[0002] When an aircraft is in distress, various situations may arise due to human factors, environmental factors, etc., which may prevent rescuers from immediately locating the incident site and carrying out rescue operations, threatening the lives of pilots and passengers.

[0003] To address issues such as untimely rescue, inaccurate positioning, and unclear targets when aircraft are in distress, there is an urgent need to develop an airborne device that integrates drop-off and positioning functions. Utility Model Content

[0004] Purpose of the utility model: To provide an emergency rescue positioning system that integrates throwing and positioning functions, thereby improving search and rescue capabilities and reducing rescue time.

[0005] Technical solution:

[0006] An emergency rescue positioning system integrating throwing and positioning functions includes: a control converter, a positioning transceiver, an overload start device, a water immersion start device, and a control box, wherein...

[0007] The control converter and the overload starter are interconnected via a single bus interface, enabling the transmission of overload data to the control converter. They are also interconnected via a single discrete signal interface, allowing the output of an overload trigger signal to the control converter. Furthermore, the control converter and the overload starter are interconnected via a single power interface, enabling the control converter to supply power to the overload starter. The control converter and the immersion starter are interconnected via a single discrete signal interface, enabling the output of an immersion trigger signal to the control converter. Finally, the control converter and the positioning transceiver are interconnected via a single Ethernet bus interface, enabling the output of flight data, audio data, and overload data to the positioning transceiver for recording. The system is interconnected via one bus interface to output the status information of the positioning transceiver; the control converter is interconnected with the positioning transceiver via one discrete signal to output the start positioning signal to the positioning transceiver; the control converter is interconnected with the positioning transceiver via one discrete signal to output the release signal to the positioning transceiver; the control converter is interconnected with the positioning transceiver via one power interface to supply power to the positioning transceiver; the control converter is interconnected with the field detection equipment via one Ethernet bus to enable data download and system maintenance functions; and the control converter is interconnected with the control box via three discrete signals to enable manual start positioning, manual release, and power switch functions.

[0008] Furthermore, during ground maintenance, the control converter and the field testing equipment are interconnected via a single Ethernet bus to enable data download and system maintenance-related functions.

[0009] Furthermore, the positioning transceiver includes a data and power management module, a data recording component, a BeiDou beacon module, a radio beacon module, a battery pack, a separation device, and a strobe light. The positioning transceiver receives data via an Ethernet bus and writes the data into the data recording component. When a manual activation positioning signal is received, the pilot manually triggers the life-saving beacon launch function. When a jettison signal is received, the transceiver detaches from the aircraft, connects the battery pack to power the BeiDou beacon module, the radio beacon module, and the strobe light, and continuously sends positioning signals to guide search and rescue forces to the crash site to conduct search and rescue operations.

[0010] Furthermore, the control box includes a light guide plate, a chassis, a toggle switch, status lights, and connectors. The control box toggles the manual start positioning switch to send a positioning signal to the control converter; the control box toggles the manual release switch to send a release signal to the control converter; and the control converter is powered by a power switch.

[0011] Furthermore, the immersion start device includes a base, a bottom plate, a dust cover, a connector, and a water sensor. When the immersion start device is fully immersed in seawater or river water, its resistance is approximately 1Ω to 101Ω, which is less than 1016Ω in air. The change in its resistance is used to determine whether the device has entered the water, and it is used to locate the water entry and release separation of the transceiver equipment.

[0012] Furthermore, the overload start-up device includes a simulated MEMS accelerometer, a 422 communication interface, a solid-state relay, and a microprocessor and related peripheral circuits to realize the functions of acquiring, judging, and controlling the output of overload trigger signals.

[0013] Beneficial effects:

[0014] In the event of an aircraft accident, it can automatically or manually deploy a positioning and transceiver. This transceiver has a certain degree of crashworthiness and buoyancy; it can be deployed directly to the ground at low altitudes or float at sea, transmitting BeiDou positioning signals, beacon signals, and flashing position signals to guide rescue helicopters for rapid location and search and rescue operations. It also has the ability to simultaneously record flight parameter data and three-axis accelerometer data. This significantly improves search and rescue capabilities and is crucial for determining the crash site and analyzing the cause of the malfunction. Attached Figure Description

[0024] like Figure 1 The diagram shows the structural block diagram of an emergency rescue positioning system with integrated throwing and positioning functions. The emergency rescue positioning system consists of a control converter, a positioning transceiver (including a separation device), an overload start device, a water immersion start device, and a control box.

[0025] The emergency rescue positioning system is centered around a control converter. Externally, it can interface with the onboard flight parameter system, integrated display system, and other systems to perform data acquisition and interaction, maintenance self-checks, and fault reporting. Similarly, during ground maintenance, it can connect with ground maintenance equipment to perform data download, restoration, equipment checks, and maintenance self-checks. Internally, it receives overload data and overload trigger signals from the overload start device, immersion signals from the immersion start device, and manual start positioning signals and manual release signals from the control box. It then controls the output of release separation signals and start positioning signals to the positioning transceiver equipment.

