[0022] In the current field of aviation power supply testing, particularly in 70V boost curve control, traditional control algorithms and test equipment suffer from significant design deficiencies and technical bottlenecks. These issues primarily manifest in insufficient load control density and accuracy, inadequate algorithm design, a high number of manually operated boost devices, and significant human intervention. This leads to inaccurate boost control logic, insufficient control precision, and insufficient stability, resulting in high failure rates and a significant impact on the lifespan of aviation power supplies. Furthermore, insufficient automation imposes significant costs on testing efficiency and production output. These issues not only impact the accuracy and consistency of test data but also pose potential risks to the reliability, safety, and service life of aviation power supply systems.

[0023] In response to the problems existing in the above-mentioned related technologies, this embodiment provides a boost control system and method based on a segmented algorithm.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a boost control system based on a segmented algorithm, including: The segmented boost module is used to execute the segmented boost strategy to obtain the output voltage for boost control. The segmented boost module is also used to correct the output voltage using the boost compensation voltage.

[0025] Specifically, the output voltage includes: , , in, is the output voltage, is the impedance coefficient of the cable in the power supply at the current time point, is the impedance coefficient of the cables in the wiring cabinet at the current time point, is the load impedance coefficient at the current time point, is the current load point control coefficient, is the current current value, N is the total number of time points in the time series, n is the current sequence number, Usmp is the voltage obtained by collecting the voltage through the instrument, and Iload is the current load current to be loaded, which is extracted from the gear value.

[0026] The staged boost strategy divides the boost process into three intervals and implements corresponding boost control strategies for each stage, thereby achieving refined and dynamic regulation and control of the output voltage. In actual operation, factors such as line losses, temperature drift, and sudden load changes may cause the output voltage to deviate from the expected value. A boost compensation voltage can be introduced to correct the output voltage. Substituting the boost compensation voltage as Usmp into the above formula for correction, the final corrected output voltage is obtained.

[0027] The load monitoring module is used to obtain the load change rate by real-time monitoring of the segmented boost module. If the load change rate is greater than the voltage compensation threshold, a boost compensation start signal is generated and sent to the boost compensation module.

[0028] Specifically, the segmented boost module is typically also connected to a load, providing a test voltage to the load via its output voltage. The load change rate refers to the rate of change of the load current or power per unit time, typically expressed as the current change per unit time or the power change per unit time. High-precision current sensors (such as Hall sensors, shunts, and current transformers) are used to monitor the segmented boost module in real time to obtain the real-time waveform of the load current. The analog current signal is converted into a digital signal to obtain the load change rate. Alternatively, a differential algorithm or sliding window method is used to calculate the current change and its rate of change between the current moment and the previous moment to obtain the load change rate. When the detected load change rate exceeds the voltage compensation threshold, for example, 10% / s, the boost compensation module is triggered.

[0029] The boost compensation module includes a collaborative voltage compensation unit, a voltage drop loss compensation unit and a secondary compensation unit. The boost compensation module is used to obtain a boost compensation voltage through the collaborative voltage compensation unit and / or the voltage drop loss compensation unit and / or the secondary voltage compensation unit after receiving a boost compensation start signal.

[0030] Specifically, the boost compensation module consists of three key subunits: the collaborative voltage compensation unit, the voltage drop compensation unit, and the secondary voltage compensation unit. Each unit performs different compensation tasks and can operate independently or in conjunction with the system state. The collaborative voltage compensation unit is used to compensate for power output changes caused by ambient temperature changes, the voltage drop compensation unit is used to compensate for cable losses caused by cable heating, and the secondary voltage compensation unit is used to compare the voltage corresponding to the current time point with the standard value and compensate for voltages that exceed a preset error.

[0031] In some more specific embodiments, a boost control system based on a segmented algorithm is applied to aviation power supply test equipment. The object to be tested can be an aviation power supply vehicle. The boost control system acts as a power supply function in the system circuit, is electrically connected to the load control cabinet through the wiring cabinet power supply, and is electrically connected to the test bench through the control cabinet power supply. The load output is controlled by the console algorithm, and the output voltage of the aviation power supply test equipment is controlled by the boost control system, thereby achieving the purpose of automatic boost control.

[0032] Aviation power supply test equipment tests power supply parameter performance by applying voltage to the power supply.

