Description

Technical Field

[0001] This invention relates to an automatic cleaning method and system for dust filters on excavator radiators, belonging to the technical field of excavator radiator technology. Background Technology

[0002] Currently, radiators frequently experience overheating alarms due to clogged dust filters caused by drivers forgetting to clean them, affecting their normal operation. Furthermore, the dust filters currently rely primarily on manual cleaning; they lack an automatic cleaning function. Drivers need to frequently check for clogs, and if clogged and left unattended, they will negatively impact radiator performance, leading to overheating. Manual cleaning requires removing the dust filter, which is time-consuming. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic cleaning method and system for excavator radiator dust screens. This system can automatically detect the dust screen blockage and then automatically clean the radiator dust screen according to the driver's needs, preventing the driver from forgetting to clean the dust screen and causing radiator blockage. It can also automatically clean the dust screen, saving time.

[0004] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0005] In a first aspect, the present invention provides an automatic cleaning method for the dust filter of an excavator radiator, comprising:

[0006] Acquire pressure data collected by pressure sensors installed on the air inlet and air outlet sides of the dustproof screen;

[0007] Calculate the real-time pressure difference between the two sides of the dustproof net based on the pressure data;

[0008] The real-time pressure difference is compared with multiple preset clogging level thresholds to determine the current clogging level of the dustproof net;

[0009] Based on the current congestion level, generate and issue a corresponding alarm control signal to trigger a visual and audible alarm that matches the current congestion level;

[0010] In response to the received user operation command and in combination with the current blockage level, a corresponding motor control signal is generated and sent to control the vibration motor to perform the corresponding cleaning action;

[0011] During the cleaning process, the pressure data is continuously acquired and the real-time pressure difference is calculated. When the real-time pressure difference reaches the preset cleaning completion threshold, a stop signal is sent to the vibration motor.

[0012] Furthermore, the preset multiple congestion level thresholds include a mild congestion threshold Pa, a moderate congestion threshold Pb, and a severe congestion threshold Pc, where Pa < Pb < Pc;

[0013] Determining the current clogging level of the dust control net includes:

[0014] If the real-time pressure difference ΔP > Pa, it is determined to be a mild blockage level;

[0015] If the real-time pressure difference ΔP > Pb, it is determined to be a moderate blockage level;

[0016] If the real-time pressure difference ΔP > Pc, it is determined to be a severe blockage level.

[0017] Furthermore, the step of generating and issuing a corresponding alarm control signal based on the current congestion level includes:

[0018] If the blockage level is mild, the corresponding alarm control signal will be sent to make the alarm switch turn green and start the audible alarm.

[0019] If the blockage level is moderate, the corresponding alarm control signal will be sent to make the alarm switch light turn yellow and start the audible alarm.

[0020] If the blockage level is severe, a corresponding alarm control signal will be sent to make the alarm switch light turn red and activate the audible alarm.

[0021] Furthermore, the user operation instructions include cleanup instructions and cancel instructions;

[0022] The process of responding to a received user operation command and, in conjunction with the current congestion level, generating and issuing a corresponding motor control signal includes:

[0023] When a cleaning command is received, regardless of the level of blockage, a start signal is sent to the vibration motor to begin cleaning.

[0024] When a cancellation command is received:

[0025] If the current level of congestion is mild, a signal is sent to the alarm switch to turn off the alarm and cancel the cleaning task;

[0026] If the current level of congestion is moderate, a signal will be sent to the alarm switch to turn off the alarm, but the yellow light will remain on, and the cleaning task will be canceled.

[0027] If the current level is severe congestion, a signal is sent to the alarm switch to turn off the alarm, but the red light remains on, and the cleanup task is set to delayed execution mode.

[0028] Furthermore, in the case of severe congestion and in delayed execution mode, the method also includes: continuously monitoring engine speed data, and when the speed data indicates that the engine is idling, automatically sending a start signal to the vibration motor to perform the cleaning action.

[0029] Furthermore, the preset cleaning completion threshold is the initial pressure difference P0 calculated when the system is first powered on; when the real-time pressure difference ΔP drops to ≤P0, the cleaning is determined to be complete.

[0030] Secondly, the present invention provides an automatic cleaning system for the dust filter of an excavator radiator, comprising:

[0031] The first pressure sensor P1 is located on the air inlet side of the radiator dust filter;

[0032] The second pressure sensor P2 is located on the air outlet side of the radiator dust filter;

[0033] The alarm switch is equipped with a visual indicator light and an audible alarm.

[0034] A vibration motor is installed on the dust filter of the radiator;

[0035] The overall controller is electrically connected to the first pressure sensor P1, the second pressure sensor P2, the alarm switch, and the vibration motor, respectively.

[0036] The machine controller is configured to perform the steps of the automatic cleaning method for the excavator radiator dust screen described in any of the preceding claims.

[0037] Thirdly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods described above.

[0038] Fourthly, the present invention provides an electronic device, comprising:

[0039] Memory, used to store computer programs / instructions;

[0040] A processor for executing the computer program / instructions to implement the steps of any of the methods described above.

[0041] Fifthly, the present invention provides a computer program product, including a computer program / instructions that, when executed by a processor, implement the steps of any of the methods described above.

