Description

Technical Field

[0001] This invention relates to a method and apparatus for temperature-controlled cleaning of fuel tank circuit cleaning fluid based on qualitative analysis of the fuel tank environment, belonging to the field of fuel tank cleaning technology. Background Technology

[0002] The cleanliness of a car's fuel tank and fuel lines directly affects engine performance and fuel efficiency. Carbon deposits accumulated in the fuel tank and fuel lines not only increase fuel consumption but may also cause engine malfunctions, such as fuel injector blockage. Therefore, cleaning carbon deposits from a car's fuel tank and fuel lines is particularly important.

[0003] Traditional methods for cleaning fuel tanks and fuel lines mainly include chemical cleaning, water washing, and mechanical cleaning. While water washing is environmentally friendly, it is limited by the structure and materials of the fuel tank and fuel lines, making it difficult to completely drain the water and resulting in poor cleaning. Mechanical cleaning requires disassembling the fuel tank, which is complex and costly. Therefore, chemical cleaning is currently the most common method for cleaning fuel tanks and fuel lines. Although chemical cleaning can thoroughly remove carbon deposits in the fuel tank and fuel lines, it poses potential damage to the fuel tank and fuel system and may cause corrosion. As a result, current methods for cleaning fuel tanks and fuel lines suffer from poor selection of cleaning modes and low cleaning efficiency. Summary of the Invention

[0004] This invention provides a method, apparatus, and computer-readable storage medium for temperature-controlled cleaning of fuel tank oil circuits based on qualitative analysis of the fuel tank environment. Its main purpose is to solve the problems of poor selectivity of cleaning modes and low cleaning efficiency in current fuel tank oil circuit cleaning.

[0007] A qualitative environmental test was conducted on the pre-constructed fuel tank to be cleaned to obtain the initial carbon deposit quality of the fuel tank to be cleaned.

[0008] The system receives a user-inputted carbon deposit cleaning mode and extracts a carbon deposit cleaning mode formula from a pre-built set of carbon deposit cleaning mode formulas. This set of formulas includes a carbon deposit cleaning speed formula and a carbon deposit cleaning flexibility formula, as shown below:

[0009]

[0010] Where s represents the carbon deposit cleaning rate within the carbon deposit cleaning time t, t represents the carbon deposit cleaning time, c0 represents the initial carbon deposit mass, and c t The remaining carbon deposit mass is represented by r, the carbon deposit cleaning flexibility is represented by m, the number of curve sampling points is represented by i, and the number of curve sampling points is represented by k. i This represents the slope of the i-th curve sampling point. Let α represent the average slope of m curve sampling points, and let β represent the slope exponent and β represent the velocity exponent.

[0011] The initial time-carbon deposit curve set is obtained based on the initial carbon deposit quality and multiple sets of time-carbon deposit curve sets. The target time-carbon deposit curve is identified in the initial time-carbon deposit curve set according to the carbon deposit cleaning mode formula and the preset unit test duration.

[0012] Based on the carbon deposit cleaning mode formula, extract the carbon deposit cleaning cutoff point from the target time-carbon deposit curve, and identify the cutoff cleaning time and cutoff carbon deposit quality corresponding to the carbon deposit cleaning cutoff point.

[0013] Determine whether the cutoff carbon deposit mass is less than a preset carbon deposit mass threshold;

[0014] If the cutoff carbon deposit quality is not less than the carbon deposit quality threshold, then the initial carbon deposit quality is updated using the cutoff carbon deposit quality, and the steps described above for obtaining the initial time-carbon deposit curve set based on the initial carbon deposit quality and multiple sets of time-carbon deposit curve sets are returned.

[0015] If the cutoff carbon deposit quality is less than the carbon deposit quality threshold, then all carbon deposit cleaning cutoff points are summarized to obtain a carbon deposit cleaning cutoff point set. The carbon deposit cleaning cutoff point set is sorted to obtain a carbon deposit cleaning cutoff point sequence.

[0048] If the carbon deposit cleaning mode formula is a carbon deposit cleaning speed formula, then the unit test duration is used as the carbon deposit cleaning duration. The initial carbon deposit mass and the remaining carbon deposit mass are extracted from the initial time-carbon deposit curve segment. Based on the carbon deposit cleaning duration, the initial carbon deposit mass and the remaining carbon deposit mass, the carbon deposit cleaning speed is calculated using the carbon deposit cleaning mode formula to obtain the carbon deposit cleaning speed set.

