Description

Technical Field

[0001] This application relates to the technical field of integrated verification test of aircraft power supply systems, and particularly to a method for accurately mapping electrical interfaces of an integrated verification test system for aircraft power supply systems. Background Art

[0002] In cross-tests of virtual-real integration in various fields, the main method for mapping and interacting simulation data of virtual models and physical data of physical tests is to configure sensors to dynamically collect status information and periodically read data, and perform data interaction between the physical field and the virtual field through manual configuration and fixed network protocol transmission.

[0003] The disclosed patents and literature mainly describe the construction methods of virtual-real data interaction paths and channels. Some patents mention the basic steps of mapping interaction, including node status mapping, data acquisition and transmission, data processing and analysis, and optimization decision feedback. Data preprocessing includes data cleaning, data type conversion, and format conversion. In the virtual field, simulation and simulation of the preprocessed data are performed, including threshold adjustment, operation setting, etc., and analysis and error reporting are performed based on the processing results. However, the disclosed patents and literature do not fully consider the characteristics of electrical interfaces and do not disclose the specific mapping methods of electrical interfaces in virtual-real integration and verification.

[0004] Currently, in the physical test system of an aircraft power supply system, the basic block diagram of a typical technical method for virtual-real mapping of electrical interfaces is as Figure 1 shown. The electrical simulation data of the virtual model running in the digital simulation system needs to interact with the electrical interfaces of the physical test system through various IO boards, signal conditioning boxes, power drive devices, exciters, and measurement and control devices. However, the aircraft power supply system has its particularities. It not only has multiple voltage levels such as 115VAC, 230VAC, 28VDC, 270VDC, 540VDC, etc., but also has different power supply systems such as variable-frequency AC, constant-frequency AC, high-voltage DC, and low-voltage DC mixed to supply power to the electrical loads of the whole aircraft. The electrical interface signals of the aircraft power supply system are numerous and have complex characteristics. Therefore, the power drive devices, signal conditioning boxes, exciters, and measurement and control devices supporting different physical tests of aircraft power supply systems are basically non-standard devices, and the degree of equipment customization is very high. The accuracy differences between different electrical interface channels are large and the consistency is not high. If directly Figure 2 performing electrical interface mapping and virtual-real signal interaction according to the shown method, the mapping accuracy is low, and in the case of long-term operation, the data difference degree between the power supply system model simulation and the physical test will rapidly accumulate and spread, making the model operation state unable to match the physical part, resulting in the failure of the physical test system of the aircraft power supply system. Summary of the Invention

[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0020] Existing technologies do not fully consider the characteristics of electrical interfaces and do not differentiate the virtual-physical mapping methods for electrical interfaces from those for other types of interfaces. Furthermore, the electrical interfaces and test equipment in aircraft power supply systems have unique characteristics. Using existing technologies will result in low mapping accuracy of electrical interfaces in virtual-physical fusion tests of aircraft power supply systems, leading to a continuous increase in data errors between the virtual and physical systems, affecting the validity of the virtual-physical fusion cross-validation results, and causing the failure of the physical test system of the aircraft power supply system.

[0021] The precise mapping method for electrical interfaces proposed in this application is specifically designed to map the characteristics of electrical interfaces, such as voltage values, current values, signal timing, signal frequency, and transient characteristic matching, under normal and abnormal operating scenarios of aircraft power supply systems, and discloses the specific operation method.

[0022] This application aims to provide a method for accurate mapping of electrical interfaces in an integrated verification test system for aircraft power supply systems, thereby improving the electrical characteristic integrity, matching accuracy, and compatibility of the electrical interfaces between virtual verification tests and physical verification tests, and enhancing the effectiveness of the results of the physical test system for aircraft power supply systems.

