Description

Technical Field

[0001] This invention belongs to the field of aerial observation and geophysical exploration technology, specifically relating to an aerial platform search and rescue system and method. Background Technology

[0002] While the existing King Air 350ER maritime search and rescue aircraft already possesses basic equipment such as electro-optical pods, search radar, AIS (Automatic Identification System) and satellite communication, the system is mainly operated manually with a single aircraft and single payload. It has key shortcomings such as the need for manual route planning, the reliance on human interpretation for target identification and information downlink, the lack of integration between mission payload and navigation, the lack of intelligent search and rescue procedures for typical scenarios, the inability to perform material drop operations, the single communication link without backup, and the lack of hot standby redundancy for the core processor. As a result, its autonomy, intelligence, adaptability, and reliability in complex scenarios are all insufficient. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an airborne platform search and rescue system and method. The search and rescue system is a multi-purpose, large fixed-wing aircraft integrating emergency search and rescue and cruise monitoring. It is equipped with remote sensing payloads such as radar, optoelectronic (visible light, infrared), and satellite communication, as well as rescue supplies and delivery equipment, supporting target detection under nighttime, rain, snow, and high sea state conditions. The search and rescue method employs onboard collaborative mission management and multi-payload collaborative observation technology centered on intelligent target perception and intelligent auxiliary decision-making. This enables automatic and autonomous execution of search and rescue missions, rapid and accurate location of distressed targets, real-time delivery of rescue supplies, and real-time relay of disaster information, providing auxiliary decision-making support for ground command centers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An airborne platform search and rescue system includes an airborne platform subsystem, a display and control subsystem, a payload subsystem, a communication subsystem, and a power supply system. The airborne platform subsystem is a large fixed-wing aircraft that integrates and installs the equipment of the other subsystems, and is used to carry the equipment of the subsystems and plan search and rescue flight routes. The display and control subsystem is used to implement mission loading, route planning, display management, equipment control, intelligent processing, decision support, database, and third-party program management functions. The payload subsystem is used to acquire radar, visible light, infrared, ship automatic identification system, or radio information of the search area when performing search and rescue missions, to deploy rescue supplies upon reaching the rescue location, and to acquire the latitude, longitude, altitude, speed, attitude, and wheel load information of the airborne platform in real time, and to send the above information to the display and control subsystem in real time. The communication subsystem is used for communication between the display and control subsystem and the ground station, to receive text or voice dispatch instructions from the ground station, and to transmit intelligent identification results, decision support information, and equipment status information to the ground station. The power supply system is used to provide DC power during the execution of search and rescue missions.

[0006] The present invention also provides a search and rescue method for an aviation platform search and rescue system, comprising the following steps:

[0007] Step 1: Activate the display and control subsystem according to the received search and rescue instructions, select the corresponding typical application scenario and select the target type to start the task;

[0008] Step 2: Call the display management module, backend database and task binding module to bind the search and rescue airspace range, target search range, target type and auxiliary information into the backend database;

[0009] Step 3: The route planning module automatically generates the system task route based on the binding information, and after manual confirmation, it forms the route.

[0010] Step 4: The aerial platform flies to the search area according to the mission route, and each search payload completes parameter configuration and enters the corresponding working mode under the control of the display and control subsystem;

[0011] Step 5: The multi-functional radar and / or photoelectric turret acquires target information and transmits it back to the display and control subsystem in real time. The display and control subsystem calls the auxiliary decision-making module and intelligent processing module to perform target recognition and generate recognition result information.

[0012] Step 6: The identification results are sent to the ground station in real time via the communication subsystem for synchronous display, providing a basis for decision-making in search and rescue command.

[0013] Step 7: After the task is completed, save the work log and data, shut down all equipment, and return the aviation platform according to the predetermined route.

[0014] Beneficial effects:

[0015] This invention achieves efficient all-weather, cross-scenario rescue through "multi-load collaboration + intelligent decision-making":

[0016] 1. Mission adaptability: Covering multiple scenarios such as maritime disasters, floods, earthquakes, and forest fires, it integrates multiple functions such as emergency search and rescue, cruise monitoring, and real-time communication, and can achieve continuous operation day and night and in severe weather with radar / photoelectric / infrared payloads.

[0017] 2. Automation and Intelligence: The entire process from task management and route planning to target identification and decision support is automated; AI technologies such as multimodal fusion, diffusion model, and feature pyramid are introduced to achieve intelligent search for ships / personnel, precise delivery of supplies, and automatic detection of water boundaries. The search strategy for small targets is optimized, and the results of artificial intelligence processing and expert experience and knowledge are combined to form an intelligent extraction method for decision support, so as to achieve rapid and accurate target positioning.

