Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0054] The embodiments of the present application provide an electromagnetic pulse protection control method, system and terminal device for electronic equipment, which solve the technical problem that the control system of existing electromagnetic pulse protection devices has insufficient reliability and resilience and cannot ensure that they can continue to operate at critical moments.

[0055] Example 1:

[0056] FIG1 is a flowchart of the steps of the electromagnetic pulse protection control method for an electronic device according to an embodiment of the present application.

[0057] As shown in FIG1 , an embodiment of the present application provides an electromagnetic pulse protection control method for an electronic device, comprising the following steps:

[0058] S1. Acquire electromagnetic pulse data of target electronic equipment in real time.

[0059] It should be noted that in step S1, electromagnetic pulse data of electromagnetic radiation around the target electronic device is obtained. In this embodiment, the target electronic device can be an electronic device that can be affected by electromagnetic pulses, such as a transformer and a mobile phone.

[0060] S2. Process and analyze the electromagnetic pulse data to obtain the signal strength and signal frequency corresponding to the electromagnetic pulse data.

[0061] It should be noted that in step S2, the electromagnetic pulse data obtained in step S1 is processed and analyzed to obtain signal strength and signal frequency, providing data for determining whether an EMP event has occurred.

[0062] In the embodiment of the present application, the electromagnetic pulse data is analyzed using a relatively mature existing spectrum analysis method to obtain the signal frequency corresponding to the electromagnetic pulse data. The amplitude of the electromagnetic pulse data is measured using a signal strength measuring instrument to obtain the signal strength corresponding to the electromagnetic pulse data.

[0063] It should be noted that the signal strength measuring instrument may be a signal strength tester.

[0064] S3. Determine whether an EMP event has occurred based on a comparison and analysis of the signal strength, signal frequency, and electromagnetic pulse data with corresponding specific thresholds and a database of known EMP events.

[0065] It should be noted that in step S3, the signal strength and frequency are first compared with corresponding specific thresholds to preliminarily determine whether an EMP event may have occurred in the target electronic device. Then, if an EMP event may have occurred in the target electronic device, the electromagnetic pulse data is compared with signals in a database of known EMP events to determine whether an EMP event has occurred in the target electronic device. In this embodiment, if the signal strength and frequency exceed the corresponding specific thresholds, the target electronic device is determined to have likely experienced an EMP event; otherwise, the target electronic device is determined to have not experienced an EMP event. If a signal matching the electromagnetic pulse data is found in the database of known EMP events, the target electronic device is determined to have experienced an EMP event; otherwise, the target electronic device is determined to have not experienced an EMP event. The specific thresholds can be set as needed. An EMP event refers to a strong electromagnetic pulse (EMP) event, which is a sudden, high-intensity electromagnetic radiation phenomenon. The electromagnetic pulse generated by an EMP event has extremely high energy and frequency, and can release a large amount of electromagnetic energy in a short period of time, causing significant damage to electronic equipment and power systems.

[0066] S4. If an EMP event occurs, implement a protective strategy to protect the target electronic device. This strategy includes shutting off the power supply to the target electronic device and switching the target electronic device's primary operating system to a redundant system, using the redundant system to control the target electronic device's operation.

[0067] It should be noted that, in step S4, after it is determined that an EMP event occurs in the target electronic device according to step S3, a protection strategy is adopted to control the operation of the target electronic device.

[0068] The present application provides an electromagnetic pulse protection control method for electronic equipment, comprising acquiring electromagnetic pulse data of a target electronic device in real time; processing and analyzing the electromagnetic pulse data to obtain signal strength and signal frequency corresponding to the electromagnetic pulse data; determining whether an EMP event has occurred based on comparison and analysis of the signal strength, signal frequency, and electromagnetic pulse data with corresponding specific thresholds and a database of known EMP events; and if an EMP event has occurred, adopting a protection strategy to perform protective operations on the target electronic device; wherein the protection strategy includes cutting off the power supply of the target electronic device and switching the main system operating the target electronic device to a redundant system, and using the redundant system to control the operation of the target electronic device. By applying the electromagnetic pulse protection control method for electronic equipment to the electronic device, the electronic device adopts the protection strategy to protect it after an EMP event occurs, allowing the electronic device to continue operating under the redundant system, thereby not only improving the operational reliability of the electronic device, but also ensuring that the electronic device continues to operate after an EMP event occurs; and solving the technical problem that the control system of the existing electromagnetic pulse protection device is insufficiently reliable and resilient, and cannot ensure that it can continue to operate at critical moments.

