The invention relates to automation and computing and can be used in devices for training and training operators in the skills of repairing electronic equipment.

The aim of the invention is to improve the accuracy of training.

The drawing shows a block diagram of the device.

The device contains a teacher 1 console, an operator console 2 consisting of interchangeable modules 3, each of which has an output 4 encoding and an output 5 of the response signal of the operator, block 6 of the instruction for the training program, shifting registers 7, including bits 8-10, block 11 estimates, the decoder 12, the group of elements And 13, the first element OR 14, the element 15 delay, block 16 management information shredom containing the second element OR 17 and the trigger 18.

The device works as follows.

Before starting work, the teacher introduces the faulty module 3 into the remote control 2. Then, the signal from the remote control 1 from the output 4 of the faulty module 3 generates a fault coding signal to the corresponding input of block 6. When the specified input of block 6 is excited, parallel symptom codes are generated in it (for example numbers) of modules 3, which are covered by the functional indication of a faulty module 3. These codes, through the output groups of block 6, are fed to the inputs of the same-named bits 8-10 of the ring shift registers 7. Each set is one oimennyh bit register rows form a register, which stores the code of one module 3 and the placement of modules 3 bit codes in rows 8-10 corresponds to the optimal sequence of their replacement when troubleshooting. In this case, in the last bits of 9, the code of module 3 is placed, which should be replaced by the first, and in the first bits of 10, the code of module 3, which should be replaced by the last. From the outputs of the last bits 9, the code of the module 3, replaced by the first, goes to the decoder 12. At the same time, the signal from the corresponding output of the decoder 12 generates a signal to one of the inputs of the corresponding element 13. At the same time, unit 6 outputs the code of the number corresponding to the number of modules 3 to be replaced when determining a faulty module 3.

In the process of performing the task, the operator on the console 2 detects the functional symptoms of the malfunction introduced by the teacher, determines the set of modules 3 that support replacement, and the optimal sequence of their replacement. When replacing the first module 3, a corresponding signal is generated at the output 5 of the response of the console 2. This signal enters the input of the corresponding element 13. If the operator correctly identified the sequence of module replacement 3 and the first module 3 replaced by it corresponds to module 3 replaced by the first in the optimal troubleshooting, the inputs of the element 13 match the signals from the output of the decoder 12 and from the output 5 of the console 2. At the same time, the specified element 13 opens and issues a match signal to the block 11, as well as to the first inputs b locale 16, in which the signal through the element OR 17 switches the trigger 18 to one state, which forms the leading edge

5 register shift pulses 7. A falling edge is formed by the same signal from output 5 of console 2 through the element OR 14 and element 15, the delay time of which determines the duration of the shift pulse. The generated pulse shifts the program in registers 7. At the same time, the codes of modules 3, written in the same bits of 8-10, are shifted to subsequent bits, for example, from bits 10 to bits 8 and so on. After the shift in bits 9 by 5, the code of module 3 is located, which must be replaced by the second one. This code is also converted in the decoder 12 and prepares the corresponding element 13 for opening. In the case of an incorrect replacement of module 3, the signal does not match the element 13 and the shift pulse is not generated. So, the shift of the program in registers 7 does not occur. When the operator replaces the next module 3, the process is repeated. In the process of troubleshooting, block 11 receives signals of the number of modules 3 replaced by the operator from the output of element 15, signals of the sequence of replacing modules 3 from the outputs of elements 13 and the code of the optimal number of modules 3 being replaced from the group of outputs of block 6. These signals are analyzed in block 11 according to established criteria, and a corresponding assessment is given to the remote control 1.

Managing the shift of the ring shift registers improves the accuracy of training, which, in turn, contributes to the shortening of the time for finding a fault.
