Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas post-processing, and in particular to a method, device and electronic equipment for processing particulate matter. Background Art

[0002] At present, for non-road stage IV engineering machinery models with more transient working conditions, the operating conditions are also more complicated. For example, when operating at maximum efficiency, the exhaust temperature in front of the DPF (Diesel Particulate Filter) is high, and carbon deposits grow slowly; but when operating at partial efficiency, the exhaust temperature in front of the DPF is low, and carbon deposits grow rapidly. Once the vehicle engine is in a condition where carbon deposits grow rapidly for a long time, it will lead to frequent regeneration times and increase the risk of oil dilution. Therefore, it is difficult to accurately control the vehicle to regenerate the DPF in the relevant technology, resulting in poor results in eliminating carbon particulate matter in the DPF.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all 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.

[0019] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below: DOC: Diesel Oxide Catalyst, installed in front of DPF (particulate matter filter), is used to oxidize NO (nitrogen monoxide) in exhaust gas into NO2 (nitrogen dioxide), while increasing the exhaust gas temperature, assisting the normal operation of DPF (particulate matter filter) and SCR (selective catalytic reduction system).

[0020] DPF: Diesel Particulate Filter, used to capture particulate matter in exhaust gas. When the mass of captured particulate matter reaches a certain level, passive regeneration or active regeneration is required to restore the DPF's (particulate matter filter) ability to capture particulate matter.

[0021] DPF regeneration: Utilizes the reaction between NO2 (nitrogen dioxide) and C (carbon) produced in DOC (oxidation catalytic converter) to eliminate C (carbon) in DPF (particulate matter filter).

[0022] Parking regeneration: The vehicle is parked in place and diesel is injected into the exhaust pipe. The diesel is oxidized in the DOC and releases heat, burning the carbon particles inside the DPF.

[0023] Driving regeneration: During driving, diesel is injected into the exhaust pipe. The diesel is oxidized in the DOC and releases heat, burning the carbon particles inside the DPF.

[0024] The present invention is described below in conjunction with preferred implementation steps. Figure 1 The process of the method for treating particulate matter provided in the embodiment of the present application is as follows Figure 1 ,like Figure 1 As shown, the method comprises the following steps: Step S101, obtaining information on the number of times target particulate matter in a particulate matter trap is eliminated within a preset time period, wherein the particulate matter trap is a machine in a target vehicle for trapping target particulate matter, and the target particulate matter is particulate matter in exhaust gas emitted by the target vehicle.

[0025] For example, the number of driving regeneration and parking regeneration performed by the engine of the target vehicle within a certain period of time (corresponding to the above-mentioned preset time length) is identified (corresponding to the above-mentioned number of times the target particulate matter in the particulate matter trap is eliminated).

[0026] For example, the target particulate matter may be C (carbon) particulate matter, and the number of regenerations may represent information on the number of times C (carbon) in a DPF (particulate matter trap) is eliminated.

[0027] Step S102 : determining the state information of the target particulate matter in the engine of the target vehicle according to the number of times the target particulate matter in the particulate matter trap is eliminated within a preset time period.

[0028] For example, based on the number of driving regeneration and parking regeneration performed by the engine within a certain period of time (corresponding to the above-mentioned preset time length) (corresponding to the above-mentioned number of times of eliminating the target particulate matter in the particulate matter trap), the carbon deposition state (i.e., the state information of the target particulate matter) of the engine (corresponding to the above-mentioned engine of the target vehicle) is identified. Moreover, the engine carbon deposition state (i.e., the state information of the target particulate matter) can be divided into three states: excessive carbon deposition, balanced carbon deposition, and less carbon deposition.

[0029] Step S103, according to the state information of the target particulate matter in the engine, the target particulate matter in the particulate matter trap is eliminated, and the regeneration process of the particulate matter trap is realized.

[0030] For example, the regeneration measures may be adjusted according to the identified carbon deposit state (ie, state information of the target particulate matter) of the engine (corresponding to the engine of the target vehicle mentioned above).