[0069] In one embodiment of the present application, the electromagnetic pulse protection control method for the electronic device includes: if an EMP event occurs, and then after determining that the EMP event of the target electronic device has been eliminated based on the electromagnetic pulse data obtained in real time, the redundant system operating the target electronic device is controlled to switch to the main system.

[0070] It should be noted that the electromagnetic pulse protection control method for electronic equipment can also use the main system to control the operation of the target electronic equipment again after the EMP event is eliminated.

[0071] Example 2:

[0072] FIG2 is a schematic diagram of the framework of the electromagnetic pulse protection control system of the electronic device described in an embodiment of the present application.

[0073] As shown in Figure 2, an embodiment of the present application provides an electromagnetic pulse protection control system for an electronic device, including an equipment protection module and a monitoring module. The equipment protection module includes a redundant system unit 11, an emergency power-off unit 12, a signal filtering unit 13, a shielding unit 14 and an energy backup unit 15. The monitoring module includes a signal analysis and processing unit 21 and an EMP detection unit 22, a communication unit 23, a system switching unit 24 and a data backup and recovery unit 25 connected to the signal analysis and processing unit 21. The EMP detection unit 22 is connected to the signal filtering unit 13, and the communication unit 23 is connected to the redundant system unit 11, the signal filtering unit 13, the emergency power-off unit 12 and the energy backup unit 15 respectively.

[0074] In the embodiment of the present application, the EMP detection unit 22 can be used to obtain electromagnetic pulse data of the target electronic device from the signal filtering unit 13 in real time, and transmit the electromagnetic pulse data to the signal analysis and processing unit 21.

[0075] It should be noted that the EMP detection unit 22 is used to detect and identify EMP events of intrusion of a target electronic device. The EMP detection unit 22 is also connected to the sensor network and monitoring system of the target electronic device.

[0076] In an embodiment of the present application, the signal analysis and processing unit 21 can be used to process electromagnetic pulse data using the above-mentioned electromagnetic pulse protection control method for electronic equipment, obtain EMP intrusion information of the target electronic equipment, and transmit the EMP intrusion information to the equipment protection module through the communication unit 23.

[0077] It should be noted that the details of the electromagnetic pulse protection control method for electronic equipment have been described in Example 1, and the modules of the electromagnetic pulse protection control system for electronic equipment will not be further described in this example. The signal analysis and processing unit 21 is used to perform real-time analysis of electromagnetic pulse data from intruding target electronic equipment to determine the corresponding signal strength and signal frequency.

[0078] In an embodiment of the present application, the device protection module can be used to cut off the power supply of the target electronic device through the emergency power-off unit 12 in response to EMP intrusion information, switch the main system running the target electronic device to the redundant system through the redundant system unit 11, and provide backup power to the target electronic device through the energy backup unit 15, so that the target electronic device continues to operate with the redundant system.

