Voltage converter 42 is a converter that, with an input voltage of + 24V from an external power source, absorbs ± 12V and + 5V at its outputs. Converter 42 provides + 12V power supply for circuits 37, 40, and 43, and + 5V supply voltage for all other circuits of control module 26 and communication module 24. In control module 26 of each set 6.0, 6.1, ОEPM 29 is connected by an 8-bit data bus with ROM 28, RAM 30 and BVV 35.

Consists of 16 keys representing a 4x4 matrix, of which 10 are digits , 4 - navigation keys, one confirmation of input and one key - reset.

OEVM 29 is connected to the EPROM 31 by a two-wire bus. EPROM 31 is intended to store the address of the control unit, a list of telecontrol commands, as well as a formalized description of the structure of the station.

UI 32 allows you to visually evaluate the operation of the module. To indicate the operating modes of the module, 3 LEDs are installed: green - “set active, yellow -“ set passive and red - “accident. Management of LEDs is carried out by OEVM 29.

Communication OEVM 29 with SLDS 37, as shown in the drawing of FIG. 2, is carried out by means of a communication line consisting of two wires (reception and transmission). The two OEVM 29 pins to which the USSL 37 connects are serial I / O ports and are configured (programmed) for universal asynchronous reception and transmission (USART). logical “O from OV to 0.4 V, logical level“ 1 from 2.4V to 5V) for the computer 29 when receiving, and vice versa during transmission. USLS 37 is based on RS-flip-flops (not shown in the drawings), and the pulse transformer, which is part of the USLN, galvanically decouples the unit from the internal local area network 25. In addition, the USLS 37 performs the function of protecting against network overloads. The temperature sensor (thermometer) (T) 38 is designed to measure temperature with an accuracy of 0.5 ° C and transmit the measured value to the OVM 29 via a 3-wire serial interface. The time counter ("Time Service) CB 39 is also connected to the OEVM 29 via a 3-wire serial interface and is designed to track time (hours, minutes and seconds) and the current date (year, month and day). The reset device (US) 33 resets the OVM 29 when the watchdog WDT timer, which is part of the US 33, is triggered after turning on the power or when the reset button is pressed. The UP 40 interface conversion device consists of a dual universal asynchronous transceiver (DUART) and RS-232 and RS-485 interface buffers (not shown in the drawings). The RS-232 buffer is intended for organizing communication between the control module 26 and the communication module 24 via P232 (43) of the module 24. The RS-485 buffer is necessary for organizing the exchange of information between the control module 26 of the main set 6.0 and the control module 26 of the backup set 6.1, as well as to organize the exchange of information between control module 26 of set 6.0 (or set 6.1 in case of failure of set 6.0) and the diagnostic module 6.2. Information exchange between module 26 and module 6.2 is carried out by bus 6.3. of set 6.0 is carried out as follows: ОЭВМ 29 of control module 26 of set 6.0 gives a signal to УУК 41, from which the signal via bus 6.3 goes to УУК 41 of the control module of set 6.1, which (УКК) turns off PN 42 of set 6.0 and injects a control signal to PN 42 converter set 6.1, upon receipt of which PN 42 supplies power to all units included in the set 6.1. In the communication module 24 of each set 6.0, 6.1, the OEWM 44 is connected by an 8-bit data bus with ROM 46 and RAM 45. The indication device UI 49 in the communication module consists of 7 LEDs that indicate the following signals and states: - state of relay K1 (transmitter on to the communication channel); state of relay K2 (inversion relay); issuing synchronization (INF); hardware control of the presence of a carrier (CD); message reception (PRM); message transfer (PRD); modem error (ERR). The P232 43 interface converter, as already noted above, is necessary for organizing communication between the OEVM 44 of the communication module 24 and the OEVM 29 of the control module 26 over the serial channel. The modulator (M) 50 converts the byte received on the parallel bus from the OEWM 44 into an analog signal of the V.29 protocol. From the output of the modulator, the signal is supplied to a matching device with a communication channel 52. A matching device with a communication channel (USKS) 52 is intended for matching signals with communication lines and consists of fuses, resistances, matching transformers, protective zener diodes and buffer operational amplifiers (not shown in the drawing ) 1 USKS 52 with its input-output through the switching device of the communication channels 53 is connected to the communication channel of the external local area network 2. The switching device of the communication channel (UKKS) 53 is intended for switching communication channels if it is necessary to organize an inversion or bypass. UKKS 53 is built on a relay. Relays are controlled by OEVM 44 outputs via ontrons. The received signal from external LAN 2 also passes through UKKS 53, USKS 52 and is supplied to demodulator 51. DM 51 performs the functions of converting the analog signal of protocol V.29 received from external LAN 2 into digital form and generating bytes from bits. For each received byte of information, an interrupt is generated in OVM 44. The interrupt request is removed after reading a pleasant byte of OVM 44 through the parallel bus. From the received bytes, the OEWM 44 generates a message that transmits to the control module 26 through the P-232 interface converter (43). In the communication module 24 OEVM 44 is connected to the PROM 47 two-wire bus. EPROM 47 is intended for storing the address of this control unit (5.1, 5.2, ..., 5.N), the transmission level, as well as the configuration of the communication line. The reset device (US) 48 is designed to reset the OEWM 44 by the control module 26 or when the watchdog WDT timer is included, which is part of the US 48 (not shown). In the diagnostic module 6.2, the voltage stabilizer CH 54 converts the +24 V voltage from an external power source through the K 55 switch. The CH 55 consists of two stabilizers at + 12V and + 5V. The voltage stabilizer 54 provides USLS 61 of the diagnostic module with a supply voltage of + 12V, and OEVM 57, PPZU 59, USLS 61, UI 58, UP 56 and US 62 of the diagnostic module 6.2 with a supply voltage of + 5V. The two OEVM 57 outputs to which the USSL 61 connects are serial I / O ports and are configured (programmed) for universal serial asynchronous receive-transmission (USART).

