The invention relates to automation equipment and can be used to control the actual level of training of operators of keyboard (telegraph) apparatuses in the learning process.

The aim of the invention is to expand the didactic capabilities of the device by ensuring the operator's conditions on the simulator are adequate to real conditions, under which it is possible to correct the errors noticed by the student according to the established rules and not to take them into account when assessing the actual level of training of the learner.

After each error made by the operator, the further transmitted symbols are analyzed. If, after the error, there is a sequence of characters (F, W), this means that the trainee himself measured his error and began to correct it. In this case, after transferring the characters of the interrupt combination (F F Space) in the proposed device, further control of the accuracy of information transfer is maintained from the first character of the last correctly transmitted word. The cell selection of the on-line memory device, in which the code combination of the character to be transferred to the student is stored, is performed using a reversible counter.

is set to the state that determines the address of the code combination of the first character of the last correctly transmitted word, and therefore further control of the accuracy of character transmission begins with this character, the total number of errors made by the operator is recorded by another reversible counter. However, errors observed by students after they have been corrected according to established rules are immediately subtracted from the total number of errors recorded by this counter.

Block 2 is designed to store code combinations of characters of the text of the task, switch 3 to set the address in block 2 when writing or reading information, AND 4 is for

selection of a SPACE character code combination (in the MTC-2 code, the SPACE character combination is 00100) separating one word from another in the text of the task.

The device also contains a task indication unit 5 for displaying on the display a symbol of the text of the task to be before the student, a comparison unit 6, an address counter 7, a switch 8, an AND 9 element, a space counter 10, for generating the installation signal when the control unit receives two pulses from the output of the AND 4 element at its counting input, the operator response input block 11 is used to transfer the characters of the task text to the students. Block 11 is a keyboard sensor and provides the formation of a binary code of a character and a synchronization pulse during transmission using the keyboard text of the task.

the countdown inputs of counters 12 and 13, and two inputs, one of which is connected to the output of the generator 15, and the other to the output of the element OR 21.

Block 20 is designed to visually monitor the total number of errors made by the operator, the OR 21 element is used to generate a fictitious error signal recorded by the counter 13. The OR 21 element has inputs connected to the outputs of the counter 13, and an output connected to the selection enable input of the block 18 and the input element and 19,

A single vibrator 22 is designed to form a single rectangular pulse at the falling edge of the return signal generated by block 18,

Elements 23 and 24 are designed to separate the code combinations of the G and SPACE symbols, respectively (in the MTK-2 code, the code combinations of these symbols are as follows: G 01111, SPACE 00100) from the stream of combinations received from the information outputs of block 11,

Elements 25 and 27 are intended to form the reset pulses of the initial state of block 18 when the correct combination of symbols is transmitted by the trainer to a fault.

Elements 26 and 28 are intended to form counting pulses for the distributor 30 when transmitting to the learner symbols of a reboot. Pulses through the AND 33 to the counting input of the distributor 30 only if there is a signal of the presence of a fictitious error coming from the output of the OR element 21 to the input of the AND 33 element.

The device works as follows

The signal coming from the output of the shaper 16, all blocks of the device are set to their original state -

set to state O, at the outputs of the distributor 30, the signal of the logical unit is set to the first output. The zero state of the counter 13 causes the absence of a signal of the presence of a fictitious error at the output of the element OR 21, and the absence of a return signal at the output of the block 18

ensures that the generator 15 is off and the counter 10 is set to the zero state. In addition, the Reset pulse arriving at the input of the imager 1 ensures that it starts and rewrites the code combinations of the characters of the text of the task to be transferred to the students from the imager 1 in block 2. In this case, the switch 8 should be in the Record position. A sheet with the text of the task, the code combinations of the characters of which are recorded in block 2, is issued to the student before starting work. The transfer of this text is accomplished by the learner pressing the corresponding keys of block 11. The transfer of each character of the text is accompanied by a comparison using block 6 of the code combinations received from block 11 with the code combinations of the characters of the task recorded in block 2.