[0079] In this embodiment of the present application, the signal filtering unit 13 is used to filter intruding EMP signals and reduce their interference effects. The signal filtering unit 13 is connected to the power line and communication line to prevent the transmission of EMP signals. The shielding unit 14 can be used to provide physical shielding for the target electronic device, blocking external EMP radiation from the target electronic device and sealing the target electronic device's interior. The redundant system unit 11 is used to ensure that during an EMP event, the redundant system, a backup system, can control the operation of the target electronic device and enable the target electronic device to perform its critical functions. The redundant system is connected in parallel with the target electronic device's main system. The redundant system unit 11 can work in conjunction with the EMP detection unit 22 to monitor EMP events in real time. The emergency power-off unit 12 is used to quickly cut off power to the target electronic device upon detecting an EMP event to prevent further damage from the electromagnetic pulse. The emergency power-off unit 12 can be connected to the power line and communication unit 23 to achieve a rapid response. The communication unit 23 is used to ensure reliable communication within and outside the target electronic device during an EMP event and provides communication support to the redundant system unit 11, the signal filtering unit 13, the emergency power-off unit 12, and the energy backup unit 15. The data backup and recovery unit 25 can be used to regularly back up system data and restore it when needed to ensure data integrity and availability. The data backup and recovery unit 25 is connected to the redundant system unit 11 and the primary system to ensure synchronized data backup. The energy backup unit 15 is used to provide backup power to ensure that target electronic equipment can continue to operate during an EMP event. The energy backup unit 15 is connected to the primary and redundant systems to provide stable power support.

[0080] In an embodiment of the present application, the electromagnetic pulse protection control system for electronic equipment includes an automatic system recovery module 30. Automatic system recovery module 30 is configured to monitor the status of the target electronic equipment's main system and automatically switch to a redundant system when the target electronic equipment's main system is affected by an EMP. The module then restores the main system after the EMP event is resolved. Automatic system recovery module 30 operates in conjunction with redundant system unit 11, signal analysis and processing unit 21, and data backup and recovery unit 25.

[0081] In this embodiment of the present application, the electromagnetic pulse protection control system of the electronic device effectively blocks external EMP radiation through the shielding unit 14 and signal filtering unit 13, reducing the impact of EMP events on the target electronic device. The signal analysis and processing unit 21 monitors the target electronic device in real time to determine whether an EMP event has occurred, ensuring timely implementation of protective measures. The coordinated operation of the automatic system recovery module 30 and the redundant system unit 11 enables the electromagnetic pulse protection control system of the electronic device to quickly switch to the redundant system when an EMP event occurs, maintaining continuity. After the EMP event is resolved, the electromagnetic pulse protection control system automatically restores the target electronic device to the primary system, reducing the risk of operational interruption. The data backup and recovery unit 25 ensures regular backup and recovery of the target electronic device's data, reducing the risk of data loss. The coordination between the redundant system unit 11 and the automatic system recovery module 30 ensures data integrity and consistency during the switching process. The communication unit 23 ensures the reliability of internal and external communications within the target electronic device during an EMP event. The backup channel and automatic switching function of the communication unit 23 ensure continuous communication. The emergency power-off unit 12 rapidly cuts off power to the target electronic device when an EMP event occurs, minimizing damage to the target electronic device from the electromagnetic pulse and improving its survivability. The signal analysis and processing unit 21 monitors and analyzes whether an EMP event has occurred in the target electronic device, providing real-time EMP event information to personnel monitoring the target electronic device, enabling them to take appropriate action. The data backup and recovery unit 25 automatically executes data backup and recovery procedures, reducing the workload of personnel monitoring the target electronic device and ensuring continuous data availability. The coordinated operation and automated functions of the various units in the EMP protection control system enable the system to rapidly respond to an EMP event without requiring extensive human intervention. The EMP protection control system integrates multiple units that work together to provide multi-layered protection and automation, significantly improving the reliability, resilience, and recovery capabilities of the target electronic device. This helps ensure continued stable operation of the target electronic device during an EMP event and reduces the risk of interruption and data loss caused by an EMP event.

[0082] It should be noted that the electromagnetic pulse protection control system of this electronic equipment integrates multiple units, which helps to effectively take corresponding protective measures in response to EMP incidents in target electronic equipment.

[0083] In one embodiment of the present application, the EMP detection unit 22 includes an electromagnetic detection element, a signal amplifying element connected to the electromagnetic detection element, and a signal conversion element connected to the signal amplifying element; the electromagnetic detection element is used to collect electromagnetic radiation from the target electronic device and convert the electromagnetic radiation into an analog electrical signal; the signal amplifying element is used to amplify the analog electrical signal to obtain an amplified analog signal; and the signal conversion element is used to convert the amplified analog signal into electromagnetic pulse data of a digital signal.

