It receives feedback data and feedback control commands, and sends the received feedback data back to the signal front-end module 201 in the form of baseband signal. The signal front-end module 201 performs data interaction with the cloud platform 300. The cloud platform 300 is used to interact with terminal devices via external communication networks or satellite links, receive feedback data uploaded by terminal devices, and send optimization strategy data to terminal devices.

[0035] Specifically, one embodiment of the present invention consists of a mobile user terminal 100, a terminal module, and a cloud platform 300 connected thereto via an external communication network and satellite. In this embodiment, the mobile user terminal 100 can be a smartphone or other handheld terminal, used to send user service data to the terminal device through a short-range wireless link and receive the returned service information. The mobile user terminal 100 includes multiple user terminals. For example, user terminal A sends a signal to user terminal B, and user terminal B transmits the returned signal to user terminal A through the terminal device. Therefore, the mobile user terminal 100 is used to receive / send data. This embodiment adopts an integrated layered architecture of "RF access - baseband processing - application computing - status monitoring and control - power management". The various modules of this terminal module are connected through the terminal bus inside the terminal device. The terminal bus is interconnected by a high-speed data bus and a low-speed control bus, forming a pluggable, expandable, manageable and controllable modular hardware platform. Among them, the signal front-end module 201, communication baseband module 202, application processing module 203, and status monitoring module realize emergency communication functions, while the battery management module, application processing module 203, and status monitoring and control module 204 realize emergency power management functions. In this embodiment, the cloud platform 300 connects bidirectionally with the terminal device via an external communication network or satellite, performs cloud-based learning and strategy optimization on the data uploaded by the terminal, and issues optimization strategy data, such as scheduling strategies and configuration instructions.

[0036] In a preferred embodiment of the present invention, the signal front-end module 201 is used for, but is not limited to: In the receiving link, heterogeneous radio frequency signals are received uniformly and processed first, including pre-selection filtering and low-noise amplification. Different communication links are selected and mutually isolated through radio frequency switch matrix to reduce co-channel / adjacent channel interference and intermodulation effects. Then, the preprocessed radio frequency signal is sent to the communication baseband module 202, preferably to the WIFI access unit in the communication baseband module 202; In the transmission link, the baseband signal carrying feedback data sent by the application processing module 203 and the status monitoring and control module 204 is subjected to second signal processing, including up-conversion, power amplification and output matching. Furthermore, in response to the baseband signal, a second signal processing is performed, and the processed baseband signal is sent to the cloud platform 300 through an external communication network, and the return signal is received and sent to the mobile user terminal 100. Furthermore, the power level transmitted to the cloud platform 300 is dynamically adjusted based on the received baseband signal to save power.

[0037] Preferably, the signal front-end module 201 is also used to set front-end signal protection, including ESD / surge protection, overpower / high VSWR protection and temperature rise protection, to reduce the risk of damage caused by strong electromagnetic environment, antenna mismatch or abnormal external feeder in emergency situations.

[0038] Specifically, the signal front-end module 201 has a built-in antenna and radio frequency front-end for unified transmission and reception and front-end processing of multiple heterogeneous signals. The heterogeneous signals include, but are not limited to, heterogeneous radio frequency signals such as satellite communication systems, 4G / 5G cellular networks, walkie-talkie private networks, radio stations, GNSS systems and WiFi local area networks. The module uses a single set of hardware (antenna, filter, amplifier, switch matrix) to provide unified access for all wireless standards such as satellite, cellular, and private networks, avoiding the redundancy of equipping each standard with an independent radio frequency channel.

[0039] In a preferred embodiment of the present invention, the communication baseband module 202 includes, but is not limited to, a 4G / 5G communication unit, a satellite communication unit, a walkie-talkie communication unit, a radio unit, a GNSS positioning unit, and a WiFi access unit, as well as a communication link formed by the above units. The above units can work together and, respectively, use public or private networks to complete the transmission and reception of voice, data, broadcast and positioning information, and exchange data with the application processing module 203 through the terminal bus. The communication baseband module 202 is used for, but is not limited to: After receiving the processed radio frequency signal through the WiFi access unit, it is adapted to different communication units. The processed radio frequency signal is demodulated to obtain service data. Multiple protocols of multiple communication links are matched through a multi-protocol stack to form link data. Specifically, the communication baseband module 202 supports multi-protocol stack adaptation, and respectively implements satellite link session management, cellular network access and authentication, intercom call control, WiFi hotspot / relay access, GNSS positioning calculation and time synchronization, etc. The system periodically sends service data and link data to the application processing module 203, receives feedback data from the application processing module 203, and receives feedback control commands from the status monitoring and control module 204. It then performs link switching according to the feedback control commands, preferably including but not limited to communication link selection, communication link fault switching, and communication link backup operations. Further, the link data includes but is not limited to link quality index data and link abnormal event data for each communication link. In another embodiment of the invention, the system is also used to send network status to the application processing module 203 and report abnormal events.

