The disadvantages of this system are limited functionality due to the lack of registration of flight video information in a secure drive, which greatly complicates the investigation of a flight accident, and for training flights, the investigation of a flight mission.

The drawing shows a structural diagram of a data recording system.

The data recording system contains a unit 1 for collecting and processing information (hereinafter referred to as BSOI1), consisting of modules: module 2 for collecting and converting, based on switch microcircuits, analog-to-digital converters and microprocessors, control module 3, which, in particular, can be built on the basis of microprocessor sets, digital-to-analog converters as sources of analog test signals and shapers of one-time test signals, flight information processing module 4, based on microE VMs with the algorithms for processing and converting flight information embedded in it into a form convenient for display (this can be a mnemonic, graphical, tabular, and other other form of presentation of information convenient for the operator), module 5 of the total operating time of the BSOI1 block; operational on-board drive 6 (hereinafter referred to as EBN6), which includes a removable cartridge with non-volatile memory, which can be made on the basis of a microprocessor, for example, a signal processor type DSP or processor type CPU-CORE and module 7 of the total operating time EBN6; protected on-board drive 8 (hereinafter referred to as ZBN8), consisting of a protected drive controller 9 made on the basis of a microcomputer with communication interfaces with the rest of the system, a sound information processing module 10, which can be built on the basis of specialized codec chips and a microprocessor with a built-in special software for processing audio information, a protected drive 11, made on the basis of chips with non-volatile memory and module 12 of the total operating time ZBN8; additional on-board drive 13 (hereinafter referred to as DBN13) which includes a chip with non-volatile memory, which can be performed on the basis of a microprocessor, for example, a signal processor of the DSP type or a processor of the CPU-CORE type and a module 14 of the total operating time of DBN13; video information processing unit 15 (hereinafter referred to as BOV15) with a cumulative operating time module 16. BOV15 converts information from the video recording system (according to the selected compression algorithms) into a serial code (for example, ETHERNET), which, through a distributor (of the HUB type) in block БСОИ1, enters block ЗБН8 .

Modules 5, 7, 12, 14, 16 of the total operating time of blocks BSOI1, EBN6, ZBN8, DBN13, BOV15, respectively, are non-volatile memory, in which the average MTBF and the MTBF of Top are used to confirm reliability indicators and production control resource blocks.

The data recording system operates as follows. Through the information inputs of BSOI1 and the module 10 for processing audio information, the entire volume of information intended for registration in the protected drive 11, as well as for storing copies of the recorded information in the memory modules EBN6 and DBN13, enters the system. The video information is processed in the BOV15 block, compressed according to the specified algorithms, converted into a serial code, and through the BSOI1 block it enters the ZBN8 block for registration in the protected drive 11.

The parametric, sound, and video information entering the system undergoes the necessary processing in module 2 of BSOI1, in module 10 of ZBN8, and in block 15 of BOV goes to controller 9 of the protected drive.

In the process of converting into recorded audio and video information, time stamps are periodically added, obtained from the parametric information received in module 9 of block 8 from module 2 of block 1. These same marks are also included in the recorded parametric information.

The information received in the controller 9 of the secure drive is formatted in it and transmitted to the secure drive 11. In each recording cycle, the correctness of the information is recorded by reading and transferring it via a shared bus from the drive 11 to the input of the controller 9 for comparison. When errors are detected, several repeated write / read cycles are performed. In case the recording is carried out with an error, a decision is made about the defect of the memory element and the recording is made to the neighboring memory element. The number of the defective element is recorded in a specially allocated part of the service area of the memory of the drive 11, the recorded information (data) is recorded only in serviceable memory elements.

In addition, if the number of defective elements exceeds the permissible level, a signal of a failure of the registration path is generated in controller 9, which is transmitted from controller 9 through the output of ZBN8 to the input of BSOI1 to control module 3. When receiving this signal in module 3, a system (block) failure signal is generated, which comes from the BSOI1 output for presentation to the operator through the information display system and to module 2 for generating an information frame and subsequent recording to the protected drive 11.

The information generated in the controller 9, simultaneously from the output of the ZBN8 enters the input BSOI1 and then to the module 4 for processing flight information. Depending on the functional purpose of the aircraft (training, naval, military, sanitary) in module 4, through wired visualization algorithms, the input information is converted into an appropriate list of parameters of a certain sequence and form, taking into account color coding, convenient for display. Through BSOI1 visualization information is transmitted to the on-board information display system. The amount of information necessary for output to the on-board display system is determined by the pilot in flight, for example, it can be information about flight and technical limitations during training flights, on the condition of on-board equipment, on the availability of weapons, fuel, separation, etc., which allows you to quickly make decisions.

At the same time, all information (except for video information) recorded in the protected drive 11 is transmitted in the order of its receipt from the output of ZBN8 through BSOI1 to the inputs of EBN6 and DBN13, in which it is recorded on modules with non-volatile memory. The dubbing is performed under software control in such a way that an exact copy of the contents of the protected drive 11 is created in the memory modules EBN6 and DBN13. Moreover, the entire area of the memory modules EBN6 and DBN13 allocated for recording information recorded in the protected drive 11 is divided into separate zones by analogy with the memory of the protected drive 11. The control of writing to the non-volatile memory DBN13 and EBN6 is performed similarly to the control of writing to the non-volatile memory of the protected drive 11.

The exchange of information between BSOI1 and EBN6, ZBN8, DBN13, BOV15, an on-board information display system, ground processing equipment, a control panel, an on-board radio digital converter connected by bi-directional communication via a serial code, is carried out by packets indicating the packet length and the checksum of the transmitted information in the packet . The receiving unit checks the received information on the length of the packet, the checksum and gives a signal of correct reception to the transmitting unit. If there are errors in reception, the transmitting unit repeats the issuance of the information packet.

The presence of bidirectional communication between all blocks and systems allows you to control the correctness of the received information, control the current condition by the operator with the recording of the health signal in a secure drive 11. The total operating time of the BSOI1, EBN6, ZBN8, DBN13, BOV15 blocks is recorded when the power is turned on, the total MTBF in flight - by the presence of an engine start command.

The information recorded in the non-volatile memory of modules 5, 7, 12, 14 and 16 of the total operating time of the BSOI1, EBN6, ZBN8, DBN13, BOV15 blocks allows you to control the life of the blocks for their timely replacement, is used to confirm reliability indicators (operating time in flight).

DBN13 is located in a small-sized building and is part of a portable emergency stock (hereinafter referred to as NAZ), which contains essential items in case of a flight accident. In a flight accident, the NAZ shoots back with the pilot’s seat and, together with the pilot, lands (splashed) on the halyard, so it is relatively easy to find.

Given that modern drives use high-capacity memory chips, it is therefore possible to record flight video information for several hours. During long flights, video recording is divided programmatically into separate fragments. If the memory in the block ZBN8 allows you to record continuously 3 hours of video information and the flight lasts less than 3 hours, then the entire flight is recorded. During long flights, the algorithm for recording video information is set programmatically. For example - 3 hours recording is continuous, then priority is given to short recordings of video information (3-5 minutes) according to the presence of signs that the parameters are outside the permissible limits, the rest of the information is erased in a ring, while the final phase of the flight always remains 20-30 minutes.

Thus, the presence of an additional video information processing unit containing a cumulative operating time module connected via a bi-directional serial channel with an information collection and processing unit, with a programmable algorithm for recording video information in a secure on-board drive, allows you to save flight video information (together with information about the state of equipment, aircraft systems and service information), which significantly increases the reliability of processing flight information regarding flight Denmark and during the investigation of an accident or accident, and also reduces the time of investigation of a flight accident.
