However, the known device does not allow operators to be trained in the functional control of complex ACS, which reduces the didactic capabilities of the device.

The aim of the invention is to expand the didactic capabilities of the device due to the automatic

The delivered tel is achieved by the fact that in a device containing a series-connected operator response input unit, a comparison unit, an element and a first counter, a sensor unit connected in series, an amplifier, an operator's optimum zone recording unit, the first shift register, a pulse shaper, and a switch, as well as a display unit, the first, second, third and fourth inputs of which are connected respectively to the output of forming pulses, the output of the element And and the first y and the second output of the block the registration of the optimal operator's zone of intensity, the output of the pulse generator is connected to the second input of the element and, sequentially connected, the first memory block, the logic block and the second memory block and the second shift register and the second counter, the second input of which is connected to the second the output of the operator input actions input unit whose third output is connected to the input of the second shift register and the second input to the second storage unit whose output is connected to the fifth input of the indicator block tion, a first switch output connected to a second input of the logic unit, and the second output to the input of the first memory unit, whose output is connected to the sixth input of the indication unit,

Moreover, the logic block contains a series-connected decoder, the AND elements, the outputs of which are the output of the block, the first and second inputs of the decoder are respectively the first and second inputs of the block.

1. shows the proposed device in figure 2 - logical block.

The proposed device (Fig. 1) contains a block 1 for inputting response actions of the operator, a block 2 for comparison (highlighting the correct answers), a switch 3, a block 4 for indication, a shaper 5 pulses (time intervals), element Ib, the first Counter 7, readout the number of operator actions correct for the specified time interval, the first shift register 8, which provides a change in the value of the specified time interval depending on the change in the intensity of the operator's actions, unit 9 of the registration of the optimal zone is stressful ty operator amplifier 10, blok11 Yes Pins (contact electrodes). Block 9 contains a generator 12, element I 13, integrator 14, Schmitt triggers 15 and 16 with an adjustable threshold for maximum and minimum. Triggers 15 and 16 are set to zero by the falling edge of pulses from generator 12. Block 4 has a matrix, gas-discharge indicator 17 of incoming codes, having internal memory of four pages of information (160 information characters on one page), a gas-discharge indicator 18 correct and timely actions, the indicator 19 for an increase in the response time and the indicator 20 for a decrease in the response time, the gateway 21, drivers 22–24 codes, information buses 25–30. The device also contains a memory block 31, a logic block 32, a memory block 33, a shift register 34, and a counter 35. Logic block 32 contains (FIG. 2) a decoder 36, elements AND 3 39 of the first group and elements 40 of the second group ., having output tires 4 45. The decoder 36 consists of a counter 46, an element And 47, an element And 48 and a counter 49. The device works as follows. Onepaifopy, using the indicators of block 4, presents the signals for which it must respond using the keys of block 1. The program of information signals is set by the switch 3, the time allotted for performing actions is set by the generator 5. The correct answers, according to which the operator is placed in the allotted time interval, are recorded by the counter 7 and are displayed on the indicator 18. At the same time, the operator does not intermittently monitor the intensity of the operator's actions by changing his electrical resistance to. and maintain the optimal level of intensity of actions in a given interval using block 9 by changing the time allotted for the response, i.e. changes in the duration of the time intervals of the driver 5 and the display of these changes by indicators 1 and 20 of increasing and decreasing the response time to stimulate the subject to enter the optimal zone. When the power is turned on, the switch 3, the triggers 16 of the block 9 and the display unit are reset. The operator, using the indicator 17, is presented with the signals of the functional control of the technical state of a complex ACS in the form of digital signals (the device was considered as an example of an eight-bit code) coming from switch 3 through block 31 and node 21. According to these codes, he must make a decision about the failure one or several nodes of a complex ACS and respond using the keys of block 1. Information on the malfunction of nodes of a complex ACS is embedded in a small number of combinations of a digital code, as well as in the meaning of the digits itself, which requires oh logical processing. Automatic processing of information from block 31 is performed by logic block 32.. Information about the malfunction of nodes of a complex ACS (consider the example of three combinations) is successively supplied from block 31 to the inputs of the decoder 36 (FIG. 2), which splits the incoming information into three lines of an eight-digit decimal digital code. The divided eight-digit decimal digital code is fed to a group of elements 37–39. On elements 39, the last eighth digit of the eight-digit digital code is allocated, on elements 38, the second-to-last seventh digit of the eight-digit digital code is selected, and on elements 37, the sixth digit is selected. These numbers arrive at AND 40s for comparison. In the case of coincidence of incoming And out of one of the elements of 40 digits, at the output we get the code of the digit received at the input. If the numbers arriving at element 1 and 40 are not equal, then there are no signals at the outputs. If information arrives at the input of the decoder 36 and the code 41 is the decimal number X, then h indicates that, in the first series of devices, device X is faulty, if X is received on the bus 43, then this indicates that in the second series of devices, device X is faulty, and if the X number on bus 42 is in the third series, device K is faulty. If the decimal Y code appears on bus 44, this indicates that the characteristic Y of device X is out of tolerance. If the bus 45 appears to be the ten code of Z, then this indicates that the node Z is faulty devices X. The malfunction signals generated by the logic unit 32 are transmitted to one input of the comparison unit 2 and to one input of the memory block 33. The other inputs of block 2 receive signals from block 1 when you press the keys. The correct answers that the operator placed in the allotted time interval are recorded by the counter 7 and displayed on the indicator 18 by means of the generator 23. In case of an incorrect answer, the operator repeats the access to the new answer or may press the button I don’t know on block 1. All operator’s actions are fixed to counter 35. When you press the button I don’t know the signal from block 1 is fed to block 33, and the information signals of logic block 32 recorded in block 33 are skipped to block 24 codes, which generate right-handed signals operator's actions on the info {zmation presented to him. Information of the correct answer of the operator from the driver of 24 codes is displayed on the indicator 18. When you press the button I do not know, the signal through the register 34 enters the counter 35, while the number of pulses corresponds to 1/5 of the pulses of calls to the new answer. Further, the operator continues to process information on new HeHc right x complex ACS. Based on the readings of counters 7 and 35, it is possible to calculate the reliability of the operator. During operation of the device, continuous monitoring of the operator’s actions is carried out. The information signals are turned on and turned on by the shaper 5, which controls the switch 3, the shaper 22, which generates a blanking signal. The use of the proposed technical solution in devices for the selection and training of functional control operators in complex automated control systems that require large psychological stresses increases the accuracy of selection, the efficiency of application of methods, reduces preparation time and reduces costs through selection and training of operators.