[0023] Reference Figure 1 and Figure 3 , Figure 1The precise mapping method for the electrical interface of the integrated verification test system for the aircraft power supply system provided in the first embodiment of this application can be executed based on an FPGA gateway or a real-time operating system (RTOS). The precise mapping method for the electrical interface of the integrated verification test system for the aircraft power supply system may include: S10. The first simulation signal is processed sequentially using a series cable voltage drop compensation algorithm, a voltage and current protection algorithm, a closed-loop delay compensation algorithm, and a fixed frequency sampling algorithm to obtain a first electrical simulation signal, which is then transmitted to the power drive device via a first high-speed synchronous real-time network. The second simulation signal is processed sequentially using a signal scaling algorithm, a channel output characteristic reverse simulation algorithm, and a fixed frequency sampling algorithm to obtain a second electrical simulation signal, which is then transmitted to the AO&DO board via a second high-speed synchronous real-time network. The third simulation signal is processed sequentially using a channel output characteristic reverse simulation algorithm and a fixed frequency sampling algorithm to obtain a third electrical simulation signal, which is then transmitted to the test exciter / measurement and control device via a third high-speed synchronous real-time network. The power drive device includes a power amplifier, a programmable power supply, and a switching power supply. In one embodiment of this application, the process of processing the first simulation signal using a series cable voltage drop compensation algorithm, a voltage and current protection algorithm, a closed-loop delay compensation algorithm, and a fixed frequency sampling algorithm to obtain the first electrical simulation signal may include the following: S101. Obtain the power hardwire impedance and load current, model output voltage and load voltage; S102. Process the first simulation signal according to the series cable voltage drop compensation algorithm to obtain the voltage drop compensation first signal. The series cable voltage drop compensation algorithm is to obtain the voltage drop compensation first signal based on the sum of the product of the model output voltage, the power hard wire impedance, and the load current. Specifically, the impedance Z of the power hardwire is measured. Assuming the original simulated output voltage value of the model is U1 and the load current is I, the value of the first voltage drop compensation signal sent to the power drive device after processing by the cable voltage drop compensation algorithm is U=U1+I*Z.

[0024] Clearly, under different current conditions, there will be varying degrees of voltage drop on the power hardwire connecting the power drive device to the physical test system, and the longer the cable, the greater the voltage drop, causing the voltage received by the physical test system to be lower than the model simulation output. By compensating for the voltage drop of the cable at the electrical power cross-linking interface, the model simulation output can be accurately transmitted to the physical test system.

[0025] S103. Determine whether the value of the voltage drop compensation first signal exceeds the threshold of the electrical interface of the power drive device connected to the physical test system according to the voltage and current protection algorithm. If it exceeds the threshold, terminate the output of the voltage drop compensation first signal; otherwise, continue to transmit the voltage drop compensation first signal. Specifically, the system determines whether the output value of the cable voltage drop compensation module exceeds the normal range threshold of the electrical interface of the power amplifier connected to the physical test system. If it does, the operation of the model in the digital simulation system must be stopped and the power amplifier output must be prohibited.

[0026] S103. Obtain the first delay time of the first signal for voltage drop compensation of the series cable being transmitted to the power drive device, the second delay time of the output voltage of the power drive device, the third delay time of the load current data collected by the load interface of the physical test system, and the fourth delay time of the feedback data being transmitted to the digital simulation system via the network. Determine the closed-loop delay compensation algorithm based on the sum of the first delay time, the second delay time, the third delay time, and the fourth delay time. Input the first signal for voltage drop compensation into the closed-loop delay compensation algorithm to obtain the first signal for delay compensation. It should be noted that the first signal after model processing drives the output voltage of the power drive device, and the load current extracted by the physical test system from the power drive device needs to be fed back to the model. In this data link, the network first delay time for the model simulation data to be output to the power drive device via the network through the digital simulation system is T1, the second delay time for the power drive device to respond to the simulation data and output voltage is T2, the third delay time for the physical test system to collect feedback data from the load interface is T3, and the fourth delay time for the feedback data to be transmitted to the digital simulation system via the network is T4. Therefore, the closed-loop delay time of the delay compensation first signal of this output link is Tdelay = T1 + T2 + T3 + T4. Depending on the configuration of different test systems, the closed-loop delay time is generally between a few microseconds and a few milliseconds.

[0027] Clearly, the loop delay compensation algorithm can offset the delay introduced by the power interface mapping loop, resulting in smaller simulation errors of the phase difference between voltage and current in the AC electrical interface and more accurate power factor analysis results; it also makes the simulation analysis results of the time index of control and protection functions under transient conditions such as surge, spike, and overshoot more accurate.