[0040] Specifically, the communication baseband module 202 is responsible for network status reporting, periodically outputting link quality indicators (such as RSSI / RSRP, SNR, RTT, packet loss rate, congestion level, link establishment delay, etc.), and supporting the reporting of abnormal events (disconnection, weak coverage, registration failure). Under the control of the multi-source link switching unit in the status monitoring module, it implements strategies such as multi-link backup, fault switching, load sharing, or traffic distribution according to service type, such as voice priority intercom / cellular, data priority cellular / satellite, and broadcast and alarm priority reliable links.

[0041] Preferably, the communication baseband module 202 can also exchange network status data with the user data access unit of the application status module.

[0042] As can be seen, through the above settings, the communication baseband module 202 not only completes multi-standard access, but also provides quantifiable feedback for upper-level decision-making.

[0043] In a preferred embodiment of the present invention, the application processing module 203 includes, but is not limited to: The user data access processing unit is used to uniformly parse the service data and link data transmitted by the communication baseband module 202, and fuse them with the working status data sent by the status monitoring and control module 204 to obtain a standardized state vector that can be uniformly adjusted. Preferably, after receiving the data, the user data access processing unit performs data preprocessing, including but not limited to noise suppression and filtering. Specifically, it parses, caches, denoises, and timestamps the voice / data / broadcast stream / network status parameters from the communication baseband module 202, and fuses the power supply, temperature, load, and other information from the status monitoring and control module 204 to form a unified state vector, so that adjustments can be made only through this standardized state vector.

[0044] The communication task scheduling and processing unit is used to make optimal or near-optimal decisions on factors including but not limited to link selection and switching, and power resource allocation control, and outputs decision control commands to drive the status monitoring and control module 204 and the power management module 205 to execute. Specifically, it integrates information such as multi-network link quality, service priority, latency / reliability constraints and power status to make optimal or near-optimal decisions on communication standard selection, link switching timing, resource allocation and power control, and outputs commands to drive execution. Furthermore, the communication task scheduling and processing unit also sends decision control commands to the communication baseband module 203, and the communication baseband module 203 receives the decision control commands and executes the corresponding task scheduling processing.

[0045] Preferably, the application processing module 203 further includes an end-to-cloud collaborative data interaction unit, used to upload feedback data to the cloud platform 300 or the communication baseband module 202. The feedback data includes, but is not limited to, terminal operating status data, link quality data, energy consumption data, and historical data. Correspondingly, the communication baseband module 202 is also used to receive the feedback data transmitted by the mid-end cloud collaborative data module of the application processing module 203 through a 4G / 5G communication unit, and modulate and encapsulate the feedback data to form a baseband signal. Further, the end-to-cloud collaborative data interaction unit is also used to establish a communication channel with the satellite, upload the feedback data to the cloud platform 300 through the communication channel, and receive optimization strategy data issued by the cloud platform 300.

[0046] Specifically, the edge-cloud collaborative data interaction unit is triggered only when the communication status is good. The edge-cloud collaborative data interaction unit interacts with the cloud through two paths. One is to send feedback data back to the communication baseband module 202. The communication baseband module 202 sends the data back to the signal front-end module 201 in the form of baseband signal, and then the signal front-end module 201 uploads it to the cloud platform 300 through the external communication network. The other is to establish a communication channel through satellite and use the connection between the satellite and the cloud platform 300 to transmit feedback data. That is, this unit can establish a secure communication channel with the cloud platform 300 to complete the uploading of terminal operating status, link quality, energy consumption characteristics and historical business data, as well as the distribution of cloud learning results, model parameters, policy templates and configuration files. It also performs legality verification, version management and rollback control on the distributed content to ensure that the policy is controllable and traceable.

[0047] As can be seen, the application processing module 203 is the core computing processing module of the terminal device, responsible for data processing, intelligent decision-making and global scheduling, ensuring that the terminal can achieve intelligent, efficient and collaborative operation under emergency conditions of limited resources and drastic environmental changes. The hardware of this module preferably includes a main control processor, system memory, encryption and secure boot module and local cache and log storage module, etc. Therefore, the application processing module 203 not only undertakes the traditional main control processing role, but also serves as the policy hub and the entry point for end-to-cloud collaboration.

