Description

Technical Field

[0001] This invention belongs to the field of information security protection technology, and in particular relates to a remote monitoring and scheduling control platform for signal shielding equipment. Background Technology

[0002] In information security protection systems for classified areas, remote monitoring and dispatching control platforms for signal jamming equipment have become one of the core infrastructures. Related technologies have achieved initial hardware and software architecture construction and the implementation of basic control functions. From a hardware perspective, existing technologies generally include fixed jamming base stations, simple mobile jamming modules, basic biometric data collectors, GPS positioning sensors, and data storage servers, enabling frequency band jamming and basic status monitoring in specific areas. From a software perspective, they support data interaction using conventional encrypted communication protocols, possess single-dimensional personnel qualification verification, fixed-mode jamming strategy distribution, and local storage capabilities for basic control data. Some platforms can also remotely start / stop and adjust the power of jamming equipment. Preliminary applications have been completed in scenarios such as single classified rooms and small classified areas, providing basic technical support for the protection of classified signals.

[0003] However, the existing signal shielding control platforms fall significantly short of the comprehensive, precise, and intelligent requirements for classified information protection. First, they cannot achieve deep integration of personnel qualifications, carrier status, and shielding strategies, making it difficult to form a closed-loop protection mechanism based on basic verification. Second, they lack adaptability to multiple scenarios, failing to meet the low-radiation shielding requirements of precision testing scenarios or provide differentiated protection for mobile carriers along different road sections. Third, they lack precise side-channel eavesdropping identification and targeted interference capabilities, making comprehensive shielding susceptible to disruptions to normal communication. Fourth, they lack a multi-dimensional risk-linked decision-making system, resulting in fragmented protection strategies across different areas. Fifth, their data traceability system is incomplete, lacking encrypted closed-loop storage and multi-dimensional auditing capabilities, making it difficult to meet the full-process control requirements of complex classified scenarios. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a remote monitoring and scheduling control platform for signal shielding equipment, which solves the problems of the prior art, such as the decoupling of qualification carriers from shielding, poor adaptability to multiple scenarios, lack of accurate anti-theft and risk linkage, and imperfect traceability system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A remote monitoring and dispatching control platform for signal jamming equipment includes a central control hub and four linked sub-modules that interact with the central control hub via an encrypted dedicated communication protocol. The four linked sub-modules are a classified entity access control linkage module, a multi-scenario jamming mode adaptation module, a precise anti-espionage jamming module, and a full-link monitoring and tracing module. The central control unit incorporates a multi-dimensional classified risk decision-making engine. This engine integrates a weighted scoring algorithm, the core calculation formula of which is: Where S is the comprehensive risk value and its value ranges from 0 to 10, and i=1 corresponds to the personnel qualification risk coefficient. i=2 corresponds to the carrier's risk factor for classified information. Electromagnetic risk coefficient for scenario i=3 i=4 corresponds to the risk coefficient of the eavesdropping signal. Each risk coefficient ranges from 0 to 10. The weight coefficients for each risk dimension and satisfying , The value range is 0 to 1, and those skilled in the art can adjust the weight coefficient according to the actual classified scenario; the decision engine automatically generates a matching shielding strategy based on the range of the comprehensive risk value S. When S≥8, the highest level of full-band strong shielding is triggered, which can achieve a classified signal blocking rate of over 99%. When 3≤S<8, medium-level directional shielding is triggered. When S<3, basic-level civilian frequency band shielding is triggered. Each linkage sub-module is equipped with a protocol conversion interface, which supports the connection with the existing classified management system. The interface is compatible with TCP / IP, RS485, and LoRa communication standards. The classified entity access control and shielding linkage module is used to bind personnel qualifications, carrier transfer and shielding permissions; the multi-scenario shielding mode adaptation module is used to adapt the shielding strategy to fixed precision scenarios and mobile carrier scenarios; the precise anti-espionage shielding module is used to identify and target the risk of side-channel espionage; the full-link monitoring and traceability module is used to collect, encrypt and store and trace the source of full-process control data.

[0006] Preferably, the classified entity access control linkage module includes a personnel qualification verification unit and a carrier transfer control unit; The personnel qualification verification unit connects to the biometric database of classified personnel and employs a dynamic feature point comparison algorithm. The core calculation formula of the dynamic feature point comparison algorithm is as follows: Where M is the feature matching degree, The number of feature points that were successfully matched. The total number of feature points to be compared is typically between 20 and 50. Verification is considered successful when M is not less than 99.9%. This matching accuracy can control the biometric false positive rate to within 0.01%, and the verification response time is no more than 200ms. A mapping table of personnel confidentiality qualification levels and shielding permissions is pre-stored. Qualification levels are divided into three levels: core, important, and ordinary, corresponding to different area shielding permissions. An unqualified personnel identification trigger mechanism is configured. When an unauthorized person is detected approaching a confidential area at a distance of no more than 5 meters, a local emergency strong shielding is triggered, and the local operation permission of the shielding device is locked. The carrier circulation control unit links the logistics GPS positioning system with the carrier smart lock, and presets carrier storage and retrieval shielding trigger logic. When the carrier is retrieved, a full-band strong shielding command is sent to the shielding equipment in the core area of ​​the secure room. The shielding frequency band covers 100MHz to 6GHz, and the power is not less than 30dBm. This power parameter is adapted to the high-level security requirements of the core area of ​​the secure room, and the duration is configurable. When the carrier is stored and locked, it switches to the normal shielding mode, which only shields civilian communication frequency bands, and the power is not higher than 15dBm. The built-in carrier anomaly monitoring algorithm locks the shielding equipment within 50 meters of the secure room and uploads the abnormal data when the carrier is not returned within the specified period or the storage and retrieval record is missing.

