The invention relates to computer technology, in particular, to devices for exchanging information with an external device (for example, with a specialized computer) and for operational control of operational equipment of communication devices (channel, line, call station, measuring device), and can be used in automated communications. communication systems.

The purpose of the invention is to increase the reliability and expand the functionality of the device.

FIG. 1 is a block diagram of the device; in fig. 2 is a pulse generator circuit; in fig. 3 is a control block diagram.

The device (Fig. 1) contains a conjugation block 1, a first register 2 (receive register), a first decoder 3, a control block 4, a pulse generator 5, an operator panel 6, an alarm block 7, a parity block 8, a mode block 9, a block 10 commutation, second register 11 (transmit register), encoder 12 (instruction coder), second decoder 13, pulse former 14, shaper 15 parity bits, first trigger 16, second trigger 17, first And 18 element, second And 19, the third element And 20.

The control unit (Fig. 3) contains the first 28, second 29 and three; TI 30 triggers, the first 31 and second 32 control nodes.

The remote control device operates as follows.

The device can operate in the following modes: mode of receiving commands from a specialized computer (computer priority); transfer of command requests to a specialized computer initiated by the operator from the console; performance monitoring on itself (without disconnecting external communications from a specialized computer); switching control mode (cross device of communications equipment and test equipment).

The operation of the device in the mode of receiving commands from a specialized computer

performed as follows. one

From a specialized computer (not shown) to the input of the device (input of the 1 block mate) is supplied, for example, the control command Work enable (RR) command in the start-stop telegraph code (ASKOU II), through which information is exchanged between the device and a specialized computer. The PP command from the output of the conjugation block 1 through the mode block 9 enters the inputs of the receive register 2, the trigger 16, and the elements 18-20. From the register 2 in the parallel code, the command arrives at the inputs of the decoder 3 and the parity check block 8. Information from the output of the latter is compared with the incoming (from the output of block 9) parity bit in the AND 5 18 element. The trigger 17 is triggered in the event of a break in the communication circuits with the computer. At the same time, there is a discrepancy between the signals at the inputs of the element And 18 (due to

0

the presence of all zeros in the information, including the bit of parity).

When the start bit is received, the matching of signals is also compared, but by element 20. In the case of an incorrectly received start bit from element 20, a reset strobe is output to the reset input of trigger 16, the latter being reset.

When the information byte is correctly received by the AND 19 element, a write strobe is formed, arriving at the control input of the control unit 4. As a result, the information comes from the decoder 3 to the control unit 4, where the corresponding trigger of 28 to 30 is triggered. Corresponding command execution: the operation of one of the switching elements of the switching unit 10 includes the activation of the corresponding indication element in the alarm unit 7.

The operation of the device in the mode of transmitting command requests to a specialized computer at the initiative of the operator from the remote control unit is realized as follows.

On the operator console 6, the channel or line number is dialed (for testing or checking). The signal is fed to the input of the encoder 12, where a control command is generated in the start-stop telegraph form, in parallel code supplied to the register 11. Simultaneously (by shaper signals t4), a parity bit is generated in the 15-bit parity driver. The information recorded in the register 11 by a serial code through the block 9 of the mode When there is a logical O on the input connected to the console 6, is fed to the input of the interface 1 and transmitted through it to the communication channel. A control command is received from a communication channel by a specialized computer and recorded in its memory, after which a similar coyand confirmation from the specialized computer is sent to the device for remote control at the input of the conjugation unit. Further, the operation of the device is similar to that indicated in the previous case (in the mode of receiving commands from a specialized computer).

The operation of the device in the mode of monitoring the operability (on itself) of the receive and transmit chains and the registration of information inside the device is 5 as follows.

The transmission bus at the output of mode block 9 is switched from the output of the tree. 1 interface to the output of register 11 with the help of the operator 6 control panel. At the same time, O transmission bus from block 9 of the mode to. the conjugation unit 1 is turned off, and the transmission bus opens from mode unit 9 connected to the inputs of the receive register 2 and the trigger 16. In

5 of this case, from the operator’s console 6, the corresponding command is formed, encoded in the encoder 12, and then transmitted through the register 11 and the mode block 9 for

0 receive and write to register 2. Then, after decoding in the decoder 3 and checking the correctness of the received code (according to a command from the control unit 4), the corresponding commutation

 via the switching unit 10, the light signaling and the display in the signaling unit 7 are similar to the indicated one. Thus, the correctness of operation of almost all nodes of the receive-receive and record information circuits is verified, while the operability and correctness of the execution of commands is confirmed by an appropriate light signaling and display in the signaling unit 7.

The operation of the device in the switching control mode of any type of operational equipment of communication equipment (cross-over device, channel

0 or a communication line, etc.) is as follows.

When setting from the operator’s console 6 the number of the channel or communication line to be crossed or checked

(test), the transfer of the corresponding control commands (as indicated, see modes 2 and 3) to a specialized computer,

where they are formed. Then, the confirmation control command is received from a specialized computer. The received information is processed in a remote control device. In this case, the switching unit 10 of the corresponding contact group (not shown) is enabled. A channel or link is connected to the device. On

5-1

To the operator panel 6, the corresponding request command of the computer is formed; The transmitted information command request is stored in the computer. Further, the command-confirmation with a computer provides for switching in the switching unit 10 of the corresponding group of contacts that connect the corresponding elements of the console 6 (for example, a negotiation unit, a meter, etc.). The display of the number of the test channel of the line and the display of the state of the terminal devices of the operator console 6 is carried out on the signaling unit.

Thus, the proposed device due to the exclusion of

low reliability (due to the circuit design complexity of the teletype, punched tape junction box, punched tape readout unit, pen drive accumulator) and due to a more complete test of the device’s performance and JKOHT roll the presence of external circuits possesses greater reliability than the known ones. The device also allows direct exchange of information with a specialized computer.