USLS 61 converts pulses with a duration of 2 μS, amplitude up to 12V, coming from the local network, into the TTL level for OEVM 57 when receiving, and vice versa during transmission. USLS 61 is made on the basis of RS-flip-flops, and the pulse transformer, which is part of USLS 61, galvanically decouples the unit from the local network (not shown in the drawing).

The output of USLS 61 is connected to two NMSh1 sockets (where the tested RKP-TS, RKP-TU blocks are installed).

OEVM 57 is connected to the PShU 59 two-wire bus. PISA 59 is designed to store the constants of an analog-to-digital converter (ADC).

UI 58 consists of 2 LEDs - indicating the presence of power and the performance of test functions.

The interface conversion unit UP 56 is designed to convert the serial interface to a parallel interface and consists of an RS-485 interface buffer through which the diagnostic module ОВМ 57 receives commands from the control modules 26 and controls the key K (55), which switches the supply voltage of the diagnostic module.

Upon receipt of the enable signal of the diagnostic module 6.2, UP 56 turns on the key K (55) and the supply voltage from an external source goes to SP 54 and MB 60, i.e. module 6.2 is activated.

When checking the RKP-TS block in the diagnostic mode of the OVM 57 of module 6.2, it controls the output matrix 60, which alternately supplies the voltage of the station battery (external power source) to all the inputs of the tested RKP-TS block. The test results are transferred to the 6.0 management module (or module 6.1, if module 6.0 is out of order). s In the diagnostic mode, when checking the RCP-TU unit, module 6.2 must check the correspondence of the output voltage value with each output of the RCP-TU unit to a predetermined minimum value at a given load. The role of the load and the matching of the amplitude of the signals of the RKP-TU output unit for measurement are performed by the matching device 62. The voltage is measured by the internal ADC of the OEVM 57. The measurement results of the OVM 57 are transmitted to the 6.0 control module (or 6.1 if the 6.0 module is out of order) via bus 6.3. View matrix 60, as shown in FIG. 11, contains nine keys (KC1, KS2, KSZ, KS4, KS5, KT1, KG2, KGZ, KG4) and twenty decoupling diodes (TC01, TC02, ..., TC20). The control inputs of nine keys (KS1, KS2, KSZ, KS4, KS5, KG1, KG2, KGZ, KG4) are supplied with control signals from the OVM 57 of the diagnostic module 6.2, while the control inputs of the keys are the input of the output matrix 60 to which the corresponding output is connected OEWM 57. From the output of the K 55 key, +24 V is supplied to the inputs of all nine keys, while the inputs of all nine keys are the input of the output matrix, to which power is supplied from the key of the diagnostic module. The output of the key KC1 is connected to the inputs of the first five decoupling diodes TC01, TC06, TC11, TC 16, the output of the second key KC2 is connected to the inputs of the following five decoupling diodes TC02, TC07, TC 12, TC 17, the output of the third key KSZ is connected to the inputs of the next five decoupling diodes ТСОЗ, ТС08, ТС13, ТС 18, the output of the fourth KC4 key is connected to the inputs of the following five decoupling diodes ТС04, ТС09, ТС 14, ТС 19, the output of the fifth key KС5 is connected to the inputs of the remaining five decoupling diodes ТС05, ТС 10, ТС 10, ТС 15, TC20.

