Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) communication technology, and more specifically, relates to a UAV ground command and control station communication system. Background Technology

[0002] With the rapid development of UAV technology, medium-altitude long-endurance UAVs, with their core advantages of long endurance, strong payload capacity, and wide mission adaptability, have been widely used in many key fields such as disaster emergency rescue, forest fire monitoring, and border patrol and inspection, becoming one of the core equipment in modern mission execution systems. The ground command and control station, as the "central nervous system" of UAV mission execution, undertakes key functions such as telemetry data reception and analysis, remote control command generation and issuance, reconnaissance intelligence processing, and multi-seat voice coordination. The stability, integration, and data processing efficiency of its communication system directly determine the safety and effectiveness of UAV mission execution.

[0003] However, existing UAV ground command and control station communication systems still suffer from several technical bottlenecks: First, the system architecture is fragmented, with each functional module (such as telemetry processing, remote control framing, intelligence analysis, and voice communication) designed independently, lacking a unified network architecture. This results in high data interaction latency, inconsistent protocol and address planning, and difficulty in adapting to the multi-payload, multi-tasking requirements of medium-altitude long-endurance UAVs. Second, reliability design is inadequate. Traditional systems often adopt a single-link, single-device deployment mode, which makes them prone to communication link paralysis due to link interruption or equipment failure during long-endurance missions, severely impacting... Third, the level of intelligence in data processing is low. For reconnaissance data from various types of payloads such as optoelectronic reconnaissance and synthetic aperture radar, there is a lack of efficient fusion and analysis mechanisms, making it difficult to quickly and accurately extract key intelligence such as target type, location, and importance level. In addition, the remote control data does not form a clear priority sorting rule, which is prone to the risk of delay or loss of key command transmission. Fourth, the system's scalability and compatibility are poor. The functions of different positions are fixed and the hardware configurations are highly differentiated, making it difficult to flexibly adjust the roles of positions according to mission requirements. At the same time, the voice communication mode is single and cannot meet the communication needs of multiple scenarios such as intra-station collaboration and cross-platform collaboration.

[0004] Therefore, developing a unified, highly reliable, intelligent, and scalable communication system for ground command and control stations of medium-altitude long-endurance unmanned aerial vehicles (UAVs) to solve problems such as fragmented architecture, insufficient reliability, low data processing efficiency, and single communication mode in existing technologies has become a key issue that urgently needs to be addressed in the current UAV technology field. Summary of the Invention

[0005] The purpose of this invention is to propose a communication system for UAV ground command and control stations, which solves the problems of poor scalability, complex operation and maintenance, and low mission efficiency caused by the fragmented architecture, inconsistent protocols, insufficient reliability assurance, and weak multi-source data processing capabilities of existing UAV ground command and control station communication systems; and achieves a significant improvement in the system's reliability, flexibility, and intelligent information processing efficiency, thereby ensuring the flight safety of long-endurance UAVs and the efficient execution of complex tasks.

[0058] The invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0059] Example 1

[0060] like Figure 1 As shown, this embodiment provides a communication system for a UAV ground command and control station, including:

[0061] Network switching unit, data processing unit, and terminal display and control module;

[0062] Network switching units are used to build isolated link networks, service networks, and voice networks;

[0063] The data processing unit connects to the link network, service network, and voice network. It is used to parse and distribute UAV telemetry data received via the link network, frame remote control data received via the service network, fuse reconnaissance data, and encode, decode, and route voice data transmitted in the voice network.

[0064] The terminal display and control module is connected to the service network and the voice network to provide a human-machine interface for generating and sending remote control data via the service network, receiving and displaying telemetry data and intelligence information via the service network, and collecting and playing voice messages via the voice network.

[0065] Specifically, the UAV ground command and control station communication system provided in this embodiment adopts a three-layer architecture design of "network switching unit - data processing unit - terminal display and control module". Each unit has a clear division of labor and works together to build an efficient and stable communication processing system. Among them, the network switching unit, as the data transmission foundation of the system, has the core function of building mutually isolated link network, service network and voice network. Through the physical isolation of the three types of networks, it realizes dedicated transmission channels for different types of data, effectively avoiding the interaction interference between link data, service data and voice data, and providing underlying support for the security and stability of various data transmissions. The data processing unit, as the core computing hub of the system, fully connects to the above three types of networks and undertakes multi-dimensional data processing tasks: on the one hand, it connects to the link network to receive telemetry data sent by the UAV, completes parsing, splitting and targeted distribution, and ensures that the data is accurately transferred to the corresponding module; on the other hand, it receives remote control data sent by the terminal through the service network, completes frame processing according to rules and feeds it back to the link network, and at the same time receives and integrates various reconnaissance data to extract key intelligence; in addition, it is also responsible for encoding and decoding conversion and routing forwarding of voice data transmitted in the voice network to ensure smooth voice communication. As the core carrier of human-machine interaction, the terminal display and control module connects to the service network and voice network. It provides operators with an intuitive interactive interface, supports the generation and distribution of remote control data, and can receive and display telemetry data and intelligence information transmitted through the service network in real time. At the same time, it can collect and play voice data, enabling operators to easily complete operations such as issuing commands, monitoring data and coordinating voice communication, and fully meet the practical needs of UAV ground command and control.