[0049] Extract the maximum carbon deposit cleaning speed from the set of carbon deposit cleaning speeds, and identify the target time-carbon deposit curve corresponding to the maximum carbon deposit cleaning speed;

[0057] t'=t+Δt

[0058] Where t' represents the extension duration and Δt represents the sampling interval duration;

[0059] Based on the extended duration, extract the extended time-carbon deposition curve segment set from the initial time-carbon deposition curve set;

[0087] To address the above problems, the present invention also provides an electronic device, the electronic device comprising:

[0088] At least one processor; and,

[0089] A memory communicatively connected to the at least one processor; wherein,

[0090] The memory stores instructions that can be executed by the at least one processor, which execute the instructions to implement the above-described method for temperature-controlled cleaning of fuel tank circuit cleaning fluid based on qualitative analysis of the fuel tank environment.

[0091] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the above-described method for temperature-controlled cleaning of fuel tank circuit cleaning fluid based on qualitative analysis of the fuel tank environment.

[0092] Compared to the problems described in the background art, the embodiments of the present invention require temperature-controlled cleaning tests on fuel tanks with different carbon deposit qualities and different test temperatures. Therefore, it is necessary to first obtain a batch test fuel tank set, and then sequentially extract batch test fuel tanks from the batch test fuel tank set. This allows for temperature-controlled cleaning tests on the batch test fuel tanks according to a preset test temperature set, resulting in multiple sets of time-carbon deposit curves corresponding to each batch test fuel tank. At this point, a qualitative environmental test of the fuel tank to be cleaned is required to obtain the initial carbon deposit quality of the fuel tank to be cleaned. Since there are multiple carbon deposit cleaning modes, it is necessary to receive user... The input carbon deposit cleaning mode is used, and a carbon deposit cleaning mode formula is extracted from a pre-constructed set of carbon deposit cleaning mode formulas. Since the carbon deposit cleaning mode formula is determined by the initial carbon deposit quality, an initial time-carbon deposit curve set is first obtained based on the initial carbon deposit quality and multiple sets of time-carbon deposit curve sets. Then, a target time-carbon deposit curve is identified from the initial time-carbon deposit curve set based on the carbon deposit cleaning mode formula and a preset unit test duration. Since the target time-carbon deposit curve only best matches the carbon deposit cleaning mode within a unit test duration, it is necessary to further refine the calculation based on the input carbon deposit cleaning mode formula. The carbon buildup cleaning mode formula extracts the carbon buildup cleaning cutoff point from the target time-carbon buildup curve, then identifies the cutoff cleaning time and the cutoff carbon buildup quality corresponding to the cutoff point. To determine whether cleaning is complete, it is necessary to check whether the cutoff carbon buildup quality is less than a preset carbon buildup quality threshold. If the cutoff carbon buildup quality is not less than the carbon buildup quality threshold, the initial carbon buildup quality needs to be updated using the cutoff carbon buildup quality, and the initial time-carbon buildup curve set and carbon buildup cleaning cutoff point need to be re-acquired. If the cutoff carbon buildup quality is less than the carbon buildup quality threshold, it indicates that carbon buildup cleaning has been completed, and at this time... By summarizing all carbon deposit cleaning cutoff points, a set of carbon deposit cleaning cutoff points is obtained. This set is then sorted to obtain a sequence of carbon deposit cleaning cutoff points. At this point, it is only necessary to identify the carbon deposit cleaning temperature sequence corresponding to the carbon deposit cleaning cutoff point sequence, and perform temperature-controlled cleaning of the fuel tank and fuel system according to this sequence. Therefore, the main purpose of the fuel tank and fuel system temperature-controlled cleaning method, device, electronic equipment, and computer-readable storage medium proposed in this invention, based on qualitative analysis of the fuel tank environment, is to solve the problems of poor selectivity of cleaning modes and low cleaning efficiency in current fuel tank and fuel system cleaning methods.

[0096] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0097] This application provides a method for temperature-controlled cleaning of fuel tank and fuel system cleaning fluid based on qualitative analysis of the fuel tank environment.

[0098] Example 1:

[0099] Reference Figure 1 The diagram shown is a flowchart illustrating a fuel tank and fuel system temperature-controlled cleaning method based on qualitative analysis of the fuel tank environment, according to an embodiment of the present invention. In this embodiment, the fuel tank and fuel system temperature-controlled cleaning method based on qualitative analysis of the fuel tank environment includes:

[0100] S1. Obtain a batch test oil tank set, extract batch test oil tanks sequentially from the batch test oil tank set, and perform temperature-controlled cleaning tests on the batch test oil tanks according to the preset test temperature set to obtain multiple sets of time-carbon deposition curves corresponding to each batch test oil tank.