[0033] In this embodiment, a segmented boost strategy is implemented through a segmented boost module, automatically controlling the boost process and ensuring consistency. The segmented boost module is monitored in real time, and the boost compensation module is automatically triggered when the load change rate is excessive. A boost compensation voltage is generated by coordinating the voltage compensation unit and / or the voltage drop loss compensation unit and / or the secondary voltage compensation unit. This boost compensation voltage is used to correct the output voltage, providing voltage compensation based on specific conditions, thereby improving boost control accuracy and avoiding rapid voltage increases.

[0034] Optionally, the boost compensation voltage includes a temperature compensation voltage, a loss compensation voltage, and a secondary compensation voltage. The boost compensation voltage is obtained by coordinating a voltage compensation unit and / or a voltage drop loss compensation unit and / or a secondary voltage compensation unit, including: If the current temperature value is within the preset temperature compensation range, a temperature compensation voltage is obtained according to the coordinated voltage compensation unit; If the current voltage value is less than the preset voltage compensation value, and the current current value is greater than the preset current compensation value, a loss compensation voltage is obtained according to the voltage drop loss compensation unit; If the current boost error is greater than the preset error compensation range, a secondary compensation voltage is obtained according to the secondary voltage compensation unit.

[0035] In some more specific embodiments, changes in ambient temperature can affect power output changes. The current temperature value is acquired through a temperature acquisition device. If the current temperature value is below 0° or above 40°, a temperature compensation voltage is generated by the coordinated voltage compensation unit. The current voltage and current values ​​are detected in real time. When the current voltage value is below 20V and the current current value is above 50A, the cable heats up due to the increased current, and a significant amount of energy is consumed through cable losses. In this case, voltage compensation is required by the voltage drop loss compensation unit. Therefore, if the current voltage value is less than 20V and the current current value is greater than 50A, a loss compensation voltage is generated by the voltage drop loss compensation unit. If the current boost error is greater than ±0.5V (the current boost error represents the difference between the current voltage and the corresponding preset standard value during a preset time), a secondary compensation voltage is generated by the secondary voltage compensation unit. This error band is adjusted based on sample and customer requirements. The error voltage is based on the boost voltage and test product specifications. The segmented boost voltage has a resolution greater than 1V, and the error range should vary within the 1V error band to ensure the accuracy of the boost algorithm. At the same time, the nameplate of the sample being tested has specific specification requirements, and the error band is usually within the range of 1%-10%.

[0036] In this optional embodiment, by introducing the triple trigger conditions of temperature, voltage and error, different compensation units are called respectively, and the collaborative voltage compensation unit, voltage drop loss compensation unit and secondary voltage compensation unit are used to achieve fine control of the output voltage during the boost process.

[0037] Optionally, obtaining the temperature compensation voltage according to the coordinated voltage compensation unit includes: Inputting temperature compensation parameters and synergistic compensation parameters into the synergistic compensation model to obtain an initial temperature deviation voltage, wherein the temperature compensation parameters include temperature, load output power, and vibration acceleration; Among them, the initial temperature deviation voltage includes: , in, is the initial temperature deviation voltage, T is the temperature, P is the load output power, a is the vibration acceleration, k is the coordinated compensation parameter, is the last temperature compensation voltage; Inputting the temperature compensation parameters into the pre-trained neural network compensation model to obtain the predicted compensation parameters; Inputting the temperature compensation parameter and the predicted compensation parameter into the collaborative compensation model to obtain the predicted temperature deviation voltage; The temperature compensation voltage is obtained according to the sum of the initial temperature deviation voltage and the predicted temperature deviation voltage.

[0038] Specifically, the device type of the device under test is obtained, and the corresponding collaborative compensation parameters obtained by the device type, and the initial temperature deviation voltage include: , , in, is the initial temperature deviation voltage, T is the temperature, P is the load output power, a is the vibration acceleration, k is the coordinated compensation parameter, =The last temperature compensation voltage. Changes in ambient temperature T affect power output, which is acquired through a temperature acquisition instrument. P is the load output power, calculated as P = Iout * Uout. The output voltage and current are acquired through instrumentation. a is the current load vibration acceleration, typically in the range of 0-1, with coefficients varying depending on the load hardware. k is the synergistic compensation parameter, a constant system with different coefficients for different sensors, typically between 0.97-1.03, with an initial value of 1. It is the voltage deviation of the previous compensation. The default value is 1 for the first compensation. If it is greater than the first value, it is the voltage deviation after the previous calculation.

