Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent security technology, in particular to a multi-device cooperative space intelligent defense system and a control method thereof. BACKGROUND

[0002] Space intelligent defense is a concept of protecting and defending space-based infrastructure and ground systems using advanced technical means. It combines artificial intelligence, big data, the Internet of Things, network space security and other technologies to achieve security protection for space activities. This defense system can monitor and warn potential threats in the environment in real time, and comprehensively analyze potential threats to take appropriate defense measures. Existing security systems rely on passive alarm and manual response methods, lack active identification, real-time blocking and dynamic intervention capabilities. With the development of unmanned devices, edge computing and AI identification technology, the demand for active space defense is increasingly urgent. However, existing systems often face problems such as dispatch delay, device isolation, missing evidence chain, and unclear high-risk behavior processing procedures. Currently, the urban space security and prevention system has obvious structural deficiencies, mainly in the following aspects: 1. Current status of spray marking identification technology: Existing target marking technology is mostly used in industrial or police dyeing warning systems, but lacks logical connection between subsequent identification devices, target confirmation mechanisms and evidence collection systems. Patent (CN215622726U) discloses a device for unmanned aerial vehicles to carry spray dyeing agents, aiming to improve the spray range, but does not cover coding identification or related technical measures for subsequent identification behavior, and cannot form a closed-loop system of "marking - identification - tracing"; 2. Unmanned device individual tracking technology: Patent (CN105447459A) relates to a method for automatically identifying and tracking unmanned aerial vehicle targets using image recognition to track individual targets, but does not rely on markers and does not involve device cooperation or tracking task relay. Patent (CN106485736A) proposes a multi-view unmanned aerial vehicle tracking system based on image fusion, but this technical solution is limited to image stitching and long-distance positioning, and has no direct effect on whether the target is marked or constitutes judicial evidence; 3. Multi-device cooperative control and police cooperation: Patent (CN110180112B) relates to the cooperation of unmanned aerial vehicles and ground robots to perform patrol and emergency response, but this patent belongs to an emergency robot system and does not consider key security elements such as target confirmation, identity marking, subsequent attack behavior and evidence storage modules; 4. Lack of legal tracing capability: Most urban security systems have real-time monitoring, but it is difficult to form a data evidence chain bound to the marking, identification and tracking chain, making it difficult to effectively provide evidence after the fact. SUMMARY

[0003] The application provides a multi-device cooperative space intelligent defense system and a control method thereof, which can effectively solve the problems in the background art.

[0004] To achieve the above-mentioned purpose, the application provides the following technical scheme: a multi-device cooperative space intelligent defense system, which has a spray marking identification, unmanned device cooperative tracking and non-lethal attack capability, integrates image recognition, behavior judgment, non-lethal intervention, evidence collection and storage functions, realizes marking, identification, cooperative tracking and non-lethal control of illegal intrusion targets, and specifically includes a private domain spray device, a city linkage response device, a central control platform and an evidence storage module.

[0005] According to the above technical scheme, after detecting illegal intrusion behavior of a target, the private domain spray device releases a substance containing a unique identification code to the target and automatically uploads alarm information of the event geographic coordinates and the target number.

[0006] According to the above technical scheme, the unmanned device includes an unmanned aerial vehicle and an unmanned ground vehicle, the unmanned aerial vehicle is arranged on the top platform of a city lighthouse or a special tower arranged at a preset interval, the unmanned ground vehicle is enclosed in a police device cabin and a police platform, and the intercepting device includes an electromagnetic locking door, a lifting column and a telescopic roadblock, and has a remote triggering containment structure. The unmanned device has an identification module, which includes an image collector, a thermal imaging device, a spectrum sensor and a sensor assembly with identification capability, which can be used alone or in combination, and the identification module can improve the target identification accuracy by using a multi-state fusion method based on the fluorescence characteristics and spectrum response value or other morphological characteristics of the carried marker substance. The unmanned devices also have real-time communication capability between devices, and any two or more unmanned devices can also have a data transmission capability communication mechanism without the central control platform, which supports real-time target data sharing and path adjustment state synchronization to exchange relevant data of target identification information, position state data and execution capability state data in real time, and the unmanned devices can determine the consistency of the target based on the exchanged data, determine whether it is the same target individual carrying the identification code, and the target consistency determination is mainly based on the matching of the identification code of the marker, and the multi-modal feature similarity comparison result of the image.

