Description

Technical Field

[0001] The invention relates to the technical field of multi-channel controlled variable frequency power supply control, and in particular to a balanced control method and system for testing a multi-channel controlled variable frequency power supply. Background Art

[0002] Multi-channel controlled variable frequency power supplies are widely used in the testing process of electronic equipment. Their main function is to allocate power between multiple test channels to meet the testing requirements of different devices. In modern test systems, with the diversification of devices under test and the complexity of test requirements, higher requirements are placed on the dynamic regulation capability of power supplies. However, the existing multi-channel controlled variable frequency power supplies still have some technical bottlenecks in resource allocation. Especially in the face of complex scenarios where multiple devices are tested at the same time, how to efficiently allocate limited power resources to ensure the smooth progress of the test of each device has become a key issue.

[0003] Traditional power control methods are usually based on preset fixed allocation strategies and are slow to respond to dynamically changing test requirements. This method can meet the requirements when testing a single device or when resources are sufficient, but when multiple devices are tested simultaneously and the power supply capacity is limited, it is easy for some devices to not obtain enough power, thereby affecting the accuracy of the test results and increasing the test waiting time. Especially when multiple channels need to work together, if the output power of each channel cannot be properly regulated, it may not only cause power overload, but also cause test failure or equipment damage.

[0004] Therefore, how to better improve resource allocation and dynamic control capabilities during testing is an issue that needs to be addressed urgently. Summary of the invention

[0005] The present invention overcomes the defects of the prior art and provides a balanced control method and system for testing a multi-channel controlled variable frequency power supply, the important purpose of which is to improve the resource allocation and dynamic control capabilities during testing.

[0006] To achieve the above-mentioned purpose, the first aspect of the present invention provides a balanced control method for testing a multi-channel controlled variable frequency power supply, comprising:

[0007] Monitor the real-time operation status of the target multi-channel controlled variable frequency power supply, analyze the real-time channel usage status of the target multi-channel controlled variable frequency power supply, and obtain channel usage status analysis information;

[0008] Acquire test requirement information, analyze the matching channel of the next test device in combination with the channel usage status analysis information, and determine whether the remaining output capacity of the target multi-channel controlled variable frequency test power supply is adapted to the test requirement of the next test device;

[0009] If the remaining output capacity of the target multi-channel controlled variable frequency power supply cannot support the current test requirements, the test rules of the real-time test equipment and the expected test process of the equipment to be tested are analyzed to obtain the regular feature information of the real-time test equipment and the expected test process division information;

[0010] A balanced control optimization model is constructed, and a test balanced control scheme for the device to be tested is formulated based on the regular characteristic information of the real-time test equipment and the expected test process division information, so as to control the target multi-channel controlled variable frequency power supply.

[0011] In this solution, the real-time operation status of the target multi-channel controlled variable frequency power supply is monitored, the real-time channel usage status of the target multi-channel controlled variable frequency power supply is analyzed, and the channel usage status analysis information is obtained, which specifically includes:

[0012] A sensor array is set for a target multi-channel controlled variable frequency power supply, and the output voltage of the target multi-channel controlled variable frequency power supply in real time is obtained based on the sensor array to form a voltage timing sequence;

[0013] Preset a channel enable judgment threshold, judge the voltage timing sequence with the channel enable judgment threshold, obtain an output voltage greater than the channel enable judgment threshold according to the judgment result, and calculate a deviation value from the channel enable judgment threshold;

[0014] Sorting the deviation values ​​to obtain the output voltage with the smallest deviation value, defining the corresponding detection time node as the channel enable point, and obtaining the output voltage sequence after the channel enable point;

[0015] Perform feature extraction on the acquired output voltage sequence, extract the output voltage features of the target multi-channel controlled variable frequency power supply after the channel enable point, and analyze the output voltage change by combining the Kalman filter algorithm;

[0016] The extracted output voltage features are input into the Kalman filter for initialization, the output voltage corresponding to the channel enabling point is used as the initial state estimation value and the covariance matrix is ​​initialized to predict the voltage state at the next moment, and the predicted output voltage value is generated;

[0017] A preset error threshold is used to calculate the error between the predicted output voltage value and the actual output voltage value, and the error is compared with the error threshold. When the error value is less than the error threshold, the actual output voltage value at the time node corresponding to the target predicted output voltage value is the channel stable point.