[0101] Explained, the "batch test tank set" refers to a collection of multiple batch test tanks. The batch test tanks refer to a collection of tanks tested under the same carbon deposit mass and different test temperatures. The number of batches in the batch test tanks is the same as the number of carbon deposit mass tests, and the number of test tanks in each batch test tank is the same as the number of test temperatures. For example, when the test temperatures are 30℃, 35℃, 40℃, and 45℃, and the carbon deposit mass is 100g, 200g, 300g, 400g, and 500g, the batch test tank set can be divided into: Batch 1 test tank set (all carbon deposit mass is 100g), Batch 2 test tank set, and so on. The test oil tank sets are divided into five batches: the first batch (each with 200g of carbon deposits), the second batch (each with 300g of carbon deposits), the third batch (each with 400g of carbon deposits), and the fifth batch (each with 500g of carbon deposits). The first batch of test oil tank sets includes the first test oil tank (test temperature 30℃), the second test oil tank (test temperature 35℃), the third test oil tank (test temperature 40℃), and the fourth test oil tank (test temperature 45℃). The test temperature settings for the second, third, fourth, and fifth batches of test oil tank sets are similar.

[0102] Furthermore, the temperature-controlled cleaning test refers to performing temperature-controlled cleaning tests at different test temperatures on each test tank within the batch of test tanks. The multiple sets of time-carbon deposit curves refer to the sets of time-carbon deposit curves corresponding to each batch of test tanks, and the time-carbon deposit curve sets refer to the collection of curves showing the change in real-time carbon deposit quality over time for each test tank within the batch of test tanks during the temperature-controlled cleaning test.

[0103] In this embodiment of the invention, obtaining the batch test tank set includes:

[0104] Obtain the test temperature data and use the test temperature data as the batch oil tank number;

[0105] Obtain the test carbon deposit quality sequence, and extract the test carbon deposit quality sequentially from the test carbon deposit quality sequence.

[0106] The batch of test oil tanks was obtained based on the batch number of oil tanks and the test carbon deposit quality.

[0107] The batch test tanks corresponding to each test carbon deposit quality are summarized to obtain the batch test tank set.

[0108] Understandably, the number of test temperatures refers to the number of test temperatures, and the number of batch oil tanks refers to the number of test oil tanks in a batch of test oil tanks. The test carbon deposit mass sequence refers to the carbon deposit mass sequence used for testing, and the test carbon deposit mass sequence can be: 100g, 200g, 300g, 400g, 500g, that is, the carbon deposit mass of each test oil tank in the batch of test oil tanks is set to 100g, 200g, 300g, 400g, and 500g respectively when the test begins.

[0109] In this embodiment of the invention, the step of performing temperature-controlled cleaning tests on the batch of test tanks according to a preset test temperature set to obtain multiple sets of time-carbon deposition curves corresponding to each batch of test tanks includes:

[0110] The test tanks were sequentially extracted from the batch of test tanks.

[0111] The test temperatures are extracted sequentially from the set of test temperatures.

[0112] Prepare a constant-temperature cleaning solution based on the test temperature and the pre-constructed oil tank and oil circuit cleaning solution;

[0113] The constant temperature cleaning fluid is used to clean the oil tank under test, and the real-time carbon deposit quality is measured according to the preset measurement unit time.

[0114] Based on the real-time carbon deposit quality, a time-carbon deposit curve of the fuel tank under test is plotted to obtain a set of time-carbon deposit curves for the batch of fuel tanks tested.

[0115] By summarizing the time-carbon deposit curve sets corresponding to each batch of tested fuel tanks, multiple sets of time-carbon deposit curve sets are obtained.

[0116] Explained, the constant temperature cleaning fluid refers to a fuel tank and fuel system cleaning fluid with a constant temperature at the test temperature, and the fuel tank and fuel system cleaning fluid is a car fuel tank and fuel system cleaning fluid.

[0117] Furthermore, the measurement unit duration refers to the time interval used to collect real-time carbon deposit quality data. For example, during the cleaning test of the fuel tank under test, carbon deposit quality can be measured according to the measurement unit duration. When the measurement unit duration is 1 minute, real-time carbon deposit quality can be measured at time points such as the 1st minute, 2nd minute, 3rd minute, etc., during the cleaning test. The time-carbon deposit curve refers to a curve with cleaning time as the independent variable and carbon deposit quality as the dependent variable.

[0118] S2. Perform a qualitative environmental test on the pre-constructed fuel tank to be cleaned to obtain the initial carbon deposit quality of the fuel tank to be cleaned.

[0119] Explained, the "fuel tank to be cleaned" refers to the fuel tank that currently requires carbon deposit cleaning, and the "qualitative environmental test of the fuel tank" refers to measuring the current carbon deposit quality of the fuel tank to be cleaned. The "initial carbon deposit quality" refers to the carbon deposit quality of the fuel tank to be cleaned before the fuel tank cleaning process.

[0120] In this embodiment of the invention, the step of performing qualitative environmental testing on the pre-constructed fuel tank to be cleaned to obtain the initial carbon deposit quality of the fuel tank to be cleaned includes:

[0121] The performance of the oil tank to be cleaned is tested according to a preset set of performance indicators to obtain a set of performance test values.