[0018] 3. Security and Reliability: Employing dual-active hot standby redundancy and a small distributed computing cluster, the system achieves zero interruption in the event of a single point of failure. Each control console corresponds to a task processor, forming a hot backup protection mechanism. If one task processor fails, the other immediately takes over all functions, significantly reducing the overall system failure rate. Furthermore, the entire system comprises two task processors, one switch, one shared storage device, one integrated interface processor, one communication link management unit, and various payloads, forming an onboard small distributed computer cluster. This allows for flexible integration of more computing devices or peripheral payloads, with multiple graphics cards enabling parallel processing to accelerate intelligent target search. A reinforced structure ensures stable operation under high temperature, high pressure, and high vibration conditions.

[0019] 4. Human-computer interaction: Provides an intuitive and easy-to-use display and control interface and a supporting training system, significantly reducing operational complexity and improving response speed. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1 As shown, an aviation platform search and rescue system of the present invention includes an aviation platform subsystem, a display and control subsystem, a payload subsystem, a communication subsystem, and an electronics supply system.

[0025] The aviation platform subsystem uses a large fixed-wing aircraft, which undergoes structural modifications. The seats inside the cabin are removed, and standard equipment cabinets, power distribution cabinets, control consoles, and seats are installed. Matching electrical interfaces, wiring boxes, negative line boards, etc. are installed on the floor and bulkheads. It is equipped with 10 observation windows of 6 types. An antenna radome and pod are added outside the cabin, and equipment fixing components are added. It can complete the integration and installation of other subsystems, and is used to carry the equipment of the subsystems and complete the flight of the planned search and rescue route.

[0026] Preferably, a dual-active hot standby redundancy and a small distributed computing cluster are adopted to ensure zero interruption in the event of a single point of failure; each of the left and right control consoles corresponds to a task processor, forming a hot backup protection mechanism. If one task processor fails, the other task processor immediately takes over all functions, which greatly reduces the failure rate of the entire system.

[0027] The display and control subsystem includes a task processing computer, an integrated data management device, a shared storage device, a switch, a multi-screen display, a handheld device, and a keyboard. The task processing computer is used to implement functions such as task binding, route planning, display management, equipment control, intelligent processing, decision support, database and third-party program management. The integrated data management device is used to store image information output by the search payload and processed target information. The shared storage device is used to back up the subsystem database information in real time. The switch can establish a local area network interconnection between devices via Ethernet for real-time high-speed transmission of instructions and data information between devices. The multi-screen display is used to display multi-dimensional information such as task planning settings, task navigation management, multi-payload monitoring, and target area status in the monitoring software in real time. The handheld device and keyboard are used to implement functions such as equipment control and external information input.

[0028] The payload subsystem includes a multi-functional radar, an electro-optical turret, an Automatic Identification System (AIS) device, a rescue radio, a rescue material delivery device, and an interface processor. It is used to acquire radar, visible light, infrared, AIS, or radio information of the search area when performing search and rescue missions, to complete the delivery of rescue materials when arriving at the rescue location, to acquire real-time information such as latitude, longitude, altitude, speed, attitude, and wheel load of the aviation platform, and to send the above information to the display and control subsystem in real time. The multi-functional radar can operate in various modes, including Maritime Wide Area Target Search (WAS) and Synthetic Aperture Radar (SAR) / Inverse Synthetic Aperture Radar (ISAR) imaging, to acquire radar imaging information of the search area. The electro-optical turret has visible light, shortwave infrared, mid-wave infrared, and laser search modules, which can acquire visible light and infrared image information of the ground in real time. The AIS equipment is used to receive AIS information from ships at sea within the signal coverage area in real time. The rescue radio is used to receive distress signals from rescue radios of ships at sea within the signal coverage area in real time. The rescue material delivery equipment is used to deliver rescue materials such as life jackets and lifeboats from the fuselage delivery window when arriving at the rescue location. The interface processor is used to receive data from RS232, RS422, ARINC818 and other payload and flight platform interfaces, and converts the signal data into IP packets and forwards them to the display and control subsystem via Ethernet.

