Description

Technical Field

[0001] The present invention relates to the field of electromagnetic environment effect test, and in particular to a semi-physical simulation method and device for electromagnetic environment effect test. Background Art

[0002] With the rapid development of microelectronics technology, the integration and miniaturization of microelectronic devices are constantly improving, and the overvoltage, overcurrent and electromagnetic resistance of electronic devices are reduced, resulting in the gradual increase of electromagnetic vulnerability of electronic equipment. At present, the power of various electromagnetic radiators, such as radar, communication and other radiation sources, is getting larger and larger, the number of radiation sources is increasing exponentially, and the spectrum is getting wider and wider, making the electromagnetic environment more complex and deteriorating. These complex electromagnetic environments cause electronic equipment to have functional disorders, performance degradation and even damage. Therefore, in view of complex electromagnetic environments, how to ensure the normal operation of electronic equipment is a research hotspot in the field of electromagnetic environment at home and abroad. The effect of the interaction between complex electromagnetic environment and electronic equipment is manifested in the macroscopic form of the impact and damage to electronic equipment. Its physical essence lies in the effect mechanism of the action process of electromagnetic waves and effectors. Therefore, studying the characteristics of electromagnetic environment and its action mechanism is the key to solving such problems. In recent years, great progress has been made in the electromagnetic environment effect test and evaluation technology, and corresponding test methods and standards have been formed.

[0003] Electromagnetic Environmental Effects (E3) can be summarized as the impact of the electromagnetic environment on the working ability of personnel, equipment, systems and platforms. The electromagnetic environment involved in the electromagnetic environmental effects includes both artificial electromagnetic environments such as radio frequency systems, ultra-wideband devices, high-power microwave systems, and electromagnetic pulses, as well as natural electromagnetic environments such as lightning and static electricity. From a disciplinary perspective, electromagnetic environmental effects involve electromagnetic compatibility (EMC), electromagnetic interference (EMI), electromagnetic vulnerability (EMV), electromagnetic pulse (EMP), electronic protection (EP), electrostatic discharge (ESD), and electromagnetic radiation hazards (EMRADHAZ).

[0004] Among foreign military standards for electromagnetic environmental effects, the US military standards have the most extensive influence. The core standards are the system-level MIL-STD-464C "Requirements for System Electromagnetic Environmental Effects" and the equipment-level MIL-STD-461G "Requirements for Control of Electromagnetic Interference Characteristics of Equipment and Subsystems". NATO's representative electromagnetic environmental effect standards mainly include the AECTP-250 series "Electrical and Electromagnetic Environmental Conditions" and the AECTP-500 series "Electromagnetic Environmental Effects Test and Verification". The international civil standards involving electromagnetic environmental effects mainly include the IEC61000 series and the CISPR series, and this type of standards is still being supplemented and improved. While carrying out electromagnetic compatibility engineering practices, my country has also carried out electromagnetic compatibility test research and facility construction, and has the ability to test equipment-level electromagnetic compatibility and system-level electromagnetic environmental effects.

[0005] Electromagnetic environment effect test is an important means of qualitatively, quantitatively or comprehensively evaluating the impact of complex electromagnetic environment on effectors (electronic devices, links, equipment or systems). It is mainly based on correct theoretical foundations, uses appropriate test methods and means to obtain high-reliability test data, and adopts scientific and reasonable evaluation systems and methods to make a comprehensive and objective evaluation of the effectiveness of effectors in complex electromagnetic environments. Through electromagnetic environment effect test, the degree of influence of complex electromagnetic environment on effectors can be evaluated, and then the index performance and application effectiveness of effectors under different electromagnetic environment conditions can be estimated. This is of great significance for studying the mechanism of electromagnetic environment effect, analyzing and verifying and improving the function and index design of effectors in complex electromagnetic environments.

[0006] However, the interaction between the electromagnetic environment and the effector involves a variety of mutually influencing physical variables, making it difficult to perform pure numerical simulation of the interaction process or difficult to achieve the desired purpose. In addition, the various random factors that are difficult to control in the actual test process indicate that only theoretical analysis or pure numerical simulation to predict or evaluate the electromagnetic effect test results will inevitably lead to differences between the calculated results and the test results. At the same time, due to the complexity of electronic equipment, the uncertainty of the development process and the diversity of the electromagnetic environment distribution, solving the electromagnetic environment effect problem of electronic equipment must rely on a large number of tests and actual measurements. Although the full physical effect test can provide the closest simulation to the real situation, its shortcomings cannot be ignored, such as high cost, long cycle, difficulty in simulating extreme conditions and difficulty in repeating experiments.