[0066] In this embodiment, the network switching unit includes:

[0067] The link network switching module is used to connect the data link station to perform uplink and downlink data exchange between the ground command and control station and the UAV. Its hardware consists of two switches forming a link network A and a link network B that serve as backups for each other.

[0068] The business network switching module is used to build the internal business data transmission network of the ground command and control station; it transmits the business data inside the ground command and control station, and its hardware consists of two switches forming a business network A and a business network B that serve as backups for each other.

[0069] The voice network switching module is used to build the internal voice network of the ground command and control station.

[0070] Specifically, the network switching unit, as the core support for data transmission in the entire ground command and control station communication system, achieves layered deployment and efficient collaboration of link interaction, internal service transmission, and voice communication through modular design. The link network switching module specifically undertakes the crucial task of uplink and downlink data interaction between the ground command and control station and the UAV. Its core function is to establish a stable data channel between the command and control terminal and the UAV platform, providing reliable link support for downlink transmission of telemetry data and uplink transmission of remote control data. To further enhance the fault tolerance and continuity of link transmission, this module adopts a dual-switch redundancy design in its hardware configuration. Two switches with identical performance are used to form link network A and link network B respectively. The two networks serve as backups for each other and operate in parallel. When one network experiences equipment failure or link interruption, the other network can seamlessly take over the data transmission task, effectively avoiding communication paralysis caused by a single point of failure. The business network switching module focuses on the business data transmission needs within the ground command and control station. It constructs a dedicated internal business transmission network responsible for carrying various data generated by core business processes such as telemetry distribution, remote control framing, and intelligence processing, ensuring smooth data interaction between various functional modules and terminal display and control modules within the station. It also adopts a dual-switch backup architecture, with two switches forming business network A and business network B respectively. Both networks transmit business data synchronously, improving data transmission throughput and ensuring the reliability of internal business data transmission through redundancy, preventing the failure of a single switch from affecting the normal operation of the system's core business. The voice network switching module is specifically designed to build a dedicated voice network within the ground command and control station. It provides independent transmission channels for voice interaction between various positions within the station and between positions and external communication nodes, achieving physical isolation between voice data, business data, and link data. This effectively avoids mutual interference when different types of data are transmitted, ensuring the clarity and real-time performance of voice communication, and providing a stable network foundation for multi-scenario collaborative voice command.

[0071] In this embodiment, the data processing unit includes:

[0072] The telemetry distribution module has its input end connected to the link network switching module to receive the comprehensive telemetry data of the UAV transmitted by the data link station, and its output end connected to the service network switching module to distribute the parsed and split telemetry data to the terminal display and control module.

[0073] The remote control framing module has its input end connected to the terminal display and control module through the service network switching module to receive remote control commands, and to the voice communication module through the voice network switching module to receive voice data, and to the telemetry distribution module through the service network switching module to receive differential code data; its output end is connected to the link network switching module to send the framed integrated remote control data to the UAV through the data link station.

[0074] The intelligence processing module is bidirectionally connected to the terminal display and control module through the business network switching module. It is used to receive and process reconnaissance data from the terminal display and control module and return the intelligence information to the terminal display and control module.

[0075] The voice communication module is connected to the terminal display and control module and the remote control framing module through the voice network switching module. It is used to realize the functions of station, radio and collaborative intercom, as well as to transmit voice data to the data link station through the remote control framing module.

[0076] Specifically, the data processing unit, as the core computing and data processing hub of the UAV ground command and control station communication system, comprehensively undertakes the tasks of parsing, converting, processing, and forwarding various types of data through the coordinated operation of four functional modules, ensuring the accuracy and efficiency of system data flow. Among them, the telemetry distribution module undertakes the core responsibility of receiving and distributing UAV telemetry data. Its input end establishes a stable connection with the link network switching module, specifically receiving comprehensive UAV telemetry data transmitted from the data link station. This data covers multi-dimensional information such as UAV flight status and payload operation status. After receiving the data, this module performs fine-grained parsing and decomposition processing, breaking down the comprehensive telemetry data into various targeted sub-data. Then, through the service network switching module connected to its output end, it distributes the decomposed telemetry data to the terminal display and control module, providing operators with comprehensive UAV status data support. The remote control framing module focuses on the integration and forwarding of uplink control data. Its input end connects to the terminal display and control module via the service network switching module, receiving various remote control commands issued by the operator. Simultaneously, it connects to the voice communication module via the voice network switching module to obtain voice data, and then connects to the telemetry distribution module via the service network switching module to receive differential code data. After collecting all types of data, this module integrates and frames this data according to preset rules, forming a standardized comprehensive remote control data frame. This frame is then accurately transmitted to the UAV via the data link station through the link network switching module connected to its output end, achieving efficient control of the UAV. The intelligence processing module adopts a bidirectional connection design, establishing a two-way data channel with the terminal display and control module through the service network switching module. On one hand, it receives various reconnaissance data, such as electro-optical reconnaissance and synthetic aperture radar reconnaissance, transmitted from the terminal display and control module. On the other hand, it uses professional data processing algorithms to deeply analyze, fuse, and interpret the reconnaissance data, extracting key intelligence information such as target type, location, and importance level. The processed intelligence information is then transmitted back to the terminal display and control module, providing data support for command and decision-making. As the core of the system's voice interaction, the voice communication module connects with the terminal display and control module and the remote control framing module through the voice network switching module. It can not only realize three core functions: cluster intercom between various seats in the ground command and control station, cross-domain intercom with external radio stations, and collaborative intercom with the collaborative UAV platform, but also transmit various voice data to the remote control framing module, embed it in the integrated remote control data frame, and send it to the UAV through the data link station, ensuring the coordinated synchronization of voice communication and data control, and comprehensively meeting the communication needs in multiple scenarios.

