Flight record system for plane and data processing method thereof

Abstract

The invention discloses a flight record system for a plane and a data processing method thereof, relates to the technical field of aircrafts, and aims to solve the technical problem involved in monitoring of plane working conditions. The system comprises a ground communication terminal as well as a self-contained power supply, an onboard satellite communication terminal and two trigger switches which are arranged on the plane, wherein the first trigger switch is a mechanical micro switch; the second trigger switch is a bipolar latch Hall switch; the onboard satellite communication terminal is connected with the ground communication terminal through a satellite; the power supply port of the onboard satellite communication terminal is connected to an onboard power supply and the self-contained power supply respectively through the two trigger switches; the first trigger switch is arranged in the undercarriage cabin of the plane, and is triggered to be switched on/off through an undercarriage; the second trigger switch is arranged in a true-airspeed meter, and is triggered to be switched on/off through two magnets arranged on the inner wall of a dial plate; flight working condition data can be transmitted to the ground communication terminal in real time through the onboard satellite communication terminal. The system and the method contribute to ground monitoring of the plane working condition.

Description

technical field [0001] The invention relates to aircraft technology, in particular to a technology of an aircraft flight recording system and a data processing method thereof. Background technique [0002] At present, the aircraft's working conditions are monitored through ground radar monitoring and on-board equipment records during flight. There are many on-board equipment on the aircraft, and the flight recorder plays an important role in analyzing flight data. [0003] The flight recorder, also known as the black box, is one of the special electronic recording devices for aircraft. Sensors are connected to each mechanical part and electronic instrumentation of the aircraft. The black box can record the voice conversation and two hours before the aircraft stops working or crashes. It plays an important role in the investigation of air accidents. However, it is difficult to search and salvage the black box. Sometimes even if the black box is found, it loses its use value b...