[0007] In electromagnetic effect testing, the use of hardware-in-the-loop (HIL) has many advantages, especially in the fields of high-power microwave, electromagnetic interference (EMI), electromagnetic compatibility (EMC), etc. The HIL method is a real-time simulation form that connects mathematical models and physical models (physical effect models) that replace physical objects to the actual test loop. It is an ideal electromagnetic effect test research method that can approach physical testing. It has significant advantages such as high universality, high repeatability, and low cost-effectiveness, making it an important branch in the field of simulation.

[0008] Compared with the traditional pure physical and pure simulation electromagnetic effect test methods, the establishment of a semi-physical simulation platform for electromagnetic environment effect testing has the following advantages:

[0009] 1) Reduce costs: Real electromagnetic effect test equipment and test environments are usually expensive, especially when complex or large systems are involved. Semi-physical simulation reduces the need for expensive equipment and facilities by simulating part of the system or environment, thereby reducing experimental costs. At the same time, it can also reduce the need for material loss, especially in high-power microwave experiments, where physical devices may be easily damaged or exhausted. Especially in the absence of effectors, semi-physical simulation can build mathematical models through the host computer and smoothly carry out relevant experimental research, providing an efficient and economical solution for electromagnetic environment effect testing.

[0010] 2) Real-time operation, efficient experiment: In the process of electromagnetic effect testing, it is very important to simulate the dynamic response between the real electromagnetic field and the equipment. Compared with frequently rebuilding or adjusting the physical test platform, the semi-physical simulation platform can quickly iterate and modify the test conditions, adjust the simulation model and simulation parameters according to the functions and different indicators of the effector concerned in the test, so that researchers can interact with the actual hardware on a real time scale, quickly verify different electromagnetic effect models and assumptions, and directly observe the dynamic response of the system.

[0011] 3) High fidelity: Compared with pure physical testing methods, the semi-physical simulation platform involved in the present invention can customize the mathematical model of the effector required for the test, so that it has the same response characteristics as the physical object. The interaction process between the electromagnetic environment and the effector involves a variety of mutually influential physical variables, and there are various unpredictable random factors in the actual testing process, making it impossible for pure numerical simulation to simulate the actual situation during the test in real time. Therefore, compared with pure numerical simulation, the semi-physical simulation platform involved in the present invention is closer to the actual test environment of the electromagnetic effect test.

[0012] 4) Convenient for mechanism analysis: The semi-physical simulation platform replaces the physical object with a mathematical model, and can quickly generate a large amount of effect data according to the test requirements, which has the statistical advantage of electromagnetic environment effect mechanism analysis. The amount of data in the electromagnetic environment effect test database is usually limited. Given the premise that a large amount of data is required for the study of the electromagnetic environment effect mechanism, the present invention can quickly generate a large amount of effect data, which has the statistical advantage of electromagnetic environment effect mechanism analysis and can provide a basis for the parametric design of the effector.

[0013] 4) Cross-validation and optimization: The semi-physical simulation platform is highly flexible and is not limited to a single effector or electromagnetic effect test. It allows researchers to cross-validate the accuracy of different effector models and electromagnetic effect models, and optimize the models while obtaining simulation results. When testing the anti-interference ability of new materials, electronic devices or systems, the semi-physical simulation platform can be used as a method to verify and optimize the design in advance.

[0014] 5) The test environment is controllable and repeatable: In the actual physical environment, the test conditions may be difficult to fully reproduce, especially under high-power electromagnetic fields or complex interference conditions. Semi-physical simulation provides a highly controllable and repeatable test environment, which can reproduce the conditions that the device may encounter in the actual working environment or accurately reproduce the same experimental conditions. This consistency is very important for the verification of experimental data and the refinement of theoretical models.

[0015] Therefore, it is necessary to provide a semi-physical simulation technology for electromagnetic environment effect testing. Summary of the invention

[0016] The present invention provides a semi-physical simulation method and device for electromagnetic environment effect test, aiming to solve the problem that experimental conditions may be difficult to fully reproduce in the actual physical environment, especially under high-power electromagnetic fields or complex interference conditions, and the existing electromagnetic environment effect test platform is difficult to build and the test cost is high.

[0017] In one aspect, the present invention provides a semi-physical simulation method for electromagnetic environment effect test, the method comprising the following steps:

[0018] Determine the effectors on the signal link of the electromagnetic environment effect test;

[0019] Collecting the preceding link signal of the link where the effector is located and using it as an input signal for semi-physical simulation;

[0020] After the input signal is calibrated and the signal power is adjusted through the automatic gain controller, waveform data acquisition is performed;

[0021] The host computer generates corresponding output waveform data through numerical calculation (such as amplification, attenuation, filtering, etc.) according to the input signal and the effector function to be simulated;

[0022] Generate waveform data of an output signal based on a waveform data generation method configured by a user;

[0023] Based on the waveform data and the power requirement of the input signal of the subsequent link of the effector, an output signal of the effector port is generated and transmitted to the subsequent link of the link where the effector is located.

