Description

Technical Field

[0001] This invention relates to the field of crane DPF (Device Filter for Power Use), and more particularly to a human-machine interactive method, system, and storage medium for active regeneration of crane DPF. Background Technology

[0002] The national standard G17691-2018, "Emission Limits and Test Methods for Compression-Ignition and Gas-Fueled Spark-Ignition Engines and Automobiles," clearly stipulates that particulate matter emissions from engines and vehicles must meet relevant requirements. China VI diesel engines use diesel particulate filters (DPFs) to capture particulate matter generated by the engine, ensuring compliance with regulations. When particulate matter accumulates in the DPF to a certain level, it can obstruct exhaust flow, affecting vehicle power and fuel consumption, necessitating cleaning—a process called DPF regeneration. Automatic DPF regeneration during vehicle operation, which raises exhaust temperature, is called DPF on-the-go regeneration. If on-the-go regeneration fails, the accumulated carbon in the DPF continues to increase, reaching a certain limit, requiring the user to perform additional regeneration and carbon removal while the vehicle is stationary.

[0003] For the diesel engine matched with the crane, the crane spends most of its time lifting in place, with low engine speed, low load, and low exhaust temperature. The DPF (Dielectric Power Filter) lacks passive regeneration capability, leading to a continuous increase in carbon buildup in the DPF. When the crane is stationary, the engine cannot perform on-the-go regeneration, requiring the user to perform operational regeneration. Operational regeneration typically lasts 30-60 minutes, during which no lifting work can be performed, disrupting user operations. Currently, operational regeneration is achieved by automatically increasing engine speed and closing the intake throttle valve. However, when users are performing precision lifting requiring high stability, suddenly increasing engine speed or closing the intake throttle valve can cause changes in lifting rate, potentially leading to lifting accidents.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] In one or more embodiments, determining whether the current state of the vehicle is suitable for job regeneration includes: detecting the operating state of the crane; if the crane is not in operation, it indicates that the vehicle is suitable for job regeneration; if the crane is in operation, it is detected again after a period of time until the crane is not in operation.

[0009] In one or more embodiments, achieving the regeneration efficiency standard includes: real-time detection of the vehicle's DPF carbon load, comparison with the carbon load before entering the regeneration operation mode, and calculation of the regeneration efficiency η. The calculation formula is: η = (carbon load before regeneration - carbon load after regeneration) / carbon load before regeneration. When η ≥ 90%, the regeneration efficiency standard is achieved.

[0010] In one or more embodiments, entering the parking regeneration mode includes: the instrument panel generating a third reminder interface, the third reminder interface being used to remind the user that the vehicle has entered the parking regeneration mode and to remind the user to press the parking regeneration button; if an instruction from the user to activate the parking regeneration mode is received, then parking regeneration is initiated; if no instruction to activate the parking regeneration mode is received, then the engine reduces power.

[0011] In one or more embodiments, the driving regeneration trigger value is the DPF carbon loading corresponding to the catalyst limit of 950°C when the DPF front temperature is controlled at 620°C for drop idle condition testing.

[0012] In one or more embodiments, the parking regeneration trigger value is the DPF carbon loading corresponding to the catalyst limit of 950°C when the DPF front temperature is controlled at 600°C for drop idle condition testing.

[0013] In one or more embodiments, the power limit trigger value is the DPF carbon loading corresponding to the catalyst limit of 950°C when the DPF inlet temperature is controlled at 580°C for drop idle condition testing.

[0014] Secondly, the present invention provides a human-machine interactive crane DPF active regeneration system, characterized in that it is used to execute the methods described above, the system comprising: a detection module for real-time detection of the DPF carbon load of the vehicle; an acquisition module for acquiring a driving regeneration trigger value, a parking regeneration trigger value, and a power limit trigger value; a judgment module for judging whether the DPF carbon load has reached the driving regeneration trigger value; if not, normal lifting is performed; if it has reached the trigger value, the system judges whether the DPF carbon load has reached the parking regeneration trigger value; if the DPF carbon load has not reached the parking regeneration trigger value, the system enters the operation regeneration mode; if it has reached the trigger value, the system judges whether the DPF carbon load has reached the power limit trigger value; if the DPF carbon load has not reached the power limit trigger value, the system enters the parking regeneration mode; if it has reached the trigger value, the engine power output is reduced; and a start module for entering the operation regeneration mode and the parking regeneration mode, and reducing the engine power output.

[0015] Thirdly, the present invention provides a computer-readable storage medium, characterized in that the computer-readable storage medium stores a computer program, which, when executed by a processor, implements the above-described human-computer interactive crane DPF active regeneration method.

