Description

Technical Field

[0001] This invention provides a simulation test system and method for an ignition system, relating to the field of ground testing technology for aviation equipment. Background Technology

[0002] An aero-engine ignition system typically comprises an ignition device, ignition cable, and ignition electrode. Its operation is influenced by factors such as power supply characteristics, high-voltage discharge link, air pressure, temperature, and airflow. During research and development, production, and maintenance, it is usually necessary to conduct simulated operational tests on the ignition system without relying on full-engine testing. This allows for the acquisition of data such as input voltage, input current, output voltage, output current, spark frequency, ignition duration, ignition images, and environmental parameters. Based on this data, the reliability and consistency of the ignition system under conditions such as high altitude and low pressure, temperature variations, and airflow disturbances can be assessed.

[0003] Existing ignition system testing methods often focus on single electrical performance testing or static testing under fixed environments, lacking a unified time-series correlation between the environmental simulation process, ignition electrical parameter measurement process, and ignition image analysis process. During multi-condition switching, anomaly reproduction, or long-term continuous testing, inconsistencies in sampling triggering, time stamping, and evaluation scales across different data channels easily lead to reliance on manual observation or offline comparison for judging ignition effectiveness, discharge stability, and operational adaptability. Furthermore, the test objects and operational boundaries of ignition devices, ignition cables, and ignition nozzles differ. Without a linkage control and data fusion evaluation mechanism oriented towards the simulated working process, it is difficult to form repeatable and traceable test conclusions, and it is also detrimental to the localization and analysis of abnormal states in the ignition system. Summary of the Invention

[0004] In view of the aforementioned problems, a first aspect of the present invention provides a method for simulating the operation of an ignition system, comprising: Acquire ignition system simulation test task, wherein the ignition system simulation test task includes target simulation condition information and test criterion configuration information; A working condition test sequence is generated based on the ignition system simulation working test task. The working condition test sequence includes at least one simulated working condition stage, and each simulated working condition stage carries a corresponding working condition identifier and test stage identifier. The current simulated working condition is determined and established according to the working condition test sequence, and working condition ready information is generated after the current simulated working condition meets the preset stability conditions. In response to the operating condition readiness information, the system under test is controlled to perform an ignition test, and a synchronization acquisition command carrying a synchronization time identifier is generated to acquire multi-source test data during the ignition test process. The multi-source test data are associated according to the operating condition identifier, the test stage identifier, and the synchronization time identifier to generate an ignition system simulation working test data fragment; Multi-source feature analysis is performed on the simulated working test data segment of the ignition system to obtain the working response features of the ignition system; Based on the ignition system's operating response characteristics and the test criterion configuration information, the ignition operating status of the ignition system under test is evaluated under the current simulated operating condition, and the current operating condition test evaluation result is obtained.

[0005] In another aspect, embodiments of the present invention also provide an ignition system simulation working test system for implementing the above-mentioned method, comprising: an environmental simulation unit, an ignition drive and switching unit, a multi-source data acquisition unit, a synchronization control unit, and a data processing and evaluation unit; The environmental simulation unit is used to establish the current simulated operating condition of the ignition system under test, and outputs the operating condition readiness information after the current simulated operating condition meets the preset stability conditions. The ignition drive and switching unit is used to drive the ignition system under test to perform an ignition test. The multi-source data acquisition unit is used to acquire multi-source test data during the ignition test process; The synchronization control unit is connected to the environmental simulation unit, the ignition drive and switching unit and the multi-source data acquisition unit respectively, and is used to coordinate the acquisition of the ignition test and the multi-source test data according to the operating condition readiness information. The data processing and evaluation unit is connected to the synchronization control unit and the multi-source data acquisition unit, respectively, and is used to generate a working condition test sequence, perform correlation processing and feature analysis on the multi-source test data, and generate the current working condition test evaluation result.

[0006] The present invention provides an ignition system simulation testing system and method, the beneficial effects of which are mainly reflected in the following aspects: First, this invention generates a test sequence of operating conditions by simulating the working test of the ignition system, and makes each simulated working condition stage carry a corresponding working condition identifier and test stage identifier. This enables the unified organization of the environment establishment, ignition test and data acquisition process under different simulated working conditions, avoiding problems such as unclear working condition boundaries, chaotic test order or difficulty in attributing test data in the process of multi-working condition testing, thereby improving the standardization and repeatability of ignition system simulated working test.

[0007] Secondly, this invention generates condition-ready information after the current simulated operating condition meets preset stability conditions, and performs ignition testing and multi-source test data acquisition in response to this condition-ready information, ensuring that the ignition action occurs in a stable simulated operating environment. Simultaneously, by using a synchronous acquisition command carrying a synchronization time identifier, electrical parameters, environmental parameters, and ignition image data during the ignition test can be acquired or correlated within the same test sequence, reducing data mismatch caused by inconsistent trigger times of different acquisition channels.

[0008] Furthermore, this invention correlates multi-source test data according to operating condition identifiers, test stage identifiers, and synchronization time identifiers to generate ignition system simulated operating test data segments. Based on these test data segments, multi-source feature analysis and ignition operating status evaluation are performed. Therefore, it is possible to comprehensively utilize power supply status, discharge status, environmental status, and ignition image status to judge the ignition system under test, reducing misjudgments caused by single electrical parameter detection or manual image observation, and improving the accuracy of test evaluation results under current simulated operating conditions.

[0009] Furthermore, this invention can generate comprehensive test results based on the current test evaluation results corresponding to each simulated operating condition stage, and record the operating condition test sequence, test data, evaluation results, and anomaly location information in the test report. This enables testers to trace the environmental parameters, electrical parameters, and ignition image data at the time of the anomaly based on the operating condition identifier, test stage identifier, and synchronization time identifier, thereby improving the verifiability and traceability of test conclusions and providing data support for the research and development verification, production inspection, and maintenance troubleshooting of ignition systems.

[0011] Figure 2 This is a schematic diagram of the structure of the ignition system simulation test system provided in an embodiment of the present invention. Detailed Implementation

[0012] To make the technical solutions, the technical problems solved, and the technical effects of this application clearer, the technical solutions of this application will be described in detail and completely below with reference to the accompanying drawings in the embodiments of this application.

[0013] It is understood that the specific embodiments described herein are merely exemplary representations of the technical solutions of this application, used to explain the technical concept of this application, and are not intended to limit the scope of protection of this application. In other embodiments of this application, the technical details described below can be reasonably adjusted, replaced, or modified according to the needs and conditions of actual application scenarios. As long as they do not depart from the core inventive concept of this application, such modifications and refinements should be considered to fall within the scope of protection of this application.

[0014] In the description of this application, it should be noted that the terms "an embodiment," "an exemplary embodiment," "some embodiments," etc., mean that the specific technical features, structures, or characteristics described in connection with the embodiment or example are included in at least one implementation of the technical solution of this application. The same expressions appearing in different places throughout this application do not necessarily refer to the same embodiment.

[0015] Furthermore, to avoid obscuring the core concept of this application, the well-known principles and operational details of commonly used data acquisition technologies, network communication protocols, computer programming languages, and conventional signal processing algorithms familiar to those skilled in the art will not be elaborated upon in the embodiments. The focus will be on the core innovative steps and system architecture that distinguish the technical solution of this application from the prior art. The accompanying drawings are also only illustrative and do not represent the sole limitation on the proportions and physical implementation of the structures and processes therein.

[0016] In the research, development, production, testing, and maintenance of aero-engine ignition systems, ignition devices, ignition cables, and ignition nozzles typically require simulated operational testing under conditions close to actual use. The inventors discovered in their analysis that the reliability of an ignition system is not determined solely by a single electrical performance parameter. Correlation exists between input power supply status, output high-voltage discharge status, spark frequency, air pressure and temperature conditions at the ignition nozzle, airflow disturbance, and ignition image characteristics. When these factors are collected or judged independently by different devices, while individual test data can be obtained, it is difficult to reconstruct the complete working process of the ignition system under the same simulated conditions. This is especially true under complex conditions such as high-altitude low-pressure, low-temperature or high-temperature, airflow disturbance, and continuous ignition, where isolated test data, inconsistent trigger times, and difficulties in reproducing abnormal phenomena are common problems.

[0017] Further analysis revealed that the fundamental problem in the existing testing process lies in the lack of a unified operational logic between environmental control, ignition system operation, electrical parameter acquisition, and ignition process observation. Testers typically set environmental conditions first, then start the ignition system, and subsequently read voltage and current data, spark frequency data, and image data. While this method can complete basic testing, it cannot guarantee a strict correspondence between the moment environmental parameters reach a stable state, the ignition trigger moment, the electrical signal sampling moment, and the image acquisition moment. When the ignition system exhibits intermittent ignition, distorted discharge waveforms, ignition position deviation, spark brightness decay, or ignition failure, it is difficult to accurately determine whether the anomaly is caused by abnormal ignition device output, abnormal ignition cable transmission, abnormal ignition nozzle discharge, or changes in environmental conditions or airflow disturbances.

[0018] Based on the above understanding, the inventors propose an ignition system simulation testing system and method. The core concept is not simply to add testing equipment, but rather to organize environmental simulation control, ignition system power supply drive, multi-source status acquisition, ignition image analysis, and test conclusion generation into a closed-loop testing process within the same time sequence, using simulated operating conditions as the main thread. By establishing operating condition identifiers, test stage identifiers, and synchronization time identifiers for each test process, the electrical parameters, environmental parameters, and ignition images generated by the ignition device, ignition cable, and ignition nozzle under different simulated operating conditions can be mapped to the same test segment. Based on this test segment, the discharge stability, ignition effectiveness, and operating condition adaptability of the ignition system are then judged, thereby improving the accuracy, repeatability, and traceability of the test results.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. Figure 1 This is a flowchart illustrating an embodiment of the ignition system simulation testing method provided by the present invention. The ignition system simulation testing method provided in this embodiment includes: Step S100: Obtain the ignition system simulation test task, wherein the ignition system simulation test task includes target simulation condition information and test criterion configuration information; Step S200: Generate a working condition test sequence according to the ignition system simulated working test task. The working condition test sequence includes at least one simulated working condition stage, and each simulated working condition stage carries a corresponding working condition identifier and test stage identifier. Step S300: Determine and establish the current simulated working condition according to the working condition test sequence, and generate working condition ready information after the current simulated working condition meets the preset stability conditions; Step S400: In response to the operating condition ready information, control the ignition system under test to perform an ignition test and generate a synchronization acquisition command carrying a synchronization time identifier to acquire multi-source test data during the ignition test process. Step S500: Associate the multi-source test data according to the operating condition identifier, the test stage identifier and the synchronization time identifier to generate an ignition system simulated working test data segment; Step S600: Perform multi-source feature analysis on the simulated working test data segment of the ignition system to obtain the working response features of the ignition system; Step S700: Based on the ignition system's working response characteristics and the test criterion configuration information, evaluate the ignition working state of the ignition system under test under the current simulated working condition, and obtain the current working condition test evaluation result.