[0024] On the other hand, the present invention also provides a semi-physical simulation device for electromagnetic environment effect test, which is applied to the signal link of the electromagnetic environment effect test to simulate the effector in the signal link and the electromagnetic environment around it. The device includes: a signal acquisition module, a host computer and a signal generation module;

[0025] in,

[0026] The signal acquisition module is used to receive the front link signal of the link where the effector is located, calibrate and adjust the signal power of the received front link signal, and then collect waveform data and upload it to the host computer;

[0027] The host computer is used to simulate the effector and the electromagnetic environment around it, and program the working mode and working parameters of the signal acquisition module, analyze and process the waveform data uploaded by the signal acquisition module, and generate the waveform data of the output signal based on the waveform data generation method configured by the user and send it to the signal generation module;

[0028] The signal generation module is used to generate an output signal of the effector port according to the waveform data of the received output signal, and transmit it to the subsequent link of the link where the effector is located.

[0029] The present invention builds a corresponding numerical substitution model according to the required effector parameter index to simulate the effector. The index parameters can be derived from the actual test data of the required substitution, and can also be customized according to needs.

[0030] The principle of the semi-physical simulation method and device for electromagnetic environment effect test provided by the present invention is that first, the input signal of the front-stage link is collected by the signal acquisition module to obtain all the inputs of the front-stage link of the link where the original effector is located; then, the electromagnetic environment of the effector and its surroundings is simulated by the host computer; finally, according to the simulation result, the output waveform of the port where the effector is located is generated by the signal generation module, and output to the back-stage link of the link where the original effector is located, that is, the simulation and evaluation of the electromagnetic environment effect is realized by replacing the hardware with software. The semi-physical simulation device provided by the present invention will realize the equivalent replacement of hardware by software, that is, on the basis of retaining the electromagnetic environment effect test conditions where the effector is located, the impact on the overall link is considered. Among them, the implementation method of the software equivalent replacement of hardware is that, based on the actual test environment, according to the function and technical indicators of the effector, the mathematical model is used to replace the physical object to approximate the actual test results of the electromagnetic environment effect test. Replacing the corresponding physical object with a mathematical model can verify the reliability of devices, links, equipment and even the overall system in a real test environment, and the rapid evaluation of its performance indicators.

[0031] Furthermore, the signal acquisition module includes an input-end automatic gain control unit and an oscilloscope, wherein the input-end automatic gain control unit is used to adjust the signal power of the front-end link to prevent damage to the oscilloscope; after receiving the output signal of the input-end automatic gain control unit, the oscilloscope collects waveform data and displays it in real time, and uploads the collected waveform data (such as data transmission via Ethernet) to the host computer.

[0032] Furthermore, the host computer includes a signal processing unit, a human-computer interaction interface, and a control and data transmission unit, wherein the signal processing unit is used to analyze and process the waveform data uploaded by the signal acquisition module, and generate output signal waveform data; the human-computer interaction interface provides a graphical interactive interface for users to perform semi-physical simulation operations (such as model building, simulation, generation of output signals and related control instructions of effectors); the control and data unit is used to program the working parameters of the test instrument, signal acquisition module and signal generation module to complete the reception of waveform data, the sending of control instructions and the power adjustment of the transmission signal;

[0033] That is, in the present invention, the host computer has the important functions of receiving waveform data and sending control instructions; the host computer can analyze and process the collected front-end link signals; according to the actual experimental requirements, the mathematical model of the effector required for the test is built to make it have the same response characteristics as the real object; through the operation control and data transmission unit, Ethernet is used to communicate with the oscilloscope and arbitrary waveform generator.

[0034] Furthermore, the human-computer interaction interface can also be used to monitor and process the input waveform data in real time, so as to generate the output signal waveform data and its signal generation control instructions to be transmitted to the signal generation module according to the different requirements of the effector function in the electromagnetic effect test, and monitor the output waveform.

[0035] Furthermore, the human-computer interaction interface can also be used to call a matching control strategy in a preset control strategy set according to the functional requirements of the effector in the electromagnetic effect test, and optimize and adjust the effector model.

[0036] Furthermore, the human-computer interaction interface is also used to remotely control relevant test instruments for electromagnetic environment effect tests, receive feedback data from the test instruments, and send control instructions to the test instruments to control their working parameters and working modes; read the loss and phase shift of the test link, and correct or compensate the link.

[0037] Furthermore, the signal generation module includes an arbitrary waveform generator and an output-end automatic gain control unit, wherein the arbitrary waveform generator is used to receive waveform data generated by a host computer and generate a radio frequency signal required for the test; the output-end automatic gain control unit adjusts the signal power of the generated radio frequency signal, and then transmits the radio frequency signal to the subsequent link of the link where the effector is located, so as to achieve adjustment of the output power of the radio frequency signal transmitted to the subsequent link.