[0007] According to the technical scheme, the unmanned devices can execute a relay tracking mode and a surrounding capture and attack mode. In the relay tracking mode, the device most suitable for continuous tracking takes over the task, and the remaining devices enter standby or observation state. In the surrounding capture and attack mode, multiple unmanned devices simultaneously lock a target position and coordinate action paths to jointly surround and synchronously deploy non-lethal restrictions on the target.

[0008] According to the technical scheme, the central control platform collects data information uploaded by each module, and determines a target risk level, a path prediction, a task priority, and a response strategy based on the data information. The target risk level includes low risk, medium risk, and high risk. The central control platform can dynamically adjust task assignment and device response time interval according to the risk level. The platform can also coordinate task switching, information synchronization, and surrounding capture deployment plan among unmanned devices, and generate records and dispatch logs for key actions. In the path prediction, the central control platform calculates the next movement position of the target based on the current coordinates, movement direction, and historical path information of the target, for the coordinated adjustment of the response strategy of the unmanned devices. The central control platform timestamps all device task instructions, response states, and attack authorization records, and automatically generates task execution log archives.

[0009] According to the technical scheme, after receiving target positioning information uploaded by the spraying device and any unmanned device, the central control platform automatically identifies all unmanned devices with response capabilities within a preset geographical radius centered on the target real-time coordinates, case identification information, and regional device state, and distributes task information to the devices in the region to enter a standby linkage state.

[0010] According to the technical scheme, the unmanned device further includes a non-lethal restriction module. After receiving an authorization instruction from the central control platform, the non-lethal restriction module can execute physical and biological restriction measures such as directional light irradiation and high-frequency sound emission. It can only execute physical or biological blocking and action behavior restriction on the target after receiving an authorization operation confirmation from the artificial. The execution timing of the non-lethal restriction module supports unified scheduling by the platform and self-coordinated execution among devices. The non-lethal restriction module can be equipped as needed to adapt to the restriction requirements of different distances and target sizes.

[0011] According to the technical scheme, the evidence storage module is deployed in each unmanned device in addition to the central control platform. Each unmanned device automatically generates an evidence data package with a unique case identification when starting a task, assigns a globally unique case storage data serial number, and synchronously transmits it to the central control platform in real time. Each unmanned device writes real-time data into a local evidence caching area during the execution of tracking and identification tasks, and synchronously uploads evidence data streams to the central control platform in real time through a communication mechanism. After the central control platform first receives the evidence data packet uploaded by any device, a case evidence entry corresponding to the serial number is established in the database for subsequent unified archiving and judicial extraction; In the case of automatic joining of other unmanned devices in a cooperative task or a relay task, the original execution device transmits the case identification and data packet key information to the new device through the device-to-device communication mechanism. The new device inherits the original data serial number and continues to generate corresponding structured data packets, which are synchronously uploaded to the platform, ensuring that the case evidence chain data is uninterrupted, uninterrupted and undivided; The evidence storage module adds a target unique identification code and a device number to each piece of data when generating an electronic evidence package, which is used for responsibility tracing. The evidence storage module also has an abnormal chain breakage repair mechanism that can restore and generate a gap explanation after data loss, ensuring evidence continuity. The electronic evidence package is uploaded to the tamper-proof electronic evidence platform after being encrypted by digest, for the law enforcement department to retrieve the evidence.

[0012] According to the above technical solution, a multi-device cooperative space intelligent defense control method includes the following steps: S1, target illegal intrusion detection and initial marking; S2, multi-unmanned device cooperative identification of target; S3, multi-unmanned device cooperative tracking of target; S4, central control platform scheduling and decision-making; S5, non-lethal attack and interception under manual authorization; S6, full-process evidence storage and judicial traceability.

