The invention relates to telemechanics and is intended for use in multistage teleinformation systems with a large amount of information transmitted from lower monitored items (CP) through intermediate control points. (PU on the central points of the highest stage of dispatching.

The proposed device is intended primarily for use in telecom complexes of power systems.

Telemechanical complexes with a large information capacity are known, in which cyclic telemetry transmission (TI) and sporadic transmission of television signals (TS) are used, containing in the receiving devices of the lower stage units of information receiving units of the TS and TI, the output memory blocks of the converter, code - analogue of TI and information reproduction The TC, the retransmission control unit, and in the transmitters of the higher stage, the operating mode block and the information transmission block on the higher stage PU, connected to the output memory blocks of the transducer Atel code - similar PU lowest rung of trunk lines.

In these telecomplex retransmissions TI is carried out in code form: retransmitted values: Tx TI parameters are stored in the output memory blocks of the converter, the code of the lower stage F from 40 from there to the command from the operation mode block

the upper stage KP device selects a channel corresponding to the retransmitted TI parameter via a single code; as a result of the influence of the retransmission control unit, the selected channel information in the binary code is output to the trunk information buses from which the device’s transmission unit is transmitted

0 KP of the highest stage and further on the PU of the highest stage.

The vehicle information is retransmitted in a non-coded form: it is remembered by the output relays of the lower level PU playback information and is entered into the upper stage control device in a manner similar to the non-retranslated information from the local TC sensors.

This method of retransmitting a vehicle requires a large number of connecting wires between the contacts of the vehicle's relay output blocks of playback of PU lower-level devices and information inputs

5 device KP top level at the point of retransmission.

In addition, since the number of the retransmitted Ti channel is selected by a single code,

0, each T channel also requires its own interconnecting wire between the lower stage PUs of the highest stage fj.

The disadvantages of this device I are a large number of wires (lead connections), the need for individual output nodes of the G code transducers - ana pg for TI and for reproducing information for the TS) E lower stage PU devices for retransmitting teleinformation data in the event that if the reproduction of the teleinformation on the lower stage PU is not required. The closest to the present invention is a device for transmitting and receiving information, comprising, at a transmitting point (CP), a polling unit of tele-alarm sensors, a polling unit of tele-measuring sensors, a query block, pulse generator, the first output of which is connected to the distributor input, the first and second outputs the ports of which are connected respectively to the first inputs of the analog-to-digital converter and the converter of the parallel code to a serial output of which is connected to the input of the linear unit whose output is the output the transmitting point, the output of the telemetering sensor polling unit is connected to the second input of the analog digital converter, the retransmission signal output unit, the first output of which is connected to the second input of the parallel code to serial converter, the first inputs of the telemetric signaling and telemetering sensor polling units respectively, the first and second inputs of the transmitting point, as well as the distributor of channels and the pulse shaper, at the receiving point containing the linear unit the first and second outputs of which Connected respectively to the first input of the parallel code to serial converter and pulse generator, the first and second outputs of which are connected respectively to the input of the distributor and the second input of the parallel code to serial conversion bodies, the first output of which is connected to the first input of the first memory block, the output of the distributor is connected to the first input of the control unit, the input of the linear unit is the input of the receiving point, the OR element (assembly scheme), as well as the control, interrogation and cxeNW blocks or 2. In this device, the TC information is retransmitted in code form, similar to the retransmission of TI information. Due to this, there is no need for a large number of wires connecting the relays of the relay objects of the output block of information playback of the lower stage PU with the information inputs of the upper stage gearbox kit. However, the known device does not provide retransmission of the TS and TI in code form in the sporadic method of transmitting information of the TS. As is well known, the sporadic transmission method reduces the transmission time of information, which is of great importance when there are a large number of TS objects and several stages of retranslation. Therefore, one of the drawbacks of the prior art is the large transmission time of the retransmitted television signals. The purpose of the invention is to increase speed by reducing the transmission time of the retransmitted information in the sporadic method of transmitting the vehicle and simplifying the device by reducing the wired connections at the points of relay.

