Example two
Referring to fig. 3, the invention further provides an aging test method of the intense pulse light therapeutic apparatus, which is applied to the aging test device of the intense pulse light therapeutic apparatus according to the first embodiment; the aging test method comprises the following steps:
s1, placing the therapeutic apparatus on the measurement detection position 21, inserting a lamp cap of the therapeutic apparatus into a lamp cap window 31 of the measurement box 30, and connecting the electrical interface 22.
S2, starting the aging test equipment, enabling the voltage transformation adjusting assembly 50 to start adjusting input voltage according to a voltage change rule, and enabling the measuring module to continuously measure the running state of the therapeutic instrument so as to obtain first performance parameter data; the measuring module comprises a temperature measuring unit, a current measuring unit and a light intensity measuring unit, and the first performance parameter data and the second performance parameter data respectively comprise feedback current, temperature and light intensity of the therapeutic instrument.

In this embodiment, it is further described that the aging detection method further includes:
and S4, setting an objective function to maximize aging efficiency by adopting a voltage optimization algorithm, and updating the voltage change rule to obtain an optimized voltage change rule.
The reason for choosing the voltage optimization algorithm is to find the optimal voltage setting for an efficient burn-in test, and the optimization algorithm can iterate and adjust the voltage variation rules according to a given objective function (in this case maximizing the burn-in efficiency) to obtain the best results.
The objective function is that the optimization process defines a specific index for which optimization is desired. In this scenario, the objective function is to maximize the burn-in efficiency, which can be understood as the percentage or degree of burn-in testing completed per unit time, which can be improved by optimizing the voltage settings. The system can iteratively update the voltage change rule according to the set objective function. The voltage variation rules determine how the input voltage varies over time, and the optimization algorithm adjusts these rules based on performance feedback and historical data to find the optimal voltage setting.
After processing by the optimization algorithm, an optimized voltage change rule is obtained. The rule is based on an optimization target of an algorithm and a learning result of historical data, so that the aging test process can be guided better, and the test efficiency and accuracy are improved.
S5, the voltage transformation adjusting component 50 adjusts the input voltage according to the optimized voltage change rule, and detects and obtains second performance parameter data, and second life prediction information is obtained through prediction of the life prediction model.
By adopting the optimized voltage change rule, the efficiency and the accuracy of the aging test are improved, which is helpful for shortening the test period, reducing the energy consumption and improving the accuracy of life prediction of the intense pulse light therapeutic instrument.
S6, synthesizing the first life prediction information and the second life prediction information, and analyzing to obtain the life information of the therapeutic instrument. Combining the life prediction information of the first and second rounds, and comparing the two data helps to verify the accuracy of the life prediction model and further optimize the model parameters.
It should be noted that, in this scheme, in order to further improve the process of life prediction of the therapeutic apparatus, the voltage change rule is updated by the voltage optimization algorithm, so that the input voltage change frequency of the therapeutic apparatus is faster, so as to accelerate the life test behavior in the actual process, and in order to avoid the life prediction having a larger error due to the too fast voltage change frequency, the error behavior of single prediction is eliminated by integrating the first life prediction information and the second life prediction information.
Meanwhile, it is easy to understand that a voltage optimization algorithm can be adopted to update the voltage change rule for multiple times, so that the accuracy of the life information is further improved.
In this embodiment, it is specifically described that step S3 specifically includes:
s31, inquiring historical parameter data of the therapeutic apparatus, inputting the historical parameter data into a called life prediction model, and performing model training on the life prediction model to obtain a trained life prediction model;
historical parameter data is typically a life parameter inherent at the factory, one of which can be obtained by querying, and has important value in predicting life and performance degradation of the device. By querying and utilizing these data, the accuracy and reliability of the life prediction model may be improved.
And inputting the queried historical parameter data into a life prediction model for model training. The process utilizes the characteristics and the trend of the historical data, and trains and optimizes the model by learning the mode and the rule in the historical data; the model is based on patterns and relationships in the historical data, and finally a trained life prediction model is obtained. The model has the capability of predicting the service life of equipment according to historical data, and can provide important references and bases for subsequent aging tests.
S32, preprocessing the first performance parameter data; the preprocessing comprises data cleaning and normalization processing;
the purpose of data cleansing is to remove or correct erroneous, abnormal or incomplete data. In the performance parameter data, there may be some outliers, missing values, or incorrectly formatted data. The data cleaning ensures the accuracy and consistency of the data and avoids the influence of abnormal data on the subsequent analysis.
Normalization is the tuning of data to a uniform standard or range for better comparison and analysis. In performance parameter data, the data ranges of different parameters may be different, and the normalization process may convert them to a uniform scale for easier analysis and comparison.
S33, taking the input voltage as a first-order parameter, taking the preprocessed first performance parameter data as a second-order parameter, inputting the first performance parameter data into a trained life prediction model to predict the service life of the therapeutic instrument, and obtaining first life prediction information;
the input voltage is used as a first-order parameter, the preprocessed first performance parameter data is used as a second-order parameter to be input into a life prediction model, and the input voltage is selected because the input voltage has direct influence on the performance and the service life of the therapeutic apparatus; while the performance parameter data, as a second order parameter, can provide more information about the device performance state and degradation.
S34, analyzing the trend of life variation of the first life prediction information under different input voltages;
knowing the trend of life prediction information over different input voltages is important to evaluate the performance degradation of the device. By observing the trend, it can be understood how the voltage variation affects the performance and the service life of the device. This helps predict the performance and potential risk of the device during future use.