[0077] In this embodiment, the telemetry distribution module includes:

[0078] The integrated telemetry data splitting submodule is used to divide the integrated telemetry data into low-speed telemetry data, high-speed telemetry data, voice data, and differential code data according to the frame identification code;

[0079] The telemetry data distribution submodule is used to send the low-speed telemetry data and high-speed telemetry data to the service network switching module via UDP multicast, wherein the low-speed telemetry data uses a unified multicast address and the high-speed telemetry data uses an independent port according to the data type; and to send the voice data to the voice communication module and the differential code data to the remote control framing module.

[0080] The telemetry data storage and playback submodule is used to store comprehensive telemetry data, low-speed telemetry data, and high-speed telemetry data by date and data type, and supports telemetry data playback function based on local storage.

[0081] Specifically, the telemetry distribution module, through the coordinated operation of three major functional sub-modules, achieves refined segmentation, targeted distribution, and full retention of UAV comprehensive telemetry data, providing reliable support for data interaction and subsequent traceability at all stages of the system. Among them, the comprehensive telemetry data segmentation sub-module, as the core of the data processing, uses the frame identification code inherent in the telemetry data frame as the distinguishing basis to accurately divide the received massive comprehensive telemetry data into four categories: low-speed telemetry data, high-speed telemetry data, voice data, and differential code data. By classifying and processing, it adapts to the transmission needs and application scenarios of different data, avoiding problems such as low processing efficiency or chaotic distribution caused by mixed data types. The telemetry data distribution submodule receives the various types of data after splitting, and adopts a differentiated distribution strategy to ensure the accuracy and efficiency of data transmission: For low-speed and high-speed telemetry data, it is sent to the service network switching module via UDP multicast. Low-speed telemetry data, due to its small data volume and similar uses, uses a unified multicast address for merging and forwarding to simplify the transmission process and reduce network overhead. High-speed telemetry data, due to its large data volume, high real-time requirements, and diverse types, is allocated independent UDP port numbers according to specific data types to ensure that various high-speed data transmissions do not interfere with each other. At the same time, this submodule sends the split voice data to the voice communication module to provide data support for voice interaction, and accurately transmits differential code data to the remote control framing module to ensure the integrity of remote control command framing. The telemetry data storage and playback submodule focuses on the long-term retention and retrospective utilization of data. It systematically stores the original comprehensive telemetry data, the split low-speed telemetry data, and the high-speed telemetry data according to the dual classification rule of "date + data type", ensuring the orderliness and integrity of data archiving. At the same time, it supports the playback function based on locally stored data, which can retrieve historical telemetry data on demand for reproduction, providing important data traceability basis for scenarios such as UAV flight status analysis, mission review, and fault diagnosis.

[0082] In this embodiment, the remote control framing module includes:

[0083] The remote control data receiving and display submodule is used to receive remote control data, differential code data and voice data, and to display the sender's seat number, remote control data type and remote control data transmission quantity.

[0084] The remote control data framing and forwarding submodule is used to perform legality verification on remote control data according to the seat role allocation instruction and seat role information table, and to frame the remote control data, differential code data and voice data that have passed the legality verification into a comprehensive remote control data frame according to the set priority order, and forward it to the data link station through the link network switching module via UDP multicast.

[0085] The log file recording submodule is used to store remote control data by date and instruction type, as well as to store integrated remote control data frames by date.

[0086] Specifically, the remote control framing module, as the central hub for uplink command and control instructions, undertakes the core task of aggregating, managing, framing, and transmitting multi-source control and communication data. Its function is achieved collaboratively by three sub-modules. The remote control data receiving and display sub-module serves as the module's data entry point and monitoring interface. It simultaneously receives remote control data from various operating positions within the station, differential code data from the positioning system, and voice data from the communication system. It displays key information such as the sending position, instruction type, and transmission quantity in real time on the software interface, providing commanders with intuitive uplink instruction flow monitoring capabilities. The remote control data framing and forwarding submodule is the core processing unit. It first performs rigorous legality verification on received remote control commands based on the system's assigned seat roles and the internally maintained seat role information table. This ensures the correctness and security of command authority, preventing unauthorized or excessive control. Subsequently, it sorts and integrates the verified remote control data, differential code data, and voice data according to a preset priority rule of "flight control priority, critical data priority," assembling them into a unified, wirelessly channel-compatible integrated remote control data frame. Finally, this data frame is transmitted to the data link station via a highly reliable link network switching module through an efficient UDP multicast method, and then uploaded to the UAV. The log file recording submodule runs throughout the entire process, providing comprehensive data traceability and auditing functions. It stores all original remote control data according to date and command type, and archives each issued integrated remote control data frame by date, providing an immutable data foundation for subsequent operational review, fault analysis, and system optimization. Through the precise coordination of these three sub-modules, the remote control framing module achieves fully automated and highly reliable management of the entire process of uplink command reception, verification, integration, transmission, and recording.