[0084] It should be noted that the electromagnetic detection element can be an electromagnetic sensor, which can be an antenna or an induction coil. The signal amplification element can be an amplifier. The electromagnetic sensor is used to capture ambient electromagnetic radiation and convert it into an electrical signal. The signal amplification element is used to amplify the weak electrical signal from the electromagnetic detection element for further processing. The signal conversion element may include an analog-to-digital converter (ADC) and a digital signal processor (DSP) to convert the analog electrical signal into digital electromagnetic pulse data. In this embodiment, the EMP detection unit 22 also includes a signal connection interface connected to the signal conversion element. The signal connection interface is provided on the monitoring module and transmits electromagnetic pulse data. The EMP detection unit 22 captures ambient electromagnetic radiation (including radiation from the EMP event) through the electromagnetic sensor. The captured signal is transmitted to the amplifier to increase the signal amplitude, and then the signal is digitized and sent to the signal analysis and processing unit 21.

[0085] In one embodiment of the present application, the signal analysis and processing unit 21 includes a spectrum analysis subunit, an intensity analysis subunit, a preliminary judgment subunit, and an identification subunit.

[0086] In the embodiment of the present application, the spectrum analysis subunit is used to perform spectrum analysis on the electromagnetic pulse data to obtain the signal frequency corresponding to the electromagnetic pulse data.

[0087] It should be noted that spectrum analysis is performed on the sampled electromagnetic pulse data to determine the frequency components of the signal and obtain the signal frequency. Common spectrum analysis methods include Fourier transform or fast Fourier transform (FFT).

[0088] In the embodiment of the present application, the strength analysis subunit is used to measure the signal amplitude of the electromagnetic pulse data to obtain the signal strength corresponding to the electromagnetic pulse data;

[0089] It should be noted that the strength analysis subunit determines the signal strength by measuring the amplitude of the electromagnetic pulse data. The amplitude of the electromagnetic pulse data can be measured using methods such as root mean square (RMS) or peak amplitude.

[0090] In the embodiment of the present application, the preliminary judgment subunit is used to compare the signal strength and signal frequency with the corresponding specific threshold value to obtain a preliminary judgment result.

[0091] It should be noted that the preliminary judgment subunit can detect signal frequency and signal strength. In threshold detection, predefined thresholds or standards are used to determine whether the monitored signal frequency and signal strength have reached a dangerous level or require action. These thresholds can be set based on different characteristics of the EMP signal, including frequency and intensity. The preliminary judgment subunit can include the following aspects: First, the specific threshold is a frequency threshold, which defines the distribution of the EMP signal at different frequencies in the EMP data. If the frequency of the EMP signal detected in the EMP data exceeds the set frequency threshold, the preliminary judgment subunit may determine that the EMP data contains an EMP event. Second, the specific threshold is an intensity threshold, which sets a threshold for the intensity of the EMP signal or the energy level of the electromagnetic radiation in the EMP data. When the intensity of the EMP signal detected in the EMP data reaches or exceeds the set intensity threshold, the preliminary judgment subunit may determine that a strong EMP impact exists and that appropriate measures are required. The specific thresholds can be set as needed to ensure that the preliminary judgment subunit has appropriate sensitivity and accuracy for different types of EMP events. Once the frequency and intensity of the monitored EMP signal exceeds the set specific threshold, the preliminary judgment subunit can trigger corresponding protection and switching measures to ensure the safe and reliable operation of the electromagnetic pulse protection control system of the electronic equipment and the target electronic equipment.

[0092] In an embodiment of the present application, the identification subunit is used to compare the electromagnetic pulse data with the known EMP event data in the database based on the preliminary determination result that an EMP event may have occurred, and determine the EMP intrusion information of the target electronic device; wherein the EMP intrusion information includes whether an EMP event has occurred in the target electronic device and whether an EMP event has not occurred in the target electronic device.

