Description

Technical Field

[0001] The present invention relates to the field of engines, and in particular to an early warning control method, device, equipment and readable storage medium for engine regeneration. Background Art

[0002] Engines are widely used in various industries. As the operating time increases, the engine needs to be regenerated to restore its performance. The engine regeneration work includes park regeneration, which is the regeneration work performed when the entire equipment stops working (only the engine is started). In related technologies, the user does not perceive the parking regeneration request after the engine issues the parking regeneration request. Therefore, the user will continue to use the engine and ignore the parking regeneration request, resulting in a further decline in the engine status, which may not only reduce the engine's operating efficiency but also increase maintenance costs.

[0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Summary of the Invention

[0004] The purpose of the present invention is to provide an early warning control method, device, equipment and readable storage medium for engine regeneration. In the present invention, a preset key function of the equipment is first set. When the engine issues a parking regeneration request, if the parking regeneration waiting time reaches a first preset time, all functions of the engine except the preset key function are disabled, so that the user can perceive the change in the equipment status at the first time, and thus control the equipment to perform parking regeneration of the engine in time, which can avoid further decline of the engine status, thereby helping to improve the working efficiency of the engine and reduce maintenance costs.

[0005] To solve the above technical problems, the present invention provides an early warning control method for engine regeneration, comprising:

[0006] After the engine issues a parking regeneration request, determining whether the parking regeneration waiting time reaches a first preset time, wherein the parking regeneration waiting time refers to the waiting time from when the engine issues the parking regeneration request to when the parking regeneration is performed;

[0007] If the threshold is reached, all functions of the engine device except for preset key functions are disabled to allow the engine to be regenerated in a timely manner. The preset key functions are those required to end the operation and enter the parked regeneration environment.

[0008] If not, the engine is controlled to perform parking regeneration in response to a parking regeneration command.

[0009] On the other hand, the first preset time duration is less than the first level limit time of the engine;

[0010] The first-level limit time of the engine refers to the time threshold required for the parking regeneration waiting time to trigger the engine to execute the torque limit action.

[0011] On the other hand, after determining whether the parking regeneration waiting time reaches the first preset time, the engine regeneration early warning control method further includes:

[0012] If it is reached, the control prompter prompts the parking regeneration request.

[0013] On the other hand, the prompter includes a local prompt module and a network terminal;

[0014] The local prompt module is arranged on the device where the engine is located.

[0015] On the other hand, the engine regeneration early warning control method is applied to an equipment control system of an equipment where the engine is located;

[0016] The equipment where the engine is located is an aerial work platform;

[0017] The preset key functions include the getting-off operation function and the chassis walking function.

[0018] On the other hand, after disabling all functions except the preset key functions in the device where the engine is located, the early warning control method for engine regeneration further includes:

[0019] determining whether the parking regeneration waiting time reaches a second preset time, wherein the second preset time is greater than the first preset time and less than a secondary engine time limit, the secondary engine time limit being a time threshold required for the parking regeneration waiting time to trigger the engine to execute an engine start restriction action;

[0020] If the second preset time is reached, the device control system of the device where the engine is located is locked to prevent the engine state from further deteriorating.

[0021] On the other hand, after locking the device control system of the device where the engine is located, the early warning control method for engine regeneration further includes:

[0022] The control reminder prompts timely parking regeneration.

[0023] In order to solve the above technical problems, the present invention further provides an early warning control device for engine regeneration, comprising:

[0024] a first determination module, configured to determine whether a parking regeneration waiting time reaches a first preset time length after the engine issues a parking regeneration request, wherein the parking regeneration waiting time length refers to the waiting time length from when the engine issues the parking regeneration request to when the parking regeneration is executed; if so, executing the disabling module; if not, executing the regeneration control module;

[0025] The disabling module is used to disable all functions of the device where the engine is located except for preset key functions, so as to enable timely parking regeneration of the engine, wherein the preset key functions are functions required to end the operation and enter the parking regeneration environment;

[0026] The regeneration control module is configured to control the engine to perform parked regeneration in response to a parked regeneration command.

