[0055] In order to make the purpose, technical solutions and advantages of this application clearer, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0056] The method for determining the use performance of a cleaning agent provided in the embodiments of this application can be applied to, for example Figure 1In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or can be placed on the cloud or other network servers. For example, the server 104 determines the test environment corresponding to the test piece of the target aircraft according to the actual service environment of the target aircraft; obtains the key indicators of the test piece; among them, the test piece is the test piece cleaned with the target cleaning agent under the test environment; according to the key indicators, determines the use performance of the target cleaning agent. According to the key indicators, determines the use performance of the target cleaning agent. Further, after the server 104 determines the use performance of the target cleaning agent, it can send the determined performance-related data to the terminal 102 for the user to view. Among them, the target aircraft can be devices such as airplanes and drones; the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0057] During the flight and parking of an aircraft (such as an airplane), pollutants such as salt spray, dust, sand, and oil stains will inevitably deposit on the surface and components. These pollutants will not only affect the appearance of the airplane, but may also endanger the flight safety of the airplane. Therefore, it is necessary to use a cleaning agent to clean these pollutants in a timely manner. Currently, the evaluation of the cleaning effect of aircraft cleaning agents mainly relies on the development standards of cleaning agents, and correspondingly carries out test items such as the cleaning efficiency, full immersion corrosion, crevice corrosion, and hydrogen embrittlement test of specific material test pieces.

[0058] Among them, the test environment includes natural environment and laboratory simulation environment. Conducting tests in the natural environment is to place the test sample in the natural environment according to the expected use requirements, assess the impact of the natural environment on its function and (or) performance, and evaluate its environmental adaptability. The natural environment mainly includes atmospheric environment, water environment, soil environment, space environment, etc. Laboratory simulation environment tests are simulation tests carried out in the laboratory according to the specified environmental conditions and load conditions to simulate the natural environmental conditions. The main environmental types in the laboratory include climate environment, mechanical environment, chemical environment, electromagnetic environment, etc. In traditional technologies, when testing the use performance of a cleaning agent, the cleaning agent is used to clean the test piece and place it in the laboratory simulation environment, and various key indicators of the test piece are collected to indirectly determine the use performance of the cleaning agent. However, there is still a certain error between the use performance of the cleaning agent detected in the above-mentioned test items in the laboratory and the actual application effect of the cleaning agent. Therefore, it is urgent to improve.

[0059] In one embodiment, as Figure 2 shown, a method for determining the use performance of a cleaning agent is provided. Taking the server 104 in Figure 1 as an example, the method includes the following steps:

[0060] S201. Determine the test environment for cleaning the test piece with the target cleaning agent according to the actual service environment of the target aircraft.

[0061] Among them, the test piece corresponds to the target aircraft. The target aircraft is the object to which the cleaning agent is to be applied; the actual service environment of the target aircraft refers to the flight environment and parking environment during the service of the aircraft. Exemplarily, the actual service environment may include various complex meteorological conditions such as cold, cold and warm, warm and temperate, sub-humid and hot, humid and hot, dry and hot, ice and snow, monsoon, heavy rain, etc., and also includes extreme climate conditions such as severe cold, ocean, plateau, desert, etc. Specifically, the server 104 determines the test environment corresponding to the actual service environment, and then the test piece conducts tests in this test environment. Exemplarily, if the actual service environment of the aircraft is the ocean environment among the above, the test environment corresponding to the test piece is also the ocean environment. In one implementable manner, the test pieces of the target aircraft can be various components that need to be cleaned of the target aircraft; in another implementable manner, the test piece can also be prepared according to the materials of the parts to be cleaned of the target aircraft. Specifically, various types of test pieces of the target aircraft may include: metal test pieces, coated test pieces, composite material coated test pieces, plexiglass test pieces, insulated wire test pieces, rubber material test pieces, sealant test pieces, etc.

[0062] S202. Obtain the key indicators of the test piece.

[0063] Among them, the test piece is the test piece cleaned with the target cleaning agent in the test environment.

[0064] Among them, the target cleaning agent can be a water-based cleaning agent, a solvent-based cleaning agent, a special cleaning agent, etc. Among them, the use performance of the cleaning agent can be characterized by key indicators of physical and chemical properties and key indicators of use performance. The key indicators of physical and chemical properties describe the physical properties and chemical properties of the cleaning agent such as its properties, solubility, volatility, stability, acidity, toxicity, etc.; the key indicators of use performance include the cleaning ability of the cleaning agent for various types of oil stains on the aircraft and the key indicators of the compatibility between the cleaning agent and the aircraft materials. Specifically, the key indicators of use performance are reflected by the results of acting on the object to be cleaned and are closely related to the key indicators of physical and chemical properties. For test pieces of different materials (different types), the corresponding key indicators are also different.

