Description

The invention relates to automation and computing and can be used in the professional selection of operators of various control systems.

The aim of the invention is to improve the accuracy of the device.

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

The device for estimating the speed of the operator’s response contains an operator response input unit 1, a control unit 2, a multiplexer unit 3, a random number generator 4, a memory unit 5, counters 6 symbols and time 7, a display unit 8. The operator response input unit 1 contains (FIG. 2) switching elements 9-12.

The control unit 2 includes switching elements 13 and 14, a switch 15 (device operation mode).

trigger 16, the element OR i7 and the elements AND 18 and 19.

Unit 3 multiplexers consists of multiplexers 20-24.

The random number generator 4 includes a generator of 25 high frequency pulses, elements 2 and 26 and 27, as well as counters 28 and 29 pulses.

Block 2 also contains a generator 30 pulses and the element is NOT 31,

The display unit 5 contains decoders 32-35, indicators of the number of symbols 36, symbols presented (presentations of the figure) 37, assignment of one variant 38 and time 39.

The device works as follows.

The operator presses element 13 (the Start button), while the high potential (1) is fed to the input of the element OR 17 of block 2, the single input of the trigger 16, the outputs of zeroing the counters of symbols 6 and the time 7. Following (

Outside this, the trigger 16 goes into one state, the counters 6 and 7 are zeroed, and at the output of the element OR 17 but there is a high potential that goes to the second inputs of the elements 2I 26 and AND 19, thereby permitting the passage through the first input of the element 2and 26 high-frequency clock pulses (6-10 MHz) from the output 10 of the generator 25 to the counting input of the counter 28,

If switch 15 (Mode i - Mode 2 operation mode) of the device is in position Mode 15

. (Fig. 2), at the first input of the element And 19 and, accordingly, the output will be a high potential, which, entering the second input of the element 2 and 27, will ensure the passage of pulses with 0

the output of the generator 25 through the first INPUT element 2 and 27 on the counting input of the counter 29.

Thus, while element 13 is pressed, the counters 28 and 29 of the pulses consider the pulses coming from the generator 25, and since the frequency of the pulses is large and the holding time of button 13 the start-up is unstable (varies from experiment to experiment), then at the moment the button 13 is released counters 28 and 29 generate random numbers. One of the numbers in a two-bit bottom binary code will come from the outputs of counter 28 to the inputs of the decoder 33, which, in turn, will highlight the symbol on indicator 37 corresponding to the output code.

Because. until elements 9-12 of block 1 are pressed, the inverse of the output of multiplexer 24 is high potential, which is fed to the first input

element 18, at the second input of which there is already a high potential coming from the output of the trigger 16, therefore, from this moment the counter, 7 starts counting the pulses from the generator output 30 seconds pulses through the elements 18. The counter 7 shows in a two-digit binary The code comes from the output of counter 7 to the input of the decoder 35, where they are converted into a decimal code and then displayed on the time display 39. The random number, formed in the counter 29, arrives at the address input of block 5 (ROM), in which the information is pre-recorded in

according to the table, which contains the contents of the ROM cells.

The code from the output of block 5 is fed to the addressNEC inputs of multiplexers 20-23, which in accordance with the table will switch the outputs of block 1,

If, for example, in block 5, cell 1 is selected, the signal from element 9 1 passes to the input of multiplexer 20 from element 10 2 to input of multiplexer 21, from element II 3 to input of multiplexer 22 and from element 12 4 to input of multiplexer 23 .

At the same time, the signal from the output of block 5 through the decoder 34 enters the input of the indicator 38, on which the option of matching the elements 9 1, 10 2, 11 3, 12 4 to the displayed symbols, which are turned off by the corresponding element of block 1, is highlighted.

The binary code of the symbol from the output of the counter 28 goes to the address inputs of the multiplexer 24, thereby connecting one of the multiplexers 20-23 corresponding to the given symbol ..

After some time, which

is determined by the reaction rate of one

Ratio, he presses one of the elements 9-12, corresponding to the highlighted option. If the element is pressed correctly, the high potential will pass through ONE of the multiplexers 20-23 and through the corresponding input of the multiplexer 24 will go to its direct output and then to the counting input of counter 6, while its content will increase by one.

Thus, the contents of the counter 6 will correspond to the number of presented (correctly guessed) characters and with the help of the decoder 32 will be displayed on the indicator 36.

At the same time, the low potential from the inverse output of multiplexer 24 will go through the element NOT 31 to the input of the element OR 17, thus including random number generators, to the first input of the element And 18, thereby prohibiting the counting of time.

If switch 15 (Mode 1 - Mode 2) is in the lower position (according to the scheme), i.e. the device operates in mode 2, then when you press the elements 9-12, the pulses to the input of the counter 29 will not pass, as the low potential from the switch 15

through the element And 19 comes to the second input of the element 2I 27. In this case, the option is set when pressing the element 13 (Start), the high potential from the output of which through the switch 15 comes from the generator 25 to the counter 29,

After the device has finished working, the operator presses element 14 (Stop), while the high potential arrives at the zero input of the trigger 1 6 and sets it to the zero state, and the low potential from its output is shown through the counter 7.

I

The rate of the selection reaction is estimated by the magnitude of the quotient based on dividing the total task execution time by the number of pieces worked.