Messages exchanged between the modules of the RCP-C 6 module satisfy the requirements of the IEC standard FT3 code format. This frame consists of the following components: the frame header and the frame body. The header is the initial code block of the frame, which includes the 24 field of the frame length L, the address field "A, the data management field" C, the data field and the control field. Field length L - usually contains one byte and indicates the number of bytes of data D in the information blocks of the frame. The value of L lies in the range from O to 255. Address field A, when transmitting a message from the transmitting station to the receiving one, contains the address of the receiving station. When transmitting a message, the answering station contains the address of this station. The number of bytes of the address field depends on the number of subscribers in the network. The address byte corresponding to the smallest number is transmitted first. The control field C contains information about the direction of the message and the functional purpose of the frame. The checksum field is generated using CRC-16 coding based on the generating polynomial: P (jc) x + x + x +; s + l; ° + x "+ x + x + x + 1 in accordance with GOST R IEC 870 -4-93. Information is transmitted sequentially in asynchronous mode. Transmission to the line begins with the least significant bit, i.e. DO D1 ... D6 D7. The transmitted byte begins with a start bit (transmitted by a logical zero), and ends with a stop bit (transmitted by a logical unit). The following messages are used in the protocol for exchanging the RCP-C block with the RCP-TS, RCP-TU and RCP-TI blocks on the internal local area network 25 of the distributed controlled point L1, KP2, ..., KPM: a) from RKP-Ts1: 1) Team - “Request for changes; 2) The command is “Status Request; 7.1, there is no 5) The command - “Give out voltage; 6) Team - “Get the number of the last included key and generator; 7) Command - “Request for settings; 8) Team - “Pre-programming; 9) Team - “Working programming; 10) Team - “Block restart, b) from RCP-TS: 1) Answer -“ Changes 2) Answer - “Information on changes; 3) The answer is “Information on the state of the block; 4) The answer is “Diagnostic information; 5) The answer is “The team has been accepted; 6) The answer is “Settings, c) from RCP-TU: 1) The answer is“ Changes 2) The answer is “Diagnostic information; 3) The answer is “The team has been accepted; 4) The answer is “The number of the last included key and generator; 5) The answer is “The team is running; 6) The answer is “Settings. Block RCP-C 6 sequentially sends the command "Request changes to all blocks of RCP-TS .2, ..., 7.N in order to detect changes in the state of controlled objects. If there are no changes from the last communication session, the block transmits a response - “Changes If 5 or less changes have occurred, then the block transmits a response that indicates: h new input status, one of the following:“ 10 - at the input logical level 1 ; "01 - at the input the logic level" 11 - at the input a flashing signal. If more than 5 changes have occurred, the block transmits a response with information on the status of all monitored signals, which indicates the current state of all inputs. After interrogating all RCP-TS 7.1, 7.2, ..., 7.N blocks, the RCP-C 6 block sends a status request to one RCP-TS block. Upon receipt of the request, the RCP-TS unit transmits a response with information about the status of all monitored signals. 1) Upon receipt by the RCP-TS unit of the message “Diagnostic request, the RCP-TS block will transmit a response with diagnostic information that contains: 1) fatal error information — the column number of output matrix 60 having: short circuit; breakage of diagnostic zero; break of the diagnostic unit. 2) information about non-fatal errors: checksum error counter; - counter of buffer overflow errors in reception and format mismatch; external restart counter OEVM 63 of the RCP-TS unit; OEPM restart counts 63 of the RCP-TS block from the internal watchdog timer. If fatal errors are detected on any request, the RCP-TS unit will respond with diagnostic information. To the request “Settings, the RCP-TS unit responds with a message that indicates: software version number; 27 h. Blocks received from the factory have address 254 (OxFE). To change the address of the block, it is necessary to reprogram the address of the block, which is carried out in two stages with the help of the commands “Pre-programming and“ Working programming. The “Pre-programming” command contains: a new block address; the date the address was set, for example, “11.12. address setting time, for example "07.45. Pa this command block RCP-TS (RCP-TU, RCP-TI) replies with the message "The command is accepted. Next, the RCP-C block sends a “Working Programming Command. Having received its RKP-TS unit (RKP-TU, RKP-TI), it responds with a message - “The command has been accepted, but with a new address. After polling all the RCP-TS blocks, the RUP-C block sends one change request message to the RCP-T block. Having received the request, the RCP-TU unit transmits a response - “There are no changes. Thus, the operability of the unit and the communication line is checked. After receiving the telecontrol command via communication line 2, the RCP-C block sends a command to the RCP-TU block "Turn on the key for 10 seconds, the RCP-TU block transmits a response" The command is accepted and turns on the key K1 131 (or K2 132), the number of which is indicated in teamwork. Next, the RCP-C unit sends a command “Issue voltage, which indicates: - the numbers of the activated outputs (it is possible to turn on all outputs simultaneously); team implementation time (from 40 ms to 10 s); Having received the command, the RCP-TU unit transmits the response “The command is accepted and carries out the output of voltage at the indicated terminals. After the time the command has been completed, the RyuT-Ts block sends a request “Issue the number of the last key and generator turned on, to this request the RKP-TU block transmits information about the key numbers (K1 131 or K2 132) that were turned on when the last command was executed and the numbers of outputs on which there was tension. com singing After 10 seconds from the moment the “Turn on the key” command is accepted, if the second signal does not follow the voltage, the K1 131 (or K2 132) key will be turned off, which eliminates false voltage on the outputs. When the control module 26 interacts with the communication module 24 of the 6.0 or 6.1 package, the following messages are used: 1) Messages transmitted from module 26 to module 24: -modem reset command; -query status byte; -the command for measuring the level of the input signal; -command to set the output signal level; - command to set the address of the MS; -the command to turn on the relay K1; -command turn on relay K1; -the command to turn on the relay K2; -the command to turn off the relay K2; -request of statistics of the N-th group. 2) Messages transmitted from module 24 to module 26: - readiness for reception; -the presence of the carrier frequency at the output of the transmitter; -the presence of the carrier frequency at the input of the receiver; - value of the measured input signal; - value of the set output signal level; Confirmation of the address setting command; -message about the current state of the relay; h h - Diagnostic module 6.2 works as follows. When checking the RKP-TS block, module 6.2 alternately connects the voltage of the station battery (external power supply) to all the inputs of the tested RKP-TS block. The test results are transmitted to the control module 26. When checking the RCP-TU unit, the module must verify that the output voltage value matches each block output to a predetermined minimum value. The voltage is measured by the internal ADC of the OEVM 57. The OVM 57 transmits the measurement results to the module 26. When the control module 26 interacts with the diagnostic module 6.2, the following messages are used: 1) Messages sent from module 26 to module 6.2: - Request for measurements; -Team to perform calibration; -The team switch to the testing mode of the RCP-TS blocks; -The team switch to the testing mode of RCP-TU blocks; -Set columns and rows of the matrix of the vehicle; Relay the message from the local RCP network; - Search for a module; -Perform automatic testing of RCP-TS; -Perform automatic testing of RCP-TU. 2) Messages sent from the diagnostic module 6.2 to the control module 26: -Result of measuring the voltage at the outputs of the RCP-TU; - The result of measuring the voltage of the station battery; -The command accepted is being executed; - The test result of the RCP-TS indicating the faulty input.

RKP-TU 8.1, 8.2, ..., 8.N blocks are intended for the implementation of telecontrol signals (activation of control relays) coming from Р1Ш-Ц via an internal local area network 25. Each of these blocks allows connecting 8 control relays. Communication with RKP-Ts 6 with RKP-TU 8.1, 8.2, ..., 8.N is carried out via the internal local area network 25, presented in the form of a PVC cable (shielded twisted pair cable). The principle of signal transmission in a local network, as mentioned above, bipolar pulse modulation (coding with a return to zero) pulses with a duration of 2 μS, an amplitude of up to 12V, pulse repetition rate of 28800.

The stabilizer (CH) 72 provides the conversion of voltage + 24 V from an external power source to a voltage of + 5Vi + 12V. SN 72 consists of two stabilizers + 12V and + 5V connected in series and provides USLS 74 with + 12V power supply, and OEVM 76, PPZU 73, USLS 74 and other elements of the R1Sh-TU unit, with the exception of filters, rectifiers and transformers, provides voltage of + 5V.

address and date of installation.