[0065] The following explains the key indicators corresponding to the above various types of test pieces;

[0066] (1) Key indicators of metal materials: Solvent-based cleaning agents are commonly used to clean aircraft metal components, dissolving and removing mixtures of lubricating oil, grease, and other dirt on the components. The key indicators of the impact on metal materials are the pass / fail criteria for tests such as full immersion corrosion, intergranular corrosion, stress corrosion, and hydrogen embrittlement of various metals and their alloys used in aircraft, including aluminum, titanium, steel, magnesium, copper, etc. After completing the full immersion corrosion test of the cleaning agent on aircraft metal materials according to the specified test method standard, it is required that the metal specimens used for the test should have no visible corrosion and the weight loss should not exceed the permitted specified value; after the intergranular corrosion test, it is required that the corrosion degree of the specimens should not exceed that of the reference reagent water, or there should be only extremely slight corrosion; after the stress corrosion test, it is required that no cracking should occur in the specimens; after the hydrogen embrittlement test, if all specimens do not break, the key indicators of the cleaning agent are considered qualified.

[0067] (2) Key indicators of non-metal materials: When cleaning the aircraft structure surface, metal components, electronic equipment, etc., the cleaning agent will come into contact with non-metal materials such as coatings, rubber, plastics, sealants, and insulated wires. Therefore, it is necessary to conduct tests on the impact of the cleaning agent on these non-metal materials. After the specified standard tests, the cleaning agent should not cause streaks, fading, blistering, or discoloration of the coatings of aircraft and components, and the change in coating hardness before and after cleaning should not exceed the specified value; the cracking of insulated wires should not be less than the impact of the reference reagent water on the wires, and no breakdown or leakage should occur in the dielectric test; the change in hardness of the sealant before and after the test should not exceed the specified value; there should be no cracking or swelling of elastomers such as rubber, and the change in hardness before and after the test should not exceed the specified value; no silver streaks, cracking, or strength loss should occur in plastics.

[0068] Specifically, the test specimens of each material and the corresponding key indicators of each test specimen can refer to Table 1 below:

[0069] Table 1

[0070]

[0071] Optionally, to improve the test accuracy, the number of test specimens of each type in this embodiment can be set to multiple, that is, a metal specimen group, a coating specimen group, a composite material coating specimen group, a plexiglass specimen group, an insulated wire specimen group, a rubber material specimen group, and a sealant specimen group are formed, etc. Correspondingly, when determining the key indicators of each test specimen, the average value of the key indicators of each specimen in the test specimen group can be used as the key indicator of this type of test specimen.

[0072] Exemplarily, if the above metal specimen group includes {Metal Specimen 1, Metal Specimen 2, Metal Specimen 3}, then the key index 1 of Metal Specimen 1, the key index 1 of Metal Specimen 2, and the key index 1 of Metal Specimen 3 are combined and the average value is determined, and this average value is determined as the key index 1 of this type of specimen to be tested. Among them, the number of specimens in each specimen group to be tested can be comprehensively determined according to factors such as the number of key indexes, whether the test is a destructive test, the test cycle, the detection timing, etc.

[0073] S203. Determine the use performance of the target cleaning agent according to the key index.

[0074] In one implementable manner, the number of target cleaning agents is one. When determining the use performance of the target cleaning agent: after the specimen to be tested is cleaned with the target cleaning agent in the test environment, the key index of the specimen to be tested obtained can be compared with the historical key index or the preset performance standard to determine the use performance of the target cleaning agent. Among them, the number of cleaning times can be at least once, and the cleaning step is independent of the step of obtaining the key index; when obtaining the key index, the corresponding index at the corresponding moment can be obtained according to the set time interval and the number of samplings. Specifically, when determining the use performance of the target cleaning agent, the key index of the specimen to be tested is compared with each index interval, and each index value interval corresponds to each performance level. If the key index of the specimen to be tested falls into which index interval, the use performance of the target cleaning agent is determined as the performance level corresponding to this index interval.