[0029] The communication subsystem includes satellite communication equipment, aircraft-to-ground communication equipment, BeiDou navigation equipment, VHF radio, and a communication link management unit. It is used for communication between the display and control subsystem and the ground station, receiving text or voice dispatch commands from the ground station, and transmitting intelligent recognition results, auxiliary decision-making information, and equipment status information to the ground station. The satellite communication equipment establishes a communication link between the aircraft platform and the communication satellite, enabling information transmission between the display and control subsystem and the ground station. The aircraft-to-ground communication equipment establishes a direct line-of-sight communication link between the aircraft platform and the ground station, enabling information transmission between the display and control subsystem and the ground station. The BeiDou navigation equipment receives BeiDou navigation satellite signals and provides time, position, and attitude information. The VHF radio can establish a direct line-of-sight shortwave communication link between the aircraft platform and the ground station for transmitting message information. The communication link management unit receives interface data from the satellite communication equipment, aircraft-to-ground communication equipment, BeiDou navigation equipment, and VHF radio, converts the signal data into IP packets, and forwards them to the display and control subsystem via Ethernet.

[0030] The power supply system includes a transformer rectifier, a display control box, a power distribution box, and power cables, used to provide 28V DC power to various system devices during search and rescue missions. The transformer rectifier transforms and rectifies the power output from the aircraft generator, converting it to 28V DC. The display control box is a control terminal with a display interface, used for functions such as turning the transformer rectifier on and off and displaying its operating status. The power distribution box expands the single-channel DC power output from the transformer rectifier into five outputs, each of which can be individually controlled. There are three power distribution boxes, located at the front, middle, and rear of the cabin. The power cables are laid under the cabin floor, with both ends connected to the transformer rectifier and each power distribution box, respectively, to output 28V DC power to the terminals of the power distribution boxes.

[0031] like Figure 2 As shown, the system software of this invention is designed with a top-level solution based on typical application scenarios and general application requirements. It primarily focuses on search and rescue of ships and personnel at sea and oil spill monitoring, while also considering search and rescue of aircraft crashes in high-altitude areas, situation awareness and rescue guidance during floods, and situation awareness and rescue guidance during earthquakes. Furthermore, it designs general display, management, and control functions for common application scenarios. The system software architecture consists of five layers, from top to bottom: application layer (interactive front-end), driver layer (event-driven), service layer (functional modules), transmission protocol layer (device interface), and device layer (hardware peripherals).

[0032] The application layer supports multiple typical application scenarios, including water boundary detection, maritime vessel accidents, personnel search and rescue and oil spill monitoring, flood disaster situation awareness and rescue guidance, earthquake disaster situation awareness and rescue guidance, forest fire disaster situation awareness and rescue guidance, as well as situation awareness and rescue guidance in atypical general scenarios.

[0033] The driver layer receives events from the application layer, responds to user commands, initiates background processing flows, and organizes calls to relevant functional modules in the service layer. It also sends image data and device status to the application layer for display. Figure 2 (In response to upper-layer events, initiate the application management process).

[0034] The service layer includes eight functional modules: task binding, route planning, display management, equipment control, intelligent processing, decision support, database and third-party program management.

[0035] The transmission protocol layer mainly implements hardware device interface protocols, including radar interface protocols and AIS device message protocols.

[0036] The device layer provides the underlying operating and support environment and serves as a platform for system software. It mainly consists of hardware such as task processing computers, integrated data management equipment, shared storage devices, switches, multi-screen displays, gamepads, keyboards, multi-functional radars, photoelectric turrets, AIS, rescue radios, rescue material delivery equipment, interface processors, satellite communication equipment, ground communication equipment, Beidou navigation equipment, ultra-shortwave radios, and communication link management units.

[0037] like Figure 3 As shown, the display and control subsystem is divided into a display management module, a task binding module, a route planning module, an equipment control module, an intelligent processing module, an auxiliary decision-making module, a backend database, and a third-party program management module based on its functions.

[0038] The display management module primarily receives task binding commands from the front-end application, target information such as the task area from the task binding module, route information from the route planning module, equipment status information from the equipment control module, image information output by the payload subsystem, target recognition information from the intelligent processing module, and auxiliary decision-making information from the auxiliary decision-making module. It also retrieves historical data from the back-end database and displays the above information in specific areas of the multi-screen display. The display management module primarily outputs equipment control commands to the equipment control module, route planning commands to the route planning module, and task binding target information to the intelligent processing module.

[0039] The task binding module mainly sends target information such as the task area to the display management module.

[0040] After receiving the route planning command from the display management module, the route planning module generates route information based on the target information such as the area information of the bound task area, and sends it to the display management module.

[0041] The device management module receives the status information of the load device from the load subsystem, sends the status information to the display management module for display, and simultaneously receives the device control commands from the display management module and issues the control information to the load subsystem.