[0013] According to the above technical solution, when the private domain spraying device deployed in the key area detects a target illegal intrusion behavior, the illegal intrusion behavior includes crossing the boundary and entering the restricted area, and immediately releases the marking substance and uploads the alarm information; The release of the marking substance is to release a substance containing a unique identification code to the target. The substance can be identified through physical and non-physical methods such as image, infrared, ultraviolet, spectrum or micro-radiation, and the attachment stability is greater than 72 hours; The uploaded alarm information is to synchronously upload the basic information of the event geographic coordinates, target number and marking substance code to the central control platform to trigger the system response process; The S2 is to identify the marked target by the unmanned device in the city linkage response device using the built-in identification module. The unmanned device includes unmanned aerial vehicles on fixed lighthouses, unmanned ground vehicles in police equipment cabins, etc. In the specific identification process, through single device or multi-device joint identification, the unmanned device uses sensor components alone or in combination, based on the fluorescence characteristics of the marker substance and the polymorphic characteristics of the spectral response value, combined with image matching algorithms, to confirm the target carrying the unique coded marker substance; After multiple unmanned devices detect the target at the same time, the target identification information is exchanged through inter-device communication, and based on the similarity comparison of multi-modal features, it is determined whether it is the same target individual, the consistency of the target is determined, and repeated tracking is avoided; S3, after confirming the target, the unmanned device enters tracking mode to achieve efficient cooperative tracking. Specifically, the unmanned devices exchange target position state and execution capability state data through real-time communication mechanism, and dynamically adjust the tracking strategy; When the current tracking device cannot continue tracking due to exceeding the detection range or insufficient power, the system automatically identifies other responsive unmanned devices in the region, synchronizes the case identifier and tracking data summary to the new device, the new device inherits the original data sequence number, continues tracking and supplements real-time data, and ensures uninterrupted tracking; When multiple devices cooperatively track, the device dynamically plans its own path through inter-device communication to avoid path intersection or interference, and when new devices join or exit the task, the original device automatically synchronizes data to the new device to ensure tracking continuity; S4, the central control platform is used as the core hub to participate in task management and dynamic scheduling throughout the process, including data collection and situation analysis, regional device linkage activation, and task priority and response strategy; Among them, data collection and situation analysis refers to real-time receiving of target coordinates, tracking trajectory, and device state data uploaded by private domain injection devices and unmanned devices, combining target historical path, moving direction, risk level, and predicting the next moving position of the target through the path prediction module; Regional device linkage activation is to define a linkage coverage area with a preset geographical radius centered on the real-time coordinates of the target, identify all unmanned devices with response capabilities in the region, and add them to the standby linkage device set to prepare for capture, containment or strike tasks; Task priority and response strategy dynamically adjust task assignment and device response time interval according to target level. If the target level does not reach the threshold, tracking and monitoring are prioritized, and if the target level reaches the threshold, manual authorization is required before execution; S5, through the central control platform, the target information is pushed to the manual terminal, and after the authorized personnel explicitly confirm, the strike instruction is generated. After the unmanned device or interception device receives the strike instruction, the following measures are executed through the non-lethal restriction module: Directional strong light irradiation, high-frequency sound wave emission and other physical and biological restriction methods that restrict the target's activities without causing permanent damage to restrict the target's activities; In addition, the central control platform synchronously triggers the blocking equipment of the area entrance and exit, the blocking equipment including an electromagnetic locking door, a lifting column and a retractable roadblock, forming a physical lock on the target advancing path, and cooperating with the unmanned equipment to complete the surrounding capture. S6, generating and storing a complete evidence chain in the defense process, ensuring traceability, specifically, each unmanned equipment participating in the task automatically generates a local evidence package with a unique case identification at the beginning of tracking, and synchronizes to the central control platform in real time, the central control platform establishes a case storage entry after receiving, and is associated to a globally unique serial number; When the equipment exits due to failure or task handover, the new added equipment inherits the original case identification and continues to supplement evidence data, if data loss occurs, the evidence storage module generates a gap explanation by meansing abnormal chain supplementing mechanism, and traces back the historical data to ensure the integrity of the evidence chain; The local evidence package is uploaded to the tamper-proof electronic evidence platform after being abstracted and encrypted, and the judicial department can call the complete evidence chain through the case identification or serial number for responsibility identification and legal traceability.

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example 1: like Figures 1-5 As shown, the present invention provides a technical solution, a multi-device collaborative space intelligent defense system, which has the capabilities of spray marking and recognition, unmanned equipment collaborative tracking and non-lethal strike, and integrates image recognition, behavior judgment, non-lethal intervention, evidence collection and storage functions to mark, identify, collaboratively track and non-lethally control illegal intrusion targets. Specifically, it includes private domain spraying equipment, urban linkage response equipment, central control platform and evidence storage module. The private spraying equipment automatically releases substances containing unique identification codes. The city-linked response equipment consists of multiple unmanned devices deployed in the urban spatial grid structure and interception devices at the entrances and exits of the area. The central control platform is used to collect data information uploaded by each module. The evidence storage module is used to collect spraying numbers, identification images, tracking trajectories and control information to form an electronic evidence package containing the above elements.