[0042] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0043] This invention provides an automatic cleaning method and system for excavator radiator dust screens. It can automatically detect the dust screen blockage and then automatically clean the radiator dust screen according to the driver's needs, avoiding the driver forgetting to clean the dust screen and causing radiator blockage.

[0045] Figure 2 This is a flowchart of an automatic cleaning method for the dust filter of an excavator radiator provided in an embodiment of the present invention. Detailed Implementation

[0046] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0047] Example 1: This example describes an automatic cleaning method for the dust filter of an excavator radiator, including:

[0048] Acquire pressure data collected by pressure sensors installed on the air inlet and air outlet sides of the dustproof screen;

[0049] Calculate the real-time pressure difference between the two sides of the dustproof net based on the pressure data;

[0050] The real-time pressure difference is compared with multiple preset clogging level thresholds to determine the current clogging level of the dustproof net;

[0051] Based on the current congestion level, generate and issue a corresponding alarm control signal to trigger a visual and audible alarm that matches the current congestion level;

[0052] In response to the received user operation command and in combination with the current blockage level, a corresponding motor control signal is generated and sent to control the vibration motor to perform the corresponding cleaning action;

[0053] During the cleaning process, the pressure data is continuously acquired and the real-time pressure difference is calculated. When the real-time pressure difference reaches the preset cleaning completion threshold, a stop signal is sent to the vibration motor.

[0054] like Figure 2 As shown in the figure, the automatic cleaning method for excavator radiator dust screens provided in this embodiment involves the following steps in its application process:

[0055] Step 1: When the excavator's controller is powered on for the first time, the first pressure sensor P1 on the air inlet side and the second pressure sensor P2 on the air outlet side of the radiator dust filter start working. The controller collects the signals from P1 and P2 at this time, calculates the initial pressure difference P0 of the dust filter in the clean state, and stores this value in the controller's memory as a benchmark threshold for subsequent judgment of whether cleaning is complete.

[0056] Step 2: During the excavator's operation, the controller continuously receives real-time pressure signals from pressure sensors P1 and P2 and calculates the real-time pressure difference ΔP (ΔP = P2 - P1). The controller has three preset incremental blockage level thresholds: mild blockage threshold Pa, moderate blockage threshold Pb, and severe blockage threshold Pc, where Pa < Pb < Pc.

[0057] If ΔP > Pa, the controller determines that the dust filter is slightly clogged.

[0058] If ΔP > Pb, the controller determines it to be a moderate blockage.

[0059] If ΔP > Pc, the controller determines it to be a severe blockage.

[0060] Step 3: Based on the determined blockage level, the controller sends a corresponding first control signal to the alarm switch in the driver's cab, triggering an audible and visual alarm.

[0061] Mild blockage: The green indicator light on the alarm switch illuminates, and the buzzer emits an intermittent warning sound.

[0062] Moderate blockage: The yellow indicator light on the alarm switch illuminates, and the buzzer emits more frequent warning sounds.

[0063] Severe blockage: The red indicator light on the alarm switch illuminates, and the buzzer emits a continuous alarm sound.

[0064] Step 4: After observing the alarm, the driver can operate the clear / pause / cancel button on the alarm switch to issue a command. The controller receives the user's command and, based on the current congestion level, executes different strategies:

[0065] If the driver presses the clean button:

[0066] The controller immediately sends a start signal to the vibration motor installed on the dustproof net frame. The motor starts working, causing the dustproof net to vibrate and shake off the dust.

[0067] The controller continuously monitors the real-time pressure difference ΔP. When ΔP drops to ≤ the initial pressure difference P0, the cleaning is considered complete, and the controller sends a stop signal to the vibration motor, causing the motor to stop. Simultaneously, the controller sends a signal to the alarm switch to shut off all indicator lights and the audible alarm.

[0068] If the driver presses the pause / cancel button:

[0069] The current blockage is mild: The controller sends a signal to the alarm switch to turn off the green indicator light and the audible alarm, and cancels the current cleaning task.

[0070] The current blockage is moderate: The controller sends a signal to the alarm switch to turn off the sound alarm, but the yellow indicator light remains on, and the current cleaning task is canceled.

[0071] The current situation is severe congestion: the controller sends a signal to the alarm switch to mute the audible alarm, but the red indicator light remains constantly on. The cleanup task is not canceled at this time, but rather enters a delayed pending state.

[0072] Step 5: For heavily blocked tasks that are in a delayed, pending state, the controller initiates additional monitoring logic:

[0073] The controller continuously monitors the engine speed signal transmitted from the engine control unit.

[0074] When the controller detects that the engine speed has dropped to the idle range, it determines that this is a safe and appropriate time to clean.

[0075] The controller automatically sends a start signal to the vibration motor to perform the cleaning operation, which stops when ΔP ≤ P0. The red indicator light turns off after cleaning is complete.

[0076] This embodiment utilizes automated pressure monitoring, tiered alarms, and intelligent response mechanisms to enable drivers to clearly understand the dust filter blockage status and flexibly choose to clean it immediately or postpone the process. In cases of severe blockage, the system can autonomously select a safe idling time for cleaning, ensuring heat dissipation efficiency without requiring frequent manual intervention from the driver, significantly improving operational efficiency and equipment maintenance convenience. The entire process is data-driven and logically closed-loop, achieving intelligent management of dust filter cleaning.