The analysis results provide key information about the performance degradation patterns and trends of the device at different voltages. This information helps to understand the degradation mechanism of the device and guides subsequent maintenance and optimization measures. For example, if a dramatic drop in the performance of a device is found at a certain voltage range, measures may need to be taken to adjust or limit the use within that range.
S35, judging whether the fluctuation value of the first life prediction information is stable in a preset threshold range, if not, continuously adjusting the input voltage according to a voltage change rule and predicting life information; if so, the first life prediction information tends to be stable.
Judging whether the fluctuation value of the first life prediction information is stable within a preset threshold range is a key step of ensuring prediction accuracy and stability. By observing the variation of the fluctuation value, the reliability and stability of the prediction information can be known. The reasonable threshold range is helpful for accurately judging the performance state of the equipment and the reliability of life prediction.
The traditional equipment aging detection method lacks of monitoring and judging the fluctuation value of the prediction information, which leads to misjudgment of the performance state of the equipment or error of management decision. By introducing the judging method of the preset threshold range, the performance state of the equipment and the stability of the prediction information can be more accurately estimated, so that a more reliable decision basis is provided.
In this embodiment, it is specifically described that step S4 specifically includes:
s41, setting an objective function to maximize aging efficiency, and determining adjustable parameters in a voltage change rule; the maximum value, the minimum value and the change rate of the parameter voltage can be adjusted;
an objective function is predefined, here maximizing the ageing efficiency; the burn-in efficiency can be measured by the rate of change of the performance of the test equipment during simulated use, and the objective function will direct the optimization algorithm to optimize the direction to increase the test rate and quickly converge to the real life.
To achieve maximum aging efficiency, it is necessary to determine adjustable parameters in the voltage variation rules. These adjustable parameters include the maximum value, minimum value, and rate of change of the voltage. By adjusting these parameters, fine control and optimization of the device performance state may be achieved. The maximum and minimum values of the voltage determine the range of voltage variation, and the rate of change determines the speed of voltage regulation. Proper setting of these parameters is critical to control the aging process of the device and to achieve maximized aging efficiency.
S42, calling a simulated annealing algorithm as a voltage optimization algorithm, and setting an initial temperature, a cooling rate and a stop threshold of the simulated annealing algorithm; the initial state is set to the voltage change rule currently in use or a baseline setting.
S43, carrying out iteration on the voltage change rule for a plurality of times through a simulated annealing algorithm to obtain a plurality of new voltage parameters. Along with the iteration, the algorithm evaluates and screens out a set of voltage parameters which can realize high aging efficiency in a test environment.
At this stage, gradually approaching the optimal voltage setting through multiple iterations; because the simulated annealing algorithm has certain randomness, the simulated annealing algorithm can effectively avoid the processing process from being trapped in local optimum, and increases the probability of finding the global optimum solution.
S44, finishing new voltage parameters obtained in each iteration in the iteration process to form an optimized voltage change rule.
The step involves the arrangement of the iterative process, the comparison of the different parameter combinations produced, and the selection of the optimal parameters as the final voltage variation rule; this rule should be able to provide optimal burn-in efficiency during testing, ensuring test accuracy and reliability.
In this embodiment, specifically, step S43 specifically includes:
s431, in each iteration, randomly selecting one voltage parameter for adjustment to obtain a new voltage parameter, and calculating a corresponding function value; judging whether the function value is larger than the initial temperature, if so, reserving new voltage parameters; if not, discarding the new voltage parameter.
One key feature of the simulated annealing algorithm is the criterion of accepting or rejecting new solutions; if the new voltage parameter results in a better objective function value (aging efficiency) than the previous value (i.e., higher aging efficiency), then the new parameter is accepted; if the new function value does not improve, it is still likely to be accepted according to the probabilistic nature of the algorithm, but the probability decreases with decreasing temperature; this possibility of accepting a bad solution allows the algorithm to jump out of local optimization, increasing the chance of finding a globally optimal solution.
S432, sequentially reducing the temperature parameters in the iteration process, reducing the difference between the function value and the stop threshold value until the corresponding function value reaches the stop threshold value, and obtaining a plurality of new voltage parameters.
Gradually reducing the temperature parameter of the simulated annealing algorithm along with the increase of the iteration times; this step is a "cool down" process in simulated annealing; as the temperature decreases, the probability of accepting a new solution that is worse than the current solution decreases. When a preset stopping threshold is reached, namely the difference between the objective function value and the optimal value is reduced to the minimum or the temperature is reduced to a certain threshold, the algorithm stops, and the current optimal voltage parameter is output.
Steps S431 and S432 are the core of the simulated annealing optimization process. S431 maintains a search for the globally optimal solution by a random exploration and probability acceptance mechanism, while S432 ensures that the algorithm eventually converges by controlling the temperature drop, and terminates the iteration when appropriate. The whole process is a dynamic balancing process, and is continuously adjusted between 'exploration' (searching for new solutions through random perturbation) and 'utilization' (preserving good solutions and fine-tuning). Finally, the process generates a series of optimized voltage parameters, which aims to improve the efficiency and the accuracy of the aging test and ensure that the performance of the intense pulse light therapeutic instrument in the accelerated aging test can accurately reflect the behavior of the intense pulse light therapeutic instrument in actual use.