[0093] It should be noted that the identification subunit determines whether the signal of the currently captured electromagnetic pulse data matches a known EMP event. If there is a signal that matches the electromagnetic pulse data, the identification subunit will determine that an EMP event has occurred in the target electronic device.

[0094] In this embodiment of the present application, the signal analysis and processing unit 21 also includes a data storage subunit and an alarm subunit. The data storage subunit is used to record and store the monitored electromagnetic pulse data for further analysis and subsequent reporting. The alarm subunit is used to issue an alarm based on the preliminary determination that an EMP event may have occurred.

[0095] In one embodiment of the present application, the emergency power off unit 12 is configured to immediately issue a power cutoff signal upon receiving a signal indicating an EMP event has occurred in a target electronic device. This can be achieved by controlling a power switching device (such as a relay or switch). Furthermore, upon receiving the power cutoff signal, the emergency power off unit 12 can quickly operate a switch on the power line to disconnect the power from the target electronic device. This can be achieved by installing an electronic switch or relay on the power line. The emergency power off unit 12 continues to receive EMP intrusion information to ensure that the power remains disconnected until the EMP event is resolved. If the EMP event persists, the emergency power off unit 12 prevents power from being restored. The emergency power off unit 12 can also allow power to be restored once the EMP event is resolved. This can be achieved by reclosing the switch on the power line. The emergency power off unit 12 may provide both automatic and manual control options. In automatic mode, the emergency power off unit 12 automatically cuts off and restores power upon detection of an EMP event. In manual mode, the operator can manually control the power status. When the emergency power-off unit 12 cuts off power, it triggers an alarm, notifying relevant parties, such as system administrators or maintenance personnel. This notification can be achieved through the communication unit 23. The primary task of this emergency power-off unit 12 is to rapidly cut off power during an EMP event to minimize damage to equipment from the electromagnetic pulse. This requires highly reliable electronic switching and monitoring capabilities to ensure that power is cut off extremely quickly and that normal operation is restored after the EMP event is lifted.

[0096] In one embodiment of the present application, the communication unit 23 includes:

[0097] Communication interface, used to connect with other modules or units, including signal filtering unit 13 and signal analysis and processing unit 21; the communication interface can be implemented by cables, connectors or wireless communication equipment;

[0098] Communication equipment, which is used to equip the target electronic device with appropriate communication equipment to ensure internal and external communication; the communication equipment may include wired communication (such as Ethernet), wireless communication (such as Wi-Fi, cellular network), satellite communication, and other communication methods;

[0099] Communication line protection, which uses appropriate hardware and techniques to protect communication lines from EMP events; communication line protection may include the use of electromagnetic shielding, power line filters, and other devices;

[0100] Signal retransmission and recovery, which is used to implement signal retransmission and recovery mechanisms to ensure data integrity and availability. When an EMP event causes communication interruption, the communication unit 23 can use signal retransmission and recovery to try to resend the lost data or establish a new communication link.

[0101] Communication protocols and collaborative work, used to ensure that the communication unit 23 uses compatible communication protocols and standards with other modules to facilitate collaborative work; communication protocols may include TCP / IP, Modbus, CAN, etc.;

[0105] Emergency Communications Plan to develop and implement an emergency communications plan to ensure communications with key stakeholders (e.g., rescue teams, management) are possible during an EMP event.

[0106] It should be noted that the design and operation of the EMP protection control system of the electronic device, through the communication unit 23, requires a high degree of reliability and resilience to ensure that internal and external communications of the EMP protection control system of the electronic device can be maintained during an EMP event. The EMP protection control system of the electronic device employs multiple means and backup measures to increase the stability and availability of communications.

[0107] In one embodiment of the present application, the data backup and recovery unit 25 includes:

[0108] The data backup plan subunit is used to formulate a data backup plan and determine the backup frequency and storage strategy. Usually, data will be backed up regularly to a secure storage medium such as a hard drive, tape, or cloud storage.