[0018] Based on the time node corresponding to the channel steady point, the operation monitoring data of the target multi-channel controlled variable frequency power supply is obtained to calculate the operation power consumption and obtain the operation power consumption analysis information; the channel usage status analysis information of the target multi-channel controlled variable frequency power supply is generated by combining the operation power consumption analysis information and the operation monitoring data.

[0019] In this solution, the acquisition of test requirement information, analysis of the matching channel of the next test device in combination with the channel usage status analysis information, and determination of whether the remaining output capacity of the target multi-channel controlled variable frequency test power supply is adapted to the test requirement of the next test device specifically include:

[0023] If there is a matching idle channel, analyze whether the remaining output capacity of the target multi-channel controlled variable frequency power supply can support the test requirements of the next test equipment, and obtain the output capacity information of the target multi-channel controlled variable frequency power supply;

[0024] Calculate the output capacity information of the target multi-channel controlled variable frequency power supply and the channel usage status analysis information to obtain the remaining output capacity information of the target multi-channel controlled variable frequency power supply, and compare and judge with the test demand characteristic peak value;

[0025] If the remaining output capacity information is greater than the test requirement characteristic peak value, it means that the current test requirement can be met, and the test control parameters of the next test device are generated by combining the matching idle channels and the test requirement characteristic information to form a test control solution for recommendation;

[0026] If the remaining output capacity information is less than the test demand peak value, it means that the remaining output capacity of the target multi-channel controlled variable frequency power supply cannot support the current test demand.

[0027] In this solution, if the remaining output capacity of the target multi-channel controlled variable frequency power supply cannot support the current test requirements, the test rules of the real-time test equipment and the expected test process of the device to be tested are analyzed, specifically including:

[0028] Acquire test requirement information of a real-time test device, perform feature extraction on the test requirement information of the real-time test device, extract the requirement features of the real-time test device to obtain the requirement feature information of the real-time test device;

[0029] According to the real-time test equipment demand characteristics, a test demand curve of each test equipment using the target multi-channel controlled variable frequency power supply is formed at the current moment;

[0030] Extract features from the test demand curve of each test device, extract the real-time test regularity features of each test device, and obtain regularity feature information of the real-time test device;

[0031] Acquire test requirement characteristic information of the device to be tested, construct an expected test process of the device to be tested according to the test requirement characteristic information of the device to be tested, and obtain expected test process information;

[0032] According to the expected test process information, the expected test process of the device to be tested is divided into a number of sub-processes in combination with the test parameter requirement characteristics and the corresponding test requirement time of the device to be tested, and the expected test process division information is obtained.

[0033] In this solution, the construction of the balanced control optimization model formulates a test balanced control scheme for the device to be tested based on the regular feature information of the real-time test equipment and the expected test process division information, specifically including:

[0034] Building a balanced control optimization model based on the GA algorithm, obtaining regular feature information of real-time test equipment and expected test process division information, and inputting them into the balanced control optimization model for analysis;

[0035] The optimization goal is set according to the input expected test process division information, and each sub-test process is sorted based on the time attribute of the expected test process to form an expected test timeline;

[0036] Based on the expected test time axis, the test requirement characteristics corresponding to each test phase are obtained, and the power resource change status of each channel in the corresponding test phase is calculated using the regular characteristic information of the real-time test equipment, and the population is initialized to obtain the initial population;

[0037] Preset the objective function and constraint conditions, calculate the individual fitness in the initial population according to the objective function, and make a judgment with the preset threshold, and perform selection, mutation and crossover operations according to the judgment result to obtain the initial solution;

[0038] Introducing a taboo search algorithm, taking the initial solution as the input of the taboo search algorithm, initializing parameters and setting a taboo table, generating neighborhood solutions based on neighborhood movement rules, selecting the optimal solution based on the generated neighborhood solutions and obtaining the corresponding fitness value and neighborhood movement, and updating the taboo table;

[0039] If the current optimal solution exists in the taboo table, skip the current optimal solution and select the next optimal solution, perform iterative search and update the taboo table to obtain the optimized individuals after the search, update the population, perform iterative optimization based on the updated population, and output the optimal solution;

[0040] The target multi-channel controlled variable frequency power supply control schemes for each test phase are formed based on the optimal solution of the output, and then merged to form a test balance control scheme for the device to be tested, and the target multi-channel controlled variable frequency power supply is controlled.

