Abstract

The invention relates to automation and computing and can be used to enter information into the interface equipment with a communication channel. The purpose of the invention is to expand the scope of application due to the organization of additional input modes. The goal is achieved by the fact that the device has an AND-HE element 6, a register 9, two triggers 10, 11, which allow you to create an information input mode, in which (when a certain group of switching elements is pressed) the generator 8 of a single pulse with an interruption produces pulses provide multiple input of the same information. 9 il.

The invention relates to automation and computing and can be used to enter information into the interface equipment with a communication channel.

The aim of the invention is to expand the scope by organizing additional input modes.

FIG. 1 is a block diagram of a device for inputting information; FIG. 2 shows an example of a specific implementation of a device decoder for inputting information; FIG. in fig. 3 shows an example of a keyboard; in fig. 4 is a diagram of a single pulse generator in FIG. 5- time diagram of the operation of the pulse generator., The counter and the first decoder; in fig. 6-8 is a temporary diagram of the operation of the counter in FIG. 9; a temporary diagram of the operation of the counter and the third decoder.

The information input device contains a pulse generator 1, counters 2j decoder 3, a keyboard (block 4 j element AND 5, element AND-H 6, element NOT 7, generator 8 of a single pulse, register 9, first and second triggers 10 and 11. Decoder 3 contains the first, second and third decoders 12,13 and 14, the element And 1 positions 16-50 marked the outputs and

the inputs of the device blocks. I

Keyboard 4 contains a counter 51 decoder 52, a block 53 of switching elements and a multiplexer 54.. Positions 55 to 62 denote the inputs of the keyboard nodes.

The generator 8 of a single pulse contains a counter 63, a decoder 64, triggers 65 and 66, and element 67.

The device works as follows.

The counter 2 under the influence of impulses at the output 16 of the generator 1 continuously operates causing the continuous operation of the decoders 12, 13 and 14. At the beginning of the pulse at the output 38 of the decoder 14. The element 15 produces a pulse to reset the counter 51 in block 4, ensuring its synchronous operation with the counter 2 with the outputs 19-26, while the counter 51 in the block 4 operates under the influence of pulses at the output 18 of the counter 2, Before pressing any switching element of the keyboard in the block 4, the generator 8 is in

8 2

the initial state, its counter 63 and triggers 65 and 66 are set to state O. When any switching element of the block is pressed

53 switching elements at output 42 of block 4 appear signals at times at which the code at the output of counter 51 of block 4, and hence at outputs 19-26 of counter 2, reaches the value given to the code of the number of the pressed switching element. The signal to the output 42 of block 4 passes from the corresponding output of the decoder 52 through the corresponding contact of the switching element of the block 53 of switching elements and through the corresponding input of multiplexer 54 of block 4. The output from the output 42 of block 4 passes through the element 5 to the counting input of the counter

in the generator; 8 is a single pulse, but switches it only at the moment of action of the pulse at the output 39 of the decoder 14. The generator 8 of the single-25 pulse produces only one pulse at the output 46, which produces the code set at the outputs 19-26 of the counter 2 and corresponding to the number of the pressed switching element, into register 9. At the same time, one of the triggers 10,11 will be set to 1. The signal at output 37 of the decoder 13 permits only trigger 10 to be set to 1,

35 and in the absence of a signal at output 37, only trigger 11 is set to 1. The code at outputs 19-26 is counter 2, decoded by the decoder at output 37, only corresponds to

40 to the number of one switching element of block 4. In block 4 there is a group of switching ones. elements, when pressed, the generator 8 of a single pulse at the output 46 with interruption

45 produces impulses. The numbers of these switching elements correspond to those codes of counter 2, which are decrypted by decoder 13 at output 36. When a signal appears on

50 in the output 36 of the decoder 13, the element 6 prohibits the passage of signals from the output 42 of the unit 4 through the element 5 for a time that is sufficient to set the generator of the 8-only 5 pulses to the initial state. Element 6 works only if there is a signal at the output of 30 counter 2 The decoder and multiplexer can be built on KP2 chips

3 13 series 564 with bidirectional outputs. The register bit 9 is equal to 8. Triggers 10 and 11 are of the type R-S-flip-flops, the S-inputs of which are assembled according to the scheme I.

Thus, the invention provides additional information entry modes.