[0031] Through the above steps S101 to S103, by identifying the number of regenerations performed by the target vehicle within a certain period of time (i.e., the preset duration) (i.e., the number of times the target particulate matter in the particulate matter trap is eliminated), it is identified which carbon deposition state the engine of the target vehicle is in (i.e., the state information of the target particulate matter), and then according to the carbon deposition state of the engine, the regeneration measures (i.e., the elimination treatment of the target particulate matter in the particulate matter trap) are determined, so that the vehicle can be accurately controlled to regenerate the DPF, thereby improving the effect of eliminating carbon particulate matter in the DPF.

[0032] Optionally, in the particulate matter processing method provided in the embodiment of the present application, obtaining information on the number of times target particulate matter in the particulate matter collector is eliminated within a preset time length includes: obtaining the first number of times the target particulate matter in the particulate matter collector is eliminated while the target vehicle is driving within the preset time length; obtaining the second number of times the target particulate matter in the particulate matter collector is eliminated while the target vehicle is stopping within the preset time length; based on the first number and the second number, obtaining information on the number of times the target particulate matter in the particulate matter collector is eliminated within the preset time length.

[0033] For example, the number of driving regenerations (corresponding to the first number mentioned above) and the number of parking regenerations (corresponding to the second number mentioned above) performed by the engine within a certain period of time (corresponding to the preset period of time mentioned above) can be identified, and then the number of driving regenerations (corresponding to the first number mentioned above) and the number of parking regenerations (corresponding to the first number mentioned above) performed by the engine within a certain period of time are added together to obtain the number of regenerations of the engine within the time period (corresponding to the preset period of time mentioned above) (corresponding to the number of times the target particulate matter in the particulate matter collector is eliminated).

[0034] Through the above scheme, the number of regenerations of the target vehicle within a certain period of time can be quickly and accurately obtained.

[0035] Optionally, in the particulate matter processing method provided in the embodiment of the present application, determining the state information of the target particulate matter in the engine of the target vehicle based on the number of times the target particulate matter in the particulate matter collector is eliminated within a preset time period includes: judging whether the number of times the target particulate matter in the particulate matter collector is eliminated within the preset time period is greater than a preset number; if the number of times the target particulate matter in the particulate matter collector is eliminated within the preset time period is greater than the preset number, then determining that the state of the target particulate matter in the engine of the target vehicle is a first state, wherein the first state indicates that the mass of the target particulate matter in the engine of the target vehicle is greater than a preset mass; if the number of times the target particulate matter in the particulate matter collector is eliminated within the preset time period is not greater than the preset number, then judging whether the number of times the target particulate matter in the particulate matter collector is eliminated within the preset time period is less than a preset number, and obtaining a judgment result; based on the judgment result, determining the state information of the target particulate matter in the engine of the target vehicle.

[0036] For example, the above-mentioned preset number of times can be 3 times. When it is detected that the target vehicle has been regenerated 5 times within a certain period of time (corresponding to the above-mentioned preset time length), the number of regenerations of the target vehicle within a certain period of time (corresponding to the above-mentioned preset time length) is greater than the preset number of 3 times. Therefore, it can be determined that the engine of the vehicle (corresponding to the above-mentioned target vehicle) is in a state of excessive carbon deposits (corresponding to the above-mentioned first state); if it is detected that the number of regenerations of the target vehicle within a certain period of time (corresponding to the above-mentioned preset time length) is not greater than the preset number of 3 times, it can be determined whether the number of regenerations of the target vehicle within a certain period of time (corresponding to the above-mentioned preset time length) is less than the preset number of 3 times, and then based on the judgment result, it is determined what kind of carbon deposit state the engine of the vehicle (corresponding to the above-mentioned target vehicle) is in.

[0037] Through the above scheme, the excessive carbon deposit state of the engine can be easily determined according to the number of regenerations of the target vehicle within a certain period of time.