[0048] In a preferred embodiment of this design, the status monitoring and control module 204 includes, but is not limited to: The terminal detection and control unit is used to collect real-time operating status data of the terminal device and input the operating status data into the user data access unit in the application processing module 203. The operating status data includes, but is not limited to, operating temperature, communication link quality, and power status. In a preferred embodiment, the terminal detection and control unit collects parameters such as terminal operating temperature, temperature rise of key components, communication link quality, battery power / voltage / current, charging and discharging status, and external load power in real time and provides them to the application and processing unit as decision input. When abnormalities such as over-temperature, over-current, disconnection, and repeated reconnection are detected, local protection and alarms are triggered, and the event log is reported. The multi-source link switching unit is used to send feedback control commands to the communication baseband module 202 according to the decision control commands output by the application processing module 203, drive the communication baseband module 202 to perform automatic link switching, and manage link backup. In a preferred embodiment, the multi-source link switching unit performs automatic switching and backup management of multiple communication loops such as satellite, 4G, walkie-talkie, broadcast and WiFi according to the decision control commands output by the application processing module 203. It preferably supports modes such as "primary and backup hot switching", "fault isolation" and "multi-link parallel traffic splitting", and maintains service continuity or minimal interruption during the switching process. The power detection and control unit is used to detect the status of each power supply output and external load, identify circuit abnormal risks, and issue power control commands to the power management module 205. In a preferred embodiment, the unit detects the status of each power supply output and external load, identifies risks such as short circuits, overloads, and abnormal plugging / unplugging, and issues control commands to the power management module 205 to achieve power supply path selection, current limiting protection, load disconnection, and graded power supply.

[0049] Through the above settings, the status monitoring and control module 204 realizes closed-loop control of perception, alarm, protection and execution, so that the terminal still has recoverable and protectable engineering reliability in harsh environments, and ultimately realizes real-time perception of terminal operating status, anomaly detection and hardware-level control of communication loop and power supply path.

[0050] In a preferred embodiment of the present invention, the power management module 205 is used to uniformly manage the internal power supply and external charging of the terminal device, receive decision control commands and power control commands issued by the application processing module 203 and the status monitoring and control module 204 respectively, and execute them according to the decision control commands and power control commands; the power management module 205 includes, but is not limited to: The battery module is used to provide DC power to the internal circuits of the terminal device and the external load; preferably, it provides a stable DC power to the internal circuits of the terminal device and the external load, preferably including a lithium battery cell pack and battery management, power estimation and balancing circuits, and has over-temperature, overcharge, over-discharge, overcurrent and short-circuit protection, so as to realize independent power supply capability and safety in emergency situations. The power supply management unit is used to manage the internal power supply and status monitoring of the terminal device, and to provide multiple outputs to the outside. Preferably, this unit performs voltage regulation, distribution and timing control on each power domain (such as high-power radio frequency domain, digital processing domain, low-power standby domain) of the terminal device, and provides multiple DC outputs to the outside (supporting USB-A / Type-C PD, DC round port, etc., optional); it has overcurrent / overvoltage / undervoltage / short circuit protection, soft start and surge suppression functions, and supports graded power-on, on-demand power-off and low-power standby for high-power communication modules. A photovoltaic charging unit is used to connect to a photovoltaic module to collect photovoltaic energy and to manage the charging of the battery module. Preferably, the unit is connected to a portable photovoltaic module with a solar panel, and preferably adopts an MPPT (maximum power point tracking) or equivalent energy harvesting control strategy to achieve efficient collection of photovoltaic energy and safe charging management of the battery module. The fast charging management unit is used to quickly charge the battery module and allocate power supply strategies when multiple charging power sources are connected. Preferably, the unit is used to achieve fast and safe charging of the battery module when multiple charging power sources (adapter, vehicle power supply, power bank, etc.) are connected. It preferably supports multiple fast charging protocols and input current limiting strategies, and automatically reduces the current rating when the temperature or battery status is abnormal.

[0051] In summary, one embodiment of the present invention can unify the access of multiple heterogeneous communication networks and, under the control of the communication task scheduling unit of the application processing module 203, realize automatic switching, backup and coordination between multiple links; at the same time, the power management module 205 performs unified management and efficient control of internal and external power, taking into account fast charging, photovoltaic energy replenishment and emergency power output, thereby constructing a portable integrated support terminal that integrates emergency communication and power supply, significantly improving the continuous communication and continuous power supply capabilities in scenarios such as sudden disasters, field operations and network and power outages.