After the engine issues a parking regeneration request, if the parking regeneration waiting time reaches a first preset time length, all functions of the engine except the preset key function are disabled, so that the user can perceive the change in the device status at the first time, and thus control the device to perform parking regeneration of the engine in time, which can avoid further decline of the engine status, thereby helping to improve the engine's working efficiency and reduce maintenance costs.

[0039] The core of the present invention is to provide an engine regeneration early warning control method, device, equipment and readable storage medium. The present invention first sets a preset key function of the equipment. When the engine issues a parking regeneration request, if the parking regeneration waiting time reaches a first preset time, all functions of the engine except the preset key function are disabled, so that the user can perceive the change in the equipment status at the first time, and thus control the equipment to perform the engine parking regeneration in time, which can avoid further decline of the engine status, thereby helping to improve the engine's working efficiency and reduce maintenance costs.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0041] Please refer to Figure 1 , Figure 1 A schematic flow chart of an engine regeneration early warning control method provided by the present invention, the engine regeneration early warning control method comprising:

[0042] After the engine issues a parking regeneration request, determining whether the parking regeneration waiting time reaches a first preset time, wherein the parking regeneration waiting time refers to the waiting time from when the engine issues the parking regeneration request to when the parking regeneration is performed;

[0043] If the threshold is reached, all functions of the engine device except for preset key functions are disabled to allow the engine to be regenerated in a timely manner. The preset key functions are those required to end the operation and enter the parked regeneration environment.

[0044] If not, the engine is controlled to perform parking regeneration in response to a parking regeneration command.

[0045] Specifically, taking into account the technical problems in the above background technology, and considering that disabling the device function can, on the one hand, limit the normal use of the device, and on the other hand, make the user clearly aware that the device needs to perform park regeneration, the embodiment of the present invention intends to protect the engine safety and warn the user by disabling the device function when the engine does not perform park regeneration for a long time after issuing a park regeneration request. In addition, in order to determine "the situation where the engine does not perform park regeneration for a long time after issuing a park regeneration request", the embodiment of the present invention sets a first preset duration of the park regeneration waiting time, which is used as a threshold to determine "the situation where the engine does not perform park regeneration for a long time after issuing a park regeneration request". In the embodiment of the present invention, when the engine issues a park regeneration request, it can be determined whether the park regeneration waiting time reaches the first preset duration, and subsequent actions are triggered based on the determination result.

[0046] The first preset duration can be set independently, and is not limited in this embodiment of the present invention.

[0047] Specifically, the engine control system will trigger a parking regeneration request based on the carbon load of the engine's DPF (Diesel Particulate Filter). For a better explanation of the embodiment of the present invention, please refer to Figure 2 , Figure 2The present invention provides a flow chart of a regeneration control method for an engine control system. When the engine is in normal use, the carbon load X of the engine DPF can be monitored. When X reaches a first carbon load threshold (which can be 62%), the engine enters thermal management mode 1 (i.e., the first thermal management mode). In the first thermal management mode, the time variable T1 is timed. (1) If X is lower than the first carbon load threshold before T1 reaches the first time threshold (which can be 50 hours), the engine is restored to normal use. (2) If X does not exceed the first carbon load threshold to the second carbon load threshold before T1 reaches 50 hours, the engine is restored to normal use. The engine enters thermal management mode 2 (the second thermal management mode) if X reaches the second carbon load threshold (greater than the first carbon load threshold, which can be 78%) before T1 reaches 50 hours, and (3) if X reaches the second carbon load threshold before T1 reaches 50 hours, the engine enters the second thermal management mode; in the second thermal management mode, the time variable T2 is timed, (1) if X is lower than the second carbon load threshold before T2 reaches the second time threshold (which can be 250 hours), the engine enters the first thermal management mode, and (2) if X does not exceed the second carbon load threshold to the third carbon load threshold (greater than the second carbon load threshold) before T2 reaches the second time threshold. The engine control system issues a parking regeneration request. (3) If X reaches the third carbon load threshold before T2 reaches the second time threshold, the engine control system issues a parking regeneration request. After the engine control system issues the parking regeneration request, the time variable T3 is counted. (1) If the engine performs parking regeneration and completes regeneration before T3 reaches the third time threshold (which can be 50H), the engine control system cancels the parking regeneration request. (2) If the engine still does not start parking regeneration when T3 reaches the third time threshold, the engine control system cancels the parking regeneration request. The engine is restricted at the first level (limiting the engine torque to 70%). (3) If the engine performs parking regeneration and completes regeneration before T3 reaches the fourth time threshold (greater than the third time threshold, which can be 75 hours), the engine control system cancels the parking regeneration request. (4) If the engine still does not start parking regeneration when T3 reaches the fourth time threshold, the engine control system will restrict the engine at the second level (limiting engine start). The engine must be regenerated by a professional after-sales service. At this time, it has a higher cost and the damage to the engine is already greater. After the service regeneration, the engine can be restored to normal use.

