ABOUT

The invention relates to automation and computer technology, in particular to simulators, can be used in psychophysiological studies and is an improvement of the known device according to the author. ev, Ms 1679522.

In the main invention, a device for evaluating and training reactions is described, comprising sequentially included an operator response input unit, a pseudo-random sequence generator (PSP), a key, a demultiplexer, a signal generation unit, the group outputs of which are connected to the corresponding inputs of the display unit, an And block of information the input of which is connected to the output of the timestamp generator, and a recording unit, a controlled switch, a switch, an end-stage signaling unit, and a control unit the first and second outputs and the first input of which are connected to the corresponding inputs and output of the signal conditioning unit, respectively, the third and fourth outputs - with the first and second inputs of the controlled switch, respectively, and the fifth output - with the input of the operator response input unit, the second output of which is connected to the third inputs of the signal conditioning unit and the control unit, and the third output - with the second input of the control unit and with the fourth input of the signaling unit at the end of the stage, the first and second inputs of which are connected ln the corresponding output of the switch, the third input is connected to the input of the switch and connected to the second output of the controlled switch, and the output is connected to the fourth input of the control unit, the fifth input of which is connected to the second input of the key and connected to the first output of the controlled a switch, the third input of which is connected to the second output of the PSP driver.

However, this device does not allow detecting delayed responses (they are not fixed), which makes it impossible to assess the functional state of the operator, reduces the objectivity of the assessment, narrowing the functionality of the device.

 The aim of the invention is to expand the didactic capabilities and increase the accuracy of the device by determining the functional state of the operator by identifying and fixing delayed responses.

This is achieved by introducing into the device for evaluating and training reactions

an audio signaling device and a delayed response recording unit, the group inputs of which are connected to the corresponding outputs of the group of the signal generating unit,

the output is with the input of a sound signaling device, and the group outputs are with the corresponding inputs of the second group of the registration unit, as well as the fact that the unit for recording delayed responses contains a group of AND elements,

the outputs of which are the output of the block group and are connected to the inputs of the first OR element, the output of which is the output of the block, and the second OR element connected in series, the inputs of which are connected

They are with the first inputs of the elements of the And group and are the input of the group of the block, the one-shot and delay element, the output of which is connected to the second inputs of the elements of the And group.

These new features make it possible to identify

and warn the operator (manager) of delayed reactions, i.e. responses whose reaction time exceeds 0.8 s.

In FIG. 1 shows a block diagram of a device; in FIG. 2 is a functional block diagram of the registration of delayed responses; in FIG. 3 is a diagram of a registration unit; in FIG. 4 are timing diagrams explaining the operation of the device when highlighting delayed responses.

A device for evaluating and training reactions includes a driver 1 of the PSP, a key 2, a controlled switch 3, a control unit 4, a switch 5, a demultiplexer 6, an operator response input unit 7, a signal generating unit 8, an indication unit 9, an element block 10, and a time stamp generator 11, a recording unit 12, an otap end signaling unit 13, a delayed response recording unit 14, and an audio signaling device 15.

Block 14 contains a group of elements And 16i-164, the first and second elements OR 17 and 18, a single vibrator 19 (short-pulse shaper) and a delay element 20.

Block 12 contains a group of counters 21 g 21 / fixing the reaction time by color and a group of counters 22i-22 / i fixing the number of delayed responses (reaction time is longer

0.8 s) by color.

The device operates as follows.

Turn on the power. Block triggers 3, 4, 7, and 13, block 5 register, and block counters

4, 8 and 12 are initialized. From the first output of block 7, a zero potential is applied to the control input of the driver 1. At the second output of the driver 1, an SRP pulse appears

that come through (pseudo-random

a controlled input of key 2, to the information input of which clock pulses are supplied from the first output of the SRP driver 1. Clock pulses from the output of key 2 are fed to the information input of the demultiplexer 6, providing a pulse at its output. When five clock pulses appear at one of the outputs of the demultiplexer (a single SRP pulse from the output of shaper 1 consists of five units), a pulse appears at the output of signal generating unit 8, which arrives at the first input of control unit 4, causing at its fifth output of a single pulse. This pulse, applied to the input of the operator response input block 7, provides a unit potential at its first output, which, upon entering the former 1, stops the extension of pulses and SRP by blocking its first and second outputs and notifies the operator that the device is ready for the presentation of colored light signals (irritants). The operator (trained) by pressing the key-button in block 7 releases the blocking from the first and second outputs of the driver 1, applying zero potential to its input from the first output of the block 7, and provides the supply of clock pulses and SRP to the information and control inputs of the key 2, respectively.

When, at the first output of the group of the demultiplexer 6, for example, three clock pulses appear, the latter arrive at the first input of the group of unit 8, providing the appearance of the unit potential group at its third output (Fig. 4a). which is applied to the corresponding input of block 9. by highlighting the indicator of mountains of a certain color, to the corresponding input of the group of block 10, ensuring the passage of time stamps from the output of the generator 11 to the counting input of the corresponding counter 21 of the recording block 12, and to the corresponding input of the group of block 14, to the first input the corresponding AND element 16 and the input of the OR element 18.

The operator, seeing the glow of the indicator on block 9, releases, and then presses the key-button of block 7. When releasing the key-button, a single pulse from the second output of block 7 goes to the third input of block 8, stopping the supply of a single potential from its output (Fig. 4h) . The receipt of time stamps in the counter 21 of block 12 is stopped. The indicator on block 9 goes off. Subsequent key-button presses returns block 7 to its initial state. The pulse applied to the input of the OR element 18 of block 14, comes from the output of the last

to the input of the one-shot 19, causing a short pulse to appear at its output (Fig. 46), which is fed to the input of the delay element 20), If the response time

less than 0.8 s (Fig. 4a - the first pulse), then the delayed pulse from the output of the element 20 (Fig. 4 c) does not pass through the And 16 element, since there is no unit potential at its first input - it is cleared by releasing the key of the button of block 7 If the response time is more than 0.8 s (Fig. 4a is the second pulse), then the delayed pulse from the output of element 20 is fed to the second input of I / I element 1 b, causing a phenomenon at its output

the pulse that passes to the counting input of the counter 22 of block 12, fixing the delayed response (according to the color provided) and through the OR element 17 enters the input of the signaling device 15, warning the operator with an audible signal about a delayed response to the corresponding color.

The next presentation of the color signal is carried out at the next supply of a single potential (impulse) of the SRP,

while the operation of the blocks is similar to that described above.

The repeated occurrence of sound signals warns the manager about unsatisfactory functional

the state of the learner.

The use of the invention in psychophysiological studies and training of operators, in comparison with the prototype, allows to determine the functional state of the learner in a timely manner, to prevent a decrease in the accuracy and objectivity of evaluating the result of reactions when responding to color signals, reduces training time by eliminating ineffective training, and to reveal color signals not distinguishable by the operator, as they are recorded as delayed responses.