[0122] Obtain a standard performance value set, and calculate a performance test difference set based on the performance test value set and the standard performance value set;

[0123] Based on the performance test difference set, the initial carbon deposit mass is calculated using a pre-constructed carbon deposit prediction formula, wherein the carbon deposit prediction formula is as follows:

[0124]

[0125] Where j represents the performance index number, J represents the total number of performance indices, and q j x represents the carbon deposition ratio coefficient of the j-th performance index. j This represents the performance test difference for the j-th performance metric.

[0126] Understandably, the performance index set refers to vehicle performance related to the quality of carbon deposits in the fuel tank, such as power output, acceleration performance, fuel consumption per unit mileage, acceleration time, maximum power, etc. The standard performance value set refers to the numerical set of various performance indicators for a vehicle fuel tank free of carbon deposits. Since there is a corresponding correlation between the quality of carbon deposits in the fuel tank and various performance indicators, once the performance test value set of the fuel tank to be cleaned is determined, the carbon deposit quality of the fuel tank to be cleaned can be evaluated based on the difference in each performance test value, and finally, the average value is taken to obtain the initial carbon deposit quality.

[0127] S3. Receive the carbon deposit cleaning mode input by the user, and extract the carbon deposit cleaning mode formula from the pre-built carbon deposit cleaning mode formula group according to the carbon deposit cleaning mode.

[0128] Understandably, the carbon deposit cleaning modes can be divided into fast cleaning mode and gentle cleaning mode. The fast cleaning mode refers to a carbon deposit cleaning mode measured by the speed of carbon deposit removal, while the gentle cleaning mode refers to a carbon deposit cleaning mode measured by the gentleness of carbon deposit removal. Since an excessively fast carbon deposit cleaning mode may cause some corrosion to the fuel tank and fuel lines, it is necessary to appropriately reduce the cleaning speed and increase the gentleness of carbon deposit removal to protect the fuel tank and fuel lines. The carbon deposit cleaning mode formula group refers to the combination of carbon deposit cleaning mode formulas corresponding to different cleaning modes. The carbon deposit cleaning mode formula refers to the carbon deposit effect evaluation formula corresponding to different cleaning modes.

[0129] In detail, the carbon deposit cleaning mode formula set includes: a carbon deposit cleaning speed formula and a carbon deposit cleaning gentleness formula, as shown below:

[0130]

[0131] Where s represents the carbon deposit cleaning rate within the carbon deposit cleaning time t, t represents the carbon deposit cleaning time, c0 represents the initial carbon deposit mass, and c t The remaining carbon deposit mass is represented by r, the carbon deposit cleaning flexibility is represented by m, the number of curve sampling points is represented by i, and the number of curve sampling points is represented by k. i This represents the slope of the i-th curve sampling point. Let α represent the average slope of m curve sampling points, α represent the slope exponent, and β represent the velocity exponent.

[0132] Understandably, the term "carbon deposit cleaning gentleness" refers to the gentleness of the carbon deposit cleaning process, which is assessed here based on the rate of change in the carbon deposit cleaning speed. Generally speaking, the faster the carbon deposit cleaning speed, the lower the carbon deposit cleaning gentleness.

[0133] S4. Obtain an initial time-carbon deposit curve set based on the initial carbon deposit quality and multiple sets of time-carbon deposit curve sets. Identify the target time-carbon deposit curve in the initial time-carbon deposit curve set according to the carbon deposit cleaning mode formula and the preset unit test duration.

[0134] Understandably, the initial time-carbon deposit curve set refers to the set of real-time carbon deposit quality prediction curves of the oil tank to be cleaned at various test temperatures, calculated based on the multiple sets of time-carbon deposit curves and the initial carbon deposit quality. The unit test duration refers to the periodic duration used to identify the target time-carbon deposit curve, and the unit test duration can be 10 minutes.

[0135] In this embodiment of the invention, obtaining the initial time-carbon deposition curve set based on the initial carbon deposition quality and multiple sets of time-carbon deposition curve sets includes:

[0136] Based on the initial carbon deposit quality, adjacent test carbon deposit quality pairs are extracted from the test carbon deposit quality sequence, wherein the adjacent test carbon deposit quality pairs include: the first test carbon deposit quality and the second test carbon deposit quality;

[0137] Based on the initial carbon deposit quality, the first test carbon deposit quality, and the second test carbon deposit quality, the carbon deposit quality difference ratio is calculated using a pre-constructed carbon deposit difference ratio formula, wherein the carbon deposit difference ratio formula is as follows:

[0138]

[0139] Where γ represents the ratio of carbon deposit mass difference, c 1 Indicates the carbon deposit quality in the first test, c 2 This indicates the carbon deposit quality in the second test; || represents the absolute value sign.

