In particular, this step starts when the key equipment starts to be in place for a long time. The execution cycle is determined by the test and maintenance cycle of the key equipment. All data obtained by the execution can be used as the output content of the test result output component.
[0038] Step 5: Obtain real test data and health management results
[0039] The data acquisition docking component of the health management PHM subsystem obtains the real test data of the test result output component through the interface. The health management PHM operation service engine calls the adaptive incremental model contained in the PHM model component, executes the model with the real test data as input and outputs the operation result; in particular, the way the health management PHM operation service engine calls the model is confirmed by the corresponding adaptive incremental model, and the calling interface form used by the engine is confirmed according to the needs of the model to achieve the correct operation of the model and output the health management results; further, the output health management results are confirmed according to the model output interface, including parameter monitoring status, fault diagnosis information, fault prediction information, health assessment information, etc.
[0040] Step 6: Update the adaptive incremental model based on the situation
[0041] The adaptive incremental model updates the model itself as needed. This part of the work is completed by the health management PHM operation service engine in conjunction with the model, and adaptive incremental work is carried out based on the characteristics of the model. In particular, the model can support the completion of online learning updates, model fine-tuning, incremental learning, dynamic evolution data learning, and continuous model optimization based on its own characteristics; in particular, the data for this part of the model update comes from real test data, including real-time test data and historical test data; further, the scheduling and parameter input of the data are completed by the health management PHM operation service engine.
[0042] Step 7: Simulation data is sent and PHM expected results are generated

Among them, the health management results obtained according to the real value are processed and converted into the expected health management results.
[0044] Furthermore, the simulation verification requirements are scheduled and allocated by the model update simulation verification control component, and the model update simulation verification control component provides a control or parameter configuration interface to meet requirements for model simulation verification, performance judgment, design indicator benchmarking, etc.
[0045] Step 8: Simulation test program execution
[0046] Execute the test program based on the simulation test resources to obtain the simulation test values of the simulation test resources; in particular, the simulation test resources are used as input to provide corresponding test resources for the engine to generate simulation test values; further, according to the ATML test program, organize the generation logic and parameter composition of the simulation data; further, according to the test signal simulation parameters issued by the test simulation parameter issuing component, confirm the parameter values, parameter sequences, and parameter timings of all the simulation parameters included; in particular, this step can simulate any time and any state of the simulation key equipment; all the data obtained by the execution can be used as the output content of the test result output component.
[0047] Furthermore, based on the ATML test program and simulation data generation logic, the ATML test program provides a logical framework and parameter composition for simulation data generation; by matching the test signal requirements defined by ATML with the simulation test resources, the automatic generation of simulation test signals is realized.
[0048] Step 9: Obtain simulation test data and health management results
[0049] The data acquisition docking component of the health management PHM subsystem obtains the simulation test data of the test result output component through the interface. The health management PHM operation service engine calls the adaptive incremental model contained in the PHM model component, executes the model with the simulation test data as input, and outputs the operation result. In particular, the way in which the health management PHM operation service engine calls the model is confirmed by the corresponding adaptive incremental model, and the calling interface form used by the engine is confirmed according to the needs of the model to achieve the correct operation of the model and output the health management results. Furthermore, the output health management results are confirmed according to the model output interface, including parameter monitoring status, fault diagnosis information, fault prediction information, health assessment information, etc.
[0050] In particular, when receiving simulation test data, the health management results generated by the health management PHM subsystem will be accompanied by attributes, indicating that the results are generated based on simulation test data.
[0051] Step 10: Adaptive incremental model simulation verification update
[0052] The adaptive incremental model carries out updates based on simulation verification as appropriate. This part of the work is completed by the health management PHM operation service engine in conjunction with the model, and adaptive incremental work is carried out based on the characteristics of the model. In particular, the model can support the completion of online learning updates, model fine-tuning, incremental learning, dynamic evolution data learning, and continuous model optimization based on its own characteristics; in particular, the data for this part of the model update comes from simulation test data; further, the scheduling and parameter input of the data are completed by the health management PHM operation service engine.
[0053] In particular, the update work of the adaptive incremental model will be accompanied by attributes, indicating that the result is an update based on the simulation test data results; further, an option can be provided for whether to accept the update and save it.
[0054] Step 11: Model operation evaluation and feedback control

In particular, the adaptive incremental model operation evaluation includes operation evaluation of real test data and simulation test data; further, the simulation test data can be evaluated in different simulation scenarios according to different simulation combinations of test signals and test programs in the ATML test program; further, the next round of simulation verification process can be controlled according to the feedback results.
[0056] Step 12: Continuous model optimization