[0041] In this solution, the test balancing control scheme for the device to be tested is formulated based on the regular feature information of the real-time test device and the expected test process division information, and further includes:

[0042] If the allocatable resources of the target multi-channel controlled variable frequency power supply cannot support the test requirements of the current test phase of the device under test during the time period of a test phase of the device under test, then analyze whether the test phases of the device under test can be sequentially exchanged;

[0043] If the sequence cannot be changed, the current test phase will be postponed to the next time period to analyze whether the allocatable resources in the next time period are suitable.

[0044] If the sequence can be changed, analyze whether the allocatable resources in other test phases are compatible with the current time period;

[0045] If it is compatible, the adaptation test phase and the current test phase are swapped. If it is not compatible, the current test phase is postponed to the next time period to determine whether it is compatible.

[0057] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0059] Figure 1 A flow chart of a balanced control method for testing a multi-channel controlled variable frequency power supply provided by an embodiment of the present invention;

[0060] like Figure 1 As shown, the present invention provides a flow chart of a balanced control method for testing a multi-channel controlled variable frequency power supply, including:

[0061] S102, monitoring the real-time operation status of the target multi-channel controlled variable frequency power supply, analyzing the real-time channel usage status of the target multi-channel controlled variable frequency power supply, and obtaining channel usage status analysis information;

[0062] S104, acquiring test requirement information, analyzing the matching channel of the next test device in combination with the channel usage status analysis information, and determining whether the remaining output capacity of the target multi-channel controlled variable frequency test power supply is adapted to the test requirement of the next test device;

[0063] S106, if the remaining output capacity of the target multi-channel controlled variable frequency power supply cannot support the current test requirements, the test rules of the real-time test equipment and the expected test process of the equipment to be tested are analyzed to obtain the regularity feature information of the real-time test equipment and the expected test process division information;

[0064] S108, constructing a balanced control optimization model, formulating a test balanced control scheme for the device to be tested based on the regular feature information of the real-time test device and the expected test process division information, and controlling the target multi-channel controlled variable frequency power supply.

[0065] It should be noted that the present invention provides a balanced control method and system for testing a multi-channel controlled variable frequency power supply. First, the real-time operating status of the target multi-channel controlled variable frequency power supply is monitored and the usage of its real-time channels is analyzed. Then, the test requirement information of the next test device is obtained, and combined with the analysis information of the channel usage status, it is determined which channel is suitable for the connection of the next test device. At the same time, it is further analyzed whether the remaining output capacity of the target multi-channel controlled variable frequency power supply can meet the test requirements of this new device. If the remaining output capacity is sufficient, the device will be tested smoothly. In the case where the remaining output capacity cannot support the current test requirements, the test rules of the device currently being tested and the expected test process of the device to be tested are further analyzed. Based on the GA algorithm, a balanced control optimization model is constructed, and the test requirement characteristics of the real-time test device and the expected process of the device to be tested are considered to formulate the optimal test balanced control scheme. The output of each channel is dynamically adjusted by the change of real-time power demand to ensure that the device to be tested can also complete the test smoothly under the condition of limited resources. A more efficient power utilization rate and a more stable test environment are achieved, thereby improving the reliability and accuracy of the overall test process.

[0066] Further, in a preferred embodiment of the present invention, the real-time operation status of the target multi-channel controlled variable frequency power supply is monitored, and the real-time channel usage status of the target multi-channel controlled variable frequency power supply is analyzed to obtain the channel usage status analysis information, which specifically includes:

[0067] A sensor array is set for a target multi-channel controlled variable frequency power supply, and the output voltage of the target multi-channel controlled variable frequency power supply in real time is obtained based on the sensor array to form a voltage timing sequence;

[0068] Preset a channel enable judgment threshold, judge the voltage timing sequence with the channel enable judgment threshold, obtain an output voltage greater than the channel enable judgment threshold according to the judgment result, and calculate a deviation value from the channel enable judgment threshold;

[0069] Sorting the deviation values ​​to obtain the output voltage with the smallest deviation value, defining the corresponding detection time node as the channel enable point, and obtaining the output voltage sequence after the channel enable point;

[0070] Perform feature extraction on the acquired output voltage sequence, extract the output voltage features of the target multi-channel controlled variable frequency power supply after the channel enable point, and analyze the output voltage change by combining the Kalman filter algorithm;

[0071] The extracted output voltage features are input into the Kalman filter for initialization, the output voltage corresponding to the channel enabling point is used as the initial state estimation value and the covariance matrix is ​​initialized to predict the voltage state at the next moment, and the predicted output voltage value is generated;

[0072] A preset error threshold is used to calculate the error between the predicted output voltage value and the actual output voltage value, and the error is compared with the error threshold. When the error value is less than the error threshold, the actual output voltage value at the time node corresponding to the target predicted output voltage value is the channel stable point.

