Maintenance-free aviation recorder and method for detecting states

Abstract

The invention belongs to the technical field of avionics, and particularly relates to a maintenance-free aviation recorder and a method for detecting states. The maintenance-free aviation recorder comprises a power module [1], a data management module [2] and a storage module [3]. Power can be supplied to the data management module [2] by the power module [1], and the data management module [2] comprises a data receiving functional slave module [201], a data comparison functional slave module [202], a data read-back comparison result reporting functional slave module [203], a data processing functional slave module [204] and a data recording interface functional slave module [205]. The method which is a maintenance-free method for the aviation recorder includes storing data received by the recorder in the storage module [3] protected by protective shells; reading back data and comparing the data to the received data; reporting comparison results to a flight parameter acquisition unit [4]. The comparison results are used as state words. The maintenance-free aviation recorder and the method have the advantages that the ground maintenance time of aircrafts can be effectively shortened, and accordingly the maintenance-free aviation recorder and the method have excellent economic benefits.

Description

technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to a maintenance-free aviation recorder and a state detection method. Background technique [0002] The aviation recorder is an important component of the flight parameter system. With the development of the combined recorder, it mainly records the flight data, audio data and vibration data of the aircraft to support the investigation of flight accidents. Generally, aviation recorders have the characteristics of strong impact resistance, high temperature fire resistance, etc., which can ensure that the flight data recorded after a flight accident can be read reliably. However, the chips that record various types of data inside cannot achieve fast reading of data because they are wrapped by special structural parts. Therefore, during the daily maintenance of the aviation recorder, professionals are required to use a special flight parameter data download device to downl...

Problems solved by technology

However, when the cache recorder 5 normally records the flight parameter data, the aviation recorder may appear to be damaged and cannot record the flight parameter data and does not report a fault (any equipment cannot 100% detect fault); In the case of a serious flight accident, the aviation recorder cannot record the flight data due to damage, and the cache recorder 5 cannot protect the flight data due to no protective measures; finally, the aircraft is very likely to fail the accident investigation due to the lack of flight data that cannot support the accident investigation. , with immeasurable consequences
