Description

Technical Field

[0001] The invention relates to the field of aviation airborne information systems, in particular to an airborne information system of a large fixed-wing aircraft, and in particular to an interconnected electronic flight bag system and an interconnection method thereof. Background Art

[0002] Traditional flight bags are usually a document bag that pilots carry to the cockpit. These paper reference materials include aircraft operating manuals, flight crew operating manuals, and navigation charts. With the automation of electronic information, electronic flight bags (EFBs) have emerged. Electronic flight bags help flight crews use less paper and perform flight management tasks more easily and effectively. Electronic flight bags are divided into portable electronic flight bags (PEFBs) and mounted electronic flight bags (MEFBs). PEFBs have been put into operation on routes for many years. They can replace traditional flight bags and display a variety of aviation information data, greatly reducing the burden on crew members. However, due to the low safety certification and the inability to interact with the aircraft's own airborne system, it is impossible to obtain real-time parameters during the flight of the aircraft, which has major defects. With the key breakthroughs in the construction of "smart civil aviation", it is possible to display aircraft operation support information in the cockpit and integrate corresponding digital manuals, electronic charts, video monitoring and performance calculation software. In order to improve the safety level of PEFB and expand its onboard functions, MEFB was born. As one of the important carriers for the construction of "smart civil aviation" of airlines, MEFB has become an important part of the digital transformation and smart operation of airlines, laying the foundation for the subsequent expansion of interconnected flight management systems.

[0003] However, due to the short installation time of MEFB, the electronic flight bag has the following defects: a) The MEFB had not been in operation for a long time, which led to low pilot acceptance; b) There is a data island between PEFB and MEFB, and the data of PEFB does not contain real-time data of aircraft parameters; c) MEFB has low daily utilization; d) Although MEFB can interact with airborne equipment, it is not portable enough and cannot be connected to PEFB, resulting in ineffective communication between MEFB and PEFB and lack of interoperability.

[0004] Therefore, if an interconnected electronic flight bag system and its interconnection method can be developed that can cultivate user usage habits to adapt to the operation of new aircraft models, the interconnected electronic flight bag system can realize multi-screen collaboration and data synchronization of PEFB and MEFB, and can realize navigation operation functions such as video monitoring, chart display, flight manual management, performance calculation, WEB browser display, etc. The interconnected electronic flight bag system also integrates communication interfaces such as Ethernet, WIFI, Bluetooth, USB, etc., and uses domestic operating systems to host application software to achieve good interoperability and real-time performance, which will have great market prospects.

The plug-in wireless connection module receives the multi-screen video signal and main control command from the multi-screen collaboration software, and directly triggers the automatic screen-off function of the portable electronic flight bag.

[0064] The interconnection process of multi-screen collaboration software and multi-screen collaboration plug-in is as follows: The user issues the main control command on the multi-screen collaboration software through the integrated user interface to control the issuance of multi-screen video signals, and then controls the multi-screen wireless connection module to send multi-screen video signals through the multi-screen function call module, which is transmitted to the plug-in wireless connection module via wireless WIFI. After the multi-screen collaboration plug-in receives the WIFI signal, it immediately synchronizes it to the plug-in video signal module through the plug-in function call, triggers the plug-in control command, and starts the automatic screen off.

[0065] like Fig.10 As shown, this is a schematic diagram of the architecture of the ground server of the interconnected electronic flight bag system in the second embodiment.

[0066] The ground server includes a chart update module and a manual update module, which reside in the server operating system. The chart update module and the manual update module are wirelessly interconnected and interacted with the airborne equipment through the server's operating system and the server's WIFI interface.

[0067] WIFI, Bluetooth and Ethernet provide MEFB with external wired and wireless network connections to support remote updates of ground servers and multi-screen collaboration functions.

[0068] like Figure 6 and Figure 7 As shown, the interconnected electronic flight bag system of the second embodiment works according to the following process: The mounted electronic flight bag of the present invention uses Ethernet to interconnect and interact with the aircraft body using the information system data relay platform and the aircraft information system; when flying in the air, the mounted electronic flight bag uses WIFI to interconnect and interact with the multi-screen collaborative plug-in in the portable device using the mounted electronic flight bag multi-screen collaborative software; when parked on the ground, the mounted electronic flight bag obtains the latest manual information and navigation information from the ground server via WIFI; the mounted electronic flight bag interconnects and interacts with the external USB storage device via the USB port through the domestic operating system, realizing real-time data sharing with the aircraft system, ensuring that the pilot can obtain the latest key information such as flight intelligence and weather information at any time, and enhancing the crew's comprehensive perception of the flight status. The detailed process can be as follows: Step 1: Power on and start the integrated user interface; Step 2: Start the installed EFB integrated user interface and connect to Ethernet; Step 3: The aircraft information system automatically detects the data channel. If it is normal, it is determined that the communication with the aircraft information system is normal, and then step 4 is executed. If it is not normal, step 7 is executed; Step 4: The installed electronic flight bag automatically identifies whether there is an aircraft wheel-borne signal. If there is no wheel-borne signal, execute step 5. If there is a wheel-borne signal, execute step 6. Step 5: Start the integrated user interface of the mounted electronic flight bag to connect to the WiFi hotspot of the portable device, and open the mounted electronic flight bag and multi-screen collaboration software for multi-screen collaborative operation; Step 6: Start the integrated user interface of the installed electronic flight bag, connect to the designated WIFI to access the ground server, read and update the manual information and navigation information stored in the installed electronic flight bag; Step 7: Determine whether the automatic repair is successful; if successful, return to step 1; if unsuccessful, proceed to step 8; Step 8: Prompt for maintenance; Step 9: End.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