[0052] like Figure 2 As shown, an embodiment of the present invention also discloses the software architecture corresponding to the system, which adopts a bottom-up layered design. The system includes a hardware abstraction and driver layer, an operating system and basic service layer, a communication and device middleware layer, a policy decision and resource scheduling layer, and an application service and human-computer interaction layer. A security and operation and maintenance support system is set up throughout each layer to achieve unified modeling, unified control and collaborative optimization of multi-mode communication capabilities and power supply assurance capabilities.

[0053] The specific functions of each layer are as follows: (1) The hardware abstraction and driver layer runs directly on the terminal processor and various functional devices. Through radio frequency and communication module drivers, power and battery management drivers, sensor and human-machine interface drivers, etc., it realizes the low-level control of peripherals such as 4G, satellite communication, walkie-talkies, WiFi, GNSS, power modules, photovoltaic charging modules, buttons, and displays. The hardware abstraction sublayer uniformly encapsulates different chips and interfaces, and provides standardized network interfaces, power interfaces, sensor interfaces and other access methods to the upper layer, thereby shielding hardware differences and providing a stable and consistent hardware operating environment for the upper layer software.

[0054] (2) The operating system and basic service layer runs on top of the hardware abstraction and driver layer, including the embedded operating system kernel, file system and storage management, time synchronization and timing services, and system log and fault recording modules. It is used to implement task scheduling, process management, memory and interrupt management, provide persistent storage and cache management of configuration parameters and business data, implement a unified time base based on GNSS or network, and record key events and abnormal information, thereby providing a reliable operating environment and basic system services for upper-layer business logic.

[0055] (3) The communication and equipment middleware layer abstracts various communication standards and power and status monitoring devices in a unified manner above the operating system. It sets up a multi-mode communication protocol stack and access middleware, power management middleware and status monitoring and alarm middleware. By adapting to protocols such as cellular network, satellite link, walkie-talkie private network, WiFi and encapsulating logical links, it realizes connection establishment, link quality assessment and heartbeat keep-alive. It also performs unified modeling of battery, power input and load output, and provides interfaces for power estimation, charging and discharging control and power consumption statistics. At the same time, it aggregates multi-source information such as temperature, power, battery health and communication status, realizes threshold alarm and event subscription, and provides standardized business data and equipment status for the strategy decision and resource scheduling layer.

[0056] (4) The strategy decision and resource scheduling layer is the core software layer of terminal intelligence. Based on the link quality data, power status information, service priority and user configuration parameters provided by the communication and equipment middleware layer, it constructs a multi-network collaborative strategy engine and a power and load scheduling engine. Through comprehensive judgment, it realizes the selection of primary and backup links, link aggregation or splitting, power mode switching and load priority management. It also exchanges strategy parameters and model weights with the cloud platform through the cloud platform collaboration and model update management module, supports the uploading of terminal operation data and the online updating of strategy models. At the same time, it combines the security policy and access control module to complete identity authentication, access control and configuration protection, thereby forming a closed-loop intelligent scheduling system of cloud platform learning and terminal execution.

[0057] (5) Application Service and Human-Machine Interaction Layer Based on the unified business interface provided by the strategy decision and resource scheduling layer, the application service and human-machine interaction layer constructs functional modules such as emergency communication service, power supply guarantee and power supply service, terminal configuration and status display interface, and local maintenance and self-test service. Through business logic such as voice call, short message, data packet, location reporting and multimedia upload, user business requests are submitted to the lower-level strategy engine for link selection and resource allocation. The power supply control results of external loads are presented, and a human-machine interface for network and power policy settings, system status monitoring and alarm display is provided. At the same time, one-click self-test, log export and software version query and upgrade are supported, which makes it convenient for on-site operators and remote maintenance personnel to configure and maintain the terminal.

[0058] (6) The security and operation and maintenance support system, as a vertical support module that runs through all layers, provides security and maintainability assurance for the entire terminal software stack. It includes functions such as software updates and remote upgrades, permission management and auditing, encryption and key management, and operation monitoring and health assessment. It achieves secure and reliable version upgrades and rollbacks through package downloads and breakpoint resumes. It records key configurations and operation and maintenance operations through hierarchical permissions and operation auditing. It protects communication and storage data from being leaked or tampered with through encryption algorithms and key management mechanisms. It continuously monitors the CPU, memory, storage and task operation status, and combines cloud platform analysis to achieve fault prediction and health assessment, thereby ensuring the long-term, secure and stable operation of the integrated multi-mode emergency communication and power supply smart terminal in complex environments.