[0140] Based on the adjacent test carbon deposition quality pairs, extract the first time-carbon deposition curve set and the second time-carbon deposition curve set from the multiple sets of time-carbon deposition curve sets;

[0141] Based on the test temperature, extract the same temperature time-carbon deposition curve pairs from the first time-carbon deposition curve set and the second time-carbon deposition curve set;

[0142] Based on the carbon deposit mass difference ratio and the measurement unit duration, the time-carbon deposit point set corresponding to the test temperature is calculated using the same temperature time-carbon deposit curve.

[0143] The initial time-carbon deposition curve corresponding to the initial carbon deposition mass is fitted based on the time-carbon deposition point set;

[0144] By summarizing the initial time-carbon deposition curves corresponding to each test temperature, a set of initial time-carbon deposition curves is obtained.

[0145] Explained, the adjacent test carbon deposit mass pair refers to the test carbon deposit mass in the test carbon deposit mass sequence that is closest to the initial carbon deposit mass. For example, when the initial carbon deposit mass is 208g, and the test carbon deposit mass sequence is 100g, 200g, 300g, 400g, and 500g, the adjacent test carbon deposit mass pair is 200g and 300g. The first test carbon deposit mass and the second test carbon deposit mass can be 200g and 300g respectively. The first time-carbon deposit curve set and the second time-carbon deposit curve set refer to the time-carbon deposit curve sets that can be for test carbon deposit masses of 200g and 300g respectively. The same-temperature time-carbon deposit curve pair refers to two time-carbon deposit curves with the same test temperature in the first time-carbon deposit curve set and the second time-carbon deposit curve set.

[0146] Furthermore, the process of calculating the time-carbon deposition point set corresponding to the test temperature using the same-temperature time-carbon deposition curve based on the carbon deposition mass difference ratio and the measurement unit duration refers to: calculating the time-carbon deposition point set based on the carbon deposition mass difference ratio and the measurement unit duration, combined with the same-temperature time-carbon deposition curve. For example, when the carbon deposition mass difference ratio is 1:2 and the measurement unit duration is 1 minute, then the real-time carbon deposition mass at 1 minute on the first time-carbon deposition curve is 200. When the real-time carbon deposit mass at 1 minute on the second time-carbon deposition curve is 230g; the real-time carbon deposit mass at 2 minutes on the first time-carbon deposition curve is 190g; the real-time carbon deposit mass at 2 minutes on the second time-carbon deposition curve is 210g; the real-time carbon deposit mass at 3 minutes on the first time-carbon deposition curve is 170g; and the real-time carbon deposit mass at 3 minutes on the second time-carbon deposition curve is 200g, the coordinates of the first point in the time-carbon deposition point set are: And so on. Because there are multiple test temperatures, there are multiple initial time-carbon deposition curves.

[0147] In this embodiment of the invention, the step of identifying the target time-carbon deposit curve in the initial time-carbon deposit curve set according to the carbon deposit cleaning mode formula and the preset unit test duration includes:

[0148] The initial time-carbon deposition curves are extracted sequentially from the initial time-carbon deposition curve set, and the initial time-carbon deposition curve segment is extracted from the initial time-carbon deposition curve according to the unit test duration.

[0149] Determine whether the carbon deposit cleaning mode formula is a carbon deposit cleaning speed formula;

[0150] If the carbon deposit cleaning mode formula is a carbon deposit cleaning speed formula, then the unit test duration is used as the carbon deposit cleaning duration. The initial carbon deposit mass and the remaining carbon deposit mass are extracted from the initial time-carbon deposit curve segment. Based on the carbon deposit cleaning duration, the initial carbon deposit mass and the remaining carbon deposit mass, the carbon deposit cleaning speed is calculated using the carbon deposit cleaning mode formula to obtain the carbon deposit cleaning speed set.

[0151] Extract the maximum carbon deposit cleaning speed from the set of carbon deposit cleaning speeds, and identify the target time-carbon deposit curve corresponding to the maximum carbon deposit cleaning speed;

[0152] If the carbon deposit cleaning mode formula is not the carbon deposit cleaning speed formula, then obtain the number of unit test sampling points and use the number of unit test sampling points as the number of curve sampling points.

[0153] Based on the number of curve sampling points, a set of curve sampling points is set in the initial time-carbon deposition curve segment, and the slope of each curve sampling point in the set of curve sampling points is obtained to obtain a sequence of curve sampling point slopes.

[0154] Obtain the carbon cleaning speed of the initial time-carbon deposition curve segment, and calculate the carbon cleaning flexibility using the carbon cleaning mode formula based on the slope sequence of the curve sampling points, the number of curve sampling points, and the carbon cleaning speed to obtain the carbon cleaning flexibility set.

[0155] Extract the maximum carbon deposit cleaning flexibility from the set of carbon deposit cleaning flexibility, and identify the target time-carbon deposit curve corresponding to the maximum carbon deposit cleaning flexibility.