[0042] The intelligent processing module receives target information such as target type and target slice from the display management module, performs internal model training, generates target recognition results, and sends them to the display management module.

[0043] The auxiliary decision-making module sends the generated auxiliary decision-making information to the display management module.

[0044] The backend database stores historical data of the target information for the display management module to access.

[0045] The third-party program management module mainly manages the adaptation and integration of third-party software, including the wide-area search and calculation program for photoelectric turrets, the material delivery location calculation program, and the forest fire prediction program.

[0046] The present invention also provides a search and rescue method for an aviation platform search and rescue system, comprising the following steps:

[0047] Step 1: Activate the display and control subsystem according to the received search and rescue instructions, select the corresponding typical application scenario and select the target type to start the task;

[0048] Step 2: Call the display management module, backend database and task binding module to bind the search and rescue airspace range, target search range, target type and auxiliary information into the backend database;

[0049] Step 3: The route planning module automatically generates the system task route based on the binding information, and after manual confirmation, it forms the route.

[0050] Step 4: The aerial platform flies to the search area according to the mission route, and each search payload completes parameter configuration and enters the corresponding working mode under the control of the display and control subsystem;

[0051] Step 5: The multi-functional radar and / or photoelectric turret acquires target information and transmits it back to the display and control subsystem in real time. The display and control subsystem calls the auxiliary decision-making module and intelligent processing module to perform target recognition and generate recognition result information.

[0052] Step 6: The identification results are sent to the ground station in real time via the communication subsystem for synchronous display, providing a basis for decision-making in search and rescue command.

[0053] Step 7: After the task is completed, save the work log and data, shut down all equipment, and return the aviation platform according to the predetermined route.

[0054] Preferably, AI technologies such as multimodal fusion, diffusion models, and feature pyramids can be used to achieve intelligent search for ships / personnel, precise delivery of supplies, and automatic detection of water boundaries. Small target search strategies can be optimized, and combined with artificial intelligence processing results and expert experience and knowledge, to form an intelligent extraction method for decision support, thereby achieving rapid and accurate target positioning.

[0055] Specifically, for typical maritime search and rescue application scenarios, the following steps are included:

[0056] Step 1, Task Initiation: After receiving the maritime search and rescue instruction, start the display and control subsystem, call the display management module, select the typical application scenario of maritime search and rescue, select the target type as "ship" or "personnel", and click the "Task Initiation" button to start the task;

[0057] Step 2, Task Information Binding: The display and control subsystem calls the display management module, backend database, and task binding module to bind the maritime search and rescue project task information, including the search and rescue airspace range, vessel search range, personnel search range, vessel type, vessel number, AIS navigation mark, material drop point location, etc. The bound maritime search and rescue project task information is automatically stored in the backend database.

[0058] Step 3, Mission Route Generation: Based on the route design command of the display and control subsystem, the route planning module automatically generates a search and rescue route according to the loaded search and rescue airspace range and ship / personnel search range information. After manual confirmation, it becomes the system mission route.

[0059] Step 4: Start the search: The aerial platform search and rescue system takes off according to the system mission route and flies to the ship / personnel search area. Each device of the search and rescue system performs a self-test. Under the control of the display and control subsystem, each search payload completes parameter configuration, sets the multi-function radar to enable WAS working mode, sets the electro-optical pod to enable screen display, and sets the AIS and life-saving radio to enable ship signal receiving mode.

[0060] Step 5: Detecting Ship Targets: After the multi-function radar detects a ship, it displays the target information in the display and control subsystem, including bearing, distance, heading, and speed, to enable continuous tracking of the selected target.

[0061] Step 6: Track and identify the target: The display and control subsystem calls the display management module and the route planning module to automatically / manually generate a ship identification flight route. The aviation platform is dispatched to fly according to the identified flight route. The display and control subsystem performs target identification on the visible light and infrared video and images received from the photoelectric turret. It calls the auxiliary decision-making module to generate target information such as target type information and target confidence level. After the target is confirmed, a material throwing route is generated. Rescue materials are thrown according to the throwing point prompts on the route. After the current target identification and material throwing are completed, this step is repeated to identify the next target.

[0062] Step 7: After identifying the currently discovered ships and other targets, if no target ship requiring rescue is found, the dispatch aviation platform returns to the search flight path, and the search and rescue system continues to repeat steps 5 and 6 to carry out target search until the entire search area is completed.

[0063] Step 8: Real-time information transmission. The identification information of the searched targets such as ships / personnel is transmitted to the ground station in real time through the communication subsystem for synchronous display, providing a basis for decision-making in search and rescue command.

