There are large differences in the operating parameters of different brands of breakers, such as target flow and pressure setting, which brings certain technical challenges to the work of operators. At present, when the excavator is performing crushing operations, the main method is to manually adjust the parameters of the excavator's hydraulic system to adapt the rated parameters of the excavator and the breaker hammer, thereby ensuring the normal operation of the crushing operation.

[0028] In the modern engineering field, hydraulic excavators are widely used in industries such as mining and construction. In the crushing operation of the excavator, the breaker hammer is one of the key components, and its performance directly affects the construction efficiency and safety. There are large differences in the operating parameters of different brands of breakers, such as target flow and pressure setting, which brings certain technical challenges to the work of operators. At present, when the excavator is performing crushing operations, the main method is to manually adjust the parameters of the excavator's hydraulic system to adapt the rated parameters of the excavator and the breaker hammer, thereby ensuring the normal operation of the crushing operation.

[0029] However, practice has shown that traditional breaker commissioning methods require frequent manual adjustments to the hydraulic system coefficients, resulting in complex and time-consuming operations and a reduction in overall crushing efficiency. Furthermore, frequent commissioning can easily lead to improper parameter settings due to human error, resulting in equipment damage and potentially causing operational safety accidents.

[0030] Therefore, how to improve the efficiency and safety of excavator crushing operations is a technical problem that needs to be solved urgently.

[0031] To solve the above technical problems, the present invention discloses a method and device for controlling crushing operations of an excavator, aiming to improve the efficiency and safety of the excavator's crushing operations. Detailed descriptions are provided below.

[0032] Example 1 See also Figure 1 , Figure 1 The present invention is a flowchart of a method for controlling a crushing operation of an excavator disclosed in an embodiment of the present invention. Figure 1The method shown can be applied to a crushing operation control device, which can improve the efficiency and safety of the excavator's crushing operation. Furthermore, the device can be integrated into the excavator's main control system or can exist independently of the excavator's main control system, which is not limited in the embodiment of the present invention. Figure 1 As shown, the embodiment of the present invention discloses a crushing operation control method for an excavator, including but not limited to the following operations: 101. Obtain a breaker hammer selection instruction, and perform parameter matching in a preset breaker hammer database based on the breaker hammer selection instruction to obtain target breaker hammer parameters; the breaker hammer selection instruction is generated based on a breaker hammer selection operation performed by human-computer interaction at a previous moment; 102. Determine the target driving flow rate according to the target breaker parameters; 103. The pump output flow of the excavator's crushing drive pump is controlled according to the target drive flow to control the excavator to perform crushing operations; the crushing drive pump is used to drive the excavator's crushing hammer to work.

[0033] It should be noted that the breaker database includes pre-tuned and optimized matching data for several breaker brands and models. Excavator operators can switch to the corresponding breaker brand and model by simply selecting it through the excavator instrument panel.

[0034] In an embodiment of the present invention, a breaker hammer selection instruction is first obtained, and parameters are matched in a preset breaker hammer database according to the breaker hammer selection instruction to obtain target breaker hammer parameters; then, a target drive flow rate is determined according to the target breaker hammer parameters, and then the pump output flow rate of the excavator's breaker drive pump is controlled according to the target drive flow rate to control the excavator to perform a crushing operation.

[0035] It can be seen that the embodiment of the present invention realizes the breaker hammer selection switching and matches the corresponding breaker hammer parameters through the pre-built breaker hammer database, simplifies the operation process, eliminates the need for manual repeated debugging, improves the convenience of operation, reduces the error rate of operation, and thus improves the efficiency and safety of the excavator's crushing operation.

[0036] In an optional embodiment, obtaining a breaker hammer selection instruction and performing parameter matching in a preset breaker hammer database according to the breaker hammer selection instruction to obtain target breaker hammer parameters include: Obtaining a breaker hammer selection instruction and parsing the breaker hammer selection instruction to obtain target breaker hammer information; the target breaker hammer information at least includes a target operating gear and a target breaker hammer model; Obtain the current working gear of the excavator, and perform gear adaptation judgment based on the current working gear and the target working gear to obtain the gear adaptation judgment result; If the gear adaptation judgment result indicates that the current working gear is adapted to the target working gear, then parameter matching is performed in a preset breaker hammer database according to the target breaker hammer model to obtain the target breaker hammer parameters; If the gear adaptation judgment result indicates that the current working gear is not compatible with the target working gear, a gear adjustment prompt is issued to the excavator driver. After receiving the gear confirmation command, the parameters of the target breaker model are matched in the preset breaker database to obtain the target breaker parameters. The gear confirmation instruction is generated based on the gear adjustment operation and adjustment confirmation operation of the human-computer interaction at the previous moment.