EGRO - ERG8 (87 - 96) are wide-mounted on optocouplers and are designed for galvanic isolation between OEVM 76 and energy converters PR1 - PR8 (99 - 102, 115 -118).

PP1, PP2 (77, 78) and TU1 - TU8 (79 - 86) allow you to control the power of the converters and the voltage at the outputs 1-8 of the RCP-TU unit, while the control information is read in a matrix way (similar to the method of reading in v, block RCP-TS, but without the control “O and“ 1). OutO outputs “1, and the result is read from INO, IN1. Converters PR1 - PR8 (99 - 102, 115 - 118) are controlled by OEVM 76 and generate pulses with an amplitude of 24V and a frequency of 40kHz. Converters are loaded on transformers T1-T8. Transformers T1 - T8 (103 - 106,119 - 122) are designed to realize "safe output, that is, the output voltage will be present only when the state of the elements of the HP1 - HP8 converter circuitry is in good condition (99 - 102.115 - 118). The rectifiers B1 - B8 (107 - PO, 123 - 126) provide AC rectification after the corresponding transformers T1 - T8 (103 - 106.119 - 122). Rectifiers are made according to the bridge circuit. Filters F1 - F8 (111 - 114, 127 - 130) smooth the voltage at the corresponding outputs of the first and second output modules and, accordingly, the outputs of the RCP-TU unit and suppress the conversion frequency. UI 75 consists of 3 LEDs - 2 green, indicating the reception and transmission of messages over the local network, and 1 red - to indicate the emergency status of the unit. UI 75 allows you to visually assess the operation of the unit when receiving and transmitting messages, when performing generation on each channel of the control unit, as well as in the event of emergency situations in the operation of the unit (the appearance of external interfering voltages at the outputs of the control unit and reading the address from the EPROM 73). USLS 74 is designed to coordinate the local network signals with OEVM 76 signals. Communication OVM 76 with USLM 74 is carried out through a communication line containing two wires (reception and transmission). The two OEVM 76 pins, to which the USLS 74 connects, are serial I / O ports and are configured (programmed) for universal serial asynchronous reception and transmission (USART). USLS 74 converts pulses with a duration of 2 μS and an amplitude of up to 12 V coming from the local network to the TTL level for OEVM 76 during reception, and vice versa during transmission. USLS is made on the basis of RS-flip-flops, and the pulse transformer, which is part of USLS 74, galvanically decouples the RKP-TU unit from the internal local area network 25. When the command is executed (using the example of voltage output 1 (output ТУ1) of the unit) ОЭВМ 76 Pulls UP1 signal to enable K1 131 of the first output module through the first EGRO galvanic isolation element (optocoupler). When the key K1 131 is activated, the voltage + 24V from the external power source is supplied to the input of the control device PP1 77 and to the input of the converter PR1 99. The voltage supply to the converter PR1 99 is controlled by OEVM 76 through the control device PP1 77. Next, OVM 76 starts to generate a sequence of control pulses with a frequency 40 kHz, which, through the second galvanic isolation element EGR1 88, are supplied to the PR1 99 converter. From the output of the PR1 99 converter, pulses of 24V amplitude are supplied to the transformer T1 103, from the output of which - shryamitel B1 107 assembled from a diode bridge circuit. From the output of the rectifier B1 107, the signals are fed to the input of the filter F1 111. In this utility model, each mentioned filter is made in the form of a smoothing capacitor. The output voltage from the output of the filter F1 111 goes to output 1 (output TU1) of the RCP-TU unit and to the input of the control element TU1 79, which opens when voltage appears on the output of the unit, and its opening, as already noted, is controlled by OEVM 76. Similar In this way, the voltage is output at the outputs 2-4 (outputs TU2 - TU4) of the unit. The pairing at the output of the block 2 and at the input of the control element TU2 80 appears when a signal is received from the second filter F2 112, to which the signal from the second rectifier B2 108 arrives, to the input of which the signal comes from the second transformer T2 104, the input of which receives the signal from the second Converter PR2 100, the inputs of which receive signals from the first key K1 131 and from the third galvanic isolation element EGR2

89. The voltage at the output of block 3 at the input of the control element TUZ 81 appears when a signal is received from the third filter ФЗ 113, to which the signal from the third rectifier ВЗ 109 is received, the input of which receives the signal from the third transformer ТЗ 105, the input of which receives a signal from the third converter PRZ 101, the inputs of which receive signals from the first key K1 131 and from the fourth galvanic isolation element EGRZ 90. The voltage at the output of the 4th unit and the input of the control element TU4 82 appears when a signal is received from the fourth filter Ф4 114, the input of which receives the signal from the fourth rectifier B4 software, the input of which receives the signal from the fourth transformer T4 106, the input of which receives the signal from the fourth converter НР4 102, the inputs of which receive signals from the first key К1 131 and from the fifth element galvanic isolation EGR4 91.

In exactly the same way, the second output module 98 of the RKP-TU block is operated and the signals appear at the corresponding inputs of the corresponding control devices TUZ - TU8 (83, 84, 85, 86) and at outputs 5-8 (TU5 - TU8) of the RKP-TU block . At the same time, the signals at the outputs of the converter blocks НР5 - ПР8 (115-118) appear when the second key K2 132 is triggered and the signals from the corresponding outputs of the galvanic isolation elements EGR5 - EGR8 (92 - 96) are received. In addition, the converter PP2 78 from the second key K2 132 also receives + 24V voltage from an external power source.

In this utility model, PP1 77 and PP2 78 are optocouplers.

If the switch K1 131 is turned on and the voltage + 24V is present on the PR1-PR4 converters (99 - 102), then the optocoupler in PN1 77 is open. Logical "1 with outO through the open optocoupler falls into INO (if there is no voltage on the PR1-PR4 converters (99 - 102), then the optocoupler is closed and INO" О). Replaceable columns every 40 ms, i.e. after 40 ms, the output “outl” rises “1, and the remaining out“ О. If there is voltage at the output of TU1, then the optocoupler is open and also “1 s outl goes to INO. If closed (no voltage), then INO “O.

