Description

Technical Field

[0001] This invention relates to the field of satellite communication simulation technology, and in particular to a ground satellite station simulation method and system for satellite communication simulation. Background Technology

[0002] With the widespread application of satellite communication technology in various fields, the number of personnel engaged in satellite communication equipment operation, network maintenance, and abnormal condition handling continues to expand, and the corresponding demand for skills training is also constantly increasing. Due to the high cost of purchasing real equipment, limited training scenarios, and the potential for unnecessary interference with real satellites in orbit, most organizations use simulation training systems for daily training.

[0003] Currently, most commonly used satellite communication simulation training systems are developed in a single form. Some purely digital simulation systems can only replicate the device operation interface, and the signal transmission and link establishment logic are all idealized, resulting in significant deviations from actual communication scenarios. Some hardware-in-the-loop simulation systems can only support small-scale networking of similar devices, failing to meet the needs of large-scale training organizations with more trainees. Furthermore, some independent radio frequency simulation devices can only complete signal simulation of a single link and cannot interconnect with digital simulation or hardware-in-the-loop simulation devices. Different types of simulators form independent training islands, allowing trainees to only complete basic single-machine operation training and preventing comprehensive training involving multi-site collaboration and cross-type device networking. The coverage of training content is significantly limited.

[0004] The functions of existing satellite communication simulation training systems are mostly developed in a fragmented manner. Task planning, training organization, abnormal condition injection, and performance evaluation are deployed in different independent systems. Each training session requires manual synchronization of training plans and configuration of equipment parameters across multiple systems. This not only consumes a lot of time in pre-training preparation but also easily leads to inconsistencies in parameter configuration, affecting the normal conduct of training.

[0005] Meanwhile, existing systems can only handle a limited number of abnormal operating conditions, including basic faults such as simple link interruptions and equipment shutdowns. They cannot simulate complex meteorological environments, various types of natural noise and electromagnetic interference, nor can they reproduce various equipment soft faults and parameter configuration errors that may occur in actual operating scenarios. The realism of the training scenarios is insufficient, and trainees cannot receive training in handling abnormal operating conditions that closely resemble real-world scenarios. Furthermore, most simulation training systems can only operate independently, lacking standardized external interfaces. They cannot be connected to standardized collaborative training environments, nor can they exchange data with external systems such as training guidance and evaluation, electromagnetic spectrum management, and information system operation and maintenance, making it difficult to support cross-system collaborative training tasks.

[0006] Existing simulation training systems also suffer from deficiencies in network management configuration and performance evaluation capabilities. Satellite communication network parameters in most systems require manual calculation and input, especially configuration items such as uplink / downlink frequency conversion and channel resource allocation. Errors are easily made during manual calculation, leading to network malfunctions. Performance evaluation relies heavily on instructors manually recording trainees' operations and assigning scores based on evaluation criteria. This is not only inefficient but also susceptible to the influence of instructors' subjective judgments, resulting in inconsistent evaluation results. Furthermore, most systems fail to fully record equipment status, trainee operations, and link changes throughout the entire training process. The post-training debriefing lacks comprehensive data support, making it difficult to accurately pinpoint problems in trainees' operations or iteratively optimize the training content, thus hindering the continuous improvement of training quality. Summary of the Invention

[0007] This invention provides a ground satellite station simulation method and system for satellite communication simulation, to solve the problems existing in related technologies. The technical solution is as follows: In a first aspect, embodiments of the present invention provide a ground satellite station simulation method for satellite communication simulation, comprising: Construct a multi-form simulation environment, including a radio frequency simulator, a hardware-in-the-loop simulator, and a digital operating simulator. The radio frequency simulator simulates the signal generation, up-conversion, and transparent forwarding of the radio frequency link. The hardware-in-the-loop simulator simulates the physical operating interface and equipment operation process of the ground station equipment through physical hardware. The digital operating simulator simulates the equipment operating interface and interface operation process in a digital simulation manner. Establish a unified control and data management platform. The platform is connected to each simulator to manage the running status and resource configuration of each simulator in a unified manner, including operation timing synchronization and dynamic allocation of simulation resources. Based on the management results, it generates satellite communication service schemes and network planning configuration parameters. Based on network planning and configuration parameters, the platform controls each simulator to access the communication link. The radio frequency simulator is connected to the radio frequency signal link via up and down converters and splitters and combiners. The hardware-in-the-loop simulator and the digital operating simulator are connected to the network communication link via service channel equipment and control channel equipment. The radio frequency signal link and the network communication link achieve signal-level interconnection via splitters and combiners. The platform performs unified network control on each simulator based on signal-level interconnection. Under unified network control, the platform schedules each simulator to collaboratively execute satellite communication simulation operation tasks based on the satellite communication service scheme, and injects preset channel interference scenarios and equipment failure modes; Collect task execution data, evaluate the communication performance of each simulator and generate evaluation results, and feed them back to the platform to adjust the satellite communication service plan and network planning configuration parameters.

