Personal Communication System in Aircraft Based on Optical Communication

Abstract

The invention relates to a personal communication system in an aircraft based on optical communication, which includes a communication terminal, an airborne communication device, a communication satellite and a ground base station. The airborne communication equipment is set on the aircraft and is used to communicate with communication terminals and communication satellites, wherein, the airborne communication equipment and the communication terminal perform signal transmission through optical signals; the ground base station and the communication terminal The above-mentioned communication satellite and the ground communication network are used for communication. In the present invention, by performing signal transmission between the airborne communication equipment and the communication terminal by optical signals, the electromagnetic wave frequency of the communication equipment is not close to or superimposed with the electromagnetic wave frequency of aircraft such as airplanes and towers, and the optical signal will not be blocked. It is regarded as the operation signal sent by the tower, so it will not cause misoperation, so as to realize any communication between the air and the ground, and the aircraft is safer.

Description

technical field [0001] The invention relates to a communication system, in particular to a personal communication system in an aircraft based on optical communication. Background technique [0002] According to statistics, there are more than 20 flight accidents caused by the use of mobile phones every year in the world in recent years. Therefore, many airlines in the world stipulate that the use of mobile phones is prohibited during aircraft flight. The plane flies along the prescribed course at high altitude, and the whole flight process must be directed by the ground aviation management personnel. At high altitude, the pilot uses the communication and navigation equipment on the aircraft to communicate with the ground tower while driving the aircraft. The navigation equipment on the plane uses radio waves for direction finding and navigation. After receiving the electromagnetic waves continuously emitted by the ground tower, it can measure the exact position of the plane...

Problems solved by technology

[0003] When the mobile phone is working, it will radiate electromagnetic waves, and the electromagnetic wave frequency used by the mobile phone is similar to or even superimposed with the electromagnetic wave frequency used by the aircraft and the tower. It may be regarded as an operation signal from the tower, causing misoperation.

For example, when the aircraft is descending, the tower requires the aircraft to hover or rise. If there is an aircraft below it, but at this time, if there is an electromagnetic wave signal from a mobile phone, it will affect or superimpose on the aircraft operation signal, making the operation signal received by the control room change. down, a major accident may occur
