The output “blocking of the program launching node and blocking is connected to the input of the blocking code of the coding matrix, and the output of the starting node of the program launching and blocking is connected to the start input of the program node. The control output of the keyboard for telegraph dialing is simultaneously connected via the control input and the control output of the program node to the read control input of the intermediate memory node, and through the control input and output of the service signal forming node the end to the fourth control input of the summation node signals. The first control output of the program node is connected to the input of the advance signal generating node, the second control output of which is connected to the input of the service signal forming node.

The block diagram of the proposed set-coding device (NKU) is shown in the drawing.

The device includes a telegraph-typing keyboard 1, an encoding matrix 2, an intermediate memory node 3, a letter 4 node, a numeric character node 5, a program launch and blocking node 6, a program node 7, a letter 8 number combination registers, service signal generation node 9 "start, service signal generation node 10", progress signal generation node 11, information and service signal summing node 12, long-term memory node 13.

A set of messages is produced on the keyboard 1, made according to a typewriter keyboard. The keyboard allows you to make a set of Russian letters, numbers, punctuation marks and the "space character" and does not contain the letter and number register keys. The outputs 14 of the keyboard correspond to the case of letters, and the outputs 15 of the keyboard - the case of numbers. The "space" is included in the group of letters.

Before recruitment, the low-voltage switchgear is connected to a direct current network. When you press the corresponding key, the keyboard circuit produces a DC pulse of standard amplitude and duration. This impulse, depending on the case of letters or digits on inputs 14 or 15, is simultaneously applied to encoding matrix 2 and alphabetic node 4 or numeric characters node 5. In the encoding matrix, the code combination of the International Telegraph Code number 2 corresponds to a pulse coding matrix ( MTK-2), which is transfered by a parallel code to the inputs for writing characters to node 3, where it is recorded in the "memory. In the alphabetic node, the outputs 14, and in the numeric character node, the outputs 15 are combined, for example, by an OR circuit.

The impulse passed through node 4 or 5 simultaneously arrives at the program start and block 6 nodes, forming alphabetic and digital register code combinations 8, generating the service signal "start 9. Node 6 generates a pulse, which simultaneously arrives at the output" blocking on the encoding matrix 2 and blocks it from a false start and to the start input of the software node 7. The software node links the trigger pulse to the clock pulses and determines the sequence of writing operations in the "memory of the node 13 message and signaling. The instant of reference of the triggering pulse and the corresponding pulse of the clock frequency is the beginning of the time processes occurring in the program node.

The program defined by the software node is four pulses offset from each other by an interval of time determined by the advancement (change) rate of the memory of node 13. The first pulse of the program coincides with the start of the temporary work of the program. It starts simultaneously the node 8 of forming alphabetic and digital register code combinations and the advancing signal shaping node I. The node 11 generates a pulse that flows through the summation node of information and service signals 12 to one of the inputs of the long-term memory 13, providing advance (preparation) free memory cells for recording a mark. Node 8 generates a combination of alphabetic or numeric register. The development of either a letter or digital register by node 8 is determined by nodes 4 and 5: if the initial conditions of node 8 are determined by node 4, then node 8 generates an alphabetic register, and when defining initial conditions by node 5, a digital register is generated. In this case, the signals determining the initial conditions block the node 8 so that if after the letter the letter character is repeated, the node 8 does not re-give the register sign. Similar processes are carried out at node 8 with the recruitment of nodes of a certain number of numeric characters. During the time determined by the interval between the programmed pulses, the code combination of the register produced by node 8, with a parallel code, arrives at the summation node of information and service signals 12 and at the inputs of node 13, where it is recorded into a memory cell. Simultaneously with the register code combination from the output of node 9 through node 12, one of the inputs of node 13 receives and writes its cell "memory" signal "start of message" to B, and for all other characters of the message the signal "start does not repeat.

The second impulse of the program goes simultaneously to the Formation unit of the advancement signal I, which produces a pulse that prepares the next memory cell of the node 13 for recording the next character, and the control input is read by the intermediate memory node 3. The message sign is read from the outputs of the node 3 and through the node 12 by a parallel code enters the node 13, where it is written into a " memory cell.

The third pulse of the program performs the same functions as the first pulse. The repetition by the third impulse of the functions of the first increases the noise immunity of the telegraph radio link.

The fourth impulse of the program from the output of the signal "unlock node 7 goes to the start node of the program and block 6. Node 6 by means of the signal from output" block unlocks the coding matrix 2, preparing it to receive the next message sign.

When you press the next key on the message key 1 on the keyboard, the process of placing it in the memory of the node 13 is repeated. The difference here is that, in the absence of a register change, an entry into "we of the node 13 of the code combination of the register is not made, i.e. the first and third pulses of the program node 7 are not used. A non-lable character, “n-space”, used to separate words and groups of numbers in a message, is written into the “memory of node 13 in an alphabetic register, observing the rules for the formation and writing of alphabetic characters.

At the end of the set, the NKU is turned off. In this case, from the keyboard, a program node 7 and a node of the generated service signal "the end of the message 10" receive a pulse. This impulse triggers the program node, which organizes the promotion of the memory cell of the node 13 and simultaneously sends to the node 3 a command to read and write to the memory of the node 13 of the code pattern of the service signal the message section constantly underused in the individual cell of the node 3. Simultaneously With the issuance of a read command from node 3 (the CODE combination "section of the message from the second control output of the program node, node 10 receives a command to write to the" memory of node 13 signal "the end of the message, which through the node is summarized GOVERNMENTAL signaling and 12 flows into its intended cell "memory unit 13, where is recorded.

The proposed NKU, by using letter and digital register formation nodes, service signals, the beginning and end of each telegram, as well as the program node, allows you to automate the processes of register and service signal collection and write them to the long-term node, as well as automate the process of retrieving the required telegrams from the node of the long generic memory tp.