After transferring the next character of the text of the task, the code combination of the next character is set at the information outputs of block 2. Block 2 is controlled by counter 7. Each pulse generated at the synchronization output of block 11 through the primary element OR 14 to the input of counter 7 provides an increase by one state unit, which determines the address of the character pattern of the task text. If the student makes no mistakes, then the remaining units of the device are not involved in the work. After the execution of the task, the counter 12 in this case remains in the zero state.

When dealing with errors, there are two possible actions for the student. In the first variant, the student himself notices the mistakes made by him, corrects them according to the established rules, and continues to send texts further. In this case, the error signal generated by block 6 is recorded by the counters 12 and 13. The combination symbols transmitted after the error signal are recorded by the allocation circuit of the combination of block 18. Because of the inconsistency of the symbols of the combination of symbols transmitted by the block and the symbols of the text of the task 2 at the output of the mismatch of block 6, pulses are formed, which are also detected by counters 12 and 13, If

then from the number recorded by counter 12, subtract the number recorded by counter 13, then the counter

12 is set to the state in which it remains until the moment the student has committed an error. Thus, the error corrected according to the established rules is not counted to the student. The transition to the transfer of the last correctly transmitted word during error correction is accomplished by decreasing the state of the counter 7.

In the second case, the student transmits the text without noticing the error made by him. In this case, as in the first case, the error signal is recorded by the counters 12 and 13. However, after the transfer to the student, the words in which he

o made a mistake, the counter 13 by the pulse formed at the output of the element And 9 (with the correct transmission of the SPACE character following the word in which the student committed an error),

5 is set to the zero state, and the counter 12 retains its state. Thus, in the counter 12, all the uncorrected errors by the learner remain fixed.

Consider the work in the first case. The error signal generated at the output of the block 6 mismatches is fed to the direct counting inputs of counters 12 / and 13. The presence of at least one dummy error recorded by the counter 13 ensures that a fictitious error is generated at the output of the OR element 21. the input of the resolution of block 18 and the arrival of the 18 characters of the combination of 18 symbols on the information inputs of the same block cause a return signal to form at its output. This signal permits the formation of pulses at the generator output of 15 rectangular pulses, does not permit the formation of a counter reset pulse at the output of the And 9 element.

13 and allows the counting of SPACE characters in the counter 10.

From the output of the generator 15, the pulses passing through the element I 19, opened by a signal of the presence of a fixed error, arrive at the counting inputs of counters 12 and 13. The states of both counters are reduced until the counter 13 is set to zero and the output of the element OR 21 action signal presence

bogus error is terminated. Thus, the counter 12 remains in the state in which it was before the trainee made the last error.

The return to the beginning of the last correctly transmitted word is accomplished by decreasing the state of counter 7 with the help of rectangular impulses generated by the generator 15 and arriving at the countdown counter 7 input. In this case, the information outputs of block 2 are sequentially formed previously transferred to the trainee. A sign of the beginning of the last correctly transmitted word is the receipt from these outputs of block 2 of two code combinations of the SPACE character, which are detected by the element AND 4. When the AND 4 element arrives at the counting input of the counter 10, two pulses are output at the output of the last initial unit 18 to its initial state. After that, the signal at the output of the unit is terminated. Thus, the state of the counter 7 returns to the cell of the block 2, in which the code combination of the SPACE character before the last correctly transmitted word is recorded. The transition to the first character of the last correctly transmitted word occurs via a pulse coming from the output of the single-vibrator 22 through the OR element 14 to the input of the counter 7. The one-timer 22 is triggered on the falling edge of the return signal generated by the block 18.

In the second case, when the trainee does not notice the error and continues to transmit the text further, all errors are recorded in the counter 12-. A sign that the trainee did not notice his mistake is that the trainee passed on the text of the task of the SPACE character There is a mistake in the whale.

The error signal generated at the output of mismatches of block 6, as in the first case, is recorded in counters 12 and 13. However, the reset pulse generated by element 9, when transmitting the SPACE character, sets counter 13 to the zero state. In this case, the device blocks are reset, and

the error made by the student remains recorded in the counter 12.

The use of the proposed device for training operators of keyboard apparatus is advantageously different from other known training devices, since the provision of real working conditions for operators increases the efficiency of their professional training. Experience training keyboard operators showed that 70% of errors the student can notice and correct them according to established rules.