Let us now consider the operation algorithm of the signal output unit RCP-TU. 1. The reaction of the RCP-TU to "hanging of the microprocessor OEVM 76.

Hanging in this utility model is understood as follows. “Hanging in the sense of stopping the change of the command counter, while the outputs remain a certain combination of“ O and “1, and the absence of changes at the input of the transformer will lead to generation of generation. "Hangs in the sense of uncontrolled" looping when executing a separate section of program code.

“Looping is possible only when performing a cyclic section of the program in the following cases:

non-execution of the increase / decrease commands of the current counter during the execution of the cycle;

transforming a conditional transition team into an unconditional;

when the cycle boundary is reached, completion signs are not set (flags: C sign of overflow, Z - sign of zero).

When implementing the RKP-TU program code, the principle of replacing the cyclic sections of the program with linear ones is applied, due to the repeated repetition of the codes executed in the cycle. To reduce the length of the program code, a subroutine call mechanism is used. In this case, to ensure control over the duration of pulse generation at the input of the converter, a calculated input to the linear section consisting of only CALL commands is used.

The microcontrollers of the PIC16C6X family have a built-in WDT watchdog timer, which can only be turned off via the configuration bit set during programming. To increase reliability, it works from its own RC-generator. Using WDT allows you to control the correct implementation of the algorithm. In the event of any violation, the “WDT replenishment stops, which leads to a hardware restart of the OEVM 76. The circuitry of the RCP-TU unit provides continuous control of the voltage at the unit outputs. If a voltage appears at the output of the unit, then this voltage will be fixed by OEVM 76 and a message will be sent indicating the presence of voltage. The unit does not execute commands, but only responds to a diagnostic request and must be replaced by a working one. 2. The reaction of the RCP-TU to the violation of the exchange protocol with RCP-C 6. The exchange protocol uses asynchronous (start-stop) transmission of bytes with a header of 2 bytes (0x05 and 0x64) and CRC16 with a code distance. The presence of the “start and stop” bits in each received byte is controlled by hardware. Violations of the protocol: the command of the command for supplying voltage to the converter is incomplete; incomplete sending command to start the converter: the presence of distortions in the message. If the message “lose the switch on the output of the voltage block will not be because no voltage will be supplied to the converters and the command will not be accepted for execution, a response will be given by the diagnostics about the key not turned on. If the message is lost, “there will be no voltage generation at the output of the voltage block. there will be no control action on the generators, the voltage from the converters will be removed after 10 s. Using CRC16 with allows you to guarantee the detection of almost any errors in the received message. Only messages for which the received and calculated CRC-16 are the same are accepted for implementation. 3. The reaction of the RCP-TU when a failure is detected.

- uncontrolled operation or inability to control the key to supply voltage to the converter;

-control of the code displayed on the outputs of the block recorded in 4 different places of RAM OEVM 76 in different formats.

The detection of any failure in the RCP-TU block prohibits the execution of the command to turn on the keys and control generation at the input of the converter.

4. Execution of the generation command (see Fig. 5).

RCP-C 6 does not betray RCP-TU two teams. The first preliminary - the converter is supplied with power, the second working one - sets the generation time and sets at which outputs to give voltage. Having received a preliminary command, OEVM 76 starts the timer for 10 seconds. After time, if a working command does not come, the supply voltage of the converters will be removed.

Upon receipt of the RKP-TU working command (see Fig. 5), in which the block address, CRC16 0, the block type and the command type coincide, ОЭВМ 76 rewrites from the message the code of the necessary channels for generation (at which terminals to generate voltage) in the RAM ОЭВМ 76. Cells KO, K1, K2, KZ are highlighted at four different points in RAM OEVM 76 (see tab. 1).

In the cell KO is written the code of the numbers of the generators that increase the voltage (KO). IN

the inverted value of KO with the rearranged tetrads (K3 SWAP (KO)) is written.

After writing to the cells KO, K1, K2 n KZ, set the flag of the generation command and program the necessary channels OEVM 76 for output. In accordance with the required generation time, the table is shifted by the corresponding value, which

The final address determines the number of routines. After successfully working out the algorithm for issuing stresses, we clear the flag of the generation command, turn off the power of the converter, program OEVM channels 76 for input, and exit the program. 4. Subroutine 10 millisecond meander generation (see Fig. 6). When entering the subroutine, it is checked: whether the generation command flag is set, whether there is control of the power supply of the converters, the absence of voltage at unused outputs and the coincidence of the position code ((SWAP (KO) 0K3) + (K2-SWAP (K1)) 0) of generation in four different points RAM OEVM 76 (see Fig. 6). If all four conditions are met, 450 elementary meander generation packets are executed. If at least one of the four conditions is not fulfilled: the flag of the generation command is reset, the power to the converter is turned off, and the OVM 76 input channels are programmed. Before exiting the subroutine, the WDT is energized. 5. An elementary meander generation package (see Fig. 7) When entering the subroutine (see Fig. 7), all conditions are checked: 1). There is no voltage at unused outputs; 2). There is power control of converters; 3). The positional code of the channels for generation at four points of RAM matches. If at least one of the three conditions is not fulfilled, the generation command flag is reset and the power to the converters is turned off. If all conditions are fulfilled, we fulfill 1/2 of the generation period and enter the necessary channels О, fulfill Л of the generation period in the necessary channels 1.

The RKP-TS 7.1, 7.2, ..., 7.N remote signaling signal input signal blocks in each controlled point KP1, KP2, ..., KPM are designed to enter controlled signals and transmit them to the RCP-Ts of the corresponding controlled point over the internal local network 25. RKPTS block allows you to control twenty input signals with an amplitude of 24V DC or AC voltage. The communication of blocks 7.1, 7.2, ..., 7.N in each distributed controlled point KP1, KP2, ..., KEN with RCP-C is carried out via the PWS cable (shielded twisted pair). The principle of signal transmission in the internal LAN is bipolar pulse modulation (coding with a return to zero) - pulses of 2 μS duration, amplitude up to 12V, pulse repetition rate of 28800.