[0073] Based on the time node corresponding to the channel steady point, the operation monitoring data of the target multi-channel controlled variable frequency power supply is obtained to calculate the operation power consumption and obtain the operation power consumption analysis information; the channel usage status analysis information of the target multi-channel controlled variable frequency power supply is generated by combining the operation power consumption analysis information and the operation monitoring data.

[0074] It should be noted that a sensor array is set on the target multi-channel controlled variable frequency power supply to obtain the output voltage of the power supply when it is running in real time, and to form a voltage timing sequence. In order to judge the enabling state of the channel, a channel enabling judgment threshold is preset, the obtained voltage timing sequence is compared with the threshold, and the output voltage value greater than the threshold is screened out according to the comparison result. At the same time, the deviation between these output voltage values ​​and the channel enabling judgment threshold is calculated, and they are sorted according to the deviation value to obtain the output voltage value with the smallest deviation value. The corresponding detection time node is defined as the channel enabling point, and the output voltage sequence after the channel enabling point is obtained. Next, the obtained output voltage sequence is feature extracted, and the changes of these voltage features are further analyzed in combination with the Kalman filter algorithm. The extracted voltage features are input into the Kalman filter for initialization, and the output voltage corresponding to the channel enabling point is used as the initial state estimation value, and the covariance matrix is ​​initialized at the same time to predict the voltage state at the next moment, thereby generating a predicted output voltage value. An error threshold is preset, the predicted output voltage value is compared with the actually measured output voltage value, the error is calculated, and it is compared with the error threshold. When the error value is less than the preset error threshold, the actual output voltage value at that moment can be considered as the stable point of the channel. Based on the time node corresponding to the stable point, the operation monitoring data of the target multi-channel controlled variable frequency power supply is obtained, and the operation power consumption is calculated to obtain the corresponding power consumption analysis information. Finally, these operation power consumption analysis information are combined with the operation monitoring data to generate the channel usage status analysis information of the target multi-channel controlled variable frequency power supply, thereby providing a basis for further regulation and optimization.

[0075] Further, in a preferred embodiment of the present invention, the acquisition of test requirement information, analyzing the matching channel of the next test device in combination with the channel usage status analysis information, and determining whether the remaining output capacity of the target multi-channel controlled variable frequency test power supply is adapted to the test requirement of the next test device, specifically includes:

[0076] Acquire test requirement information, generate a test requirement curve corresponding to the next test device according to the test requirement information, extract test requirement power characteristics, test requirement frequency and test requirement time characteristics based on the test curve, and obtain test requirement characteristic information;

[0077] Acquire channel usage status analysis information, acquire unenabled channels of the target multi-channel controlled variable frequency power supply according to the channel usage status analysis information, and acquire channel capability information corresponding to the unenabled channels;

[0078] Extract the test requirement characteristic peak value of the next test device based on the test requirement characteristic information, perform matching analysis with the channel capability information corresponding to the unenabled channel, and determine whether the idle channel of the target multi-channel controlled variable frequency power supply matches the corresponding test requirement;

[0079] If there is a matching idle channel, analyze whether the remaining output capacity of the target multi-channel controlled variable frequency power supply can support the test requirements of the next test equipment, and obtain the output capacity information of the target multi-channel controlled variable frequency power supply;

[0080] Calculate the output capacity information of the target multi-channel controlled variable frequency power supply and the channel usage status analysis information to obtain the remaining output capacity information of the target multi-channel controlled variable frequency power supply, and compare and judge with the test demand characteristic peak value;

[0081] If the remaining output capacity information is greater than the test requirement characteristic peak value, it means that the current test requirement can be met, and the test control parameters of the next test device are generated by combining the matching idle channels and the test requirement characteristic information to form a test control solution for recommendation;

[0082] If the remaining output capacity information is less than the test demand peak value, it means that the remaining output capacity of the target multi-channel controlled variable frequency power supply cannot support the current test demand.

