Description

Technical Field

[0001] The present invention relates to the field of civil aviation airborne equipment, and in particular to an interconnected airborne mounted EFB device. Background Art

[0002] Since the 1990s, electronic flight bags (EFBs) have been introduced into aircraft cockpits to provide pilots with electronic charts, flight manuals and other tools.

[0003] EFB equipment is divided into portable EFB equipment and installed EFB equipment.

[0004] Nowadays, portable EFB devices are widely used by major airlines. They are mainly in the form of independent tablet computers, which are carried and kept by flight crews. Most existing aircrafts do not have a communication interface between the core avionics system and the portable EFB devices during the design phase. The portable EFB devices cannot obtain data from the aircraft's core avionics system, nor can they send data to the avionics system.

[0005] As an aircraft onboard display unit, mounted EFB equipment is only available in a few new aircraft models. Moreover, compared with the rapid development of touch-screen devices such as mobile phones, tablets, and car displays, the hardware performance and functions of the mounted EFB equipment of existing models have been completely outdated. Some models of mounted EFB equipment still rely on button operation and can only use factory-installed applications, without the possibility of functional expansion.

[0006] Moreover, there is no data communication interface between the installed EFB devices in the cockpit of existing large passenger aircraft and the portable EFB devices, and the portable EFB devices cannot be used in coordination with other devices in the cockpit. For example, the chart software in the portable EFB device needs to obtain the real-time latitude and longitude of the aircraft, but it cannot obtain it due to the lack of communication interface; the portable EFB device needs to project the display content onto the onboard display, but it also lacks a data transmission channel.

[0007] Secondly, the lack of speakers, microphones and cameras for network audio and video calls in the cockpits of existing large passenger aircraft means that the crew can only use radio voice calls or expensive satellite calls when communicating with airline dispatchers and maintenance personnel. At the same time, the lack of the above equipment also limits the functional development of aircraft avionics equipment, such as facial recognition identity authentication and voice input functions, which cannot be realized in the hardware environment of the existing cockpit. Summary of the invention

[0008] In order to solve the above-mentioned problems in the prior art, the present invention provides an interconnected airborne mounted EFB device, which provides a cockpit with rich audio and video service functions; and enables the aircraft cockpit mounted avionics equipment and the crew's portable devices to be interconnected and used in coordination, which greatly improves the pilot's operating experience of using multiple devices in the cockpit and reduces the additional workload generated when the crew switches between multiple devices; and effectively reduces the total weight and volume of the aircraft cockpit avionics equipment, which has low noise, good heat dissipation performance, low equipment failure rate, and more stable operation, effectively improving the automation and intelligence level of the aircraft cockpit and improving the crew's work efficiency.

[0044] The display module 1 mainly includes a display module panel 5 , a liquid crystal touch screen 6 , a speaker 7 , an antenna module 8 , a camera 9 , and a microphone 10 .

[0045] The display module panel 5 is made of aluminum alloy, which can enhance the electromagnetic shielding capability of the device.

[0046] The liquid crystal touch screen 6 is a capacitive screen, which is manufactured using a full lamination process, which can significantly reduce light reflection, reduce light loss, thereby increasing brightness, and also reduce the probability of air and dust entering.

[0047] The speaker 7, camera 9, and microphone 10 are all waterproof models. The display module panel 5 is formed by CNC processing. The speaker 7, camera 9, and microphone 10 are pressed in from the opening at the rear of the display module panel 5 and sealed by dispensing glue. This method ensures the overall waterproof performance of the device, meets the waterproof characteristics requirements of airborne equipment, and ensures the structural strength of the panel. The speaker 7 uses a waterproof speaker to enhance the waterproof performance of the device; the camera 9 uses a waterproof camera module, which can provide high-definition video recording, photo shooting, and face recognition functions; the microphone 10 uses a waterproof microphone to increase the waterproof performance of the device.

[0048] The antenna module 8 includes an antenna 15 and a protective cover 16. The antenna module 8 is located at the upper right of the display module 1. A T-slot 14 is opened on the upper side of the display module panel 5. The T-slot 14 has openings on the front and side of the display module panel 5. The antenna 15 is fixed in the T-slot 14 opened on the side of the display module panel 5 by screws. The T-slot is sealed with an acrylic protective cover 16 to increase the waterproof performance of the device but will not affect the signal strength of the antenna. The T-slot 14 has openings on the front and side of the device, so that the Wi-Fi signal emitted by the antenna 15 can be emitted from the front and side of the device, increasing the available emission area and coverage angle of the antenna 15; and the bottom and side of the T-slot 14 still retain the metal structure, ensuring the electromagnetic shielding performance of the device and meeting the electromagnetic shielding performance requirements of airborne equipment.

[0049] The antenna 15 adopts an integrated chip of Wi-Fi and Bluetooth, and integrates a Bluetooth 4.1 chip through a Wi-Fi module, thereby providing Bluetooth signal access while providing a Wi-Fi hotspot.

The heat of the mainboard components is exported through a flexible thermal pad inside the device, and the heat is dissipated through external heat dissipation fins to achieve passive heat dissipation. This method eliminates the need for an additional cooling fan for the device, reduces the number of active parts, increases the seismic resistance of the device, extends the overall service life of the device, and reduces the overall weight of the device.

[0053] The present invention integrates a speaker, a microphone and a camera, and can provide a variety of audio and video service functions for the cockpit, including but not limited to video calls, face recognition, and voice input functions. The integration of this device will effectively improve the automation and intelligence of the aircraft cockpit and improve the work efficiency of the crew.

[0054] At the same time, since the equipment is a highly integrated integrated device, its volume and weight are much smaller than the total volume and weight of separately added speakers, microphones, and camera accessories, effectively reducing the total weight and volume of the aircraft cockpit avionics equipment.

[0055] The device of the present invention adopts a low-power and high-performance CPU chip, and cooperates with an integrally formed backplane for passive heat dissipation to reduce the internal temperature of the device during operation. Compared with traditional fan heat dissipation, it has fewer moving parts, less noise, better heat dissipation performance, lower equipment failure rate, and more stable operation.

[0056] The device uses a Wi-Fi and Bluetooth integrated chip to provide wireless network and Bluetooth interface for portable EFB devices and wearable devices in the cockpit, so that the aircraft cockpit-mounted avionics equipment and the crew's portable devices can be interconnected and used in coordination, greatly improving the pilot's operating experience in using multiple devices in the cockpit and reducing the additional workload generated by the crew when switching between multiple devices.

[0057] The device uses the OpenHarmony operating system, which allows host manufacturers and airlines to expand the installation of flight and maintenance-related application software, making it more flexible to use and maintain and more powerful.