In FIG. 1 shows a block diagram of the device; in fig. 2 shows the structure of a control unit for a half-kit PU. The block diagram of the device (Fig. 1) contains two half sets of transmitting points of the lower stage (hereinafter, half sets of PU) and a half set of the controlled point of the highest level (hereafter, the half set of gearboxes). The practical number of half sets of PU may be greater. The amount of relayed information from all half sets of PU shall not exceed the information capacity of half gearbox. A device in a PU semi-kit (Fig. 2) contains a linear unit 1, a pulse generator 2, a distributor 3, a serial-to-parallel converter 4, a second memory block 5, an ORb element, a control unit 7, a first memory block 8, a converter 9 codes address TS and TI. The device also contains a bus for requesting retransmission information of the vehicle or TI 10 (one bus), resolution bus 11 (one bus) master informational buses 12 (8 buses), address buses 13 (7 buses) that connect the gearbox half higher stage and semi-PU sets lower stage. The gearbox kit (transmitting point) contains a polling unit of tele-signaling sensors (TC) 14, a comparison unit 15, a block of inputting retransmission signals 16, a channel 17 address driver of the TC 17, a query block 18, a telemetry sensor polling unit (TI) 19, an analog-to-digital converter 20 address generator channels TI 21, parallel code to serial converter 22, linear unit 23, pulse generator 24, distributor TOTOJx pulses 25. Control unit 7 contains element And 26, distributor 27, element NKHT And 28, element And 29. In semi-kit PU b ca. 8 has three types of input circuits include address, data and control inputs of the operation mode. The converter is made on the decoders. In the semi-complete set of gearboxes, blocks 14 and 19 contain input optocouplers for the vehicle, and input signals for the TI. The trunk information buses 12, the trunk buses of the vehicle addresses and the TI 13 are issued respectively to the combination of the binary information code and the address; The device works in the following way. The input of the linear unit 1 of the half-set PU is supplied with information from the lower KP in the form of address and information words, the TI information arriving cyclically, and the TS information sporadically as it is updated. Generator 2, whose frequency is corrected by the incoming pulse series from line unit 1, and valve 3, determine the switching times of the main units of the half-set. The address and information words from the linear block 1 are fed to the serial to parallel converter 4, from which the retransmitted information words are entered through the first inputs into the cells of block 8, the cell numbers of block 8 determine the adry words that are from the serial code converter to Parallel 4 comes to block 5, and the wake through the element OR 6 goes to the second inputs of block 8. In the half-kit, the pulse generator 24 provides two frequencies — high to the driver of the TC 17 channels and low (clock) to distribute 25. By the address determined by the shaper of addresses of the TC channels 17, the polling unit of the TC sensors polls the local sensors of the non-retransmitted TC objects of the given CP and the TC information of the polled channel as a code arriving at block 15, which is compared with the TC information recorded in the previous cycle polling if a new vehicle information is detected, it is inputted from block 14 into the parallel code converter into serial 22 and then into linear block 23. Distributor 25 controls the operation of the address generator of TI 21. After dny through the block polling TI sensor 19 inputs analog ve ranks from local sensors TI analog-digital converter 20, is converted .where govyh analogous variables in the code. The binary code enters the parallel code converter to serial 22 and, via the linear unit 23, to the communication channel for transmission to the upper stage control panel. Retransmission of TC and TI information is made at the request of the KP semi-complex. When retransmitting the vehicle information into a half set, the driver of the addresses of the channels of the vehicle 17 interrogates the state of the objects of the vehicle of the relay channels whose information is stored in block 8 of the half set of the control panel. In this case, the peTpaHcnHpyeNbix addresses of the TC channels in the form of a binary code appear alternately on the trunk buses 13. Since the Ho Kepa KP and PU retransmission channels, as a rule, do not coincide in the address code 9 converter, the conversion of the address code of the retransmitted channel of the KP half set into the address code of the retransmitted channel of the control panel of the PU, through element 6 or the second inputs block 8. Simultaneously with the appearance on the trunk buses 13 of the code of each address of the retransmitted TC channel, the request block 18 sends the 1 request to the second input of control unit 7 element 26, the first input of which receives a clock pulse At a certain cycle, the signal from the output of the element 26 removes the prohibition of the operation of the distributor 27 of block 7, which starts to work, and at certain positions in the presence of a request signal through the element 28 of block 7, signals are sent to the third inputs of block 8 These signals, in accordance with the received address of the channel of the vehicle from block 8, previously recorded information is output, which is fed to the trunk information of bus 12. At a certain position of the distributor 27 in the presence of a retransmission request signal at the element output nA AND 29 of block 7 a retransmission resolution signal appears, which enters the CPS semi-set via retransmission resolution bus 11. therefore, the retransmission resolution signal and the information word are sent to the retransmission signal input unit 16 via the TC channel defined by the driver addresses of the TC channels 17. As the TC information is transmitted sporadically, the information word must be transferred to block 15, where it is compared with the information word, recorded in the previous survey cycle, if the appearance of a new information tion TC that data word is overwritten from the block 16 to the transducer parallel to serial and 22 via line 23 enters the block Canas communication for transmission to the UE the highest stage. Thus, in the order of priority determined by the shaper of addresses of the TC 17 channels, the non-retransmitted TC informatis, respectively, from the polling unit of the TC 14 sensors and from the retransmission signal input block 16 is transmitted to the parallel code converter 29 pace of work palukomplekta KP. The operation of device blocks during TI retransmission is similar to their operation when retransmitting TS with

the difference is determined by the fact that the method of transmission of the TS is sporadic, and TI is cyclic.

The shaper of addresses of channels TI 21 of a semi-kit KP via trunk address buses 13 through the address code converter TC and TI 9 interrogates block 8 of a semi-kit PU, from which, upon request from block 18 via bus 10, control unit 7 issues a signal for outputting the information word TI to trunk information buses 12 and the retransmission resolution signal to the bus 11. The retransmission permission signal and the information word TI are written to the retransmission signal input unit 16, from where the information word TI enters the parallel converter Nogo code in serial 22 and through line unit 23 to the communication channel for transmission to the higher level PU.

Since the TC and TI retransmission information is produced on the same trunk information bus 1M, the main address buses are also common to the TS and TI, the retransmission information requests Tc and TI must be QjTb spaced apart

of time. For this, a ban on requesting and issuing the TC addresses by the driver of the TC channels 17 addresses is sent from the address generator TI 21 for the time of sending a request for TI retransmission information. “The shaper of addresses of TC channels 17 operates at high speed; therefore, stopping it will not lead to a significant delay in the transmission of information from the TC.

Thus, the introduction into the known device of the formers of the addresses of the TC and TI channels, the comparison unit in the gearbox half-block, the memory unit and the relay control unit in the half-kit PU allows the vehicle information to be retransmitted in a coded form with a sporadic method, which reduces the transmission time relay information of the vehicle,

The introduction of the trunk address busses to the converter of the codes of addresses of the TS and TI in the half-set of PUs made it possible to drastically reduce the number of connections between the half-sets of lower-order PUs and the upper-level control unit kit at the relay points.
