[0002] Engines are widely used in various industries. As the running time increases, the engine needs to be regenerated in order to restore its performance. The engine regeneration includes parking regeneration, which is the regeneration performed when the entire equipment stops working (only the engine is started).

[0039] The core of the present invention is to provide an engine regeneration early warning control method, device, equipment and readable storage medium. In the present invention, a preset key function of the equipment is first set. After 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 of the equipment status at the first time, and thus control the equipment in time to perform the parking regeneration of the engine, which can avoid further decline of the engine status, thereby helping to improve the working efficiency of the engine and reduce maintenance costs.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

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

[0042] After the engine issues a parking regeneration request, determining whether the parking regeneration waiting time reaches a first preset time length, 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;

[0043] If it is reached, all functions except the preset key functions in the device where the engine is located are disabled so as to timely perform parking regeneration on the engine, wherein the preset key functions refer to the functions required to end the operation and enter the parking regeneration environment;

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

[0045] Specifically, in view of the technical problems in the above background technology, and in combination with the consideration 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 parking regeneration, therefore, in an embodiment of the present invention, when the engine does not perform parking regeneration for a long time after issuing a parking regeneration request, the engine safety is protected and the user is warned by disabling the device function. In addition, in order to determine "the situation where the engine does not perform parking regeneration for a long time after issuing a parking regeneration request", a first preset duration of the parking regeneration waiting time is set in the embodiment of the present invention, and this is used as a threshold to determine "the situation where the engine does not perform parking regeneration for a long time after issuing a parking regeneration request". In the embodiment of the present invention, when the engine issues a parking regeneration request, it can be determined whether the parking regeneration waiting time reaches the first preset duration, and subsequent actions are triggered based on the determination result.

[0046] The first preset duration may be set independently, and the embodiment of the present invention does not limit this.

[0047] Specifically, the engine control system will trigger the generation of a parking regeneration request based on the carbon load of the DPF (Diesel Particulate Filter) of the engine. For a better description 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 of 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 a 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 exceeds the second carbon load threshold (greater than the first carbon load threshold, which can be 78%) before T1 reaches 50 hours. (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. (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 enters the first thermal management mode. (1) If the engine performs parking regeneration and completes regeneration before T3 reaches the third time threshold (which can be 50 hours), 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 serviced and regenerated by a professional after-sales service. At this time, it has a high cost and the damage to the engine is already large. 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 of the device state at the first time, thereby controlling the device to perform parking regeneration of the engine in time, and avoiding further decline of the engine state, which is beneficial to improving the working efficiency of the engine and reducing maintenance costs.

[0050] Based on the above embodiments:

[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 the engine efficiency after all, and when the engine is torque limited, the carbon loading X is already high, the damage to the engine is greater. Therefore, in order to avoid reducing the engine efficiency and reduce the damage to the engine, the first preset time 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 may 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 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 "need to perform parking regeneration on the engine", thereby avoiding further deterioration of the engine state, the prompter can be controlled in the embodiment of the present invention 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 arranged 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 reminder in the embodiment of the present invention includes a local reminder module arranged on the equipment where the engine is located. In order to facilitate the "operator of the equipment where the engine is located" to miss the reminder information, other staff members can assist and remind the "operator of the equipment where the engine is located", the reminder in the embodiment of the present invention also includes a network terminal, that is, the parking regeneration request can be prompted through the local reminder module and the network terminal at the same time.

[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 early warning control method of engine regeneration 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 the getting-off operation function and the chassis walking function.

[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, which can help staff to perform parking regeneration in time and prevent the engine condition from deteriorating.

[0066] Specifically, the device control system may be a variety of 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 sends a parking regeneration request, in order to perform parking regeneration, the "getting off the vehicle operation function and the 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 the vehicle operation function and the 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 embodiments of the present invention.

[0069] As an optional embodiment, after disabling each function except the preset key function 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 the second preset time is less than the secondary limit time of the engine, and the secondary limit time of the engine refers to the time threshold required for the parking regeneration waiting time to trigger the engine to execute the engine start limit 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, in order 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 avoid the user continuing to perform operations with lower torque requirements after the first-level restriction (that is, torque limitation), 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 theoretically cannot 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 (the cost is lower than service regeneration) to restore the engine to normal.

[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 may be set independently, and the embodiment of the present invention does not limit this.

[0076] As an optional embodiment, after locking the equipment control system of the equipment where the engine is located, the early warning control method for engine regeneration 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 prompting is performed 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.

If it reaches the time length, the disabling module 42 is executed; if it does not reach the time length, the regeneration control module 43 is executed;

[0081] A disabling module 42 is used to disable various functions of the device where the engine is located except for preset key functions, so as to timely perform parking regeneration on the engine, wherein the preset key functions refer to functions required for ending the operation and entering the parking regeneration environment;
