A wireless earphone and a communication system inside and outside the cabin

Abstract

The invention discloses a wireless earphone which is convenient to use and can be connected to an aircraft intercom system, and a communication system inside and outside the cabin. The communication system inside and outside the cabin includes an aircraft intercom subsystem, a wireless transceiver and multiple wireless earphones; the aircraft intercom subsystem is connected to the aircraft data port of the wireless transceiver through the aircraft service panel, and is used to transmit the voice signal in the cabin to wireless transceiver, and accept the voice signal outside the cabin transmitted by the wireless transceiver; the wireless transceiver is matched with the aircraft service panel and accepted the control of the aircraft service panel, and is used to carry out the voice signal in the cabin provided by the aircraft internal voice subsystem After processing, it is modulated to a wireless carrier of a predetermined frequency, and is also used to receive and process the voice signal outside the cabin sent by the wireless headset, and then transmit it to the aircraft internal voice subsystem. The invention can facilitate the voice communication of personnel inside and outside the aircraft cabin, and reduce the hidden danger of aircraft safety.

Description

technical field [0001] The invention belongs to the field of civil aviation, and in particular relates to a wireless earphone connected to a voice subsystem in a cabin and a communication system inside and outside the cabin. Background technique [0002] The interior of the flight used in civil aviation generally has a communication system for the crew to communicate with each other, that is, the intercom system, and also has a communication system in the cabin to communicate with the tower control center. [0003] During the take-off towing phase, maintenance phase or regular inspection phase of the aircraft, it usually requires the division of labor and cooperation between the personnel inside the cabin and the outside personnel to complete related tasks. In this process, communication between the personnel inside and outside the cabin is naturally required. For example, sometimes the cabin personnel It is necessary to stick your head out to see the gestures of the people ...

Problems solved by technology

[0003] During the take-off towing phase, maintenance phase or regular inspection phase of the aircraft, it usually requires the division of labor and cooperation between the personnel inside the cabin and the outside personnel to complete related tasks. In this process, communication between the personnel inside and outside the cabin is naturally required. For example, sometimes the cabin personnel It is necessary to stick your head out to see the gestures of the people outside the cabin or to go under the cabin to have a voice conversation with the people outside the cabin. This communication method is time-consuming and laborious. It is difficult when there are many people and complicated operations. It is easy to cause safety accidents, resulting in huge economic losses

[0004] In order to facilitate the communication of personnel inside and outside the cabin, wired earphones can be used for communication, but this method not only has a long communication distance, but also the use of cables will bring inconvenience to normal operations, especially when mobile maintenance or multi-person division of labor is required. when