[0075] In another implementable manner, the number of target cleaning agents is at least two, and the types of each target cleaning agent are different. For example, target cleaning agent A, target cleaning agent B, etc. As shown in the above example, the key indexes corresponding to the two target cleaning agents are compared to determine the performance difference between the two target cleaning agents to obtain a cleaning agent with better performance. Specifically, when conducting the test, the specimens to be tested of each type (material) can be divided into two different test groups, and each test group corresponds to a target cleaning agent, as shown in Table 2 below:

[0076] Table 2

[0077]

[0078]

[0079] In the above method for determining the use performance of the cleaning agent, by determining the use performance of the target cleaning agent in the test environment that simulates the actual service environment of the target aircraft, the use effect of the target cleaning agent in the actual service environment can be more accurately simulated; further, according to the key index of the specimen to be tested, the cleaning effect of the cleaning agent can be accurately quantified.

[0080] In order to further improve the test accuracy, in one embodiment, each test specimen is prepared according to the corresponding preparation standard of each specimen material.

[0081] Among them, the metal specimen can be prepared according to the preparation standard of GB / T14165-2008 "General Requirements for Field Tests of Atmospheric Corrosion of Metals and Alloys". The size of the metal specimen is specified as 250mm×150mm or 150mm×75mm; according to relevant technical requirements, the edges of the metal specimen are sealed, and the sealing width is 3mm to 5mm. The reverse side of the specimen that needs to test the corrosion depth also needs to be painted.

[0082] The coated specimen is prepared according to the preparation standard of GB / T9276-1996 "Test Method for Natural Weathering of Coatings". The size of the coated specimen is specified as 250mm×150mm or 150mm×75mm; in order to prevent moisture and other impurities from entering the specimen from the side during the test, resulting in a failure mode that does not conform to the actual situation and affecting the evaluation result, the front and back sides and the periphery of the coated specimen need to be coated. If the periphery is not coated, it needs to be sealed, and the sealing width is generally 5mm.

[0083] For the prefabricated scratches of the coated specimen, according to the standard GB / T30786-2014 "Guide for Scratch Marking of Metal Plate Coatings for Corrosion Testing of Paints and Varnishes", cross scratches are prefabricated in the center of the specimen, and the distance from the edge of the scratch to the edge of the sample is greater than or equal to 20cm, and the scratch penetrates the coating system to the metal matrix; or it is prepared according to ASTM D1654 "Appearance Rating of Front-Scratched Specimens", and "cross" scratches with a length of 20mm longitudinally and 10mm transversely are prefabricated in the center of the specimen, and the scratch penetrates the coating system to the metal matrix. The prefabricated scratch method used in the same performance test should be consistent.

[0084] Among them, the size and preparation of specimens such as plexiglass are carried out according to the preparation standard of GJB5974-2007 "Specification for Aqueous Aircraft Exterior Cleaners".

[0085] In one embodiment, the cleaning modes corresponding to the test specimens of the same material may be different (for example, manual cleaning and automatic cleaning), and the actual service positions of the test specimens of the same material on the target aircraft may also be different (for example, the outer surface of the target aircraft and the natural environment under the shed of the target aircraft). Therefore, in order to enable the test to further simulate the actual use scenario, as Figure 3 shown, this embodiment provides an optional method for obtaining the key indicators of the test specimen, which may specifically include the following process:

[0086] S301, determine the cleaning mode and sub-test environment of the test specimen.

[0087] Among them, the sub-test environment is the natural environment under the shed or the outdoor natural environment in the test environment; the natural environment under the shed can be the environment under the test shed built in the test environment. Compared with the directly exposed outdoor natural environment, the light intensity of the environment under the shed is weaker. Among them, the cleaning modes include manual cleaning method and mechanical equipment cleaning method. In addition, according to the characteristics of the cleaning medium, it is also divided into wet cleaning method and dry cleaning method.

[0088] Specifically, each test piece to be tested corresponds to a unique number. When the server 104 obtains the number of any test piece to be tested, it is equivalent to obtaining the test piece to be tested. According to the preset comparison table, the cleaning mode and sub-test environment of the test piece to be tested are determined. Among them, the preset comparison table stores the cleaning modes and sub-test environments of each test piece to be tested. Then, the server 104 generates a cleaning task based on the corresponding cleaning mode and sub-test environment, and issues the cleaning task.

[0089] S302. Obtain the key indicators of the test piece to be tested according to the cleaning mode and sub-test environment.

[0090] Among them, the test piece to be tested is the test piece cleaned based on the target cleaning agent and cleaning mode in the sub-test environment.