[0059] The software architecture disclosed in this invention employs a bottom-up layered design, exhibiting high cohesion and low coupling. Each layer has clearly defined responsibilities and standardized interfaces, facilitating independent development and testing while significantly reducing system risks caused by cross-module changes. Furthermore, the combination of modularity and plug-in architecture allows for rapid iteration and smooth upgrades when adding new communication standards, service capabilities, or power management strategies by expanding corresponding modules. A multi-dimensional intelligent decision-making mechanism is introduced at the core processing and strategy decision-making layer, comprehensively considering link quality, power status, service priority, and cloud platform distribution strategies to adaptively optimize communication link selection and power scheduling. A unified security and operation and maintenance support system is constructed, achieving consistent cross-layer control over configuration management, operation logs, fault diagnosis, and online upgrades, improving stability and maintainability in complex emergency environments. In addition, relying on a unified resource view and scheduling mechanism, multi-network communication resources and multi-source power are managed and intelligently allocated in an integrated manner, effectively reducing system power consumption and operating costs while ensuring the continuity of critical services.

[0060] like Figure 3 As shown, one embodiment of the present invention also discloses the workflow of the system, which is mainly performed in the application processing module, and specifically includes: 1. System Startup and Initialization The integrated multi-mode emergency communication and power supply protection smart terminal disclosed in this invention enters the system startup and initialization phase after power-on or reset.

[0061] The initialization phase includes steps such as hardware self-test, driver loading, policy configuration synchronization, and basic service establishment.

[0062] Preferably, the hardware self-test is triggered by the underlying bootloader, which sequentially checks the integrity and working status of the communication module, power management module, non-volatile memory, various sensors, and peripheral interface circuits. When an anomaly is detected, the corresponding error code is recorded and a preset safe mode is entered to prevent high-risk tasks from being executed under abnormal hardware conditions. Otherwise, if all modules pass the test, the subsequent initialization process is allowed.

[0063] Subsequently, the underlying drivers and runtime libraries are loaded. The loading operations include, but are not limited to, the initialization of the communication protocol stack, the configuration of the power control driver, and the startup of the operating system kernel module and the task scheduler.

[0064] After loading is complete, the system establishes and confirms communication channels with each hardware module, and establishes a unified message queue and event publish / subscribe mechanism at the operating system layer to support reliable interaction and asynchronous event notification across modules.

[0065] The message bus can support functions such as priority scheduling, event rollback, and breakpoint resumption to improve the robustness of the system under complex operating conditions.

[0066] During software initialization, the terminal reads the policy configuration file from local non-volatile memory. The configuration file includes key operating parameters such as network priority configuration, power threshold parameters, battery health (SOH) and state of charge (SOC) related parameters, and service weight model.

[0067] The system compares the local configuration with the policy library of the cloud platform. When the cloud platform policy version is higher than the local version or there are policy changes, the end-to-cloud collaborative data interaction unit in the system obtains the updated content from the cloud platform through a secure upgrade process and replaces the local policy after the compatibility verification is passed, so that the terminal can maintain the consistency and controllability of the policy in different deployment scenarios.

[0068] Finally, the system starts basic services, including high-precision clock synchronization service, log management and persistent caching service, and security management service (such as key management and module integrity verification).

[0069] The clock synchronization service preferably obtains a unified time reference through GNSS or network time protocol for event timestamps and policy effectiveness determination; the log management and persistent caching service records the startup process, running events and abnormal information for subsequent remote diagnosis and cloud platform learning; the security management service starts the key loading, integrity check and security boot process.

[0070] At this point, the terminal has completed initialization and entered a working state, ready to receive upper-layer service scheduling and policy execution.

[0071] 2. Status Acquisition and Basic Environment Preprocessing During system operation, the input and sensing layer periodically collects multi-source operating parameters. Specifically, the terminal monitoring and control unit transmits data to the user data access unit, power management unit, and communication baseband module, respectively, and uses the terminal monitoring and control unit for monitoring and data collection. In a preferred embodiment of the present invention, the collected data includes, but is not limited to, bandwidth of cellular and satellite links, signal quality (SNR / RSRP), round-trip time (RTT), jitter, packet loss rate, congestion / load level, handover cost, and energy consumption per unit of data; battery charge (SOC), state of health (SOH), voltage, current, temperature, external power supply status, and system load power consumption on the power supply side; and operating status on the device side, such as CPU / memory usage and temperature.