[0007] Preferably, the multi-scenario shielding mode adaptation module includes a fixed precision scenario adaptation unit and a mobile carrier scenario adaptation unit; The fixed precision scene adaptation unit is equipped with an electromagnetic environment baseline acquisition sensor, which acquires data once per second, and the baseline data storage period is no less than one year. It has preset silent shielding mode parameters, ensuring that the electromagnetic radiation of the shielding equipment itself is no higher than 5dBμV / m and covers the frequency band from 10kHz to 1GHz. At the same time, it initiates directional low-power interference with a power no higher than 10dBm and an interference direction error no greater than 5 degrees. It has a built-in anechoic chamber hidden danger monitoring mechanism. When the width of the shielding door gap is no less than 5 mm or the filter signal attenuation is less than 60dB, it locks the start permission of the test equipment in the anechoic chamber and simultaneously schedules a backup shielding node to fill the gap. The replacement response time is no more than 2 seconds. The mobile carrier scene adaptation unit adopts a trajectory region linkage algorithm, and the core calculation formula of the trajectory region linkage algorithm is: Where D is the straight-line distance between the real-time position of the vehicle and the boundary of the preset road segment, and (x, y) are the real-time coordinates of the vehicle. , The system uses preset road segment boundary reference coordinates and preset threshold values ​​typically ranging from 5 to 20 meters. When D is less than the preset threshold, it determines that the carrier has entered the corresponding road segment and triggers a matching shielding strategy. This algorithm can achieve a road segment shielding mode switching response time of no more than 1 second. Public transport road segments trigger full-band strong shielding, covering 100MHz to 6GHz, with a power of no less than 25dBm. This power parameter is adapted to the portable power supply and protection balance requirements of mobile carriers. Confidential handover road segments switch to directional weak shielding, shielding only the civilian communication frequency band from 800MHz to 2600MHz, while retaining the 350MHz police frequency band and the 400MHz emergency frequency band. An abnormal state triggering logic is configured. When unauthorized unlocking of the cabinet door is detected or the strength of high-risk eavesdropping signals in the surrounding area is no less than -40dBm, the on-board shielding module is triggered to emergency silent mode, and the carrier's real-time location is pushed to the central control hub, with a positioning error of no more than 10 meters.

[0008] Preferably, the precision anti-eavesdropping shielding module includes a side-channel signal identification unit and a targeted shielding scheduling unit; The side-channel signal identification unit integrates a weak electromagnetic feature acquisition sensor, capable of capturing weak electromagnetic signals in the 10kHz to 1GHz frequency band with a sensitivity not exceeding -100dBm. It supports the identification of keyboard key current fluctuations and chip clock frequency fluctuations. A built-in side-channel signal classification algorithm, based on a convolutional neural network model, is included, with the loss function calculated as follows: Where n is the number of samples, which typically ranges from 1000 to 5000 groups. For the true labels of the samples, For model prediction labels, those skilled in the art can optimize the sample library according to the actual types of espionage signals; the signal recognition accuracy of this algorithm is no less than 98%, and the false alarm rate is no more than 0.5%, which can effectively distinguish between normal office electromagnetic signals and espionage risk signals; The targeted shielding scheduling unit pre-stores the deployment location information of miniature directional shielding nodes. When a side-channel eavesdropping risk is detected, a triangulation algorithm is used to locate the signal source with a positioning error of no more than 1 meter. This positioning accuracy ensures that the interference range of the miniature directional shielding nodes accurately covers the eavesdropping source, avoiding interference with normal communications in the surrounding area. Precise interference commands are sent to the miniature directional shielding nodes in the target area, with the interference frequency band matching the eavesdropping signal frequency band. The interference range is controlled within a micro-area of ​​2 meters × 2 meters × 2 meters, and the power does not exceed 8 dBm. The side-channel signal source, strength, shielding handling time, and parameters are automatically recorded to form a standardized anti-eavesdropping handling log.

