Invented relates to the technical means of practical training of operators of ACS and can be used in simulators for training operators of control systems.

The purpose of the invention is the expansion of didactic opportunities.

The constant target is achieved by the fact that the device for training the operator, containing the address register, whose setup input is the device input, and the information outputs are connected to the corresponding address inputs of the microprogram memory unit, the outputs of which are connected to the corresponding information inputs of the microcommand register, which outputs Zany with information boards, the first and second counters, connected decoders and indicators, generator, additionally contains the first and second group of elements And, the outputs connected to the inputs of the corresponding decoders, and the first inputs to the outputs of the corresponding counters, the setup inputs of which are connected to the device start input and the clock generator, the stop input of which

connected to the overflow output of the address register and the second inputs of the elements of the first and second groups, the counting inputs of the first and second counters are connected respectively to the first and second outputs of the response panel.

The drawing shows a block diagram of the device.

The device contains a register of 1 microcommand address, a microprogram memory block 2, a microcommand register 3, a display 4, an operator console 5, a first 6 counter, a second 7 counter, a first 8 and a second. 9 group of elements And, the first 10 and second 11 decoders, the first 12 and second 13 indicators, the generator 14 clock pulses.

In addition, the external input 16 of the register 1 of the micro-command address for entering the error addresses and the external input 16 of the start of the learning device are indicated.

The essence of the proposed invention is to increase the level of preparedness of the operator due to his training in the final stages of recognizing situations arising due to erroneous actions of the operator. Moreover, such errors can be typical for each

a separate algorithm and the operator can allow them in the subsequent independent activities, despite the fact that he did not make them in the process of preparation. And, of course, he must promptly detect errors that may lead to the non-fulfillment of a control task or an accident.

Methodically, the use of the proposed device is most appropriate after the operator has developed the necessary skills with the required quality, i.e. after the stage of formation of reproductive thinking and the transition to the stage of formation of productive thinking.

Register 1 of the microcommand address is intended to specify the control component of the operator's activity algorithm. It contains as many cells as there are elementary operations in the control algorithm, plus one more to indicate the end of the algorithm. When a signal appears at the trigger input, the address of the first command is read into block 2 of the microprogram memory. The second input of the address register is intended for reading the addresses of subsequent micro-operations. When a signal arrives at it, the next cell is shifted and the address of the next microcommand from block 2 of the microprogram memory is read. The outputs of address register 1 are associated with a firmware memory block.

The external inputs 15 of block 1 are designed to define addresses of operations that are performed with errors and for which the corresponding states of the information board 4 are set.

The memory unit 2 serves to store, as microcommands, the data of each operation of the control algorithm and possible errors. When signals appear at the inputs of the memory block 2, the microcommand of the current operation of the algorithm is read into the register 3. microcommand. In addition, data about erroneous operations, i.e. the code of the wrongly involved board organ and the corresponding state of the board 4.

Register 3 microcommands is designed to store the data of the current (processed) operation of the algorithms. This register contains two microoperations: the first one contains the code of the display indication body 4, which changes its state in this operation of the algorithm, and the second code of the control panel 5, which the operator must influence in the same operation of the activity algorithm. From the first outputs of the register 3 microcommands the required code

organ display is fed to the input of the board 4,

In the proposed mode of use, the device for this register is sufficient

one - the first micro-operation,

Table 4 and console 5 are the physical model of the operator console of the real ACS. In this case, the console 5 may contain only two buttons for issuing signals by the operator: Correct and Incorrect, i.e. Error in the demonstrated algorithm, respectively. In another embodiment, these buttons can be mounted for the remote control of the simulator.

5 The first 6 and second 7 counters are intended to count the number of control algorithm operations recognized to be executed erroneously and accurately, respectively.

The first 8 and the second 9 groups of elements And

0 perform the functions of the switching elements.

The first decoder 10 and the indicator 12, the second decoder 11 and the indicator 13 serve to display the contents of the first

5 6 and second 7 counters.

The generator 14 clock pulses is designed to control the change of information on the board 4 in the mode of demonstration of the algorithm to the student. Pulse frequency

A generator 0 is set individually by each trainee.

The device operates as follows

With the simulator turned on due to the signal booster at input 16 of the device, the command goes to the setup inputs of the first 6 and second 7 counters for their training. The same signal is fed to the setup input of the register 1 address, in which

0 previously entered addresses of erroneous operations to the inputs 15. In addition, the incoming signal triggers the generator 14 clock pulses, which arrive at the shift input of register 1, which leads

5 to read the microcommand address in the microprogram memory block 2 corresponding to the first operation of the control algorithm.

The microcommand selected in block 2 of the memory is rewritten into register 3 of microcommands and, at its first inputs, is fed to information board 4, where the required organ changes its state. The second outputs receive the organ code of the console 5, which is activated by the operator. This control unit 5 lights up. In this case, the student analyzes the correctness of the operator's actions. If he believes that the operation has been carried out correctly, he presses one button and the signal appears on the first

console output 5. It enters the counting input of the first counter 6 for counting. In the event that the learner finds that the operator made a mistake in the algorithm he demonstrated, he activates the second button and the signal appears on the first output of the board 5 and is fed to the second counter 7 for counting.

After the address register issues a signal from its overflow output, i.e. after completion of the algorithm, generator 14 is turned off and elements of the first 8 and second 9 groups open. The contents of the counters are fed to the corresponding indicators 12 and 13 for display.

An indicator of the level of preparedness of an operator here is the degree of correspondence of the contents of the counters and the actual number of errors entered into the address register 1.

The proposed device expands the didactic possibilities by forming productive thinking in the student and increases the efficiency of the learning process for the elements of situational management.

The device makes it possible to reproduce situations of the occurrence of various accidents and malfunctions and to form the ability of the trainees to analyze the actions of the colleague-operator who allowed them, which is especially important for the activities of responsible production operators, such as nuclear power plants.