[0083] It should be noted that when the target multi-channel controlled variable frequency power supply is used to test the next test equipment, based on the real-time channel usage status, it is analyzed whether the test requirements of the device to be tested can be met. First, the test requirement information of the next test equipment is obtained, and a test requirement curve is generated. By analyzing the test requirement curve, the power characteristics of the test requirements, the frequency characteristics of the test requirements, and the time characteristics of the test requirements are extracted. Next, the analysis information of the channel usage status is obtained, the unenabled channels in the target multi-channel controlled variable frequency power supply are identified, and the channel capacity information of these unenabled channels is further obtained. This information includes the maximum power output capacity, frequency range, and supportable time period of each unenabled channel. Then, the extracted test requirement feature information is matched and analyzed with the channel capacity information of the unenabled channels to determine whether these idle channels can meet the requirements of the next test equipment. If the matching analysis results show that there are idle channels that meet the requirements, the overall remaining output capacity of the target multi-channel controlled variable frequency power supply is further analyzed to determine whether it is sufficient to support the test requirements of the next test equipment. By performing comprehensive calculations on the output capacity information of the target multi-channel controlled variable frequency power supply and the channel usage status analysis information, the remaining output capacity information of the power supply is obtained and compared with the characteristic peak value of the test requirement. If the remaining output capacity information is greater than the characteristic peak value of the test requirement, this means that the current power supply output capacity can meet the requirements of the next test device. In this case, the test control parameters of the next test device are generated in combination with the matching idle channel information and the test requirement characteristic information, and a test control scheme is constructed based on this for recommendation. If the remaining output capacity information is less than the test requirement peak value, this means that the remaining capacity of the target multi-channel controlled variable frequency power supply is insufficient to support the current test requirements. In this case, the test control scheme under the existing conditions cannot be recommended, so the power resource balancing control scheme is further analyzed.

[0084] Further, in a preferred embodiment of the present invention, if the remaining output capacity of the target multi-channel controlled variable frequency power supply cannot support the current test requirements, the test rules of the real-time test equipment and the expected test process of the device to be tested are analyzed, specifically including:

[0085] Acquire test requirement information of a real-time test device, perform feature extraction on the test requirement information of the real-time test device, extract the requirement features of the real-time test device to obtain the requirement feature information of the real-time test device;

[0086] According to the real-time test equipment demand characteristics, a test demand curve of each test equipment using the target multi-channel controlled variable frequency power supply is formed at the current moment;

[0087] Extract features from the test demand curve of each test device, extract the real-time test regularity features of each test device, and obtain regularity feature information of the real-time test device;

[0088] Acquire test requirement characteristic information of the device to be tested, construct an expected test process of the device to be tested according to the test requirement characteristic information of the device to be tested, and obtain expected test process information;

[0089] According to the expected test process information, the expected test process of the device to be tested is divided into a number of sub-processes in combination with the test parameter requirement characteristics and the corresponding test requirement time of the device to be tested, and the expected test process division information is obtained.

[0090] It should be noted that when judging whether the device to be tested can be tested using the current multi-channel controlled variable frequency power supply, first, it is judged whether the device to be tested can be connected to the current power supply, because even if the current power supply has spare channels, the channel load may not be able to bear the test requirements of the device to be tested. At the same time, it is judged whether the remaining output capacity of the power supply can meet the test requirements. If not, consider resource allocation and formulate a balanced control plan to control the target power supply to complete the test requirements support for the device to be tested. The basis of the balanced control plan is formulated based on the test demand curve of the real-time test equipment and the expected test process of the device to be tested, because there may be a situation where the real-time test equipment of the target power supply corresponds to the test demand change, that is, the demand is the largest load in a certain period of time, but only the general channel load is required in a certain period of time. At this time, the remaining load corresponding to the time period is the available load, so that the device to be tested can be tested. By analyzing the test demand curve of the real-time test equipment, the test regularity characteristics of the corresponding real-time test equipment are further obtained. Then, based on the test demand characteristics of the equipment to be tested, the expected test process of the equipment to be tested is obtained, that is, the test parameters such as channel load required for the equipment to be tested and the duration of the corresponding parameters, which provides a basis for subsequent balanced regulation and optimization.

