Description

Technical Field

[0001] This utility model belongs to the category of electronic technology and is applied to the field of aviation electronic technology. Specifically, it relates to a floating trajectory data recording and emergency positioning and launching device. Background Technology

[0002] Emergency locator transmitters are essential emergency equipment for aircraft. They have buoyancy and crashworthiness capabilities and can be automatically or manually triggered when an aircraft is in distress. By transmitting radio distress signals and location information, they help search and rescue personnel determine the location of the accident and quickly carry out rescue operations.

[0003] Currently, most helicopter platforms' emergency locator transmitters send distress signals via the Global System for Satellite Search and Rescue (GSDS). After being relayed, user terminals calculate the location of the distressed target, which is then notified to search and rescue departments in the distressed area via international communication networks. A few emergency locator transmitters utilize the global location reporting function of the BeiDou Navigation Satellite System for search and rescue. Regardless of the method, once a helicopter crashes at sea and its "black box" sinks to the bottom, the emergency locator transmitter becomes the only equipment capable of guiding search and rescue forces to the crash site. Emergency locator transmitters with "black box" functionality become the sole basis for flight accident investigation and analysis. Malaysia Airlines MH370 has been missing for ten years and remains unaccounted for. The accident investigation organization analyzed massive amounts of data, studied the missing flight path, and searched for the crash site. Therefore, trajectory data is of great significance for accident investigation and analysis. Utility Model Content

[0004] Purpose of the utility model: To provide a floating trajectory data recording and emergency positioning transmitter, which helps to track and locate helicopter crash sites, guide rescue forces in search and rescue operations, and assist in the investigation and analysis of accidents.

The power and data management module 2 is connected to the data recording component 3, the radio beacon module 6, the Beidou beacon module 7, the upper strobe light 4, and the lower strobe light 5.

[0008] The BeiDou beacon module 7, controlled by the power supply and data management module 2, enables BeiDou positioning and global short message services.

[0009] The radio beacon module 6 is controlled by the power and data management module 2, enabling periodic transmission and reception of radio beacon and spread spectrum signals. It can communicate with VHF search and rescue radios to guide maritime search and rescue forces in search and rescue operations.

[0010] After leaving the aircraft, it can float on the sea surface and be located in real time through the Beidou beacon module 7, forming a trajectory data stored in a data recording component with crashworthiness protection.

[0011] Furthermore, it also includes a sealing ring 11, which is located around the perimeter of the protective outer cover 12 in contact with the protective base plate 13, for sealing and waterproofing, so as to prevent water vapor from entering when floating on the sea surface.

[0012] Furthermore, the protective cover 12 and the protective base plate 13 are used to fix all modules and structural components, and the two are connected by screws.

[0013] Furthermore, the antenna 8 is connected to the radio beacon module 6 and the Beidou beacon module 7 respectively, for transmitting and receiving radio signals.

[0015] Furthermore, the power and data management module 2 controls the opening or closing of the battery pack 1 switch. After the floating trajectory data recording and emergency positioning transmitter is launched, the battery pack 1 switches on to supply power to the power and data management module 2, data recording component 3, upper strobe light 4, lower strobe light 5, radio beacon module 6, and Beidou beacon module 7.

It controls the power supply management of the external power supply and the battery pack 1, receives Beidou positioning information in real time to form floating trajectory data, and sends it to the data recording component 3 through the internal bus. At the same time, it controls the radio beacon module 6 and Beidou beacon module 7 to periodically send information and the operating frequency of upper strobe light 4 and lower strobe light 5.

[0024] like Figure 2As shown, the data recording component 3 is connected to the power supply and data management module 2, and consists of a protective layer and a data storage module. The protective layer provides protection against mechanical and thermal stress damage and has crash-resistant survival capability. The data storage module is used to store the floating trajectory data in real time after the aircraft leaves the ground for accident investigation and analysis.

[0029] like Figure 1 , Figure 2 As shown, the protective foam comprises two parts: an upper protective foam 9 and a lower protective foam 10. The upper protective foam 9 is used for fixing and installing the antennas of the radio beacon module 6 and the Beidou beacon module 7, while the lower protective foam 10 is used for fixing the battery pack 1, the power and data management module 2, the data recording component 3, the radio beacon module 6, the Beidou beacon module 7, and the antenna 8. All of these components are installed inside the cavity of the protective foam and are integrally molded using a low-density, lightweight foam material with good energy absorption.

[0030] like Figure 1 As shown, the sealing ring 11 is located around the contact area between the protective outer cover 12 and the protective base plate 13, and is mainly used for sealing and waterproofing design to prevent water vapor from entering when floating on the sea surface.