[0019] Based on the above technical solution, after detecting illegal intrusion behavior by a target, the private domain spraying device releases a substance containing a unique identifier code to the target and automatically uploads alarm information such as the geographical coordinates of the event and the number of targets. The substance contains a marker component that can be identified by physical or non-physical means such as images, infrared, ultraviolet, spectroscopy, and micro-radioactivity. The adhesion stability is no less than 72 hours. The identification code is unique and used for subsequent identification and traceability.

[0020] Based on the above technical solutions, the unmanned equipment includes unmanned aerial vehicles and unmanned ground vehicles. The unmanned aerial vehicles are located on the top platforms of urban lighthouses and special towers deployed at preset intervals. The unmanned ground vehicles are enclosed in police equipment cabins and police platforms. The interception equipment includes electromagnetic lock doors, rising bollards and telescopic roadblocks, and remotely triggered control structures. All unmanned devices have an identification module, which includes an image acquisition device, a thermal imaging device, a spectral sensor, and sensor components with identification capabilities. These components can be used individually or in combination. The identification module can improve the target identification accuracy by using a multi-mode fusion method based on the fluorescence characteristics and spectral response values ​​or other morphological characteristics of the marker material it carries. The unmanned devices also have real-time communication capability between devices. Any two or more unmanned devices can have a communication mechanism with data transmission capability without the central control platform. The communication mechanism supports real-time target data sharing and path adjustment state synchronization to exchange relevant data of target identification information, position state data, and execution capability state data. The unmanned devices can determine target consistency based on the exchanged data, determine whether it is the same target individual carrying the same flag code, and determine target consistency based on flag code matching, image multi-modal feature similarity comparison results.

[0021] Based on the above technical solutions, the unmanned devices can perform relay tracking mode and encirclement and strike mode. In the relay tracking mode, the unmanned device most suitable for continuous tracking takes over the task, and the remaining devices enter standby or observation state. In the encirclement and strike mode, multiple unmanned devices simultaneously lock the target position and coordinate the action path to achieve joint encirclement and synchronous non-lethal restriction deployment of the target. During the encirclement and coordination process of the unmanned devices, the devices dynamically plan their own travel paths through communication with each other to avoid path intersection and interference, thereby improving the encirclement efficiency. When other unmanned devices join the coordination and relay task, the original execution device automatically sends the case identification and data summary information to the new device. The new device continues to build the same case data structure and synchronously uploads real-time evidence data to the central control platform, ensuring the continuity of the data chain. When any unmanned device is about to lose relevant execution capability, the system automatically triggers the node redistribution mechanism to transfer the current task to other devices in a relayable state, ensuring uninterrupted tracking.

[0022] Based on the above technical solutions, the central control platform collects data information uploaded by each module and determines the target risk level, path prediction, task priority, and response strategy based on the data information. When the central control platform determines that the target risk level is low based on the data information, it means that the target level does not reach the threshold and has no violent tendency. The central control platform prioritizes tracking and monitoring of the target and, when the unmanned device is out of range, performs relay tracking through another unmanned device. The central control platform can dynamically adjust task assignment and device response time intervals based on risk levels. The platform can also coordinate task switching, information synchronization, and encirclement deployment planning between unmanned devices, and generate records and scheduling logs for critical actions. When the central control platform predicts the path, it calculates the next movement position of the target based on the target's current coordinates, movement direction, and historical path information, which is used for coordinated response strategy adjustment by the unmanned devices. The central control platform timestamps all device task instructions, response states, and strike authorization records, and automatically generates task execution log archives.

[0023] Based on the above technical scheme, after the central control platform receives the target positioning information uploaded by the spraying device and any unmanned device, it will automatically identify all unmanned devices with response capability within a preset geographical radius range centered on the target real-time coordinate, case identification information and regional device state, and distribute task information to the devices in the region to make them enter the standby linkage state; And after the central control platform receives the target coordinate, target state, identification level and device distribution state in the region uploaded by any unmanned device in real time, it will automatically complete the regional situation analysis by combining the case evidence identification, target level and the position information of the callable unmanned devices in the current region. The central control platform sets a certain geographical radius coverage interval centered on the current coordinate of the target, identifies all unmanned device nodes with response capability in the region, and distributes real-time tracking data, early warning state and task type instructions to these nodes to make them enter the standby response state without interrupting the original task, ready to execute cooperative capture, containment response or non-lethal strike; The scheduling behavior is dynamic, and the platform will update the linkage coverage and distribute task devices in real time based on the target movement state to ensure scheduling accuracy and system response efficiency, avoid resource waste and intervention overlap.

