Description

The invention relates to automation and can be used for the professional selection and training of the memory of operators of various control systems.

The aim of the invention is to expand the didactic capabilities of the device.

FIG. 1 shows a block diagram of the device; in fig. 2 - functional device diagram.

The device for training the trainee's memory contains a block 1 of generators, a block 2 for presenting educational information, a block 3 setting standards, a console A of the learner, a block 5 of analysis. responses, control block 6, registration block .7.

Generator block 1 includes a generator of 8 random numbers and a generator of 9 clock pulses.

Unit 2 of the presentation of educational information contains registers 10 and 11, | Decoder 12 and indicator 13.

The standard setting unit 3 contains parity devices 14 and 15, a comparison device 16, a comparator 17, element 2ILI 18, element 19 2I.

The student's console A includes a Seri switch, consisting of two buttons 20 and 21, switches 22 Blanking and 23 Result.

Block 5 analysis of the answers contains an inverter 2A, elements 2I 25-28.

The control unit 6 has a register 29, a D-trigger 30, a Schmitt trigger 31, elements 2ILI 32 and 33, elements 2I 34 and 35.

Block 7 of registration contains counters 36-39, decoders 40-43, indicators 44-47.

The device works as follows.

Turn on the power. Generators of 8 random numbers and 9 clock pulses of block 1 of generators are started.

Pressing the button 20 (Seri 1 high potential arrives at the first input of the register 29 and the second input of element 2ILI 32, and at the output of element 2IPI 32 there appears a high potential that enters the inputs of the installation in O of binary decimal counters 36 -39 block 7 and the input of the installation in the On trigger 31 block 6.

Accordingly, the counters 36-39 of block 7 are zeroed, and a low potential is established at the output of the trigger 31.

which enters the inputs G of the decoding of the decoders 40-43, turns off the indicators 45-47.

In addition, the pulse from the output of element 2ILI 32 is fed to the input C of the register 29, while the rising edge of the pulse (when the button 20 is released) at the output of the register 29 sets a high potential, which through element 2ILI 33 enters the second input of element 2I 34 and thereby allowing the passage of clock pulses from the output of the generator 9 of block 1 through element 2I 34 to the input C of the register 10.

On the falling edge of each clock pulse, an eight-bit binary-decimal code of a random number from the output of the generator 8 is recorded in register 10. In this case, the previous contents of register 10 (if the stimulus presentation cycle is not the first) are written to register 11.

At the same time, the contents of register 10 are fed to the information input of the decoder 12. A clock pulse arriving at the recording input of trigger 30 causes a high potential at its output (since a high potential is constantly applied to the information input of the trigger 30), which is fed to the input of the decoder 12, allowing the passage of a fourteen-bit code to the input of the indicator 13. Thus, on the indicator 13, a stimulus in the form of a two-digit decimal number presented to the subject is displayed. In addition, the clock pulses from the output generator 9 of block 1, entering the input of record 36 of block 7, through the decoder 40 fix the number of stimuli presented to the operator on the indicator 44 of block 7.

After the first two clock pulses arrive at the recording entries of registers 10 and 11, the eight-digit codes of the first and second stimuli arrive from their outputs to the parity check devices 14 and 15, respectively, and to the corresponding inputs of the comparison device 16. For the first mode (Seri 1), when the operator does not perform parity analysis of the stimuli presented, it does not affect the result of the comparison. This is achieved by the fact that at the second input of element 2ILI 18 from the first output of register 29

served high noreHunaj; Consequently, regardless of the result of the parity check, i.e. regardless of the signal at the output of the comparator 17, which enters the first input of element 2IL or 18, at the output of element 2IL or 18 there will be a high potential.

Therefore, for the first operation mode of the device (Series 1), eight-bit stimulus codes of the comparison device 16 are used. In this case, if the stimulus code entering the input of the comparison device 16 is larger in magnitude of the stimulus code entering the input, a high potential appears at the output of the matching device 16. Conversely, if less, then the potential of the comparison device 16 will be low.