[0087] In this embodiment, the intelligence processing module includes:

[0088] The payload reconnaissance data receiving submodule is used to receive reconnaissance data from the terminal display and control module forwarded by the service network switching module via UDP multicast. Different UDP multicast port numbers correspond to different types of reconnaissance data.

[0089] The intelligence target analysis submodule is used to analyze reconnaissance data through an intelligent reasoning model to obtain intelligence information including target type, location, and level.

[0090] The intelligence data distribution submodule is used to distribute intelligence information to the corresponding seats of the terminal display and control module via the business network switching module through UDP multicast. Different UDP multicast port numbers correspond to different types of intelligence information and seats.

[0091] Specifically, the intelligence processing module, through the orderly connection of three sub-modules, achieves accurate reception, intelligent analysis, and targeted distribution of various types of payload reconnaissance data, providing efficient and reliable intelligence support for command and decision-making. The payload reconnaissance data receiving sub-module employs UDP multicast transmission and specifically receives various types of reconnaissance data from the terminal display and control modules, forwarded by the service network switching module. This includes electro-optical reconnaissance videos, electro-optical reconnaissance images, synthetic aperture radar reconnaissance images, and collaborative message data. To ensure the accuracy and orderliness of data reception, this sub-module assigns independent UDP multicast port numbers to different types of reconnaissance data, effectively avoiding analysis confusion caused by mixed reception of different reconnaissance data and ensuring the high efficiency and stability of the data reception process. The intelligence target analysis submodule, as the core data processing link, is equipped with a professional intelligent inference model. After receiving various reconnaissance data, it inputs multi-source heterogeneous reconnaissance data into the model for deep fusion and inference analysis. Through the model's accurate identification and analysis of target features, it extracts key intelligence information from complex reconnaissance data, specifically including target type, target geographical location, and target importance level. This achieves the transformation from raw reconnaissance data to effective intelligence, significantly improving the efficiency and accuracy of intelligence extraction. The intelligence data distribution submodule continues the high-efficiency transmission characteristics of UDP multicast, distributing the parsed intelligence information to the corresponding seats of the terminal display and control modules via the business network exchange module. It also adopts a differentiated port design, assigning dedicated UDP multicast port numbers to different types of intelligence information and seats with different functions, ensuring that various intelligence information can be accurately matched to the corresponding operation seats, allowing relevant operators to obtain the required intelligence in a timely manner, providing timely and accurate basis for subsequent task decisions and command issuance.

[0092] In this embodiment, the voice communication module includes:

[0093] Multi-band radio and communication network controller;

[0094] The communication network controller is used to select and control the voice channel and communication mode, specifically supporting trunk intercom mode, radio intercom mode and collaborative intercom mode.

[0095] Among them, the trunking intercom mode is used to realize voice broadcast communication between various seats in the ground command and control station through the voice network switching module; the radio intercom mode is used to conduct two-way voice communication with external radios through multi-band radios; and the collaborative intercom mode is used to embed voice data into integrated remote control data through the remote control framing module.

[0096] Specifically, the voice communication module, serving as the physical implementation and logical control center for voice services in the command and control station, is primarily composed of two hardware components: a multi-band radio and a communication network controller. The latter enables intelligent integration and seamless switching between three communication modes. The multi-band radio is the key radio frequency device for interconnecting the module with external wireless communication networks. It is responsible for transmitting and receiving voice signals with the superior command post, neighboring units, or other external radios on specific radio frequency bands, acting as the physical bridge for the system to achieve beyond-line-of-sight, long-distance voice communication. The communication network controller is the "intelligent brain" and switching core of the entire voice communication module. It undertakes the most critical system control and signal processing functions, mainly including two aspects: first, the dynamic allocation and management of voice channels to ensure the orderly and conflict-free transmission of multiple voice data streams; and second, the selection and control of the three core communication modes: trunking intercom, radio intercom, and collaborative intercom. Operators can select the desired mode through the software interface, and the controller automatically switches internal data routing and signal processing according to instructions.

[0097] In trunked intercom mode, the controller broadcasts voice data from a specific seat across the station's voice network via the voice network switching module, enabling real-time internal communication between all seats. In radio intercom mode, the controller acts as a encoding / decoding and signaling adaptation hub: in the receiving direction, it demodulates and decodes the wireless voice signals received from multi-band radios, converting them into digital voice streams before sending them to the target seat; in the transmitting direction, it encodes and modulates the digital voice transmitted by the seats before transmitting it through multi-band radios, thus establishing a clear and stable two-way voice link with external radios. In collaborative intercom mode, the controller achieves voice fusion with the UAV data link: it highly compresses and encodes the digital voice transmitted by the station's seats with low latency, then outputs it to the remote control framing module; the remote control framing module embeds this voice data as a special type of instruction into the uplink integrated remote control data frame, which is then sent to other platforms within the air formation via the UAV data link, thus achieving cross-UAV platform voice collaborative communication. Simultaneously, the controller is also responsible for processing the collaborative voice decoded from the downlink data link. Through this architecture of "dedicated hardware (radio) + intelligent controller (hardware and software combination)," the module integrates three distinct voice communication needs—internal collaboration, external communication, and cross-platform communication—into a single, efficient, reliable, and controllable physical platform.