[0026] The positioning transceiver is a terminal, and all recorded data is stored in its recording unit. When the positioning transceiver receives the release separation signal from the control converter, it detaches from the main body and transmits beacon signals, spread spectrum / standby response signals, Beidou signals, and flashing position signals to guide search and rescue forces to the crash site to carry out search and rescue operations.

[0027] The overload activation device is used to sense the helicopter overload signal, and after voting on the overload signal, it outputs an overload trigger signal to the control converter.

[0028] The immersion activation device is used to sense immersion signals. After the helicopter enters the water, it outputs an immersion trigger signal to the control converter.

[0029] The control box inputs a manual start positioning signal to the control converter. The control converter determines the manual start positioning signal and outputs it to the positioning transceiver, continuously sending positioning signals to guide search and rescue forces to the crash site. When the helicopter is in distress, it can be manually jettisoned. The control converter determines the manual jettison signal, causing the positioning transceiver to jettison, guiding search and rescue personnel to the vicinity of the crash site for rescue work.

[0030] The five components of the system work asynchronously and in a coordinated manner to jointly fulfill the system's functions and mission.

[0031] like Figure 2 The diagram shows the principle block diagram of the positioning transceiver device. The device consists of a data and power management module, a data recording component (including a data storage module), a BeiDou beacon module, a radio beacon module, a battery pack, a separation device, and a strobe light. The device receives data via an Ethernet bus and writes it to the data recording component. Upon receiving a positioning activation signal, it connects the battery pack to power the BeiDou beacon module, radio beacon module, and strobe light, continuously transmitting positioning signals to guide search and rescue forces to the crash site.

[0032] External interconnection diagram of an emergency rescue positioning system integrating throwing and positioning functions is shown below. Figure 3 As shown, the machine provides a 28VDC power supply to power the product; it can provide corresponding bus signal displays or other systems for control interaction and data transmission from the flight parameter system; it can receive, store, and play back audio data according to user needs; and it has an Ethernet maintenance interface for connecting to an external field monitoring computer for product maintenance. The control converter interconnects with external and internal systems, responsible for internal and external interaction, and together they complete the emergency rescue and positioning system function.

[0033] like Figure 4 The diagram shows the internal interfaces and interconnections of an emergency rescue positioning system that integrates throwing and positioning functions. Based on the system composition, capabilities, and interface requirements, the components of the emergency rescue positioning system should have the following internal interfaces, as well as the ability to communicate with each other through these interfaces:

[0034] a) The control converter and the overload starter are interconnected through a 1-channel bus interface to enable the overload data to be sent to the control converter;

[0035] b) The control converter and the overload starter are interconnected through a discrete signal interface to realize the function of outputting the overload trigger signal to the control converter;

[0036] c) The control converter and the overload starter are interconnected through a power interface to enable the control converter to supply power to the overload starter;

[0037] d) The control converter and the immersion start device are interconnected through a discrete signal interface to realize the function of outputting the immersion trigger signal to the control converter;

[0038] e) The control converter and the positioning transceiver are interconnected through a 1-channel Ethernet bus interface to enable the output of flight data, audio data and overload data to the positioning transceiver for recording.

[0039] f) The control converter is interconnected with the positioning transceiver through a 1-channel bus interface to realize the function of outputting the status information of the positioning transceiver;

[0040] g) The control converter and the positioning transceiver are interconnected through one discrete signal to realize the function of outputting the start positioning signal to the positioning transceiver;

[0041] h) The control converter and the positioning transceiver are interconnected through one discrete signal to realize the function of outputting the throwing signal to the positioning transceiver;

[0042] i) The control converter and the positioning transceiver are interconnected through a power interface to enable the control converter to supply power to the positioning transceiver;

[0043] j) The control converter and the field testing equipment are interconnected via one Ethernet bus to enable data download and system maintenance functions.

[0044] k) The control converter and the control box are interconnected through 3 discrete signals to realize functions related to manual start positioning, manual throwing, and power switch.

[0045] The emergency rescue and positioning system designed in this invention integrates drop-off and positioning functions. When an aircraft is in distress, the positioning transceiver is automatically dropped off, detached from the aircraft, and sends a positioning signal, greatly simplifying the rescue system and reducing the weight of the aircraft.

[0046] The positioning transceiver device designed in this invention, after being deployed, sends BeiDou positioning signals to the ground command aircraft to report its location. Radio beacon signals and spread spectrum / standby response signals can be used to search for the specific location and direction at medium range via a rescue radio, while flashing position indicators display the location at close range. These multiple methods of determining the aircraft crash location can significantly improve positioning accuracy and shorten rescue time.

[0047] The positioning transceiver device designed in this invention includes a data storage unit. After being thrown and retrieved, the data can be restored, which is of great significance for analyzing the cause of the fault.

Specific examples have been used to illustrate the principles and implementation methods of this utility model patent. The descriptions of the above embodiments are only for the purpose of helping to understand the core idea of ​​this utility model patent. It should be noted that for those skilled in the art, several improvements and modifications can be made to the utility model patent without departing from the principles of its creation, and these improvements and modifications also fall within the protection scope of the utility model patent claims.
