Description

one

The invention relates to radio telegraph simulators and can be used as a device for training operators.

A radio telegraph simulator is known to contain: A Walsh function generator, connected to a switching and electroacoustic conversion unit, a learning console connected through a control unit to the input of a Walsh function generator and a switching and electroacoustic conversion unit l.

Claims (1)

When working with the simulator, the MO does not take into account that when perceiving the sound images of Walsh functions, the trainee can make various mistakes. These signs can be classified for reasons of their occurrence: skipping of individual signal elements, incorrect estimation of intervals between elements, adding elements, incorrect estimation of duration, . Incorrectly identified signals are attributed to the causes of errors. For example, if the Fpoie function (3.8) is presented to the learner in the Walsh-Paley function system, and he selects the function (7.8) in the Walsh-Hadamard function system, which is equal to its PpeE function (3.8) - then The reason for the error is an incorrect estimate of the spacing between the signal elements. Thus, according to the established rules, each possible identification result can be associated with a decision about the reasons for the occurrence of errors. The simulator works in the following way. Previously, according to the established rules, in the classifier 10, decisions are made about the causes of errors for each incorrect answer. The simulator operates in two modes: in mode I - presentation of the learning function of the Walsh function for storage and in mode I I - recognition of the reference function from a number of presented functions. In mode 1, the signal from control block 1 switches to the state in which the input of the memory block of the Walsh reference function is connected to the output from control block 1, the Walsh function switch 3 connects its output to the i-th (where I 1,2-16). The output of the generator 2 of the Walsh function, from which 1 is derived and the standard Walsh function, the sound image of which the student must remember. When a control signal is fed from block 1 to the input of the generator 2 of the Walsh function, the Walsh function is recorded from the I-th output of the latter through the created circuit to the memory block B of the reference Walsh function. Since the output of switch 3 is connected to an electroacoustic converter 4, the training hears a sound image of the (Walsh function). In mode II, the trainer presents a series of Walsh functions from which it must recognize the reference set before it. In this mode, the signal from the unit 1 control switch 5 connects the memory block 7 of the proposed Walsh function to the output of the switch Walsh function 3. Then, using signals from control block 1, the switch 3 connects to its j-oro output (where j 1 , 2-16). Walsh function generator 2 output. In this case, generator 2, started on command from control block 1, j-Walsh function, is entered into memory block 7 of the developed function, and again the j-function is erased by the previous j-1 function At the same time, the Walsh function arrives at the input of the electroacoustic transducer 4 and the student can perceive the sound image of this function. If he believes that the j function differs from the i-th reference function previously assigned to him, he does not press the key ( not shown in the drawing) on the remote control 12. in this case Lock 1 instructs the control switch 3 Walsh functions for which it connects to its output the next j + 1 output of the generator 2 Walsh functions. In the future, the simulator works as described above. If the student decides that; Presented to it is 1. The func- tion1 is the j-a reference function, then it presses the key on the remote control 12. At the same time, the control unit 1 turns off the generator 2 of the Walsh function and switches switches 3 and 5 to the initial state. At the same time, the signal from the output of the console 12 connects the unit 8 of the subtraction subtracting to blocks 6 and 7 of the memory of the reference and presented functions, as well as activates the classifier 10. The block 8 of the subtraction subtracting finds the difference between the i-th Walsh function recorded in the block 6 memory, and the j-th Walsh function, recorded in memory block 7. This difference enters the detector 9 signs, which generates signals containing signs of errors. The signals from the detector output 9 features are fed to the input of the classifier 10, which makes a decision about the error admitted to one of the predetermined classes (for example, skipping signal elements at the beginning, incorrect estimation of intervals between elements, etc.). The decision made by the classifier on the causes of the error is displayed on the display of the block 11 displaying the causes of the errors. The simulator then goes back to mode I, in which the training is presented (function, and all subsequent operations are repeated as described above. The simulator ends after all N (where N 8 or 16) sound images of Walsh functions are presented to the student The proposed wireless telegraph simulator increases the efficiency of a discrete-signal simulator and reduces training time.