[0037] It can be understood that the gear adjustment prompt includes the target gear information recommended for adjustment. The gear adjustment operation is the operation of switching the excavator's working gear after the excavator driver receives the gear adjustment prompt. The adjustment confirmation operation is the operation of the excavator driver switching to the appropriate gear and interacting with the excavator to confirm that the adjustment is completed (such as clicking the "Adjustment Completed" button on the instrument).

[0038] In this optional embodiment, after the user selects the corresponding breaker hammer brand and model, if the gear currently used by the excavator does not match the embedded parameters, the instrument will remind the user and prompt him to use the corresponding gear.

[0039] It can be seen that this optional embodiment can help users avoid incorrect operations during crushing operations and improve operation safety.

[0040] In another optional embodiment, determining the target driving flow rate according to the target breaker hammer parameter includes: Calculate the initial driving flow rate according to the target breaker parameters; Obtaining a mode selection instruction and determining a target flow control mode according to the mode selection instruction; the mode selection instruction is generated according to a flow control mode selection operation of a previous human-computer interaction; The target driving flow rate is determined according to the target flow rate control mode and the initial driving flow rate.

[0041] This optional embodiment determines the corresponding target driving flow rate in combination with the flow control mode after obtaining the target breaker parameters.

[0042] In yet another optional embodiment, determining the target driving flow rate according to the target flow rate control mode and the initial driving flow rate includes: If the target flow control mode is the automatic control mode, the initial driving flow is determined to be the target driving flow; If the target flow control mode is the manual control mode, the flow adjustment parameter is obtained, and the initial driving flow is updated according to the flow adjustment parameter to obtain the target driving flow; The flow adjustment parameters are generated based on the flow adjustment operation of human-computer interaction at a previous moment.

[0043] It can be seen that this optional embodiment can adjust the flow rate up and down based on the initial driving flow rate through the manual control mode, meeting the driver's need to manually adjust the flow rate and enhancing the adaptability of the excavator to crushing operations under different working conditions.

[0044] In another optional embodiment, the target drive flow rate is dynamically compensated by obtaining ambient temperature parameters and altitude parameters. The specific process is as follows: the ambient temperature parameters are collected in real time through the excavator's built-in temperature sensor, and the altitude parameters of the current working area are obtained through a barometer; a dynamic compensation database containing a temperature-flow compensation coefficient comparison table and an altitude-flow attenuation coefficient comparison table is established; the difference between the ambient temperature parameter and a preset reference temperature value (25°C) is calculated to obtain a temperature deviation value, and a first compensation coefficient is matched in the temperature-flow compensation coefficient comparison table based on the temperature deviation value; the altitude parameter is input into the altitude-flow attenuation coefficient comparison table to match a second compensation coefficient; an environmentally adaptive flow value is generated based on the first compensation coefficient and the second compensation coefficient, and the original target drive flow rate is updated to control the crushing drive pump.

[0045] It can be seen that this optional embodiment solves the problem of engine power attenuation caused by changes in hydraulic oil viscosity in cold / high temperature environments and thin air in plateau areas through dynamic compensation, avoids insufficient hammer output or overheating of the hydraulic system due to environmental factors, and improves operational stability under extreme working conditions.

[0046] In another alternative embodiment, the excavator of the present invention integrates an RFID reader / writer at the hydraulic quick-change joint, and embeds an RFID tag storing the model, rated pressure, and flow requirements at the breaker mounting base. When the breaker is connected to the excavator, the tag information is automatically read and verified to be in the breaker database: If it exists, directly call the pre-stored parameters to generate the target breaker parameters; If it does not exist, start the self-learning mode: when the breaker is in the no-load state, gradually increase the driving flow from the lowest flow rate with a preset step size (such as 10L / min), and record the system pressure corresponding to each flow rate through the pressure sensor; when the pressure mutation value exceeds the threshold (such as 5MPa), it is determined that the minimum starting force of the breaker is reached, and the flow value at this moment is recorded as the benchmark parameter; based on the benchmark parameter, the recommended working flow is calculated according to the preset ratio (such as 120%), and the user is prompted to confirm whether to save it to the database.