[0156] Understandably, the initial time-carbon deposit curve segment refers to the curve segment within the initial time-carbon deposit curve from the cleaning period of 0 to the unit test duration. The target time-carbon deposit curve refers to the curve in the initial time-carbon deposit curve set that best matches the carbon deposit cleaning mode within the unit test duration.

[0157] Furthermore, the number of unit test sampling points refers to the number of curve sampling points extracted within the initial time-carbon deposition curve segment. For example, when the number of unit test sampling points is 10 and the unit test duration is 10 minutes, the time axis coordinates of the curve sampling points are 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, and 10 minutes, respectively. The slope can represent the carbon deposition cleaning rate at that point.

[0158] S5. Extract the carbon cleaning cutoff point from the target time-carbon deposit curve according to the carbon cleaning mode formula, and identify the cutoff cleaning time and the cutoff carbon deposit quality corresponding to the carbon cleaning cutoff point.

[0159] Understandably, the carbon buildup cleaning cutoff point refers to the coordinate point corresponding to the maximum cleaning duration where the target time-carbon buildup curve best matches the carbon buildup cleaning mode. For example, within the unit test duration, the target time-carbon buildup curve best matches the carbon buildup cleaning mode. However, as the cleaning duration increases, the target time-carbon buildup curve may no longer be the time-carbon buildup curve that best matches the carbon buildup cleaning mode. The cleaning duration corresponding to the carbon buildup cleaning cutoff point is the cleaning duration where the target time-carbon buildup curve no longer best matches the carbon buildup cleaning mode. Therefore, it is necessary to identify the carbon buildup cleaning cutoff point and reselect the most suitable time-carbon buildup curve. For example, the target time-carbon buildup curve is the third time-carbon buildup curve in the initial time-carbon buildup curve set. The unit test duration is 10 minutes. When the cleaning duration reaches 15 minutes, the fifth time-carbon buildup curve is the curve that best matches the carbon buildup cleaning mode. At this time, the coordinate point corresponding to 15 minutes on the third time-carbon buildup curve is the carbon buildup cleaning cutoff point. The "cleaning cutoff time" refers to the cleaning duration corresponding to the carbon deposit cleaning cutoff point, and the "carbon deposit cutoff mass" refers to the carbon deposit mass of the oil tank to be cleaned at the "cleaning cutoff time".

[0160] In this embodiment of the invention, extracting the carbon deposit cleaning cutoff point from the target time-carbon deposit curve according to the carbon deposit cleaning mode formula includes:

[0161] Identify the initial cleaning cutoff point of the initial time-carbon buildup curve segment;

[0162] Based on the preset sampling interval duration and the carbon buildup cleaning duration at the initial cleaning cutoff point, the extended duration is calculated using a pre-constructed extended duration formula, wherein the extended duration formula is as follows:

[0163] t'=t+Δt

[0164] Where t' represents the extension duration and Δt represents the sampling interval duration;

[0165] Based on the extended duration, extract the extended time-carbon deposition curve segment set from the initial time-carbon deposition curve set;

[0166] Determine whether the carbon deposit cleaning mode formula is a carbon deposit cleaning speed formula;

[0167] If the carbon deposit cleaning mode formula is a carbon deposit cleaning speed formula, then the extended cleaning speed of each extended time-carbon deposit curve segment in the extended time-carbon deposit curve segment set is calculated using the carbon deposit cleaning mode formula to obtain the extended cleaning speed set.

[0168] Extract the maximum extended cleaning speed from the set of extended cleaning speeds, and identify the optimal time-carbon deposition curve segment corresponding to the maximum extended cleaning speed.

[0169] If the carbon deposit cleaning mode formula is not the carbon deposit cleaning speed formula, then the extended cleaning flexibility of each extended time-carbon deposit curve segment in the extended time-carbon deposit curve segment set is calculated using the carbon deposit cleaning mode formula to obtain the extended cleaning flexibility set.

[0170] Extract the maximum extended cleaning flexibility from the extended cleaning flexibility set, and identify the optimal time-carbon deposition curve segment corresponding to the maximum extended cleaning flexibility.

[0171] Identify the optimal cleaning cutoff point for the optimal time-carbon buildup curve segment;

[0172] Determine whether the optimal time-carbon deposition curve segment belongs to the target time-carbon deposition curve;

[0173] If the optimal time-carbon deposition curve segment belongs to the target time-carbon deposition curve, then the carbon deposition cleaning time and the initial cleaning cutoff point are updated using the extended duration and the optimal cleaning cutoff point, respectively, and the above steps of calculating the extended duration using the pre-constructed extended duration formula based on the preset sampling interval duration and the carbon deposition cleaning time are returned.