[0091] Further, in a preferred embodiment of the present invention, the construction of the balanced control optimization model formulates a test balanced control scheme for the device to be tested based on the regular feature information of the real-time test device and the expected test process division information, specifically including:

[0092] Building a balanced control optimization model based on the GA algorithm, obtaining regular feature information of real-time test equipment and expected test process division information, and inputting them into the balanced control optimization model for analysis;

[0093] The optimization goal is set according to the input expected test process division information, and each sub-test process is sorted based on the time attribute of the expected test process to form an expected test timeline;

[0094] Based on the expected test time axis, the test requirement characteristics corresponding to each test phase are obtained, and the power resource change status of each channel in the corresponding test phase is calculated using the regular characteristic information of the real-time test equipment, and the population is initialized to obtain the initial population;

[0095] Preset the objective function and constraint conditions, calculate the individual fitness in the initial population according to the objective function, and make a judgment with the preset threshold, and perform selection, mutation and crossover operations according to the judgment result to obtain the initial solution;

[0096] Introducing a taboo search algorithm, taking the initial solution as the input of the taboo search algorithm, initializing parameters and setting a taboo table, generating neighborhood solutions based on neighborhood movement rules, selecting the optimal solution based on the generated neighborhood solutions and obtaining the corresponding fitness value and neighborhood movement, and updating the taboo table;

[0097] If the current optimal solution exists in the taboo table, skip the current optimal solution and select the next optimal solution, perform iterative search and update the taboo table to obtain the optimized individuals after the search, update the population, perform iterative optimization based on the updated population, and output the optimal solution;

[0098] The target multi-channel controlled variable frequency power supply control schemes for each test phase are formed based on the optimal solution of the output, and then merged to form a test balance control scheme for the device to be tested, and the target multi-channel controlled variable frequency power supply is controlled.

[0099] It should be noted that a balanced control optimization model is constructed using a genetic algorithm (GA), and the regular feature information of real-time test equipment and the expected test process division information are input into the balanced control optimization model for analysis. Based on the input expected test process division information, optimization goals are set, such as resource utilization, etc., and each sub-test process is sorted according to the time attribute to form an expected test timeline. The expected test timeline contains the time period intervals required for each test stage when the device to be tested is tested.

[0100] Next, the test requirement characteristics corresponding to each test phase are obtained based on the expected test time axis, including power requirements, frequency requirements, and time requirements. The regular feature information of the real-time test equipment is used to calculate the changes in the power resources of each channel in each test phase of the device to be tested. The population is initialized based on this information to obtain the initial population. The objective function and related constraints are preset, and the fitness of each individual in the initial population is calculated according to the objective function. The fitness value is compared with the preset threshold, and selection, mutation, and crossover operations are performed according to the comparison result to obtain the initial solution. Then, the taboo search algorithm (TS) is introduced to take the initial solution as the input of the taboo search algorithm, start parameter initialization and set the taboo table. The essence of the taboo search algorithm is to realize global search and local search through the taboo table, realize the global search that jumps out of the local optimality, find a better solution, and thus reduce the limitations of the genetic algorithm. Based on the neighborhood movement rule, the neighborhood solution is generated, and the optimal solution is selected from it, the corresponding fitness value and neighborhood movement are obtained, and the taboo table is updated accordingly. If the current optimal solution already exists in the taboo table, skip the optimal solution and select the next optimal solution instead, continue the iterative search, and continuously update the taboo table. Through multiple iterative optimizations, an optimized individual is finally obtained to update the population. Finally, based on the output optimal solution, the target multi-channel control variable frequency power supply control scheme for each test stage is obtained and integrated to form a test balance control scheme for the device to be tested. Then, the power output of each channel is dynamically adjusted to optimize resource allocation, ensuring that each device can successfully complete the test task in a complex test environment and effectively improving the overall efficiency and reliability of the system.

[0101] Furthermore, in a preferred embodiment of the present invention, the method of formulating a test balancing control scheme for the device to be tested based on the regular feature information of the real-time test device and the expected test process division information further includes:

[0102] If the allocatable resources of the target multi-channel controlled variable frequency power supply cannot support the test requirements of the current test phase of the device under test during the time period of a test phase of the device under test, then analyze whether the test phases of the device under test can be sequentially exchanged;

[0103] If the sequence cannot be changed, the current test phase will be postponed to the next time period to analyze whether the allocatable resources in the next time period are suitable.