As can be seen from the drawing of FIG. 3, each RCP-TS unit contains a control module 68 and an input module 69.

The control module 68 contains a voltage stabilizer 66 (SI), a serial flash programmable read-only memory 64 (EPROM), a single-chip electronic computer 63 (OEWM), an indication device 67 (UI), and a device for matching with a local area network 65 (USL).

The voltage stabilizer 66 converts + 24 V voltage from an external power source to + 5 V and + 24 V. The voltage stabilizer 66 consists of two stabilizers + 12 V and + 5 V connected in series and provides the USL 65 with a + 12 V power supply, and an OEWM 63, ППЗУ 64, УСЛС 65 and УИ 67 with supply voltage + 5V.

OEVM 63 implements the following functions:

receiving messages from the internal LAN 25;

and the transmission of messages on the status of the inputs of the vehicle to the internal local area network 25;

a health check (diagnostics) of input module 69 (test readings of zeros and ones);

USLS 65 is designed to coordinate the signals of the internal local area network 25 with the signals of the OEVM 63.

EPROM 64 is used to store the device address, date and time of programming. Data is exchanged over the bus.

UI 67 allows you to visually evaluate the operation of the R1Sh-TS block when receiving and transmitting messages, as well as in the event of emergency situations in the operation of the RCP-TS block (errors in the diagnosis of input module 69, reading the address from EPROM 64).

Input module 69 of each RCP-TS block is made in the form of a matrix of size m x t, where, consisting of six columns (TO - T5) and six rows (10 -15).

The matrix consists of galvanic isolation elements (70.1, 70.2, ..., 70.20) and elements

OVM input-output integrity control (71.1, 71.2, ..., 71.16). The number of elements for monitoring the integrity of the inputs and outputs of the computer is less than the number of elements for galvanic isolation. In the particular case of execution in the input module, as shown in the drawing of FIG. 3, there may be 20 elements of galvanic isolation (TC1, TC2, ..., TC20) and 16 elements of integrity control of the I / O of the computer.

TC1, ..., TC20 are implemented on optocouplers and carry out galvanic isolation of input circuits. Secondary optocoupler circuits are assembled according to the matrix input scheme.

Elements 70.1, ..., 70.20 and 71.1, ..., 71.16 are located in the matrix so that they form a row of rows and a column of columns of the matrix.

As can be seen from the drawing of FIG. 3, in the first column of the matrix TO contains three elements of galvanic isolation TC1, TC2, TSZ (70.1, 70.2, 70.3) and three elements of integrity control (71.1, 71.2, 71.3), in the second column T1 of the matrix contains three elements of galvanic isolation TC4, TSZ , ТС6 (70.4, 70.5, 70.6) and three elements of integrity control (71.4, 71.5, 71.6), the third column Т2 of the matrix contains four galvanic isolation elements ТС7, ТС8, ТС9, ТС10 (70.7, 70.8, 70.9, 70.10) and two integrity control element (71.7, 71.8), the fourth column of the TK matrix contains four galvanic isolation elements TSI, TS 12, T 13, TC14 (70.11, 70.12, 70.13, 70.14) and two integrity control elements (71.9, 71.10), the fifth column T4 of the matrix contains three galvanic isolation elements ТС15, ТС 16, ТС 17 (70.15, 70.16, 70.17) and three elements integrity control (71.11, 71.12, 71.13), the sixth column of the matrix T5 contains three galvanic isolation elements TC18, TC18, TC20 (70.18, 70.19, 70.20) and three integrity control elements (71.14, 71.15, 71.16). As can be seen from the drawing of FIG. 3, in the nerve row 10 of the matrix, the elements are located in the following sequence: 71.1, 70.4, 70.7, 70.11, 70.15, 71.14, in the second row of the II matrix, the elements are in the following sequence: 70.1, 71.4, 70.8, 70.12, 71.11, 70.18, in the third row 12 of the matrix contains the elements in the following sequence: 70.2, 70.5, 71.7, 71.9, 70.16, 70.19, in the fourth row 13 of the matrix there are elements in the following sequence: 71.2, 71.5, 71.8, 71.10, 71.12, 71.15, in the fifth row 14 of the matrix are located elements in the following sequence: 70.3,71.6, 70.9, 70.13, 71.13, 70.20, in the sixth 15 row of the matrix is located wife elements in the following sequence: 71.3, 70.6, 70.10, 70.14, 70.17, 71.16. OEVM 63 configures six lines of TO-T5 columns for output, and six lines of lines 10-15 for input. At the intersections of columns and rows are monitored signals (TC1 - TC20) and diagnostic signals "O and" 1 (diagnostic zeros and ones). Columns are scanned sequentially by establishing a logical “1 on the column lines (TO - T5) and determining the level on the line lines (10 -15). The scan time of each column is 20 mS., And the entire matrix - 120 mS. When scanning each column, the diagnostic signals “O and“ 1 are checked, which guarantees the operability of the input matrix (OEVM inputs respond to “O and“ 1). For example: when reading the signals of the line of the TO column, the OEVM 63 sets the logical “1 (+ 5V) on the line to the TO column, and on the lines of the T1-T5 columns the logical“ O (OB) and reads the state of the lines of lines 10-15. At the same time, OEVM 63 checks the control “O and“ 1, i.e. 10 "1, and 13 15" O. And besides this, OEVM 63 checks the information signals themselves (TS1-TSZ). If

At the TCI input there is a voltage of 24V, the optocoupler is open and the logic level “1 passes from TO to line line II (signal on line line AND“ 1). If the voltage at the input of TC1 is equal to OV, then the optocoupler is closed and the logic level “1 does not pass from TO to line line II (signal on line line II“ O). It is also carried out for other signals of the TO column line (TC2, TSZ).