[0016] Compared with the prior art, the human-machine interactive crane DPF active regeneration method, system, and storage medium according to the present invention have the following advantages:

[0017] (1) Before parking regeneration and operation regeneration are required when the carbon load reaches the preset value, the user interaction interface pops up on the upper instrument panel. The regeneration work is carried out after receiving the user's instructions, which can reduce the risk of hoisting accidents caused by sudden increase in engine speed or change in hoisting speed after closing the intake throttle valve.

[0018] (2) When the carbon load is low, the lifting status of the crane needs to be checked before the operation regeneration. If the crane is in the lifting state, the interactive interface will pop up after the lifting is completed to remind the user to complete the operation regeneration. If the carbon load increases further until it exceeds the parking regeneration trigger value, the interactive interface will pop up regardless of the lifting state to remind the user to complete the operation regeneration as soon as possible.

[0019] (3) Before the operation is regenerated, the required regeneration time is predicted by combining the current carbon load with historical data, and the user is reminded in the interactive interface, so as to make it easier to arrange the regeneration time according to the user's hoisting needs.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

Furthermore, this application can take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to disk storage, D-ROM, optical storage, etc.) containing computer-usable program code.

[0024] This application is described with reference to flowchart illustrations and / or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of this application. It will be understood that each block of the flowchart illustrations and / or block diagrams, and combinations of blocks in the flowchart illustrations and / or block diagrams, can be implemented by computer program instructions.

[0027] Invention Concept: Since the crane spends most of its time hoisting in place, with low engine speed, low load, and low exhaust temperature, and the DPF lacks passive regeneration capability, user-mandated parking regeneration is required. Parking regeneration typically lasts 30-60 minutes, during which no hoisting work can be performed, disrupting user operations. If operational regeneration is performed, changes in engine speed and the opening and closing of the intake throttle valve can easily cause variations in hoisting speed, potentially leading to hoisting accidents. Therefore, before operational or parking regeneration, the user's hoisting status should be determined through a human-machine interface, enabling proactive control of both traveling and parking regeneration, reducing safety accidents caused by existing regeneration methods.

[0028] A human-computer interactive method for active regeneration of DPF (Dynamic Power Filter) in cranes, such as... Figure 1 As shown, the process includes: real-time detection of the vehicle's DPF carbon load; acquisition of driving regeneration trigger values, parking regeneration trigger values, and power limitation trigger values; determination of whether the DPF carbon load has reached the driving regeneration trigger value; if not, normal lifting proceeds; if it has, determination of whether the DPF carbon load has reached the parking regeneration trigger value; if the DPF carbon load has not reached the parking regeneration trigger value, entry into operation regeneration mode; if it has, determination of whether the DPF carbon load has reached the power limitation trigger value; if the DPF carbon load has not reached the power limitation trigger value, entry into parking regeneration mode; if it has, engine power output is reduced.

[0029] Specifically, the driving regeneration trigger value, the parking regeneration trigger value, and the power limiting trigger value are preset values. The driving regeneration trigger value is preferably the DPF carbon load corresponding to the catalytic converter limit of 950°C when the DPF inlet temperature is controlled at 620°C for a drop-idle test. The parking regeneration trigger value is preferably the DPF carbon load corresponding to the catalytic converter limit of 950°C when the DPF inlet temperature is controlled at 600°C for a drop-idle test. The power limiting trigger value is preferably the DPF carbon load corresponding to the catalytic converter limit of 950°C when the DPF inlet temperature is controlled at 580°C for a drop-idle test.

[0030] As an optional implementation, entering the operation regeneration mode includes: determining whether the current state of the vehicle is suitable for operation regeneration; if suitable for operation regeneration, detecting the DPF carbon load, predicting the regeneration time based on the DPF carbon load, generating a first reminder interface on the instrument panel, the first reminder interface being used to ask the user whether to enter the operation regeneration mode and displaying the predicted regeneration time; if a negative command is received from the user, the vehicle performs normal lifting; if a positive command is received from the user, the engine performs operation regeneration, generating a second reminder interface on the instrument panel, the second reminder interface being used to ask the user whether to close the operation regeneration mode; if a stop command is received from the user, the engine exits operation regeneration; if no stop command is received from the user, operation regeneration continues; when the regeneration efficiency reaches the target, the operation regeneration mode is closed.

[0031] Specifically, the engine's regeneration mode includes: slowly increasing the engine idle speed to improve the catalytic converter inlet temperature and its heat preservation capacity; tightening the throttle valve to further improve the catalytic converter inlet temperature and its heat preservation capacity; reducing injection timing to enhance the catalytic converter inlet temperature; and releasing far-injection to increase the DPF inlet temperature, ultimately achieving a DPF inlet temperature of 600℃. A second reminder interface is generated on the instrument panel to ask the user whether to turn off the regeneration mode. After regeneration is completed, a pop-up window on the upper instrument panel displays "Restore original speed?", which the user can select based on the lifting operation. The lifting rate only changes after the user selects "Allow". The carbon load pre-regeneration time prediction includes: detecting the current carbon load, retrieving the carbon load and its corresponding regeneration time from historical data, and predicting the current regeneration time. After regeneration is completed, the carbon load before regeneration and the regeneration time are transferred into the historical data to enrich the sample and facilitate the next regeneration time prediction. The user can plan the lifting time based on the predicted regeneration time and the lifting plan.

