The invention relates to computerized automation, in particular simulators, and can be used for professional training in diagnostics and troubleshooting skills of computer aids.

The purpose of the invention is to expand the didactic capabilities of the training device.

Figure 1 shows the block diagram of the device; figure 2 - structural diagram of the pulse generator.

The training device (Fig. 1) contains the Start and Input input buses, T generators and 2 pulses, Fault Simulation Unit 3, Response Block 4, Memory Block 5, OR 6 Element, First and Second Comparison Blocks 7 and 8, Block 9 indications, element 10, the driver of 11 pulses, the generator of 12 clock pulses, the meter 13, the block 14 registration.

The registration unit 14 comprises a memory block T 5 and an indicator 16.

The shaper 11 pulses (figure 2) contains the element OR 17, the first and second one-shot 18, 19, the first to the second trigger 20, 21, the element And 2j2 and the counter 23.

The device works as follows.

In the initial state, the generator 12 generates clock pulses that arrive at the clock input of the driver 11 pulses, the counters 13, 23, and the device triggers 20, 21 are reset.

When a Start signal appears, the generator 1 generates a code that is recorded in block 3 of the simulation of faults, which leads to the imitation of the malfunction of the diagnosed equipment. After determining the nature of the malfunction, the learner enters from the response input block 4 a code unambiguously characterizing, for example, a missing or incorrectly generated signal that goes to the first address input of block 5. The data retrieval area from block 5 is set by the higher bits of its address bus, connected to If the output code of unit 5 coincides with the output information of generator 1, which may occur when the malfunction is accurately determined, then when an input signal appears, confirming the presence of a response, At the output of the comparator unit 7, a signal is generated, which leads to highlighting of the relevant information on the display of the display unit 9, resetting the pulse generator 11 and blanking the indicator 16. Otherwise, the output information of the one-shot 18 records the setting information to the counter 23, and the output one-shot 19 pulse generator 11 is triggered. The output pulses of the imaging unit 11 through the element OR 6 arrive at the clock input of generator 2, the initial state of the register of which is set by generator 1. The output information of generator 2 is compared in block 8 of comparison with the output code of block 5. Each state of generator 2 changing under the action of clock pulses, uniquely corresponds to elements (signals for a reducible case) combined into one common search area by any signs (for example, control signals, data bus bits or microprocessor address bus systems). The number of these elements in each zone may not be identical and is set by presetting counter 23. If, after passing a predetermined number of pulses, the codes in block 8 do not match, a pulse is generated at the overflow output of counter 23, which resets trigger 20. In this case, the output of block 15 appears information causing the display on the indicator 16 of the message on the incorrect determination of the nature of the Fault.

If at some point the codes in block 8 match, the element 10 is locked, the output state of the counter 13, which arrives at the first address input of the block 15, the higher bits of which are also controlled by the generator 1, will cause the display to indicate the degree distance of the student’s response from the correct one.

The next Input signal accompanying the student's response is reset of the counter 13, then the device operates according to the indicated algorithm.

In the present invention, a prompting mode is provided that gradually brings the learner closer to the correct answer, which facilitates the search for malfunctions and assimilation of diagnostic skills, and consequently, expands the didactic capabilities of the training device.