[0174] If the optimal time-carbon deposit curve segment does not belong to the target time-carbon deposit curve, then the initial cleaning cutoff point is taken as the carbon deposit cleaning cutoff point.

[0175] Understandably, the initial cleaning cutoff point refers to the end point of the initial time-carbon deposit curve segment, the sampling interval duration refers to the sampling interval duration for evaluating the mode fitness of the target time-carbon deposit curve, and the mode fitness refers to the degree to which the target time-carbon deposit curve conforms to the carbon deposit cleaning mode. The extended time-carbon deposit curve segment set refers to the set of multiple time-carbon deposit curve segments extracted from the initial time-carbon deposit curve set according to the extended duration. The optimal time-carbon deposit curve segment refers to the extended time-carbon deposit curve segment in the initial time-carbon deposit curve set that best conforms to the carbon deposit cleaning mode at the extended duration.

[0176] S6. Determine whether the cutoff carbon deposit quality is less than a preset carbon deposit quality threshold.

[0177] Understandably, the carbon deposit quality threshold refers to the maximum carbon deposit quality that meets the preset carbon deposit cleaning standard, which can be 100g.

[0178] If the cutoff carbon deposit quality is not less than the carbon deposit quality threshold, then execute S7 to update the initial carbon deposit quality using the cutoff carbon deposit quality.

[0179] Furthermore, when the cutoff carbon deposit quality is not less than the carbon deposit quality threshold, the initial carbon deposit quality should be updated using the cutoff carbon deposit quality, and the next cutoff carbon deposit quality should be re-identified.

[0180] Return to the steps outlined above for obtaining the initial time-carbon deposition curve set based on the initial carbon deposition quality and multiple sets of time-carbon deposition curve sets.

[0181] If the cutoff carbon deposit quality is less than the carbon deposit quality threshold, then execute S8, summarize all carbon deposit cleaning cutoff points to obtain a set of carbon deposit cleaning cutoff points, sort the set of carbon deposit cleaning cutoff points to obtain a sequence of carbon deposit cleaning cutoff points.

[0182] Understandably, when the carbon deposit mass at the cutoff point is less than the carbon deposit mass threshold, it indicates that the fuel tank to be cleaned has been cleaned. Therefore, all carbon deposit cleaning cutoff points can be summarized, and then sorted according to the cleaning time to obtain the carbon deposit cleaning cutoff point sequence.

[0183] In this embodiment of the invention, sorting the set of carbon deposit cleaning cutoff points to obtain a carbon deposit cleaning cutoff point sequence includes:

[0184] Extract the carbon deposit cleaning cutoff points sequentially from the set of carbon deposit cleaning cutoff points, identify the cutoff time of the carbon deposit cleaning cutoff points, and obtain the cutoff time set;

[0185] Sort the set of deadlines to obtain a deadline time sequence;

[0186] Identify the cutoff time number of the carbon deposit cleaning cutoff point in the cutoff time sequence;

[0187] The carbon deposit cleaning cutoff points are sorted according to the cutoff time number to obtain a carbon deposit cleaning cutoff point sequence.

[0188] For example, the carbon deposit cleaning cutoff point sequence can be (15min, 480g), (21min, 450g), (28min, 380g), (35min, 280g), (45min, 200g).

[0189] S9. Identify the carbon deposit cleaning temperature sequence corresponding to the carbon deposit cleaning cutoff point sequence, and perform temperature-controlled cleaning of the oil tank and oil circuit cleaning fluid according to the carbon deposit cleaning temperature sequence.

[0190] Understandably, the carbon deposit cleaning temperature sequence refers to the sequence composed of the test temperature and cleaning duration (cumulative) corresponding to each carbon deposit cleaning cutoff point in the carbon deposit cleaning cutoff point sequence.

[0191] In this embodiment of the invention, identifying the carbon deposit cleaning temperature timing sequence corresponding to the carbon deposit cleaning cutoff point sequence includes:

[0192] Extract the carbon deposit cleaning cutoff points sequentially from the carbon deposit cleaning cutoff point sequence, and identify the cutoff temperature and cutoff time corresponding to the carbon deposit cleaning cutoff point.

[0193] Construct a cutoff temperature-time based on the cutoff temperature and cutoff time;

[0194] The cutoff temperature times are sorted according to the carbon deposit cleaning cutoff point sequence to obtain the carbon deposit cleaning temperature time series.

[0195] For example, when the carbon deposit cleaning cutoff point sequence is (15min, 480g), (21min, 450g), (28min, 380g), (35min, 280g), (45min, 200g), and the corresponding test temperatures are 30℃, 40℃, 45℃, 35℃ and 40℃ respectively, the carbon deposit cleaning temperature sequence is (15min, 30℃), (21min, 40℃), (28min, 45℃), (35min, 35℃), (45min, 40℃).