[0098] In this embodiment, the terminal display and control module includes:

[0099] At least five seats, which can be software-defined as three roles: link monitoring seat, flight monitoring seat, and mission monitoring seat;

[0100] Each seat includes a ruggedized computer, an all-in-one computer, and a voice terminal;

[0101] Both the ruggedized computer and the all-in-one computer connect to service network A and service network B respectively via dual network cards;

[0102] All voice terminals are connected to the voice network switching module to generate voice data;

[0103] The link monitoring station is equipped with link monitoring software, which is used to parse and display link telemetry data, and send link control commands and station role assignment commands.

[0104] The flight monitoring station is equipped with flight monitoring software, which is used to parse and display flight status telemetry data and send flight control commands;

[0105] The mission monitoring station is equipped with mission payload display and control software, which is used to parse and display payload telemetry data, send payload control commands, send reconnaissance data obtained from parsing payload telemetry data to the intelligence processing module, and receive intelligence information returned by the intelligence processing module.

[0106] Specifically, the terminal display and control module, as the core carrier of human-computer interaction, comprehensively supports various operational needs of UAV command and control with its flexible and configurable seat design and redundant and reliable hardware access methods. This module is configured with at least five functional seats, breaking through the limitations of traditional fixed seat functions. Through software definition, it can flexibly switch between three roles: link monitoring seat, flight monitoring seat, and mission monitoring seat. It can quickly adjust seat function allocation according to the needs of different mission scenarios, improving the system's adaptability and flexibility. Each seat adopts a "dual computer + voice terminal" hardware configuration, including one ruggedized computer, one all-in-one computer, and one voice terminal. The ruggedized computer and the all-in-one computer maintain consistent hardware performance and software operating environment, providing dual protection for data processing and display. To ensure the reliability of business data transmission, both computers are equipped with dual network cards, connecting to two mutually backup networks, namely business network A and business network B, respectively, to achieve dual-path parallel transmission of business data and avoid data interruption caused by single network failure. All seats' voice terminals establish a stable connection with the voice network switching module, specifically responsible for voice data acquisition and generation, providing hardware support for multi-scenario voice communication. In terms of functional adaptation, different roles are precisely empowered through dedicated software: the link monitoring station is equipped with link monitoring software, which can analyze and intuitively display link telemetry data, and support operators to issue link control commands and station role assignment commands, providing an operation entry point for system network configuration and station management; the flight monitoring station is equipped with flight monitoring software, which focuses on analyzing and displaying the UAV's flight status telemetry data, and can send flight control commands such as pitch control and throttle control to achieve real-time control of the UAV's flight attitude; the mission monitoring station is equipped with mission payload display and control software, which is responsible for analyzing and displaying payload telemetry data, sending payload control commands to regulate the working status of payload equipment, and sending reconnaissance data such as electro-optical reconnaissance and synthetic aperture radar reconnaissance obtained from analyzing payload telemetry data to the intelligence processing module, while receiving and displaying key intelligence information such as target type and location returned by the intelligence processing module, providing a complete data support closed loop for mission decision-making and payload control.

[0107] In this embodiment, the low-speed telemetry data includes: flight status telemetry data, fire control status telemetry data, communication link status telemetry data, optoelectronic payload status telemetry data, cooperative status telemetry data, cooperative voice data, differential code data, and synthetic aperture radar status telemetry data.

[0108] High-speed telemetry data includes: UAV forward view image data, electro-optical reconnaissance equipment image data, electro-optical reconnaissance equipment video data, and synthetic aperture radar image data;

[0109] Remote control data includes: flight control remote control data, fire control remote control data, electro-optical remote control data, synthetic aperture radar remote control data, and cooperative remote control data;

[0110] The reconnaissance data includes: electro-optical reconnaissance video, electro-optical reconnaissance images, synthetic aperture radar reconnaissance images, and cooperative message data.

[0111] In this embodiment, the priority order is as follows:

[0112] Flight control remote control data > Differential code data > Fire control remote control data > Optoelectronic remote control data = Synthetic aperture radar remote control data = Cooperative remote control data = Voice data.

[0113] Example 2

[0114] like Figure 2 As shown, this embodiment provides a communication system for a UAV ground command and control station, including:

[0115] The system includes a link switching module, a telemetry distribution module, a remote control framing module, a voice switching module, a service switching module, an intelligence processing module, a voice communication module, and a terminal display and control module.

[0116] The link network switching module is used for data exchange between the data link station and the command and control station. The hardware equipment uses link network switch A and link network switch B, which serve as backups for each other.

