this input contact and one of the output, corresponding to the type of malfunction. In the case of the sensor 3, the sensor has one output contact, providing a signal transfer to the driver 9 about the fact of the failure of module 2 without specifying its type. Serviceable NfoAynb 2 does not have jumpers. Jumpers are inside modules 2 and hidden from the operator.

The teacher’s console 15 (FIG. 5) contains a signal output unit 20, a start-up of the time setting unit 17 and a query signal output signal of the sensor 3, and also a recording device 21, for example a voltmeter.

Sensor 4 is a node that provides a signal every time a module is replaced. For example, this is a series-connected contact group 22 (FIG. 2), on which a separate module 2, a trigger 23, and a pulse shaper 24 (for example, a differentiating circuit) act on the fexanchram pusher,.

The evaluation unit 16 (FIG. 3) consists of three-input decoders 25, adders 26 and 27, and a functional converter 28, for example, a large-scale element in the form of a potentiometer or an analog-type diode functional converter.

The diagnostic program code setting node 5 (Fig. 6) is a serially connected switching authority 29 of the diagnostic program code, the encoder 30, and the initial address register 31. The entry of the initial address in this register and the issuance from it to the counter 11 (the address occurs on a signal from Wela 7 of the initial start signal.

Nodes 6 and 7 of the initial setup and initial start-up signals are successively connected switching organs (button, toggle switch, key, etc.,) tripler, pulse shaper (for example, a differentiating circuit). And hardware can be implemented similarly to sensor 4 of input answers (Fig. 2),

The display unit 8 consists of a set of information fields on which the configuration states of the models and the functional prizes are indicated (for example, by LEDs, incandescent lamps, dial gauges, etc.).

troubles. The information for - mapping to the display unit 8 is entered from the corresponding bits of the register 12,

The counter 11 (addresses) can be executed on the account of the shakh 32 with pre-setting the address of the diagnostic program, the counting input and the installation input of the initial state (Fig. 4). Moreover, the pre-installation input is connected to the output of the OR circuit 33, which receives signals from the node 7 for issuing the initial start signal and the comparison circuit 19.

The generator 13 counting pulses (Fig, 7) contains the element OR 34, thrunger 35 and the multivibrator 36,

The program 14 for setting learning programs is a programmable permanent locking device (PIZU) in which a set of constants is recorded that simulate the progress of a diagnostic program on an indication 8. The structure of the constant read from the instruction set 14 of the training program (FIG. 8) contains (S-1) bits.

The time setting unit 17 is a node that provides for the output of signals whose magnitude (or code) is proportional to the required time range.

The simulator of the operator of digital computer complexes works as follows.

In the initial state, the driver 9, block 10, the counter II and the register 12 are zeroed, the trigger 35 of the generator 13 is in the zero state,

The simulator has two modes of operation: control of the simulator's equipment on test programs and operator training for localization and troubleshooting,

In the test mode of the simulator's equipment on test programs, the teacher enters malfunctions into the simulator by installing faulty modules 2, while the teacher’s console 15 does not provide interrogation signals of the fault coding sensors 3 and the signal to the time task unit 17. Then the teacher issues a task to the trained operator to check certain groups of PPM modules. The operator on the switching unit 29 of node 5 dials the diagnostic program code that checks the specified group of modules.

According to the start-up signal from node 7, the code of the selected diagnostic program from the switching authorities of node 5 is converted by the encoder 30 into the starting address, entered into the register 31 of the starting address of node 5, and written to the counter And (addresses). In this case, with the driver 9 in the counter 11

The transmitter from the console 15 with the node 20 outputs a signal for polling the sensors 3, according to which information about the initial malfunctions of the module under study is entered into the register of the imaging unit 9. With the same signal, the time setting unit 17 is started and the test time reference for the fault finding begins

the zero code is recorded, since it is taken into account when evaluating the de-resolution of polling sensors 3 from the operator's bulletins. When the codes coincide, the 15 teachers in the comparison block 19 produce

By the signal Initial start-up, the RS-trig signal, by which the generator 35 is locked, the generator 13 is translated into writing the contents of the register 31 and the starting state, thereby allowing -15 ° the address of the node 5 and the driver 9.