[0009] Preferably, the end-to-end monitoring and traceability module includes a data acquisition unit and a data storage and traceability unit; The data acquisition unit collects operational data from each module in real time, including records of personnel access shielding status, carrier access shielding mode switching logs, multi-scenario shielding parameter adjustment trajectories, side-channel eavesdropping protection and handling ledgers, and logistics transportation electromagnetic environment and positioning data. The data acquisition granularity is accurate to the second level. The data storage and traceability unit adopts a distributed encrypted storage architecture. Data is verified by the SM3 hash algorithm and encrypted by the SM4 algorithm before being stored. It has a built-in traceability query interface that supports searching for corresponding blocked and controlled data by time, personnel, carrier, and scenario. The query response time is no more than 3 seconds. It supports the generation of standardized confidentiality audit reports, and the report format is compatible with Excel and PDF formats.

[0010] Preferably, the encrypted dedicated communication protocol used between the central control unit and each linked sub-module is the national cryptographic SM4 protocol, with a communication latency of no more than 50ms; the strategy output response time of the multi-dimensional classified risk decision engine is no more than 100ms.

[0011] Preferably, in the carrier access shielding triggering logic, the default duration of full-band strong shielding is 5 minutes; in the carrier anomaly monitoring algorithm, the preset time limit for carriers not returned after the expiration date can be configured in 1-hour increments within the range of 1 to 72 hours, with a default expiration time limit of 24 hours.

[0012] Preferably, the anti-espionage handling ledger supports encrypted export based on the SM4 algorithm, and the ledger has a built-in audit verification code. The verification code is composed of the ledger generation timestamp, data hash value and operator identity identifier, which can realize the verification and audit query of ledger tampering.

[0013] Preferably, the biometric database of classified personnel in the personnel qualification verification unit includes three types of biometric data: fingerprint, face, and iris. It adopts a dual-feature cross-verification mechanism, which means that when personnel are granted access, they must simultaneously complete the matching of two types of biometric features. Only after the verification is passed can the corresponding blocking permission be triggered. The unqualified personnel identification trigger mechanism is also linked to the video surveillance system, which can simultaneously capture real-time images of unauthorized personnel and bind and upload them with abnormal alarm information. This linkage mechanism can realize the simultaneous completion of personnel identity verification and abnormal behavior evidence collection, and improve the traceability efficiency of access control in classified areas.

[0014] Preferably, the fixed precision scene adaptation unit is also equipped with an automatic electromagnetic environment baseline calibration mechanism. The calibration cycle can be customized. During the calibration process, the deviation value is calculated by comparing the historical baseline data with the real-time acquired data. The deviation value is calculated using the following formula: ,in This is the electromagnetic radiation deviation value. These are the electromagnetic radiation values ​​collected in real time. The historical baseline electromagnetic radiation value, when When the interference phase and frequency parameters of the shielding equipment are not less than 3dBμV / m, the calibration mechanism automatically corrects the interference phase and frequency parameters of the shielding equipment. This calibration mechanism can ensure the stability of the electromagnetic environment in the anechoic chamber and avoid the impact of environmental changes on the accuracy of precision testing. The box-mounted shielding module of the mobile carrier scenario adaptation unit integrates a rechargeable lithium battery and a solar auxiliary power supply component. The rated capacity of the lithium battery is not less than 10000mAh and the conversion efficiency of the solar component is not less than 20%. It can ensure that the box-mounted shielding module can work continuously for not less than 12 hours without an external power supply. The central control unit can monitor the remaining power of the box-mounted shielding module in real time and automatically push a low power alarm when the power is not higher than 20%.

[0015] The technical effects and advantages of the remote monitoring and dispatching control platform for signal shielding equipment of the present invention are as follows: 1. This invention achieves precise binding between the qualifications of entities handling classified information and the shielding strategy. Relying on a dual biometric cross-verification mechanism and carrier flow control logic, it deeply links personnel's confidentiality qualifications, the classified status of carriers, and shielding permissions, eliminating the risk of classified information access caused by unqualified personnel. At the same time, it realizes automatic switching of shielding strategies throughout the entire process of carrier access, solving the problem of the disconnect between personnel permissions and protection strategies in traditional platforms, and significantly improving the basic protection security of classified areas and carriers.

[0016] 2. This invention achieves adaptive adaptation of shielding modes across multiple scenarios. For fixed precision scenarios, the silent shielding mode and automatic electromagnetic baseline calibration mechanism effectively block classified signals while avoiding interference from the electromagnetic radiation of the shielding equipment itself to precision testing. For mobile carrier scenarios, the invention utilizes a trajectory area linkage algorithm to achieve differentiated shielding for different road sections, and a solar-assisted power supply component ensures endurance when no external power source is available, meeting the mobile protection needs of cross-regional logistics transportation and balancing protection effectiveness with scenario adaptability.

[0017] 3. This invention possesses precise side-channel eavesdropping targeted protection capabilities. The signal classification algorithm based on convolutional neural networks can efficiently distinguish between normal office signals and eavesdropping risk signals. Combined with meter-level precision signal source localization and micro-area targeted interference, it achieves 99.94% blocking of eavesdropping signals while avoiding the impact of traditional full-area shielding on normal office communications, filling the technological gap in traditional platforms lacking precise anti-side-channel eavesdropping capabilities.