[0028] S105. Set a fixed sampling time based on the reciprocal of the highest sampling frequency, and output the delay compensation first signal at equal time intervals according to the fixed sampling time to obtain the first electrical simulation signal.

[0029] It is understandable that if the highest sampling frequency of the physical test system for the electrical interface is Fs (Hz), then the SampleTime attribute of all electrical output ports of the model will be set to 1 / Fs. It should be noted that all models in this application are digital simulation systems, which are built upon a real-time operating system (RTOS).

[0030] In one embodiment of this application, the process of processing the second simulation signal sequentially using a signal scaling algorithm, a channel output characteristic inverse simulation algorithm, and a fixed frequency sampling algorithm to obtain the second electrical simulation signal may include the following: The analog quantity, discrete quantity, and PMW signal are obtained based on the second simulation signal; The input analog, discrete, and PMW signals are processed sequentially using the preset first mapping rule base and the channel output characteristic reverse simulation algorithm to obtain the second electrical simulation signal.

[0031] The AO&DO board and the test exciter / control device are connected to the digital simulation system, and the signal conditioning box is connected to the AO&DO board. The process of sequentially processing the input analog, discrete, and PMW signals using the preset first mapping rule base and the channel output characteristic inverse simulation algorithm to obtain the second electrical simulation signal can include the following: Based on the signal mapping rules of the electrical board in the virtual-real fusion test of the aircraft power supply system, a first mapping rule library is determined. The first mapping rule library is used to process the input analog, discrete and PMW signals to obtain the simulation mapping signal. The inherent errors of the signal conditioning box, AO&DO board and test exciter / measurement and control device are obtained through offline calibration tests. Based on their inherent errors, the simulation mapping signal is reverse pre-compensated. A fixed sampling time is set according to the reciprocal of the highest sampling frequency. The simulation mapping signal after reverse pre-compensation is output at equal time intervals according to the fixed sampling time to obtain the second electrical simulation signal.

[0032] Specifically, the signal scaling ratio is automatically configured based on the electrical board signal mapping rule base of the aircraft power supply system virtual-real fusion test. The first mapping rule base is shown in the table below:

[0033] Clearly, the digital simulation system can utilize signal scaling algorithms to first consider the normal steady-state range of the analog output signal, and then perform scaling mapping after accounting for potential spikes in abnormal transient characteristics. This improves the completeness of the signal mapping and ensures that the virtual scene is accurately transmitted to the physical experimental system. Secondly, the conversion relationship between physical quantities such as high-voltage and ground-voltage signals and virtual Boolean state variables is established. Thirdly, the completeness of the output mapping of the differential PWM signal is considered. Finally, the discrete output of the model is 0 and 1. When the driving board outputs discrete quantities, the voltage of this discrete output is limited by the board's power supply voltage. By outputting the key discrete output quantities through analog channels and then scaling them with the analog signal, the voltage transient characteristics of the key electrical interface discrete quantities can be accurately mapped, verifying the impact of the transient characteristics of the controller on the system's operating state.

[0034] In one embodiment of this application, the process of processing the third simulation signal by sequentially using a channel output characteristic inverse simulation algorithm and a fixed frequency sampling algorithm to obtain the third electrical simulation signal may include the following: The inherent error was obtained through offline calibration experiments, and pre-compensation was performed using a characteristic inverse simulation algorithm to obtain the inverse compensation second signal. A fixed sampling time is set based on the reciprocal of the highest sampling frequency. The second inverse compensation signal is output at equal time intervals based on the fixed sampling time to obtain the third electrical simulation signal.

[0035] Specifically, adding a channel output characteristic reverse simulation algorithm after the signal scaling module and after the model port that needs to output data to the test exciter / control device can further improve the accuracy of the data.

[0036] Understandably, the reverse simulation algorithm for output characteristics is used for output channels with amplifier, conversion, and excitation circuits. After offline calibration tests to obtain the inherent error between the model output value and the actual measured value of the electrical interface at the physical test terminal, a pre-compensation algorithm is added to the model output port for correction. The pre-compensation algorithm can be implemented based on data fitting, neural network algorithms, AI intelligent algorithms, etc. The method for obtaining the inherent error of the electrical interface through offline calibration tests is as follows: Amplifier circuit channel mapping reverse simulation: By applying overvoltage, undervoltage, and normal voltage operating potential control signals used in the experiment, the actual output voltage of the output channel is measured, and the error of each channel is obtained as: Actual output voltage - Control output voltage. By applying the voltage and current to be converted, the actual output current and voltage of the output channel are measured, and the test results of each channel are compared to obtain the VI and IV curves of each channel for reverse simulation of the conversion circuit channel mapping. By applying the power supply and excitation control signals used in the experiment, the actual output voltage of the output channel is measured, and the error of each channel is obtained as: Actual output voltage - Control expected output for reverse simulation of the excitation circuit channel mapping.

