However, with the rapid development of electronic technology, the electromagnetic environment has become increasingly complex, especially the threat of electromagnetic pulses (EMPs) to electronic devices has become increasingly prominent. An electromagnetic pulse is an instantaneous and high-intensity change in the electromagnetic field, which can be coupled into electronic devices through various channels, causing a decline in device performance, data loss, or even permanent damage, posing a serious threat to key infrastructures such as military systems, communication systems, and power systems.

[0003] Traditional electromagnetic pulse protection methods mainly rely on technical means such as physical shielding, grounding, and filtering. These methods can reduce the impact of electromagnetic pulses on electronic devices to a certain extent, but have many limitations. For example, although physical shielding can effectively block the direct impact of external electromagnetic pulses, its protection effect on electromagnetic pulses generated inside the device or coupled in through other channels is limited; grounding and filtering technologies rely on a good grounding system and filter design, and their protection capabilities are still insufficient when facing high-intensity electromagnetic pulses.

[0004] In addition, traditional methods often lack intelligence and self-adaptability, and cannot dynamically adjust the protection strategy according to the actual intensity of the electromagnetic pulse and the real-time state of the device, resulting in unstable protection effects.

[0058] As Figure 2 shown, an electromagnetic pulse protection device includes an electromagnetic pulse monitoring module, an electromagnetic pulse protection device, an electromagnetic pulse communication module, and a monitoring module; the electromagnetic pulse monitoring module is connected to the electromagnetic pulse protection device; the electromagnetic pulse monitoring module, the electromagnetic pulse protection device, and the electromagnetic pulse communication module are respectively connected to the monitoring module;

[0059] The electromagnetic pulse monitoring module monitors the electromagnetic pulse energy impact in the circuit. When the electromagnetic pulse energy reaches the preset minimum voltage or minimum current value of the electromagnetic pulse protection device, the electromagnetic pulse protection device is activated to clamp the voltage or current to less than the preset value. The electromagnetic pulse communication module is used to feedback the protection data of the electromagnetic pulse protection device and the health status of the electromagnetic pulse protection device collected by the monitoring module, and output real-time monitoring signals and detection result signals.

[0060] The electromagnetic pulse monitoring module includes an RC trigger device module and a signal sampling module.

[0061] The RC trigger device module is used to activate the electromagnetic pulse protection device and introduce electromagnetic pulses when the electromagnetic pulse wave energy impact value in the circuit reaches the preset threshold. The signal sampling module is used to judge and convert the pulse energy.

[0062] The electromagnetic pulse monitoring module further includes a controllable discharge gap with an arc extinguishing circuit. The controllable discharge gap is used to control the operation of the electromagnetic pulse protection device when the applied voltage value or current value exceeds the starting voltage value.

[0063] The electromagnetic pulse protection device includes a varistor component and an FS high-pass filter module. The varistor component includes a dual-energy wave sensitive ceramic element and a controllable capacitance filter.

[0064] The dual-energy wave sensitive ceramic element can simultaneously withstand the impact of a 10 / 350 μs + 8 / 20 μs combined wave, and has the ability to withstand a 500 A impact of a 20 / 500 ns PCUI double-exponential wave. The combined wave limiting voltage is less than 700 V.

[0065] The controllable capacitance design filter has a reliable thermal tripping device and adopts a varistor-gap series structure. The FS high-pass filter module is used to divert pulse energy when the device is activated.

[0066] The electromagnetic pulse communication module includes an on-site device counting and display module and a device remote communication module. The on-site device counting and display module is used to display the real-time monitoring data of the electromagnetic pulse monitoring module on the device panel in real time. The remote communication module transmits the real-time monitoring data of the monitoring module and the prevention and control instructions given by the background center in real time through the device communication interface.