[0018] 4. This invention constructs a comprehensive intelligent linkage control system for classified information risks. The weighted scoring algorithm of the central control unit can integrate multi-dimensional risk data on personnel, carriers, scenarios, and espionage signals, automatically generate matching shielding strategies, realize the organic integration of multi-scenario protection strategies, solve the drawbacks of fragmented multi-area protection strategies in traditional platforms, and improve the overall coordination and accuracy of classified information protection.

[0019] 5. This invention forms a closed-loop control system with end-to-end encryption and traceability. Through distributed encrypted storage and a multi-dimensional traceability query mechanism, it achieves second-level collection, encrypted storage, and rapid auditing of control data, ensuring data integrity and security, meeting the audit and traceability requirements of classified fields. At the same time, the national cryptographic SM4 protocol ensures the confidentiality of command transmission and data interaction, preventing information leakage during transmission.

[0023] refer to Figure 1 This invention provides a remote monitoring and scheduling control platform for signal shielding equipment. Its hardware architecture includes a central control hub, four types of sub-module terminals, a shielding equipment cluster, and supporting sensing devices. The central control hub handles global decision-making and command issuance. The four types of sub-module terminals are: a shielding linkage terminal for classified entities, a multi-scenario shielding mode adaptation terminal, a precise anti-espionage shielding terminal, and a full-link monitoring and traceability terminal. The shielding equipment cluster includes fixed shielding base stations, box-mounted shielding modules, and miniature directional shielding nodes. Supporting sensing devices include biometric collectors, GPS locators, electromagnetic environment sensors, and spectrum collectors. At the software level, encrypted communication between each terminal and the central control hub is achieved through the national cryptographic SM4 protocol. Built-in core algorithms such as weighted scoring algorithms and dynamic feature point comparison algorithms can automatically generate appropriate shielding strategies based on different classified scenarios.

[0024] Example 1 This embodiment provides a remote monitoring and scheduling control platform for signal shielding equipment, used for access control and shielding linkage management of classified and secure storage facilities. Specific implementation details include: Purpose of implementation: Addressing the pain points of traditional classified storage rooms, such as the disconnect between personnel qualification verification and shielding strategies, the susceptibility to signal leakage during the transfer of materials, and the inability to quickly trace abnormal materials, this solution achieves precise linkage between personnel access qualification verification, classified material access procedures, and shielding strategies. It also enables rapid alarm and evidence collection for abnormal personnel and materials, thus strengthening the classified protection line in the core area of ​​the classified storage room.

[0025] Initial setup: In the personnel qualification verification unit of the classified entity access control linkage terminal, the unit's classified personnel biometric database is accessed. This database contains three types of biometric data: fingerprint, face, and iris. The pre-stored feature point dynamic comparison algorithm parameters are: the total number of feature points to be compared is 30, and the feature matching degree judgment threshold is 99.9%. At the same time, a mapping relationship between personnel confidentiality qualification and shielding authority is established. Core qualified personnel can trigger full-band shielding in the core area of ​​the confidential room, important qualified personnel can only trigger targeted shielding in the buffer zone, and ordinary qualified personnel have no qualification to access the core area or adjust shielding authority.

[0026] The carrier transfer control unit and the intelligent secure cabinet have completed protocol integration. The intelligent secure cabinet is equipped with cabinet door open / close sensors and lock status sensors, which can provide real-time feedback on carrier storage and retrieval operations and double-person double-lock verification status. The preset monitoring time limit for carriers not returned within the time limit is 24 hours. The default duration of strong shielding of the core area across the entire frequency band after the carrier is taken out is 5 minutes. The area within 50 meters around the secure room is designated as an abnormal control zone locked by the shielding equipment.

[0027] The unauthorized personnel identification trigger mechanism is linked to the video surveillance system around the confidential room, and the trigger distance for unauthorized personnel approaching the core area is set to 5 meters.

[0028] Control process: A key personnel with access to classified information applied to enter the core area of ​​the secure room. Simultaneously, a dual-feature cross-verification of facial and iris features was completed. The system counted 30 successfully matched feature points, achieving a feature matching rate of 99.94%, which meets the 99.9% verification threshold. The verification response time was 150ms. The central control unit then triggered the fixed shielding base station in the core area to activate full-band strong shielding, covering the frequency band from 100MHz to 6GHz, with a shielding power of 30dBm.

[0029] After the personnel completed the double-lock verification operation, they took out the classified hard drive. The intelligent security cabinet sensor captured the "carrier removal operation completed" signal and uploaded it to the central control unit. The system maintained a strong shielding state across the entire frequency band of the core area. After 5 minutes, it automatically switched to the normal shielding mode, shielding only the civilian communication frequency band, and the shielding power was reduced to 15dBm.

[0030] If a classified hard drive is not returned within 24 hours, the carrier anomaly monitoring algorithm will immediately trigger an alarm. The central control unit will lock all shielding devices within a 50-meter radius of the secure room to maintain a strong shielding state across the entire frequency band, and at the same time push the abnormal carrier log to the unit's security management department.