[0117] The telemetry distribution module includes: a comprehensive telemetry data splitting submodule, which receives comprehensive telemetry data forwarded by the link switching module and divides the comprehensive telemetry data into two main categories: low-speed telemetry data and high-speed telemetry data according to different telemetry data frame identification codes. The telemetry data distribution submodule then sends the split telemetry data to the service switching module using UDP multicast. Low-speed telemetry data is forwarded using a unified multicast address and port number, while high-speed telemetry data is distinguished using separate UDP port numbers based on its data type. The telemetry data storage and playback submodule is used to classify and save the integrated telemetry data received from the service exchange submodule into local folders according to date, and to classify and save the split telemetry data into local folders according to type and date. The telemetry data in the local folders is used for playback, providing a foundation for UAV flight data analysis. All types of split data are sent using UDP multicast, with different multicast addresses and port numbers used to distinguish between different types of telemetry data. The specific distribution process for the various types of telemetry data is as follows: high-speed and low-speed telemetry data are forwarded through the service exchange module and finally parsed and displayed in the terminal display and control module; voice data is forwarded through the voice exchange module and finally sent to the voice communication module; differential code data is sent to the remote control framing module.

[0118] The remote control framing module includes: a remote control data receiving and display submodule, used to receive flight control remote control data, fire control remote control data, electro-optical remote control data, synthetic aperture radar remote control data, and cooperative remote control data sent by the terminal display and control module; receive differential code data sent by the telemetry distribution module; and receive voice data sent by the voice communication module. The interface displays the remote control data sender's seat number, remote control data type, and the number of remote control data frames sent. The remote control data framing and forwarding submodule is used to assemble valid data frames into a comprehensive remote control data frame according to priority before forwarding. Specifically: it receives seat role allocation instructions sent by the link seat and records the seat role table; compares the received telemetry data with the UAV number, seat number, and software number in the seat role table, filters out invalid remote control data, and frames the valid remote control data according to the following priority order: flight control remote control data > differential code data > fire control remote control data > electro-optical remote control data = synthetic aperture radar remote control data = cooperative remote control data = voice data. The framed comprehensive remote control data frame is sent to the link switching network using UDP multicast and finally forwarded to the line-of-sight link station. The log file recording submodule is used to store the received flight control remote control data, fire control remote control data, electro-optical remote control data, synthetic aperture radar remote control data, and cooperative remote control data in a local file according to the date and control command type. At the same time, it stores the framed integrated remote control data frame in a local file according to the date.

[0119] The intelligence processing module includes: a payload reconnaissance data receiving submodule, used to receive reconnaissance data sent by the payload positions in the terminal display and control module, specifically including electro-optical reconnaissance images, electro-optical reconnaissance videos, synthetic aperture radar (SAR) reconnaissance images, and cooperative reconnaissance data. It receives various types of reconnaissance data using UDP multicast, using different UDP multicast port numbers to distinguish the data types. An intelligence target parsing submodule is used to send electro-optical reconnaissance images, electro-optical reconnaissance videos, and SAR reconnaissance videos to an intelligent inference model for inference and parsing, ultimately outputting reconnaissance intelligence data, including target type, target geographical location, and target importance level. An intelligence data distribution submodule is used to distribute the parsed intelligence information to the payload positions in the terminal display and control module. It sends intelligence data using UDP multicast, distinguishing different types of intelligence data through different port numbers, ensuring that the payload positions in the terminal display and control module can receive the corresponding reconnaissance intelligence data.

[0120] The voice communication module includes: a trunking intercom submodule, used for voice communication between multiple seats in the terminal display and control module; the communication network controller broadcasts voice data received from the voice terminals within the voice network, enabling communication between voice terminals on multiple seats within the command and control station. A radio intercom submodule, used for communication between voice terminals on seats and remote radios; the voice data transmission process involves encoding the raw voice data received from the voice terminals in the communication network controller and then sending it to the multi-band radio; the voice data reception process involves receiving voice data from the multi-band radio, decoding it, and then sending it to the voice terminals, enabling radio communication between the command and control station and the superior command post. A collaborative intercom submodule, used for communication between voice terminals and remote UAV platforms within the network using an airborne collaborative data link; the voice data reception process involves the communication network controller receiving voice data sent by the telemetry distribution module, decoding the received voice, and then sending it to the designated voice terminal.

[0121] Each seat in the terminal display and control module contains one voice terminal. The voice terminals, main data server, backup data server, and communication network controller in the voice communication module are networked through the voice network switch in the voice switching module. The voice terminal is responsible for voice acquisition and sending it to the voice network using UDP multicast. The communication network controller is responsible for compressing / decompressing / decoding the received voice data and sending it to the designated location according to the selected voice function. Taking voice uplink as an example, the specific data transmission flow is as follows: In the trunked intercom mode, the voice data acquired by the voice terminal in this seat is directly broadcast to the voice terminals in other seats; in the radio intercom mode, the raw voice data acquired by the voice terminals in the seat is sent to the communication network controller for voice encoding, and after being relayed by multi-band radios, it is finally sent to the superior command post; in the collaborative dialogue mode, the raw data acquired by the voice terminals in the seat is sent to the communication network controller for voice encoding, and after being relayed by the voice network, it is sent to the remote control framing module. The voice data is then combined into a unified remote control data frame and sent to the data link station.

