If so, use the detection type as the first detection type to obtain a first detection type set. If the detection type does not belong to the sequential detection type, the detection type is used as the second detection type, and the airtightness detection result corresponding to the second detection type is obtained as the initial detection result; Step 335: extracting the airtightness test results corresponding to the first test type set from the airtightness test set to obtain a first test set; Step 336: Sort the sub-detection results in each first detection subset in the first detection set according to the time series to obtain a first ordered detection subset; Step 337: Inputting the sub-detection results of each first ordered detection subset into the same coordinate system, and processing them to obtain a first detection curve, thereby obtaining a first detection curve set; Step 338: Combine each first detection curve in the first detection curve set with the corresponding detection type to obtain a first detection sub-result for the current detection type, and combine each first detection sub-result with the initial detection result to obtain a first detection result.

[0059] In this embodiment, the current airtightness test cycle refers to the time period from the start of the test to the end of the test, also known as a test cycle. During this cycle, the target tire is tested for airtightness multiple times at a predetermined frequency.

[0060] In this embodiment, the detection frequency refers to the number of times or time intervals during which the airtightness detection is performed on the target tire within the current airtightness detection cycle. This frequency is determined based on the airtightness detection requirements of the target tire.

[0080] In this embodiment, the detection and analysis standards are pre-set according to tire industry standards and customer needs, and are used to evaluate the benchmark or threshold of the target tire's airtightness performance. These standards may include allowable leakage rate, pressure variation range, etc.

[0081] In this embodiment, the first test result refers to the first comprehensive evaluation result of the target tire's airtightness performance after a series of test steps. This result typically includes multiple sub-analysis results, each corresponding to a different test type or time point.

[0082] In this embodiment, the data analysis result refers to the result obtained after further processing and analysis of the first test result. This may include steps such as data cleaning, data conversion, and statistical analysis, aiming to extract useful information and evaluate the airtightness performance of the target tire.

[0084] In this embodiment, the corresponding critical value refers to a threshold value specified in the test and analysis standard for determining whether the sub-analysis result is qualified. If the sub-analysis result exceeds this critical value, it may indicate that there is a problem with the airtightness performance of the target tire.

[0085] In this embodiment, this refers to a comprehensive evaluation of the target tire's airtightness performance based on a comparison of the data analysis results and the test analysis criteria. This evaluation result may include a conclusion such as qualified, unqualified, or requiring further testing.

[0093] In this embodiment, the critical value corresponding to the sub-analysis standard refers to the threshold between pass and fail set for each sub-analysis result in the test analysis standard. If the sub-analysis result exceeds this critical value, it may indicate that the tire's airtightness performance in that aspect does not meet the standard.

[0094] In this embodiment, the first critical difference refers to the difference between the sub-analysis result and the critical value of the corresponding sub-analysis standard.