[0020] In some embodiments, the method further includes: Step S800: Generate a comprehensive test result for the ignition system simulation operation based on the current operating condition test evaluation results corresponding to each simulated operating condition stage, and output a test report. The test report includes the operating condition test sequence, test data for each simulated operating condition stage, current operating condition test evaluation results, comprehensive test results for the ignition system simulation operation, and test conclusions. Furthermore, if the comprehensive test result for the ignition system simulation operation indicates an anomaly, the test report also includes anomaly location information.

[0021] The implementation details of the above steps will be described in detail below with reference to specific embodiments.

[0022] In step S100, acquiring the ignition system simulation test task is the initial step in the entire simulation test process. Its purpose is to uniformly define the scope of the ignition system under test, the boundaries of the simulation environment, the test items, and the test evaluation criteria before the test begins. Since the ignition system simulation test involves multiple test objects such as the ignition device, ignition cable, and ignition nozzle, as well as simulated operating conditions such as air pressure, temperature, and airflow state, and various types of test data such as input electrical parameters, output electrical parameters, spark frequency, and ignition images, this embodiment centrally manages the above information through the ignition system simulation test task. This allows subsequent operating condition test sequence generation, environmental simulation control, ignition trigger control, synchronous data acquisition, and test result evaluation to all be performed based on the same task information. Therefore, mismatches between test objects, environmental settings, acquisition channels, and evaluation criteria can be avoided, improving the standardization and traceability of the simulation test process.

[0023] In one alternative implementation, step S100 may include steps S110 to S150.

[0024] Step S110: Receive test task input information. The test task input information can be entered by the tester through the test control interface, or it can be read by the host computer test software from a pre-established test task template, test plan file or product testing process file.

[0025] The test task input information includes at least the test object information of the ignition system under test, the target simulated operating condition information, the test item configuration information, and the test criterion configuration information. By receiving the above information before the test begins, the test system can complete the task boundary confirmation before executing the ignition action, reducing the risk of test omissions, incorrect channel selection, or incorrect criterion references caused by manual temporary settings.

[0026] Step S120: Analyze the test object information to determine the ignition device, ignition cable, and ignition nozzle participating in this test in the ignition system under test.

[0027] The test object information includes at least the object identifiers of the ignition device, ignition cable, and ignition nozzle. The object identifier can be a product number, workstation number, channel number, QR code, RFID code, or an object index generated internally by the test system. To facilitate subsequent data association, the test object information may also include the ignition device's model and specifications, rated input voltage range, power supply type, test installation location, ignition cable connection port, cable length or cable number, ignition nozzle installation location, adapter interface, and corresponding observation window. By parsing the test object information, the test system can determine the ignition link that needs to be driven and the data acquisition channels that need to be activated in this test, thus ensuring that the subsequently acquired input electrical parameters, output electrical parameters, and ignition images can be accurately attributed to the corresponding ignition device, ignition cable, and ignition nozzle.

[0028] Step S130: Analyze the target simulated working condition information to determine the working environment that the ignition system under test needs to simulate in this test.

[0029] The target simulated operating condition information includes at least target air pressure, target temperature, and target airflow state. The target air pressure defines the pressure conditions of the simulated environment where the ignition nozzle is located, corresponding to different test scenarios such as low pressure or normal pressure. The target temperature defines the temperature conditions of the simulated space where the ignition device, ignition cable, or ignition nozzle is located. The target airflow state defines the airflow interruption, airflow direction, flow rate, or velocity target near the ignition nozzle. Depending on the test requirements, the target simulated operating condition information may also include operating condition holding time, allowable deviation for operating condition stability, operating condition switching sequence, and operating condition recovery conditions. By parsing the target simulated operating condition information, subsequent environmental simulation units can establish simulated operating conditions according to clearly defined environmental control objectives, and provide a basis for determining whether the current simulated operating condition meets the ignition test conditions.

[0030] Step S140: Parse the test item configuration information to determine the test items and data collection content to be executed in this ignition system simulation test.

[0031] The test item configuration information may include one or more of the following: input voltage test, input current test, output voltage test, output current test, spark frequency test, ignition image acquisition, continuous ignition test, single ignition test, and multi-condition cyclic test. The test item configuration information may also include ignition triggering method, ignition duration, ignition interval, sampling frequency, sampling duration, high-speed image acquisition frame rate, image acquisition start time, image acquisition end time, and data storage requirements. By parsing the test item configuration information, the test system can determine the test function modules that need to be called subsequently and can complete the acquisition preparation of the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit before the ignition action occurs.

[0032] Step S150: Analyze the test criterion configuration information to determine the judgment conditions to be used when evaluating the ignition system under test.

[0033] The test criterion configuration information may include the allowable range of input power supply, the allowable range of output voltage, the allowable range of output current, the allowable range of spark frequency, ignition duration requirements, ignition image validity requirements, environmental parameter stability requirements, and anomaly judgment rules. The ignition image validity requirements can be used to determine whether the ignition nozzle has achieved effective ignition, whether the ignition area is within the preset observation area, and whether the ignition brightness or ignition duration meets the test requirements. The anomaly judgment rules can be used to identify states such as abnormal power supply, abnormal output, ignition failure, unstable discharge, missing images, or unstable environmental conditions. By incorporating the test criterion configuration information into the ignition system simulation test task, the subsequent evaluation process can avoid relying on subjective human observation and instead perform a consistency evaluation of the same test data segment based on pre-configured judgment conditions.

[0034] After completing steps S110 to S150, the testing system can perform a consistency check on the test object information, target simulated operating condition information, test item configuration information, and test criterion configuration information. The consistency check may include detecting whether the test object has a corresponding acquisition channel, whether the target simulated operating condition is within the controllable range of the environmental simulation unit, whether the test item has a corresponding sensor or acquisition device, whether the test criterion matches the test item, and whether the ignition trigger parameters are compatible with the power supply type and rated operating range of the ignition system under test. When the consistency check passes, a valid ignition system simulation test task is generated; when the consistency check fails, the testing system can output a task configuration error message and prohibit entry into subsequent ignition test steps until the test task input information is corrected. This processing method can detect task configuration errors before the ignition system is actually powered on and the simulated operating condition is actually established, improving the safety and reliability of the testing process.

[0035] Through step S100, this embodiment can form a structured ignition system simulation test task in the initial stage of testing, unifying the test object, simulated operating conditions, test items, and evaluation criteria. In subsequent step S200, when generating the operating condition test sequence, the target simulated operating condition information and test item configuration information in the ignition system simulation test task can be directly called. In subsequent step S500, when generating ignition system simulation test data fragments, the collected data can be attributed based on the test object information. In subsequent step S700, when performing test evaluation, the ignition system operating response can be automatically determined based on the test criterion configuration information. Therefore, step S100 is not only used to receive test parameters but also to establish the data organization foundation and evaluation basis throughout the entire simulation test process, thereby ensuring that the ignition system simulation test results have good repeatability, comparability, and traceability.

[0036] In step S200, generating a test sequence based on the ignition system simulation test task is the process of converting the task information obtained in step S100 into an executable test procedure. Since ignition system simulation tests are typically not performed under a single environmental condition, but rather require observing the ignition system's response under different air pressures, temperatures, airflow states, and ignition triggering methods, this embodiment does not immediately initiate the test based on the target simulation condition information. Instead, it first arranges the simulation conditions to be executed, ignition actions, and data acquisition actions into a test sequence with a predetermined order. This test sequence ensures that environment setup, ignition triggering, synchronous acquisition, and data evaluation are all performed according to predetermined stages, thereby guaranteeing clear test boundaries between different simulation conditions and ensuring that subsequently generated ignition system simulation test data segments accurately correspond to specific operating condition stages.

[0037] In one alternative implementation, step S200 may include steps S210 to S250.

[0038] Step S210: Read the target simulation working condition information, test item configuration information and test criterion configuration information in the ignition system simulation working test task, and determine the working condition range and test execution range that need to be covered in this test.

[0039] The operating condition range is defined at least by the target air pressure, target temperature, and target airflow state, and the test execution range is defined at least by the test items, ignition triggering method, sampling duration, and number of tests. For test tasks that only require verification under a single simulated operating condition, the test system can define that single simulated operating condition as a simulated operating condition stage. For test tasks that require verification under multiple operating conditions, the test system can form multiple simulated operating condition stages based on the combination relationships between multiple target air pressures, multiple target temperatures, or multiple target airflow states. Through this approach, the actual number of simulated operating conditions that need to be executed can be determined before the test, avoiding disorderly switching between unplanned operating conditions by the subsequent environmental simulation unit.

[0040] Step S220: Divide the simulated working condition stages according to the working condition range, and configure a working condition identifier and a test stage identifier for each simulated working condition stage.

[0041] The operating condition identifier is used to indicate the environmental attributes of the current simulated operating condition, so that the subsequently acquired electrical parameters, environmental parameters, and ignition image data can be mapped to specific target air pressure, target temperature, and target airflow state. The test phase identifier is used to indicate the position of the current simulated operating condition phase in the entire test process, and can be used to distinguish at least one of the following phases: preparation phase, environment establishment phase, operating condition stabilization phase, ignition execution phase, data acquisition and holding phase, and operating condition recovery phase.

[0042] By setting operating condition identifiers and test phase identifiers for the simulated operating condition phase, test data of the same ignition system under test under different environmental conditions can be clearly distinguished, and a basis is provided for the subsequent step S500 to generate ignition system simulated working test data segments according to the operating condition identifier, test phase identifier, and synchronization time identifier.

[0043] Step S230: Configure environmental control targets for each simulated operating condition stage. The environmental control targets include at least target air pressure, target temperature, and target airflow state, and may further include operating condition establishment method, operating condition holding time, stability allowable deviation, and operating condition exit conditions.

[0044] The operating condition establishment method is used to define the control method by which the environmental simulation unit adjusts from the current environmental state to the target simulated operating condition. For example, pressure regulation, temperature regulation, and airflow regulation are used to bring the simulated space where the ignition nozzle is located to the target environment. The operating condition holding time is used to limit the time that needs to be maintained after the target simulated operating condition has reached stability, so that the ignition system can be tested under relatively stable environmental conditions. The stability allowable deviation is used to determine whether the actual air pressure, actual temperature, and actual airflow state have met the conditions for entering the ignition test.

[0045] The exit conditions are used to determine whether to enter the next simulation phase, perform environmental recovery, or stop the test after the current simulation phase ends. By configuring environmental control objectives for each simulation phase, environmental simulation control can have clear control objects and judgment criteria, avoiding premature execution of ignition tests before the environment is stable.