[0008] Furthermore, the method also includes: establishing interfaces between the platform and external systems, including an information and communication training and evaluation system, an information system operation and maintenance simulation system, a channel and environment simulation system, and an electromagnetic spectrum management simulation training system; the platform receives training schemes, scheduling instructions, and voice data from the information and communication training and evaluation system, the information system operation and maintenance simulation system, and the channel and environment simulation system, respectively. The training scheme is used to generate satellite communication service schemes and report equipment status to the information and communication training and evaluation system and spectrum status to the electromagnetic spectrum management simulation training system.

[0009] Furthermore, the platform generates satellite communication service plans and network planning configuration parameters based on the management results. This includes: configuring link support relationships, communication link organization, mission time periods, network types, network architecture, resource usage, and technical configuration elements through the plan formulation module to generate satellite communication service plans; executing site planning, link planning, and channel planning through the network planning module to generate network planning configuration parameters; and executing satellite communication network operation parameter configuration, subnet configuration, service parameter setting, operation status configuration, communication environment parameter setting, and fault mode configuration through the network configuration module, and distributing the network planning configuration parameters to the radio frequency simulator, the hardware-in-the-loop simulator, and the digital operation simulator.

[0010] Furthermore, the platform schedules each simulator to collaboratively execute satellite communication simulation operation tasks based on the satellite communication service scheme, and injects preset channel interference scenarios and equipment failure modes, including: creating simulation tasks and loading preset scenario configurations, which include preset channel interference scenarios and equipment failure modes, and completing simulation preparation through resource configuration and operator seat configuration of RF simulators, hardware-in-the-loop simulators and digital operation simulators; during the simulation, the platform displays the working status and communication link status of each simulator in real time, and dynamically injects preset channel interference scenarios and equipment failure modes according to the satellite communication service scheme.

[0011] Furthermore, the platform, based on the satellite communication service scheme, schedules various simulators to collaboratively execute satellite communication simulation operation tasks, including: configuring abnormal operating condition categories and handling procedures. Abnormal operating condition categories include equipment damage, link interruption, electromagnetic interference, site failure, parameter error, and manual intervention. Among them, electromagnetic interference and link interruption correspond to channel interference scenarios, and equipment damage and site failure correspond to equipment failure modes. The abnormal operating condition categories and handling procedures are configured according to the technical configuration elements and network type in the satellite communication service scheme; simulating electromagnetic environment noise and interference through the platform's electromagnetic environment simulation module, including cosmic noise, antenna noise, atmospheric noise, rainfall noise, and ground noise; performing business anomaly handling, operational condition handling, and emergency situation handling through the platform's network handling module; and collecting electromagnetic spectrum information of the FDMA integrated service network and UHF mobile communication network through the platform's electromagnetic spectrum reporting module and pushing it to external systems.

[0012] Secondly, embodiments of the present invention provide a ground satellite station simulation system for satellite communication simulation, comprising: The multi-form simulation module includes a radio frequency simulator, a hardware-in-the-loop simulator, and a digital operating simulator. The radio frequency simulator is used to simulate the signal generation, up-conversion, and transparent forwarding of the radio frequency link. The hardware-in-the-loop simulator is used to simulate the physical operating interface and equipment operation process of the ground station equipment through physical hardware. The digital operating simulator is used to simulate the equipment operating interface and interface operation process through digital simulation. The unified control and data management platform includes a mission planning subsystem, a network scheduling subsystem, an abnormal operating condition handling subsystem, and a performance evaluation subsystem. The mission planning subsystem is used to generate satellite communication service schemes and network planning configuration parameters. The network scheduling subsystem is used to organize simulation equipment to establish satellite communication links and execute simulation tasks. The abnormal operating condition handling subsystem is used to inject channel interference scenarios and equipment failure modes during the simulation process. The performance evaluation subsystem is used to collect mission execution data and generate evaluation results. Among them, the radio frequency simulator is connected to the radio frequency signal link via up and down converters and splitters / combiners. The semi-physical operation simulator and the digital operation simulator are connected to the network communication link via service channel equipment and control channel equipment. The radio frequency signal link and the network communication link achieve signal-level interconnection via splitters / combiners. The unified control and data management platform performs virtual and physical unified network control on each simulator based on signal-level interconnection.