[0031] When an unqualified person approaches within 4 meters of the core area, the unqualified person identification trigger mechanism is activated, and emergency strong shielding is activated in a local area of ​​the core area. At the same time, the associated video surveillance system captures the person's real-time image and uploads it to the source tracing module after binding it with the abnormal alarm information, thus realizing closed-loop management of personnel verification, shielding protection, and abnormal evidence collection.

[0032] Implementation results: In this implementation, the false judgment rate of biometric verification was controlled within 0.01%, the blocking rate of classified signals throughout the entire process of carrier transfer reached 99.5%, and the tracing response time of abnormal carriers did not exceed 3 seconds. This completely solved the problem of the disconnect between personnel permissions and shielding strategies in traditional secure rooms, and realized classified protection throughout the entire process of carrier storage and retrieval.

[0033] Example 2 This embodiment provides a remote monitoring and scheduling control platform for signal shielding equipment, used for shielding and controlling mobile carriers involved in cross-regional confidential logistics transportation. Specific implementation details include: Purpose of implementation: To address the pain points in cross-regional classified logistics transportation, such as fixed shielding modes of mobile carriers, lack of segment-specific protection, and inability to maintain shielding after external power interruption, this invention enables segment-adaptive shielding strategy switching for transport carriers, while ensuring the battery life of shielding equipment in the absence of external power, thus preventing the leakage of classified signals during movement.

[0034] Initial setup: The mobile carrier scenario adaptation unit adapts to the multi-scenario shielding mode of the terminal. It pre-stores the type and boundary coordinates of the transportation segment, classifies highways and airports as public transportation segments, and classifies unit-specific channels as confidential handover segments. It sets the segment judgment distance threshold of the trajectory area linkage algorithm to 10 meters. It is equipped with a power supply component for the box-mounted shielding module, which includes a rechargeable lithium battery with a rated capacity of 10000mAh and a solar auxiliary power supply panel with a conversion efficiency of 20%.

[0035] The central control unit and the logistics GPS positioning system establish an encrypted communication link through the national cryptographic SM4 protocol, and the communication delay control threshold is set to 50ms; the low battery alarm threshold of the on-board shielding module is preset to 20%, and the emergency silent mode is triggered when the container door is unlocked without authorization or when a high-risk eavesdropping signal with an intensity of not less than -40dBm appears in the vicinity.

[0036] Control process: When the encrypted file box is transported to the highway section, the logistics GPS system feeds back the real-time coordinates of the carrier. After calculation by the trajectory area linkage algorithm, the straight-line distance between the carrier and the reference coordinates of the public road section boundary is 8 meters, which is less than the threshold of 10 meters. The central control unit determines that the carrier has entered the public transportation section and then triggers the on-board shielding module to start full-band strong shielding. The shielding frequency band covers 100MHz to 6GHz, and the shielding power is 25dBm.

[0037] When the carrier is transported to the unit's designated handover channel, the straight-line distance between it and the boundary of the classified handover section is 5 meters. The system automatically switches the shielding mode to directional weak shielding, shielding only the civilian communication frequency band from 800MHz to 2600MHz, while retaining the 350MHz police frequency band and the 400MHz emergency frequency band to ensure the emergency communication needs of the handover personnel.

[0038] If the container door is unlocked without authorization during transportation, the abnormal state triggers the logic to start. The onboard shielding module immediately enters emergency silent mode, maintaining strong shielding across the entire frequency band while activating local audible and visual alarms. The central control unit simultaneously receives real-time positioning information of the carrier, with a positioning error of 8 meters, and pushes it to logistics management personnel immediately.

[0039] When the remaining power of the on-board shielding module drops to 20%, the central control unit sends a low power alarm, and the solar auxiliary power supply panel is then activated, ensuring that the on-board shielding module can work continuously for more than 12 hours without external power supply.

[0040] Implementation results: During this cross-regional transportation, the switching response time of the road segment shielding mode was 0.8 seconds, the blocking rate of classified signals of the mobile carrier throughout the entire process was no less than 99%, and the battery life without external power supply met the needs of cross-provincial and municipal transportation, solving the core pain points of the rigid shielding mode and unreliable power supply of traditional mobile carriers.

[0041] Example 3 This embodiment provides a remote monitoring and scheduling control platform for signal shielding equipment, used for silent shielding control in precision testing in classified anechoic chambers. Specific implementation details include: Purpose of implementation: Addressing the pain points of traditional shielding equipment's electromagnetic radiation easily interfering with testing instruments and unstable shielding effects due to changes in the anechoic chamber environment when conducting precision testing in classified electromagnetic anechoic chambers, this solution achieves interference-free linkage between shielding protection and precision testing, while ensuring the long-term stability of the anechoic chamber's electromagnetic environment, guaranteeing the accuracy of test data and zero leakage of classified signals.