[0048] The engine may be of various types, for example, a Deutz 74KW engine of AB46RJ Plus, etc., which is not limited in the embodiment of the present invention.

[0049] The present invention provides an early warning control method for engine regeneration. Considering that disabling the device function can, on the one hand, limit the normal use of the device, and on the other hand, enable the user to clearly perceive that the device needs to perform parking regeneration, the present invention first sets a preset key function of the device. After the engine issues a parking regeneration request, if the parking regeneration waiting time reaches a first preset time length, all functions of the engine except the preset key function are disabled, so that the user can perceive the change in the device status at the first time, and thus control the device to perform parking regeneration of the engine in time, which can avoid further decline of the engine status, thereby helping to improve the working efficiency of the engine and reduce maintenance costs.

[0050] Based on the above embodiment:

[0051] As an optional embodiment, the first preset time is less than the first level limit time of the engine;

[0052] The first-level limit time of the engine refers to the time threshold required for the parking regeneration waiting time to trigger the engine to execute the torque limit action.

[0053] Specifically, considering that torque limitation will reduce engine efficiency after all, and that when torque limiting is applied to the engine, the carbon loading X is already high, which causes greater damage to the engine, in order to avoid reducing engine efficiency and damage to the engine, the first preset time length in the embodiment of the present invention can be less than the first-level limit time of the engine, that is, the third time threshold mentioned above.

[0054] Of course, in addition to the first-level limit time, the first preset duration can also be other specific values, which is not limited in the embodiment of the present invention.

[0055] As an optional embodiment, after determining whether the parking regeneration waiting time reaches a first preset time, the engine regeneration early warning control method further includes:

[0056] If it is reached, the control prompter prompts the parking regeneration request.

[0057] Specifically, considering that prompting the parking regeneration request through the prompter is conducive to the staff's further acquisition of the information that "parking regeneration of the engine is required", thereby avoiding further deterioration of the engine state, the embodiment of the present invention can control the prompter to prompt the parking regeneration request after the parking regeneration waiting time reaches a first preset time length.

[0058] As an optional embodiment, the prompter includes a local prompt module and a network terminal;

[0059] The local prompt module is set on the device where the engine is located.

[0060] Specifically, in order to facilitate the operator of the equipment where the engine is located to be informed of the parking regeneration request in the first time, the prompter in the embodiment of the present invention includes a local prompt module arranged in the equipment where the engine is located. In order to facilitate the "operator of the equipment where the engine is located" to miss the prompt information, other staff members can assist and remind the "operator of the equipment where the engine is located", the prompter in the embodiment of the present invention also includes a network terminal, that is, the parking regeneration request can be prompted simultaneously through the local prompt module and the network terminal.

