In the algorithms of the T-235-1L-1 LT1.600.012 hardware, information is exchanged at C1 junctions of various categories (types) with various types of signal modulation:

- C1-FL with bi-pulse coding (BI);

- C1-PM with frequency modulation (FM);

- C1-I with bi-pulse coding and an amplitude of 12 V for “Crossbow” type radio equipment.

In bi-pulse coding, the symbols “0” and “1” of the data signal are transmitted over the clock interval by two pulses of equal duration and opposite polarity (10 or 01).

The alternation order of the polarity of the pulses compared with the previous clock interval does not change when transmitting the character "1" and changes when transmitting the character "0".

When working with frequency modulation, the characteristic frequencies of 2100 Hz are used - for the symbol "0" and 1300 Hz - for the symbol "1".

Work in the algorithms of the T-235-1L-1 equipment provides for the modes “OK ОДК1”, “ОК ОДК2”, “ОК ОДК2-1”, while the length of the code combinations is 69 unit elements.

When working with ASPD-U equipment, the exchange over channels (radio, wire) is performed by code combinations of 40 unit elements in length with the structure used in ASPD-U equipment in the “Single” or “Double” modes.

A marker synchronization method is used in cycles, that is, a correction signal is present in each code combination, takes four bits (from 37 to 40 bits) and corresponds to combinations 0010 or 1101, each of which is transmitted through one cycle.

When working with relative phase modulation (OFM) used for ASPD-U equipment, when transmitting the “1” symbol, the carrier phase does not change compared to the previous clock interval, and when transmitting the “0” symbol, it changes by 180 °.

The unit interacts with the computer via the RS-232C interface (GOST 18145-81), the electrical parameters of the RS-232C interface signals meet the requirements of GOST 23675-79 in accordance with the protocol of information and technical interface of the H911 unit with data terminal equipment (OOD.)

The choice of the channel of interaction with the computer (COM1 or COM2) is set by the COM switch on the front panel of the unit.

The TNA equipment is coupled to OOD via COM1, COM2 in accordance with the protocol of information and technical interaction.

Functional control of the receiving and transmitting channels at the junction of C1 and the communication channels COM1 and COM2 in the unit is carried out under the control of an external computer.

An additional (standby) module H911.02 is installed to replace a failed module of the same type.

The transmitter and receivers from the backup module are not connected to the external connectors of the unit and can exchange information only in self-monitoring mode or internal loopback.

H911.05 module

The H911.05 module is a secondary power source that provides power to the unit due to the formation of the output voltages 5 V ± 0.25 V by the MDM 30-1B05M, MDM 30-2V1212M and MDM 15-1V12M modules; 12 V ± 0.6 V; minus 12 V ± 1 V; (12 V1 ± 0.6) V from the input voltage (27 + 3, minus 4) V. supplied to the external “27 V” (XP1) connector

Description of the operation of the receiver and transmitter of the ADF module, operating in the T-235-1L algorithms

The structural diagram of the transmitter (PRD), working in the algorithms of the APD T-235-1L, is presented in figure 2.

RFI provides the formation of a sequence of signals that determine the duration of code combinations and time relationships within the code combination.

RUPRD is a programmatically accessible register, with the help of which the computer manages the operating modes of the PRD

DB - for receiving and storing code combinations received from computers.

After filling in the database in the PRD, the process of initial synchronization begins. FSLKK produces "points", i.e. a combination of ones and zeros in the length of two code combinations to ensure synchronization over single elements, and a combination of phase start (KPF) to ensure cyclic synchronization. CFP is a part of the recurrence sequence with the generatrix polynomial X ⁸ + X ⁶ + X ⁵ + X ⁴ +1 in the length of one code combination. Depending on the specified operating mode ("ОДК-1" or "ОДК2"), one or two (direct and inverse) FPCs are sent to the communication channel in place of the 96th (96th and 97th) code combinations.

In FINFKK, service unit elements are added to the information unit elements from the database, which are determined depending on the operating modes of the PRD. The code combination thus formed is complemented by a sequence of test elements with CD.

CD provides the introduction of redundancy in the code combination in order to protect the transmitted data from errors that occur in the communication channel. For this, the information part of the code combination with the database is divided into the generating polynomial Q (X) = X ^l6 + X ¹² + X ⁵ +1, the obtained remainder of the division determines the sequence of test elements.