[0072] To avoid anomalous data contaminating decision-making, all the multi-source data mentioned above are accessed in a structured manner through a unified sampling framework, ensuring that data from different sources have a consistent format and timestamp alignment capability, and performing basic preprocessing before entering the decision-making process: 1) Noise suppression and filtering For noisy measurements, digital filtering is first used for initial smoothing.

[0073] The program is pre-configured to use a first-order exponential smoothing model to filter out acquisition jitter: in, The coefficients are updated by the cloud platform. To smooth out the result of the previous shot, This is the current sample value. This is the smoothed result of the current shot.

[0074] For data with strong time correlation, such as link RSSI, SNR, and battery voltage curves, this embodiment of the invention further uses Kalman filtering for optimal estimation to reduce the influence of system noise and measurement noise; the state prediction equation of the Kalman filter is: in, Let A be the predicted state at time k based on all information up to time k-1, and let A be the state transition matrix. Let B be the optimal estimate at time k-1, and let B be the control input matrix. It is a known external control variable; The measurement update equation is: in, This represents the state vector at time K, such as link quality state, battery SoC / SoH state, etc. The actual measurement value comes from the sensor at time k. Let H be the Kalman gain and H be the observation matrix.

[0075] The Kalman gain is calculated as follows: in, R is the measurement noise covariance matrix, which is the predicted state covariance matrix. This structure ensures that the terminal can still obtain a stable and reliable state estimate in a strong noise environment.

[0076] 2) Anomaly detection and data reconstruction To address anomalies such as instantaneous spikes, jump interference, and link jitter that occur in complex environments for multi-source state parameters, one embodiment of this invention proposes a closed-loop method for outlier detection and repair of time-series data. This method is based on a sliding window, which calculates robust statistics in real time within the window and simultaneously performs joint discrimination from two dimensions: "amplitude deviation" and "change rate mutation". This ensures sensitivity while suppressing false alarms and avoids reverse contamination of the statistical baseline by outlier samples.

[0077] First, the system segments the input sequence using a sliding window.

[0078] Construct a sliding window of length N for time t: in, Let N be the sliding window dataset at time t, where t is the current time and N is the length of the sliding window. Calculate the first quartile within each window and the third and fourth quartiles And defined by the interquartile range: in, The interquartile range of the data within the time window at time t; further, robust center and scale quantities are constructed to replace traditional methods such as mean / standard deviation to enhance the ability to resist outliers: in, The robust center of the data within the time window at time t, To prevent zero constant, Let be the robust scaling measure of the data within the window at time t.

[0079] Compared to the mean and standard deviation, this statistic is insensitive to extreme values ​​and can significantly improve the robustness of anomaly detection.

[0080] To avoid contaminating statistics with outliers, the system can employ a "freeze or remove" strategy, meaning the statistics are determined only by the valid sample set. estimate.

[0081] Secondly, a "dual-channel anomaly detection" model is established: one channel is for amplitude anomalies, which uses normalized residuals to determine whether a sample is far from the normal distribution center. in, The amplitude-normalized residual of the sampled value at time t, Let be the original sampled value at time t, when satisfying ,in, The first is the threshold for judging amplitude anomalies, which indicates that a point has a significant outlier deviation; the second is the jump anomaly channel, which uses first-order difference to describe the degree of instantaneous change: The quartile statistics method is also used to construct the scale (difference sliding window) for the difference sequences. ): in, For robust scaling measures of difference sequences, The first difference at time t; thus forming the jump derivative. : When satisfied This indicates that there is currently a sudden disturbance or a discontinuous transition.

[0082] The system supports fusing candidate decisions using voting / logic methods, for example: To avoid occasional false alarms caused by noise from a single sampling, the system introduces a continuous verification mechanism: it counts the number of candidate anomalies within the most recent M sampling points. Only when satisfied The anomaly is only confirmed and the repair and alarm logic is triggered at that time.

[0083] This strategy can effectively distinguish between "single-point spikes" and "persistent anomalies / step drifts," improving the stability and reliability of detection decisions.

[0084] Furthermore, the system selects different processing strategies according to the anomaly pattern during anomaly repair: for single-point spikes or outliers, a quartile-based clamping (Winsorize / clip) method is used to limit outliers to a reasonable range. in It can be used to distinguish between mild and extreme abnormalities.

