That is, these functional entities can be implemented in software, in one or more hardware charging modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0050] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0051] To address the problems in the background art, embodiments of the present invention provide a salt spray test control method, system, device, and storage medium. By improving the stability of the concentration and pH value of the neutral salt spray chamber recovery liquid and adopting an appropriate ratio, the accuracy of salt spray test control is improved.

[0052] like Figure 1 As shown, Figure 1 A salt spray test control method provided in this embodiment of the invention includes the following steps:

[0053] S100, Obtain the spray volume required for the salt spray test, and determine the height and pressure of multiple spray towers set at the bottom of the salt spray chamber based on the spray volume;

[0054] S200, after heating the salt solution stored at the bottom of the salt spray chamber to a set temperature, a pressure-controlled spray tower is used to spray the salt solution into the interior of the salt spray chamber in the form of a spray to perform a salt spray test on the testing equipment; wherein, the bottom ends of the plurality of spray towers are connected to the salt solution;

[0055] It should be noted that in the embodiments provided by the present invention, the salt solution is heated to a specified experimental temperature (e.g., 35°C) by high temperature and high pressure, and the spray tower sprays the salt solution to corrode the materials of the test equipment.

[0056] The S300 controls multiple spray towers to stop spraying after the test duration is reached.

[0057] It should be noted that in the embodiments provided by the present invention, the height and pressure of the spray tower are determined based on the spray volume, and then the salt solution is sprayed to conduct salt spray tests on the test equipment. This can conduct salt spray tests on the test equipment with a stable spray volume, ensuring the consistency of the salt spray test environment and having high test accuracy.

[0058] In some improved embodiments, in S100, determining the height and pressure of the plurality of spray towers disposed at the bottom of the salt spray chamber based on the spray volume includes:

[0059] S110, Obtain the bottom area of ​​the salt spray chamber and the number of spray towers to determine the coverage area of ​​a single spray tower; wherein, multiple spray towers are evenly arranged at the bottom of the salt spray chamber;

[0060] S120, determine the spray volume of the spray tower per unit time based on the coverage area;

[0061] S130, determine the pressure of the spray from the spray tower based on the amount of spray per unit time;

[0062] S140, determine the coverage area of ​​the spray tower under different pressures, and then determine the height of the spray tower under the coverage area of ​​the single spray tower.

[0063] In some improved embodiments, in S200, the method further includes:

[0064] S201, within the test duration, determine the average sedimentation amount of the salt spray chamber; wherein, the average sedimentation amount characterizes the amount of salt solution volatilized per unit time;

[0065] S202, the replenishment rate of the salt solution is determined based on the average sedimentation amount, and the salt solution stored in the replenishment tank is controlled to be delivered to the salt spray box at the replenishment rate.

[0066] It should be noted that in the embodiments provided by the present invention, the replenishment box is used to store the salt solution and is connected to the salt spray chamber. When the test equipment is subjected to salt spray testing, by continuously replenishing the salt solution in the salt spray chamber, the consistency of the salt spray test environment can be ensured, and high test accuracy can be guaranteed.

[0067] It should be noted that after the salt spray chamber is heated (for example, when the temperature reaches 35°C), carbon dioxide is released inside the salt spray chamber, causing the salt solution to dilute. After a period of time, the concentration of the salt solution gradually decreases, especially after the spray is formed, which further exacerbates the dilution. Therefore, the concentration and pH value of the salt solution treated in this way cannot remain constant. Moreover, after multiple tests, the deviations in salt concentration and pH value cannot simultaneously meet the qualification requirements (for example, the concentration deviation within ±0.5% and the pH value deviation within ±0.5%).

[0068] In some improved embodiments, prior to S200, the method further includes:

[0069] S211, a salt spray test is conducted using multiple sets of prepared solutions configured with pre-set salt water concentrations and pH values. Each set of prepared solutions has a different sodium bicarbonate concentration, wherein the sodium bicarbonate concentration is the weight ratio of sodium bicarbonate to salt water.

[0070] It should be noted that in the embodiments provided by the present invention, the salt concentration and pH value are preset according to the requirements of the test standard. After the salt concentration and pH value are set, sodium bicarbonate in different weight ratios is added to prepare salt solutions with different sodium bicarbonate concentrations as preparation solutions.

[0071] S212, after the test is completed, collect multiple sets of solutions corresponding one-to-one with multiple sets of prepared solutions, and determine the amount of change in each set of prepared solutions and collected solutions; wherein, the amount of change includes the amount of change in concentration and the amount of change in pH value;

[0072] It should be noted that in the embodiments provided by the present invention, multiple sets of collection solutions are collected as samples after the test is completed, so as to determine the amount of concentration change and pH change.