Thus, if the second stimulus is greater than the first, there will be a high potential at both inputs of element 2I 19, and hence at the output of element 2I 19, from where it goes to the first inputs of elements 2I 28 and 26 and to the input of inverter 24.

After presenting the first two stimuli to the operator, he compares their numerical values. If the second stimulus is greater than the first, then the operator must redeem the second stimulus by pressing the Cancel button 22. In this case, the high is fed to the input of the set to zero of the trigger 30, as well as to the second input of the element 2I 35. At the code of the element 2I 35, a quench pulse is produced, which goes to the second inputs of the elements 2I 28 and 27. the input element 2 and 27 - zero potential, coming from the output of the inverter 2A.

Thus, at the output of element 2 and 28, a high potential appears at the counting input C of the counter 37 of the block 7, which fixes the correct decision of the operator.

If the operator errs, he pressed the Blanking button 22 under the condition, then at the output of element 27 there appears a unit potential arriving at the output of counter 39, which records the number of incorrect decisions of the operator.

After the end of the first part of the experiment, the operator presses the button 23

go A high potential arrives at the setup input to register zero 7.9, discontinuing the stimuli on the indicator 13 of block 2. and on the single input of trigger 31 of block 6. At the output of trigger 31 there is a high potential that goes to the inputs Quenching depressors 41 -43 block 7, highlighting on the indicators 45-47 block 7 information recorded by the counters 36-39 block 7.

Next, the second part of the ex periment begins. Now the operator should

make a comparison of the value for even and odd numbers separately. If the subsequent stimulus presented will be greater in magnitude than

0 the previous stimulus, and the same parity with it, the operator must extinguish it by pressing the button on the remote 3.

To start the second part of the experiment, the operator presses the button 21

5 switch seri. A single pulse arrives at the second input of the register 29 and through element 2ILI 32 at the input from the record of the register 29, causing the appearance at its second output

Q high potential, which through the element 2ILI 33 permits the passage of pulses from the generator 9 to the recording inputs C register-in 10 and 11 of block 2 and the counter 36 of block 7.

The operator is given random

 two-digit decimal numbers from generator 8 of block 1.

The eight-digit code of the first number enters from the output of the register 11 to the input of the comparison device 16 and to the input of the device 15 parity, and the eight-digit code of the second number comes from the output of the register 10 to another input of the comparison device 16 and to the input of the device 14 cont5 1

roll parity. If both numbers are even

at the outputs of devices 14 and 15 will be 1, arriving at the inputs of the comparator 17. At the output of the comparator 17 the same potential appears. If both numbers are odd, the outputs of devices 14 and 15 will be O, which, entering the inputs of the comparator 17. also cause the appearance of 1 at its output. The unit potential through element 2ILI 18 is fed to the second input of element 2I19, the first input of which receives a signal from the output of the comparison device 16. If a

the second number is greater than the first, the output of the device 16 is 1. Therefore, a high potential appears at the output of element 2 and 19. If the operator has made the right decision and when a second stimulus appears on the indicator 13, he pressed the button 22, then the counter 37 will record the correct answer through element 2И 28.

If the operator did not press button 22, i.e. For some reason, I did not make the right decision, there will be unit potentials on both inputs of element 2 and 37 and, accordingly, it will also have 1 output. This leads to appearance 1 at the output of output 26 and 26 and the counter 38 will record the passage of the correct solution.

In the event that one of the numbers given to the operator is even and the other is odd, the parity of the parity check device 15 will be 0. Therefore, the output of the comparator 16 will be O, which leads to the appearance of O at the output of the element 2И 19.

If the second stimulus is equal to or less than the first one, then the output of the device .16 is a comparison and the output of element 2I19 will also be O.

If the operator did not notice at least one of the conditions for the correct solution (of the same parity, y, x) and pressed the Cancel button 22, then the output of element 2 and 27 is high and the counter 39 of block 7 will record the wrong decision of the operator.

To complete the second part of the experiment, the operator must press the button 23 Result. According to the results of the experiment, read from the indicators 44-47, such important characteristics of the RAM as memory storage, storage time and accuracy of the reproduction of the material are judged.