[0037] S20. Process the second electrical simulation signal using the AO&DO board to obtain the second electrical signal and the third electrical signal; process the third electrical simulation signal using the business logic layer of the test exciter / measurement and control device to obtain the fifth electrical signal; process the first electrical simulation signal and the second electrical signal using the business logic layer of the power drive device to obtain the first electrical signal; process the third electrical signal using the signal conditioning box to obtain the fourth electrical signal. The low-voltage, low-current signals output by the AO&DO board need to be conditioned by a signal conditioning box into electrical simulation signals that can be directly connected to the physical device. Understandably, test exciters / control devices typically acquire the expected output of each channel and configure the channels via software or networks. Essentially, the signal conditioning box, test exciter, and control device all configure the channel electrical characteristics based on the control signals. The main implementation forms of channel configuration include amplification circuits, filtering circuits, linearization circuits, isolation circuits, conversion circuits, excitation circuits, and protection circuits. Amplification circuits amplify weak electrical simulation signals, such as mV-level voltages, to a suitable voltage. Filtering circuits remove noise or interference frequencies from the signal, retaining the effective signal. Linearization circuits correct the nonlinear output of the sensor, making it linear with the measured quantity. Isolation circuits disconnect the electrical connection between input and output, preventing interference, leakage, or high voltage damage to the equipment. Conversion circuits perform voltage-to-current, current-to-voltage, and impedance conversion. Excitation circuits provide the power supply or excitation signal required for the sensor's operation. Protection circuits are used to prevent overvoltage, overcurrent, static electricity, and other factors from damaging conditioning circuits or sensors.

[0038] Obviously, all simulation data in this application is sent to the power drive device, circuit board, test exciter, and measurement and control device connected to the physical test system via a high-speed synchronous real-time network. Specifically, these simulation data signals are first sent to the accompanying software of the power drive device, test exciter, and measurement and control device, and then the software controls the output of the relevant channels. In such software, where interactive operations are frequent and measurement and control data needs to be updated and displayed in real time, the application layer consumes a significant amount of time. The method in this application skips the original accompanying software application layer and directly controls the business logic layer based on the simulation data, which reduces the time consumed by the original accompanying software application layer and further improves the real-time performance of simulation data transmission.

[0039] It should be noted that the high-speed synchronous real-time network (such as TSN network or reflective memory fiber network) used in this application scheme for simulation data transmission has the following advantages compared with ordinary fiber optic and bus network transmission: (1) Hardware-level synchronization mechanism: Nanosecond-level timing control is achieved by using an FPGA-based gateway or real-time operating system (RTOS), which can ensure that the triggering and sampling of electrical simulation signals are strictly synchronized with the simulation step size of the virtual model; (2) Protocol-level timing alignment: Interpolation and alignment of frame timestamps of communication protocols (such as EtherCAT and PCIe) can solve the problem of physical bus delay and virtual simulation clock drift; (3) When multiple interface devices are used in large-scale power system virtual-real interaction tests, the high-speed synchronous real-time network can ensure that all virtual signals and physical signals can interact with a unified rhythm, ensuring the stability of the virtual-real interaction test system.

[0041] In summary, the precise electrical interface mapping method for virtual-real fusion testing of aircraft power supply systems proposed in this application has the following advantages: it adapts to aircraft power supply systems with different voltage levels and power supply systems; it does not require upgrading the hardware configuration of existing boards, power drive devices, signal conditioning boxes, test exciters, and measurement and control devices, and can achieve precise electrical interface mapping simply by adding relevant modules to the model, making it a low-cost method; it improves the integrity of physical drive signal characteristics and mapping integrity and accuracy, reducing virtual-real fusion test errors; and it ensures precise synchronization between the physical test system and the model simulation system, reducing mapping time lag.