[0047] It can be seen that this optional embodiment solves the problem of rapid adaptation of new models / non-standard breaker hammers through intelligent recognition of breaker hammers and parameter self-learning, reduces the error rate of manual parameter entry, and expands the coverage of the database.

[0048] In yet another optional embodiment, controlling the pump output flow of a crushing drive pump of an excavator according to a target drive flow to control the excavator to perform a crushing operation includes: Obtaining the current engine speed of the excavator, and calculating the deviation between the current engine speed and the pre-stored historical engine speed to obtain the current speed deviation value; If the current speed deviation value is greater than a preset speed deviation threshold, the target drive flow rate is updated according to the current speed deviation value, and the pump output flow rate of the crushing drive pump is controlled according to the updated target drive flow rate to control the excavator to perform the crushing operation; If the current speed deviation value is less than or equal to the preset speed deviation threshold, the pump output flow of the crushing drive pump of the excavator is controlled according to the target drive flow to control the excavator to perform crushing operation.

[0049] It can be seen that the optional embodiment collects real-time engine speed and actively adjusts the pump output flow when the engine speed fluctuates, thereby achieving a constant flow output of the excavator and maintaining the stability of the crushing operation.

[0050] In another optional embodiment, a high-frequency vibration sensor is installed in the hydraulic circuit of the breaker hammer to collect the breaker hammer impact vibration signal in real time. The main vibration frequency component is extracted through fast Fourier transform (FFT), and the main vibration frequency is compared with a preset standard frequency range (e.g., 8-15 Hz): If the main vibration frequency is continuously higher than the upper limit of the range, it is judged as a "dry run" state, and the drive flow rate is automatically reduced by 5% steps until the frequency falls back to within the range; If the main vibration frequency is continuously lower than the lower limit of the interval, it is judged as an "overload" state, and the drive flow rate is automatically increased by 5% steps until the frequency reaches the standard; If the frequency fluctuates within the range, the current flow output is maintained.

[0051] In addition, the optimal frequency-flow mapping relationship of each crushed material is recorded during the crushing operation to form a material feature library for subsequent operations.

[0052] It can be seen that this optional embodiment optimizes flow output in real time through vibration feedback, solves the problem of different impact energy required for materials of different hardness (concrete / granite, etc.), prevents equipment damage caused by empty hitting and efficiency loss caused by overload, and improves crushing adaptability.

[0053] In yet another optional embodiment, a crushing operation control method for an excavator disclosed in an embodiment of the present invention further includes: Obtaining the operating time information of the current driving pump of the excavator; the current driving pump is the crushing driving pump that drives the breaker hammer of the excavator at the current moment; Perform pump switching judgment based on the operation duration information and the preset crushing duration threshold to obtain a pump switching judgment result; If the pump switching judgment result indicates that the crushing operation time of the current driving pump is greater than the crushing time threshold, the pump switching operation is performed on the excavator; If the pump switching judgment result indicates that the crushing operation duration of the current driving pump is less than or equal to the crushing duration threshold, the current driving pump is kept driving the breaker hammer of the excavator to operate.

[0054] During traditional excavator crushing operations, the breaker hammer drive pump is prone to overheating and wear due to long-term and high-intensity hammering operations, affecting the service life and reliability of the drive pump.

[0055] It can be seen that this optional embodiment does not require the user to manually adjust the breaker hammer drive pump, and automatically switches the breaker hammer drive pump according to the current operating time of the drive pump and the preset crushing time threshold, thereby extending the service life of the drive pump and reducing maintenance costs.

[0056] In yet another optional embodiment, performing a pump switching operation on an excavator includes: Get the current engine status of the excavator; If the current engine state is running, the current driving pump drives the excavator's breaker hammer to work; If the current engine state is the off state, the current operation date of the excavator is obtained, and the current operation date is judged to be odd or even to obtain the odd or even number judgment result; If the odd-even number determination result indicates that the current operation date is an odd-numbered date, the first driving pump is controlled to drive the breaker hammer of the excavator to operate; If the odd-even number judgment result indicates that the current operation date is an even-numbered date, the second driving pump is controlled to drive the breaker hammer of the excavator to work; The first driving pump and the second driving pump are both driving pumps other than the current driving pump configured for the excavator.

