(5 ") ELECTRONIC KEY MORSE CODE

The invention relates to telegraph communication and can be used to semi-automatically form a beech of numbers and characters in the Morse telegraph code. According to the main author. St. No. 557505, the Morse code electronic key contains a generator, a driver consisting of a series of connected points matching blocks, points trigger, a dash matching block, a dash trigger and a collecting circuit, a two-way manipulator, and a feedback block consisting of collecting points patterns and a dash, a start-stop control unit consisting of successively connected sync pulse block, synchronization trigger and start-match block associated with the start-stop input of the generator and the first input of the block and sync coincidence S. However, in this way there is a loss of kompschnentov signs. The purpose of the invention is to eliminate the loss of character components. This goal is achieved by the fact that the electronic key of the Morse code, which contains a generator, a driver consisting of series-connected point match blocks, point trigger, dash match block, dash trigger and collective circuit, two-way manipulator, block connections, The starting point and dash collective schemes, the start-stop control unit, consisting of a series-connected sync pulse block, a synchronization trigger, and a start-stop coincidence block connected to the start-stop input of the generator and to the first input of the coincidence clock, introduced a locking assembly comprising a series-connected unit block matcher points, dots lock trigger block matcher dash lock and trigger lock

dash, the output of which is connected to the auxiliary input of the collecting circuit of the dash and to the first additional input of the collecting circuit of points, the output of which is connected to the input of the block of points blocking, the other input of which is connected to the auxiliary output of the synchronization trigger, and zero outputs of the trigger of points and the trigger of the dash are connected respectively to another input of the point blocking trigger and the dash blocking trigger, while the output of the point blocking trigger is connected to the second additional input of the collective point scheme, the input of which is connected to another input of the dash blocking block.

The drawing shows a structural electrical circuit of the proposed Morse code electronic key.

The electronic key of the Morse code contains a generator 1, a driver 2, consisting of serially connected blocks 3 points match, trigger 4 points, block 5 matches dash, trigger 6 dashes, collecting circuit 7. two-way manipulator 8, block 3 reverse link Zei, consisting of a collective scheme of 10 points and a dash and a collective Scheme of 1 dash, block 12 start-stop control, consisting of a serially connected block 13 of coincidence sync pulse, trigger 1 synchronization and start-stop block 15 coincidence, blocking node 16, The blocking point of the blocking points of the trigger 18, the blocking block 19 of the dash blocking trigger 20 and the blocking of the blocking dash block 20, one of the inputs of the block 17 of the blocking of the blocking points of points, is connected with the single output of the synchronization trigger 1 and the second one is collectively 10 point and dash circuits, output - to the installation input (R) of the point locking trigger 18, the other installation input (S) of which is connected to the zero point trigger output, and the output to one of the inputs of the dash blocking block 19. The other input of the block 19 coincidence block dash is connected to a two-way manipulator 8 (dash contact), and the output is connected to one setup input (R) of the dash lock trigger 20, the other setup input of which (S) is connected

with zero trigger output of 6 dashes, and the output of the dash blocking trigger 20 is connected to one of the inputs of the collecting circuit of 10 points and a dash and to one of the inputs of the collecting circuit of 11 dashes.

The key of the Morse code works as follows.

In the initial position (the manipulator 8 is in the middle position), the generator 1 is closed by a signal from the start-stop block 15 coincidence. On the steering outputs of trigger points k and 6 dashes, trigger points 18 and 20 of blocking points and blocking dashes, the state O is fixed, and at the zero output of trigger 1 of synchronization, state 1. At the outputs of the start-stop block 15, coincidences are present signal and, from its output, an opening signal arrives at the synchro-pulse block 13 and a locking signal (stop) at the controlled oscillator 1, as a result of which there are no signals at the output of the latter.

When the manipulator 8 is put into position, the control signal point is fed to the input of the collecting circuit of 10 points and a dash, from the output of which ... it will then go to the input of the 3 point matching block, to the input of the sync pulse block 13 and to the input of the blocking point 17 match . In this case, the signal from the output of block 13 matches for the installation. input (R) trigger 14 synchronization In the state in which at its zero output on vits zero signal.

At the output of the start-stop block 15 of coincidence, a zero state occurs, since at its inputs there will be no coincidence of signals. The locking signal disappears at the corresponding input of the synchronization pulse block 13. The generator 1 will begin to generate a sequence: the pulses that arrive through the block 3 of coincidence of points to the counting input of the trigger points and to the counting input of the synchronization trigger 14. The triggers of 4 and 14 points and synchronization will begin to switch in-phase in the pulse frequency division mode, i.e. on their outputs, a Wits pulse sequence of points.