[0091] Specifically, when obtaining the key performance indicators, for example, the mass change of the metal test piece can be determined according to GB16545-2015 "Corrosion of Metals and Alloys - Removal of Corrosion Products from Corroded Test Pieces"; the corrosion depth of the metal test piece can be determined according to GB / T18590-2001 "Corrosion of Metals and Alloys - Method for Pitting Corrosion Assessment".

[0092] Furthermore, the aging rating of the coated test piece can be determined according to GB / T1766-2008 "Rating Method for Coating Aging"; the color difference of the coated test piece can be determined according to GB / T11186-1989 "Measurement Method for Paint Film Color"; the gloss of the coated test piece can be determined according to GB / T9754-1988 "Determination of 20°, 60° and 85° Specular Gloss of Paints and Varnishes - Non-Metallic Pigment-Free Paints"; the hardness of the coated test piece can be determined according to GB / T1730-2007 "Paints and Varnishes - Pendulum Damping Test"; the thickness of the coated test piece can be determined according to GB / T4956-2003 "Measurement of Coating Thickness on Magnetic Substrates - Magnetic Method"; the adhesion of the coated test piece can be determined according to GB / T5210-2006 "Paints and Varnishes - Pull-Off Adhesion Test" or with reference to GB / T9286-1998 "Cross-Cut Test for Paints and Varnishes Film"; for the low-frequency impedance of the coated test piece, the amplitude of the input signal should be set to 20mv relative to the open-circuit potential, the frequency range should be set to 105~10-2HZ, and the corresponding key indicators should be determined.

[0093] Further, the test item of the plexiglass specimen is whether silver streaks appear on the surface after loading, which is determined according to ASTM F484. The key indicators of other types of specimens are determined according to the sensitive properties of the materials. For example, the electrical insulation performance of insulated wires can be determined according to GB / T 1408-2006 "Test Method for Electrical Strength of Solid Insulating Materials"; the tensile strength of rubber materials can be determined according to GB / T 528-1998 "Determination of Tensile Stress-Strain Properties of Vulcanized Rubber or Thermoplastic Rubber"; the hardness of sealants can be determined according to GB / T 531-1999 "Test Method for Indentation Hardness of Rubber Pocket Hardness Tester".

[0094] Specifically, after the cleaning task is completed, the server 104 obtains, from the corresponding test equipment, the key indicators of the test specimen to be tested when the test specimen to be tested is cleaned with the target cleaning agent in the corresponding cleaning mode and sub-test environment. In addition, the server 104 can configure corresponding weight values for each key indicator, and comprehensively determine the service performance of the target cleaning agent according to the key indicators of each test specimen to be tested and the weight values of each key indicator.

[0095] To determine the long-term cumulative effect of the target cleaning agent. In one embodiment, as Figure 4 shown, this embodiment provides an optional way to obtain the key indicators of the test specimen to be tested, that is, provides a way to refine S202. The specific implementation process may include:

[0096] S401, determine at least two test times.

[0097] Among them, the test time refers to the time when the key indicators of the test specimen to be tested are tested; each test time can be set by human experience or determined according to a preset calculation rule, and each target cleaning agent can correspond to different test times.

[0098] S402, obtain the stage key indicators of the test specimen to be tested at each test time.

[0099] Among them, if the test specimen to be tested is the above-mentioned test specimen group including multiple specimens, then based on the stage key indicators of each specimen in the test specimen group, determine the stage key indicators of the test specimen group.

[0100] Exemplarily, at any test time, when determining the cleaning effect of the corresponding target cleaning agent pair on the metal material according to the stage key indicators corresponding to each test time of the metal specimen group, refer to the following table - Table 3:

[0101] Table 3

[0102]

[0103] Specifically, the stage key indicator 1 at the test moment can be determined according to the average value of a1, b1, c1, and d1, the stage key indicator 2 at the test moment can be determined according to the average value of a2, b2, c2, and d2, and the stage key indicator 3 at the test moment can be determined according to the average value of a3, b3, c3, and d3.

[0104] Correspondingly, according to the key indicators, the usage performance of the target cleaning agent is determined, including: according to the stage key indicators of each stage, the usage performance of the target cleaning agent is determined.