[0013] Furthermore, the network scheduling subsystem includes a digital station configuration module. The digital station configuration module generates the corresponding digital station configuration based on the site planning in the network planning configuration parameters and the network type in the satellite communication service scheme, and sends the digital station configuration to the digital operation simulator to drive the digital operation simulator to perform equipment startup and operation simulation.

[0014] Thirdly, embodiments of the present invention provide an electronic device, including a memory and a processor. The memory and the processor communicate with each other via an internal connection path. The memory stores instructions, and the processor executes the instructions stored in the memory. When the processor executes the instructions stored in the memory, it causes the processor to perform the method described in any of the above embodiments.

[0015] Fourthly, embodiments of the present invention provide a computer-readable storage medium that stores a computer program, wherein when the computer program is run on a computer, the methods in any of the embodiments described above are executed.

[0016] Compared with existing technologies, the beneficial effects of this invention are: This invention constructs a multi-mode simulation environment comprising a radio frequency (RF) simulator, a hardware-in-the-loop (HIL) simulator, and a digital operating simulator. The three types of simulators are connected to the RF signal link via up / down converters and splitters / combiners, and to the network communication link via service channel equipment and control channel equipment, respectively. The RF signal link and the network communication link achieve signal-level interconnection at the splitter / combiner. Thus, the real RF signal generated by the RF simulator and the service signals from the digital and HIL simulators can interact at the same network level. A unified control and data management platform can then treat the three types of simulators as different nodes in the same network for unified network control. This allows trainees to complete the entire training process from stand-alone operation and network setup to end-to-end service transmission within the same training environment. The HIL simulator provides a realistic operating feel, while the concurrent capabilities of the digital operating simulator support large-scale collaborative training, improving both the breadth of training coverage and the realism of the scenario.

[0017] Because the platform uniformly manages the operating status and resource configuration of each simulator and generates satellite communication service schemes and network planning configuration parameters, and controls each simulator to access the communication link based on these configuration parameters, the platform uniformly completes the operation timing synchronization and simulation resource dynamic allocation. All types of simulators work together under unified scheduling, avoiding resource contention and configuration inconsistencies among multiple forms and tasks.

[0018] Because the platform, under unified network control, schedules each simulator to collaboratively execute satellite communication simulation operation tasks based on the satellite communication service scheme, and injects preset channel interference scenarios and equipment failure modes, training can reproduce abnormal situations of links and equipment as needed within the same network control framework, enabling trainees to be trained in an environment close to actual use scenarios, thus enhancing the realism of the training. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the architecture of the ground satellite station simulation system for satellite communication simulation proposed in this invention; Figure 2 This is a structural block diagram of an electronic device according to an embodiment of the present invention. Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the ground satellite station simulation system 100 for satellite communication simulation disclosed in this invention includes two main parts: a unified control and data management platform 1 and a multi-mode simulation module 2. The two are connected through a standard bus (such as Ethernet, PCIe, etc.) or network communication to form a virtual and real ground satellite station simulation environment.

[0022] Specifically, the multi-mode simulation module 2 includes three types of simulators, which respectively reproduce the ground satellite station from three dimensions: "real signal", "physical operation" and "digital concurrency".

[0023] The RF simulator 21 is used to simulate signal generation, up-conversion, and transparent forwarding of RF links. Built with real RF devices or RF simulation boards, it can generate intermediate frequency (IF) or RF signals conforming to satellite communication standard waveforms (such as DVB-S2, CCSDS, etc.), complete up- and down-conversion, and output the received signal after frequency conversion in a transparent forwarding manner, changing only the carrier frequency and path, without altering the signal content. Because the RF simulator 21 outputs real, measurable RF signals, it gives the entire system "signal-level" realism, rather than just upper-layer logic simulation.