[0032] As an optional implementation, determining whether the current state of the vehicle is suitable for operation regeneration includes: detecting the operating state of the crane; if the crane is not in operation, it indicates that the vehicle is suitable for operation regeneration; if the crane is in operation, it is detected again after a period of time until the crane is not in operation.

[0033] Specifically, the interval is preferably 10 minutes, but can be set to other values ​​based on the crane's operating time. Detecting the crane's operating status includes detecting engine speed, main cylinder pressure, exhaust temperature, etc., and determining whether the crane is in operation based on these values. Since suddenly entering operation regeneration mode while the crane is in operation can easily lead to lifting accidents, no user reminders are given during crane operation. Only after the lifting is completed and the engine detects the completion, a pop-up window reminds the user to perform operation regeneration. Alternatively, the crane's operating status can be detected, and an operation regeneration mode reminder interface can pop up regardless of whether it is in operation, but if it is in operation, an additional prompt can be added to the window.

[0034] As an optional implementation method, achieving the regeneration efficiency standard includes: real-time detection of the vehicle's DPF carbon load, comparison with the carbon load before entering the regeneration operation mode, and calculation of the regeneration efficiency η. The calculation formula is: η = (carbon load before regeneration - carbon load after regeneration) / carbon load before regeneration. When η ≥ 90%, the regeneration efficiency standard is achieved.

[0035] Specifically, the calculation of the regeneration efficiency can also be achieved by retrieving similar carbon loads before and after regeneration from historical data and comparing them with the DPF carbon load of the vehicle in real time.

[0036] As an optional implementation, entering the parking regeneration mode includes: the instrument panel generating a third reminder interface, the third reminder interface being used to remind the user that the vehicle has entered the parking regeneration mode and to remind the user to press the parking regeneration button; if the user's instruction to activate the parking regeneration mode is received, then parking regeneration is initiated; if the user's instruction to activate the parking regeneration mode is not received, then the engine power is reduced.

[0037] Specifically, the reminder interface generated by the instrument can be a text reminder such as "Please perform parking regeneration," or a combination of text and voice reminders. When the user follows the prompts and presses the parking regeneration button to perform the parking regeneration operation, the user can resume normal hoisting operations after the regeneration is completed. If the user ignores the text reminder and does not perform parking regeneration, the carbon load will accumulate and exceed the power limit trigger value after a period of time. The engine will reduce power output, affecting the user's normal hoisting operations, and further urging the user to perform parking regeneration as soon as possible.

[0038] As an optional implementation, the driving regeneration trigger value is the DPF carbon loading corresponding to the catalyst limit of 950°C when the DPF front temperature is controlled at 620°C for drop idle condition testing.

[0039] Specifically, the DPF inlet temperature is controlled at 620℃ to conduct a drop idle condition test. The DPF carbon load corresponding to the peak exhaust temperature wave in the DPF carrier reaching the catalyst limit of 950℃ is the driving regeneration trigger value. When the DPF carbon load exceeds the driving regeneration trigger value, there is a risk of overheating and burning out the catalyst under the extreme condition of drop idle at the highest target DPF inlet temperature during operation regeneration, which requires cleaning carbon deposits.

[0040] As an optional implementation, the parking regeneration trigger value is the DPF carbon loading corresponding to the peak exhaust temperature wave in the DPF carrier reaching the catalyst limit of 950°C when the DPF front temperature is controlled at 600°C for drop idling test.

[0041] Specifically, the DPF inlet temperature is controlled at 600℃ to conduct a drop idle condition test. The DPF carbon load corresponding to the peak value of the exhaust temperature wave in the DPF carrier reaching the catalyst limit of 950℃ is the parking regeneration trigger value. When the DPF carbon load exceeds the parking regeneration trigger value, there is a risk of overheating and burning out the catalyst when encountering extreme conditions such as drop idle during regeneration.

[0042] As an optional implementation, the power limit trigger value is the DPF carbon loading corresponding to the catalyst limit of 950°C when the DPF inlet temperature is controlled at 580°C for drop idling test.

[0043] Specifically, the DPF inlet temperature is controlled at 580℃ to conduct a drop idle condition test. When the peak temperature wave in the DPF carrier reaches the catalyst limit of 950℃, the corresponding DPF carbon loading is the power limit trigger value. When the DPF carbon loading exceeds the power limit trigger value, there is a greater risk of overheating and burning out the catalyst during operation and regeneration.

