Detailed ways

The training simulator is a multiport computer network that can serve both an instructor and a group of trainees and can operate in a multitasking mode. A computer network according to the Ethernet standard involves the network card connection of several computers (structured network) via cables or switches and network cards generating synchronization from signals.

A simulator for crew training on board a ship consists of a set of TWS1 and an IWS2 corresponding to the number of trainees. Each TWS1 includes a personal computer system unit (PCSU) 3, a control panel (CP) 4 with a data input device (DID) 5 and peripheral devices, first and second monitor displays 6, 7, wherein there is a DID5 The CP4 is connected to the PCSU3 through a serial port 8, while the first and second monitor displays 6, 7 are connected to it through respective user interfaces, namely an analog interface RGB9 and a digital interface DVI10. A power switch unit (PSSU) 11 is connected to CP4 having DID5, to first and second monitor displays 6, 7, and to PCSU3 through a network port. Each TWS1 is connected to an uninterruptible power supply (UPS) 13 connected to an external power source (not shown) through PSSU11.

IWS2 comprises PCSU14; "mouse" manipulator 16 of keyboard 15 part peripheral equipment; Printer 17 and monitoring monitor 18, they are respectively connected with PCSU14 by serial port 19, parallel port 20 and video adapter 21; And also comprise a concentrator (LC) 22, which is connected to the PCSU14 of the IWS2 and to the PCSU3 of each TWS1 via a command-driven interface 23. The system units PCSU3, 14 are embodied according to the Ethernet standard. The PCSU14, printer 17, monitor display 18, and LC22, which constitute the IWS2, are connected to a UPS24 connected to an external power supply. All connections to the uninterruptible power supply are connected in parallel so that each connected unit gets an equal voltage supply at the input.

The LC22 is designed for data compression in a way that saves space on the PCSU 14 hard drive and increases data transfer rates through command-driven interfaces 23, especially SCSI, which uses direct memory access for data transfers. The need for data compression stems from the nature of the training material (multimedia situational tasks) that is processed through a user interface, namely the analog interface RGB9 (to provide image color reproduction) and the digital interface DVI10 (to receive color text and graphic representations) with Duplication is performed on monitor displays 6 and 7 in TWS1 connected to the system unit video adapter of PCSU3. In order to make the training conditions as close as possible to the actual system operating conditions, the monitoring displays 6, 7 in the TWS1 are configured in exactly the same way (ie superimposed) as the screens at the system operator's station.

In TWS1, PCSU3 is provided with a switch board 25 through which the start signal from PSSU11 enters PCSU3. The switch plate 25 is mounted in a free position, it is designed for attaching the strap of an extra module to the casing of the PCSU3. One side of this board is linked with the connector PWR SW of the main board (MB) 26, so that the PCSU3 is booted from the PSSU11 while the TWS1 is locked for unauthorized access or the MB26 is cut off from the power supply via the UPS13 (especially the basic microprocessor, RW memory, etc.).

In each computerized TWS 1, the control panel (CP) 4 is implemented in the form of a control panel simulator for the operator of the onboard systems of the mobile object. The data input device (DID) 5 of the CP4 is connected to the PCSU 3 through a serial port 8 typically designed to link a keyboard and "mouse" controller. In DID5 there are the following TWS1 controls:

- The power on/off key, relying on it to switch the TWS1 on/off through the power supply (not shown in the figure);

- A keypad with which to define the modes and data inputs required for the operation of the TWS1 (not shown in the figure). In this keyboard, a matrix switching of keys with a tactile response effect is implemented. Information is sent from the keyboard to the PCSU3 via serial port 8 (keyboard PS/2). In DID5 of CP4, a "touch pad" sensor manipulator (electrical duplicator) can be utilized in order to increase the data input rate;

- Motor locks ("Lock Power", "Lock Mode", "Lock Cancel Initiate") to prevent unauthorized access to the controls in DID5 (these locks are not shown in the diagram);

- Status indicator for CP4 (not shown in the picture).

The power supply for DID5 is performed from PSSU11, which has DC voltages carried (5V and 27V) and depends on the signal from DID5 of the other device TWS1 (~50Hz, 220V). This way ensures the necessary parameters of its power supply. Similar to a shipboard system controlling a moving target, it initiates the on/off switch of TWS1, and also generates a start signal for PCSU3.

After receiving the cut-off signal from DID5, PSSU11 will stop generating supply voltage (~50Hz, 220V) to device TWS1. However, DC voltages (5V and 27V) continue to be generated as long as mains voltage (~50Hz, 220V) is applied to the PSSU 11 via an uninterruptible power supply (UPS) 13 .

In the PSSU11, short-circuit protection is guaranteed by means of fuses.

Configure indicators "PWR" and "ON" in the casing of PSSU11. The "PWR" indicator illuminates to show that supply voltage (~50Hz, 220V) is applied to unit PSSU11 and that the unit generates supply voltage (5V and 27V). The "ON" indicator is illuminated to show that the power switching device 11 is generating supply voltage (~50Hz, 220V) to the device TWS1.

TWS1 and IWS2 are computerized workstations based on IBM compatible PCs with processing power, at least equivalent to PentiumIII. To organize the information interoperability of workstations of a similar nature according to the Fast Ethernet 100Base-TX IEEE802.3u standard, thus ensuring a maximum possible data transfer rate of up to 100Mb/s at the expense of data compression when using a concentrator installed in the IWS .