[0109] The data backup device subunit is configured to be equipped with appropriate data backup devices, such as a backup server, a storage array, or a backup tape drive, for storing backup data. The data backup device should be connected to the redundant system unit 11 and the main system to ensure synchronization of the backup data.

[0110] The automatic backup program subunit is used to implement an automatic backup program to perform data backups on a regular basis. The backups can be full, incremental, or differential, depending on the needs. The backup program should work in conjunction with the primary system to ensure that critical system functions are not interrupted during the backup.

[0111] A backup data storage subunit, which is used to store the backup data in a secure location to prevent it from any physical or electromagnetic threats; it can be an off-site storage, an offline storage or a remote cloud storage;

[0112] The data recovery procedure subunit is used to implement data recovery procedures to quickly restore data when needed. The data recovery procedure subunit may involve operations such as restoring data from backup media or reconnecting to a backup server. The data recovery procedure should work in conjunction with the primary system and redundant system units 11 to ensure a smooth recovery process.

[0113] A data integrity check subunit is used to periodically verify the integrity of the backup data to ensure that the backup is usable and not damaged; the data integrity check subunit can be completed by checksum data signature or other verification methods;

[0114] The backup and recovery test subunit is used to perform regular backup and recovery tests, simulating data loss situations to ensure the effectiveness of backup and recovery procedures. The backup and recovery test subunit facilitates rapid recovery in actual data loss situations.

[0115] The data security subunit is used to protect the security of backup data by adopting encryption and access control measures to prevent unauthorized access and data leakage.

[0116] It should be noted that the design and operation of the EMP protection control system of the electronic device, through the data backup and recovery unit 25, requires a high degree of reliability and security to ensure the integrity and availability of the EMP protection control system data of the electronic device. Data backup and recovery is a key disaster recovery strategy that helps reduce the risk of data loss and quickly restore the target electronic device's redundant system or primary system when needed.

[0117] In one embodiment of the present application, the system switching unit 24 includes a main system monitoring subunit, a redundant system monitoring subunit, a system switching subunit and a release monitoring subunit; the main system monitoring subunit is used to monitor the first working state of the main system in the target electronic device; the redundant system monitoring subunit is used to monitor the second working state of the redundant system in the target electronic device; the system switching subunit is used to issue a first switching instruction to switch the main system that controls the operation of the target electronic device to the redundant system based on the EMP intrusion information that an EMP event has occurred, the first working state is abnormal and / or the second working state is normal; the release monitoring subunit is used to issue a second switching instruction to switch the redundant system that controls the operation of the target electronic device to the main system after the EMP event occurs and the EMP event of the target electronic device is eliminated based on the electromagnetic pulse data obtained in real time; wherein the equipment protection module is also used to switch between the redundant system and the main system of the target electronic device according to the first switching instruction and the second switching instruction.