[0046] Step S240: Configure ignition trigger parameters and data acquisition parameters for each simulated operating condition stage according to the test project configuration information. The ignition trigger parameters may include the ignition trigger method, ignition duration, number of ignitions, ignition interval time, and ignition channel information. For tasks requiring testing the overall operating status of the ignition device, ignition cable, and ignition nozzle, the ignition channel information is used to determine the ignition link to be tested connected to the ignition drive and switching unit. The data acquisition parameters may include the sampling frequency, sampling start and end times, sampling channels, and sampling duration of the electrical parameter acquisition unit; the sampling channels and recording period of the environmental parameter acquisition unit; and the image acquisition frame rate, acquisition start time, acquisition end time, and observation area information of the high-speed ignition image acquisition unit. These data acquisition parameters correspond to the ignition trigger parameters, enabling the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data to be synchronously acquired around the same ignition action. This configuration method ensures that each simulated operating condition stage not only has environmental targets but also clearly defined ignition execution conditions and data acquisition conditions.

[0047] Step S250: Based on the environmental change relationships and test safety constraints between the simulated operating condition stages, determine the execution order of each simulated operating condition stage and generate the operating condition test sequence. Specifically, when multiple simulated operating condition stages involve changes in temperature, air pressure, or airflow state, the test system can sort the simulated operating condition stages according to the adjustment capability of the environmental simulation unit, the operating condition switching time, and the equipment protection requirements, so that the environmental changes between adjacent simulated operating condition stages are within a controllable range. For test tasks that require completing routine operating condition verification before entering extreme operating condition verification, the test system can configure the routine simulated operating condition stage first and the low-pressure, high-temperature, low-temperature, or strong airflow disturbance simulated operating condition stages later. For test tasks that require repeatable verification, the test system can configure multiple simulated operating condition stages that are executed continuously or at intervals under the same environmental control objective. This sorting method can reduce unnecessary repeated environmental switching, improve test efficiency, and reduce the risk of equipment protection actions or test interruptions caused by sudden changes in operating conditions.

[0048] After generating the operating condition test sequence, the test system can perform integrity and executability checks on the sequence. The integrity check confirms that each simulated operating condition stage has an operating condition identifier, a test stage identifier, an environmental control target, ignition trigger parameters, and data acquisition parameters. The executability check confirms that the environmental control target for each simulated operating condition stage is within the control range allowed by the environmental simulation unit, the ignition trigger parameters match the power supply type and test items of the ignition system under test, and the data acquisition parameters match the available channels of the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit. When the check passes, the test system sends the operating condition test sequence to the synchronization control unit and the environmental simulation unit for subsequent step S300 to establish the current simulated operating condition. When the check fails, the test system outputs an operating condition test sequence configuration anomaly information and can indicate the operating condition stage, control target, or acquisition parameters that need correction based on the anomaly type.

[0049] Through the aforementioned step S200, this embodiment can transform the ignition system simulation test task into an executable test process organized according to operating condition stages, ensuring that each simulated operating condition stage has clear environmental control objectives, ignition triggering requirements, and data acquisition requirements. This operating condition test sequence can support ignition performance verification under a single operating condition, as well as continuous or cyclic testing under multiple pressure, temperature, and airflow conditions. Since each simulated operating condition stage carries an operating condition identifier and a test stage identifier, the subsequently acquired input electrical parameters, output electrical parameters, environmental parameters, and ignition image data can be aggregated according to the same operating condition stage, thereby improving the consistency of multi-condition test data organization and facilitating subsequent comparative evaluation of the ignition effectiveness, discharge stability, and operating condition adaptability of the ignition system under different simulated operating environments.

[0050] In step S300, the environmental simulation unit establishes the current simulated operating condition according to the operating condition test sequence. This is a process of actively constructing and confirming the working environment of the ignition system under test before executing the ignition action. Since the ignition state and discharge stability of the ignition system are affected by air pressure, temperature, and airflow conditions, if the ignition test is initiated before the environmental parameters reach the target state or are still in a state of significant fluctuation, the acquired electrical parameters and ignition images will be difficult to accurately reflect the actual working response of the ignition system under test under the target simulated operating condition. Therefore, in this embodiment, before entering the ignition test, the environmental simulation unit is controlled according to the environmental control target corresponding to the current simulated operating condition stage, and the environmental parameter acquisition unit is used to confirm the actual air pressure, actual temperature, and actual airflow conditions. Only after the current simulated operating condition meets the preset stability conditions is the operating condition ready information generated, allowing the subsequent step S400 to execute the ignition test. This method ensures that the ignition test occurs in a clear, stable, and traceable simulated working environment, thereby improving the effectiveness and consistency of the test results.

[0051] In one alternative implementation, step S300 may include steps S310 to S360.

[0052] Step S310: Read the current simulated operating condition stage in the operating condition test sequence, and extract the environmental control target, operating condition identifier, and test stage identifier from the current simulated operating condition stage.

[0053] The environmental control objectives include at least target air pressure, target temperature, and target airflow state, and may further include operating condition holding time, allowable stability deviation, and operating condition exit conditions. The test system determines the simulated working environment to be established based on the operating condition identifier, and determines the execution position of the current simulated operating condition stage within the entire test process based on the test stage identifier.

[0054] By first reading the current simulation condition stage, it can be ensured that the control actions of the environmental simulation unit are consistent with the test sequence of the operating conditions generated in step S200, thus avoiding the subsequent test data from being incorrectly attributed due to incorrect operating condition calls.

[0055] Step S320: Send an environment establishment command to the environment simulation unit according to the environmental control target, so that the environment simulation unit adjusts the air pressure, temperature and airflow state of the simulation space where the ignition system is located.

[0056] Specifically, the environmental simulation unit can adjust the air pressure in the simulation space through a pressure regulating mechanism to make the actual air pressure approach the target air pressure; it can control the heating, cooling, or heat preservation of the simulation space or the area where the component under test is located through a temperature regulating mechanism to make the actual temperature approach the target temperature; and it can control the airflow interruption, flow rate, velocity, or airflow direction near the ignition nozzle through an airflow regulating mechanism to match the actual airflow state with the target airflow state. The pressure regulation, temperature regulation, and airflow regulation mentioned above can be executed sequentially according to a preset order, or they can be executed in parallel if equipment conditions permit, in order to shorten the operating condition setup time.

[0057] Step S330: Collect the actual environmental parameters under the current simulated working conditions through the environmental parameter acquisition unit. The actual environmental parameters include at least the actual air pressure, actual temperature and actual airflow state.

[0058] To ensure that environmental parameters can be consistently correlated with subsequent electrical parameters and ignition image data, the actual environmental parameters can carry an operating condition identifier, a test phase identifier, and an environmental acquisition time identifier during acquisition. The environmental acquisition time identifier is used to characterize the time position corresponding to each environmental parameter acquisition.

[0059] By continuously collecting actual environmental parameters, we can obtain the environmental change status during the establishment of the current simulation condition and provide a real-time data basis for judging whether the simulation condition is stable.

[0060] Step S340: Based on the actual environmental parameters and the environmental control target, perform closed-loop adjustment of the current simulated operating condition. Specifically, when the deviation between the actual air pressure and the target air pressure exceeds the corresponding allowable stability deviation, the test system controls the pressure regulating mechanism to continue performing pressure increase, pressure decrease, or holding control; when the deviation between the actual temperature and the target temperature exceeds the corresponding allowable stability deviation, the test system controls the temperature regulating mechanism to continue performing heating, cooling, or heat preservation control; when the actual airflow state does not reach the target airflow state, the test system controls the airflow regulating mechanism to adjust the airflow interruption state, flow rate, or flow velocity.

[0061] The closed-loop adjustment does not change the target simulated operating condition set in the operating condition test sequence, but rather, based on the actual environmental parameters fed back by the environmental parameter acquisition unit, it gradually converges the current simulated operating condition to the corresponding environmental control target.

[0062] This closed-loop adjustment process can reduce the impact of overshoot, hysteresis, or fluctuations during the environment setup process on ignition testing.

[0063] Step S350: Determine whether the current simulated operating condition meets the preset stability conditions.

[0064] The preset stabilization conditions may include the actual air pressure being within the allowable range corresponding to the target air pressure, the actual temperature being within the allowable range corresponding to the target temperature, the actual airflow state meeting the target airflow state requirements, and the above environmental conditions not exhibiting fluctuations exceeding the allowable range within the preset stabilization duration.

[0065] The preset stability conditions may also include the environment simulation unit not outputting a fault state, the simulation space not triggering a safety protection state, and the ignition drive and switching unit not being in an ignition-prohibited state.

[0066] By using both parameter stability conditions and equipment status conditions as the basis for judgment, we can avoid misjudging that the operating condition has stabilized simply because a certain instantaneous sample value meets the requirements, thus ensuring that subsequent ignition tests have a reliable environmental foundation.

[0067] Step S360: When the current simulated operating condition meets the preset stability condition, generate operating condition ready information.

[0068] The operational readiness information may include operational condition identifier, test phase identifier, target air pressure, target temperature, target airflow state, actual air pressure, actual temperature, actual airflow state, stability determination result, and operational condition readiness time identifier.

[0069] The operating condition readiness time identifier is used to characterize the moment when the current simulated operating condition is confirmed to meet the ignition test conditions, and can be used as one of the timing references for the subsequent step S400 to perform ignition triggering and synchronous acquisition.

[0070] After generating the operating condition readiness information, the test system sends it to the synchronization control unit and the ignition drive and switching unit, so that subsequent ignition actions can only be executed under the condition of operating condition readiness.

[0071] If the current simulated operating condition does not meet the preset stability conditions, the test system can continue to perform closed-loop environmental adjustments and continuously collect actual environmental parameters. If the current simulated operating condition still does not meet the preset stability conditions within a preset waiting time, the test system can generate operating condition establishment anomaly information and associate the anomaly information with the corresponding operating condition identifier and test stage identifier. The operating condition establishment anomaly information can be used to indicate that the target air pressure cannot be reached, the target temperature cannot be reached, the airflow state is abnormal, the environmental parameter fluctuation exceeds the limit, or the equipment protection state is triggered. For such anomalies, the test system can stop entering the subsequent ignition test steps, or it can enter the safety recovery process according to the test task configuration. By prohibiting ignition when the operating condition is not ready, invalid test data can be avoided from entering the subsequent evaluation process, and the risk of unnecessary impact on the ignition system under test and the test equipment can be reduced.

[0072] Through step S300, this embodiment can convert the current simulated operating condition from the task configuration state to an actual executable environmental state before the ignition test, and confirm the stability of the environmental state through environmental parameter feedback. Since the operating condition readiness information simultaneously includes target environmental parameters, actual environmental parameters, stability determination results, and operating condition readiness time identifiers, subsequent step S400 can clearly know the environmental conditions corresponding to the ignition action when performing the ignition test, and subsequent step S500 can also correlate the ignition data with the operating condition establishment results when generating the ignition system simulated operating test data segment. Therefore, it can reduce test errors caused by environmental instability, improve the repeatability of test results under different simulated operating conditions, and facilitate accurate evaluation of the ignition system's ignition effectiveness, discharge stability, and operating condition adaptability.

