Device and method for initiatively reporting position information during aircraft disaster

Abstract

The invention discloses a device and a method for initiatively reporting position information during aircraft disaster. The method includes judging whether power supply condition information of an onboard power interface or communication state information among a plurality of different devices initiatively reporting the position information during the aircraft disaster has abnormal conditions in real time; on yes judgment, enabling a controller to transmit satellite location information, device coding information, the communication state information among the plurality of different devices initiatively reporting the position information during the aircraft disaster and the power supply condition information of the onboard power interface to a preset external receiving device through a satellite till power supplies of emergency batteries on the devices initiatively reporting the position information during aircraft disaster are used up.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a device and a method for actively reporting position information when an aircraft is in disaster. Background technique [0002] Ensuring flight safety and preventing flight accidents are the primary tasks of the aviation industry. With the advancement of science and technology, the safety of air transportation has been greatly improved. However, the incidence of aviation accidents can be continuously reduced but cannot be completely avoided. The characteristics of the operation of the aircraft itself determine that once an accident occurs, it is often catastrophic and will cause significant loss of personnel and property. At this time, it is very important to locate the aircraft in disaster and put it into rescue as soon as possible to reduce the loss of personnel and property. [0003] Existing aircrafts are generally equipped with information broadcasting sys...

AI Technical Summary

Problems solved by technology

In reality, there are many times when there is no base station on the ground or the base station fails to cause information transmission failure;

[0007] Black box or ELT systems broadcast as an active signal in an emergency and require the receiver to be close enough to be detected, so are not very reliable

When a major disaster occurs in the aircraft (such as disintegration in the air), the pilot often fails to send out a radio signal, and the final fall is too large to make it difficult to find the black box in a short time, making the rescue work lag

[0008] In addition, the automatic response system in the prior art is likely to stop working due to damage to the airframe, power supply stop, etc.; at the same time, the aircraft in the prior art broadcasts the position of the aircraft during normal operation, from the moment of disaster or even disintegration of the aircraft until it lands The time period of falling into the water is the information black window period of the existing technology

During this time period, the aircraft cannot implement any form of information emergency transmission operation
