Aircraft flight recording system and its data processing method

Abstract

An aircraft flight recording system and a data processing method thereof relate to the technical field of aircraft and solve the technical problem of monitoring the operating conditions of the aircraft. The system includes a ground communication terminal, a self-contained power supply installed on the aircraft, an airborne satellite communication terminal, and two trigger switches. The first trigger switch is a mechanical micro switch, and the second trigger switch is a bipolar latch. type Hall switch; the airborne satellite communication terminal is connected to the ground communication terminal through the satellite, and the power port of the airborne satellite communication terminal is respectively connected to the airborne power supply and the self-contained power supply through two trigger switches; the first trigger switch is installed at the start of the aircraft In the landing gear compartment, the landing gear triggers its opening and closing. The second trigger switch is set in the real airspeed indicator, and its opening and closing are triggered by two magnets set on the inner wall of the dial; The data is sent to the ground communication terminal in real time. The system and method provided by the invention are beneficial to ground monitoring of aircraft working conditions.

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...

Problems solved by technology

[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 is used for flight experiments and accident analysis, and 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 because of its damage.

[0004] In addition, there are many on-board communication devices on the plane that can be manually turned off, so that when unexpected situations such as hijacking occur, it is easy to cause the plane to lose contact with the ground, and important flight record data will be lost, thus increasing the difficulty of searching for the plane