[0105] As in the above example, according to the stage key indicators of each test specimen group, the usage performance of the target cleaning agent is determined. Exemplarily, the metal specimen group corresponds to the cleaning effect of the target cleaning agent on the metal material, the coated specimen group corresponds to the cleaning effect of the target cleaning agent on the coating, the plexiglass specimen group corresponds to the cleaning effect of the target cleaning agent on the plexiglass, and the rubber material specimen group corresponds to the cleaning effect of the target cleaning agent on the rubber; according to the cleaning effects of the target cleaning agent on different materials, the cleaning effect of the target cleaning agent is comprehensively determined.

[0106] Specifically, as in the example of S201, if the target cleaning agent includes target cleaning agent A and target cleaning agent B, the key indicators corresponding to the two target cleaning agents are compared to determine the performance difference between the two target cleaning agents, so as to obtain the cleaning agent with better performance, including:

[0107] Use target cleaning agent A to clean each test group A in Table 2, and use target cleaning agent B to clean each test group B in Table 2; for the convenience of description, in this embodiment, the test moment of target cleaning agent A is the same as that of target cleaning agent B. Taking the coated specimen in the test specimen as an example, the stage key indicators obtained are as follows in Table 4:

[0108] Table 4

[0109]

[0110] Exemplarily, 1 month is the first test moment, 3 months is the second test moment, and 6 months is the third test moment. In Table 4, which target cleaning agent is filled in each key indicator means that the usage performance of this cleaning agent is better than that of the other cleaning agent.

[0111] Exemplarily, when measuring the key index of the loss of gloss rate, at the 1st month, the index of the target cleaning agent A is better than that of the target cleaning agent B; at the 3rd month, the index of the target cleaning agent A is better than that of the target cleaning agent B; at the 6th month, the index of the target cleaning agent A is better than that of the target cleaning agent B. Based on the key indexes at each stage, the target cleaning agent with better performance for the coated specimen can be determined. For example, the target cleaning agent A in Table 4 has better cleaning performance for the coated specimen.

[0112] Furthermore, determine the target cleaning agents with better performance corresponding to each different type of specimen to be tested, so as to comprehensively determine the target cleaning agent corresponding to the target aircraft. In this embodiment, based on the key indexes at different test times, record the long-term cumulative effect of the target cleaning agent to improve the accuracy of the evaluation of the service performance of the target cleaning agent.

[0113] Since the service performance of each target cleaning agent is unknown, if the test times are all set manually, the unified test timing may not be applicable to different types of target cleaning agents and different test environments. Therefore, in one embodiment, at least two test times include at least one initial test time and at least one target test time; the target test time is later than the initial test time; as Figure 5 shown, this embodiment provides an optional way to determine at least two test times, that is, provides a way to refine S401. The specific implementation process may include:

[0114] S501, for each target test time, determine the test time interval according to the key indexes at each historical test time before this target test time.

[0115] Among them, the initial test time refers to the test time set manually, and the target test time refers to the test time deduced according to the initial test time with a preset calculation rule. Furthermore, each historical test time includes the initial test time before this target test time, or each historical test time includes the initial test time and the target test time before this target test time.

[0116] Exemplarily, if the initial test time includes the first initial test time and the second initial test time, then the historical test times of the first target test time include the initial test times before this target test time (that is, the first initial test time and the second initial test time); the historical test times of the second target test time include the initial test times and the target test time before this target test time (that is, the first initial test time, the second initial test time, and the first target test time).

[0117] Among them, the test time interval refers to the test time interval between the target test moment and the previous historical test moment. In one implementable manner, the test time interval can be determined according to the stage key indicators corresponding to each historical test moment before the target test moment. In another implementable manner, some of the stage key indicators corresponding to each historical test moment before the target test moment can be selected to determine the test time interval.

[0118] S502. Determine the target test moment according to the test time interval and the previous historical test moment of the target test moment.

[0119] Specifically, for any target test moment, the historical test moments of the target test moment are, from far to near, {initial test moment 1, initial test moment 2, target test moment 1, target test moment 2} in sequence. After determining the test time interval, the current target test moment is determined according to the previous historical test moment (target test moment 2) of the current target test moment and the test time interval.

[0120] In this embodiment, the purpose of setting the target test moment is to determine the test time interval according to the change of the stage key indicators, so as to accurately collect at the moment when the stage key indicators change significantly, and further accurately measure the change of the use performance of the target cleaning agent.

[0121] In one embodiment, as Figure 6 shown, this embodiment provides an optional method for determining the test time interval according to the stage key indicators corresponding to each historical test moment before the target test moment, which may specifically include the following steps:

[0122] S601. Determine the index change rate according to the stage key indicators corresponding to a preset number of historical test moments before the target test moment.