[0073] S213, determine the functional relationship between sodium bicarbonate concentration and the change, and based on the functional relationship, determine the range of sodium bicarbonate concentration values ​​for the collected solution to meet the test standards.

[0074] S214, Prepare a salt solution based on the range of values ​​for the salt concentration, pH value, and sodium bicarbonate concentration.

[0075] It should be noted that in the embodiments provided by the present invention, by adding a set proportion of sodium bicarbonate to the salt solution, sodium bicarbonate plays a role in stabilizing the concentration. The salt solution prepared with sodium bicarbonate has a smaller concentration variation and can meet the deviation requirements of salt water concentration and pH value.

[0076] In some improved embodiments, in S212, the step of collecting multiple sets of solutions corresponding one-to-one with multiple sets of prepared solutions after the test is completed includes:

[0077] Sample solutions are collected through multiple funnels, which are evenly arranged at different positions at the bottom of the salt spray chamber.

[0078] The sample solutions collected from multiple funnels are mixed to obtain a collection solution, and the collection solution is then matched with the prepared solution before testing.

[0079] In some embodiments, the bottom of the salt spray chamber is provided with multiple funnels to ensure that the concentration of the sample solution in all positions within the salt spray chamber is qualified. The multiple funnels are evenly arranged at different positions on the bottom of the salt spray chamber. The spray in the salt spray chamber is recovered through the funnels, and the recovered spray is converted into a sample solution and introduced into a graduated cylinder. The concentration and pH value of the sample solution recovered in the graduated cylinder are measured to confirm whether the concentration and pH value of the salt solution have changed, and the amount of change.

[0080] In some improved embodiments, in S213, determining the functional relationship between the sodium bicarbonate concentration and the change, and determining the brine concentration and pH value of the collected solution within a range that meets the test standards based on the functional relationship, includes:

[0081] Linear regression was used to determine the first functional relationship between sodium bicarbonate concentration and concentration change, and the range of values ​​for salt concentration change under the test standard was determined. Based on the first functional relationship, the first range of values ​​for sodium bicarbonate concentration corresponding to the range of values ​​for concentration change was determined.

[0082] A second functional relationship between sodium bicarbonate concentration and pH change was determined by linear regression. The range of pH change under the test standard was determined. Based on the second functional relationship, a second range of sodium bicarbonate concentration corresponding to the range of pH change was determined.

[0083] The common interval between the first and second value ranges is taken as the value range of sodium bicarbonate concentration.

[0084] In some improved embodiments, the method further includes:

[0085] The test results are obtained by comparing the test items of the test equipment before and after the test.

[0086] The following are the relevant parameters recorded in the experiment;

[0087] Table 1: Parameter Recording Table of Solution Preparation Before and After Adding Sodium Bicarbonate

[0088]

[0089]

[0090] Table 2: Record of some parameters of the collected solution before and after the addition of sodium bicarbonate

[0091]

[0092] Table 3: Record of additional parameters of the collected solution before and after the addition of sodium bicarbonate

[0093]

[0094]

[0095] As can be seen from Tables 1, 2, and 3, adding sodium bicarbonate to the salt solution reduces the changes in concentration and pH value, thus ensuring that both the salt concentration and pH value meet the requirements of the testing standards. By further determining the functional relationship between sodium bicarbonate concentration and these changes, and based on this relationship, the salt concentration and pH value of the collected solution can be configured within the range of sodium bicarbonate concentration values ​​that meet the testing standards. This allows for the preparation of a highly stable salt solution, ensuring the consistency of the salt spray testing environment and guaranteeing high testing accuracy.

[0096] See Figure 2 This invention provides a salt spray test control system, the system comprising:

[0097] The first module is used to obtain the spray volume required for salt spray testing, and determine the height and pressure of multiple spray towers set at the bottom of the salt spray chamber based on the spray volume;

[0098] The second module is used to heat the salt solution stored at the bottom of the salt spray chamber to a set temperature, and then control the spray towers at a set pressure to spray the salt solution into the interior of the salt spray chamber in the form of a spray to perform salt spray testing on the testing equipment; wherein, the bottom ends of the multiple spray towers are connected to the salt solution;

[0099] It should be noted that in the embodiments provided by the present invention, the salt solution is heated to a specified experimental temperature (e.g., 35°C) by high temperature and high pressure, and the spray tower sprays the salt solution to corrode the materials of the test equipment.