[0073] In step S400, the ignition drive and switching unit is controlled to perform an ignition test based on the operational readiness information. Synchronous acquisition commands are sent to the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit via the synchronization control unit. This is a crucial step in transforming the established and confirmed stable simulated operational condition into the actual ignition test process. Since the input power supply, output discharge, environmental disturbances, and ignition images of the ignition system all have significant transient characteristics, if each acquisition unit is started independently, inconsistencies can easily arise between the electrical signal sampling start point, the environmental parameter recording time, and the image acquisition frame sequence, thus affecting subsequent judgments on ignition effectiveness, discharge stability, and operational condition adaptability. Therefore, in this embodiment, after the current simulated operational condition meets the preset stability conditions, the detection devices are not manually started separately. Instead, the synchronization control unit, based on the operational readiness information and the ignition trigger parameters and data acquisition parameters in the current simulated operational condition stage, uniformly organizes ignition triggering, electrical parameter acquisition, environmental parameter acquisition, and high-speed ignition image acquisition, enabling various data to form a corresponding relationship around the same ignition action within the same test sequence.

[0074] In one alternative implementation, step S400 may include steps S410 to S470.

[0075] Step S410: Receive the operating condition readiness information and confirm that the current simulated operating condition allows entry into the ignition test state based on the operating condition readiness information.

[0076] The synchronization control unit can read the operating condition identifier, test phase identifier, stability judgment result and operating condition ready time identifier in the operating condition ready information to confirm that the current simulated operating condition has met the preset stability conditions.

[0077] If the stability determination result indicates that the current simulated operating condition is not ready, or the operating condition identifier is inconsistent with the simulated operating condition stage to be executed in the current operating condition test sequence, the synchronization control unit will not send an ignition trigger command to the ignition drive and switching unit, and will output an ignition test prohibition message.

[0078] This verification process ensures that ignition occurs only under simulated operating conditions where environmental stability has been verified, thus preventing mismatches between environmental conditions and test data.

[0079] Step S420: Configure the ignition drive and switching unit before ignition based on the ignition trigger parameters in the current simulation stage.

[0080] The ignition triggering parameters may include ignition triggering mode, ignition duration, number of ignitions, ignition interval time, and ignition channel information.

[0081] The ignition drive and switching unit determines the ignition device, ignition cable and ignition nozzle connection link corresponding to this test based on the ignition channel information, and determines whether to use single triggering, continuous triggering or cyclic triggering based on the ignition triggering method.

[0082] For situations requiring testing of multiple ignition nozzles or multiple ignition links, the ignition drive and switching unit can switch channels in the same simulated operating condition stage according to a preset channel sequence. However, each channel switch should correspond to an independent test stage identifier or sub-stage identifier so that subsequent data can be accurately attributed to the corresponding ignition link.

[0083] Step S430: Based on the data acquisition parameters in the current simulation stage, prepare the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit for data acquisition.

[0084] The electrical parameter acquisition unit prepares to acquire one or more data from input voltage, input current, output voltage, output current, and spark frequency based on the sampling channel, sampling frequency, sampling duration, and sampling start and end times.

[0085] The environmental parameter acquisition unit prepares to record the actual air pressure, actual temperature, and actual airflow state during the ignition test according to the sampling channel and recording period.

[0086] The high-speed ignition image acquisition unit prepares to acquire images of the ignition process of the ignition nozzle based on the image acquisition frame rate, image acquisition start time, image acquisition end time, and observation area information.

[0087] By completing the pre-acquisition preparation before ignition triggering, the problem of the acquisition unit not yet entering the working state after the ignition action has occurred can be avoided.

[0088] Step S440: The synchronization control unit generates a synchronization acquisition command and sends the synchronization acquisition command to the electrical parameter acquisition unit, the environmental parameter acquisition unit, and the high-speed ignition image acquisition unit.

[0089] The synchronization acquisition command carries an operating condition identifier, a test phase identifier, a synchronization time identifier, and acquisition start information. The synchronization time identifier is used to provide a common time reference for electrical parameters, environmental parameters, and ignition image data generated during the same test process.

[0090] Depending on the test equipment configuration, the synchronization time identifier can be generated by the software clock of the synchronization control unit, or by a unified trigger signal, hardware timing signal, or data acquisition card timestamp.

[0091] To ensure that the ignition transient process can be completely recorded, the synchronous acquisition command can enable the electrical parameter acquisition unit and the high-speed ignition image acquisition unit to enter the acquisition state before ignition triggering, and retain short-term data before ignition triggering, so as to facilitate subsequent analysis of the power supply status and environmental status before ignition.

[0092] Step S450: After the electrical parameter acquisition unit, environmental parameter acquisition unit and high-speed ignition image acquisition unit all report that the acquisition is ready, the synchronization control unit sends an ignition trigger command to the ignition drive and switching unit, so that the ignition drive and switching unit performs an ignition test on the ignition system under test according to the ignition trigger parameters.

[0093] During ignition testing, the ignition drive and switching unit provides test power to the ignition device and ensures the ignition device, ignition cable, and ignition nozzle are operational via a preset connection link. For a single ignition test, the ignition drive and switching unit performs one ignition action within one trigger cycle; for continuous ignition tests, the ignition drive and switching unit maintains ignition control for a preset ignition duration; for cyclic ignition tests, the ignition drive and switching unit repeatedly performs the ignition action according to a preset number of ignitions and ignition interval. By performing ignition triggering only after data acquisition is complete, the integrity of transient ignition data can be improved.

[0094] Step S460: During the ignition test, the electrical parameter acquisition unit, the environmental parameter acquisition unit, and the high-speed ignition image acquisition unit acquire corresponding data respectively, and bind the acquired data with the operating condition identifier, the test stage identifier, and the synchronization time identifier.

[0095] The electrical parameter acquisition unit collects at least one of the following: input voltage, input current, output voltage, output current, and spark frequency, to reflect the power supply status, output discharge status, and ignition frequency status of the ignition device. The environmental parameter acquisition unit collects actual air pressure, actual temperature, and actual airflow status to reflect whether the simulated working environment continuously meets the target simulated operating conditions during the ignition test.

[0096] The high-speed ignition image acquisition unit acquires images of the ignition process of the ignition nozzle, reflecting at least one of the following: ignition location, ignition duration, ignition brightness variation, and ignition intermittent state. Since the above data carries a synchronization time marker during acquisition, subsequent changes in output voltage, output current, environmental parameter fluctuations, and ignition image changes at a certain moment can be mapped to the same time location, thereby supporting correlation analysis of abnormal phenomena.

[0097] Step S470: After the ignition duration, sampling duration, or number of ignitions requirements are met, the synchronization control unit controls the ignition drive and switching unit to end the current ignition test, and controls each acquisition unit to end or maintain the corresponding acquisition process.

[0098] For test items that require recording the response status after ignition, the synchronous control unit can enable the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit to continue acquiring data for a preset holding time after ignition stops, so as to obtain the electrical signal attenuation status, environmental recovery status, and ignition termination image after ignition stops.

[0099] After the current ignition test is completed, the synchronization control unit can generate ignition execution completion information, which includes operating condition identifier, test stage identifier, ignition start time identifier, ignition end time identifier, data acquisition start time identifier, data acquisition end time identifier, and ignition execution status. This ignition execution completion information is used in subsequent step S500 to fragment and organize the multi-source data generated from this ignition test.

[0100] During the ignition test, the test system can also monitor the operating status of the ignition drive and switching unit, as well as each acquisition unit, in real time. When a power supply abnormality, output abnormality, acquisition channel abnormality, image acquisition abnormality, environmental parameter exceeding limits, or equipment protection status triggering is detected, the synchronization control unit can perform at least one of the following actions based on the abnormality type: stop ignition, pause acquisition, maintain environment, save acquired data, or enter a safety recovery process. The abnormality handling process can generate a corresponding abnormality process identifier and bind the abnormality process identifier with the operating condition identifier, test stage identifier, and synchronization time identifier. In this way, even if the current ignition test fails to complete, the electrical parameters, environmental parameters, and ignition image data before and after the abnormality can be retained, providing a basis for subsequent abnormality location and test verification.

[0101] Through step S400 above, this embodiment can achieve unified timing control of ignition triggering and multi-source data acquisition based on the current stable simulated operating conditions. Compared with the method of separately starting electrical parameter detection, environmental parameter recording, and image acquisition, this embodiment can make the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data all form a time correspondence around the same ignition action, thereby reducing data deviations caused by inconsistent triggering times. Subsequent step S500 can generate ignition system simulated working test data segments based on the operating condition identifier, test stage identifier, and synchronization time identifier. Steps S600 and S700 can further evaluate the ignition effectiveness, discharge stability, and operating condition adaptability of the ignition system under test based on the multi-source data in the same test segment.

[0102] In step S500, the acquired input electrical parameters, output electrical parameters, environmental parameters, and ignition image data are associated according to the operating condition identifier, test stage identifier, and synchronization time identifier. This process organizes the multi-source raw data generated in step S400 into a complete data unit under the same test object, the same simulated operating condition, and the same ignition timing. Since the data types, sampling frequencies, and data formats of the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit are not entirely the same—for example, voltage and current data are usually high-frequency time series, environmental parameters are usually relatively low-frequency state records, and ignition image data are usually continuous image frames or video clips—it is difficult to accurately determine whether a change in a discharge waveform corresponds to a change in the ignition image at the same moment, or whether an ignition anomaly occurs during the stable period of the target simulated operating condition, if the above data is not uniformly associated. This embodiment constructs a test data segment simulating the operation of an ignition system, which encapsulates the test object information, operating condition information, ignition execution information, electrical parameter data, environmental parameter data, and ignition image data in the same ignition test in a unified manner, thereby providing a structured data foundation for subsequent multi-source feature analysis and test evaluation.

[0103] In one alternative implementation, step S500 may include steps S510 to S570.

[0104] Step S510: Receive the multi-source acquisition data and ignition execution completion information corresponding to the current ignition test.

[0105] The multi-source acquired data includes input and output electrical parameters from the electrical parameter acquisition unit, environmental parameters from the environmental parameter acquisition unit, and ignition image data from the high-speed ignition image acquisition unit. The ignition execution completion information includes operating condition identifiers, test phase identifiers, ignition start time identifiers, ignition end time identifiers, acquisition start time identifiers, acquisition end time identifiers, and ignition execution status. The test system determines the data range requiring fragmentation based on the ignition execution completion information and uses this data range as the basis for subsequent data aggregation.

[0106] Step S520: Perform initial aggregation of the multi-source collected data according to the working condition identifier and the test phase identifier.

[0107] Specifically, the test system reads the operating condition identifier and test stage identifier carried by the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data, and groups data with consistent identifiers into the same candidate test data set.

[0108] For situations where multiple ignition actions or multiple ignition channels are tested sequentially within the same simulated operating condition, the test system can further combine the ignition start time identifier, ignition end time identifier, or ignition channel information to classify the data corresponding to different ignition actions into different candidate test data sets.

