Wireless headset and communication system between inside and outside of cabin

Abstract

The invention discloses a wireless headset and a communication system between the inside and the outside of a cabin. The wireless headset is convenient to use and can be connected with an interphone system of an airplane. The communication system between the inside and the outside of the cabin comprises the interphone system of the airplane, a wireless receiving and transmitting device and multiple wireless headsets. The interphone system of the airplane is connected with an airplane data port of the wireless receiving and transmitting device through an airplane service panel and used for transmitting voice signals inside the cabin to the wireless receiving and transmitting device and receiving voice signals outside the cabin, wherein the voice signals outside the cabin are transmitted by the wireless receiving and transmitting device. The wireless receiving and transmitting device is connected with the airplane service panel in a matched mode, controlled by the airplane service panel, used for processing the voice signals inside the cabin and then modulating the voice signals to wireless carrier waves of preset frequency and further used for receiving and processing the voice signals outside the cabin and then transmitting the voice signals to the interphone system of the airplane, wherein the voice signals inside the cabin are provided by the interphone system of the airplane, and the voice signals outside the cabin are transmitted by the wireless headsets. Voice communication staff inside and outside the cabin can be convenient, and potential safety hazards of the airplane are reduced.

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