[0039] In some more specific embodiments, the synergistic compensation model is used to calculate , and the input parameters and the calculated initial temperature deviation voltage Stored in the database, the first compensation K is a constant coefficient of 1 and is directly stored in the database after calculation. When it is greater than the first time, the compensation coefficient K is brought into the collaborative compensation model after calculation and storage, and then calculated. The predicted compensation parameter k=Min(Kn) / N. Take the minimum value of K from the N record libraries, and calculate the coefficient K through the formula. Among them, Kn is the coefficient K after each calculation, and the current calculation is that Kn is the coefficient distribution set of all K from the previous time. When the number of knowledge bases is larger, N is larger. At this time, K is infinitely close to 0, and the voltage resolution to be compensated is higher. Input the temperature compensation parameters and the predicted compensation parameters into the collaborative compensation model to obtain the predicted temperature deviation voltage, and take the sum of the initial temperature deviation voltage and the predicted temperature deviation voltage of the two as the temperature compensation voltage. The more data, the higher the compensation voltage resolution, and thus the higher the accuracy to be achieved. For example =1, the predicted temperature deviation voltage may be 0.01 after compensation for the first time, 0.009 for the second time, and 0.008 for the third time. The accuracy is improved by multiple compensation resolutions.

[0040] In this optional embodiment, algorithm data is supplemented to establish a model database, data is learned and trained through a neural network, and compensation elements and features are learned. During the timing of the curve boosting process, when affected by external influences such as the environment and cable loss, compensation is automatically detected and controlled, and the boosting process is supplemented and fine-tuned according to the above-mentioned compensation algorithm formula to meet the boosting accuracy and timing requirements.

[0041] Optionally, obtaining the loss compensation voltage according to the voltage drop loss compensation unit includes: Performing voltage compensation by a given voltage according to the voltage drop loss compensation unit to obtain a loss compensation voltage; Among them, the loss compensation voltage includes: , in, is the loss compensation voltage, For a given voltage, is the impedance coefficient of the cables in the wiring cabinet at the current time, and I is the current current value.

[0042] Specifically, The impedance of the cable is different. The impedance of cables of different specifications is different. It can be obtained by the cable specifications. Align the compensation and set the given voltage to an artificially set value to meet the voltage drop caused by large current loss during the boost process.

[0043] Optionally, obtaining the secondary compensation voltage according to the secondary voltage compensation unit includes: obtaining a secondary compensation voltage according to a secondary voltage compensation unit; Among them, the secondary compensation voltage includes: , in, is the secondary compensation voltage, is the impedance coefficient of the cable in the power supply at the current time point, is the load impedance coefficient at the current time point, and I is the current current value.

[0044] Optionally, executing a segmented boost strategy to obtain an output voltage for boost control includes: The load impedance coefficient is obtained through the segmented boost strategy; The output voltage is obtained according to the load impedance coefficient to perform boost control; Among them, the output voltage includes: , in, is the output voltage, is the impedance coefficient of the cable in the power supply at the current time point, is the impedance coefficient of the cables in the wiring cabinet at the current time point, is the load impedance coefficient at the current time point, is the current load point control coefficient, is the current current value, N is the total number of time series, and n is the current series number.

[0045] In some more specific embodiments, the boost load is a resistive load with a power requirement of 40kW. The internal impedance of the distribution wiring cabinet is required to be 0.516mΩ. The cable length is required to be 16m, and the cable impedance is required to be 3.296mΩ. The boost load current range is 7: 25A, 50A, 100A, 200A, 400A, 850A, and 740A, respectively. The boost voltage starts at 1.5V and is linearly applied over time.

[0046] Optionally, the segmented boost strategy includes a constant current boost strategy, a constant current voltage limiting strategy, and a constant voltage current limiting strategy. The load impedance coefficient is obtained by the segmented boost strategy, including: If the current voltage value is less than or equal to the first voltage threshold, the load impedance coefficient is obtained by executing a constant current boost strategy; If the current voltage value is greater than the first voltage threshold and less than or equal to the second voltage threshold, the load impedance coefficient is obtained by executing the constant current and voltage limiting strategy; If the current voltage value is greater than the second voltage threshold and less than or equal to the third voltage threshold, the load impedance coefficient is obtained by executing the constant voltage and current limiting strategy.