[0109] This processing method can prevent data from being mixed up under the same operating conditions due to different ignition cycles or different ignition links, ensuring that each test data segment has a clear data boundary.

[0110] Step S530: Perform time-series alignment of the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data in the candidate test data set according to the synchronization time identifier.

[0111] Specifically, the test system uses the synchronization time marker generated by the synchronization control unit as a common time reference, maps the input voltage, input current, output voltage, output current and spark frequency to the electrical parameter time axis, maps the actual air pressure, actual temperature and actual airflow state to the environmental parameter time axis, and maps the ignition image frame to the image time axis.

[0112] For data with different sampling frequencies, the testing system can retain their original sampling times and establish a time mapping relationship between different data, enabling the query of environmental parameters and ignition image frames within the corresponding or adjacent time range for any electrical parameter sampling time. This processing does not change the physical meaning of the original acquired data, but rather establishes a time-series correspondence between multi-source data for subsequent correlation analysis.

[0113] Step S540: Based on the acquisition start time identifier, ignition start time identifier, ignition end time identifier, and acquisition end time identifier, segment the time-aligned data.

[0114] The segmented data can retain at least the pre-acquisition data before ignition, the data during ignition execution, and the retained data after ignition. The pre-acquisition data before ignition is used to characterize the power supply and environmental conditions before ignition triggering; the data during ignition execution is used to characterize the main operating response of the ignition system; and the retained data after ignition is used to characterize the signal attenuation, environmental recovery, and ignition termination status after discharge termination.

[0115] By retaining the data within the aforementioned continuous time range, we can avoid losing the state changes before and after ignition by only capturing the instant the ignition action occurs, thereby improving the completeness of subsequent anomaly judgment.

[0116] Step S550: Perform integrity checks and validity marking on the multi-source data after fragment extraction.

[0117] The integrity check may include confirming whether the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data all have corresponding data records, confirming whether each data record carries the correct operating condition identifier, test phase identifier, and synchronization time identifier, and confirming whether the acquisition time range covers the ignition start time identifier and ignition end time identifier.

[0118] The validity marker is used to record whether the data is missing, delayed, sampled, has missing image frames, exceeds environmental parameter limits, or has abnormal acquisition channels. When a partial data loss is detected but the basic timing relationship of the test segment can still be preserved, the test system can mark the missing location and retain the existing data; when a critical data loss is detected that makes it impossible to determine the ignition test process, the test system can mark the test data segment as invalid or require retesting.

[0119] This processing method preserves the original test process without concealing data anomalies, preventing incomplete data from being mistakenly identified as normal test results in subsequent evaluation stages.

[0120] Step S560: Bind the test object information, target simulated working condition information, actual environmental parameters, ignition execution information and multi-source acquisition data to generate ignition system simulated working test data fragments.

[0121] The simulated working test data segment of the ignition system shall include at least the test object identifier, operating condition identifier, test stage identifier, synchronization time identifier, target air pressure, target temperature, target airflow state, actual air pressure, actual temperature, actual airflow state, ignition trigger parameters, input electrical parameters, output electrical parameters, spark frequency data, and ignition image data.

[0122] The test object identifier is used to identify the ignition device, ignition cable, and ignition nozzle corresponding to the test data segment. The target simulated operating condition information and actual environmental parameters are used to identify the environmental conditions corresponding to the test data segment. The ignition execution information is used to identify the execution status of the ignition action. The multi-source acquired data is used to characterize the actual response of the ignition system under test under the simulated operating condition.

[0123] Step S570: Generate segment identifiers and data indexes for the ignition system simulation test data segments.

[0124] The segment identifier can be formed by one or more combinations of test task identifier, test object identifier, operating condition identifier, test stage identifier, and ignition count information, and is used to uniquely identify the test data segment throughout the entire test task. The data index is used to record the location of electrical parameter data, environmental parameter data, and ignition image data in the storage unit, as well as the time mapping relationship between different data.

[0125] By generating segment identifiers and data indexes, the subsequent step S600 can quickly read the corresponding data when extracting the working response characteristics of the ignition system, and the step S800 can trace back to the original collected data when generating the test report.

[0126] After generating the simulated ignition system test data segments, the test system can store them in the data storage unit and return the segment identifier to the data processing and evaluation unit. For multi-condition continuous testing, the test system can generate multiple simulated ignition system test data segments according to the execution order of the test condition sequence, while maintaining the sequential relationship between the test data segments.

[0127] For multiple repeated ignition tests under the same simulated operating condition, the test system can associate multiple test data segments with the same operating condition identifier and distinguish different test segments by ignition count information or repeated test identifier.

[0128] This method allows for the analysis of not only single ignition test results but also the comparison of the stability of multiple ignitions under the same operating conditions and the response differences between different operating conditions.

[0129] Through the above step S500, this embodiment can unify the heterogeneous data generated by different acquisition units into ignition system simulation test data segments, so that each data segment has a clear test object, simulated working condition, ignition timing and data validity status.

[0130] This processing eliminates the need for subsequent steps (S600) to re-evaluate data sources and time boundaries. Instead, it allows for the direct extraction of power supply response features, discharge response features, spark frequency features, ignition image features, and environmental disturbance response features from the same test data segment. This reduces errors caused by offline comparison of multi-source data, improves the consistency and traceability of test data organization, and provides a reliable data foundation for subsequent automatic evaluation of the ignition system's ignition effectiveness, discharge stability, and operational adaptability.

[0131] In step S600, multi-source feature analysis is performed on the simulated working test data segment of the ignition system. This is a process of unified analysis of input electrical parameters, output electrical parameters, environmental parameters, and ignition image data under the same simulated working condition and ignition sequence, following the data association and fragmentation organization completed in step S500. Since the working response of the ignition system is not only manifested by a single parameter change—for example, normal input power supply does not necessarily indicate effective ignition of the ignition nozzle, the presence of high output voltage does not necessarily indicate a stable discharge process, and the appearance of bright spots in the ignition image requires consideration of output voltage, output current, and spark frequency to determine whether it corresponds to actual effective ignition—this embodiment uses multi-source feature analysis to extract power supply response features, discharge response features, spark frequency features, ignition image features, and environmental disturbance response features from the simulated working test data segment of the ignition system. This allows subsequent test evaluation to no longer rely on a single detection value or manual observation, but rather to make a comprehensive judgment based on multiple response features within the same test segment.

[0132] This processing method can more accurately reflect the complete working state of the ignition system under test under the current simulated operating conditions, and provide a characteristic basis for the subsequent step S700 to evaluate ignition effectiveness, discharge stability and operating condition adaptability.

[0133] In one alternative implementation, step S600 may include steps S610 to S670.

[0134] Step S610: Read the ignition system simulation test data segment and parse the data composition and validity markers therein.

[0135] The simulated ignition system test data segment includes at least the test object identifier, operating condition identifier, test stage identifier, synchronization time identifier, target simulated operating condition information, actual environmental parameters, ignition execution information, input electrical parameters, output electrical parameters, spark frequency data, and ignition image data. The data processing and evaluation unit first reads the corresponding data index based on the segment identifier, and then confirms whether the test data segment meets the feature parsing conditions based on the data validity marker. When the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data all have available records, the data processing and evaluation unit enters the multi-source feature parsing process; when a certain type of data has partial missing data but does not affect the basic timing relationship, the data processing and evaluation unit retains the missing data marker and continues to parse the available data; when the missing key data makes it impossible to determine whether the ignition action has occurred or the ignition process cannot be determined, the data processing and evaluation unit can mark the test data segment as having a limited feature parsing state and pass this state to subsequent evaluation steps.

[0136] Step S620: Extract power supply response features based on input electrical parameters. The input electrical parameters may include input voltage and input current, and the power supply response features are used to characterize the power supply status of the ignition device under the current simulated operating conditions and during the ignition triggering process.

[0137] Specifically, the data processing and evaluation unit can analyze the input voltage and current changes before ignition triggering, during ignition execution, and after ignition based on the ignition start time and ignition end time markers, respectively, and extract at least one feature from the following: input voltage stability, input current variation amplitude, input power supply establishment time, input power supply interruption status, and input power supply fluctuation status. For continuous ignition testing, the data processing and evaluation unit can also analyze whether the input voltage and current continuously decrease, periodically fluctuate, or abruptly change during continuous ignition to determine whether there are any abnormal power supply response characteristics on the power supply side of the ignition device that affect ignition stability. These power supply response characteristics can provide a basis for subsequently distinguishing between power supply abnormalities and discharge terminal abnormalities.

[0138] Step S630: Extract discharge response features based on output electrical parameters. The output electrical parameters may include output voltage and output current, and the discharge response features are used to characterize the response state of the ignition device when it outputs high-voltage discharge energy to the ignition nozzle via the ignition cable.

[0139] Specifically, the data processing and evaluation unit can identify the effective variation range of output voltage and output current during ignition execution, and extract at least one feature from the following: peak range of output voltage, peak range of output current, state of discharge pulse occurrence, duration of discharge, change of discharge interval, state of output waveform distortion, and state of output signal attenuation.

[0140] For test data where the spark discharge process varies periodically, the data processing and evaluation unit can identify the output response corresponding to each discharge event by combining the spark frequency data. For continuous ignition processes, the data processing and evaluation unit can analyze the output consistency between adjacent discharge events to reflect the discharge stability of the ignition system under continuous operating conditions.

[0141] By analyzing the discharge response characteristics, it can be determined whether the ignition system generates an output response corresponding to the ignition action, and this provides a basis for subsequent identification of unstable discharge, abnormal output, or abnormal ignition link.

[0142] Step S640: Extract spark frequency features based on spark frequency data. The spark frequency data can be obtained by the electrical parameter acquisition unit based on the output voltage signal, output current signal, or independent spark frequency detection signal.

[0143] The data processing and evaluation unit can correlate spark frequency data with ignition execution time intervals based on synchronization time identifiers, and extract at least one feature from the following: average spark frequency state, spark frequency fluctuation state, spark frequency interruption state, time interval between adjacent ignition events, and spark frequency change trend. For single ignition tests, spark frequency features can be used to determine whether a valid discharge event occurs after triggering; for continuous ignition tests, spark frequency features can be used to determine whether ignition events occur continuously according to the expected rhythm. By using spark frequency features, the output electrical response of the ignition system can be correlated with the actual ignition rhythm, avoiding the need to judge the effectiveness of ignition solely based on the output voltage or output current at a single moment.

[0144] Step S650: Extract ignition image features based on ignition image data. The ignition image data may be continuous image frames or video clips acquired by the high-speed ignition image acquisition unit, and the ignition image features are used to characterize the visualization state of the ignition process at the ignition nozzle.