OEVM 63 is connected to the EPROM 64 by a two-wire bus. When starting up, OEVM 63 reads the block address, the date and time of programming. If necessary, OEVM 63 writes to the EEPROM 64 the new address and installation date.

UI 67 consists of 3 LEDs: 2 green, indicating the reception and transmission of messages over the local network, and 1 red to indicate the emergency status of the unit.

Communication OEVM 63 with USLS 65 is carried out using a connection line containing two wires (reception and transmission) (in the drawing of Fig. 3, these two wires are also combined in one line). The two OEVM 63 pins to which the USSL 65 is connected are serial I / O ports and are configured (programmed) for universal serial asynchronous reception and transmission (US ART).

USLS 65 converts pulses with a duration of 2 μS and an amplitude of up to 12 V coming from the local network to the TTL level for OEVM 63 during reception and vice versa during transmission.

USLS 65 is based on RS-flip-flops, and the pulse transformer, which is part of the USLS 65, galvanically isolates the RKP-TS unit from the internal LAN 25.

The RCP-TS unit works according to an algorithm consisting of a main cycle and two routines called by time interruptions.

The main cycle is as follows (Fig. 8).

In this cycle, the correct operation of the RCP-TS unit is checked by monitoring the passage at the control points, for which the WDT watchdog timer is used, the replenishment of which is stopped in case of violation of the passage of the command counter at the control points. In the main cycle, the OEVM 63 "energizes the WDT watchdog and increases

cycle counter. The cycle counter is cleared in interruptions when receiving messages and when polling the input module matrix 69 (control points). If the cycle counter is not reset (the functioning algorithm of the unit is violated), then when the cycle counter is increased to a certain value (the count is approximately within one minute), the WDT refueling stops, which leads to a hardware restart of the OEVM 63. This ensures that the algorithm is implemented correctly and, in case of violation, approximately after 1 minute, the OEWM 63 will restart.

When scanning the matrix of input module 69, diagnostic readings “О and“ 1 are made, in the event of a failure (instead of “О read“ 1 or vice versa “1 read“ О), all TS signals located in the column and row are blocked (set to an undefined state) An error has been detected.

Then the presence of changes is determined and the blinking mode of the vehicle input signals is monitored. These routines are discussed later.

If there is an input message from RCP-C (i.e., access to the unit), a response is generated depending on the type of request and transmitted to the internal local area network.

Change definition cycle. The determination of changes in the input signals of the vehicle is carried out in the interrupt. Interruptions follow every 2.5 ms. Processing of one group of 20 ms. Each input signal of the vehicle is monitored 8 times during the processing period of the group. The input signal of the vehicle is taken as "1 if out of the 8 read input states at least 3 are equal to" 1 (for 50 Hz AC signals). The current state is compared with the previous one and with a difference, a flag is set to change the input of the vehicle for processing in the main cycle.