The generated service or information code combinations through KM1 are received by the MFDM and MDBI.

In MDBI, the formation of a bi-pulse signal is based on encoding a logical unit with a 10 or 01 bit, and when going to a logical zero, it is the inversion of the previous one.

In FDM, the conversion of signals arriving in the form of single elements into frequency-modulated signals is based on the method of switching two frequencies. For the symbol “0” the characteristic frequency is 2100 Hz, for the symbol “1” - 1300 Hz.

The PS provides additional BI-modulation of the bi-pulse signal to ensure oncoming operation of radio stations such as "Aqueduct" and "Crossbow".

KM2, depending on the type of modulation specified in the RRDRD and the PS attribute, transmits a signal from the MFDM, MDBI and PS to the output circuits of the PRD.

FSPRK generates a signal received from the modulator in shape and amplitude for transmitting it after additional amplification with the help of US on wired communication channels.

FSRK generates a signal received from the modulator in shape and amplitude to transmit it to a given RRRD radio station.

UKMS converts the signal received from FSRK into the signal of the junction specified in the RRRD: C1-ТЧ, С1-ФЛ - for radio stations of the type “Aqueduct” (RS (ТЧ), RS1 (ФЛ) - RS4 (ФЛ)), С1-И (paraphase output amplitude of 12 V) for "Crossbow" (PC (IMP) -type radio equipment. The UKMS contains matching elements that ensure coordination of the output impedance at the points of connection to communication lines.

The code combination generator provides the formation of the code combination structure in the “ОДК1” and “ОДК2” modes, the length of which is 69 unit elements.

In the “ОДК1” mode, the transmitter provides a transmission mode with the issuance of two code combinations of “points” (a sequence of alternating ones and zeros) and one combination of phase start (KPF) during initial synchronization, as well as one KPF in place of each 96 code combination in the block of transmitted data to work with the T-235-1L-1 equipment operating in the OK OK ODK-1 exchange mode (message types Address, Circular, Silence).

After the termination of the receipt of information from the OOD, the transmitter transmits “Silence” code combinations to maintain a connection with the subscriber.

In the “ОДК2” mode, the transmitter provides a transmission mode with the issuance of two code combinations of “points” and two KPPs (inverse and direct) during initial synchronization, as well as two KPPs (inverse and direct) in place of each 96 and 97 code combinations in the block of transmitted data to work with T-235-1L-1 equipment operating in the “OK ОДК-2” exchange mode.

After the flow of information from the OOD has ceased, the transmitter, in order to maintain a connection with the subscriber, transmits “Silence” code combinations, that is, it ensures operation without disconnecting the channel.

The "ОДК2-1" mode is similar to the "ОДК2" mode except that upon termination of the receipt of information from the OOD, the transmitter does not support connections with the subscriber and does not transmit the "Silence" code combinations, that is, the mode with the channel disconnected is provided.

In this case, in the absence of data from the OOD, the channel is broken, that is, the transmitter stops transmitting signals to the communication channel and the radio is turned off for transmission.

The block diagram of the receiver (PFP), operating in the algorithms of the ADF T-235-1L, is presented in figure 3.

RUPRM is a programmatically accessible register with the help of which the computer manages the operating modes of the PfP.

KM1 and KM2, depending on the operating mode specified in the RUPRM, switch the signals of the input channels (wired channel or with a given radio stations).

The frequency-modulated signal arriving from the communication channel passes through the PF and UARU, with the help of which a limitation on the frequency of the input signal and interference is provided, that is, normalization of the input signal and interference on the frequency. Further, the amplifier-limiter provides the normalization of the signal in amplitude.

DMDM restores the information sequence from a frequency modulated signal. In the demodulator, the restoration of the information sequence is carried out by counting the number of half-periods (transitions) of the received signal for a time equal to the duration of a single element.

DMDBI restores the information sequence from a bi-pulse signal by multiplying the input bi-pulse signal with a delay of a time equal to the duration of the dibit.

The PS carries out additional demodulation of the bi-pulse signal when organizing the oncoming operation of the Arbalest type radio stations and the Aqueduct type radio stations.