[0122] The terminal display and control module includes:

[0123] The ground command and control station has five positions, divided into three roles: link control, flight control, and mission control. Each position has identical hardware, and role allocation is software-defined and interchangeable. Each position's hardware consists of: one ruggedized computer (…). Figure 2 (mainframe), 1 all-in-one computer Figure 2 The ruggedized computer and the all-in-one computer have the same operating system version, software operating environment and deployment software.

[0124] The ruggedized computers and integrated computers in each workstation are integrated into the service network, and the voice terminals are connected to the voice network. To ensure communication reliability, the data service system, intelligence target interpretation equipment, ruggedized computers, and integrated computers use two mutually redundant networking methods: service network A and service network B. Therefore, each ruggedized computer and integrated computer uses two network cards, one for service network A and one for service network B, to realize the uplink and downlink forwarding of service data within the command and control station. The voice terminals and communication network controllers in the five workstations form the voice network, used to realize voice communication in different modes in the voice communication module. Different workstations use the same UDP multicast address and port number to send remote control commands to the remote control framing module; they use different UDP multicast port numbers to receive different types of telemetry data. The functions of the workstations are described below according to the roles of three types of workstations: link monitoring workstation, flight monitoring workstation, and mission monitoring workstation.

[0125] The link monitoring station, equipped with link monitoring software installed in all-in-one and ruggedized computers, displays data link status data and sends remote control commands. It first parses the telemetry data sent from the telemetry distribution module and displays it in the status display area of ​​the link monitoring software. Then, it sends remote control commands and station role allocation commands in the command sending area of ​​the link monitoring software. Link telemetry data includes: C-band uplink voltage, modulation method, communication status, and channel number; C-band downlink voltage, modulation method, communication status, and channel number; L-band uplink voltage, modulation method, communication status, and channel number; L-band downlink voltage, modulation method, communication status, and channel number. Link remote control data includes: C-band operating status settings, uplink / downlink power settings, channel number settings, and uplink / downlink rate settings; L-band operating status settings, uplink / downlink power settings, channel number settings, and uplink / downlink rate settings. The station role allocation command includes the UAV number, station number, and software number, providing a basis for the remote control framing module to record and maintain the station role information table.

[0126] The flight monitoring station, equipped with a ruggedized computer and an all-in-one computer, installs flight monitoring software to parse flight control status telemetry data sent by the data service module and display it in the data display area of ​​the flight monitoring software; it also sends flight control commands to the remote control framing module. Flight status telemetry data includes: position, altitude, airspeed, ground speed, pitch, roll, yaw, voltage, current, cylinder temperature, propeller speed, remaining fuel, link status, and fault status words; flight control commands include: payload power-up / down control, pitch control, roll control, heading control, throttle control, onboard equipment control, and navigation command and control.

[0127] The mission payload station has a ruggedized computer and an all-in-one computer installed with optoelectronic fire control integrated software, synthetic aperture radar display and control software, and collaborative equipment display and control software, respectively. These software are used to analyze and display telemetry data of specified types of payload data and send specified types of remote control command data when performing different tasks.

[0128] In this embodiment, the downlink telemetry data transmission is as follows: the command and control station forwards the integrated telemetry data sent by the data link station to the telemetry distribution module through the link switching module. The telemetry distribution module splits the telemetry data according to the service type and forwards it to different role seats in the terminal display and control module through different UDP multicast addresses via the service network switching module. Different seats parse the telemetry data as needed according to their roles and display it in the corresponding status display area. The uplink remote control data transmission is as follows: different role seats in the terminal display and control module send corresponding remote control commands, which are forwarded to the remote control framing module through the service network switching module. The remote control framing module frames the remote control commands into integrated remote control command frames according to their priority and sends them to the line-of-sight link station through the link switching module. Both remote control and telemetry data forwarding use UDP multicast, enabling different seats to receive multiple types of telemetry data simultaneously. The telemetry data is then parsed and displayed as needed according to the seat role. To ensure the reliability of data transmission, both the link network switching module and the amateur network switching module use two backup switches.

[0129] like Figure 3 As shown, the implementation process of remote control framing for medium-altitude long-endurance UAVs in this embodiment is as follows:

[0130] Configuration file judgment: After the remote control framing software starts, the currently running data service unit searches for the UAV serial number configuration file at a fixed location. The configuration file records the correspondence between the UAV type, UAV serial number and UAV onboard number. It distinguishes the UAV platform in the sent integrated remote control data, providing a basis for the ground command and control station to control two UAVs simultaneously. If the configuration file exists, it reads the configuration information in the file. If the configuration file does not exist, it saves the default data as the configuration file.

[0131] Data Analysis: The remote control framing software receives differential code data sent by the telemetry distribution module, flight control and payload remote control data sent by the terminal display and control module, and voice data sent by the voice communication module. Since the data volume of each type is relatively small, the remote control framing software receives all types of data using the same UDP multicast and port number, and different data types are distinguished using different frame identifiers.

[0132] Seat allocation parsing: Receives seat allocation data frames sent by the link monitoring seats in the terminal display and control submodule. These data frames contain seat roles corresponding to different seats. The seat role allocation table is stored in memory and updated each time a seat allocation data frame is received.

[0133] Seat Number Validity Check: This function checks the validity of the seat number, software number, and UAV onboard number in the flight control remote control data frames and payload remote control data frames sent by the terminal display and control module. This allows designated seats to send specific types of remote control data to specific aircraft models. Data is discarded directly if the check fails.