[0057] This optional embodiment automatically switches between different drive pumps for hammering based on odd and even days, reducing the impact of long-term single-pump operation on pump life, extending the equipment's lifespan and reducing maintenance costs. Furthermore, this automatic switching mechanism ensures balanced use of multiple pumps, ensuring the equipment remains in optimal condition over extended periods of operation.

[0058] In another optional embodiment, an independent working time accumulation unit is created in the memory for each drive pump; when a pump switching operation is performed, the drive pump with the shortest cumulative working time is preferentially selected as the switching target; if there are multiple candidate pumps with the same working time, the drive pump with the highest ranking is selected according to a preset pump performance priority list (arranged in descending order by factory-calibrated flow accuracy); after each pump switching is completed, the cumulative working time data of the enabled drive pump is updated. At the same time, a pump health monitoring module is set up: during the operation of the drive pump, the frequency of its outlet oil pressure fluctuation is collected in real time. If the number of pressure fluctuations per unit time exceeds a preset threshold (such as 10 times / second), the pump is determined to have abnormal pulsation, and it is automatically and temporarily isolated from the candidate pump list and a maintenance alarm is triggered.

[0059] It can be seen that this optional embodiment avoids overload losses of a single pump and extends the overall life of the multi-pump system through a dual decision-making mechanism of accumulated working hours and performance priority; oil pressure fluctuation monitoring can detect internal wear faults of the pump in advance and prevent operation interruptions caused by sudden failures.

[0060] In another optional embodiment, multiple sets of infrared ranging sensors are installed on the excavator working device to monitor the distance between the breaker and key components such as the cab and engine compartment in real time; three levels of safety thresholds are set: When the distance to the cab is less than 1.5 meters, the first level alarm is triggered and the pump output flow is reduced to 50%; When the distance is less than 1 meter, the secondary alarm is triggered and the hydraulic supply is cut off, forcing the crushing action to stop; If the breaker's swing trajectory is detected to overlap with the engine compartment's projection area, the slewing mechanism is immediately locked. A posture safety model is also established: the boom / arm angle is acquired through an inclination sensor. If the calculated angle between the breaker's theoretical trajectory and the machine body is less than 15°, a collision risk is determined and the operation is automatically terminated.

[0061] This optional embodiment eliminates equipment collision accidents caused by blind spots in the operating field of view through dual monitoring of spatial distance and posture. It is particularly suitable for operations in narrow spaces and ensures the safety of humans and machines.

Figure 2 The device shown can be used to execute the crushing operation control method described in the first embodiment. The device can improve the efficiency and safety of the excavator's crushing operation. Furthermore, the device can be integrated into the main control system of the excavator or can exist independently of the main control system of the excavator. The embodiment of the present invention does not limit this. Figure 2As shown, the embodiment of the present invention discloses a crushing operation control device for an excavator, including but not limited to: The parameter matching module 201 is used to obtain a breaker hammer selection instruction and perform parameter matching in a preset breaker hammer database according to the breaker hammer selection instruction to obtain target breaker hammer parameters; the breaker hammer selection instruction is generated based on the breaker hammer selection operation of the previous human-computer interaction; A flow determination module 202 is configured to determine a target driving flow according to target breaker parameters; The operation control module 203 is used to control the pump output flow of the crushing drive pump of the excavator according to the target drive flow, so as to control the excavator to perform crushing operations; the crushing drive pump is used to drive the crushing hammer of the excavator to work.

[0063] It should be noted that the breaker database includes pre-tuned and optimized matching data for several breaker brands and models. Excavator operators can switch to the corresponding breaker brand and model by simply selecting it through the excavator instrument panel.

[0064] In an embodiment of the present invention, a breaker hammer selection instruction is first obtained, and parameters are matched in a preset breaker hammer database according to the breaker hammer selection instruction to obtain target breaker hammer parameters; then, a target drive flow rate is determined according to the target breaker hammer parameters, and then the pump output flow rate of the excavator's breaker drive pump is controlled according to the target drive flow rate to control the excavator to perform a crushing operation.

