Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0029] Figure 1 FIG. 1 is a schematic diagram of a structure of a vehicle lightning indirect effect test system provided by an exemplary embodiment of the present application. Figure 1As shown, the automobile lightning indirect effect test system includes: a pulse electric field generator 1, a high-voltage plate 2, an electric field sensor 3, an optical transmitter 4, an optical receiver 5 and an oscilloscope 6; wherein, the pulse electric field generator 1 generates a high-voltage pulse signal, the high-voltage plate 2 is connected to the pulse electric field generator 1, the high-voltage plate 2 generates a high-voltage electric field under the action of the high-voltage pulse signal, the electric field sensor 3 is placed in the high-voltage electric field, the electric field sensor 3 is used to detect the electric field strength, the electric field sensor 3, the optical transmitter 4, the optical receiver 5 and the oscilloscope 6 are connected in sequence, and are used to collect and display the electric field strength detected by the electric field sensor 3.

Specifically, the present application can place the optical receiver 5 and the oscilloscope 6 in the control room to facilitate observation by operators and ensure the safety of operators. Preferably, the present application can also mark the high voltage electric field, that is, Figure 1 The 0#~8# in the figure mark the geometric center and the eight vertices of the cuboid respectively, so as to obtain a cuboid marking the uniform electric field domain, thereby facilitating the subsequent parking of the vehicle to be tested and ensuring the accuracy of the test.

[0030] Figure 2 FIG. 1 is a flow chart of a method for testing the indirect effects of lightning on a vehicle provided by an exemplary embodiment of the present application. The method for testing the indirect effects of lightning on a vehicle is applied to the above-mentioned system for testing the indirect effects of lightning on a vehicle, such as Figure 2 As shown, the automotive lightning indirect effect test method includes the following steps: Step 210: Turn on the pulse electric field generator to generate a high voltage pulse signal to the high voltage plate.

[0031] The present application generates a high-voltage pulse signal to the high-voltage plate by turning on the pulse electric field generator, so that the high-voltage plate generates a high-voltage electric field between the high-voltage plate and the ground, thereby simulating a lightning scene to achieve a lightning indirect effect test of the vehicle.

[0032] Step 220: Use an electric field sensor to collect the electric field strength between the high voltage plate and the ground.

[0033] The present application utilizes an electric field sensor to collect the electric field strength between the high-voltage plate and the ground to obtain the electric field strength at each position point in the space between the high-voltage plate and the ground to simulate a high-voltage electric field that meets the test requirements.

[0034] Step 230: Determine the electric field uniformity domain between the high voltage plate and the ground based on the electric field strength at multiple locations between the high voltage plate and the ground.

[0035] After collecting the electric field strength at multiple locations between the high-voltage pole plate and the ground, the present application obtains the electric field uniformity domain between the high-voltage pole plate and the ground based on the electric field strength at these locations, that is, obtains the area with uniform or consistent electric field strength within the spatial range between the high-voltage pole plate and the ground.

[0036] Step 240: placing the vehicle to be tested in a uniform electric field and starting the vehicle to be tested.

[0037] After knowing the electric field uniformity domain between the high-voltage plate and the ground, the present application places the vehicle to be tested in the electric field uniformity domain to perform an automotive lightning indirect effect test on the vehicle to be tested, and starts the vehicle to be tested during the test to simulate the electromagnetic compatibility quality of the vehicle to be tested when it is started (high-voltage power supply).

[0038] Step 250: Obtain status information of the vehicle to be tested.

[0039] During the test, a high-voltage pulse signal is generated by a pulse electric field generator to the high-voltage plate to generate a high-voltage electric field, and the status information of the vehicle to be tested in the high-voltage electric field is obtained to implement an indirect effect test of automotive lightning on the vehicle to be tested.

[0040] Step 260: Determine the lightning indirect effect test result of the vehicle to be tested based on the status information of the vehicle to be tested.

[0041] This application is based on the status information of the vehicle to be tested to determine whether the vehicle to be tested is in an abnormal state in the high-voltage electric field. If an abnormal state exists, it means that the vehicle to be tested has an abnormal state under the influence of the high-voltage electric field. At this time, it means that the electromagnetic interference quality of the vehicle to be tested is low. On the contrary, if there is no abnormal state, it means that the electromagnetic interference quality of the vehicle to be tested is high.