[0064] Step 9: Complete the search and rescue operation. After the mission is completed, the search and rescue system saves the work log and data, all equipment is shut down, and the aviation platform returns along the predetermined route.

[0065] Specifically, for typical oil spill scenarios on water surfaces, the following steps are included:

[0066] Step 1: Task Initiation. After receiving the oil spill search and rescue instruction, start the display and control subsystem, call the display management module, select the typical application scenario for oil spill search and rescue, select "oil spill" as the target type, and click the "Task Start" button to start the task.

[0067] Step 2: Task information binding. The display and control subsystem calls the display management module, backend database, and task binding module to bind the task information of the oil spill search and rescue project, including the search and rescue airspace range and the oil spill range. The bound task information is automatically stored in the backend database.

[0068] Step 3: Mission route generation. According to the route design command of the display and control subsystem, the route planning module automatically generates radar search and rescue route and photoelectric search route based on the loaded search and rescue airspace range and oil spill range information. After manual confirmation, these routes are used as the system mission routes.

[0069] Step 4: Start the search: The aerial platform takes off according to the system mission route and flies to the oil spill search area. All equipment of the search and rescue system performs self-checks. Under the control of the display and control subsystem, each search payload completes parameter configuration, sets the multi-functional radar to start SAR working mode, and sets the photoelectric turret to start screen display.

[0070] Step 5, Oil Spill Identification: After the aviation platform enters the oil spill area, the multi-functional radar and photoelectric turret of the equipment subsystem will send radar images, visible light video and infrared video and other information to the display and control subsystem in real time. The display and control subsystem calls the display management module, equipment management module, auxiliary decision module and intelligent processing module to perform real-time oil spill monitoring and identification and generate oil spill monitoring result information.

[0071] Step 6: Real-time Information Transmission: Once the oil spill identification information on the water surface is completed, it is transmitted to the ground station in real time via the communication subsystem for synchronous display, providing decision-making basis for search and rescue command.

[0072] Step 7: Complete the search and rescue operation. After the mission is completed, the search and rescue system saves the work log and data, all equipment is shut down, and the aviation platform returns along the predetermined route.

[0073] Specifically, for typical application scenarios involving floods and earthquakes, the following steps are included:

[0074] Step 1, Task Initiation: Upon receiving the flood / earthquake search and rescue instruction, activate the display and control subsystem, call the display management module, select the typical application scenario for flood / earthquake search and rescue, select the target type as "water boundary" or "personnel", and click the "Task Initiation" button to start the task;

[0075] Step 2, Task Information Binding: The display and control subsystem calls the display management module, backend database, and task binding module to bind the flood / earthquake search and rescue project task information, including the search and rescue airspace range, water body boundary range, personnel search range, etc. The bound project task information is automatically stored in the backend database.

[0076] Step 3, Mission Route Generation: According to the route design command of the display and control subsystem, the route planning module generates water boundary routes and personnel search routes based on the loaded search and rescue airspace range, water body boundary range, and personnel search range information. After manual confirmation, these routes are used as the system mission routes.

[0077] Step 4: Start the search: The aviation platform takes off and flies to the search area according to the system mission route. All equipment of the search and rescue system is powered on and performs self-checks. Under the control of the display and control subsystem, each search payload completes parameter configuration, sets the multi-functional radar to start SAR working mode, and sets the photoelectric turret to start screen display.

[0078] Step 5, Water Boundary Identification: The aerial platform first executes the water boundary search route. The multi-functional radar and photoelectric turret of the equipment subsystem send radar images, visible light video and infrared video and other information to the display and control subsystem in real time. The display and control subsystem calls the display management module, equipment management module, auxiliary decision module and intelligent processing module to perform water boundary monitoring and identification in real time and generate water boundary monitoring result information.

[0079] Step 6, Personnel Identification: The aviation platform performs personnel search routes. The multi-functional radar and photoelectric turret of the equipment subsystem send radar images, visible light video and infrared video and other information to the display and control subsystem in real time. The display and control subsystem calls the display management module, equipment management module, auxiliary decision and intelligent processing module to identify the personnel to be rescued in real time and generate personnel monitoring result information.

[0080] Step 7: Real-time information transmission: The completed water body boundary and personnel identification information are transmitted to the ground station in real time through the communication subsystem for synchronous display, providing decision-making basis for search and rescue command;

[0081] Step 8: Complete the search and rescue operation. After the mission is completed, the search and rescue system saves the work log and data, all equipment is shut down, and the aviation platform returns along the predetermined route.