[0024] Based on the above technical scheme, the unmanned device further comprises a non-lethal restriction module. After receiving the authorization instruction of the central control platform, the non-lethal restriction module can execute physical and biological restriction measures such as directional light irradiation and high-frequency sound emission. It can execute physical or biological interruption and action behavior restriction on the target only after manual authorization operation confirmation. The execution timing of the non-lethal restriction module supports unified scheduling of the platform and self-cooperative execution between devices, and the non-lethal restriction module can be equipped as needed to adapt to the strike needs under different distances and target size conditions.

[0025] Based on the above technical scheme, the evidence storage module is deployed in the central control platform and each unmanned device. Each unmanned device generates an evidence data package with a unique case identification when starting a task, assigns a globally unique case storage data serial number, and synchronously transmits it to the central control platform in real time; Each unmanned device writes real-time data into the local storage cache area during the execution of the tracking and identification task, and synchronously uploads the evidence data stream to the central control platform in real time through the communication mechanism. After the central control platform receives the evidence data package uploaded by any device for the first time, it establishes a case storage entry corresponding to the serial number in the database for subsequent unified archiving and judicial extraction; And in the case of other unmanned devices automatically joining the cooperative task or relay task, the original executing device transmits the case identification and data packet key information to the new device through the inter-device communication mechanism, the new device inherits the original data sequence number and continues to generate the corresponding structured data packet, and synchronously uploads it to the platform, ensuring that the case evidence chain data is uninterrupted, uninterrupted and undivided; The evidence storage module attaches a target unique identification code and a device number to each piece of data when generating an electronic evidence package, which is used for responsibility tracing. The evidence storage module also has an abnormal chain breakage repair mechanism that can restore and generate a gap explanation after data loss, ensuring evidence continuity. The electronic evidence package is uploaded to the tamper-proof electronic evidence platform after being encrypted and summarized, and is available for the judicial department to retrieve the evidence.

A multi-device collaborative space intelligent defense system according to claim 5, characterized in that: After receiving the target positioning information uploaded by the spraying equipment or any unmanned equipment, the central control platform will automatically identify all responsive unmanned equipment within a preset geographical radius centered on the target based on the target's real-time coordinates, case identification information, and regional equipment status, and distribute the task information to the equipment within the area, putting them into a standby linkage state.

7. A multi-device collaborative space intelligent defense system according to claim 5, characterized in that: The unmanned equipment also includes a non-lethal restraint module, which is activated after receiving an authorization command from the central control platform; The execution timing of the non-lethal restriction module supports unified platform scheduling and self-coordinated execution between devices. Furthermore, the non-lethal restriction module can be configured as needed to adapt to the strike requirements under different distances and target sizes.

8. A multi-device collaborative space intelligent defense system according to claim 5, characterized in that: In addition to being deployed on the central control platform, the evidence storage module is also deployed in each unmanned device. When each unmanned device starts its task, it automatically generates an evidence data package with a unique case identifier, assigns a globally unique case storage data sequence number, and transmits it to the central control platform in real time. During the tracking and identification process, each unmanned device writes real-time data to the local evidence storage cache and simultaneously uploads evidence data streams to the central control platform in real time through a communication mechanism. Once the central control platform receives the evidence data packet uploaded by any device for the first time, it establishes a case evidence storage entry corresponding to the sequence number in the database for subsequent unified archiving and judicial retrieval. In cases where other unmanned devices automatically join collaborative or relay tasks, the original executing device transmits the case identifier and key information of the data packet to the newly joined device through the device communication mechanism. The new device inherits the original data sequence number and continues to generate the corresponding structured data packet, which is then uploaded to the platform synchronously to ensure that the case evidence chain data is uninterrupted, unbroken, and not fragmented. When generating electronic evidence packages, the evidence storage module adds a unique target identifier and device number to each piece of data for accountability. The evidence storage module also has an abnormal chain break repair mechanism, which can trace back and restore data after data loss and generate gap descriptions to ensure the continuity of evidence. The electronic evidence package is uploaded to the tamper-proof electronic evidence platform after being encrypted with a digest, so that judicial departments can retrieve and preserve it.

9. A multi-device collaborative space intelligent defense control method, characterized in that: Includes the following steps: S1, Target unauthorized intrusion detection and initial labeling; S2, multiple unmanned devices collaboratively identify targets; S3, multiple unmanned devices collaboratively track targets; S4, Central Control Platform for Scheduling and Decision-Making; S5, non-lethal strikes and interceptions under human authorization; S6, full-process evidence preservation and judicial tracing.

