In flight, the system operates in the “Registration mode, in ground conditions - in all of the above modes of operation specified from the display and control panel 5, for example, using the dial switch, while the“ Registration mode has the highest priority in relation to other modes and is set automatically (for example, by the signal “squeezing the chassis) or manually, using the switch.

Service data (board number, date and flight number) from the data input panel 3, the signals of the sensors and systems of the object received at the information inputs 1,2, ...., p of the unit for collecting and converting information 1 are converted into a digital code in it, then data packets consisting of 256 information 9-bit words, accompanied by frame and clock sync pulses from its output in the form of a parallel code with a frequency of 256 or 512 Hz, are fed to the first input of the protected magnetic storage 2 and to the second input of the recording, monitoring and analysis unit 4.

The fourth and fifth inputs of the registration, control and analysis unit 4 receive data packets consisting of 10-11 bit words, accompanied by frame and clock sync pulses in the form of a parallel code with a frequency of 2000 -: - 3000 words / sec from the navigation system and the radio monitoring complex, respectively .

The sixth and seventh inputs of the registration, control and analysis unit 4 receive data in the form of a serial code of the RS232 standard with a frequency of 38400 Hz and signals of second time marks of UTC level

TTL from the information output and sync output of the satellite radio navigation system with a frequency of 1 or 10 Hz.

In the "Registration" mode, the protected magnetic drive 2 records the data arriving at its first input on a moving magnetic tape along 12-13 tracks and generates a generalized signal of serviceability of the conversion and recording information path at + 27V and a frequency of 1 Hz, which from its first output arrives at the input of the data input panel 3 for indication by a signal lamp.

At the same time, the registration, control and analysis unit 4 registers (writes) to its own memory module, executed on flash memory microcircuits, the data postzschi on its second, fourth, fifth, sixth and seventh inputs, and also gives a signal "record level + 27V, 1 Hz per signal lamp for indication on the display and control panel 5.

In accordance with the specified mode of operation and the selected stream number, the registration, control and analysis unit 4 checks the integrity of the received packets (frames), as well as checks the received information words for parity (if the information word contains the sign “parity”) and gives a digital indicator remote indie operation and control 5 data on the number of the monitored stream Nn, the number of NCK is the number of failed packets (frames), the number of NK is the total number of packets (frames) received, the ratio is 100%, the number of NCC is the number of parity information word failures, the number of NC - the total number of information words accepted and the ratio --- 100%, allowing to judge the serviceability of the formation, transmission and reception of a controlled stream.

In the “parameter control” mode using the keypad of the display and control panel 5, the number of the received data stream Nn and the word number in the Ncn packet are set. In accordance with the specified operating mode and the selected parameters Nn and Ncn, the recording, monitoring and analysis unit 4

gives to the digital indicator of the display and control panel 5 data on the stream number Nn, the word number in the packet (frame) Ncn, as well as the physical or frame value of the parameter - RNV mode “Entering service data into the read-only memory of the recording, control and analysis unit 4 s the keyboard of the display and control panel 5 by the command “Enter, the calibration data of the parameters recorded by the protected magnetic drive are entered, while from the output of the registration, control and analysis unit 4 to the digital indicator of the display and control panel Ia 5 outputs the number Nn stream in NCR room words packet and the value of the input parameter - PB.

In the “Preparation of the memory module by command from the display and control panel 5 mode, the registration, control and analysis unit 4, in accordance with the program laid down in it, writes the hexff information data file oxff to its own memory module. After the recording is completed, the registration, control and analysis unit 4 issues a message indicating that the memory module is ready for registration to the display and control unit 5.

In the "control of the memory module by command from the display and control panel 5 mode, the recording, control and analysis unit 4, in accordance with the program laid down in it, writes control values to its own memory module, after which it reads the recorded checksums and compares the recording amounts and reading. When they coincide, the registration, control and analysis unit 4 issues a message about the health of the memory module to the display and control unit 5.

The express analysis mode is carried out after the flight. To do this, on the display and control panel 5, the number of the recorded flight data stream Nn, which is subject to express analysis, is selected. After that, the registration, control and analysis unit, in accordance with the program laid down in it, identifies the events of the aircraft’s flight in flight for operational limitations, the events of the failure of aviation equipment in flight and deviations in its operation, which do not allow the aircraft to be launched into the next flight, as well as events dangerous and gross errors and violations of the flight crew during piloting, combat use of the aircraft and control of its equipment. The identification of these events is carried out in accordance with the algorithms given in the book Automated Processing of Flight Information, Moscow, Military Publishing House, 1995. Data on the identified

events (time, number and event content) are sequentially issued to the display and control panel 5, where they are displayed on the indicator screen.

In the “Overwrite using the switch on the front panel of the display and control panel 5, the“ Fast-forward. According to this signal, the data recorded on it are read from the magnetic tape of the protected magnetic drive 2 and transmitted to the third input of the registration, control and analysis unit 4, where, in accordance with the program, they are received and service information is generated from them (board number, date, number flight), time (hours, minutes, seconds), as well as control parameters; they are analyzed, formed and issued to the display and control panel 5 messages on the technical condition of the protected magnetic storage 2 for its indication.

When you turn on the toggle switch “Record on the display and control panel 5, the data read from the magnetic tape of the protected magnetic drive 2 is recorded.

The registration, control and analysis unit 4, as well as the display and control unit 5 can be performed on a typical domestic and foreign element base. So, as a microcomputer included in block 4, one can use, for example, the built-in single-board computer BAGET-83 of the domestic development of the PC-104 standard, made on the basis of a processor module with a clock frequency of 100 MHz and providing real-time object control.

As a memory module included in block 4, a PCMCIA standard FLASH card with a capacity of 96-880 MB can be used, which is interfaced with the SANDISK controller MSMJ104D.