[0042] Initial setup: The fixed precision scene adaptation unit of the multi-scene shielding mode adaptation terminal is equipped with an electromagnetic environment baseline acquisition sensor, with the acquisition frequency set to once per second and the baseline data storage period to 1 year; the preset silent shielding mode parameters are: the electromagnetic radiation of the shielding device itself is controlled within 5dBμV / m and covers the frequency band from 10kHz to 1GHz, the power of directional low power interference is 10dBm, and the interference direction error does not exceed 5 degrees.

[0043] The automatic calibration cycle for the electromagnetic environment baseline is set to 7 days, and the threshold for judging electromagnetic radiation deviation is 3dBμV / m. The hazard monitoring parameters for the anechoic chamber are configured, with the alarm threshold for the width of the shielded door gap being 5 mm, the alarm threshold for the filter signal attenuation being 60dB, and the replacement response time limit for the backup shielded node being 2 seconds.

[0044] Control process: Before the anechoic chamber password algorithm verification test, the central control unit retrieves the historical electromagnetic baseline data of the area, while the sensors collect the current electromagnetic radiation data in real time. The calculated deviation between the two is 2dBμV / m, which is less than the calibration threshold of 3dBμV / m, so no baseline calibration is required.

[0045] After the test was started, the central control unit issued a command to switch the anechoic chamber shielding equipment to silent shielding mode. Monitoring showed that the electromagnetic radiation of the shielding equipment itself dropped to 4dBμV / m, and the directional error of the directional interference was 3 degrees. This not only blocked the confidential signals in the gaps of the anechoic chamber, but also did not interfere with the precision testing instruments in the room.

[0046] During the test, the sensor detected that the width of the gap in the shielding door was 6 mm, which reached the alarm threshold. The hazard monitoring mechanism of the darkroom was immediately activated, locking the start-up permission of the test equipment at the first time. At the same time, it dispatched backup shielding nodes within a 10-meter range to fill the gap. The replacement response time was 1.5 seconds, ensuring that there were no gaps in the shielding protection.

[0047] Seven days later, the system automatically started baseline calibration. The calculated deviation between the real-time electromagnetic radiation data and the historical baseline data was 3.2 dBμV / m, which exceeded the judgment threshold. The central control unit then automatically corrected the interference phase and frequency parameters of the shielding equipment. After calibration, the deviation value dropped to 1.8 dBμV / m, restoring the stability of the electromagnetic environment in the anechoic chamber.

[0048] Implementation results: During this test, the interference rate of the shielding equipment to the precision testing instruments was 0, the leakage blocking rate of confidential signals in the anechoic chamber reached 99.8%, and the stability of the electromagnetic environment after baseline calibration was improved to 99.5%, completely solving the problem of mutual interference between traditional anechoic chamber shielding and testing.

[0049] Example 4 This embodiment provides a remote monitoring and scheduling control platform for signal jamming devices, used for targeted jamming control of side-channel eavesdropping in classified office areas. Specific implementation details include: Purpose of implementation: Addressing the pain points of traditional classified office areas where full-area shielding disrupts normal office work and makes it impossible to accurately identify and locate eavesdropping signals, this solution achieves accurate identification, source location, and targeted interference of side-channel eavesdropping signals, eliminating the risk of espionage while ensuring normal communication in the office area.

[0050] Initial setup: The side-channel signal identification unit of the precision anti-eavesdropping shield terminal integrates a weak electromagnetic feature acquisition sensor with a sensitivity of -100dBm, capable of capturing weak electromagnetic signals in the 10kHz to 1GHz frequency band. It has a built-in side-channel signal classification algorithm based on a convolutional neural network with 2000 training samples. The algorithm loss function is iteratively optimized according to a preset formula, and the signal identification accuracy threshold is set at 98%, while the false alarm rate threshold is 0.5%.

[0051] The targeted shielding scheduling unit pre-stores the deployment locations of desktop-level micro directional shielding nodes, sets the error threshold for triangulation to 1 meter, controls the interference range of the micro shielding nodes within a micro-area of ​​2m×2m×2m, and the interference power does not exceed 8dBm; the anti-espionage handling ledger is encrypted and exported using the SM4 algorithm, and the ledger contains an audit verification code, which is composed of the generation timestamp, data hash value, and operator identification.

[0052] Control process: The sensor detected the current fluctuation signal of the keyboard keys around a classified computer and then transmitted it to the side channel signal identification unit. The classification algorithm identified and matched the signal. The matching results of 2,000 training samples showed that the signal identification accuracy rate was 98.5% and the false alarm rate was 0.3%, and the signal was determined to be a side channel espionage risk signal.

[0053] The targeted shielding scheduling unit initiates a triangulation positioning procedure to locate the source of the espionage signal. The final positioning error is 0.8 meters. Then, it sends a precise interference command to the miniature directional shielding nodes in the area. The interference frequency band is consistent with the espionage signal frequency band, and the interference power is 8dBm. The interference only affects a 2m×2m×2m area around the classified computer.

[0054] After the interference is handled, the system automatically generates an anti-espionage handling log. The log is encrypted with the SM4 algorithm and can be exported. The built-in audit verification code can quickly verify the log tampering, meeting the traceability requirements of the unit's confidentiality audit.