[0085] For abrupt or transient disturbances, a smooth replacement method is used to fuse the current value with the output of the previous time step according to the coefficient, in order to suppress the cascading impact of sudden changes on subsequent state estimation and resource scheduling. in This is the suppression intensity parameter.

[0086] For persistently confirmed anomalies (such as sensor offset or distribution migration caused by sudden changes in link status), in addition to outputting anomaly flags, the system can also enter a "freeze update" mode to prevent the anomalous segments from participating in statistical updates, and to ensure continuous and stable updates. Restore adaptive updates after clicking: This enables a closed-loop control system of "anomaly isolation - stable recovery" based on robust statistics and anti-pollution updates.

[0087] Through the above mechanism, the system can realize real-time detection, robust confirmation, online repair and statistical self-adaptation of abrupt outliers, which not only ensures the timeliness of the anomaly response, but also avoids misjudgment and statistical pollution, providing stable and reliable data input for subsequent weighted fusion, state estimation and task scheduling.

[0088] 3) Weighted fusion of multi-source data Furthermore, to improve the accuracy of comprehensive state determination, this embodiment of the invention proposes a multi-source data adaptive weighted fusion model, which performs weighted fusion on data from different sensors or different network modules to obtain a unified fusion estimate.

[0089] No. The sensor data source output is The corresponding weight is The fusion model is then: The weights can be adaptively calculated based on the credibility / uncertainty of each data source.

[0090] Typically, when the data source noise follows a zero mean and a variance of , When dealing with random perturbations, the "inverse variance normalization" method can be used to allocate weights, giving higher weights to high-confidence (small variance) data sources. in Indicates the first The confidence noise variance of each data source is obtained from historical statistics, online estimation, or quality index mapping.

[0091] To further enhance the robustness of the project, when a data source exhibits anomalies, exceeds limits, or experiences a decline in health, its participation in the fusion process can be suppressed through gating, such as by setting a validity coefficient. (or ): in This indicates that the source has been removed or downweighted at the current moment to avoid outliers causing bias in the fusion result.

[0092] Through the aforementioned weighted fusion mechanism, this embodiment of the invention integrates cellular link status, satellite link status, historical prediction results, and real-time measurement data to achieve a stable assessment of overall link quality / service availability, providing a robust and adaptive decision-making basis for network switching and resource scheduling.

[0093] 4) State object generation and structured encapsulation The preprocessed parameters are organized into a unified structured object according to categories, including communication state objects. Power status object Business Request Object wait.

[0094] The unified object structure is represented as: Each parameter It includes descriptive fields such as timestamp, confidence level, and source, which facilitates cross-module calls and fusion inference in the core processing layer.

[0095] 5) Real-time distribution and millisecond-level response Finally, all structured objects (including link status, device health, power supply, service load and location, etc.) are encapsulated into a unified message by the input and perception layer after generation, and pushed to the core processing layer in real time through the internal system message bus in a "publish / subscribe (Pub-Sub)" manner to achieve a low-latency closed loop.

[0096] The core processing layer can trigger rapid policy evaluation and scheduling instructions for critical events (such as rapid degradation of link quality, increased power risk due to decline in battery SOC and temperature rise, sudden changes in business priority, etc.), forming a millisecond-level response link.

[0097] To ensure real-time performance and determinism, the message bus supports topic-based classification, priority-based preemption, and timestamp-based ordered delivery. It also employs a circular buffer and zero-copy / few-copy transmission mechanisms to reduce queuing and handling overhead. Furthermore, it introduces control strategies such as timeout discarding, backpressure, and rate shaping to prevent message congestion caused by sudden surges in traffic.

[0098] Through the above mechanisms, the system can realize real-time updates and rapid convergence of communication link selection, power mode switching and service scheduling strategies in dynamic environments, ensuring end-to-end service continuity and emergency support capabilities.

[0099] 3. Business Access and Request Generation The terminal receives user interaction input or instructions from the upper-level system at the application layer and generates service trigger events; the services include, but are not limited to, emergency voice calls, data transmission, video surveillance, location reporting, group intercom and alarm broadcasting.

[0100] The processor performs unified parsing and standardized encapsulation of business requirements from different sources and in different formats, transforming them into computable and schedulable business request objects. This supports joint decision-making for subsequent communication link selection, power mode switching, and resource scheduling.

