Description
Technical Field
The invention belongs to the technical field of avionics, and particularly relates to a maintenance-free aviation recorder and a state detection method.
Background
The aviation recorder is an important component of a flight parameter system, and mainly records flight data, audio data and vibration data of an aircraft along with the development of a combined recorder at present, so as to support flight accident investigation. Usually, the aviation recorder has the characteristics of strong impact resistance, high-temperature burning resistance and the like, and can ensure that the recorded flight data can be reliably read after a flight accident occurs. However, the chip for recording various types of data inside cannot realize rapid data reading because the chip is wrapped by a special structural member. Therefore, in the daily maintenance process of the aviation recorder, a professional is required to download data by using special flight parameter data downloading equipment so as to judge the running state of the aviation recorder. At present, the typical aviation recorder flight parameter data downloading maintenance mode needs to be equipped with special equipment and personnel, and needs to occupy certain data downloading time.
At present, in the process of using the recorder in the field, maintenance personnel only read and analyze the data of the cache card 6 in the cache recorder 5 after each overhead flight is finished, and the product state of the recorder cannot be determined whether the data is normal or not.
To minimize aircraft ground maintenance time, a cache 5 is typically added to the flight parameter system. The quick access recorder 5 and the aviation recorder respectively receive the data of the flight parameter collector 4 at the same time, and after the flight is finished, the flight parameter data is directly obtained by pulling the quick access card 6 in the quick access recorder 5 (shown in fig. 1 in the cross-linked schematic diagram on the aviation recorder), so that the quick reading of the flight parameter data is realized, and the flight parameter data in the aviation recorder is prevented from being downloaded. However, when the cache recorder 5 normally records the flight parameter data, the phenomenon that the flight parameter data cannot be recorded and the fault is not reported (any device cannot detect the fault by 100%) may occur in the aviation recorder; if the aircraft has serious flight accidents under the condition, the flight data cannot be recorded due to damage of the aviation recorder, and the flight data cannot be protected due to no protective measures of the quick access recorder 5; finally, the aircraft is very likely to fail accident investigation due to the fact that no flight data can support the accident investigation, and immeasurable results are brought. Accordingly, there is a need for an aerial recorder that can achieve maintenance-free and reliable recording of flight data.

The data management module 2 includes a data receiving function sub-module 201, a data comparing function sub-module 202, a data read-back comparison result reporting function sub-module 203, a data processing function sub-module 204, and a data recording interface function sub-module 205. The data receiving function sub-module 201, the data comparison function sub-module 202, the data read-back comparison result reporting function sub-module 203 and the data recording interface function sub-module 205 are all connected with the data processing function sub-module 204, the data recording interface function sub-module 205 is connected with the storage module 3, and the data receiving function sub-module 201 is connected with the onboard flight parameter collector 4.
The power supply module 1 provides a product working power supply and supplies power to the data management module 2.
The storage module 3 stores flight data, audio data and vibration data for accident investigation.
The data management module 2 receives flight data, audio data and vibration data, stores the flight data, the audio data and the vibration data in the storage module 3, performs read-back comparison on the stored data and the received data, and reports a comparison result to the flight parameter collector 4. The data receiving function sub-module 201 includes bus interfaces such as RS422, ARINC 717, HDLC, ethernet, etc., and is mainly used for receiving flight data, audio data, and vibration data, and sending the flight data, audio data, and vibration data to the data processing function sub-module 204. The data processing function sub-module 204 mainly receives the flight data, the audio data and the vibration data sent from the data receiving function sub-module 201, records the processed data to the storage module 3 through the data interface function sub-module 205, reads the flight data, the audio data and the vibration data which are just recorded through the data interface function sub-module 205, and sends the flight data, the audio data and the vibration data to the data comparison function sub-module 202. The data comparison function sub-module 202 compares each type of data with the received data, and then the result is stored in the data read-back comparison result reporting function sub-module 203 and reported to the flight parameter collector 4 every second, and the status word is cleared after reporting; the data interface function sub-module 204 is mainly used for data exchange of flight data, audio data and vibration data between the data management module 2 and the storage module 3. The data download interface functional sub-module 205 is used for downloading flight data, audio data and vibration data after the flight mission is finished.
The method for detecting the state of the maintenance-free aviation recorder comprises the following implementation processes:
when the flight parameter system works, the flight parameter collector 4 acquires the fault state of the recorder every 1 second, the data readback comparison result reporting functional sub-module 203 in the maintenance-free recorder reports the readback comparison result state word to the flight parameter collector 4 and then clears the state word, and the result of data readback comparison in the next second is continuously recorded until the flight is finished.
After the flight is finished, the working state of the aviation recorder can be judged only by interpreting the flight data recorded by the quick access card 6 in the quick access recorder 5 without specially downloading the flight parameter data of the aviation recorder, so that the maintenance-free aviation recorder is realized.
Because the data recorded by the quick access card 6 in the quick access recorder 5 is the same as the data recorded in the recorder, a user needs to read the data in the quick access card 6 after each overhead flight task is completed during the maintenance of the outfield, and the state of the airplane in the whole flight process and the accuracy of the recording of various types of data in the recorder can be obtained by analyzing the data recorded in the quick access card 6, so that the state of the recorder can be quickly detected.