[0067] Specifically, the electromagnetic pulse protection method of the present invention specifically includes the following steps:

[0068] Step 1: Health monitoring and replacement

[0069] The electromagnetic pulse protection monitoring module first obtains the health status of the electromagnetic pulse protection device. This health status is calculated based on the operating duration of the electromagnetic pulse protection device and the fatigue coefficient, where the fatigue coefficient is defined as the ratio of the duration of exposure to electromagnetic pulses during the operating duration of the electromagnetic pulse protection device to the total operating duration. If the health status is lower than the set health status threshold, it indicates that the electromagnetic pulse protection device has approached or reached its service life limit, and the protection effect may decrease significantly. At this time, the electromagnetic pulse protection device needs to be replaced to ensure the effectiveness of protection. Otherwise, proceed to the next step.

[0070] Step Two: Electromagnetic Pulse Protection Evaluation

[0071] The electromagnetic pulse evaluation module generates an electromagnetic pulse protection evaluation container based on the electromagnetic pulse tolerance energy limit of the target protection device and the health status of the electromagnetic pulse protection device. This container is connected to the electromagnetic pulse protection monitoring module and is used to receive and process the data transmitted by the monitoring module. By comparing the relationship between the current intensity of the electromagnetic pulse and the degree of interference of the target protection device, as well as the difference between this relationship and the reference relationship (i.e., the corresponding relationship between the initial intensity of the electromagnetic pulse and the degree of interference of the target protection device), the protection deviation amount of the electromagnetic pulse protection device is calculated. This deviation amount reflects the gap between the protection device in actual use and the ideal protection state.

[0072] Step Three: Protection Deviation Calibration

[0073] The relationship between the electromagnetic pulse intensity and the degree of interference of the target protection device obtained in Step Two is sent to the protection deviation calibration module. This module calibrates the protection device according to the protection deviation amount of the electromagnetic pulse protection device to eliminate or reduce the deviation. The calibrated electromagnetic pulse protection intensity is obtained by adjusting the parameters or strategies of the protection device under the same degree of interference, aiming to more accurately match the actual needs of the target protection device. The calibration result is then sent to the electromagnetic pulse protection device to guide subsequent protection control.

[0074] Step Four: Real-time Monitoring of the Degree of Interference

[0075] The data acquisition device continuously collects data on the degree of interference of the target protection device and compares it with the preset target degree of interference. If the real-time degree of interference is not greater than the target degree of interference, it indicates that the current protection strategy is effective and no further adjustment is required. Directly proceed to Step Seven to complete the control of the protection device. Otherwise, according to the difference between the target degree of interference and the real-time degree of interference, proceed to the next step for dynamic adjustment of the protection intensity.

[0076] Step Five: Dynamically Adjust the Protection Intensity

[0077] Based on the interference difference obtained in Step 4, calculate the electromagnetic pulse energy to be suppressed, and then determine the protection intensity required for the electromagnetic pulse protection device. According to this calculation result, the control module of the electromagnetic pulse protection device adjusts the protection equipment to the required protection intensity until the real-time interference level is reduced below the target interference level, and then proceeds to the next step for further fine-tuning.

[0078] Step 6: Correct the protection intensity

[0079] To further improve the accuracy of protection, the present invention also considers the change amount of the interference level per unit time (i.e., the change amount of interference level per unit time), and calculates the change amount of electromagnetic pulse energy per unit time based on this change amount. Based on this change amount, calculate the corrected protection intensity of the electromagnetic pulse protection device and make corresponding adjustments to the protection intensity of the protection equipment. This step ensures that the protection strategy can be dynamically adjusted with the change of the electromagnetic environment and maintain the best protection effect.

[0080] Step 7: Complete the control of the electromagnetic pulse protection device

[0081] After calibration, adjustment, and correction through the above steps, the electromagnetic pulse protection device has reached the best protection state according to the current electromagnetic environment and the actual requirements of the target protection equipment. At this time, complete the control process of the electromagnetic pulse protection device to ensure that the equipment can operate stably in a complex electromagnetic environment.

[0082] To achieve the above invention purpose, the present invention also provides an electromagnetic pulse protection device, which applies the above electromagnetic pulse protection method and includes key components such as an injection interference sampling unit, an electromagnetic pulse evaluation module, an electromagnetic pulse protection device, an electromagnetic pulse protection monitoring module, a data processing module, and a data acquisition module.
