Description

The present invention relates to educational and technical means and can be used to form the skills necessary in the real working conditions of the SAC operators.

The role of the human factor in ensuring the successful functioning of complex, man-made technical systems is truly enormous. This is especially true for specialists whose professional activity is associated with the detection and classification of objects based on the information displayed on the monitors of their workplaces. The quality of work of modern complex systems, the efficiency of their application and, as a rule, the safety of people and technology depend to a large extent on the professional knowledge and experience of these people, their skills and the level of practical skills for processing stochastic information.

For the training of operators involved in the processing of information in complex dynamic systems, educational and training tools are used to reproduce the working conditions that may arise in their professional activities.

A known simulator for the preparation of sonar (see US patent No. 4932880 from 12.06.90, application No. 335650 from 04/07/89). This simulator is designed to train operators of portable sonar locators. The simulator is a dialogue-based programmable tonal sonar, in which recordings of hydroacoustic signals in natural conditions are synchronized with codes on a separate track of the magnetic medium, ensuring the inclusion of the corresponding graphic displays of natural sound signals. The simulator also provides the ability to select typical sonar signals with their repeated repetition and digitally rewriting onto a flexible magnetic disk, which provides an interactive operator training mode.

The closest analogue of the claimed invention is an automated training complex for the training of crews of ships, designed to form the skills necessary in the real conditions of activity of ship operators. The complex contains a set of training-operating samples of students' workstations installed on a swinging platform, including a sonar workstation, a training management post, a computer-modular complex and a data exchange system. All elements of the complex are interconnected via a local network (see AS No. 2234138, class G09B 9/06, 2004.08.21). At the same time, the sonar workstation simulates the means of control panels and the operation of a specific sonar station installed on this ship.

The disadvantage of analogues is that they do not fully provide training for operators of various sonar systems, the main activity of which is the detection and classification of signals according to the information displayed on the indicators of their workplaces, taking into account the classification features and movement parameters of objects, as well as the hydrological characteristics of the area training, as they do not allow to reliably create conditions for training at students' workplaces due to the lack of adequate software models for sonar stations that simulate the conditions for receiving a sonar signal in the given training conditions, determined by the hydrological and weather conditions of a given region of the oceans.

The technical result of the invention is the creation of an intelligent simulator that provides training for sonar operators on the use of various types of sonar systems based on models of their measuring instruments, HAC control panels and models that simulate the processing of sonar signals from surface and underwater objects. At the same time, models that provide simulation of operator panels and acoustic signal processing paths in both active and passive modes of operation of the HAC station, in turn, are as close as possible to the actual training conditions, determined by the geographic coordinates of the ship, its motion parameters and the corresponding hydrological and meteorological conditions, and allow you to provide a training course for sonar operators in their professional activities.

An intelligent simulator is a combination of a training management post and workplaces of trainees, interconnected by software and hardware of a local computer network. The training management post (PRO) includes an instructor's workplace consisting of a general-purpose personal computer and a database server. The unified workplaces of trainees (URMO) are also built on the basis of a general-purpose personal computer. The information displayed on their monitors is accompanied by the generation of audio data sold by means of a multimedia computer, and provides in the workplace of the students an imitation of the sound signals of the operating HAC devices, sea noise, the working mechanisms of the ships, including the mechanisms of the ship on which the sonar station is located, and also imitation of the noise of marine animals.

The specified technical result is achieved by the fact that the training complex proposed as an invention includes a missile defense system, which includes the instructor’s workstation (RMI) and a database server containing electronic data of the classification features of tactical environment objects and their spatial position and movement parameters, an electronic cartographic database data of various regions of the oceans, as well as data on the results of training, phonograms of acoustic noise of objects and marine animals. The unified workstations of students are interconnected via software and hardware of the local computer network with RMI, including a LAN switch that provides communication between the workstations of students and the training management post.

Figure 1 presents the structural diagram of the simulator for training operators of various types of sonar systems. It consists of: a training management post (1), a set of unified workplaces for trainees (2), and a local area network.

Figure 2 presents the structural diagram of the URMO. It contains: a computing device (3), a local area network adapter (4), two display modules (5, 6), a display keyboard (7) and an acoustic system (8). At the same time, the computing device provides on the display modules the display of the appearance of measuring instruments, HAC control panels and the image of the location marks of the tactical environment objects.