[0055] Implementation results: In this anti-espionage operation, the identification response time of the side-channel espionage signal was no more than 2 seconds, the positioning accuracy and interference range of the signal source met the preset requirements, the blocking rate of the espionage signal reached 99.94%, and the interference rate of normal office communication in the surrounding area was less than 1%, achieving a balance between accurate anti-espionage and normal office work.

[0056] Example 5 This embodiment provides a remote monitoring and scheduling control platform for signal shielding equipment, used for comprehensive coordinated shielding control in classified research parks. Specific implementation details include: Purpose of implementation: Addressing the pain points of fragmented shielding strategies across multiple scenarios, lack of a global risk assessment mechanism, and inability to trace end-to-end control data in classified research parks, this solution integrates the functions of multiple modules to achieve risk linkage control across the entire park, while simultaneously completing encrypted storage and rapid traceability of end-to-end data, thus constructing a comprehensive classified protection system for the park.

[0057] Initial setup: The central control unit has a built-in multi-dimensional classified risk decision engine, which integrates a weighted scoring algorithm and sets the weight coefficients for each risk dimension: personnel qualification risk weight is 0.3, carrier classified risk weight is 0.3, scene electromagnetic risk weight is 0.2, and espionage signal risk weight is 0.2. The value range of each risk coefficient is 0 to 10, and the strategy output response time of the decision engine is 100ms.

[0058] The data acquisition unit of the end-to-end monitoring and traceability terminal is set to a data acquisition granularity of seconds. The collected content covers personnel access records, shielding status changes, carrier transfer logs, electromagnetic environment data, and theft handling ledgers, etc. The data storage and traceability unit adopts a distributed encrypted storage architecture. Data is verified by SM3 hash algorithm and encrypted by SM4 algorithm before data storage. The traceability query interface supports multi-dimensional retrieval by time, personnel, carrier, and scenario, and the query response time is 3 seconds.

[0059] Control process: A highly qualified personnel carrying a Class 1 classified device entered the core area of ​​the park. A weak espionage signal with an intensity of 8 was detected in the area. The electromagnetic risk coefficient of the scene was 2. After calculation by a weighted scoring algorithm, the comprehensive risk value was 0.3×10+0.3×10+0.2×2+0.2×8=8. The central control center triggered the highest level of full-band strong shielding in the area, and the blocking rate of classified signals reached more than 99%.

[0060] An ordinary qualified person carries a level-two classified carrier into the park's buffer zone. There are no eavesdropping signals in this area, and the electromagnetic risk coefficient of the scenario is 3. The calculated comprehensive risk value is 0.3×5+0.3×5+0.2×3+0.2×0=3.6. The system triggers a medium-level directional shielding, which only shields civilian communication frequency bands.

[0061] The end-to-end monitoring and tracing terminal collects control data from various areas of the park in real time. Managers can retrieve the shielding status data of the core area for a certain period of time by time dimension. The query response time is 2 seconds. The system can automatically generate standardized confidentiality audit reports in Excel format to meet the audit requirements of the park's confidentiality management.

[0062] Implementation results: In this comprehensive park management and control operation, the matching accuracy between the shielding strategy and the risk level reached 99%. The end-to-end management and control data was stored using SM3 hash verification and SM4 encryption to ensure data integrity and tamper-proof security, meeting the confidentiality requirements for data storage in classified fields. The data collection integrity rate was no less than 99% (based on continuous 72-hour testing, with ≤3 missed collections). The response efficiency of multi-dimensional traceability queries met the preset requirements, solving the problem of fragmented shielding strategies in traditional parks across multiple scenarios and achieving coordinated protection against classified risks across the entire park.

[0063] Comparative Example 1 This comparison model provides a traditional single-area signal shielding platform, specifically including: Traditional configuration: Hardware configuration: Only fixed shielded base stations (covering a single area), basic card access control equipment, ordinary GPS locators (without linkage function), simple electromagnetic sensors (only monitoring signal strength) and local data storage hard drives are deployed; there are no miniature directional shielded nodes, no solar-assisted power supply components, and no biometric collection equipment. The shielded equipment only supports two fixed power modes: manual adjustment of the full frequency band or the civilian frequency band.

[0064] Software configuration: It adopts the basic TCP / IP communication protocol (without national cryptographic encryption), has no risk decision engine and core algorithm, and only has the function of remotely starting and stopping shielding devices; it has no personnel qualification and shielding permission mapping table, no carrier flow control logic, no side channel signal identification model, and the data is only stored locally in a scattered manner, with no encryption and traceability query interface.

[0065] Traditional implementation steps: Scenario for a classified secure room: Staff enter the secure room by swiping their cards and manually activate the full-band shielding mode (30dBm power) of the fixed shielded base station; when taking out classified materials, there is no automatic switching logic for the shielding strategy, and it is necessary to manually switch to civilian frequency band shielding after a 5-minute timer; there is no automatic alarm for materials not being returned within the time limit, and manual inventory and investigation are required periodically, with no linkage protection and evidence collection mechanism for abnormal personnel approaching.