[0134] Data framing: The flight control remote control data, payload remote control data, voice data and differential code data that have passed the legality test are stored in different memory queues to provide a basis for subsequent data framing.

[0135] Interface display: The interface display area of ​​the remote control framing software consists of a seat configuration information display area and a data transmission and reception statistics display area. The parsed seat role information is displayed in the seat configuration information display area, and the type and quantity of remote control data received and the number of comprehensive remote control data frames are displayed in the data transmission and reception statistics display area.

[0136] Data framing: After retrieving telemetry data from queues of different data types in memory, the data is prioritized in the order of flight control remote control > differential code data > payload remote control = voice data to form a comprehensive telemetry data frame, which is then sent to the line-of-sight link station via the link network switching module.

[0137] like Figure 4 As shown, the data processing flow of the telemetry distribution module is as follows:

[0138] Telemetry data parsing: The received integrated telemetry data frames are divided into four categories according to different frame identifiers: low-speed telemetry data, electro-optical reconnaissance video data, synthetic aperture radar image data, and forward-view image data. Different types of data are distinguished by different frame headers. Low-speed telemetry data integrates multiple low-speed telemetry data with smaller data volumes, specifically including flight control telemetry data, electro-optical telemetry data, synthetic aperture radar status data, cooperative voice data, and link telemetry data.

[0139] Telemetry data distribution: The parsed telemetry data of various types is sent to the service network in the service exchange module. The telemetry data is sent using UDP multicast. The four types of data, namely low-speed telemetry data, photoelectric reconnaissance video data, synthetic aperture radar image data, and front view image data, are distinguished by different port numbers. This provides a basis for different seats in the terminal display and control module to receive data according to their needs using the corresponding multicast addresses and port numbers.

[0140] Telemetry data recording: The received integrated telemetry data frames are classified by date and saved to a local folder; at the same time, the parsed low-speed telemetry data, electro-optical reconnaissance video data, synthetic aperture radar image data, and forward view image data are classified by time and data type and saved to a local folder, providing a basis for subsequent telemetry data analysis through playback mode.

[0141] like Figure 5 As shown, the voice data transmission process of the voice communication module is as follows:

[0142] Voice channel selection: The voice terminals of different workstations in the terminal display and control submodule are distinguished by channel number. The communication network controller records the corresponding number of the voice terminal, providing a basis for the intercom party to talk to the designated workstation. It enables the voice terminal in the workstation to send a channel request message to the communication network controller. The communication network controller records and judges the requested channel number. If the channel is not occupied, it assigns a channel number to the voice terminal. If the channel is occupied, the voice channel is reassigned.

[0143] Voice mode selection: The voice terminal can select three call modes: group intercom mode, radio intercom mode, and collaborative intercom mode.

[0144] The cluster intercom mode is used for intercom between different seats in the ground command and control station. Specifically, the voice data is first collected through the voice terminal, and then the raw voice data is sent to the voice network using UDP multicast. The voice terminals on the other seats receive the data and play it.

[0145] In radio intercom mode, the voice terminal on the workstation sends the collected voice data to the communication network controller in the voice network. The communication network controller is responsible for compressing and encoding the collected raw data, and then sending the compressed and encoded voice data to the multi-band radio. The communication peer radio receives the voice data and performs de-encoding, decompression, and voice playback.

[0146] In the collaborative intercom mode, the voice data transmission process is as follows: the voice terminal on the workstation first sends the collected voice data to the communication network controller. The communication network controller is responsible for compressing and encoding the collected raw data, sending the compressed and encoded voice data to the remote control encoding module, and then framing the voice data into a remote control integrated data frame before sending it.

[0147] like Figure 6 As shown, the data processing flow of the intelligence processing module is as follows:

[0148] Data reception: Receives reconnaissance data sent from different seats in the terminal display and control submodule, including electro-optical reconnaissance video, electro-optical reconnaissance images, synthetic aperture radar reconnaissance images, and cooperative message data. It uses UDP multicast to receive various types of reconnaissance data in the service network, distinguishing the reconnaissance data types through different multicast port numbers.

[0149] Target message parsing: Based on the protocol, the received collaborative message data is parsed to determine the target type, target location, and target importance level, providing a basis for adding collaborative targets to the intelligence data in subsequent reconnaissance.

[0150] Target detection / target level classification / geographic coordinate calculation: The data obtained by feature layer fusion of electro-optical reconnaissance images and synthetic aperture radar images is loaded into the inference model, and the target type in the final output image is marked using a rectangle. The target location is marked with the target type in the upper right corner of the rectangle. The target importance level is classified according to the target type: core, important and general. The geographic coordinates of the target are calculated using the position and attitude data of the UAV platform and the attitude data of the electro-optical reconnaissance payload. Finally, the target type and location are added to the image based on the parsed target message, and the specific location is matched on the image based on the geographic coordinates of the target message.

[0151] Target transmission: The parsed video data, image data, and message data are sent to multiple workstations on the terminal display and control module. Data is sent using UDP multicast, and different data types are distinguished by port numbers. Workstations receive data and display information according to their workstation roles.

[0152] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
