Description

The invention relates to automation

and computing and maybe

used in professional selection

operators of various control systems.

The purpose of the invention is the expansion of the didactic capabilities of the simulator due to the processing of stored and stored information after playback by subsequent identification of the introduced errors.

The drawing shows a structural diagram of the simulator.

The device contains a generator unit 1, a unit 2 for presenting educational information, a unit for setting standards (the number of stimuli), a block 4 for entering errors, a block 5 for specifying time (exposure), a block 6 for control, a block 7 for registering and a console 8 for the operator.

Unit 1 contains a generator of 9 single pulses and a generator of 10 clock pulses.

Block 2 includes a shaper 1 1 random sequence of codes, the element And 12, the adder 13 modulo two, the ring shift register 14 and the element And 15.

Unit 3 contains a counter 16 pulses, multi-position switch 17 and the inverter 18.

Block 4 contains one-shot 19 and 20 and ring shift registers 21.

The exposure unit 5 includes standby multivibrators 22 and 23 (the pulse duration at the output of the second multivibrator is two times less than the first), the OR element 24, the key 25 and the power source 26.

Block 6 contains a ring shift register 27, element 28, delay element 29, counter 30 (correctly indicated errors) and indicator 31 (“Enter the error”).

Block 7 includes elements AND 32, a multi-input element OR 33, a counter 34 of correct answers, a multi-position switch 35, an element OR 36, a counter 37 of answers and an indicator 38 "End".

The remote control 8 contains buttons for the location of stimuli, indicators 40 and buttons 41 for the digital series.

The simulator works as follows.

After turning on the power, press the "Set to" 0 "button in block 1 (not shown), starting this generator 9, the output of which goes to the inputs, register 14, GB counter and registers 21, as well as to the inputs 34 and 37 ( not shown), setting them to their original (zero) state. In the register 27 enter the "unit". The switches 17 and 35 are set to the position corresponding to the number of stimuli presented to the student. Then, using the “Record” button (not shown), the generator 10 is connected to the clock inputs of the driver 11 and through element 15, to which the unit potential from the output of the inverter 18 is applied, to another input of the register 14. The driver pulses 11

through the element 12 and the adder 13 are received simultaneously to the input of the register 14, filling it randomly, and to the input of the counter 16, which counts the number of received units. As soon as their number reaches the value set by switch 17, a signal is received from its output to the input of inverter 18, which removes a single potential from the inputs of elements 12 and 15, turns off the driver 11 from the information input of register 14 and stops supplying clock pulses. The unit potentials recorded in register 14 are fed from its outputs to the inputs of one-shot 19, the pulses from the outputs of which, arriving at the corresponding inputs of registers 21, record “one” to the discharge to which the output of the corresponding one-shot 19 or 20 is connected.

When ready, the student presses the “Exposure” button of unit 1 (not shown), and the signal from the output of the generator 9, arriving at the input of the multivibrator 22, produces a single pulse, the duration of which is equal to the exposure time set in advance. The impulse from the output of the multivibrator 22, acting through the element 24 on the control input of the key 25, provides the ignition voltage from the output of the source 26 to all the inputs of the indicators 40. In this case, only those indicators and numbers on them that receive the control signals from the registers 21 are displayed.

The subject visually captures both the numbers and the placement of the indicators on which these numbers are highlighted. Then he reproduces the stored information by pressing the button 39 of the flashing indicator and the button 41 of the digital series corresponding to the flashing digit on the indicator 40.

When the button 39 is pressed, the outputs of the corresponding register 21 are switched from the indicator 40 to the elements 32 of the block 7. If a stimulus is displayed in this indicator 40, then the input potential of one of the elements 32 enters. When the student correctly reproduces this stimulus using the button 41 from the generator 9, the unit is recorded through the corresponding element 32 and element 33 in the counter 34.

If the stimulus or indicator on which the stimulus flashes is incorrectly indicated, then two units do not go to one of the elements 32 at the same time, and the counter 34 does not count. In this case, after playing all the stored information, the indicator 31 does not turn on, and the student must repeat the cycle from the beginning.

If the learner reproduced correctly

all information then after playback

item 28.

Simultaneously, the pulse from the output of the generator 9 through the button 41 and the element 36 enters the counter 37, fixing the answer, passes through the element 28 to the input (shift) of the register 27 and moves the “one” to the next digit. A single potential from the output of the register 27 is fed to the input of the one-vibrator 20 of one of the nodes, and the pulse from its output moves the unit in the register 21, i.e., introduces an error.

From the output of element 28, the impulse also arrives at element 29, highlights the “Indicate the error” indicator 31, and sets the counter 30 to the initial state. After a delay time of 1-2 s, the pulse from the output of the element 29 turns off the indicator 31 and enters the input of the multivibrator 23, which produces a single pulse. This pulse provides a flashing of the indicators 40 and the numbers on them. The student visually looks for, and then fixes the indicator in which he detected the error and the numerical value of the error.

If the trainee correctly reproduces the error, the latter is recorded at 20

30. The pulse from the output of element 28 simultaneously enters the input of register 27 and moves the “unit” to the next digit, thereby ensuring the introduction of a new error, as it changes the state of one of the registers 21.

If the student incorrectly reproduces the error, the cycle repeats from the beginning.

The use of the invention in devices for training memory expands didactic capabilities by processing information stored and stored after reproduction (locations of incentives and their digital values) by subsequently presenting the learner against the background of correctly stored information of a randomly entered error and identifying its location and digital value. The definition of the accidentally introduced error and its location on the information board allows the training conditions of operators to be closer to the real ones. This leads to an improvement in the quality of service for operator control systems by increasing the correcting ability of the human-machine system.