The formation of a +1 signal ensures the natural ordering of the formation of constant addresses by a counter 1 1

At the address from counter 11, the first constant from block 14 is sampled and written to the register on the 12th day by the signal from the generator 13 delayed by the delay element 18 at the time of retrieving information from the CTU. The bits 25 of the register of the 12th number lead to a junction from O to n and are received at block 19 as compared to the RS flip-flop 35 of the generator 13 at zero, where they are compared with the contents of the register 31 of the initial address of the node 5, Bit with (n + I ) k arrives from the register of the 12th number at the node located in the evaluation unit 16, contain 8 indications of the operator’s console 1, imi-information about the modules included in the area of the diagnostic program run and indication on the display elements module status. At the same time, O. is recorded in the bits that carry information about the functional signs of a malfunction. At the same time, the generator of the 13 pulses does not stop, thereby providing the dynamics of the passage of DNA to the group 22, the trigger 23 changes its spinning program. The instructor and the driver 24 issues on the display unit 8 the practical skills of the trainee on the launch of diagnostic programs and the ability to evaluate the results of their implementation. This mode of operation checks the main equipment of the simulator and allows us to conclude that the operator's localization and troubleshooting training will be carried out on a working simulator.

into the address counter 11, in this case the constant is sampled from the EPROM, the bits of which on the node 8 of the console 1 indicate functional, fault symptoms characteristic of this type of modules. Different groups of functional symptoms of faults are set by jumpers in the replaceable module 2. Occurrence (t + 1) of discharge

Block 16 monitors the state of block 10 and, taking into account the information from fortovatch 9, bits c (t + 2) through s of register 12 and block 17, produces an estimate of the operator's actions and outputs it to the console 15.

Block 16 using the decoder 25 distinguishes between the following states of plug-in modules 2 and the actions of the learner:

The fault malfunction is performed as follows.

The teacher issues the task to the student and the operator begins to work as well as in the mode of testing the equipment of the simulator on the test programs. The difference is that the register number of 12 leads to a jerk of the RS-flip-flop 35 of the generator 13 in the zero in block 16 of the assessment, contain information about the modules included in the zone for group 22, the flip-flop 23 changes its state and driver 24 gives out

register number 12 leads to dropping the RS flip-flop 35 of the generator 13 in zero in the evaluation unit 16, contain information about the modules included in the zone for group 22, the trigger 23 changes its state and the driver 24 issues

The new state, thereby, the formation of the +1 signal by the multivibrator 36 is stopped. The bits c (t + 2) through s, 20 after the 25 register of the 12th number lead to the dropping of the RS flip-flop 35 of the generator 13 in the zero box in the estimator 16, contain information about the modules included in zone d per group 22, trigger 23 changes its status and driver 24 issues

signal. Thus, from sensor 4 to block 10, a signal arrives and records the fact of this replacement.

Block 16 monitors the state of block 10 and, taking into account the information from fortovatch 9, bits c (t + 2) through s of register 12 and block 17, produces an estimate of the operator's actions and outputs it to the console 15.

Block 16 using the decoder 25 distinguishes between the following states of plug-in modules 2 and the actions of the learner:

faulty module replaced; faulty module not replaced; serviceable, but entering the module in the search area has been replaced; faulty, but the module included in the search zone is not replaced; healthy module not included in the search zone

replaced; A healthy module that is not part of the search zone is not interrupted.

Since these states are mutually exclusive, the output of each decoder 25 produces only one signal, equal to the logical one. Simultaneous signals with a given coefficient (1a1c are summed on the same adders 26. The value of the estimate is obtained by summing with the given output coefficients of the adders 26 and the converter 28 on the output adder 27. In this case, the converter 28 produces a signal associated with some dependence on the operation time operator installed when setting up the simulator.