[0061] Of course, in addition to this specific form, the prompter can also be of many other types, which is not limited in the embodiment of the present invention.

[0062] As an optional embodiment, the engine regeneration early warning control method is applied to a device control system of a device where the engine is located;

[0063] The equipment where the engine is located is an aerial work platform;

[0064] The preset key functions include getting off the vehicle and chassis traveling.

[0065] Specifically, considering that the aerial work platform itself uses an engine and the engine has a regeneration demand and a regeneration warning demand, the engine regeneration warning control method in the embodiment of the present invention is applied to the equipment control system of the aerial work platform, that is, in the aerial work platform, the equipment control system can be Figure 2 Based on the control logic of the engine control system, it assists in early warning control, can help staff to perform parking regeneration in time and prevent the engine condition from deteriorating.

[0066] Specifically, the device control system may be various specific types of controllers, such as an ECU (Electronic Control Unit), etc., which is not limited in the embodiment of the present invention.

[0067] Among them, for the aerial work platform, when the engine issues a parking regeneration request, in order to perform parking regeneration, the "getting off operation function and chassis walking function" are functions that the staff need to use in order to enter the environment required for parking regeneration. Therefore, in the embodiment of the present invention, the "getting off operation function and chassis walking function" are used as the preset key functions of the aerial work platform.

[0068] Of course, the preset key functions of the aerial work platform may also be in other forms, and for different devices, different preset key functions may be set according to actual needs, which is not limited in the embodiment of the present invention.

[0069] As an optional embodiment, after disabling all functions except preset key functions in the device where the engine is located, the early warning control method for engine regeneration further includes:

[0070] S204: Determining whether the parking regeneration waiting time reaches a second preset time, wherein the second preset time is greater than the first preset time and less than the secondary engine time limit, which refers to the time threshold required for the parking regeneration waiting time to trigger the engine to execute the engine start restriction action;

[0071] S205: If the second preset time is reached, the device control system of the device where the engine is located is locked to prevent the engine state from further deteriorating.

[0072] Specifically, to better illustrate the embodiments of the present invention, please refer to Figure 3 , Figure 3 This is a flow chart of another early warning control method for engine regeneration provided by the present invention, wherein S201 to S203 correspond to S101 to S103 respectively.

[0073] Specifically, considering that once the engine enters the second-level restriction, it not only means that the engine has been seriously damaged, but also the engine must be regenerated through expensive service regeneration after entering the second-level restriction, in order to prevent the user from continuing to perform operations with low torque requirements after the first-level restriction (i.e., torque restriction), thereby inadvertently causing the engine to enter the second-level restriction, in an embodiment of the present invention, the device control system of the device where the engine is located can be locked when the parking regeneration waiting time reaches a second preset time (the second preset time is greater than the first preset time, and the second preset time is less than the second-level restriction time of the engine, and the second-level restriction time is also the fourth time threshold mentioned above). In this case, the device where the engine is located is theoretically unable to perform any operation, and it is necessary to contact the after-sales personnel of the equipment manufacturer to unlock the device control system and perform parking regeneration (which is less expensive than service regeneration) to restore the engine to normal state.

[0074] Among them, since the second preset time is less than the secondary limit time of the engine, the engine is prevented from entering the secondary limit state (where service regeneration is required), thereby reducing damage to the engine and lowering the regeneration cost.

[0075] The second preset duration can be set independently, and is not limited in this embodiment of the present invention.

[0076] As an optional embodiment, after locking the equipment control system of the equipment where the engine is located, the engine regeneration early warning control method further includes:

[0077] The control reminder prompts timely parking regeneration.

[0078] Specifically, considering that after locking the equipment control system of the equipment where the engine is located, further prompts are given through the prompter to facilitate the staff to promptly understand the reason for locking and start parking regeneration as soon as possible, in an embodiment of the present invention, after locking the equipment control system of the equipment where the engine is located, the prompter can also be controlled to prompt to perform parking regeneration in time.