[0145] The data processing and evaluation unit can determine the temporal position of each image frame during the ignition test based on the image acquisition start time, image acquisition end time, and synchronization time marker. Within a preset observation area, it can identify at least one feature from the following: ignition brightness change, ignition area location, ignition duration (frames), ignition intermittent state, ignition area offset state, and image missing state. The preset observation area can be determined based on the ignition nozzle installation position and the observation window position, used to limit the image analysis range and reduce the influence of environmental background or non-ignition areas on image judgment.

[0146] For continuous ignition testing, the data processing and evaluation unit can also statistically analyze the time relationship between the appearance and disappearance of the ignition region in continuous image frames to determine whether the ignition process is continuous, intermittent, or exhibits significant attenuation. By analyzing the ignition image features, it is possible to visually verify whether an ignition phenomenon corresponding to the ignition output occurs at the ignition nozzle.

[0147] Step S660: Extract environmental disturbance response features based on actual environmental parameters.

[0148] The actual environmental parameters include at least actual air pressure, actual temperature, and actual airflow state. The environmental disturbance response characteristics are used to characterize the maintenance state of the simulated operating conditions during the ignition test and the influence of environmental changes on the ignition response.

[0149] Specifically, the data processing and evaluation unit can analyze whether the actual air pressure, actual temperature, and actual airflow state remain within the allowable range corresponding to the target simulated operating condition within the time range corresponding to the ignition start time marker to the ignition end time marker, and extract at least one feature from the following: air pressure deviation state, temperature deviation state, airflow state change, duration of environmental fluctuations, and location of environmental exceedance time. When an ignition anomaly or output anomaly occurs, the data processing and evaluation unit can also query the changes in environmental parameters before and after the anomaly based on the synchronization time marker to determine whether the anomaly is temporally related to air pressure fluctuations, temperature fluctuations, or changes in airflow state. By using environmental disturbance response characteristics, anomalies caused by environmental instability or sudden environmental changes can be avoided from being misjudged as anomalies of the ignition system itself.

[0150] Step S670: The power supply response characteristics, discharge response characteristics, spark frequency characteristics, ignition image characteristics, and environmental disturbance response characteristics are uniformly characterized to generate the ignition system operating response characteristics.

[0151] The unified representation does not change the physical meaning of various features, but rather organizes features from different sources according to test object identifier, operating condition identifier, test stage identifier, and synchronization time identifier, so that various features can be mapped to the same test data segment and the same simulated operating condition stage. The ignition system operating response features can include the numerical results, status results, time location, and data validity status of various features.

[0152] By generating a unified ignition system operating response characteristic, subsequent steps S700 can directly compare this characteristic with the test criterion configuration information without having to reread and parse all the original data.

[0153] In a further embodiment, the data processing and evaluation unit can also associate and mark the correspondences between different types of features. For example, when the output voltage or output current shows a valid discharge response and an ignition region appears in the ignition image data within the corresponding synchronization time range, an electrical parameter image correspondence mark can be generated; when there is a significant change in the output electrical parameters but no valid ignition region is detected in the ignition image data, an output no-ignition correspondence mark can be generated; when an ignition intermittent occurs in the ignition image and the spark frequency data is interrupted within the same time range, an ignition interruption correspondence mark can be generated; when the actual air pressure, actual temperature, or actual airflow state simultaneously exceeds the limit when an ignition anomaly occurs, an environmental correlation anomaly mark can be generated. Through the above correlation marks, subsequent evaluation steps can not only determine whether there is an anomaly, but also further analyze whether the anomaly is more likely to originate from the power supply side, output side, ignition end, or environmental disturbance side.

[0154] During feature analysis, the data processing and evaluation unit can retain the mapping relationship between the original acquired data and the ignition system's operational response characteristics. In other words, each power supply response characteristic, discharge response characteristic, spark frequency characteristic, ignition image characteristic, and environmental disturbance response characteristic can be traced back to its corresponding original data time range, image frame range, or environmental parameter record range. By retaining this mapping relationship, testers can not only obtain automatic evaluation results when reviewing test reports later, but also revisit the original electrical parameter waveforms, environmental parameter records, and ignition image fragments based on anomaly characteristics, thereby improving the verifiability of test conclusions.

[0155] Through step S600, this embodiment can convert the ignition system simulation test data fragment formed in step S500 into ignition system operating response characteristics that can be directly used for evaluation. This processing retains the professional meaning of the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data, and establishes temporal correlations between multi-source features through synchronous time markers. Therefore, in the subsequent step S700, when evaluating ignition effectiveness, discharge stability, and operating condition adaptability, the power supply status, output discharge status, spark frequency status, ignition image status, and environmental holding status can be comprehensively considered, reducing misjudgments caused by judging a single parameter and improving the accuracy and reliability of the ignition system simulation test results.

[0156] In step S700, the ignition effectiveness, discharge stability and operating condition adaptability of the ignition system under test are evaluated based on the working response characteristics of the ignition system and the test criterion configuration information. This is the process of converting the multi-source response characteristics extracted in step S600 into test conclusions.

[0157] Since the evaluation object of the ignition system simulation test is not a single parameter of a single component, but the overall working response of the ignition device, ignition cable and ignition nozzle under the current air pressure, temperature and airflow conditions, this embodiment does not simply make a pass / fail judgment based on a certain voltage value, a certain current value or a certain frame of ignition image. Instead, it compares the power supply response characteristics, discharge response characteristics, spark frequency characteristics, ignition image characteristics and environmental disturbance response characteristics with the test criterion configuration information, and combines the temporal correlation between various characteristics to comprehensively determine whether the ignition system under test can stably and effectively complete ignition under the current simulated working conditions.

[0158] This evaluation method can reduce misjudgments caused by judging a single parameter and can output anomaly correlation information when anomalies occur, providing a basis for subsequent anomaly localization and test verification.

[0159] In one alternative implementation, step S700 may include steps S710 to S760.

[0160] Step S710: Read the ignition system working response characteristics and test criterion configuration information corresponding to the current test data segment, and establish the correspondence between the evaluation object and the evaluation criterion.

[0161] The ignition system's operational response characteristics include power supply response characteristics, discharge response characteristics, spark frequency characteristics, ignition image characteristics, and environmental disturbance response characteristics. The test criterion configuration information may include allowable input power supply range, allowable output voltage range, allowable output current range, allowable spark frequency range, ignition continuity requirements, ignition image validity requirements, environmental parameter stability requirements, and anomaly judgment rules. The data processing and evaluation unit determines the ignition device, ignition cable, and ignition nozzle corresponding to the current evaluation based on the test object identifier, operating condition identifier, and test stage identifier, and determines the criterion type to be used for the current evaluation based on the test item configuration information.

[0162] For test items that are not enabled in the test task, the corresponding criteria may not be included in the current evaluation, so as to avoid including uncollected items in the pass / fail judgment.

[0163] Step S720: Based on the power supply response characteristics and the allowable range of input power supply, determine whether the power supply status of the ignition system under test meets the test requirements under the current simulated operating conditions.

[0164] Specifically, the data processing and evaluation unit can compare the input voltage stability, input current variation, input power supply setup time, input power supply interruption status, and input power supply fluctuation status with the allowable range of input power supply in the test criterion configuration information. When the input voltage and input current are within the allowable range during ignition execution, and there are no continuous interruptions, obvious sudden changes, or excessive fluctuations, it can be determined that the power supply response meets the current test requirements.

[0165] When the input electrical parameters do not meet the corresponding criteria, a power supply anomaly state can be generated, and the synchronous time and location of the anomaly, the type of anomaly parameters, and the duration of the anomaly can be recorded. By conducting a preliminary evaluation of the power supply state, a basis can be provided for subsequent determination of whether discharge anomalies or ignition anomalies originate from the input power supply side.

[0166] Step S730: Based on the discharge response characteristics and spark frequency characteristics, determine whether the discharge stability of the ignition system under test meets the test requirements under the current simulated operating conditions.

[0167] Specifically, the data processing and evaluation unit can compare the output voltage peak range, output current peak range, discharge pulse occurrence status, discharge duration, discharge interval change, output waveform distortion status, output signal attenuation status, and spark frequency average status, spark frequency fluctuation status, and spark frequency interruption status with the output voltage allowable range, output current allowable range, and spark frequency allowable range in the test criterion configuration information.

[0168] When the output voltage, output current, and spark frequency can generate a discharge response that matches the ignition trigger parameters during ignition execution, and there are no abnormal intervals or frequency interruptions exceeding permissible limits between adjacent discharge events, the discharge stability can be determined to meet the current test requirements. When the output electrical parameters have effective output but the frequency fluctuates significantly, or when the output waveform exhibits abnormal distortion, abnormal discharge intervals, or missing output current, an unstable discharge state can be generated, and this state can be correlated with the corresponding synchronization time position.

[0169] This evaluation process provides a basis for judging the output capability of the ignition device and the transmission status of the ignition link.

[0170] Step S740: Based on the ignition image features and ignition image validity requirements, determine whether the ignition validity of the ignition system under test meets the test requirements under the current simulated operating conditions.

[0171] Specifically, the data processing and evaluation unit can analyze the changes in ignition brightness, the location of the ignition area, the number of frames of ignition duration, the ignition intermittent state, and the ignition area offset state within a preset observation area, and compare them with the ignition duration requirements and ignition image validity requirements in the test criterion configuration information.

[0172] When the ignition image data can identify an ignition region corresponding to the output discharge response within the ignition execution time range, and the ignition region is located within the preset observation area, and the ignition duration meets the requirements of the corresponding test item, the ignition validity can be determined to meet the current test requirements.

[0173] An abnormal ignition state can be generated when the output electrical parameters show a discharge response but no effective ignition area is detected in the ignition image, or when the ignition area deviates from the preset observation area, the ignition duration is insufficient, or there are abnormal intermittent periods in the ignition process.

[0174] This evaluation process avoids determining ignition effectiveness solely based on changes in electrical parameters, and also avoids ignoring the actual existence of discharge response based solely on changes in image brightness.

[0175] Step S750: Based on the environmental disturbance response characteristics and environmental parameter stability requirements, determine whether the current ignition test is within the effective simulated operating condition range, and determine the correlation between abnormal states and environmental changes.

[0176] Specifically, the data processing and evaluation unit can compare the actual air pressure, actual temperature and actual airflow state during ignition execution with the allowable ranges corresponding to the target air pressure, target temperature and target airflow state.

[0177] When the actual environmental parameters consistently meet the stability requirements during ignition execution, the simulated operating condition corresponding to the current test data can be deemed valid. When the actual air pressure, actual temperature, or actual airflow state exceeds limits, fluctuates, or becomes abnormal during ignition execution, an abnormal environmental condition can be generated, and the synchronous time and location of the environmental anomaly can be recorded.

[0178] Furthermore, if the time of ignition anomaly, unstable discharge, or spark frequency interruption coincides with or is adjacent to the time of environmental parameter exceeding limits, environmentally related anomaly information can be generated to characterize whether the current anomaly is related to changes in air pressure, temperature, or airflow disturbance. This process avoids directly attributing anomalies caused by unstable environments to the ignition system under test.