[0065] It can be seen that the embodiment of the present invention realizes the breaker hammer selection switching and matches the corresponding breaker hammer parameters through the pre-built breaker hammer database, simplifies the operation process, eliminates the need for manual repeated debugging, improves the convenience of operation, reduces the error rate of operation, and thus improves the efficiency and safety of the excavator's crushing operation.

[0066] In an optional embodiment, the parameter matching module 201 obtains the breaker hammer selection instruction and performs parameter matching in a preset breaker hammer database according to the breaker hammer selection instruction. The specific method of obtaining the target breaker hammer parameters includes: Obtaining a breaker hammer selection instruction and parsing the breaker hammer selection instruction to obtain target breaker hammer information; the target breaker hammer information at least includes a target operating gear and a target breaker hammer model; Obtain the current working gear of the excavator, and perform gear adaptation judgment based on the current working gear and the target working gear to obtain the gear adaptation judgment result; If the gear adaptation judgment result indicates that the current working gear is adapted to the target working gear, then parameter matching is performed in a preset breaker hammer database according to the target breaker hammer model to obtain the target breaker hammer parameters; If the gear adaptation judgment result indicates that the current working gear is not compatible with the target working gear, a gear adjustment prompt is issued to the excavator driver. After receiving the gear confirmation command, the parameters of the target breaker model are matched in the preset breaker database to obtain the target breaker parameters. The gear confirmation instruction is generated based on the gear adjustment operation and adjustment confirmation operation of the human-computer interaction at the previous moment.

[0067] It can be understood that the gear adjustment prompt includes the target gear information recommended for adjustment. The gear adjustment operation is the operation of switching the excavator's working gear after the excavator driver receives the gear adjustment prompt. The adjustment confirmation operation is the operation of the excavator driver switching to the appropriate gear and interacting with the excavator to confirm that the adjustment is completed (such as clicking the "Adjustment Completed" button on the instrument).

[0068] In this optional embodiment, after the user selects the corresponding breaker hammer brand and model, if the gear currently used by the excavator does not match the embedded parameters, the instrument will remind the user and prompt him to use the corresponding gear.

[0069] It can be seen that this optional embodiment can help users avoid incorrect operations during crushing operations and improve operation safety.

[0070] In another optional embodiment, the flow determination module 202 determines the target driving flow according to the target breaker parameters in the following manner: Calculate the initial driving flow rate according to the target breaker parameters; Obtaining a mode selection instruction and determining a target flow control mode according to the mode selection instruction; the mode selection instruction is generated according to a flow control mode selection operation of a previous human-computer interaction; The target driving flow rate is determined according to the target flow rate control mode and the initial driving flow rate.

[0071] This optional embodiment determines the corresponding target driving flow rate in combination with the flow control mode after obtaining the target breaker parameters.

[0072] In another optional embodiment, the flow determination module 202 determines the target driving flow according to the target flow control mode and the initial driving flow in a specific manner including: If the target flow control mode is the automatic control mode, the initial driving flow is determined to be the target driving flow; If the target flow control mode is the manual control mode, the flow adjustment parameter is obtained, and the initial driving flow is updated according to the flow adjustment parameter to obtain the target driving flow; The flow adjustment parameters are generated based on the flow adjustment operation of human-computer interaction at a previous moment.

[0073] It can be seen that this optional embodiment can adjust the flow rate up and down based on the initial driving flow rate through the manual control mode, meeting the driver's need to manually adjust the flow rate and enhancing the adaptability of the excavator to crushing operations under different working conditions.

[0074] In another optional embodiment, the target drive flow rate is dynamically compensated by obtaining ambient temperature parameters and altitude parameters. The specific process is as follows: the ambient temperature parameters are collected in real time through the excavator's built-in temperature sensor, and the altitude parameters of the current working area are obtained through a barometer; a dynamic compensation database containing a temperature-flow compensation coefficient comparison table and an altitude-flow attenuation coefficient comparison table is established; the difference between the ambient temperature parameter and a preset reference temperature value (25°C) is calculated to obtain a temperature deviation value, and a first compensation coefficient is matched in the temperature-flow compensation coefficient comparison table based on the temperature deviation value; the altitude parameter is input into the altitude-flow attenuation coefficient comparison table to match a second compensation coefficient; an environmentally adaptive flow value is generated based on the first compensation coefficient and the second compensation coefficient, and the original target drive flow rate is updated to control the crushing drive pump.

