarm light 9 is activated. Different instructions are executed by the audible and visual alarm light based on the action pressure signal data, and these settings can be configured through the data display module 3.
[0037] Specifically, when quick-change switch 2 is pressed, it sends an electrical signal to auxiliary data processing module 8. Auxiliary data processing module 8 outputs data to data display module 3, which displays "Quick-change mode enabled." Auxiliary data processing module 8 outputs a signal to buzzer 7, which sounds an alarm. Auxiliary data processing module 8 also outputs a command to solenoid valve F16 to cut off the attachment oil circuit, allowing the operator to replace the attachment. After replacement, the operator closes quick-change switch 2, and auxiliary data processing module 8 sends a command to stop buzzer 7 from sounding the alarm. Solenoid valve F16 connects to the attachment oil circuit. Solenoid valve F16 is located on the attachment actuation oil circuit and cuts off the attachment oil circuit during attachment replacement to facilitate the replacement process.
[0038] Specifically, the whole machine controller 20 receives the hydraulic oil temperature signal and outputs the signal to the auxiliary data processing module 8. When the oil temperature is higher than the set value, the auxiliary data processing module 8 transmits the data to the data display module 3. The data display module 3 displays an overheating warning command. The operator turns on the fan switch 1, which transmits the signal to the auxiliary data processing module 8. The auxiliary data processing module 8 receives the signal and transmits it to the oil cooling fan module 10. The oil cooling fan module 10 rotates to dissipate heat. The auxiliary data processing module 8 controls the speed of the oil cooling fan module 10 so that the oil temperature is proportional to the speed, achieving adaptive cooling and reducing energy consumption.
[0039] Specifically, when the driver is not wearing a seatbelt in the vehicle, the seatbelt switch 4 outputs data to the auxiliary data processing module 8, the auxiliary data processing module 8 outputs instructions to the data display module 3, and the data display module 3 displays text reminding the driver to fasten the seatbelt. When the driver is wearing a seatbelt in the vehicle, the seatbelt switch 4 outputs data to the auxiliary data processing module 8, the auxiliary data processing module 8 outputs instructions to the green safety warning light 6, reminding outsiders that there is a driver in the driver's cab to prevent accidents.
[0040] Specifically, the machine controller 20 collects the left and right travel motion pressure signal data, which can be fed back to the auxiliary data processing module 8 via CAN communication. When the excavator is reversing, the auxiliary data processing module 8 outputs a command to the rear camera 5. The rear camera 5 works and transmits data to the auxiliary data processing module 8. The auxiliary data processing module 8 transmits the data to the data display module 3. The data display module 3 displays the image interface collected by the rear camera 5. When the operator is reversing, the data display module 3 automatically displays the image of the rear camera 5.
[0041] Specifically, the double solenoid valve A11 is a bidirectional voltage-type solenoid valve for switching. As the execution system for the quick-change function, when the operator presses the quick-change switch 2, the quick-change switch 2 transmits a signal to the auxiliary data processing module 8 for data processing. The auxiliary data processing module 8 outputs a command to the double solenoid valve A11, which performs bidirectional oil circuit switching to realize the disassembly and installation of the stick end attachment. When the command is received, the hydraulic system controls the attachment installation oil circuit and the disassembly oil circuit to realize the disassembly and installation of the stick end attachment.
[0042] The excavator's stick end is equipped with a quick-connect coupling, also called a fast connector. This coupling primarily improves the efficiency of bucket replacement with other working components such as the bucket and ripper during operation. There are two types: hydraulic and mechanical. The excavator described in this application uses a hydraulic quick-connect coupling. A dual solenoid valve A11 performs bidirectional oil circuit switching, thereby enabling the disassembly and installation of the stick end attachments. In one configuration, the dual solenoid valve A11 acts as the pilot solenoid valve for the excavator's main valve, and the main valve is equipped with a locking oil for the quick-connect coupling. The double solenoid valve A11 serves as the pilot solenoid valve for both the locking and unlocking ports on the main valve. When the unlocking command is executed, the unlocking port portion of the double solenoid valve A11 pushes the valve core of the unlocking port on the main valve, allowing hydraulic oil to enter the double-acting hydraulic cylinder of the quick-change connector. The quick-change connector then unlocks and lowers the attachment. When the locking command is executed, the locking port portion of the double solenoid valve A11 pushes the valve core of the locking port on the main valve, allowing hydraulic oil to enter the double-acting hydraulic cylinder of the quick-change connector. The quick-change connector then locks the attachment.
[0043] Specifically, the right handle module 19 generates a proportional voltage signal by shifting left or right and transmits it to the auxiliary data processing module 8. After data processing, the auxiliary data processing module 8 sends a proportional current signal to the double solenoid valve B12 to realize the action of the attachment. The left handle module 18 generates a proportional voltage signal by shifting left or right and transmits it to the auxiliary data processing module 8. After data processing, the auxiliary data processing module 8 sends a proportional current signal to the double solenoid valve D14 to realize the action of the attachment. The excavator's main valve is equipped with an oil port for attachment action. The double solenoid valves B12 and D14 serve as pilot solenoid valves on the main valve. The main valve oil port is connected to the hydraulic drive components on the attachment. When an action command is executed, the double solenoid valves B12 and D14 push the corresponding main valve core to realize the action of the attachment, such as the release and gripping, lowering and rotating of the gripper.
[0044] Specifically, the double solenoid valve C13 is a proportional current spring-type solenoid valve. In the attachment pressure adjustment interface of the data display module 3, the percentage of oil pressure is adjusted. The data display module 3 transmits a signal to the auxiliary data processing module 8, and the auxiliary data processing module 8 outputs a proportional current signal to the double solenoid valve C13. The double solenoid valve C13 adjusts the pressure of the attachment actuation oil circuit, thereby regulating the pressure of the attachment oil circuit. The double solenoid valve C13 is installed in the attachment actuation oil circuit. By setting the percentage of oil pressure in the attachment pressure adjustment interface, it achieves the overflow function after reaching the target pressure. The double solenoid valve C13 acts as the pressure safety center of the attachment actuation oil circuit. By adjusting the overflow pressure threshold, it ensures the stability of the attachment oil circuit under different working conditions.
[0045] Specifically, the double solenoid valve E15 is a bidirectional voltage-type solenoid valve for switching. The operator switches to the attachment mode via the data display module 3. The data display module 3 transmits data to the auxiliary data processing module 8, which then sends a command to the double solenoid valve E15. The double solenoid valve E15 then switches to bidirectional mode, enabling the excavator's attachment mode. The operator again switches to the attachment mode via the data display module 3, which transmits data to the auxiliary data processing module 8. The auxiliary data processing module 8 then sends a command to the double solenoid valve E15. The double solenoid valve E15 is located within the double solenoid valve B12. The control oil circuit of the double solenoid valve D14 and the two circuits of the double solenoid valve E15 are both connected. The double solenoid valves B12 and D14 are working normally to realize the attachment mode and meet the various actions of the attachment. The operator sends the data display module 3 to the breaker mode. The data display module 3 transmits data to the auxiliary data processing module 8. The auxiliary data processing module 8 sends a command to the double solenoid valve E15. Only one circuit of the double solenoid valve E15 is connected. One of the double solenoid valves B12 and D14 is connected to the oil pump to realize the breaker mode of the excavator and meet the single impact action requirement of the breaker.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
