(54) TRAINING DEVICE

The invention relates to the field of automation and computer technology and can be used in educational institutions for teaching various educational disciplines.

A teaching device is known that contains student and teacher consoles, information carriers, a projector, a control unit and a registration unit 1.

However, the device has a low speed, the information retrieval system in it is complex and the amount of information is limited.

The closest technical solution to the invention is a training device comprising a series-connected ring switch, a response input block, a decryptor, a program setting block and an information analysis block connected to a ring switch and an estimator block, an information presentation unit | Marcia connected to the control block 2

This device has a sufficient amount of information, but its speed is limited, which reduces the effectiveness of its use.

The aim of the invention is to improve the speed of the device.

This goal is achieved by the fact that the proposed device contains a block for coding the area of educational information, a block for determining the search direction, and a reverse

A new counter connected to the output of the information presentation block, the first input of the search direction determination block, the second input of which is connected to the output of the information analysis block through the coding block of the training information area. The input of the control unit is connected to the output of the search direction determining unit.

The drawing shows a block diagram of the device.

It contains a series-connected ring switch 1, a response input block 2, a decoder 3, a program setting block 4 and an information analysis block 5 connected to the switch 1 and the evaluation block 6, an information presentation block 7 connected to the control block 8, a reverse switch 9, connected to the output of the block 7 and the first input of the block for determining the direction of the search 10, the second input of which is connected to the output of the information analysis block 5 through the coding block of the training information 11 to the output of the definition block dividing the search direction 10.

The training device operates as follows.

The teacher turns on the device by pre-coding the training program in block 4. The student displays information on the screen that is designed from the information carrier of block 7. After studying the information, the student enters the response code using the response input block 2. Analysis block 5 analyzes the response using signals coming from the switch 1 and from the input block of answers 2 through descrambler 3 and the program setting block 4. The analysis block 5 sends signals to the evaluation block 6 and the coding block of the training information 11 for submission to the binary code with the decimal code search command the necessary information unit 10.

The search direction determining unit 10 is a resistive voltage divider with keys on magnetically controlled contacts (mechanical or photoelectric design). The unit 10 provides positive, negative potentials or zero to the input of the control unit 8, which is an electronic polarized relay, which connects the reversible motor of the unit 7 to the required direction of rotation and turns off the projection system. The drum rewind shaft of the projection unit is rigidly connected to the shaft of the mechanical reversible decimal meter 9, the disk of each bit of the counter rotates the magnet, which in the process of searching (rotating) closes the magnetic-controlled contacts (keys) of the corresponding bit (not shown).

If, in block 10, the voltage of the position established by the first digit coincides

counter 9 (i.e., a magnetically controlled contact) in block 10 and the position specified by block 11 and corresponding to the units of the installed code, block 10 outputs a potential O about to the input of control unit 8, which puts the controlled motor into a braking mode and turns on the projection system .

The speed of the device is increased by increasing the speed of searching and presenting information.