[0024] The hardware-in-the-loop simulator 22 is used to simulate the physical operation interface and equipment operation process of ground station equipment through physical hardware. It uses real equipment panels, knobs, buttons, indicator lights and other physical parts (or high-fidelity replicas), and works with an embedded controller to reproduce the physical operation process of powering on the equipment, setting parameters, and switching states, so that operators can have the same operating feel as the real equipment.

[0025] The digital operation simulator 23 is used to simulate the device operation interface and interface operation process through digital simulation. It runs software on the general computing platform 1, replicates the device operation panel and menu logic with a graphical interface, supports parameter configuration and process operation by mouse or touch, and is quick to deploy and easy to run concurrently on a large number of terminals, thereby meeting the needs of large-scale concurrent training.

[0026] The unified control and data management platform 1 is the "central hub" of the system, including the task planning subsystem 11, the network scheduling subsystem 12, the abnormal working condition handling subsystem 13, and the performance evaluation subsystem 14.

[0027] The mission planning subsystem 11 is used to generate satellite communication service schemes and network planning configuration parameters. Internally, it is implemented through the collaborative efforts of three modules: a scheme formulation module, a network planning module, and a network configuration module. The scheme formulation module configures link support relationships, communication link organization, mission time periods, network types, network architecture, resource usage, and technical configuration elements to generate a satellite communication service scheme. The network planning module performs site planning, link planning, and channel planning, generating network planning configuration parameters. The network configuration module performs satellite communication network operation parameter configuration, subnet configuration, service parameter settings, operational status configuration, communication environment parameter settings, and fault mode configuration, and distributes the network planning configuration parameters to the radio frequency simulator 21, the hardware-in-the-loop simulator 22, and the digital simulator 23. Since the scheme, planning, and configuration are all automatically generated and distributed with a single click by platform 1, manual calculation and input of error-prone items such as uplink / downlink frequency conversion and channel resource allocation are avoided, reducing configuration inconsistencies from the outset.

[0028] The network scheduling subsystem 12 is used to organize the simulation equipment to establish satellite communication links and execute simulation tasks. The network scheduling subsystem 12 includes a digital station configuration module. This module generates corresponding digital station configurations based on the station planning parameters in the network planning configuration parameters and the network type in the satellite communication service scheme, and then distributes these configurations to the digital operation simulator 23 to drive the simulator to start up the equipment and perform operation simulations. Therefore, operators do not need to manually build each station interface; they can conduct operation simulations on the correct station configuration, improving preparation efficiency and consistency.

[0029] The abnormal operating condition handling subsystem 13 is used to inject channel interference scenarios and equipment failure modes during the simulation process. The abnormal operating condition handling subsystem 13 includes an intervention control module, an electromagnetic environment simulation module, a network handling module, and an electromagnetic spectrum reporting module. The intervention control module generates and issues corresponding intervention commands for equipment damage, link interruption, electromagnetic interference, site failure, and parameter errors. For example, for link interruption, it generates a "switch to backup link" command and issues it to the network scheduling subsystem 12; for parameter errors, it generates a "parameter reset" command and issues it to the corresponding simulator. The electromagnetic environment simulation module simulates electromagnetic environment noise and interference, including cosmic noise, antenna noise, atmospheric noise, rainfall noise, and ground noise, which can be injected individually or in combination. The network handling module performs service anomaly handling, operational condition handling, and emergency situation handling. The electromagnetic spectrum reporting module collects electromagnetic spectrum information from the FDMA integrated service network and the UHF mobile communication network and pushes it to external systems. Because abnormal operating conditions are generated and intervention commands are issued by a unified subsystem according to category, the handling actions are standardized and traceable. The performance evaluation subsystem 14 is used to collect task execution data and generate evaluation results, providing a basis for subsequent closed-loop optimization.