[0104] If the sequence can be changed, analyze whether the allocatable resources in other test phases are compatible with the current time period;

[0105] If it is compatible, the adaptation test phase and the current test phase are swapped. If it is not compatible, the current test phase is postponed to the next time period to determine whether it is compatible.

[0106] It should be noted that, in the process of balanced regulation and optimization, there is a situation where the allocatable resources of the target multi-channel controlled variable frequency power supply in a certain time period cannot support the test requirements of the current test phase of the device to be tested. The allocatable resources are the sum of the power resource surplus generated by the change in the test requirements of each channel and the remaining output capacity of the target multi-channel controlled variable frequency power supply. When the above situation occurs, it is necessary to determine whether the various test phases of the device to be tested can be sequentially exchanged. If the sequence can be exchanged, analyze whether the allocatable resources of other test phases and the current time period are compatible. If they are compatible, the adapted test phase is exchanged with the current test phase. If not, the current test phase is postponed to the next time period to determine whether it is compatible. If the sequence cannot be exchanged, the current test phase is postponed to the next time period, and the allocatable resources of the next time period are analyzed to determine whether they are compatible, until there is a time period that can be adapted, thereby ensuring the integrity and rationality of the test of the device to be tested. Further use of the allocatable resources of the power supply can avoid the situation where the test equipment cannot be tested in time due to insufficient resources, and reduce the test waiting time.

[0107] Figure 2 A test resource allocation and control flow chart for a multi-channel controlled variable frequency power supply test provided by an embodiment of the present invention;

[0108] like Figure 2 As shown, the present invention provides a test resource allocation and control flow chart for multi-channel control variable frequency power supply testing, including:

[0109] S202, monitoring the target multi-channel controlled variable frequency power supply, analyzing the real-time channel usage status of the target multi-channel controlled variable frequency power supply, and obtaining channel usage status analysis information;

[0110] S204, acquiring test requirement information, determining whether there is a matching channel for the device to be tested in combination with the channel usage status analysis information, and analyzing whether the remaining output capacity can match the test requirement of the device to be tested;

[0111] S206, if the test requirements are not matched, the test rules of the real-time test equipment and the expected test flow of the device to be tested are analyzed, and the results are input into the balance control optimization model to formulate a test balance control plan for the device to be tested;

[0112] S208, controlling the target multi-channel controlled variable frequency power supply according to the test balancing control scheme of the device to be tested, and performing test resource allocation control.

[0113] In addition, the balanced control method for testing a multi-channel controlled variable frequency power supply provided by the present invention further includes the following steps:

[0114] Perform channel operation monitoring on the target multi-channel controlled variable frequency power supply to obtain real-time channel operation monitoring information, and perform data preprocessing on the real-time channel operation monitoring information to obtain preprocessing result information;

[0115] According to the preprocessing result information, a real-time operation monitoring sequence of each operation channel is formed, and anomaly detection is performed on the real-time operation data of each operation channel based on an isolation forest algorithm to obtain anomaly detection information;

[0116] Extract features from the abnormality detection information to obtain abnormal operation features, use the Markov algorithm to predict the next state, calculate the state transition probability of the abnormal operation features, predict the next abnormal state according to the state transition probability, and obtain abnormal state prediction information;

[0117] Based on the abnormal state prediction information, the operation fluctuation risk of the target operation channel at a future moment is evaluated, and if there is an operation fluctuation risk, power output resource compensation is performed on the target operation channel;

[0118] Preset the power output resource redundancy, obtain the test demand curve of the target operation channel, extract the normal operation benchmark when the abnormality occurs in combination with the abnormality detection information, and calculate the deviation between the normal operation benchmark and the abnormal operation data;

[0119] A power output resource compensation plan is formulated based on the calculated deviation value combined with the preset power output resource redundancy to compensate the target operating channel.

[0120] It should be noted that when the target multi-channel controlled variable frequency power supply is in use, there are various factors that cause operation fluctuations when each channel supports the corresponding test equipment test. If it is a normal fluctuation, no adjustment is required. If it is a risk fluctuation, adjustment is required to further improve the resource allocation level of the target operation channel to ensure the stable operation of the channel. By setting the power output resource redundancy, not only the power output stability can be improved, but also the power supply usage limit can be avoided. If the power supply is in an extreme usage state for a long time, it may bring the risk of abnormal power supply operation, further reducing the service life and safety of the power supply.
