The essence of the claimed invention is illustrated by drawings, where:

- in FIG. 1 shows a general diagram of a training complex for a sorting slide operator;

- in FIG. 2 shows a diagram of the interaction of technical, software and methodological tools of the simulator;

- in FIG. 3 shows a layout of places in the training complex.

An example of a proposed training complex includes:

- training jobs 1, each of which is a personal computer (system unit with a monitor);

- printer 2;

- an automated workstation 3 (hereinafter referred to as the workstation) of an instructor, which is a personal computer (system unit with two monitors);

- AWP 4 and 5, respectively, of the duty officer on the hill (AWP DSPG) and operators who, through switch 6 of HP1700 (24), are connected to servers 7 and 8, respectively, of applications and speakers, by central server 9 (signaling system);

- visualization system 10 with webcams 11.

The switch is connected to a router, to which also through another switch, a visualization system is connected. The visualization system includes at least one display section controlled by a computer-generated image generation system. Also in the training complex there is at least one Web-camera.

Each console can be made in the form of a separate table with an inclined front panel and contains a light diagram of the corresponding paths, as well as a set of buttons, switches and LEDs to indicate current operating modes. To access

5

to the internal elements of the remote control, the front panel is made reclining. The front panel is locked in the open position by means of a bar.

Tables are made of chipboard 16 mm thick, the top cover to ensure higher strength is made of multilayer plywood 16 mm thick. A cut-in rubber edging 18 mm wide is installed along the edge of the top cover. Inside the table are a small-sized nettop - a computer and cable system for connecting power and connecting the panels to each other.

For ease of installation and repair and maintenance work, each remote control is assembled from several units (two or four). All switching and indication elements of the units are installed on metal panels made of D16T material with a thickness of 3 mm. The panels are painted with gray polymer paint (color 7032) and covered with false panels made of 3 mm anti-reflective plexiglass. All inscriptions and light schemes are applied on the false panels and are performed by large-format color printing. To install the blocks in the top cover of each table, the corresponding holes are made.

For mounting display and switching elements, printed wiring is used. All printed circuit boards are connected using connectors and a flexible flat ribbon cable system.

On the front panel of the remote control there are displayed all the switching and indication elements for the remote control on the slide, there is also a clip for attaching the sorting sheet.

The microprocessor control units of all the consoles are the same and differ only in the settings of the DIP switches, with which the remote control identification system is configured.

On the back wall of each remote are:

- connectors for connecting the power cable and Ethernet network cables;

- a connector for connecting a USB cable (type B);

- power fuse block (located in the power connector).

The controller block contains the following nodes:

- microprocessor unit - controls all elements of the circuit, realizing the basic functions of the device;

- CAN-interface unit - provides control and information exchange between the master and slave controllers over twisted pair;

6

- button polling unit - periodically polls the state of the buttons and, at the request of the computer, transmits to it via the serial port the codes of the pressed buttons (polling period 6 ms); the buttons are connected so that they form a matrix consisting of 16 columns and 10 rows;

- LED control unit - lights up, turns off or makes the desired LED blink when a control code is received from the computer via the USB port. LEDs are connected in a matrix consisting of 8 columns and 21 rows;

- USB module - communicates via the USB interface between the controller and a personal computer;

- optical isolation for the COM port - galvanically decouples the microprocessor unit and the serial port of the computer, as well as pairing the standard signal levels of the serial port of the computer (-12V for logical units and + 12V for logical zero) and the serial port of the microcontroller (5V for logical units and 0 In for logical zero) to ensure stable operation of the device and prevent its failure.

All electronic components of the remote control are powered by a separate power supply unit that converts AC voltage of 220 V into a stabilized voltage of 5 volts. To eliminate possible overloads during short-term voltage surges in the supply network, a varistor with a voltage limit of 250 V is installed at the input

Buttons, switches and LEDs are connected to the control unit using two flat cables with connectors: one is used to connect buttons and switches, the second - to connect LEDs. The transition from each of these loops to loops of printed circuit boards is carried out using special splitter blocks.

Interaction of consoles with the Application Server is carried out using a distributed microprocessor control system - controllers located on the chassis inside the consoles. The number of controllers for each remote control is determined by the number of switching and display elements used in the remote control and can be from one to four.

The interaction between the controllers is based on a serial CAN-interface.

7

Each controller unit has its own identification number (from 0 to 15), set by the corresponding switches (jumpers) on its board and can be connected via a USB or RS-232 interface to a personal computer. One unit is the master (it is connected to one of the computers on the workstation via a USB port), the rest are slaves.

The software structure of the training complex for the operational staff of the sorting slide consists of the following modules:

- dynamics server;

- application server;

- expert system for the formation of the learning path;

- system of computer image generation (SKGI);

- server signaling.