[0047] Specifically, the constant current boost strategy is used to indicate a strategy applied to a voltage of 0-48V, a current of 5A±0.1A, and a boost slope of 5V / s; the constant current limiting strategy is used to indicate a strategy applied to a voltage of 49-56V, a current of 1A±0.01A, and a boost slope of 1V / s; the constant voltage limiting strategy is used to indicate a strategy applied to a voltage of 57-70V, a current of 10A, and a boost slope of 1V / s.

[0048] In some more specific embodiments, the load impedance coefficient is obtained by executing the constant current boost strategy, including: 12s boost to 48V, starting from the first 1.5V boost loading and counting for 12s, if it does not reach 5V within 5s, it is considered a boost failure. The load is divided into 7 gears, the gear 1 resistance coefficient R1 = Usmp / Iload1, the resistance coefficient refers to the load impedance coefficient at the current time point, the gear 2 resistance coefficient R2 = Usmp / Iload2, the gear 3 resistance coefficient R3 = Usmp / Iload3, the gear 4 resistance coefficient R4 = Usmp / Iload4, the gear 5 resistance coefficient R5 = Usmp / Iload5, the gear 6 resistance coefficient R6 = Usmp / Iload6, the gear 7 resistance coefficient R7 = Usmp / Iload7. Usmp is obtained by collecting voltage through an instrument, and Iload is the load current to be loaded, which is extracted from the gear value. It takes 12s to boost the voltage to 48V. According to the above formula, the linear order starting from 4 is the even voltage 6, 8, 10, 12, 14, 16...48V. The theoretical time interval for each sequence is 500ms. According to the maximum execution time of the program is 100ms, the execution interval of each point is 400ms. In this way, the voltage boost of 24 voltage points is completed in 12s, and the total time is 24×500=12000ms, that is, 12s.

[0049] The load impedance coefficient obtained by implementing the constant current and voltage limiting strategy includes: 8s boost to 56V, starting from the first boost loading at 49V for 8s. The load range is still 7 gears, except that the coefficients for gears 3, 5, and 7 are 1. The remaining load coefficients remain the same as in the first stage. The load coefficient refers to the load impedance coefficient at the current time. The boost calculation is calculated by substituting the parameters according to Formula 1. The boost voltage includes 5 points: 49, 51, 53, 55, and 56V. The switching is performed every 1.6s, and the total time is 1600×5=8000ms, which is 8s.

[0050] By implementing the constant voltage and current limiting strategy, the load impedance coefficient is obtained: 8.5s boost to 70V, starting from the first 57V boost loading time of 8.5s. The load range is the same as 7 gears, except that gears 1, 2, 6, and 7 have a coefficient of 1. Gears 3, 4, and 5 are R3 = (Usmp / Iload2) / 2, R4 = R3 / 2, and R5 = R4 / 2, respectively. The boost calculation is based on formula 1, substituting the parameters. The boost voltage includes 17 points: 57, 58, 50, 60, 61, 62, 63, 64, 65, 66, 67, 67.5, 68, 68.5, 69, 69.5, and 79V. Switching is done every 500ms, for a total time of 500 × 17 = 8500ms, or 8.5s.

[0051] Optionally, the pre-trained neural network compensation model construction process includes: Obtain a historical training set, the historical training set including historical temperature compensation parameters and historical prediction compensation parameters; Train the initial neural network model according to the historical training set to obtain a trained neural network model; The model accuracy of the trained neural network model is tested. When the model accuracy does not meet the model accuracy requirements, more historical training sets of data are obtained for retraining until the model accuracy requirements are met, and a pre-trained neural network compensation model is obtained.

[0052] Optionally, a data analysis module is further included, which includes a data processing unit and a data reporting unit. The data processing unit is used to normalize the data, and the data reporting unit is used to generate a boosting process curve by monitoring the boosting process.

[0053] Specifically, the data processing unit analyzes, processes, and statistically displays test data.

Test data is stored in MySQL and can be queried and exported as CSV files. The software interface allows for histogram analysis and comparison of multiple test data. The data is normalized and encoded in UTF-8. Yield and defective rate data can be compared and statistically analyzed. Defective rate data displays the causes of defects, and individual test data can be displayed as pie charts showing the percentage of yield and defective rates. Data filtering is available to filter out and discard test data. The filtering algorithm extracts the minimum and maximum limits of specifications from the database, discarding data that falls outside these limits. Data query and extraction are supported, allowing data to be queried by DUT SN, test results (yield or defective rate), tester, and test time. Query data can be exported as CSV files.