[0042] The automobile lightning indirect effect test method provided by the present application generates a high-voltage pulse signal to the high-voltage plate by turning on a pulse electric field generator; uses an electric field sensor to collect the electric field strength between the high-voltage plate and the ground; determines the electric field uniformity domain between the high-voltage plate and the ground based on the electric field strength at multiple positions between the high-voltage plate and the ground; places the vehicle to be tested in the electric field uniformity domain and starts the vehicle to be tested; obtains the status information of the vehicle to be tested; and determines the lightning indirect effect test result of the vehicle to be tested based on the status information of the vehicle to be tested; that is, uses a pulse electric field generator to generate a high-voltage pulse signal to the high-voltage plate to form a high-voltage electric field between the high-voltage plate and the ground, and determines the electric field uniformity domain between the high-voltage plate and the ground according to the electric field strength at multiple positions, places the vehicle to be tested in the electric field uniformity domain and starts the vehicle to be tested to obtain the status information of the vehicle to be tested in the electric field uniformity domain, so that the lightning indirect effect test result of the vehicle to be tested can be accurately determined, which is conducive to promoting the improvement of the electromagnetic compatibility quality of the vehicle.

[0043] In one embodiment, after step 220, the above-mentioned automobile lightning indirect effect testing method may further include: calibrating the operating parameters of the pulse electric field generator based on the electric field strength between the high-voltage plate and the ground.

[0044] Before the test, the present application generates a high-voltage pulse signal to the high-voltage plate through a pulse electric field generator to form a high-voltage electric field, and uses an electric field sensor to collect specific positions (such as the above Figure 1 The electric field strength of the pulse electric field generator is measured at the 0#~8# mark points in the test to determine whether the electric field strength at a specific location meets the test requirements, and the operating parameters of the pulse electric field generator are calibrated based on the electric field strength at the specific location to obtain a high voltage electric field that meets the test requirements.

[0045] In one embodiment, the above-mentioned automobile lightning indirect effect testing method may further include: using simulation to calculate the position information between the high-voltage plate and the ground and the theoretical electric field uniformity domain.

[0046] The present application can calculate the high-voltage electric field distribution between the high-voltage plate and the ground under the action of a set high-voltage pulse signal based on simulation software combined with relevant theoretical knowledge of electric fields, and determine the positional relationship between the high-voltage plate and the ground and the corresponding theoretical electric field uniformity domain, so as to provide a reference range for the electric field uniformity domain for subsequent tests.

[0047] In one embodiment, the specific calculation method of the position information and the theoretical electric field uniform domain between the high-voltage plate and the ground can be: calculating the theoretical electric field strength between the high-voltage plate and the ground; determining the control equation of the simulation software based on the theoretical electric field strength between the high-voltage plate and the ground; based on the control equation of the simulation software, simulating and calculating the simulated electric field strength between the high-voltage plate with set size and position information and the ground; determining the position information and the theoretical electric field uniform domain between the high-voltage plate and the ground based on the simulated electric field strength between the high-voltage plate and the ground.

[0048] Specifically, this application assumes that the distance between the two electrode plates (corresponding to the high voltage plate and the ground) is d, and the electrode plates carry charges Q and -Q respectively. Since the electric field is a scalar, the electric field has the same magnitude and direction on the two sides of the parallel electrode plates. According to Gauss's law, the electric field strength E=Q / (εA), where A is the area of ​​the electrode plate and ε is the dielectric constant; the charge Q=charge surface density σ×area A, so E=σ / ε, that is, between the electrode plates, the strength of the electric field is proportional to the charge surface density, the electric field strength distribution between the parallel electrode plates is uniform and proportional to the charge surface density, and the field strength inside the parallel plate capacitor is equal everywhere.

[0049] For the electric field in space, the electric field intensity E is a vector and a function of the spatial coordinates. The charge density in free space is ρ , and its relationship with the electric field is: ; in, is the divergence operator, is the dielectric constant in vacuum.

[0050] The divergence of the electric field E calculated on the left side of the above equation is a scalar field. The right side of the equation is a scalar. The electric field is an irrotational field. When walking around any closed path in the electric field, the loop integral of the electric field vector on the closed path is zero, that is: ; ; Where V is the scalar electric potential field.

[0051] The relationship between the electric field and the scalar field potential field is: ;Right now: ; Since the polarization effect of the dielectric field will change the electric field inside the material, the dielectric constant is taken as ,in, is the dielectric constant of the material as a multiple of the dielectric constant in vacuum. Thus, we can get: .