[0179] Step S760: Based on the comprehensive power supply status, discharge stability, ignition effectiveness, and operating condition adaptability, generate the current operating condition test evaluation results.

[0180] The current working condition test evaluation results include qualified status, abnormal status, and abnormal association information.

[0181] Specifically, when the power supply response, discharge stability, and ignition effectiveness meet the test requirements, and the current ignition test is within the effective simulated operating condition range, the data processing and evaluation unit can determine the current operating condition test evaluation result as qualified. When any evaluation item fails to meet the corresponding test criterion, the data processing and evaluation unit can determine the current operating condition test evaluation result as abnormal and generate abnormal correlation information based on the source of the abnormality.

[0182] The anomaly association information may include one or more of the following: power supply anomaly association information, discharge anomaly association information, ignition anomaly association information, environmental anomaly association information, and data validity anomaly information. The anomaly association information may also include the anomaly occurrence time, anomaly duration, the data channel involved in the anomaly, the original data index corresponding to the anomaly, and the test object identifier corresponding to the anomaly.

[0183] In a further embodiment, the current operating condition test evaluation results may also include anomaly priority or anomaly location direction. When the power supply response characteristics indicate that the input power supply does not meet the test requirements, and the discharge response characteristics and ignition image characteristics are both abnormal, the data processing and evaluation unit may prioritize pointing the anomaly location direction to the power supply side or the ignition drive side. When the input power supply meets the requirements, but the output voltage, output current, or spark frequency does not meet the requirements, the anomaly location direction may be pointed to the ignition device output side, the ignition cable transmission link, or the connection status.

[0184] When the output electrical parameters meet the requirements, but the ignition image does not show a valid ignition area, the abnormal positioning direction can be pointed to the discharge state of the ignition nozzle tip, the deviation of the observation area, or the working state of the ignition end. When both the output electrical parameters and the ignition image are abnormal, and the environmental parameters exceed the limits within the same time range, the abnormal positioning direction can be marked as being related to the disturbance of the simulated operating condition.

[0185] The above-mentioned abnormal location directions do not replace manual repair conclusions, but are output as test data analysis results to guide subsequent retesting, inspection, or repair troubleshooting.

[0186] In another optional implementation, for cases where multiple repeated ignition tests are performed under the same simulated operating condition, the data processing and evaluation unit can further statistically analyze the consistency of repeated tests based on the evaluation result of a single current operating condition test. Specifically, if multiple repeated ignitions all meet the test criteria, the repeated test result under the current simulated operating condition can be determined as stable and qualified; if some ignitions meet the test criteria but others exhibit ignition intermittent, discharge fluctuations, or environmental anomalies, the evaluation result under the current simulated operating condition can be determined as intermittent anomaly or insufficient stability, and the number and location of anomalies can be recorded. Through this processing, the reliability of the ignition system under continuous or repeated operating conditions can be evaluated more accurately, rather than making an overall qualified judgment based solely on a single successful ignition result.

[0187] During the evaluation process, the data processing and evaluation unit can retain the correspondence between test criteria, ignition system operating response characteristics, and the current operating condition test evaluation results. In other words, each qualified or abnormal state in the current operating condition test evaluation results can be traced back to specific criteria, response characteristics, and original data segments. By retaining this correspondence, when the subsequent step S800 generates the test report, it can output the basis for the test conclusions in the report, allowing test personnel to view the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data corresponding to a particular abnormal conclusion, thereby improving the interpretability and verifiability of the test results.

[0188] Through the aforementioned step S700, this embodiment can automatically evaluate the operating status of the ignition system under test under the current simulated operating conditions based on multi-source response characteristics and test criterion configuration information. This evaluation process considers both the power supply response, discharge response, spark frequency, and ignition image of the ignition system itself, as well as the stability of the simulated operating conditions during the ignition test. Therefore, it can comprehensively reflect the ignition effectiveness, discharge stability, and operating condition adaptability of the ignition system under the current pressure, temperature, and airflow conditions. This reduces the discrepancies in judgment caused by manual observation and offline comparison, improves the consistency of the ignition system simulation test conclusions, and provides a reliable single-condition evaluation basis for subsequently generating comprehensive ignition system simulation test results.

[0189] In step S800, based on the current operating condition test evaluation results corresponding to each simulated operating condition stage, a comprehensive test result for the ignition system simulation operation is generated, and a test report is output. This process summarizes, correlates, and solidifies the test evaluation results under a single or multiple operating conditions. Since ignition system simulation operation tests typically need to cover different air pressures, temperatures, and airflow states, passing a single simulated operating condition does not fully characterize the operational reliability of the ignition system under test across all target operating conditions. Therefore, in this embodiment, after completing the evaluation of each simulated operating condition stage, the test evaluation results of each current operating condition are integrated according to the execution order of the operating condition test sequence. Combined with test object information, operating condition test sequence, ignition system simulation operation test data fragments, and anomaly correlation information, a comprehensive test result reflecting the overall test status of the ignition system under test is generated.

[0190] This processing method allows test reports to not only include the final pass or fail conclusion, but also the process by which the conclusion was formed, the operating conditions under which the failure occurred, the corresponding data for the failure, and the suggested directions for review, thereby improving the traceability and engineering applicability of the test results.

[0191] In one alternative implementation, step S800 may include steps S810 to S860.

[0192] Step S810: Read the current working condition test evaluation results corresponding to each simulated working condition stage, and establish an evaluation result set according to the working condition test sequence.

[0193] The current operating condition test evaluation results include qualified status, abnormal status, and abnormal association information. The data processing and evaluation unit aggregates multiple current operating condition test evaluation results generated in the same test task into a single evaluation result set based on the operating condition identifier, test stage identifier, test object identifier, and segment identifier.

[0194] For scenarios involving multiple repeated ignition tests within the same simulated operating condition, the data processing and evaluation unit can aggregate the evaluation results of these repeated tests under the same operating condition identifier, retaining the ignition count information, synchronization time identifier, and data segment index corresponding to each ignition test. This aggregation method ensures that the comprehensive test results reflect both the state of a single ignition test and the consistency of repeated tests under the same simulated operating condition.

[0195] Step S820: Determine the stage test conclusions for each simulated working condition stage based on the evaluation result set.

[0196] Specifically, for a certain simulated operating condition stage, when the power supply status, discharge stability, ignition effectiveness, and operating condition adaptability under that simulated operating condition stage all meet the corresponding test criteria, the stage test conclusion of that simulated operating condition stage can be determined as a qualified operating condition.

[0197] When at least one of the following occurs during the simulated operating condition stage: power supply abnormality, unstable discharge, abnormal ignition, abnormal environmental conditions, or abnormal data validity, the stage test conclusion of the simulated operating condition stage can be determined as an operating condition abnormality, and the abnormality type, abnormality occurrence time, abnormality duration range, test objects involved in the abnormality, and the index of the data segment corresponding to the abnormality can be recorded.

[0198] For simulated operating condition phases where repeated ignition test results are inconsistent, the phase test conclusion for that phase can be determined as insufficient stability or intermittent anomaly, to distinguish it from situations where all ignition tests are abnormal. By forming phase test conclusions, a large number of individual evaluation results can be converted into test states directly corresponding to simulated operating conditions.

[0199] Step S830: Based on the phase test conclusions of each simulated working condition stage, generate the comprehensive test results of the ignition system simulation operation.

[0200] Specifically, when all simulated operating condition stages in the operating condition test sequence are qualified and there are no invalid data, test interruptions, or incomplete operating conditions, the comprehensive test result of the ignition system simulation operation can be determined as comprehensive qualified.

[0201] When any simulated operating condition stage has abnormal operating conditions, insufficient stability, invalid data, or incomplete testing, the comprehensive test result of the ignition system simulation operation can be determined as a comprehensive abnormality or a state requiring review, and a corresponding comprehensive abnormality description can be generated according to the abnormality type.

[0202] The comprehensive anomaly description may include the operating conditions under which the anomaly occurred, the corresponding ignition path, the response characteristics involved, the correlation between the anomaly and environmental disturbances, and the original data index corresponding to the anomaly. By generating comprehensive test results, an overall judgment can be formed among multiple simulated operating conditions, enabling testers to quickly understand whether the ignition system under test meets all the simulated operating conditions required for this test task.

[0203] Step S840: Summarize and analyze the anomaly correlation information to generate anomaly location information. The anomaly location information is used to help explain whether the anomaly is more likely to occur on the power supply side, output side, ignition cable transmission link, ignition nozzle firing end, simulated operating condition control side, or data acquisition side.

[0204] Specifically, when multiple abnormal operating conditions are accompanied by excessive input voltage or current, the abnormality location information can be pointed to the power supply side or the ignition drive side; when the input power supply meets the requirements but the output voltage, output current, or spark frequency is abnormal, the abnormality location information can be pointed to the output side of the ignition device, the ignition cable transmission link, or the connection status; when the output electrical parameters meet the requirements but the ignition image does not identify a valid ignition area, the abnormality location information can be pointed to the ignition nozzle ignition end, the installation location, or the observation area; when the time of the abnormality is related to the time when the actual air pressure, actual temperature, or actual airflow state exceeds the limit, the abnormality location information can be pointed to the abnormality related to the disturbance of the simulated operating condition; when the abnormality is mainly manifested as missing acquisition channels, missing image frames, or incomplete synchronization time markings, the abnormality location information can be pointed to the data acquisition side.

[0205] The anomaly location information is output as a test analysis result and is used for subsequent retesting, maintenance, or operational condition confirmation. It does not replace the final disassembly and inspection conclusion on the cause of failure of a specific component.

[0206] Step S850: Generate a test report based on the test object information, operating condition test sequence, ignition system simulation test data fragments, stage test conclusions, comprehensive test results of ignition system simulation, and anomaly location information.

[0207] The test report may include the test object information of the ignition system under test, test task information, target simulated operating condition information, operating condition test sequence, target environmental parameters and actual environmental parameters for each simulated operating condition stage, input electrical parameters, output electrical parameters, spark frequency data and ignition image data corresponding to each ignition test, evaluation results for each simulated operating condition stage, comprehensive test results, anomaly location information and corresponding test conclusions.

[0208] For raw electrical parameter waveforms and ignition image data with large volumes, the test report can record its data index, segment identifier, or storage path, and output key feature values, key image frames, or abnormal time ranges in the report, so that the complete raw data can be retrieved when needed. This report generation method can balance the readability of the report and the traceability of the raw data.

[0209] Step S860: Output and store the test report and its associated data.

[0210] The test report can be output through a display interface, stored as an electronic file in the data storage unit of the test system, and can also be generated as a printable or archived file according to the test task requirements. When storing the test report, the test system can simultaneously save the report number, test task identifier, test object identifier, test time, operator information, equipment status information, test data segment index, and report version information. For ignition systems under test that require subsequent retesting or comparative analysis, the test system can retrieve historical test reports based on the test object identifier and test task identifier and compare them with the new test results. By outputting and storing the test report, a complete record of this simulated work test can be created, meeting the traceability requirements in R&D verification, production inspection, and maintenance support scenarios.

