The invention relates to computing and automation and can be used to control processes through a computer. A device is known that contains two registers, two descriptors, an encoder, two blocks of elements, a switching block, an input and output block, a switch, reset, enable and register elements. The drawback of the device is that the structure of the device is not adapted to output potential signals. build device modifications. The closest to the proposed invention is an information input device 12} comprising a keyboard, an encoder, a memory unit, first and second pulse distributors, a switch, an OR element, a pulse generator, a single vibrator indication unit, an inverter. The drawback of the device is its limited speed, since it does not provide potential signals and the indication of signals from an external device that makes it difficult and slows down the work of the operator. The purpose of the invention is to increase the speed of the device by ensuring the issuance of potential signals of multiple repetition of operations, automatic monitoring of the device's performance, indication of information of the external device. The goal is achieved by the fact that the device containing the first keyboard, the output of which is connected to the first input of the encoder, the first output of which is connected to the first input of the AND element, the output of which is connected to the input of the one-vibrator, the second output of the encoder multiplexer, the second input of which is connected to the output of the first pulse distributor, the first output of the second pulse distributor is connected to the first input of the first register, the output of which is connected to the first input of the display element block, the second input is connected to the third input of the multiplexer selector, a second keyboard, a trigger block, an amplifier block, a second register, and an IS-NOT element are entered, the first input of which is the first input of the device, the first, second and third outputs of the second keyboard are connected to the fourth selector input -multiplexer with the first input of the block of triggers and with the second input of the NAND element, the output of which is connected to the second input of the AND element, the second output of the second pulse distributor is connected to the first input of the second register, built-in The first and second outputs of the second register are connected to the second output of the first register and to the first output of the amplifier unit, the second and third outputs of which are connected to the second input of the encoder and the second input of the trigger unit. connected to the second input of the display element unit, the first and second inputs of the amplifier unit are connected to the outputs of the one-shot and selector-multiplexer, the fourth output and the third input of the amplifier unit are output and volts eye input device. The drawing shows a functional diagram of the device. The device contains the first and second keyboards 1 and 2, the encoder 3, the selector-multiplexer 4, block 5 of the trigger, block b of amplifiers, the first and second pulse distributors 7 and the first register 9, the second register 10, block 11 of the display elements, the clock signal 12 , element AND-HE 13, element AND 14, one-shot 15, the first and second communication buses 16 and 17. The device operates as follows. When typing text or other data for a computer, the operator on the first keyboard 1 presses the corresponding keys, the signal from the fiHX is encoded by the coder 3. The code from the coder 3 is fed to the input of the selector-multiplexer 4, where it is stored for the time the keys are pressed. When pressing any of the keys of the first keyboard 1 to the encoder 3, a signal is additionally generated, which, through element 14, goes to the one-shot 15, the one-shot 15 selects the leading edge of the signal and gives a pulse to the block S of amplifiers which is connected to the computer in a accepted discipline exchange, then produces a series of signals to the first distributor 7 pulses. The latter allows the signal to pass through the selector-multiplexer 4 to the amplifier block b from the encoder 3 first spruce, and then transmits information from the block 5 trigger and the second keyboard 2 (second spruce. The amplifier block 6 issues these words to the computer. When you press the next key of the first Keyboard 1 transfer cycle is repeated. Thus, all text is typed (data ;. In the device for transmitting potential signals, an additional word is allocated, which is fed to block b of amplifiers through selector multiplexer 4 from block 5 of flip-flops and the second keyboard 2. In this case, the transfer of potential signals is provided without increasing the number of connections to the external device. The triggers of block 5 are switched to the opposite state. By means of the second keyboard 2, when the corresponding keys are pressed. The trigger status of block 5 is indicated by a block of elements. indication that allows the operator to set the desired state.

In order to receive and signal the signals from the computer, the amplifier block b receives 17 bytes of the computer via a bus 17 and sends them to the second register 10 and the first register 9. The second pulse distributor 8 signals the recording resolution from the amplifier block b information in one of the registers 9 or 10. Signals from the second register 10 arrive at the block 11 of the display elements — and are visually accessible to the operator.

The bits of the first register 9 are used as separate packs of cx signals and, in particular, for switching the triggers of block 5 as a command, which is similar to a command from keyboard 1 through encoder 3, selector-multiplexer 4 and block b of amplifiers are transmitted to computer and etc.

The generation of a command from a signal from the first register 9 allows the organization to automatically control the device. So, after receiving the control message containing for the first register 9 bit-command, a two-word (control command and state of the trigger block 5) message will be generated and issued. The receipt of the correct message by the external device indicates the health of the device, since all the main units of the device are involved in receiving the control and issuing response messages.

To reduce the number of keystrokes of the first keyboard 1 when the command is executed several times and to increase the speed of entering information on the second keyboard 2, the Repet key is entered. To repeat the command several times, the operator simultaneously presses the key of this command on the first keyboard 1 and the Repeat key on the second keyboard 2. Oj Repeat keys set a single level from the second keyboard 2 to the input of the AND-NOT element 13, which causes the signal to be interrupted by the AND 14 element with the frequency of the clock signal 12. This results in issuing to the device bus 17 a pressed command with the frequency of the clock signal. -

Switching triggers block 5 is equivalent to pressing a key of the second keyboard 2, i.e. access to the keyboard is provided to both the operator and the external device (computer), which increases the efficiency of human interaction with the machine.

The proposed device provides the following additional functions, i.e. issuing potential signoshes without increasing the number of external communications by allocating an additional word; repeating operations multiple times due to the introduction of the Repeat key; automatically monitoring the device performance by issuing a two-word message by the device in response to the control message received at the device input and contained in the control register signals of the remote d-command, indication of information of the second device using the display register and the block of display elements.