Figure 3 presents the structural diagram of missile defense. It contains: the instructor’s workstation (9), which contains a software switch, training management tools, data preparation for classes, as well as software for recording the actions of students and a database server (10).

Figure 4 presents the structural diagram of the RMI. It contains: a computing device (11), a software switch (12), a network adapter (13), a display module (14), and a display keyboard (15).

Figure 5 presents the structural diagram of the database server simulator. It contains: a computing device (16), a network adapter (17), an electronic database of models of hydroacoustic stations (18), an electronic database containing a cartographic description of the oceans with characteristics describing the topography of the bottom (19), a database of training results for students ( 20), a database of trainees containing registration data on trainees (21), as well as a database of hydroacoustic properties of the ship (22), including the corresponding characteristics of the ship's hull, characteristics of a torpedo and rocket pednogo weapons, as well as a soundtrack of their propulsion systems and marine animal sounds.

The technical result of this invention is that the proposed device as a simulator provides training for operators of sonar systems for their combat use due to the presence of electronic models of various types of HACs and the possibility of assigning various options for tactical conditions, hydrological and meteorological conditions with RMI in the training leader areas of the oceans. This device as a simulator allows you to provide a significant increase in the level of professional training of operators of various sonar systems.

The work of the proposed device can be divided into four stages. The execution of these stages is controlled by the head of training from the workplace of the instructor by training (9), which is part of the missile defense system.

At the first stage, from the workplace of the instructor (9), the operability of the simulator hardware is checked using standard operating system procedures, the trainees are registered using the trainees database (21), the type of HAC model is selected and it is downloaded from the server (10) from the database ( 18) to workplaces of trainees.

At the second stage, from the instructor’s workplace (9), on the basis of the databases (19 and 22), initial data are prepared for the training, which include: choosing the training area, setting the motion paths of tactical objects, their types and hydrological and meteorological conditions training (excitement of the sea, the presence of precipitation, etc.), including the presence of marine animals, their type and trajectories.

At the third stage, operations are performed that ensure the process of conducting the lesson. At the same time, at each workplace of the student, his actions are recorded, data about which is recorded in real time in the corresponding registration files of the training results database (20).

At the fourth stage, based on the data from these registration files, a analysis of the lessons is carried out.

To manage the stages of classes, the training manager must complete the following actions before classes.

At the first stage, the training manager should ensure that the simulator’s technical equipment is turned on at his command.

At the same stage, from the instructor’s workplace (9), he starts a program that provides testing of technical means of the simulator’s workstations. If they are operational, the students are registered using the database (21), after which, from the instructor’s workplace (9), the training manager selects the HAC model from the server (10) and, using the switch (12), provides through a local computer network its loading on a PC of standardized workplaces of students (2).

At the second stage, the training manager makes a choice from the database (19) of the server (10) of electronic data characterizing the oceans, and sets the tactical situation using the display module (14) and the display keyboard (15) of the instructor’s workstation (9). Tactical situation data includes the coordinates of the location of tactical situation objects, the type of ship, the parameters of the trajectory of their movement in real time, as well as data describing the hydrological characteristics of the training area.

At the third stage, the training manager starts the training session from the instructor's workplace (9). During the training process, the head of training from the instructor's workplace can introduce new objects of a tactical situation, change the motion parameters of existing objects of a tactical situation, and also change the parameters of hydrometeorological conditions.

At the fourth stage, the head of training, based on the data of registration files located on the magnetic media of computing devices (11) workplaces of students, provides analysis of the lesson, on the basis of which it enters data on the results of the lesson for each student in the database of students (21).

Trainees, being at their workplaces, at the instruction of the training supervisor, turn on the technical means and await the results of checking their performance. If the technical means of the URMO are workable, on the instruction of the supervisor of training, they register as a student.

After registration, students are waiting for the loading of a model of a sonar station to their workplaces and, upon the instruction of the training supervisor, begin to perform their functional duties in detecting and classifying tactical environment objects. Moreover, in their actions, they should, based on the information displayed on the monitors of their display modules (5, 6) and sound information, detect, classify and calculate the motion parameters of tactical environment objects.

As a result of the implementation of the proposed simulator, the training of operators of hydroacoustic systems of surface ships is brought as close as possible to the real conditions of their work on the ship, which will allow them to practice practical training tasks.