[0196] In this embodiment of the invention, the step of performing temperature-controlled cleaning of the fuel tank and fuel system according to the carbon deposit cleaning temperature sequence includes:

[0197] Identify the termination cleaning time in the carbon deposit cleaning temperature sequence;

[0198] The cutoff temperature time is extracted sequentially from the carbon deposit cleaning temperature sequence.

[0199] The oil tank to be cleaned is subjected to constant temperature cleaning according to the cutoff temperature time, and the current cleaning time is monitored.

[0200] Determine whether the current cleaning time is equal to the cutoff time in the cutoff temperature time;

[0201] If the current cleaning time is not equal to the cutoff time in the cutoff temperature time, then return to the above steps of performing constant temperature cleaning on the oil tank to be cleaned according to the cutoff temperature time;

[0202] If the current cleaning time is equal to the cutoff time in the cutoff temperature time, then determine whether the current cleaning time is equal to the termination cleaning time;

[0203] If the current cleaning time is not equal to the termination cleaning time, then return to the steps described above of sequentially extracting the cutoff temperature time in the carbon deposit cleaning temperature sequence;

[0204] If the current cleaning time is equal to the termination cleaning time, then the temperature-controlled cleaning of the oil tank and oil circuit is completed.

[0205] Understandably, the termination cleaning time refers to the maximum cleaning duration in the carbon deposit cleaning temperature sequence. When the carbon deposit cleaning temperature sequence is (15min, 30℃), (21min, 40℃), (28min, 45℃), (35min, 35℃), (45min, 40℃), it indicates that the oil tank to be cleaned needs to be cleaned in the following order: using a constant temperature cleaning solution at 30℃ for 15min, using a constant temperature cleaning solution at 40℃ for 21min, using a constant temperature cleaning solution at 45℃ for 28min, using a constant temperature cleaning solution at 35℃ for 35min, and using a constant temperature cleaning solution at 40℃ for 45min.

[0206] Compared to the problems described in the background art, the embodiments of the present invention require temperature-controlled cleaning tests on fuel tanks with different carbon deposit qualities and different test temperatures. Therefore, it is necessary to first obtain a batch test fuel tank set, and then sequentially extract batch test fuel tanks from the batch test fuel tank set. This allows for temperature-controlled cleaning tests on the batch test fuel tanks according to a preset test temperature set, resulting in multiple sets of time-carbon deposit curves corresponding to each batch test fuel tank. At this point, a qualitative environmental test of the fuel tank to be cleaned is required to obtain the initial carbon deposit quality of the fuel tank to be cleaned. Since there are multiple carbon deposit cleaning modes, it is necessary to receive user... The input carbon deposit cleaning mode is used, and a carbon deposit cleaning mode formula is extracted from a pre-constructed set of carbon deposit cleaning mode formulas. Since the carbon deposit cleaning mode formula is determined by the initial carbon deposit quality, an initial time-carbon deposit curve set is first obtained based on the initial carbon deposit quality and multiple sets of time-carbon deposit curve sets. Then, a target time-carbon deposit curve is identified from the initial time-carbon deposit curve set based on the carbon deposit cleaning mode formula and a preset unit test duration. Since the target time-carbon deposit curve only best matches the carbon deposit cleaning mode within a unit test duration, it is necessary to further refine the calculation based on the input carbon deposit cleaning mode formula. The carbon buildup cleaning mode formula extracts the carbon buildup cleaning cutoff point from the target time-carbon buildup curve, then identifies the cutoff cleaning time and the cutoff carbon buildup quality corresponding to the cutoff point. To determine whether cleaning is complete, it is necessary to check whether the cutoff carbon buildup quality is less than a preset carbon buildup quality threshold. If the cutoff carbon buildup quality is not less than the carbon buildup quality threshold, the initial carbon buildup quality needs to be updated using the cutoff carbon buildup quality, and the initial time-carbon buildup curve set and carbon buildup cleaning cutoff point need to be re-acquired. If the cutoff carbon buildup quality is less than the carbon buildup quality threshold, it indicates that carbon buildup cleaning has been completed, and at this time... By summarizing all carbon deposit cleaning cutoff points, a set of carbon deposit cleaning cutoff points is obtained. This set is then sorted to obtain a sequence of carbon deposit cleaning cutoff points. At this point, it is only necessary to identify the carbon deposit cleaning temperature sequence corresponding to the carbon deposit cleaning cutoff point sequence, and perform temperature-controlled cleaning of the fuel tank and fuel system according to this sequence. Therefore, the main purpose of the fuel tank and fuel system temperature-controlled cleaning method, device, electronic equipment, and computer-readable storage medium proposed in this invention, based on qualitative analysis of the fuel tank environment, is to solve the problems of poor selectivity of cleaning modes and low cleaning efficiency in current fuel tank and fuel system cleaning methods.