[0038] Optionally, in the particulate matter processing method provided in the embodiment of the present application, determining the state information of the target particulate matter in the engine of the target vehicle based on the judgment result includes: if the judgment result indicates that the number of times the target particulate matter in the particulate matter collector is eliminated within a preset time length is less than a preset number, then determining that the state of the target particulate matter in the engine of the target vehicle is a second state, wherein the second state indicates that the mass of the target particulate matter in the engine of the target vehicle is less than a preset mass; if the judgment result indicates that the number of times the target particulate matter in the particulate matter collector is eliminated within the preset time length is not less than a preset number, then determining that the state of the target particulate matter in the engine of the target vehicle is a third state, wherein the third state indicates that the mass of the target particulate matter in the engine of the target vehicle is equal to the preset mass.

[0039] For example, if the target vehicle regenerates 2 times within a certain period of time (corresponding to the above-mentioned preset time length), it can be determined that the target vehicle regenerates less than the preset number of times 3 within a certain period of time (corresponding to the above-mentioned preset time length). Therefore, the engine of the vehicle (corresponding to the above-mentioned target vehicle) is in a state with less carbon deposits (corresponding to the above-mentioned second state). If the target vehicle regenerates 3 times within a certain period of time (corresponding to the above-mentioned preset time length), it can be determined that the target vehicle regenerates equal to the preset number of times 3 within a certain period of time (corresponding to the above-mentioned preset time length). Therefore, the engine of the vehicle (corresponding to the above-mentioned target vehicle) is in a carbon deposit balance state (corresponding to the above-mentioned third state).

[0040] Through the above scheme, the carbon deposit-less state and carbon deposit-balanced state of the engine can be quickly and accurately determined.

[0041] For example, Figure 2 The process of the method for treating particulate matter provided in the embodiment of the present application is as follows Figure 2 ,like Figure 2 As shown, the method for processing particulate matter provided in the embodiment of the present application specifically includes the following steps: Step S201, determining the state information of the target particulate matter in the engine of the target vehicle; Step S202, if the state of the target particulate matter in the engine is the first state, the temperature of the particulate matter trap is increased, and the target particulate matter in the particulate matter trap is eliminated; Step S203, if the state of the target particulate matter in the engine is the second state, lowering the temperature of the particulate matter trap and performing a process of eliminating the target particulate matter in the particulate matter trap; Step S204: if the state of the target particulate matter in the engine is the third state, it is prohibited to adjust the temperature of the particulate matter trap, and the target particulate matter in the particulate matter trap is eliminated.

[0042] For example, when it is determined that the vehicle is in a state of excessive carbon deposits (corresponding to the first state mentioned above), the regeneration measures are adjusted to increase the exhaust temperature before the DPF (particulate matter trap) to improve the carbon removal effect; when it is determined that the vehicle is in a state of less carbon deposits (corresponding to the second state mentioned above), the regeneration measures are adjusted to reduce the exhaust temperature before the DPF (particulate matter trap) to reduce the carbon removal effect; when it is determined that the vehicle is in a balanced carbon deposit state (corresponding to the third state mentioned above), the regeneration measures are maintained.

[0043] Through the above-mentioned scheme, the regeneration measures of the DPF can be adjusted quickly and accurately.

[0044] For example, Figure 3 The process of the method for treating particulate matter provided in the embodiment of the present application is as follows Figure 3 , specifically, the following steps are included: S301, obtaining information on the number of times target particles in a particle collector are eliminated within a preset time period; S302, determining the state information of the target particulate matter in the engine of the target vehicle according to the number of times the target particulate matter in the particulate matter trap is eliminated within a preset time period; S303, determining that the carbon deposit is less; S304, reducing the DPF front exhaust temperature; S305, determining that the carbon deposition is in a balanced state; S306, maintenance regeneration measures; S307, determining that there is excessive carbon deposition; S308: Increase the DPF front exhaust temperature.