[0118] It should be noted that the primary function of the system switching unit 24 is to monitor the status of the primary system. When the primary system is affected by an EMP event, it automatically switches to the redundant system and restores the primary system after the EMP event is resolved. The primary system monitoring subunit is used to monitor the primary system's first operating state, which includes the operational status of hardware, software, network connectivity, and other aspects. Monitoring the primary system's first operating state can be achieved in real time using monitoring sensors, state detection algorithms, and the like. The system switching subunit works in conjunction with the signal analysis and processing unit 21 to obtain information about the status and intensity of the EMP event. This helps the system switching unit 24 determine when to trigger the system switching subunit. The redundant system monitoring subunit is also used to simultaneously monitor the redundant system's second operating state to ensure it is ready to take over the primary system's functions. This second operating state monitoring of the redundant system may include hardware status, data synchronization status, and the like. When switching conditions (e.g., EMP intrusion information indicating an EMP event has occurred, the first operating state is abnormal, and / or the second operating state is normal) are met, the system switching subunit issues a first switching instruction to switch the primary system controlling the operation of the target electronic device to the redundant system. The system switching process should be fast and reliable to ensure continuity between the target electronic device's primary system and the redundant system. The system switching unit 24 also includes a redundant system takeover subunit. Once the switch is complete, the redundant system takeover subunit assumes the functions of the primary or redundant system, allowing the corresponding redundant or primary system to continue operating normally and provide required services. A release monitoring subunit is used to continuously monitor the status of the EMP event to determine when the EMP event has been resolved. Once the EMP event has been resolved, the release monitoring subunit, in conjunction with the device protection module, triggers the restoration of the primary system. The system switching unit 24 also includes a primary system recovery subunit: Once the EMP event has been resolved, the primary system recovery subunit triggers the primary system's recovery process. This includes operations such as power restoration, data synchronization, and configuration restoration. The system switching unit 24 also includes a performance monitoring and reporting subunit. After the switch and recovery process, the performance monitoring and reporting subunit monitors the performance of the primary and redundant systems and generates performance reports for reference by system administrators and maintenance personnel. The design and operation of the system switching unit 24 for this electronic device's electromagnetic pulse protection control system requires high reliability and real-time performance to ensure rapid switchover to the redundant system during an EMP event and restoration of the primary system after the EMP event has been resolved. The system switching unit 24 needs to work in conjunction with other key units to achieve automatic switching and recovery processes.

[0119] In one embodiment of the present application, the redundant system unit 11 includes a system parallel subunit, a backup system activation subunit and a resynchronization subunit; the system parallel subunit is used to connect the redundant system of the target electronic device in parallel with the main system; the backup system activation subunit is used to trigger the activation of the redundant system of the target electronic device for an EMP event according to the EMP intrusion information; the resynchronization subunit is used to automatically synchronize the corresponding data and program recovery of the target electronic device after switching between the redundant system and the main system of the target electronic device.

[0120] It should be noted that the redundant system has the same functions and performance as the main system of the target electronic device, ensuring hardware and software compatibility between the redundant system, the backup system, and the main system for seamless transition during switching. The redundant system unit 11 connects the redundant system of the target electronic device in parallel with the main system through the system parallel sub-unit to ensure that the two systems can operate synchronously in real time, facilitating control of switching between the main system and the redundant system. When the redundant system unit 11 receives information from the communication unit 23 regarding an EMP event occurring in the target electronic device or a failure in the main system, the backup system activation sub-unit is activated, triggering activation of the redundant system. After the redundant system unit 11 switches between the main system and the redundant system through the resynchronization sub-unit, it ensures that data synchronization and recovery procedures are automatically performed, ensuring that the redundant system maintains synchronization with the main system after taking over control of the operation of the target electronic device, allowing for a smooth transition.

[0121] In this embodiment of the present application, the redundant system unit 11 also includes a continuous monitoring subunit and a report generation subunit. The continuous monitoring subunit is configured to continue monitoring the status of the primary system and the EMP event in the target electronic device after the redundant system takes over control of the target electronic device. When the primary system returns to normal and the EMP event is resolved, it can trigger a switchover from the redundant system operating the target electronic device back to the primary system. The report generation subunit is configured to monitor and evaluate the performance of the target electronic device after the EMP event is resolved to ensure normal operation and to generate a performance report for reference by administrators and maintenance personnel of the target electronic device.

[0122] It should be noted that the design and operation of the redundant system unit 11 require a high degree of reliability and real-time performance. The successful operation of the redundant system unit 11 depends on its ability to quickly and reliably identify EMP events and switch to the redundant system to ensure the continuity and reliability of the electromagnetic pulse protection control system of the electronic equipment.

[0123] In one embodiment of the present application, the signal filtering unit 13 includes a signal input subunit, a filtering element and a signal output subunit connected in sequence; the signal input subunit is used to connect the target electronic device to the power line and the communication line; the filtering element is used to prevent the high-frequency signals of the power line and the communication line from entering the target electronic device to obtain a filtered signal; the signal output subunit is used to input the filtered signal into the target electronic device.