In the Definition of Changes subroutine (Fig. 9), which is called from the main loop, the presence of the change flag is checked (there is a change in the state of the TS input). If there are no changes, then the routine exits. If there is a change, then the TC input change flag set in the pre-switch is reset, and then the TC input change counter (COUNT TC) is further increased. The counter is reset in the blink detection routine once every 4 seconds. If the change is not the first (COUNT TC 9 1 counter) or the signal blinking flag is set, exit the program, but provided that COUNT TC 1 and the TC signal is not flashing, the health of the vehicle matrix is checked. With a working matrix of the vehicle, i.e. this vehicle input is not blocked, the flag is set to transmit the change of the vehicle input. It is believed that there has been a change in the input of the vehicle and upon request for changes it will be transmitted to the RCP-C. If the input module 69 matrix is faulty, the change will not be transmitted. Next, the state of the vehicle input is determined by a two-bit code (the state of the vehicle can be: undefined - the input is blocked - 00, the state is "O - 01, the state is" 1 - 10, the blinking state is -11) and the exit from the subroutine. The blink detection cycle (see FIG. 10). The blink detection routine is called once every 4 seconds. The blinking period is 1.5 seconds (40 blinks per minute). With this interval of the change count and the blinking period, at least 5 changes in the state of the input signal of the vehicle will be guaranteed. Therefore, with a steady blinking of the input signal, the COUNT TC counter in each blink detection cycle will have a value of 5. The algorithm branches are implemented for cases: the beginning of the blinking mode of the input signal of the vehicle fell into the 4 second interval, or its completion. Or failed situations, bounce of contacts, false positives from interference. Consider the structure and operation of the blocks R1SP-D. RKP-D blocks 133.1, 133.2 are designed to collect information from the Disk-B system (information is taken from the interface of the Disk-B equipment, the Disk-B equipment is used to detect overheated axle boxes in the composition) and transfer it to the RCP-C via a local network . The unit also provides input of discrete signals “Alarm, implements the command“ Reset Alarm. Each of these blocks allows you to connect to one Disk-B system (usually 2 systems are installed at stations - on both sides of the station). Communication RKP-Ts 6 with RKP-D 133.1, 133.2 is carried out on the internal local area network 25, presented in the form of a cable PPS (shielded twisted pair). The principle of signal transmission in a local network, as already mentioned by Qj (l. V, above, bipolar pulse modulation (coding with return to zero) - pulses of 2 μS duration, amplitude up to 12V, pulse repetition rate of 28800. The RCP-D unit, as shown in the drawing of Fig. 12, the following elements are included: a voltage converter (PN) 138, a serial reprogrammable read-only memory device (EPROM) 136, a device for matching with a local area network (USLS) 137, an indication device (UI) 139, a single-chip electronic computer machine (OEWM) 135, the first galvanic isolation element (EGR1) 140, the second galvanic isolation element (EGR2) 141, the third galvanic isolation element (EGRZ) 142, the FIFO buffer (FIFO BUF) 143, the linking element with the Disk- “B” interface . (SI) 144. The PN 138 voltage converter provides the supply voltage (+ 12V) of the USSL and the voltage of + 5V to PPZU 136, USSL 137, UI 139, OEVM 135, EGR1 140, EGR2 141, EGRZ 142, BUF FIFO 143, SI 144 . Power is supplied to the voltage converter from an external power source. PN 138 consists of a converter from + 5V to + 12V. OEVM 135 implements the following functions: and receiving messages from the internal local network; transmission of messages with the results of information received from Disk- “B to the internal local network; signal input “Alarm, implementation of the command“ Reset Alarm; Writing and reading addresses from EEPROM 136; health check (diagnostics); and the formation and transmission of diagnostic messages. EPROM 136 is used to store the device address, date and time of programming. OEVM 135 is connected to EEPROM 136 via a two-wire I C bus. At startup, OEVM 135 reads the block address, date and time of programming. If necessary, OEVM 135 writes to the EEPROM 136 a new address and installation date. v EGR1 - ERGZ (140 - 142) are made on optocouplers and are designed for galvanic isolation between the OEVM 135 and external circuits. EGR1 140 provides galvanic isolation when the signal “Alarm. EGR2 provides galvanic isolation when the signal “Alarm2. EGRZ provides galvanic isolation during the implementation of the command (signal output) "Alarm Reset. UI 139 allows you to visually assess the operation of the unit, consists of 7 LEDs. 2 green ("PRM," PRD) LEDs indicate receiving and transmitting messages on the local network. 1 red (“ERROR error”) LED is intended to indicate when an emergency occurs in the operation of the unit and when errors are detected. 2 red LEDs indicate the status of the “Alarm. 1 green LED (“NC no comments) lights up during normal operation of the unit. 1 red LED “RECORD” is intended to indicate the presence of a train in the control section and to wait for information from the Disk- “B. USLS 137 is designed to coordinate the local network signals with OEVM 135 signals. Communication OVM 135 with USLM 137 is carried out through a communication line containing two wires (reception and transmission). The two OEVM 135 pins to which the USSL 137 connects are serial I / O ports and are configured (programmed) for universal serial asynchronous reception and transmission (US ART). USLS 137 converts pulses with a duration of 2 μS and an amplitude of up to 12 V, coming from the local network, into the TTL level for the OEVM 135 during reception, and vice versa during transmission. USLS is based on RS-flip-flops, and the pulse transformer, which is part of USLS 137, galvanically decouples the RKP-D unit from the internal local area network 25. The FIFO 143 BUF FIFO buffer records a data packet from the interface of the system (equipment) Disk- “B of output na high speed. Reading this data from the FIFO buffer and further processing is performed by the OEVM 135. Let us consider the structure and operation of the RCP-PI block. The block of interface converters RKP-PI 134 is designed to organize the exchange of information of devices with a standard serial communication interface and RKP-C 6 but a local area network 25. The unit allows you to connect devices with RS232, RS485, RS422 interfaces. Each of these units allows you to connect to one adjacent system of monitoring and diagnostics of AT devices (automation and telemechanics) and provides the conversion of messages of these systems into message formats used in the internal local network 25. Communication of RCP-C 6 with RCP-PI 134 is carried out via the internal local network 25, presented in the form of a cable PVC (shielded twisted pair). The principle of signal transmission in a local network, as already mentioned, bipolar pulse modulation (coding with return to zero) - pulses with a duration of 2 μs, an amplitude of up to 12 V, pulse repetition rate of 28800. As part of the RCP-PI 134 block, as shown in the drawing of FIG. . 13 includes the following elements: a voltage stabilizer 148 (SP), a serial reprogrammable read-only memory device (PRZU) 146, a device for matching with a local area network (USLS) 147, an indication device (UI) 149, a single-chip electronic computer (OVM) 145, interface converter RS232 (P232) 150, converter RS485 (П485) 151, converter RS422 (П422) 152. Voltage regulator 148 converts + 24 V from an external power source to + 5V and + 24V. The stabilizer 148 consists of two stabilizers on + 12V and + 5V connected in series and provides USLS 147 with a supply voltage of + 12V, and OEVM 145, PPZU 146, USLS 147, P232 150, P485 151, P422 152 and UI 149 with a supply voltage of + 5V .

The ROM 146 is used to store the device address, date and time of programming. OEVM 145 is connected to EEPROM 146 by a two-wire bus. At start-up, OEVM 145 reads the address of the block, the date and time of programming. If necessary, OEVM 145 writes to the ROM 146 a new address and installation date.

And 149 allows you to visually assess the operation of the unit, consists of LEDs: 2 green indicate the reception and transmission of messages over the local network 25; 1 red to indicate the occurrence of emergency situations in the unit; 2 green - indicate the reception and transmission of messages occurring at any of the joints.

USLS 147 is designed to coordinate the local network signals with OEVM 145 signals. Communication OVM 145 with USLM 147 is carried out by means of a communication line containing two wires (reception and transmission). The two OEVM 145 pins, to which the USSL 147 connects, are serial input-output ports and are configured (programmed) for universal serial asynchronous reception and transmission (US ART). USLS 147 converts pulses with a duration of 2 μS and an amplitude of up to 12 V, coming from the local network, to the TTL level for OEVM 145 when receiving, and vice versa during transmission. USLS is based on RS-flip-flops, and the pulse transformer, which is part of USLS 147, galvanically isolates the RCP-PI unit from the internal LAN 25.

OEVM 145 has another universal serial asynchronous transceiver (USART), which is used to work with interface converters. Involved, to connect to an adjacent system for monitoring and diagnosing AT devices (automation and telemechanics), there can be only one interface converter (such as the adjacent system has), and the remaining interface converters are simply not used
