Description

Airborne network server for cockpit and passenger cabin

Technical Field

The utility model relates to the technical field of aircraft cabins/cabins, in particular to an onboard network server of a cockpit and a cabin.

Background

From the future view of the aircraft cockpit/cabin, the cockpit/cabin will be further developed in data applications, cabin entertainment and on-board internet. The implementation of the conventional network server technology at present comprises the following two schemes:

the first scheme is as follows: a system consisting of a network server, a WiFi distribution device and a multimode cellular communication device is employed. The traditional network server is mainly an X86 architecture, can support multiple paths of 2.5 inch hard disks, and is used as an application server and a switch. The WiFi distribution device acts as a stand-alone Access Point (AP) for cabin interior coverage. Multimode cellular communication devices are primarily used for communication with the background while the aircraft is on the ground.

The disadvantages of this solution are: the number of line replaceable units (Line Replaceable Unit, LRU) is large, the scheme of installation and modification is complex, and the cost is high. Because the network server adopts the X86 architecture, the power consumption is higher, and the power consumption of the whole system is difficult to control to a lower level, namely the higher fuel cost can be consumed.

The second scheme is as follows: a network server integrating cellular communication equipment is adopted, and a WiFi distribution equipment is added to form a system. Among them, the network server integrating cellular communication is mostly single-mode at present.

The disadvantages of this solution are: although the network server reduces the number of LRU (least recently used) of the system and solves the problem of complex installation and modification by integrating the cellular communication modules, the network server is limited by the performance requirement of the network server, generally has only single-mode cellular communication capability and has poor adaptability on international airlines.

In addition, while in actual commercial operation, the two solutions described above have the following drawbacks:

since satellite communication is closed after the aircraft lands, the aircraft can only access the public network through cellular communication to connect data. There are certain advantages to the need for aircraft ground access to the public network, but there are also many problems, such as low security, low data rate, high cost, etc. In addition, from the aspect of communication, mobile cellular communication systems are more all over the world, and networks of different operators cannot be used commonly (SIM cards on hardware can be registered after replacement), so that extra means are needed to ensure that each airplane can access the background after landing.

On the other hand, there is also the problem of the WiFi of the ground maintenance being shared with the WiFi of the cabin. Both the current ground maintenance and data synchronization are performed by means of the cabin WiFi equipment channel. However, the cabin WiFi device is not always opened, and the cabin WiFi device can be started after the cabin door is closed by an operator, but a part of the avionics follows that the WiFi device can be opened after the aircraft flying height is greater than 3048 meters (i.e. 10000 feet), so that the ground device cannot communicate by using the cabin WiFi device. Also, since cabin WiFi is directly facing the end user, this poses a security risk to ground maintenance management.

The problem that each aircraft brought by the public network cellular network can be connected into the background after landing and the problem that WiFi for ground maintenance is shared with WiFi in a cabin is a technical problem which is solved first.