[0030] The RF simulator 21 is connected to the RF signal link via up / down converters 41 and splitter / combiner 42; the semi-physical operation simulator 22 and the digital operation simulator 23 are connected to the network communication link via service channel equipment 43 and control channel equipment 44. The service channel equipment 43 modulates or converts the service data generated by the digital operation simulator 23 or the semi-physical operation simulator 22 to form the signal carrying user services in the network communication link (baseband data can be modulated to intermediate frequency or adapted to network transmission format), and the control channel equipment 44 carries signaling and configuration commands. The RF signal link and the network communication link achieve signal-level interconnection via splitter / combiner 42, that is, the real RF signal generated by the RF simulator 21 and the service signal modulated and converted by the service channel equipment 43 in the network communication link are interconnected at the signal level. The two-way signal interaction process is as follows: In the downlink direction, the real radio frequency signal output by the RF simulator 21 through the up / down converter 41 enters the service channel equipment 43 through the up / down converter 42. The service channel equipment 43 down-converts and demodulates the signal, converts it to baseband or network format, and then processes it for the digital operation simulator 23 or the hardware-in-the-loop (HIL) simulator 22, so that the digital and HIL simulators can directly use the real signal from the RF link. In the uplink direction, the service data generated by the digital operation simulator 23 or the HIL simulator 22 is modulated by the service channel equipment 43 and up-converted by the up / down converter 41. Then, it is combined with the output of the RF simulator 21 through the up / down converter 42 in the RF link, thereby realizing the injection of signal into the RF link. The unified control and data management platform 1 performs unified virtual and real network control of each simulator based on this signal-level interoperability: Platform 1 uses the demultiplexer 42 to align and synthesize the real radio frequency carrier of the radio frequency simulator 21 with the radio frequency service signal formed by modulation by the service channel equipment 43 and upconversion by the upconverter 41 in terms of frequency and time, and uniformly allocates frequency points (as well as the time slots or frame structures required for hybrid multiple access), so that the three types of simulators can work collaboratively as different site nodes in the same network. This "signal-level" rather than just "logic-level" interoperability truly integrates virtual and real devices into the same network.

[0031] This embodiment uses a comprehensive scenario as an example: A unit needs to conduct an "emergency communication support" simulation training. The goal is to establish a star network consisting of one central station and two remote stations, operating in the Ku band and using QPSK modulation. The process requires reproducing link fading caused by rainfall and practicing handling power amplifier failures at remote stations. The RF simulator 21 provides a real Ku-band carrier and performs up-conversion and up-conversion forwarding; the hardware-in-the-loop simulator 22 consists of two physical operator seats for physical operation; the digital simulator 23 runs concurrently on five terminals using a software interface; the platform 1 generates a service plan and configuration for "star network, Ku, QPSK" through the task planning subsystem 11 and distributes it to each simulator; each simulator connects to two links via up-converters 41, splitters / combiners 42, service channel equipment 43, and control channel equipment 44, achieving signal-level interconnection at the splitter / combiner 42, and is uniformly controlled by the platform 1. This constitutes a simulation system that includes real signals, accommodates large-scale concurrency, and can be uniformly scheduled.

[0032] Based on the above system, the method of the present invention is operated according to the following steps.

[0033] A multi-mode simulation environment is constructed, and an RF simulator 21, a hardware-in-the-loop simulator 22, and a digital operation simulator 23 are deployed to undertake the simulation of real RF signals, physical operation simulation, and digital concurrent simulation, respectively.

[0034] A unified control and data management platform 1 is established. Platform 1 is connected to each simulator and manages the running status and resource configuration of each simulator in a unified manner, including operation timing synchronization and dynamic allocation of simulation resources. When multiple simulation tasks are concurrent, Platform 1 dynamically allocates computing resources and radio frequency channels according to the load status of each simulator, and realizes operation timing synchronization through a unified clock, thereby avoiding timing conflicts and resource contention between multiple tasks and significantly improving resource utilization efficiency.

[0035] Subsequently, the mission planning subsystem 11 generates satellite communication service schemes and network planning configuration parameters through its scheme formulation module, network planning module, and network configuration module, and distributes them to each simulator. In this scenario, the solution formulation module configures the network type as a star network and the network architecture as a single center with multiple remote terminals. Technical configuration elements include Ku band, QPSK, error correction coding, and rate. The task time period determines the subsequent anomaly injection node. Link support relationships clarify the service carrying and support relationships between each site. In this scenario, central station A provides access and transfer support to remote stations B and C, and services between B and C are relayed through A, forming a primary link support relationship between A and B, and A and C. Communication link organization clarifies the setup of primary and backup links and the separation of service links and control signaling links. In this scenario, the organization is "1 QPSK service carrier + 1 dedicated signaling carrier," with the primary service link directly connecting the central station to the remote station, and the backup link relayed through adjacent remote stations. Resource usage plans the radio frequency channels, frequencies, and operating positions used between each station and the task. This scenario plans to use 2 Ku band frequencies, 3 radio frequency channels, and 5 digital terminal positions, allocated as 1 channel for the central station and 1 channel for each remote station. The network planning module completes site planning for one central station and two remote stations, link planning for uplink and downlink and the frequency points used, and channel planning for service channels and control channels. The network configuration module completes the configuration of operating parameters, subnets, service parameters, communication environment parameters (such as rainfall attenuation model and noise temperature), and fault modes (such as power amplifier failure and local oscillator lockout template) and then sends them to the three types of simulators with one click.