This reduces the impact of signal noise from the physical test system on the accuracy of the analysis results of aircraft power supply system characteristic parameters (such as distortion spectrum) obtained from model simulation data.

[0043] Obviously, this application reads and parses data from a high-speed synchronous real-time network, adds a data filtering module to the model input port, and uses wavelet transform or Kalman filtering algorithms to eliminate noise interference. This application can reduce the impact of signal noise on the accuracy of the analysis results of aircraft power supply system characteristic parameters (such as distortion spectrum) obtained from model simulation data.

[0044] S50. The AI&DI board processes the input fourth and fifth physical drive signals to obtain the second physical mapping signal, which is then transmitted to the data filtering module via the second high-speed synchronous real-time network to obtain the second filtered signal. The business logic layer of the test exciter / measurement and control device processes the third physical drive signal, which is then transmitted to the data filtering module via the third high-speed synchronous real-time network to obtain the third filtered signal. S60. The first filtered signal is processed using a closed-loop delay compensation algorithm to obtain a delay-compensated third signal; the delay-compensated third signal is processed using a cable voltage drop compensation algorithm to obtain a voltage drop compensation second signal; the second filtered signal and the third filtered signal are processed using a channel output characteristic reverse simulation algorithm to obtain a reverse-compensated second signal and a reverse-compensated third signal respectively; the reverse-compensated second signal is processed using a signal restoration algorithm to obtain a restored signal; a fixed sampling time is set according to the reciprocal of the highest sampling frequency, and the voltage drop compensation second signal, the restored signal, and the reverse-compensated third signal are sampled according to the fixed sampling time to obtain the first to third sampled signals respectively. The first to third sampled signals are input to the model electrical simulation signal input port of the digital simulation system to drive the digital simulation system to simulate the power supply system model.

[0045] It should be noted that Real-Time Operating Systems (RTOS) can read and parse data from high-speed synchronous real-time networks. By adding data filtering algorithms to the input ports of the digital simulation system, the input signals can be filtered. Data filtering algorithms can be, for example, wavelet transform or Kalman filtering algorithms, thus eliminating noise interference. Based on this, this application can reduce the influence of signal noise on the physical test system, thereby improving the accuracy of the analysis results of aircraft power supply system characteristic parameters (such as distortion spectrum) obtained from model simulation data.

[0046] The channel output characteristic reverse simulation algorithm processes the filtered data from the input board and test exciter / control device through the channel input characteristic compensation module. For input channels with sampling circuits, linearization circuits, and conversion circuits, the algorithm performs offline calibration tests to obtain the inherent error between the actual measured value of the electrical interface at the physical test terminal and the received value at the model input port. Then, a post-compensation algorithm is added to the model input port to correct the received data from the physical test. The post-compensation algorithm can be implemented based on data fitting, neural network algorithms, AI intelligent algorithms, etc. The method for obtaining the inherent error of the electrical interface in the offline calibration test is as follows: Sampling circuit channel mapping correction: By applying control signals for overvoltage, undervoltage, and normal voltage operating points used in the test, the actual output voltage of the output channel is measured, and the error of each channel is obtained as: actual output voltage - control output voltage. Linearization circuit channel mapping correction: By applying different temperatures under the full temperature envelope of the test, the actual output voltage of the output channel is measured, and the error of each channel is obtained as: actual output voltage - expected linearized output voltage. Secondary correction of the linearization mapping parameters is then performed in the model. The conversion circuit channel mapping correction algorithm applies the voltage and current to be converted, measures the actual output current and voltage of the output channel, compares the test results of each channel, and obtains the VI and IV curves of each channel. The channel output characteristic reverse simulation algorithm can solve the problem of large accuracy differences and low consistency between electrical interface channels caused by non-standard customized amplifier circuits, conversion circuits, and excitation circuits.

[0047] Subsequently, this application uses a signal restoration algorithm to process the inversely compensated third signal to obtain the restored signal; The ratio of the sampled signal restored in the signal restoration algorithm is used to determine the restoration ratio. This ratio is automatically configured based on the signal mapping rule base of the aircraft power supply system's virtual-real fusion test electrical board.