[0075] It can be seen that this optional embodiment solves the problem of engine power attenuation caused by changes in hydraulic oil viscosity in cold / high temperature environments and thin air in plateau areas through dynamic compensation, avoids insufficient hammer output or overheating of the hydraulic system due to environmental factors, and improves operational stability under extreme working conditions.

[0076] In another alternative embodiment, the excavator of the present invention integrates an RFID reader / writer at the hydraulic quick-change joint, and embeds an RFID tag storing the model, rated pressure, and flow requirements at the breaker mounting base. When the breaker is connected to the excavator, the tag information is automatically read and verified to be in the breaker database: If it exists, directly call the pre-stored parameters to generate the target breaker parameters; If it does not exist, start the self-learning mode: when the breaker is in the no-load state, gradually increase the driving flow from the lowest flow rate with a preset step size (such as 10L / min), and record the system pressure corresponding to each flow rate through the pressure sensor; when the pressure mutation value exceeds the threshold (such as 5MPa), it is determined that the minimum starting force of the breaker is reached, and the flow value at this moment is recorded as the benchmark parameter; based on the benchmark parameter, the recommended working flow is calculated according to the preset ratio (such as 120%), and the user is prompted to confirm whether to save it to the database.

[0077] It can be seen that this optional embodiment solves the problem of rapid adaptation of new models / non-standard breaker hammers through intelligent recognition of breaker hammers and parameter self-learning, reduces the error rate of manual parameter entry, and expands the coverage of the database.

[0078] In another optional embodiment, the operation control module 203 controls the pump output flow of the crushing drive pump of the excavator according to the target drive flow to control the excavator to perform the crushing operation. The specific method includes: Obtaining the current engine speed of the excavator, and calculating the deviation between the current engine speed and the pre-stored historical engine speed to obtain the current speed deviation value; If the current speed deviation value is greater than a preset speed deviation threshold, the target drive flow rate is updated according to the current speed deviation value, and the pump output flow rate of the crushing drive pump is controlled according to the updated target drive flow rate to control the excavator to perform the crushing operation; If the current speed deviation value is less than or equal to the preset speed deviation threshold, the pump output flow of the crushing drive pump of the excavator is controlled according to the target drive flow to control the excavator to perform crushing operation.

[0079] It can be seen that the optional embodiment collects real-time engine speed and actively adjusts the pump output flow when the engine speed fluctuates, thereby achieving a constant flow output of the excavator and maintaining the stability of the crushing operation.

[0080] In another optional embodiment, a high-frequency vibration sensor is installed in the hydraulic circuit of the breaker hammer to collect the breaker hammer impact vibration signal in real time. The main vibration frequency component is extracted through fast Fourier transform (FFT), and the main vibration frequency is compared with a preset standard frequency range (e.g., 8-15 Hz): If the main vibration frequency is continuously higher than the upper limit of the range, it is judged as a "dry run" state, and the drive flow rate is automatically reduced by 5% steps until the frequency falls back to within the range; If the main vibration frequency is continuously lower than the lower limit of the interval, it is judged as an "overload" state, and the drive flow rate is automatically increased by 5% steps until the frequency reaches the standard; If the frequency fluctuates within the range, the current flow output is maintained.

[0081] In addition, the optimal frequency-flow mapping relationship of each crushed material is recorded during the crushing operation to form a material feature library for subsequent operations.

[0082] It can be seen that this optional embodiment optimizes flow output in real time through vibration feedback, solves the problem of different impact energy required for materials of different hardness (concrete / granite, etc.), prevents equipment damage caused by empty hitting and efficiency loss caused by overload, and improves crushing adaptability.

