Problems solved by technology

Some domestic airlines have trial-installed airborne WIFI systems with only LAN functions and airborne WIFI systems using WIFI+ATG technology and WIFI+maritime satellites, but they are all small-scale installations and trial operations
The main reason why the airborne WIFI system is not popular in China is that the ATG mode has no commercial frequency in China, the Ku satellite mode is expensive, not economical, and it is difficult to recover the investment. The lack of satellites in the sky is not suitable for large-scale deployment. Ka-band satellites are currently in domestic use. Civil aviation has no resources available

Abstract

The present invention relates to an airborne WIFI system architecture. The airborne WIFI system architecture is designed to allow users in an aircraft cabin to access a WIFI network on the aircraft by using a mobile terminal to enjoy services such as audio and video, games, news and internet. The airborne WIFI system architecture comprises an airborne router, an airborne network server, a cabin access point, a WIFI antenna and a 3G / 4G antenna. The airborne router is connected with the 3G / 4G antenna by using a radio frequency cable and can access a 3G / 4G network of a base station of a nearby operator so as to communicate with a ground operation center. The airborne network server is connected with the airborne router by using the Ethernet and is connected with the cabin access point by using the Ethernet. The cabin access point is connected with the WIFI antenna by using the radio frequency cable. A first control switch and two relays are arranged between the airborne router and a power supply system. One relay receives a turn-on signal of an aircraft anti-collision lamp, and the other relay receives a turn-off signal of an aircraft cabin door. A second control switch is arranged between the cabin access point and the power supply system and is used for controlling on and off of power supply of the cabin access point.

Description

technical field [0001] The present invention relates to aircraft design technology, further to an entertainment information system on a civil airliner, and specifically to an airborne WIFI system configuration. Background technique [0002] The competition in the air transportation market is intensifying day by day. Airlines want to establish their own brand image by improving the interior facilities of the cabin and improving the service level on the plane, improve passenger satisfaction, and then establish a competitive advantage. The in-flight entertainment system plays an important role in this respect. play a vital role. [0003] At present, the in-flight entertainment and information network system is mainly based on the traditional in-flight entertainment system (IFE) of the cabin hanging TV and the AVOD display screen installed on the back of the seat. Content update costs are high and the cycle is long. In recent years, with the rapid development of Internet techn...