10. A multi-device collaborative space intelligent defense control method according to claim 9, characterized in that: S1 refers to the immediate release of marker material and uploading of alarm information when the private domain spraying equipment deployed in key areas detects illegal intrusion behavior of the target, including crossing the boundary or entering the restricted area. The release of a marker substance involves releasing a substance containing a unique identifier code into a target. This substance can be identified by physical and non-physical means such as images, infrared, ultraviolet, spectroscopy, or micro-radioactivity, and its adhesion stability is greater than 72 hours. Uploading alarm information involves synchronously uploading basic information such as the geographical coordinates of the event, the number of people in the target area, and the code of the marked substance to the central control platform, triggering the system response process. The S2 refers to the identification of marked targets by unmanned equipment in the city linkage response device using a built-in identification module. The unmanned equipment includes unmanned aerial vehicles on fixed lighthouses, unmanned ground vehicles in police equipment cabins, and other unmanned equipment. In the specific identification process, identification is carried out by a single device or multiple devices in combination. Unmanned devices use sensor components alone or in combination. Based on the fluorescence characteristics and polymorphic features of the spectral response values ​​of the marker substance, combined with image matching algorithms, the target is confirmed to carry a uniquely coded marker substance. After multiple unmanned devices detect a target simultaneously, they exchange target identification information through inter-device communication. Based on multimodal feature similarity comparison, they determine whether the target is the same individual, thus achieving target consistency determination and avoiding repeated tracking. S3 refers to the unmanned equipment entering the tracking mode after the target is confirmed, so as to achieve efficient collaborative tracking. Specifically, the unmanned equipment exchanges data on the target's location status and execution capability status through a real-time communication mechanism, and dynamically adjusts the tracking strategy. When the current tracking device is unable to continue tracking due to exceeding the detection range or insufficient power, the system automatically identifies other responsive unmanned devices in the area, synchronizes the case identifier and tracking data summary to the new device, and the new device inherits the original data serial number, continues tracking and supplements real-time data to ensure uninterrupted tracking; When multiple devices are tracking together, the device dynamically plans its own path through communication between devices to avoid path crossing or interference. When a new device joins or leaves the task, the original device automatically synchronizes data to the new device to ensure tracking continuity. The S4 refers to using the central control platform as the core hub to participate in the entire process of task management and dynamic scheduling, specifically including data collection and situation analysis, regional equipment linkage activation, and task priority and response strategies. Among them, data collection and situation analysis refers to receiving data such as target coordinates, tracking trajectory and equipment status uploaded by private domain spraying equipment and unmanned equipment in real time, and combining the target's historical path, direction of movement and risk level to predict the target's next movement position through the path prediction module. Regional equipment linkage activation is to define a linkage coverage area with a preset geographical radius centered on the real-time coordinates of the target, identify all unmanned equipment with responsive capabilities within the area, add them to the standby linkage equipment set, and prepare to carry out encirclement, control or strike missions. The task priority and response strategy dynamically adjusts the task assignment and equipment response time interval based on the target level. If the target level does not reach the threshold, tracking and monitoring are performed first. If the target level reaches the threshold, manual authorization is required before the attack can be carried out. S5 involves pushing target information to a human terminal via a central control platform. After explicit confirmation by authorized personnel, an attack command is generated. Upon receiving the attack command, the unmanned equipment or interception equipment executes the following measures through a non-lethal restraint module: Physical and biological methods of restricting target movement without causing permanent damage, such as directional intense light irradiation and high-frequency sound wave emission; In addition, the central control platform simultaneously triggers the interception equipment at the area's entrances and exits. The interception equipment includes electromagnetic locks, rising bollards, and telescopic barriers, which form a physical blockade on the target's path of advance, and work with unmanned equipment to complete the encirclement and capture. The S6 is to generate and store a complete chain of evidence during the defense process to ensure that responsibility is traceable. Specifically, each unmanned device participating in the mission automatically generates a local evidence package with a unique case identifier when the tracking begins, and synchronizes it to the central control platform in real time. After receiving it, the central control platform establishes a case evidence entry and associates it with a globally unique serial number. When a device is removed due to malfunction or task handover, a newly added device inherits the original case identifier and continues to supplement evidence data. If data loss occurs, the evidence storage module uses the abnormal chain breakage repair mechanism to trace back historical data and generate gap descriptions to ensure the integrity of the evidence chain. Local evidence packages are uploaded to the tamper-proof electronic evidence platform after being encrypted with a summary. Judicial departments can retrieve the complete chain of evidence through case identifiers or serial numbers for liability determination and legal tracing.