[0124] It should be noted that the signal input subunit can be a signal interface used to connect the target electronic device to power lines and communication lines to intercept intruding EMP signals. The filtering element includes a low-pass filter to prevent the propagation of high-frequency signals. The signal output subunit includes connectors, terminal blocks, etc., and is used to distribute the filtered signal to the power lines and communication lines of the target electronic device. In this embodiment, the filtering element can be constructed from an inductor, capacitors, and resistors to form a filter circuit. The design of the filter circuit will depend on the spectral characteristics of the EMP signal to be filtered. Typically, EMP signals are high-frequency signals, so the filter is usually designed as a low-pass filter to prevent the propagation of high-frequency signals.

[0125] In the embodiment of the present application, the signal filtering unit 13 further includes a monitoring and control circuit, which is used to monitor the filtering effect and take measures when necessary.

[0126] It should be noted that the monitoring and control circuit may include the use of electronic switching devices, such as components such as diodes, to turn filtering on or off according to signal conditions. The signal filtering unit 13 is connected to the power line and the communication line. The invading EMP signal enters the signal filtering unit 13, and the filtering elements of the signal filtering unit 13 filter the EMP signal to weaken or block the high-frequency components within its spectrum range. The filtered signal is transmitted to the power line and communication line of the target electronic device. The filtered signal enters the target electronic device and is not affected by the EMP. The goal of this signal filtering unit 13 is to protect the target electronic device from the influence of the invading EMP signal and reduce its interference effect. The design and performance of the filtering elements are critical to the effectiveness of the module because they determine which frequency ranges of the EMP signals will be filtered out. The signal filtering unit 13 can be customized as needed to adapt to EMP events in different spectrum ranges.

[0127] In one embodiment of the present application, the shielding unit 14 includes a shielding shell for shielding EMP signals from entering the target electronic device. The shielding shell is provided with a seal, a grounding wire, a shielding pad and a shielding grounding ring. The grounding wire is used to electrically connect the shielding shell to the ground. The shielding pad is arranged on the inner wall surface of the shielding shell. The shielding grounding ring is arranged at the grounding connection point of the shielding shell. The seal is used to seal the shielding shell.

[0128] It should be noted that the shielding enclosure is an enclosure made of a conductive material, such as metal (e.g., aluminum, steel, copper) or other specially designed materials. The purpose of the shielding enclosure is to provide physical shielding for the target electronic device, isolating external EMP radiation from the outside. The seal is used to tightly seal the shielding enclosure, ensuring the tightness of the shielding enclosure to prevent electromagnetic leakage to the target electronic device and ensure that no EMP signals can penetrate the interior of the target electronic device. The seal is provided with a connector, which is typically connected to other units, such as the signal filtering unit 13 and the EMP detection unit 22. The grounding wire ensures a good electrical connection between the shielding enclosure and the ground, thereby directing the electromagnetic pulse energy underground rather than into the interior of the target electronic device. The shielding pad is made of a special shielding material and is typically located inside the shielding enclosure to further reduce the penetration of EMP signals into the target electronic device. The shielding grounding ring is a metal ring placed near the ground connection point of the shielding enclosure to provide an additional grounding connection. The shielding unit 14 tightly encloses the target electronic device with the shielding enclosure, ensuring that no EMP signals can pass through the shielding enclosure and into the interior of the target electronic device. A good electrical connection is ensured between the shielding housing and the ground through a grounding wire so that the electromagnetic energy of the EMP signal is guided underground. Where necessary, shielding pads and shielding grounding rings further enhance the shielding performance of the shielding housing. The shielding housing and connectors are connected to other units to ensure that the entire electromagnetic pulse protection control system of the electronic equipment is protected. The goal of the shielding unit 14 is to provide physical shielding to isolate external EMP radiation to the outside, thereby protecting the target electronic equipment from the impact of the EMP event. The design and manufacture of the shielding housing need to take into account the conductivity of the material, the reliability of the connection, and the sealing to ensure an effective shielding effect.