The software environment that keeps the simulator running includes a built-in Windows XP operating system. A software environment is configured on an external data carrier (data recorder/reader on optical disc) and includes a shipboard system for controlling moving targets and interface ships with carrying programs for target motion trajectory calculations A multimedia emulator for the loaded system, and a database for training scenario tasks using the operating system Windows XP Professional and the capabilities of an MSDN library. The software environment enables the operator to perform operations according to the necessary training and information patterns, to set up the simulator in different training modes under the supervision of an instructor by simulating real-life situations (including online mode), and also to protect the system from damage Unauthorized access.

A simulation device according to the invention operates as follows. After switching on the simulation device, the instructor in the IWS 2 uses the keyboard 15 with the "mouse" manipulator 16 to select a specific task from the database of situational tasks stored in the PCSU 14 for the control object. The video signal enters the monitor screen 18 of IWS2 through the video adapter, and at the same time, the encoding task video signal and interface 23 enters the PCSU3 input of each TWS1 through the LC22. The received signal enters the RW memory of PCSU3, namely the system board (SB) 26, and enters the monitors 6, 7 of TWS1 through the user interface. The task orientation trainee enters the necessary data (solution) into the PCSU3 via the DID5 of the CP4 and transmits the signal (solution) to the IWS2 via the interface 23 . All TWS1 operate independently of each other, with the possibility of synchronizing solutions from all TWS1 into IWS2 to perform different tasks, thus providing an assessment of decision speed, decision execution, etc. during dynamic training. Varying the task by introducing various parameters for the calculation of the target motion trajectory using standard calculation procedures, the instructor wants the trainee to solve the controlled task in similar and non-similar situations, improving control while providing communication between TWS1 and IWS2 Skill. The use of multimedia simulators of actual operator panels for controlling target motion enables operators to enhance their skills in controlling real-world systems in a variety of situations.

Training exercises using the PSSU11 under interruption conditions simulate the dissimilar situation of disconnection in motion control systems and failures to be involved by the status indicators of the CP4 in interface systems. When simulated in this way, tasks successfully performed by trainees (under stress) increase their reliability in practice at the expense of the learned ability to predict the outcome of their movements.

A complete set of tasks for training in TWS1 using the software environment allows:

- simulation of the operational process of the onboard systems used to control moving targets with regard to their working settings, their preparation and intended use, and the display of data identical to those produced by the real control system in all its modes of operation;

- Receive target data, voyage data, and data for a complete set of moving targets for their intended use, obtained from IWS2 upon pending training missions;

- Receive and execute control commands obtained from CP4 via DID5;

- solve practical functional tasks of shipboard systems for controlling moving targets;

- archiving of the results of operations, forming messages identical to those produced by the real control system and its communication with IWS2;

- Monitor the software integrity of TWS1.

IWS2 ensures the following functions are performed:

- Execute the simulation device, trigger and turn off the monitoring;

- control the mode of operation of the simulation device;

- control the trainee's training mode;

- Create, update and expand the training task database;

- Trigger and close program execution in TWS1;

- prepare and enter the initial training conditions, their operational modifications and monitor the values to be entered;

-Simulate and communicate target data, voyage data, and a complete set of moving target data for their designated use. These data are individual to each TWS1 and identical to those from the interfaced ship system, according to the protocol for interfacing with the shipboard system used to control the moving object;

- Simulate dynamic changes associated with real-time target movement;

- control of training sessions during operation;

- for lesson planning, aggregation, monitoring and analysis;

- registration of trainees;

- monitor training levels and results;

- Restoration of application software in TWS1 and IWS2 in case of failure.

Use the portable storage battery to connect the power supply of TWS1 and IWS2 through UPS13 and 24 respectively. This method can simulate the normal operation of the device unit for at least 5 minutes when there is an unauthorized disconnection or when the power supply parameters exceed the acceptable limit, etc., which can stop the software in a short time and prevent software damage and information loss.

The simulation unit has a progressive software and hardware system for data protection against unauthorized access, for which several limits are set in each workstation:

- Restrict access to the operating system with a password that is individual to each workstation;

- Restrict access to the program using passwords individual to each IWS2 (as for TWS1 these are individual to each trainee);

- Access to on/off switching and operation in TWS1 is restricted by means of keys individual to each workstation using the motor locks of the controls in the data entry device 5 .

The simulator has a progressive software recovery system for failures.

In the event of an application failure in TWS1, the system software (operating system) is restored from IWS2 if it remains in service.

In order to restore the software in the event of a system software failure, CDs from a set of data carriers are relied upon to restore the program. On each CD is recorded an image of the software installed on the PC of one workstation with corresponding settings depending on the workstation type (IWS or TWS) and the workstation number (TWS1 to n). During software restoration, an automatic identification of the PC devices is performed, so that CDs from a set of data carriers can be used only on those PCs forming the emulator.

In this way, the technical effect to be achieved using simulated means according to the invention remains in the protection of the system from unauthorized access and in the hardware implementation of the process simulating a non-analogous situation of the real system. This provides efficient training on a variety of tasks with varying degrees of complexity.
