This system, as the closest in technical essence and the achieved result, is taken as the closest analogue (prototype).

The disadvantages of this system are limited functionality, due to the inability to provide the pilot with current flight information, which negatively affects the efficiency of decision-making and the need to use ground-based processing facilities.

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

The data recording system consists of a unit 1 for collecting and converting information made on the basis of switch microcircuits, analog-to-digital converters and microprocessors, a protected drive 2, made on the basis of non-volatile memory chips, a control panel 3, a control unit 4, 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, controller 5 of the protected storage a computer based on a microcomputer with communication interfaces with the rest of the system, a unit 6 for processing audio information, which can be built on the basis of specialized microchips codecs and a microprocessor with built-in special software for processing audio information, a unit 7 for collecting information, which includes a microprocessor and an adapter for recording information on a removable cartridge with non-volatile memory, which can be used as a standard PCMCI card, and flight processing unit 8 Info provided on the basis of a microcomputer with sewn in her algorithms, processing and converting flight information into a form suitable for display (it can be a mnemonic, graphical, tabular and other other form of presentation, convenient for the operator).

The data recording system operates as follows.

Information (data) coming from the sensors and systems of the monitored object to the information inputs 1, 2, 3 of block 1 is converted into a single digital form in it and stored in the random access memory of block 1. At the same time, a message is generated from the received information to be written to the protected drive 2 in the form of an information frame consisting of a set of sync words and information words.

The program for processing incoming information, the program for connecting sensors and systems, the frequency of their polling, the structure of the information frame formed by block 1, are developed for each specific application of the registration system.

Identification data (block numbers, date, astronomical time, etc.) are input to control input 4 of block 1 from the output of console 3, which are also converted for recording into information frames. Information frames from the first output of block 1 go to the first input of controller 5, in which they are converted to the form required for writing to the protected drive 2, sequentially transferred and written to the memory of drive 2. The entire memory area of drive 2 is divided into the information area, where all recorded information, and service, where special information and programs are stored, necessary for linking the registration system to a specific control object.

In each recording cycle, the correctness of recording information is monitored by reading and transmitting it via communication lines from output 1 of drive 2 to the second input of controller 5 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 2, the recorded information (data) is recorded only in serviceable memory elements.

In addition, if the number of defective elements exceeds the permissible level, a failure signal is generated in the controller 5 from the registration path, which is transmitted from the third output of the controller 5 to the first input of the control unit 4.

In block 4, upon receipt of this signal, a system failure signal is generated, which is fed to the third output of the control block 4 for presentation to the operator through the information display system.

Simultaneously with the transmission of information frames from the first output of block 1, information in the form of binary code from its second output goes to the second input of control unit 4, the first input of which from the control unit 5 receives the calibration characteristics of the sensors read from the service area of the drive memory 2 and operational limitations. This information is processed in block 4 in order to identify the outputs of the object control modes beyond the permissible limits. When such situations are detected in block 4, signals are generated that from the first output of control block 4 go to the third input of controller 5 for subsequent registration in the memory of protected drive 2, and to warn the operator about the exit of control modes of the object beyond the permissible limits and about the appearance of emergency and pre-emergency situations, these signals from the output 3 of the control unit 4 are fed to the input of the information display system.

In addition, test signals generated in block 4 are periodically fed to the fifth input of block 1 from the second output of block 4. These signals are processed by block 1 similarly to information from sensors, and the results are transmitted to the second input of block 4. Block 4 compares the processing results with the tests and according to the comparison results it generates a service / failure signal of the information collection and conversion unit 1. This signal from the third output of block 4 is supplied for presentation to the operator, and from the first output of block 4 to the fourth input of controller 5 for registration in the memory of drive 2.

In block 6, the sound information arriving at its inputs from the control panel and microphones is converted to digital form, processed using special algorithms to reduce the amount of memory required for its registration (information compression), and fed from the output of block 6 to the 5th input of block 5.

Depending on the requirements for the compression ratio and signal quality during subsequent ground processing (signal distortion level, signal to noise ratio, etc.), various algorithms for processing audio information can be used, including those widely known as MPEG, CELP, ADPCM and others.

In block 5, the information received from block 6 is converted to a form convenient for registration in the protected memory of block 2, similar to parametric, with the information coming from individual audio channels being written to separate zones in the information area of the memory of block 2, specially allocated for this.

In the process of converting into recorded audio information, time stamps are periodically added, obtained from the parametric information supplied to the input 1 of block 5, or generated by block 5. In this case, the same marks are also included in the recorded parametric information.

At the same time, all the information recorded in the protected drive in the order of its receipt is transmitted from the output of block 4 to input 2 of block 7, in which it is recorded on a removable cartridge 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 2 is created in the memory of the removable cartridge of unit 7. Moreover, the entire memory area of the removable cartridge allocated for recording information recorded in block 5 is divided into separate zones by analogy with the protected memory drive.

In addition, at the input 1 of block 7, the output 3 of block 1 receives additional information that does not need to be recorded in the protected drive 2, but which can be used when servicing the aircraft for more detailed monitoring of the operation of the equipment of the aircraft and diagnosing its condition, as well as for analysis of the performance of the flight mission, evaluation of aerobatics.

In the event of an emergency, in the event of a system failure, as well as during various operations to check the system’s operability, the information accumulated in the protected drive 2 can be read by the protected drive controller 5 and transmitted from its third output to the input of ground-based information processing equipment. The software allows not only to completely read all the registered information, but also to selectively read from the service area of the memory of the drive 2 and record through the controller 5 of the protected drive into the service area of the memory of the drive 2 of the service information: calibration characteristics of sensors, operational limitations, etc.

The information generated in the controller 5 for the ground processing system, arrives simultaneously through the 5th output of the controller 5 to the input of the flight information processing unit 8. Depending on the functional purpose of the aircraft (training, marine, sanitary) in block 8, 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 block 4, the 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.

On the ground, an airplane technician can provide calibration and calibration of sensors, search for failed units using an indication, etc., which reduces the preparation time for a second departure.

Thus, the introduction of the flight information processing unit 8 made it possible to expand the capabilities of the registration system, providing the crew with the current processed flight information and reducing operating costs.