[0045] In the embodiment of the present application, the number of driving regeneration and parking regeneration performed by the engine within a preset time is first identified, and then based on the driving and parking regeneration information within the preset time, it is determined whether the engine is in one of the three states of excessive carbon deposits (corresponding to the first state mentioned above), balanced carbon deposits (corresponding to the third state mentioned above), and less carbon deposits (corresponding to the second state mentioned above): when it is determined to be in the state of excessive carbon deposits (corresponding to the first state mentioned above), the regeneration measures are adjusted to increase the exhaust temperature before the DPF (particulate matter trap), improve the carbon removal effect, reduce the number of regenerations, and thus reduce the risk of oil dilution; when it is determined to be in the state of less carbon deposits (corresponding to the second state mentioned above), the regeneration measures are adjusted to reduce the exhaust temperature before the DPF (particulate matter trap), reduce the carbon removal effect, and reduce the amount of fuel injection, thereby improving economy; when it is determined to be in the state of balanced carbon deposits (corresponding to the third state mentioned above), the regeneration measures are maintained.

[0046] In this embodiment, by analyzing the driving regeneration and parking regeneration within a certain period of time, the injection amount of the post-injection is changed, the temperature of the DPF (particulate matter trap) is controlled, the carbon removal effect is adjusted in real time, the oil dilution risk is reduced or the economy is improved. This control method can improve the adaptability of the engine in actual application.

[0047] In addition, in this embodiment, the regeneration status of the engine is collected in real time to determine whether the current regeneration temperature is suitable. In the case of excessive carbon deposition and excessive regeneration times during driving, the carbon removal ability is improved to reduce the number of regenerations, thereby reducing the risk of oil dilution. In the case of less carbon deposition, the amount of post-injection fuel can be reduced to improve economy.

[0048] In summary, the method for processing particulate matter provided in the embodiment of the present application obtains information on the number of times target particulate matter in a particulate matter collector is eliminated within a preset time period, wherein the particulate matter collector is a machine in a target vehicle for capturing target particulate matter, and the target particulate matter is particulate matter in the exhaust gas emitted by the target vehicle; based on the information on the number of times target particulate matter in the particulate matter collector is eliminated within a preset time period, status information of target particulate matter in the engine of the target vehicle is determined; based on the status information of the target particulate matter in the engine, the target particulate matter in the particulate matter collector is eliminated, and a regeneration process of the particulate matter collector is implemented, thereby solving the problem in the related art that it is difficult to accurately control the vehicle to perform DPF regeneration, resulting in poor effect of eliminating carbon particulate matter in the DPF. By identifying the number of regenerations performed by the target vehicle within a certain period of time (i.e., the preset duration) (i.e., the number of times the target particulate matter in the particulate matter collector is eliminated), the carbon deposition state of the engine of the target vehicle (i.e., the state information of the target particulate matter) is identified, and then the regeneration measures (i.e., the elimination treatment of the target particulate matter in the particulate matter collector) are determined according to the carbon deposition state of the engine, so that the vehicle can be accurately controlled to regenerate the DPF, thereby improving the effect of eliminating carbon particulate matter in the DPF.

[0049] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0050] The present application also provides a particle processing device. It should be noted that the particle processing device of the present application can be used to execute the particle processing method provided in the present application. The particle processing device provided in the present application is introduced below.

[0052] Specifically, the first acquisition unit 401 is used to acquire information on the number of times target particles in a particle trap are eliminated within a preset time period, wherein the particle trap is a machine in a target vehicle for capturing target particles, and the target particles are particles in exhaust gas emitted by the target vehicle; A first determining unit 402 is used to determine the state information of the target particulate matter in the engine of the target vehicle according to the number of times the target particulate matter in the particulate matter trap is eliminated within a preset time period; The first processing unit 403 is used to eliminate the target particulate matter in the particulate matter trap according to the state information of the target particulate matter in the engine, and realize the regeneration process of the particulate matter trap.

By identifying the number of regenerations performed by the target vehicle within a certain period of time (i.e., the preset duration) (i.e., the number of times the target particulate matter in the particulate matter collector is eliminated), the carbon deposition state of the engine of the target vehicle (i.e., the state information of the target particulate matter) is identified, and then the regeneration measures (i.e., the elimination treatment of the target particulate matter in the particulate matter collector) are determined according to the carbon deposition state of the engine, so that the vehicle can be accurately controlled to regenerate the DPF, thereby improving the effect of eliminating carbon particulate matter in the DPF.