[0123] Among them, the purpose of selecting the stage key indicators corresponding to a preset number of historical test moments is to make the current test time interval only related to the stage key indicators corresponding to adjacent historical test moments, and enhance the correlation between data.

[0124] In one implementable manner, the stage key indicators corresponding to a preset number of historical test moments can be the stage key indicators corresponding to the first initial test moment and the stage key indicators corresponding to the two target test moments before the target test moment.

[0125] Specifically, to determine the index change rate, the following formula (1) is used:

[0126]

[0127] Among them, x0 is the key stage index corresponding to the first initial test moment; x k is the key stage index corresponding to the previous historical test moment of the target test moment; x k-1 is the key stage index corresponding to the first two historical test moments before the target test moment; δ is the index change rate; k represents the k-th test moment.

[0128] Corresponding to Table 3, taking any specimen in the metal specimen group, i.e., metal specimen a as an example, the calculation process of the index change rate is as shown in Table - Table 5:

[0129] Table 5

[0130]

[0131]

[0132] Among them, the index change rate of metal specimen a includes the change rates of each key stage index (i.e., change rate Δa1, change rate Δa2, and change rate Δa3); similarly, the index change rate of metal specimen b includes the change rates of each key stage index (i.e., change rate Δb1, change rate Δb2, and change rate Δb3).

[0133] In an implementable manner, as shown in Table 3, for the same specimen group, based on each key index, the index change rate for this specimen group is comprehensively determined, which may specifically include: according to each specimen (e.g., specimen a, specimen b, specimen c, and specimen d), comprehensively determine the change rate of key stage index 1 (which can be determined according to the average value of change rate Δa1, change rate Δb1, change rate Δc1, and change rate Δd1); comprehensively determine the change rate of key stage index 2 (which can be determined according to the average value of change rate Δa2, change rate Δb2, change rate Δc2, and change rate Δd2); comprehensively determine the change rate of key stage index 3 (which can be determined according to the average value of change rate Δa3, change rate Δb3, change rate Δc3, and change rate Δd3); further, based on the change rate of key stage index 1, the change rate of key stage index 2, and the change rate of key stage index 3 for this specimen group, determine the index change rate δ. Exemplarily, the average value taking method can be adopted.

[0134] In another implementable manner, the change rate of the indicators can also be comprehensively determined based on the respective key indicators of different test piece groups, specifically including: respectively determining the change rates of the key indicators at each stage corresponding to each test piece group, determining the comprehensive change rate according to the change rates of the key indicators at each stage, and the comprehensive change rate can be determined according to the average value of the change rates of the key indicators at each stage. At this time, the comprehensive change rate is δ in formula (1); by means of the comprehensive change rate, the same test time interval is corresponding to all the test pieces to be tested of the target aircraft, so that different test piece groups are tested at the same test frequency, and at the same time, each different test piece can be taken into account.

[0135] S602. Determine the test time interval according to the change rate of the indicators.

[0136] Among them, when determining the test time interval according to the change rate of the indicators, in one implementable manner, an initial test time interval can be set. When δ > 20%, the initial test time interval is reduced according to a preset ratio to determine the test time interval; when δ ≤ 20%, the initial test time interval is reduced according to a preset ratio to determine the test time interval.

[0137] In this embodiment, when the change range of the change rate of the indicators is large, the test time interval is shortened to accurately record the change of the key cleaning indicators; when the change range of the change rate of the indicators is large, the initial test time interval is tested to determine the test time interval to adapt to the slowly changing key indicators.

[0138] Exemplarily, on the basis of the above embodiments, this embodiment provides an optional example of a method for determining the use performance of a cleaning agent. As Figure 7 shown, the specific implementation process includes:

[0139] S701. Determine the test environment for cleaning the test pieces to be tested with the target cleaning agent according to the actual service environment of the target aircraft;

[0144] S704. Obtain the key indicators at each stage of the test pieces to be tested at each test time;

[0145] S705. Determine the use performance of the target cleaning agent according to the key indicators at each stage.

[0146] Among them, at least two test times include at least one initial test time and at least one target test time; the target test time is later than the initial test time; determining at least two test times includes: for each target test time, determining an index change rate according to the stage key indexes corresponding to a preset number of historical test times before the target test time; determining a test time interval according to the index change rate; and determining the target test time according to the test time interval and the previous historical test time of the target test time.