[0036] Platform 1 controls the access of each simulator to the communication link based on network planning configuration parameters: RF simulator 21 is connected to the RF signal link via up / down converter 41 and splitter / combiner 42; semi-physical operation simulator 22 and digital operation simulator 23 are connected to the network communication link via service channel equipment 43 and control channel equipment 44. The two links achieve signal-level interconnection via splitter / combiner 42, and Platform 1 performs unified network control of various simulators accordingly. In this scenario, Platform 1 uses splitter / combiner 42 to align and synthesize the real carrier of RF simulator 21 and the RF service signal formed by the modulation of digital and semi-physical simulator service data through service channel equipment 43 and up / down converter 41 in terms of frequency and time, and uniformly allocates frequency points (as well as the time slots or frame structures required for hybrid multiple access), so that the three types of simulators can work collaboratively as different site nodes in the same network, thereby breaking the training islands that single-form simulators can only complete single-machine operation and cannot support multi-site collaboration and cross-type networking.

[0037] Under unified network control, Platform 1 schedules various simulators to collaboratively execute satellite communication simulation operation tasks based on the satellite communication service scheme, and injects preset channel interference scenarios and equipment failure modes. Specifically, Platform 1 first creates a simulation task and loads preset scenario configurations (which include preset channel interference scenarios and equipment failure modes), and completes simulation preparation through resource configuration and operator seat configuration of each simulator. In this scenario, corresponding radio frequency channels are allocated to RF simulator 21, two operator seats are allocated to hardware-in-the-loop simulator 22, and five concurrent terminals are allocated to digital operator simulator 23, and the binding of seats to devices is completed. During the simulation, Platform 1 displays the working status and communication link status of each simulator in real time (such as the online status of each site, link signal-to-noise ratio, bit error rate, service connectivity, etc.), and dynamically injects preset channel interference scenarios and equipment failure modes according to the satellite communication service scheme. For example, when the simulation reaches the 10th minute, Platform 1 automatically triggers the channel interference scenario of "rainfall noise causing link fading" according to the task time period set in the scheme; at the 20th minute, it triggers the equipment failure mode of "remote station power amplifier failure" according to the scheme, so that the corresponding simulator enters the failure state for operators to handle. Since the timing and content of the injection are driven by the service plan and uniformly scheduled by Platform 1, the entire process does not require operators to manually switch between multiple independent systems, thus significantly improving organizational efficiency.

[0038] When scheduling and executing satellite communication simulation operation tasks, Platform 1 handles abnormal operating conditions based on preset channel interference scenarios and equipment failure modes.

[0039] First, the abnormal operating condition categories and handling procedures are configured. These categories include equipment damage, link interruption, electromagnetic interference, site failure, parameter error, and manual intervention. Electromagnetic interference and link interruption correspond to the aforementioned channel interference scenarios, while equipment damage and site failure correspond to the aforementioned equipment failure modes. The abnormal operating condition categories and handling procedures are configured based on the technical configuration elements and network type in the satellite communication service plan. Manual intervention in the aforementioned six categories refers to abnormal operating conditions manually triggered or injected by operators, distinguishing it from the channel interference scenarios and equipment failure modes automatically injected by Platform 1 according to the service plan. In this scenario, the network type is a star network, and the technical configuration elements include the Ku band. Platform 1 automatically loads a matching list of abnormal operating conditions (e.g., refining "electromagnetic interference" into subcategories such as "neighboring satellite interference" and "ground interference source") and configures corresponding handling procedures (power reduction, frequency modification, route switching, etc.) to ensure that the handling content matches the actual topology and frequency band.