[0044] Example 2: Based on the same inventive concept as the human-machine interactive crane DPF active regeneration method in the foregoing examples, this example provides a human-machine interactive crane DPF active regeneration system. The system is used to execute the method described in Example 1, and includes:

[0045] The detection module is used to detect the DPF carbon load of the vehicle in real time.

[0046] The acquisition module is used to acquire driving regeneration trigger values, parking regeneration trigger values, and power limit trigger values;

[0047] The judgment module is used to determine whether the DPF carbon load has reached the driving regeneration trigger value. If it has not reached the value, normal lifting is performed. If it has reached the value, the module determines whether the DPF carbon load has reached the parking regeneration trigger value. If the DPF carbon load has not reached the parking regeneration trigger value, the module enters the operation regeneration mode. If the DPF carbon load has reached the value, the module determines whether the DPF carbon load has reached the power limit trigger value. If the DPF carbon load has not reached the power limit trigger value, the module enters the parking regeneration mode. If the DPF carbon load has reached the value, the engine power output is reduced.

[0048] The start-up module is used to enter the operation regeneration mode and the parking regeneration mode, as well as to reduce the engine output power.

[0049] As one specific implementation, the detection module includes: the DPF carbon load detection unit and the crane operating status detection unit. The DPF carbon load detection unit can detect the DPF carbon load of the vehicle in real time; the crane operating status detection unit can detect the current status of the engine, such as engine speed, master cylinder pressure, exhaust temperature, etc.

[0050] The judgment module includes: a DPF carbon load analysis unit and a crane operation status analysis unit; the DPF carbon load analysis unit can compare the DPF carbon load obtained by the detection module with the traveling regeneration trigger value, the parking regeneration trigger value, and the power limit trigger value to determine whether the DPF carbon load has reached the traveling regeneration trigger value. If it has not reached the traveling regeneration trigger value, normal lifting is performed; if it has reached the driving regeneration trigger value, it is determined whether the DPF carbon load has reached the parking regeneration trigger value; if the DPF carbon load has not reached the parking regeneration trigger value, the parking regeneration mode is entered; if it has reached the parking regeneration trigger value, it is determined whether the DPF carbon load has reached the power limit trigger value; if the DPF carbon load has not reached the power limit trigger value, the parking regeneration mode is entered; if it has reached the parking regeneration trigger value, the engine power output is reduced; the crane operation status analysis unit can analyze the engine speed, main cylinder pressure, exhaust temperature, etc., obtained by the crane operation status detection unit to determine whether the crane is in operation.

[0051] It also includes a recording module, which is used to record and upload the changes in carbon loading before and after regeneration, as well as the time consumed during regeneration, to the prediction module after each DPF regeneration to form historical data.

[0052] It also includes a prediction module, which can compare the DPF carbon loading obtained by the detection module with historical data and predict the DPF regeneration time;

[0053] It also includes an interaction module, which includes a display unit and a receiving unit. The display unit can generate a user reminder interface based on the analysis results of the analysis module and the prediction results of the prediction module. The receiving unit can receive the user's selection results on the display unit.

[0054] The startup module can obtain the selection result of the receiving unit. If it receives a negative command input by the user, the vehicle will lift normally. If it receives a positive command input by the user, the engine will enter the driving regeneration mode and generate a second reminder interface on the instrument panel. The second reminder interface is used to ask the user whether to turn off the operation regeneration mode. If it receives a stop command input by the user, the engine will exit the driving regeneration mode. If it does not receive a stop command input by the user, the driving regeneration mode will continue. When the regeneration efficiency reaches the target, the operation regeneration mode will be turned off.

[0055] Example 3:

[0056] Based on the same inventive concept as the human-computer interaction crane DPF active regeneration method in the foregoing embodiment, this embodiment provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the human-computer interaction crane DPF active regeneration method as described in Embodiment 1.

[0057] In summary, a human-machine interactive crane DPF active regeneration method, system, and storage medium are provided. (1) Before parking regeneration and operational regeneration are required when the carbon load reaches a preset value, a user interface pops up on the upper structure instrument. Regeneration is performed only after receiving user instructions, which can reduce the risk of lifting accidents caused by sudden increases in engine speed or changes in lifting speed after closing the intake throttle valve. (2) When the carbon load is low, the lifting status of the crane needs to be detected before operational regeneration. If the crane is in the lifting state, the interactive interface will pop up again after the lifting is completed to remind the user to complete the operational regeneration. If the carbon load increases further until it exceeds the parking regeneration trigger value, the interactive interface will pop up regardless of the lifting state to remind the user to complete the operational regeneration as soon as possible. (3) Before operational regeneration, the required regeneration time is predicted by combining the current carbon load with historical data, and the user is reminded in the interactive interface, so as to facilitate the arrangement of regeneration time according to the user's lifting needs.
