Abstract

The invention belongs to the technical field of aviation electronics, and especially relates to an aviation recorder and an automatic positioning method. The aviation recorder comprises a floating box and a control box which can separate with each other, wherein a connector is arranged between the floating box and the control box, and the floating box comprises a Beidou / GPS beacon. After the aviation recorder falls into water, the floating box and the control box separate, the floating box floats on the water surface, the Beidou / GPS beacon sends positional information to an external receiving device through antenna exposed on the water surface, and the receiving device accurately position the aviation recorder after receiving the positional information. The aviation recorder mainly solves problems of difficult searching, rescuing and salvage for recorders which fall into the sea after a marine accident occurs to aircrafts, can accurately and timely obtain time falling into the sea and geographic positions, timely salvage evidence for investigation and analysis of the accident, and is quite suitable for emergency rescue for modern aircrafts.

Description

technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to an aviation recorder and an automatic positioning method. Background technique [0002] Aviation recorders are mainly used to provide scientific evidence for accident investigations when aircraft crash, and play an irreplaceable role in analyzing the cause of accidents. Therefore, how to accurately locate the accident location and find the recorder in time will directly affect the accident investigation and analysis. However, existing aviation recorders do not realize satellite emergency search and rescue positioning. Existing aviation recorders mainly realize positioning through methods such as eye-catching colors on the outside, reflective stickers, and installation of underwater positioning beacons and radio beacons. However, when an aircraft crashes into the sea in an accident at sea, it is difficult to find the target through visual inspection. The distance of ...