TCB generates sequences of pulses that determine the duration of the code combinations and time relationships within the code combination, provides synchronization by single elements of the code combination, performs automatic tuning of the clock frequency of the PFP, synchronizes the operation of all PFP nodes.

A DCS for synchronizing PfP cycles analyzes the resulting code combination and, upon detection of a CPF, it returns the TCB to its initial state and sets the synchronization flag in the PC register.

From the DMD demodulator, an informational 69-bit sequence of pulses enters the database data buffer, where it is converted into a sequence of data bytes intended for delivery through a PCI bus controller to a computer. At the same time, the information sequence from the demodulator passes through the DCD, designed to detect errors in the information coming from the communication channel. In DCD, the received information is divided into the generatrix polynomial Q (X) = X ¹⁶ + X ¹² + X ⁵ +1. In the absence of errors in the information part of the code combination, the remainder from division must be equal to zero. If the remainder of the division is not equal to zero, then the DCD generates an error signal, which is recorded in the PC status register.

Through KM4 information from the database or PC is issued through the RS-232C controller in the computer.

Description of the operation of the receiver and transmitter of the ADF module operating in the ASPD-U algorithms

The structural diagram of the transmitter (PRD), operating in the ASPD-U algorithms, is presented in figure 4.

The frequency divider DF generates from a frequency-stabilized pulse from a crystal oscillator G the frequency of the reference carrier wave 1873 Hz and the frequency of the clock pulses equal to the speed of information transmission in the channel (234 bit / s or 468 bit / s).

The operating modes of the ASD-ASP-U PRD are controlled by a computer via the RS-232C interface through a programmatically accessible control register of the RU.

A block of information for transmission to the communication channel byte-by-bit comes from the computer through the RS-232C controller and is entered into the database data buffer. The FKK code combination generator under the control of the BS synchronization block converts the information from the database into a serial code, and after the last bit of the data block has been transmitted, the combination of the correction signal coming from the FCC correction signal generator is added to the information stream. A fully formed code combination is fed to the FM phase modulator, which converts the discrete signals of the transmitted information into a sinusoidal signal with relative phase modulation. In this case, signals with a frequency of 1873 Hz are used as a signal carrier of information.

The phase-modulated signal is fed to the electronic switch KM. The switch provides the issuance of a block of information through the output amplifiers-shapers in one of the communication channels.

The block diagram of the receiver (PFP), operating in the ASPD-U algorithms, is presented in Fig.5.

Information from one of the communication channels through the input electronic switch KM in the form of a phase-modulated signal is fed through the input transformer TR to the PF bandpass filter tuned to a carrier frequency of 1873 Hz. The automatic control unit UARU provides stabilization of the input signal in amplitude. The stabilized input signal is supplied to the background voltage driver, where the phase of the reference carrier frequency of the receiver is adjusted along the edges of the input information.

The phase detector PD is designed to determine the phase of the elementary transmission of the received information. Since the phase of the signal at the PD input is synchronous with the phase of the reference voltage, an envelope signal of the input signal is generated at the PD output, which corresponds to the received information, which is filtered by a low-pass filter and is converted by a pulse shaper to a digital signal with TTL logic levels.

The clock frequency generator generates clock pulses from the reference frequency with a frequency equal to the information transfer speed in the channel (234 bit / s or 468 bit / s). The operating mode for speed is set from the computer through the control register RU.

The synchronization of the clock pulses of the receiver and the transmitter is carried out by the synchronization scheme for clock cycles CCT, where the phase of the clock frequency of the receiver is adjusted according to the fronts of individual input information packets. To eliminate the distortions present in the communication channel, the CCT provides information in the circular data register of the taxiway in the middle of a single package.

The SCS cyclic synchronization scheme determines the start time of the codogram by extracting the correction signal from the general information stream and provides the formation of code combinations for output to the RS-232C controller.

The limiters-pulse shapers provide normalization of the input pulses in amplitude in accordance with the signal levels of the TTL logic.

Quantity and sequence. the arrival of pulses depends on the course of the object.

The increment codes of the current X, Y coordinates formed in the block using reversible binary counters are issued to the computer via the RS-232C channel.