[0038] Furthermore, the control and data transmission unit regulates the oscilloscope, arbitrary waveform generator and input / output automatic gain control unit to ensure that the test instrument adjusts the input, reading and signal power of the data. At the same time, after the front-end link signal is processed by the signal processing unit, the control and data transmission unit program-controls the oscilloscope and the input automatic gain control unit and sends control instructions to the arbitrary waveform generator.

[0039] Furthermore, the control operations performed by the user through the human-computer interaction interface of the host computer include:

[0040] (1) Remotely control the relevant test instruments of the electromagnetic environment effect test, receive feedback data from the test instruments, and send control instructions to the test instruments to control their operating parameters and working modes; read the loss and phase shift of the test link, and correct or compensate the link.

The oscilloscope collects the input signal waveform of the front-end link and monitors the collected waveform data in real time.

[0055] The host computer builds a mathematical model in a highly integrated software environment and monitors the operating status of the electromagnetic environment effect test in real time.

[0056] The signal generation module is responsible for receiving the signal generation instructions, outputting the RF signal and adjusting the signal power, and transmitting it to the subsequent link. The arbitrary waveform generator parses the relevant instructions sent by the control unit, and generates the RF signal required for the test based on the received data. The automatic gain control unit adjusts the power of the generated RF signal and transmits it to the subsequent link.

[0057] The workflow of each module unit of a semi-physical simulation method and device for electromagnetic environment effect test provided by an embodiment of the present invention is as follows:

[0058] The signal acquisition module is used to obtain all inputs of the previous link of the link where the original effector is located. Specifically, the automatic gain control unit is used to adjust the input signal power of the previous link; and the oscilloscope is used to collect and display the input waveform of the previous link in real time.

[0059] Subsequently, the host computer is used to simulate the electromagnetic environment of the effector and its surroundings.

[0060] Finally, according to the simulation results, the signal generation module generates the output waveform of the port where the effector is located, and outputs it to the subsequent link of the link where the original effector is located. Specifically, the arbitrary waveform generator is used to receive the waveform data generated by the host computer, and generate the RF signal required for the test according to the received data; the automatic gain control unit is used to adjust the output power of the generated RF signal at the output end and transmit it to the subsequent link.

[0061] In one embodiment, see Figure 2 The working process of a semi-physical simulation method and device for electromagnetic environment effect test provided by the embodiment of the present invention specifically includes:

[0062] Step 1: The test instrument needs to be calibrated during the preparation stage of the electromagnetic environment effect test. The link loss and phase shift need to be considered during signal acquisition and signal output, and corresponding corrections or compensations need to be made.

[0063] Step 2: Collect the front link signal using the signal acquisition module;

[0064] Collect the input signal of the front-stage link, and the front-stage link signal is connected to the input-end automatic gain control unit by wire or wireless means to avoid damaging the oscilloscope; the input-end automatic gain control unit adjusts the input signal power of the front-stage link before transmitting it to the oscilloscope, and the oscilloscope communicates with the host computer via Ethernet.

[0065] Step 3: Based on the actual test requirements, the user builds the mathematical model required for the test based on the host computer so that it has the same response characteristics as the actual object, so as to generate waveform data of the output signal;

[0066] The signal processing unit of the host computer analyzes and processes the waveform data of the front link collected by the oscilloscope of the signal acquisition module, and provides waveform data for the waveform generation module.

[0067] Based on the human-computer interaction interface of the host computer, you can customize the waveform data generation method with the same response characteristics as the real object. There are three ways to generate the output signal:

[0068] (1) Generate corresponding output signals by establishing an effector simulation model;

[0069] (2) Directly generate output signals based on system transfer functions through autonomous programming;

[0070] (3) Directly generate waveform data as output signal by calling third-party simulation software.

[0071] The signal processing unit of the host computer transmits the generated output signal waveform data to the arbitrary waveform generator through the control and data transmission unit; the control and data transmission unit is mainly used to receive the data collected by the oscilloscope, send control instructions to the arbitrary waveform generator, and adjust the input\output signal power.

[0072] Step 4: Use the signal generation module to generate a signal input to the subsequent link;

[0073] The arbitrary waveform generator of the signal generation module parses the control instructions sent by the control and data transmission unit, and generates the RF signal required for the test based on the received waveform data. The RF signal can be transmitted to the automatic gain control unit of the signal generation module via wired (coaxial line, waveguide, microstrip line, etc.) or wireless means. The automatic gain control unit first performs self-calibration and completes signal power adjustment before transmitting it to the subsequent link.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
