Abstract
Description
Technical Field
[0001] The present invention relates to an aviation auxiliary device, in particular to an electronic flight system. Background Art
[0002] An electronic flight bag is an aviation auxiliary device used to provide materials such as flight manuals to pilots in the cockpit to replace traditional paper materials.
[0003] Currently, the electronic flight bag is mainly implemented by installing relevant software in a tablet device. This method requires the pilot to manually search and download required charts and other materials before each flight, which is rather inconvenient; during the flight, in order to ensure sufficient power for the electronic flight bag, it is usually connected to the on-board power supply, but the risk of charging lithium batteries at high altitudes is relatively high; at the same time, relevant charts and other materials are stored in the tablet device, and it is difficult to keep the files confidential. Summary of the Invention
[0004] In order to solve the above technical problems, the present invention provides an electronic flight bag system to overcome the deficiencies of the prior art.
[0005] The technical solution adopted by the present invention is: an electronic flight bag system for the aerospace field, having a host device, a battery, and a data memory card; the host device is installed in the cockpit of the aircraft and does not need to be connected to the aircraft power supply; the battery provides an independent power supply for the host device and can be detached from the host device for independent charging; the data memory card pre-stores information related to the current flight.
[0006] Preferably, it includes a battery charging station managed by an airline or an airport for uniformly managing and charging the battery, so that the pilot only needs to pick up the charged battery before takeoff for use; the battery charging station can predict the power demand according to the flight plan data and remind the pilot to carry the required number of batteries.
[0007] Preferably, it includes a battery charging station managed by an airline or an airport for uniformly managing and charging the battery; the battery charging station can predict the power demand according to the flight plan data and remind the pilot to carry the required number of batteries.
[0008] Preferably, the data memory card has a hardware-level encryption function to protect the sensitive information stored on it from unauthorized access; the data memory card can update the materials stored in the host device.
[0009] Preferably, after the data memory card is inserted into the host device, it can automatically read and display information such as charts and air routes without the pilot having to manually input queries.
[0010] Preferably, the battery adopts a hierarchical power supply architecture, including a main power supply layer and an emergency power supply layer. An intelligent isolation circuit is arranged between the two power supply layers, and automatically switches to the emergency power supply layer when the voltage of the main power supply layer is lower than the threshold.
[0011] Preferably, the host device supports voice recognition, touch screen, and button operations; the voice recognition supports recognizing cockpit alarms by sound and automatically displaying checklists.
[0012] Preferably, the host device can be directly installed on the existing portable electronic flight bag bracket or directly placed in the cockpit.
[0013] Preferably, the host device can manually query information when no data memory card is inserted.
[0014] By introducing a data memory card, the present invention preferably solves the cumbersome steps that the pilot needs to manually search for information each time, and also preferably enhances the degree of anti-leakage of relevant data. At the same time, it can also ensure that the information in the host device is kept up-to-date, eliminating the need for manual information update steps; by introducing a detachable battery, the risk of in-air charging is eliminated; at the same time, only the battery and the data memory card need to be carried when getting on and off the plane, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 is a schematic diagram of the steps taken by the pilot before boarding the plane.
[0016] Figure 2 is a schematic diagram of the startup process of the electronic flight bag host device. DETAILED DESCRIPTION OF THE INVENTION
[0017] The present invention will be further described below in conjunction with the drawings and embodiments.
[0018] Please refer to Figure 1 and Figure 2 , where Figure 1 is a schematic diagram of the steps taken by the pilot before boarding the plane according to the present invention; Figure 2 is a schematic diagram of the startup process of the electronic flight bag host device according to the present invention.
[0019] As Figure 1 described, in use, the pilot only needs to receive the battery and the data memory card before boarding the plane and insert them into the host device after entering the cockpit, and the host device can automatically display the relevant documents required for the current flight.
[0020] As Figure 2 described, when the host device starts up, it will automatically determine whether there is a data memory card. If not, the pilot can manually query the data. If there is, it will first check whether there is information that needs to be updated, and finally display the information required for the current flight.
[0021] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