[0083] See also Figure 3 , Figure 3 This is a schematic diagram of another structure of a crushing operation control device for an excavator disclosed in an embodiment of the present invention. Figure 3 As shown, the crushing operation control device for an excavator disclosed in an embodiment of the present invention further includes: The duration acquisition module 204 is used to acquire the operation duration information of the current driving pump of the excavator; the current driving pump is the crushing driving pump that drives the crushing hammer of the excavator at the current moment; The pump switching judgment module 205 is used to perform pump switching judgment based on the operation duration information and the preset crushing duration threshold, and obtain a pump switching judgment result; A pump switching execution module 206 is configured to execute a pump switching operation on the excavator if the pump switching judgment result indicates that the crushing operation duration of the current driving pump is greater than the crushing duration threshold; The driving pump maintaining module 207 is configured to maintain the current driving pump driving the excavator's breaker hammer in operation if the pump switching judgment result indicates that the crushing operation duration of the current driving pump is less than or equal to the crushing duration threshold.

[0084] During traditional excavator crushing operations, the breaker hammer drive pump is prone to overheating and wear due to long-term and high-intensity hammering operations, affecting the service life and reliability of the drive pump.

[0085] It can be seen that this optional embodiment does not require the user to manually adjust the breaker hammer drive pump, and automatically switches the breaker hammer drive pump according to the current operating time of the drive pump and the preset crushing time threshold, thereby extending the service life of the drive pump and reducing maintenance costs.

[0086] In another optional embodiment, the specific manner in which the pump switching execution module 206 performs the pump switching operation on the excavator includes: Get the current engine status of the excavator; If the current engine state is running, the current driving pump drives the excavator's breaker hammer to work; If the current engine state is the off state, the current operation date of the excavator is obtained, and the current operation date is judged to be odd or even to obtain the odd or even number judgment result; If the odd-even number determination result indicates that the current operation date is an odd-numbered date, the first driving pump is controlled to drive the breaker hammer of the excavator to operate; If the odd-even number judgment result indicates that the current operation date is an even-numbered date, the second driving pump is controlled to drive the breaker hammer of the excavator to work; The first driving pump and the second driving pump are both driving pumps other than the current driving pump configured for the excavator.

[0087] This optional embodiment automatically switches between different drive pumps for hammering based on odd and even days, reducing the impact of long-term single-pump operation on pump life, extending the equipment's lifespan and reducing maintenance costs. Furthermore, this automatic switching mechanism ensures balanced use of multiple pumps, ensuring the equipment remains in optimal condition over extended periods of operation.

[0088] In another optional embodiment, an independent working time accumulation unit is created in the memory for each drive pump; when a pump switching operation is performed, the drive pump with the shortest cumulative working time is preferentially selected as the switching target; if there are multiple candidate pumps with the same working time, the drive pump with the highest ranking is selected according to a preset pump performance priority list (arranged in descending order by factory-calibrated flow accuracy); after each pump switching is completed, the cumulative working time data of the enabled drive pump is updated. At the same time, a pump health monitoring module is set up: during the operation of the drive pump, the frequency of its outlet oil pressure fluctuation is collected in real time. If the number of pressure fluctuations per unit time exceeds a preset threshold (such as 10 times / second), the pump is determined to have abnormal pulsation, and it is automatically and temporarily isolated from the candidate pump list and a maintenance alarm is triggered.

[0089] It can be seen that this optional embodiment avoids overload losses of a single pump and extends the overall life of the multi-pump system through a dual decision-making mechanism of accumulated working hours and performance priority; oil pressure fluctuation monitoring can detect internal wear faults of the pump in advance and prevent operation interruptions caused by sudden failures.

[0090] In another optional embodiment, multiple sets of infrared ranging sensors are installed on the excavator working device to monitor the distance between the breaker and key components such as the cab and engine compartment in real time; three levels of safety thresholds are set: When the distance to the cab is less than 1.5 meters, the first level alarm is triggered and the pump output flow is reduced to 50%; When the distance is less than 1 meter, the secondary alarm is triggered and the hydraulic supply is cut off, forcing the crushing action to stop; If the breaker's swing trajectory is detected to overlap with the engine compartment's projection area, the slewing mechanism is immediately locked. A posture safety model is also established: the boom / arm angle is acquired through an inclination sensor. If the calculated angle between the breaker's theoretical trajectory and the machine body is less than 15°, a collision risk is determined and the operation is automatically terminated.

[0091] This optional embodiment eliminates equipment collision accidents caused by blind spots in the operating field of view through dual monitoring of spatial distance and posture. It is particularly suitable for operations in narrow spaces and ensures the safety of humans and machines.