[0052] Based on the above formula as the control equation, this application uses simulation software to calculate the position information and theoretical electric field uniform domain between the high-voltage plate and the ground. Specifically, this application constructs a 5m×7m aluminum plate as a flat electrode, and the electrode is surrounded by Ø200mm aluminum tubes to ensure uniform edge electric field simulation, and the distance between the flat electrodes is 4m; and free tetrahedrons with good stability are selected as the basic unit for mesh design of the simulation body. In order to reduce redundant grids as much as possible and improve calculation efficiency and accuracy, the grid is designed in the order of points, lines, surfaces, and bodies, and the minimum grid size should be smaller than the minimum size grid of the model; in addition, the details are first meshed at the connection structure, and then expanded inward and outward at a certain growth rate. Finally, after multiple iterations, the grid design structure can better depict the geometric shape. The specific simulation three-dimensional stereogram is as follows. Figure 3 shown.

[0053] Further boundary conditions are set: zero charge on the outer surface, two parallel plates, the upper plate is connected to a potential of 400 kV, and the lower plate is grounded. The specific simulation results are as follows Figure 4-6 shown.

[0054] The simulated electric field E = voltage U / distance d = 400000v / 4m = 10000v / m. The simulation is basically consistent with the calculation, and the amplitude is basically consistent within 1m to 5m in the vertical direction (z direction) (such as Figure 7 As shown in the figure), the basic amplitude is consistent within 1m to 7m in the horizontal direction (y direction) (as shown in the figure). Figure 8 As shown in the figure), the basic amplitude is consistent within 2m to 4m in the horizontal direction (x direction) (as shown in the figure). Fig. 9 as shown).

[0055] Preferably, for a vehicle longer than 5 meters (ie, the length of the vehicle exceeds the length range of the electric field uniformity domain), the vehicle can be divided into sections for electric field assessment by moving the vehicle position.

[0056] In one embodiment, the specific implementation method of the above step 230 can be: based on the theoretical electric field uniform domain between the high-voltage plate and the ground, determine multiple boundary position points of the theoretical electric field uniform domain between the high-voltage plate and the ground; wherein the multiple boundary position points constitute a geometric body; based on the electric field strength of the multiple boundary position points, determine the electric field uniform domain between the high-voltage plate and the ground.

[0057] After simulating and obtaining the theoretical electric field uniform domain between the high-voltage plate and the ground, the present application determines multiple boundary position points of the theoretical electric field uniform domain between the high-voltage plate and the ground based on the theoretical electric field uniform domain, and obtains a geometric body to ensure that the geometric body area is an area with consistent electric field strength, and by detecting the electric field strength of the multiple boundary position points, it is determined that the vertices of the geometric body are within the electric field uniform domain, thereby determining the electric field uniform domain between the high-voltage plate and the ground.

[0058] In one embodiment, the high-voltage plate is arranged above the vehicle to be tested, and the distance between the high-voltage plate and the ground is greater than twice the height of the vehicle to be tested; wherein, the specific implementation method of the above step 250 can be: turning on the pulse electric field generator at least three times to generate a positive polarity high-voltage pulse signal to the high-voltage plate, and obtaining the status information of the vehicle to be tested; turning on the pulse electric field generator at least three times to generate a negative polarity high-voltage pulse signal to the high-voltage plate, and obtaining the status information of the vehicle to be tested.

[0059] After checking that the appearance and structure of the vehicle to be tested are intact, this application measures and records the test environment temperature, relative humidity and other environmental information, then arranges the electric field sensor outside the vehicle to set monitoring points and connects the optical transmitter, optical receiver and oscilloscope to test and complete data transmission debugging, operates the pulse electric field generator, sets the operating parameters of the pulse electric field generator to the calibrated operating parameters; sets the positive polarity test, monitors the voltage waveform output by the pulse electric field generator and the electric field monitoring waveform of the set monitoring point, and records it, operates the pulse electric field generator, and performs no less than 3 pulse outputs; sets the negative polarity test, monitors the voltage waveform output by the pulse electric field generator and the electric field monitoring waveform of the set monitoring point, and records it, operates the pulse electric field generator, and performs no less than 3 pulse outputs. Observe the vehicle status during the test. If an abnormality occurs, stop the test immediately. Continue only after analyzing and confirming safety. After the test is completed, turn off the vehicle power supply and dismantle the test layout facilities.