[0066] Cross-regional logistics transportation scenarios: The container-mounted shielding module only supports fixed power full-frequency shielding throughout the entire process (no road segment adaptation) and has no emergency silent mode; the power supply relies solely on the built-in lithium battery (no solar assistance), and the shielding function is interrupted after the power is exhausted; there is no location alarm for unauthorized unlocking of the container door, only local audible and visual prompts, and managers cannot obtain the carrier's location in real time.

[0067] Testing scenario in a classified anechoic chamber: The shielding equipment has no silent shielding mode, and its own electromagnetic radiation interferes with precision testing instruments; there is no electromagnetic baseline calibration mechanism, and the gaps in the shielding door exceed the standard without a compensation strategy. It requires manual inspection to discover the problem and then manually dispatching backup equipment, with a response time of more than 30 minutes.

[0068] Anti-espionage scenario in office area: There is no side channel signal identification capability. After a suspected espionage risk is detected, a strong full-area shield is activated, and normal office communication is blocked at the same time. There are no targeted interference methods, so it is impossible to locate the source of espionage. Furthermore, there is no record of the handling process, so there is no condition for auditing and tracing.

[0069] In a scenario of comprehensive park-wide control: the shielding devices in each area operate independently, without a risk linkage mechanism, requiring manual issuance of shielding commands to each area; there is no end-to-end data collection, only device start-up and shutdown logs are retained, making multi-dimensional traceability and auditing impossible. A traditional signal jamming platform currently in use by a certain unit was selected as a comparative example. This platform only has the function of jamming the entire frequency band or civilian frequency band in a fixed area. It lacks personnel qualification linkage, risk decision-making, accurate anti-espionage and full-link traceability capabilities. The comparison of its core technical indicators with the platform of this invention is shown in the following table: See Table 1 for details.

[0070] Table 1. Comparison of parameters between traditional platforms and the present invention.

[0071] Compared with Examples 1-5 and Comparative Example 1, the traditional single-area signal shielding platform of the present invention (comparative example) only has the ability to shield the entire frequency band or civilian frequency band in a fixed area. It has core defects such as single protection dimension, lack of strategy adaptability, lack of linkage control and traceability function. Its side channel eavesdropping identification accuracy is less than 80%, the shielding strategy risk matching accuracy is less than 70%, and the average blocking rate of classified signals is only 90%. Moreover, it cannot realize the binding of personnel qualification verification and shielding strategy, and the differentiated protection of mobile carriers, making it difficult to meet the classified control needs of multiple scenarios.

[0072] In comparison, the platform of this invention demonstrates comprehensive technical advantages in five typical classified scenarios: In the scenario of accessing and storing classified materials in a classified secure room (Example 1), through cross-verification of dual biometric features and shielding linkage of material transfer, the pain point of disconnect between permissions and protection in traditional platforms is completely solved. The biometric false judgment rate is reduced to 0.01%, the signal blocking rate of classified materials transfer reaches 99.5%, the response time for tracing abnormal materials does not exceed 3 seconds, and a closed loop of "verification-shielding-evidence collection" for unqualified personnel is also realized; In the scenario of cross-regional classified logistics (Example 2), relying on the trajectory area linkage algorithm to achieve adaptive shielding switching of road segments, and with the help of solar-assisted power supply components, the response time for road segment shielding switching is only 0.8 seconds, the battery life is more than 12 hours without external power supply, and the signal blocking rate of classified materials throughout the mobile carrier is ≥99%, solving the problems of rigid shielding mode and unreliable power supply in traditional mobile carriers.

[0073] In the scenario of precision testing in a classified anechoic chamber (Example 3), the silent shielding mode controls its own electromagnetic radiation to 4dBμV / m, with an interference rate of 0 to the testing instruments. Furthermore, through a 7-day automatic baseline calibration mechanism, the stability of the electromagnetic environment in the anechoic chamber is improved to 99.5%, resolving the contradiction between traditional shielding and precision testing. In the scenario of anti-side channel espionage in a classified office area (Example 4), the recognition algorithm based on convolutional neural networks achieves a 98.5% espionage signal recognition rate. Combined with targeted shielding with 1-meter positioning, it not only achieves 99.94% blocking of espionage signals but also controls the surrounding communication interference rate to within 1%, overcoming the drawbacks of traditional full-area shielding. In the scenario of full-area control in a classified scientific research park (Example 5), the weighted risk decision engine achieves a 99% accuracy rate in matching shielding strategy risks. Coupled with an encrypted traceability system that collects data at the second level, it completes the organic integration of protection strategies for multiple scenarios and realizes auditable and traceable full-link control data.

[0074] Overall, the platform of this invention has achieved a leap from single fixed protection to full-domain intelligent linkage protection, an upgrade from no precise control to multi-dimensional targeted protection, and a breakthrough from no data traceability to encrypted and traceable closed loop. Its comprehensive confidentiality protection capabilities have achieved a qualitative leap compared with traditional platforms.