[0101] The business request object It must contain at least the following fields: 1) Business Identifier and Type: Business Type Business ID, session / task lifecycle information; 2) Priority and Preemption Attributes: Priority Whether preemption / being preempted is allowed, and the concurrency limit; 3) QoS constraint set: minimum bandwidth constraint Maximum end-to-end delay constraint Maximum packet loss rate constraint ; 4) Timeliness and reliability requirements: Deadline or timeliness level, reliability level (e.g., whether redundant transmission / link hot standby is required). 5) Security and compliance requirements: Encryption / authentication level (e.g., encryption algorithm level, key length, whether national cryptographic suite is required), data integrity verification requirements; 6) Degradable strategies and scope: Set of business degradation measures Including frame rate Range, resolution Collection, bitrate Upper and lower limits, reporting cycle Adjustable range, sampling rate / compression ratio, and other parameter boundaries.

[0102] The above constraints are expressed in structured vector form: When the request is generated, a timestamp, source identifier, and validity period are added to each field to ensure the traceability and executability of business requests in a dynamic environment.

[0103] Through the above standardization process, the terminal transforms business requirements from "descriptive instructions" into "constrainable, evaluable, and degradable" business request objects, providing consistent input for the subsequent link scoring, policy generation, and scheduling execution of the joint decision-making module.

[0104] In one implementation, such as Figures 4-5 As shown, the terminal APP provides a unified business entry interface, which is used to quickly map user operations into standardized business request objects.

[0105] When a user clicks on the corresponding entry point or receives a task assignment instruction, the APP triggers a business request generation process, automatically fills in the key constraints and context information required by the business, and distributes them uniformly with other structured objects.

[0106] For example, when a user triggers SOS via the interface or a physical button, the terminal app generates an emergency service request object. The priority and preemption attributes are set to the highest, preemption is allowed, and the concurrency limit is set to 1. The corresponding bandwidth, latency, packet loss rate, timeliness, reliability, and security level are given. At the same time, a degradeable policy is preset. When the network or power is insufficient, voice and location are prioritized, video quality is automatically turned off or reduced, and the reporting cycle is relaxed. After attaching a timestamp, source, and validity period to the object, it is submitted to the joint decision module, which completes the link selection, power mode adjustment, and resource scheduling. Other low-priority services are rate-limited or degraded. When the environment changes, the service is dynamically degraded according to the preset policy and the status is reported back, forming a closed loop from SOS service triggering to execution and adjustment.

[0107] In summary, the embodiments of the present invention have the following technical effects: First, by adopting cross-domain collaboration and closed-loop control, it breaks through the limitations of simple splicing of traditional equipment. By unifying the modeling of communication status, power status and service requirements, a closed-loop control mechanism for joint perception, decision-making and scheduling is constructed.

[0108] This enables link selection, service carrying, and power supply strategies to work together in emergency scenarios with limited resources and changing environments. It fundamentally solves the problems of strategy conflicts and resource competition that exist in the traditional simple combination of "communication equipment + mobile power supply", and achieves priority protection and continuous operation of critical services. Second, an adaptive intelligent decision-making system is constructed to improve the continuity and efficiency of emergency response, and to enable intelligent conversion from multi-source data to a unified decision-making state. Through the combination of local rule reasoning and cloud-based strategy push, the system can autonomously generate the optimal strategy under extreme conditions such as weak network and power shortage, and reduce communication interruption time from minutes to seconds or even milliseconds, which greatly improves the reliability of emergency communication and the efficiency of emergency response.

[0109] Third, establish a cloud-edge collaborative learning and evolution mechanism to achieve a shift from passive response to proactive prevention. The terminal can achieve rapid local response and continuously optimize strategies with the help of big data analysis and machine learning capabilities in the cloud. This enables the terminal to detect risks in advance and proactively adjust strategies, shifting from passive response to proactive prevention. At the same time, remote software upgrades reduce the operation and maintenance costs throughout the entire life cycle, enabling the continuous evolution of system functions.

[0110] Fourth, it provides integrated power supply protection to suppress the risk of secondary failure of critical links; the integrated intelligent power management system supports multi-source input and unified scheduling, and has a hierarchical energy saving and priority power supply mechanism. When the power is insufficient or the input is abnormal, it can automatically ensure the power supply of core communication units, extend the battery life of critical services, and fundamentally avoid secondary failure of communication systems caused by power outages.

[0111] Fifth, it adopts a modular and customizable design to improve adaptability and scalability; the modular architecture of the terminal supports flexible configuration of communication standards, battery capacity and interface type according to the needs of different emergency scenarios, which can meet the needs of backpack deployment in high-intensity rescue and also adapt to handheld applications by individual soldiers.

[0112] This customizable design significantly improves the device's environmental adaptability and task suitability.

Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments.
