SU1200322A1 - Training device for operator of information transmission feedback system - Google Patents

Description

The invention relates to the technical means of training and can mainly be used to study the logic of the information transfer systems with feedback and control the knowledge gained while taking into account the time spent on thinking of their answers by the student.

The aim of the invention is to expand the didactic capabilities of the simulator.

The drawing shows a simulator of the operator of the information transmission system with feedback.

The simulator contains a block 1 of the formation of received messages, a block 2 of simulating real processes, a block 3 for presenting educational information, a block 4 for monitoring the reliability of transmitted messages, a block 5 for simulating real processes, a decoder 6, a counter 7, a decoder 8, - a block 9 for entering operator response actions, block 10 elements And, the switch 11 modes of operation, the counter '12, the block 13 of the display, the remote control 14, the operator, the indicators 15-18 (result, channel status, evaluation and the number of errors, respectively), the driver 19 time intervals and the counter 20.

The decoder 6 is a node that, depending on the nature and combination of signals at the input, generates a signal on one of its buses, the total number of which corresponds to the number of possible errors in the operation of systems with feedback.

Counter 7 is a standard step finder, controlled by the supply of electrical pulses to its control input. The contact group corresponding to a specific position of the step finder determines the type of errors in the system channels. The decoder 8 analyzes the current state of the counter 7 and, depending on this, outputs on one of its buses a signal corresponding to a given error in the operation of the system.

Block 9 is a set of buttons, the number of which corresponds to possible errors in the operation of the system.

Using the buttons, the operator enters into the device the results of determining the type of error. Block 10 represents a multi-input coincidence circuit, the signal on the first and second outputs of which appears when the signals on the same buses of the first, second and third inputs coincide, and on the second and fourth outputs - if these signals do not match * Counter 12 provides counting of the number of errors made by the operator .

Indicators 15-18 are a combination of the scoreboard, which displays the number of errors, the assessment of the student’s knowledge and skills, the result of his actions and the direction of further work, as well as setting the student as a set of errors that correspond to different channels of the information transmission system.

The simulator operates as follows.

After the simulator is turned on and the switch 11 is set to the “Tutor” position, the counter 7 is reset, which corresponds to the first task. When this task is taught to the student in the form of an indication of the type of errors in the various channels of the system is displayed on the indicator 16, and the signals corresponding to these errors are sent to the decoder 8, which outputs a signal on one of the buses of the second input of the block 10.

In accordance with the task, the learner establishes the intended result of channel operation with the help of controls on blocks 2 and 5 and enters his answer about the expected result of the functioning of the entire system using buttons of block 9, which connect the voltage to one of the inputs of block 10. Position of the controls of blocks 2 and 5 are analyzed with the help of a decoder 6, which, in turn, depending on the position of the controls, generates a signal on one of its output buses arriving at the input of unit 10. If the signal coincides On the buses of the inputs of the block 10 of the same name, a coincidence signal is generated, which is fed to the input of block 13 to turn on the "Result is correct" display, perform the following task, and through switch 11 to the control input of counter 7 to show the next task to the learner. on the corresponding input buses of block 10, which corresponds to the error admitted by the student or in actions,

or in response, block 10 generates signals that respectively arrive at block 13, where the "Error - repeat task" board lights up, and to the input of switch 11, which 5 is not connected in the "Tutor" mode.

When performing all tasks determined by the number of contact groups of counters 7, the learner sets the “Examiner” mode. In this case, the counter 7 is reset and the learner is presented with the task. The trainee’s actions and interaction of the 15 elements of the simulator until the output signals appear Block 10 is the same as in the "Tutor" mode.

Next, the simulator works as follows. 20

The coincidence signal from one output of the block 10 enters through the switch 11 into the counter 7 and sets

the next task, and from the other exit - to block 13, where the "Result is correct scoreboard lights up, follow the next task". The signal mismatch from the output of block 10 through the switch 11 sets the counter 7 to the next state and simultaneously enters the counter 12. During the test of the student’s knowledge, the number of errors is calculated and indicated by block 13. G /

At the moment of setting the switch .. 11 to the “Exam” position, a signal from its output starts the formation timer 19. The time signals from its output go to the counting input of counter 20. The same input also receives error signals from the output of switch 11. As a result, the readings of counter 20 will be determined by the sum of the number of errors and time spent, which determines the readings of indicator 17.