[0211] In a further embodiment, step S800 can also generate retest recommendation information based on the comprehensive test results. When the comprehensive test results indicate an overall anomaly or a need for verification, the test system can provide suggested simulated operating condition stages for retesting, suggested ignition channels for retesting, suggested data channels to focus on, and suggested test objects to check, based on the anomaly occurrence conditions and anomaly location information. For example, when the anomaly only occurs under a specific air pressure or airflow condition, the retest recommendation information can point to the simulated operating condition stage corresponding to that target air pressure or airflow condition; when the anomaly only appears in the ignition nozzle or ignition link corresponding to a certain test object identifier, the retest recommendation information can point to that ignition link; when the anomaly and environmental parameters exceed limits simultaneously, the retest recommendation information can suggest first verifying the operating condition stability of the environmental simulation unit, and then re-executing the ignition test. By generating retest recommendation information, the targeting of anomaly verification can be improved, and the time consumption caused by repeatedly executing all operating conditions can be reduced.

[0212] In another optional implementation, the testing system can also generate a condition adaptability record based on the phase test conclusions of different simulated operating conditions. This condition adaptability record characterizes the test performance of the ignition system under test under different target gas pressures, target temperatures, and target airflow conditions. For example, the testing system can record under which simulated operating conditions the ignition system under test meets the test requirements, and under which simulated operating conditions it exhibits discharge instability, ignition intermittent periods, or abnormal environmental correlations. This condition adaptability record can be output along with the test report for subsequent analysis of the ignition system under test's adaptability to different simulated operating environments. Through this processing method, the test report not only provides a single pass / fail conclusion but also presents the differences in the ignition system's response to environmental changes.

[0213] During the test report generation process, the testing system maintains the correlation between the test report, the current operating condition test evaluation results, the ignition system's operational response characteristics, and the original test data. In other words, each stage of the test report, including test conclusions, comprehensive test results, and anomaly location information, can be traced back to the corresponding ignition system operational response characteristics, and further to input electrical parameters, output electrical parameters, environmental parameters, and ignition image data. By preserving this correlation, testers can directly locate the corresponding electrical parameter waveforms, environmental parameter records, and ignition image segments based on the anomaly time range in the report, thereby improving the verifiability of test conclusions and preventing test reports from simply outputting results without supporting data.

[0214] Through step S800 above, this embodiment can integrate the current operating condition test evaluation results formed under multiple simulated operating condition stages into a comprehensive test result for the ignition system simulation operation, and generate a test report containing test object information, operating condition test sequence, test data under each operating condition, evaluation results, anomaly location information, and test conclusions. This test report can fully reflect the operating performance of the ignition system under test under different gas pressure, temperature, and airflow conditions, enabling R&D personnel, inspection personnel, or maintenance personnel to view the test process, test conclusions, and anomaly evidence based on the same report. Therefore, it can improve the standardization, consistency, and traceability of the ignition system simulation operation test results, and provide data support for subsequent product improvement, quality inspection, and fault diagnosis.

[0215] This embodiment also provides an ignition system simulation test system, which is used to perform the ignition system simulation test method described in the above embodiment.

[0216] like Figure 2 As shown, the ignition system simulation test system includes an environmental simulation unit, an ignition drive and switching unit, a multi-source data acquisition unit, a synchronization control unit, and a data processing and evaluation unit.

[0217] The environmental simulation unit is used to establish the current simulated operating condition of the ignition system under test, and outputs the operating condition ready information after the current simulated operating condition meets the preset stability conditions.

[0219] The synchronization control unit is connected to the environmental simulation unit, the ignition drive and switching unit, and the multi-source data acquisition unit, respectively, and is used to coordinate the acquisition of the ignition test and the multi-source test data according to the operating condition readiness information.

[0220] The data processing and evaluation unit is connected to the synchronization control unit and the multi-source data acquisition unit, respectively, and is used to generate a working condition test sequence, perform correlation processing and feature analysis on the multi-source test data, and generate the current working condition test evaluation result.

[0221] In some embodiments, the multi-source data acquisition unit includes an electrical parameter acquisition unit, an environmental parameter acquisition unit, and a high-speed ignition image acquisition unit, all of which are connected to the synchronization control unit and the data processing and evaluation unit, respectively. The electrical parameter acquisition unit is used to acquire at least one of input voltage, input current, output voltage, output current, and spark frequency. The environmental parameter acquisition unit is used to acquire actual air pressure, actual temperature, and actual airflow conditions. The high-speed ignition image acquisition unit is used to acquire images of the ignition process of the ignition nozzle. By incorporating the electrical parameter acquisition unit, environmental parameter acquisition unit, and high-speed ignition image acquisition unit as specific components of the multi-source data acquisition unit, the system can simultaneously obtain electrical parameters, environmental parameters, and ignition image data under the same simulated operating conditions, thereby providing a data foundation for subsequent data correlation processing and ignition operating status evaluation.

[0222] In some embodiments, the environmental simulation unit includes a simulation space, a pressure regulation mechanism, a temperature regulation mechanism, and an airflow regulation mechanism. The simulation space accommodates at least some components of the ignition system under test. The pressure regulation mechanism regulates the air pressure within the simulation space or near the ignition nozzle. The temperature regulation mechanism regulates the temperature within the simulation space or in the area where the component under test is located. The airflow regulation mechanism regulates the airflow interruption, flow rate, velocity, or direction near the ignition nozzle. The environmental simulation unit establishes the current simulation condition based on the environmental setup command sent by the synchronization control unit and can perform closed-loop adjustment based on the actual environmental parameters fed back by the environmental parameter acquisition unit. Through this structure, the environmental simulation unit can place the ignition system under test in a simulated working environment corresponding to the target air pressure, target temperature, and target airflow state, and output condition readiness information to the synchronization control unit after the current simulation condition meets preset stability conditions.

[0223] In some embodiments, the ignition drive and switching unit includes a test power supply interface, an ignition trigger control module, and an ignition channel switching module. The test power supply interface provides test power to the ignition system under test. The ignition trigger control module controls the ignition action based on the ignition duration, number of ignitions, and ignition interval. The ignition channel switching module selects the corresponding ignition link during multi-station or multi-channel testing, enabling the ignition device, ignition cable, and ignition nozzle to complete the ignition test according to the test task requirements.

The electrical parameter acquisition unit can also obtain spark frequency data based on the output voltage signal or output current signal. By acquiring the electrical parameters on the input and output sides, basic data can be provided for extracting power supply response characteristics, discharge response characteristics, and spark frequency characteristics.

[0225] In some embodiments, the environmental parameter acquisition unit includes a pressure detection device, a temperature detection device, and an airflow detection device. The pressure detection device is used to acquire actual air pressure, the temperature detection device is used to acquire actual temperature, and the airflow detection device is used to acquire actual airflow conditions. The environmental parameter acquisition unit sends the acquired actual environmental parameters to a synchronization control unit and a data processing and evaluation unit, enabling the synchronization control unit to determine whether the current simulation condition meets preset stability conditions, and enabling the data processing and evaluation unit to extract environmental disturbance response characteristics based on the actual environmental parameters.

[0226] In some embodiments, the high-speed ignition image acquisition unit includes a high-speed camera, an observation window, and an image buffer module. The high-speed camera is positioned facing the ignition area of ​​the ignition nozzle through the observation window, and is used to acquire continuous image frames or video clips of the ignition process. The image buffer module is used to temporarily store image data before ignition triggering, during ignition execution, and after ignition, for use by the data processing and evaluation unit to extract ignition image features. The high-speed ignition image acquisition unit can record at least one of the following: ignition position of the ignition nozzle, ignition duration, ignition brightness change, and ignition intermittent state, providing image evidence for ignition effectiveness evaluation.

[0227] In some embodiments, the synchronization control unit is used to generate a synchronization acquisition command and an ignition trigger command. The synchronization acquisition command carries an operating condition identifier, a test phase identifier, and a synchronization time identifier. The multi-source data acquisition unit acquires data according to the synchronization acquisition command and binds the acquired multi-source test data with the operating condition identifier, test phase identifier, and synchronization time identifier. When the multi-source data acquisition unit includes an electrical parameter acquisition unit, an environmental parameter acquisition unit, and a high-speed ignition image acquisition unit, the electrical parameter acquisition unit, the environmental parameter acquisition unit, and the high-speed ignition image acquisition unit acquire electrical parameters, environmental parameters, and ignition images respectively according to the synchronization acquisition command. After confirming that the current simulated operating condition meets the preset stability conditions and that the multi-source data acquisition unit is in the acquisition ready state, the synchronization control unit sends an ignition trigger command to the ignition drive and switching unit, thereby coordinating the timing of environment establishment, ignition triggering, and multi-source test data acquisition.

[0228] In some embodiments, the data processing and evaluation unit includes a task parsing module, a working condition sequence generation module, a data fragment generation module, a feature parsing module, and an evaluation module.

The working condition sequence generation module is used to generate a working condition test sequence based on the ignition system simulation working test task. The data fragment generation module is used to correlate and process the multi-source test data collected by the multi-source data acquisition unit according to the working condition identifier, test stage identifier, and synchronization time identifier to generate ignition system simulation working test data fragments. The feature parsing module is used to extract ignition system working response features based on the ignition system simulation working test data fragments. The evaluation module is used to generate a current working condition test evaluation result based on the ignition system working response features and the test criterion configuration information.

[0229] In some embodiments, when the multi-source test data includes input electrical parameters, output electrical parameters, environmental parameters, and ignition image data, the data segment generation module is used to associate the input electrical parameters, output electrical parameters, environmental parameters, and ignition image data according to the operating condition identifier, test stage identifier, and synchronization time identifier to generate ignition system simulated operating test data segments. The feature parsing module is used to extract power supply response features, discharge response features, spark frequency features, ignition image features, and environmental disturbance response features. The evaluation module is used to compare the ignition system operating response features with the test criterion configuration information to obtain the current operating condition test evaluation result. Through the above processing, the data processing and evaluation unit can unify data from different acquisition sources under the same simulated operating condition and the same test sequence for evaluation, thereby improving the accuracy and traceability of the test evaluation results.

[0230] In some embodiments, the ignition system simulation test system further includes a test report generation unit. The test report generation unit is connected to the data processing and evaluation unit and is used to generate a comprehensive test result for the ignition system simulation based on the current operating condition test evaluation results corresponding to each simulation operating condition stage, and output a test report.

The anomaly location information in the test report can be associated with the corresponding operating condition identifier, test stage identifier, synchronization time identifier, and original data index to facilitate the verification of abnormal test results.

[0231] It should be noted that, in order to simplify the description of this invention and thus aid in the understanding of one or more embodiments, the foregoing description of the embodiments of this invention may sometimes combine multiple features into a single embodiment, drawing, or description thereof.
