I The invention relates to an expositive technique and can be used in organizations that train and train specialists in various technical means.

The aim of the invention is to increase the speed of the device with increased learning efficiency and 1 shortening of the training time, i The drawing shows the structural scheme of the proposed device,: The device contains decoders: 1 and 2, inverters 3 and 4, element 5 of the driver of 6 pulses and blocks 7 | fault memory.

As a study object, the pa: oi: ode device can use: with any computer with self-diagnostics of failures, as well as any technical devices of electronic computing MamiH.

 As a driver, input signals for a device can be used: 3 Any micro or personal computer, for example, a CM1800 microcomputer, can be used.

The outputs of the device are connected by means of outboard mounting to the control points of the circuits of the device under study, in which it is supposed to reconstruct the malfunctions. At the input, the device is connected to the microcomputer using a loop.

 Using the device, it is also possible to simulate static and dynamic faults. To do this, relays, inverters, RC circuits must be installed in the circuit of the outputs of blocks 7, which will allow simulating faults such as breaks, faults due to changes in the frequency of occurrence of changes in shape and parameters pulses of the main signals of the device and

etc.

The device is connected to the microcomputer instead of the printing device, so the fault is simulated by the operator PRINT as follows.

PRINT d (letter ,, malfunction code) d.

The first d character allows the installation of a trigger for driver 6, which permits the operation of dep-gfratora 1.

The letter specifying the malfunction code is cleared by the GPU 2 and sets one of the blocks 7 to the state corresponding to a common fault.

The second d symbol allows resetting the trigger of the forcing unit 6, due to which the simulated malfunction persists until the next submission by the operator PRINT (i.e., prior to the start of the next follow-up (malfunction to it).

Thus, it is possible to imitate 48 faults in one device.

If the microcomputer controls the operation of several simulators, on these simulators of the device, these devices are connected, connected via a loop in series with the microcomputer. But in this case, each of the devices has its own resolution scheme, controlled by its own symbol.

The operation of the simulator under the control of a computer is carried out with the help of a program written in BASIC and realizing the functions of entering faults, monitoring the correctness of answers, issuing prompts, etc.

The program is recorded on a floppy disk. If the microcomputer controls the operation of several simulators, then on the same floppy disk several more programs are recorded under the same name, which allows, if necessary, to turn from one program to another.

The device in the practical training of specialists in technical means of a computer works as follows.

The teacher (operator), before the start of the lesson, switches on the microcomputer and loads the program. After all the required ".gx actions (the initial fault number is set by the teacher), the fault number is displayed on the display screen, and the fault is entered into the device. Trainees troubleshoot. After detecting a malfunction, the trainees on the keyboard of the display dial the answer (contact TEC), for example, 1C38PT41.

If the answer is correct, the microcomputer automatically sets the number of the next fault. If the answer is incorrect, trainees can use the hint (if they need it). If the prompt is not needed, the trainees continue troubleshooting and then enter the answer.

The trainees are given the opportunity to answer at least 3 times.

After the fourth incorrect response to the display of the microcomputer, the following message appears: Invite the teacher.

The teacher advises trainees on finding this fault and sets the number of the next fault. Training continues.

After studying all the proposed typical faults in a set time interval, students should have the necessary level of training.

The use of the proposed device allows to increase the effectiveness of the training of specialists, to reduce the training time due to more intensive conducting of exercises simultaneously on several simulators controlled by one microcomputer, interactive insertion and troubleshooting, and also due to the release of teachers transferred to the microcomputer).
