The invention relates to automation and computing, in particular to devices for training operators, and can be used in various industries in training operators to troubleshoot equipment. Known simulator containing the operator's console, made in the form of interchangeable modules, sensors for malfunctions and the presence of modules, the time master unit, the evaluation unit and the remote teacher 1.

However, this device has a low accuracy of training, since the criterion for evaluating the work of the operator does not take into account which modules are covered by the functional signs of failure.

The closest to the invention is a simulator containing a teacher’s console connected to an evaluation unit, a time task unit and an operator’s console, and a program setting unit, control register, AND, OR elements, delay elements, plug-in modules, response input sensors 2. However the device does not allow to distinguish operator errors different in the degree of coarseness. So, the device does not distinguish such errors as: the defective module is replaced by a faulty module; irreplaceable serviceable entering the search zone. In addition, this device does not fix the module re-change, as this will restore the state of the control register. These drawbacks reduce the accuracy of the training device.

The aim of the invention is to increase the accuracy of the simulator.

This goal is achieved by the fact that the simulator operators of electronic equipment, containing the operator’s console and sequentially included training program assignment block, evaluation unit, teacher instructor and time job block, the output of which is connected to the second input of the evaluation unit, the first console output is connected to the console operator entered the driver of the fault codes, the first input of which is connected to the first output of the operator’s console, the second input - to the second output of the teacher’s console, and the output - to the input of the control panel Single specifying courses and with a third input of the evaluation unit and a memory unit operator actions, the first input of which is connected to the second output of the operator panel, the second input - to the second output of the remote lecturer, and an output - to a fourth input of the memory unit.

In addition, the evaluation unit contains a group of decoders, a group of adders, an adder and a functional converter whose input is the second input of the block, and the output of which is connected to the first input of the adder, the second input of which through the group adders is connected to the corresponding outputs of the group decoders, first, second and third inputs of which

are the first, third and fourth inputs of the block respectively.

FIG. 1 shows a structural diagram of the simulator; in fig. 2-5 - structural

circuits included in the simulator blocks.

The simulator of electronic equipment operators contains the operator’s console 1, states of replaceable modules 2 connected to fault coding sensors 3 and answers input sensors 4, teacher’s console 5 connected to evaluation unit 6, time task unit 7 and operator’s console 1, task unit 8 training program, driver 9 fault codes connected to the outputs of sensors 3, coding faults of operator’s console 1, block 10 of operator’s actions memory (for module replacement) connected to outputs of sensors 4 input of answers n Ulta 1 operator.

Sensor 3 (FIG. 2) is

0 pin connector into which plug-in module 2 is inserted. In this case, a polling signal from the console 5 through one input contact of this connector enters module 2. If module 2 is faulty, but has a jumper between the remote control with this input contact and one of the output type malfunction. In the simplest case, the sensor 3 has one output contact, which provides a signal transfer to the driver 9 about the failure of module 2 without specifying its type. Serviceable module 2 jumper does not have. Jumpers are inside modules 2 and hidden from the operator.

Sensor 4 is a node that provides a signal every time a module is replaced. For example, this is an inspectionally connected contact group 11 (Fig. 2), on which the interchangeable module 2, the trigger 12 and the pulse shaper 13 (for example, a differentiating chain) act mechanically through the pusher.

Shaper 9 and block 10 can be

performed on trigger registers, such as JK or T flip-flops, with initial state setting circuits.

Block 8 is a converter of the codes of the input signals into the codes of the output signals according to a predetermined correspondence table. This table takes into account which modules may be faulty with the same external manifestations that are obtained from a certain type of malfunction of this module, i.e. which modules are included in the functional zone of a given type of fault. In accordance with this, the software module is made in the form of K elements OR 14 (Fig. 3), where K is the number of replaceable

5 modules 2, each input of block 8 is connected to one of the inputs of those elements OR 14, the numbers of which are included in the fault zone of this type, and the outputs

the elements of OR 14 are the outputs of block 8.

Block 6 (FIG. 4) consists of three-input decoders 15, adders 16 and 17, and a functional converter 18, for example, a scale element in the form of a potentiometer or an analog-type diode functional converter.

Block 7 is a node that provides signals, the value (or code) of which is proportional to the required 1 st time.

The console 5 (FIG. 5) has a node 19 for outputting a signal of the initial installation, a node 20 for issuing a start signal of unit 7 and console 1, and a recording device 21, for example, a voltmeter calibrated in percentage or conventional units.

The simulator of radio-electronic equipment operators works as follows.

Before starting work, the teacher enters into the simulator malfunctions by installing faulty modules 2, turns on the simulator and zeroing from the console 5 the registers of the former 9 and block 10 using the node 19. Then the teacher issues the task to the trained operator, starts from the console 5 using the node 20 and sends a start signal to console 1. This signal from sensors 3 records information about the initial malfunctions of the device under study in the register of the former 9. Unit 7 begins to count the control time of the fault search, taken into account and evaluation of operator actions. After the information is entered into the register of block 10, the information at the output of block 8 appears in the form of signals at the outputs of the elements OR 14 corresponding to the search area modules.

During the execution of the task on the simulator, the operator detects the functional symptoms of the malfunction, determines which modules may be faulty, successively replaces them with serviceable ones, and after each replacement checks for the presence of functional symptoms of the malfunctions. With each replacement of module 2, the contact group And is triggered, the trigger 12 changes its state and the driver 13 issues

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

Unit 6 monitors the state of unit 10 and, taking into account information from the imaging unit 9, unit 8 and unit 7, produces an estimate of the actions of the operator and outputs it to the console 5.

The block 6 with the help of the decoders 15 distinguishes the following states of the replaceable modules 2 and the actions of the learner;

faulty module replaced;

faulty module not replaced;

serviceable, but the module included in the search zone is replaced;

the serviceable, but incoming, module is not replaced in the search zone;

the serviceable module that is not included in the search zone has been replaced:

A serviceable module that is not in the search zone is not replaced.

Since these states are mutually exclusive-. In other words, at the output of each decoder 15, only one signal is produced, which is equal to a logical one. Simultaneous signals with a given coefficient are summed at the same adders 16. The final estimate value is obtained by summing up with the specified coefficients of the outputs of the adders 16 and the converter 18 at the output adder 17. At the same time, the converter 18 produces a signal associated with a certain dependence on the operator’s working time, which is set during tuning. simulator.

Thus, the proposed technical solution makes it possible to distinguish the listed six different actions of the student with each medal, whereas in the prototype such various rude errors are identified as "the module module was not replaced, i.e. fault detection, and “is irreplaceable for a serviceable module entering the search zone, and also for replacing a serviceable one that is not in the search zone. In the prototype, such a situation is not fixed when the module is replaced twice. Thus, according to the number of distinguished situations, the proposed simulator 3 times more accurately evaluates the effects of a trainer compared to the prototype.