[0040] Subsequently, the electromagnetic environment simulation module simulates electromagnetic environment noise and interference, including cosmic noise, antenna noise, atmospheric noise, rainfall noise, and ground noise, which can be injected individually or in combination. The rain attenuation simulation in this scenario primarily injects rainfall noise and ground noise. Each noise is superimposed onto the link according to its power spectral density, realistically reproducing the actual channel environment. This overcomes the limitations of existing systems, which can only simulate simple link interruptions and cannot simulate complex weather conditions and various types of natural noise.

[0041] The network handling module performs business anomaly handling, operational condition handling, and emergency situation handling: business anomaly handling involves rerouting and bandwidth adjustment for business interruptions and quality degradation; operational condition handling involves resetting and reconfiguring parameters for equipment operating parameter drift and abnormal status; emergency situation handling involves pre-planned handling for sudden large-scale link failures and site disconnections, so that the training content covers different levels from regular business to emergency situations.

[0042] The electromagnetic spectrum reporting module collects electromagnetic spectrum information from the FDMA integrated service network and the UHF mobile communication network and pushes it to external systems. In this scenario, it scans the occupancy and noise floor of each frequency point of FDMA in real time, generates spectrum diagrams and occupancy reports, and pushes them out to provide data support for spectrum management and analysis.

[0043] The above-mentioned handling actions are generated and issued by the intervention control module of the abnormal working condition handling subsystem 13 according to the fault category (such as the "switch to backup link" instruction for link interruption, and the "parameter reset" instruction for parameter error), to ensure that the handling is standardized and traceable.

[0044] Platform 1 establishes connections with external systems through standard interfaces. These external systems include an information and communication training and evaluation system, an information system operation and maintenance simulation system, a channel and environment simulation system, and an electromagnetic spectrum management simulation training system. Platform 1 receives training plans, scheduling instructions, and voice data from the first three systems, respectively. For example, voice data is loaded into voice services in the service link via service channel equipment 43 for trainees to conduct communication drills. The training plan is used to generate satellite communication service plans. Simultaneously, Platform 1 reports equipment status to the information and communication training and evaluation system and spectrum status to the electromagnetic spectrum management simulation training system. With the help of standardized external interfaces, Platform 1 can integrate into a wider range of collaborative training and operation and maintenance simulation environments, enabling cross-system data interaction.

[0045] Platform 1 collects task execution data (working status of each simulator, operator logs, link signal-to-noise ratio, bit error rate, connection / disconnection records, abnormal condition handling process and results, etc.), evaluates the communication performance of each simulator and generates evaluation results. The evaluation content may include link availability, service connection rate, timeliness and accuracy of abnormal condition handling, and operational standardization.

[0046] Platform 1 feeds back the evaluation results to the mission planning subsystem 11 to adjust the satellite communication service scheme and network planning configuration parameters, forming a closed loop of "execution-evaluation-feedback-optimization". In this scenario, if the evaluation finds that the bit error rate of a remote station continuously exceeds the standard under rain noise conditions and facing a star network topology, Platform 1 will automatically optimize the technical configuration elements (such as error correction coding and rate) or network planning configuration parameters (such as frequency and power) in the service scheme after feedback, and apply them in the next simulation mission. Since the evaluation data is automatically recorded by Platform 1 throughout the process and the results are automatically generated by the performance evaluation subsystem 14, the inefficiency and subjective bias caused by relying on manual recording and scoring are avoided, the consistency of the evaluation results is guaranteed, and the training quality can be continuously improved through iteration.

[0047] During the network deployment and scheduling phase, the digital station configuration module generates the corresponding digital station configuration based on the station planning parameters in the network planning configuration parameters and the network type in the satellite communication service scheme. This configuration is then sent to the digital operation simulator 23 to drive the simulator to power on the equipment and perform operational simulations. In this scenario, the station planning includes central station A, remote station B, and remote station C, with a star network type. Based on this, the digital station configuration module generates a configuration containing the three station types and their topological connections. After being sent, the digital operation simulator 23 automatically displays the corresponding station interface and completes equipment power-on and initial parameter loading, enabling operators to directly perform operational simulations on the correct station type.

[0048] Thus, this invention substantially improves satellite communication simulation in terms of realism, coverage, organizational efficiency, and training quality through signal-level interoperability of multi-mode simulators, centralized management and control of unified platform 1, standardized handling of abnormal operating conditions, and closed-loop optimization of evaluation feedback.
