The nodes 1-4 and 21 and the register .4 7 are the evaluation task setting block 54, the blocks 5, 6, 22, 23 and the register 45 - the operator console 55, the node 7, the drivers 13 and 14, and the trigger 25 - the block. 56 comparison, and the keys 24., 2о, 38, .40 and 48, triggers 27, 39 and 49, elements 28, 29 and 53 - the distributor 57 pulses. The device works as follows .. At the commands of node 1 test messages from node 2 in series transferred to node 3, from where they go to node 4 and are read from node 51 by node 7. As a test message, there can be a sequence of any characters: numbers, letters, vectors, geometric figures, etc., as well as any combination of U ., r, r 1 qi, limited to signs. and End. The operator under test visually reads from the node 4 the proposed message and enters it with the help of block 5. From block 6, the entered message is received from the generator 51 to node 7, where the element message is compared with the response message. Identity of the specified messages leads to a one-time deal for the 1 st. shaper, 14 no-error signals, non-resilience triggers the Shaper of 13 signals, the presence of errors as many times as many elements have found an error. The presence of a sequence of repetitive errors indicates the presence of an OIB type of skipping or adding a sign. Taking into account the fact that the probability of double errors of the type of sign transformation is one, two orders of magnitude less than the occurrence of one-time errors of this type and is generally insignificant, the presence of double non-identities in the elements of the test-standard and input test most likely indicates the presence errors like adding or skipping a character. . The presence of such errors is detected by the trigger 25 and the key 26. Error signals from the formaker 13 are received at a single input of the trigger 25, the signals of which at the first input prepare the key 26- for operation. Repeated occurrence of the error signal causes triggering of the trigger 27. In the absence of a repetition of the error by the signal from the driver 14, the triggers 25 and 27 return to their initial state. The trigger 27 generates signals that close the keys 34 through 37 on the first inputs, and open the keys 41 and 43 on the first input. At the same time, the signals from trigger 27 through the element 53 open the key 24, thus preparing the device for detecting errors like adding a sign. To detect the badge-type skip test, the benchmark test must be shifted. in a positive direction. one character, - and to detect errors such as adding a character —in the negative direction one character. In case of errors such as missing characters, the error signal from the driver 13 through the key 26, element 29, public key 38 and element 50 is sent to the summing input of the register 47, thus changing the address of the readable signal of the reference from node 3. The signal of the element 50 through element 5-2 starts the generator 51, which generates a read pulse arriving at node 3 and block 6 for storing therein. The read signals arrive at node 7, where their identity is determined. The presence of an error in this case suggests that the most likely type of error is the addition of a sign. To detect it in this mode, it is necessary to shift the test of the standard by 2 digits in the negative direction. If there is an error like adding a mark when the test is shifted by one standard in the positive direction, the shaper 13 generates an error signal coming through the flip-flop trigger, 27 key 24 to the counting input of the flip-flop 39 which, changing its position, opens the key 40, closes the key 38 and opens the key 43 .. The signal forms the 13 via the public key 26, element 29 and the public key 40 is supplied to the generator 46, which forms two consecutive pulses fed to the subtracting input of the register 47. The last of the pair of pulses of black Generator 51 is triggered without element 52. Actual error detection of the type of transmission or supplementing characters is determined in these modes by the presence of signals from the former 14 when the shifted codes are compared. When a type error is detected, the signal skip signal shaper 14 through open signals — from triggers 27. and 39 and the signal None., Flashing from block 22, the key 4vl goes to counter 42. When an error is detected, such as adding a mark, shaper signal 14 The public key 43 passes to the counter 44. The presence of whole groups of errors associated with the omission is added or transformed with words-. Or: lines of text can usually be easily detected manually. Automatic search in this case is ineffective. In order to register the fact of detection, a block of errors in the device according to the signal of the driver 13, which passed the key 40, a trigger 49 is activated, which opens the key 48, which is reset by a signal from the driver 14-. The presence of the next error signal from the imager 13 in this mode indicates the presence of a group of errors. In this mode, the pulse of the error signal from the driver 13 through the public key 48 prokhrdit on the register 45. With this command, the data of the register 45 is read into the register 47, thereby setting the code values of the compared signals in the same state. At the same time, the signal from key 48 arrives at block 12, indicating the presence of a group of errors (gross error), the detection of which is expediently performed manually. In the process of recruiting a test message, the operator monitors its actions and, if it detects its actual error, or does not actually make a mistake (false), it corrects (edits) the message and introduces a sign that indicates a correction. The fact of the presence or absence of a correction is detected by block 22. Signal The presence of a correction from the output of block 22 pushes keys 35, 36, 41 and 43 to the input. The signal No correction from the output of block 22 prepares keys 34 and 36 of block 15 for input. Thus, from the outputs blocks 22 and 23, the counter 30 receives the number of pulses equal to the number of undetected by the operator of actual errors, the counter 31 receives the number of pulses equal to the number of actual errors detected by the operator, the counter 32 - the number of pulses equal to the number of errors but the characters entered by the operator, into the counter 33 is the number of pulses equal to the number of false errors detected by the operator, into the counter 42 is the number of pulses equal to the number of errors such as skipping signs, to the counter 44 is the number of pulses equal to the number of errors of the type adding characters. The polling signal from the output of block 23 reads the counters 30, 33, 42, and 44, which go to block 17, which also receives data from the output of counter 10 and from the output of counter 9. In block 17, the professional characteristics of the test operator are calculated , namely, the probabilities of making errors and the operator’s performance are calculated using different formulas to estimate the likelihood of simultaneous errors like transformation, for example, to estimate the likelihood of making mistakes like skip and adding characters, ki probability of error-free character input, to estimate the likelihood of error-free detection and for evaluation .oshibok operator productivity. The values of the professional characteristics of the test operator obtained as a result of the calculations are received in block 19 to calculate the operator's training indicator. - The indicator of the operator's skill in block 19 is determined taking into account incoming signals, signals and quantities. The coefficients for block 19 come from the weight setting node 21. From block 19, the values of the operator’s skill level go to block 20, to another input of which, from the imaging unit 18, the required value is received, which is determined on the basis of 21 values of weighting coefficients arriving from the node and coming from block 16. normative professional characteristics of the operator.

Thus, the invention provides operative assessments of the quality of the operator’s activity and allows one to eliminate gross errors in the assessment of the operator’s performance by taking into account errors of the type of omission and the addition of signs.

The invention improves the quality of experimental studies of the influence of engineering and psychological factors on the professional characteristics of the operator and can be used for professional selection and certification of operators, provided that there are specified standards for the professional characteristics of the operator.

It has now been established that a large number of mistakes made by operators when entering information increases the cost of solving complex economic problems by 30–40%. Countrywide, it is costly. Thus, by improving the accuracy and efficiency of monitoring the degree of preparedness of operators and their knowledge, a large economic effect is achieved.

In addition, the proposed device allows to reduce the costs, time and labor for the development of new technical means through the integrated automation of engineering and psychological research.
