Description

The invention relates to the field of information and communication technologies, namely, equipment that provides training for boatmasters in accordance with the model course of the International Maritime Organization IMO 1.07 (RADAR Navigation, Radar Plotting and use of ARPA Model Course).

In accordance with the standards of the International Convention on the Training and Certification of Seafarers and Watchkeeping (STCW), this International Maritime Organization (IMO) has developed model training courses for marine specialists that define the goals and objectives of this course, as well as the competence of students using the necessary equipment.

For example, the well-known analogue, model course 1.07 (RADAR NAVIGATION, RADAR PLOTTING AND USE OF ARPA Radar Navigation at Operational level (Model course 1.07) (1999 Edition), ISBN 978-92-801-61106) is intended for study using a special equipment of the discipline "Collision avoidance of ships". It is well known that ship collisions often occur due to the boatmaster’s errors in the improper use of radar and radar equipment both in limited visibility and in good weather. With the development of a situation of dangerous rapprochement, a common mistake is to change course on the basis of insufficient information in their use or exceeding the unjustifiably set safe speed. Radar information and radar tracking equipment can help the officer on duty to ensure proper surveillance in areas with heavy traffic.

The aforementioned model course 1.07 requires a radar simulator with an instructor remote control and a sufficient number of displays for your ship to work with a group of students. Special equipment should include at least two operational shipborne radar stations (PDNM Convention AI / 12, Part 1, paragraph 4.3), which should simulate the operational capabilities of navigational radar equipment with all applicable IMO standards (resolutions A.222 (VII), A. 278 (VIII), A.477 (XII) and A.832 (19)). Each workstation of the simulator must be provided with a maneuverable tablet and cushioning tool. To present the theoretical part of the course, an audience with a blackboard and multimedia complex is needed.

In compliance with these standards, in particular, in all marine educational institutions, ship control simulators and auxiliary computer classes are installed to prepare students for ship control on the basis of radar information, which have common disadvantages, such as: the high cost of the supplied special equipment, the limited number of jobs, the need for multiple personal computers for each workplace, software overload complement nymi functions not related to the goals and objectives of a particular course.

The closest prototype and a promising technical tool for simulator training is a simulator complex for ship control for the training of skippers in a local computer network in accordance with the IMO model course of TRANS AS NAVI-TRAINER 5000 (http://www.ru.transas.com/products/ simulation / navigational-simulators / NTPROSTCW), containing instructor control panel (PUI), trainee control panels (PUE), made in the form of standard individual personal computers integrated into a local computer network containing a high-speed channel information transfer provided by plug-in devices for short-term exclusive use within a computer complex. At the same time, it contains a set of displays on each panel for processing information about the mutual movement of vessels, a console simulating the students' control of the vessel, an audience with a blackboard and a multimedia complex, a simulator power supply, a specially acquired, installed and configured local computer network for exchanging information with the instructor’s console and computers for each monitor of the student’s console to simulate the equipment of the navigation bridge and the mathematical model of the vessel, namely, three computers for each worker her place, i.e. contains specialized marine training equipment.

The simulator software used is installed on the network server, which includes workstation consoles. When using the simulator, tasks are distributed among the workstations by the instructor in the “Setup Tasks” mode, which is created using the configuration editor and stored on the instructor’s server. The simulator tasks are performed by the router program in accordance with the specified task configuration. In accordance with their functional purpose, learning tasks are combined in two types:

- route - general purpose tasks;

- navigation bridge - tasks that imitate the object. The route group, as a rule, includes the technical elements:

- remote instructor workstations (instructor);

- station of the movement of the vessel or physical modeling of the station process (model);

- stations of interaction with external systems of simulators (ports). Typically, a navigation bridge group contains:

- stations for visual presentation of the virtual space of the simulator;

- consoles simulating equipment or equipment of a simulator of control of a simulated vessel.

A known simulator can have only one type of route group and up to 32 groups of the navigation bridge in the domain of the simulator.

Known navigation simulators of this type in any configurations allow you to carry out training in working with modern radar / ARPA (automatic radar plotting tools). In this case, computer simulators are used, the working blocks of which are located in the instructor's room. The training complies with international standards, in particular PDMNV-95 (International Convention on the Training and Certification of Seafarers and Watch), and includes training for the following training programs:

- radar (radar station) surveillance;

- maintaining radar pads;

- collision avoidance based on IMO rules and using a radar tablet;

- orientation in the situation, including the determination of the elements of movement of goals, distances to goals, bearing, courses and speeds;

- performing calculations on goals, such as CPA (shortest distance), TCPA (shortest distance), changing courses and speeds;

- Configuring radar / ARPA displays and maintaining them in working condition.

The known system operates as follows:

- the instructor’s control panel (ISP) establishes a pre-prepared exercise, for example, safe passage of the vessel in the area of heavy navigation under conditions of limited visibility;

- on a local computer network, this task applies to each student’s control panel (PUW), taking into account the specific task for each student;

- at the instruction of the instructor, each student at his workplace controls his ship using the steering wheel and the machine telegraph console simulating the control of the ship to set the course of the main engines, assessing the situation using simulation of a radar station and automatic radar plotting (ARPA), moreover this imitation is carried out using both external devices located at the instructor's workplace, and on the computers of the student’s control panel (PUU);

- after the end of swimming, students can familiarize themselves with the result of the recorded log file on the instructor's analyzer and get a printout of these results;

- since the simulator is equipped with a video and audio surveillance system, these records are used in the analysis of completed exercises.

The disadvantages of the known technical means adopted for the prototype are as follows, namely: all navigational simulators supplied to marine educational institutions:

1) are an expensive special acquisition, since the software is bought and delivered together with a specialized set of equipment for the instructor’s console and students’s workplaces, which leads to the inevitable limitation of the number of boatmasters engaged in the simulator process;

2) require the allocation of separate rooms, which cannot be used for any other purposes, due to the fact that a specially delivered, installed and configured local computer network is used, tied to the necessary specialized software for the simulator;

3) each workplace to simulate information about the location of the vessels and control the vessel requires the presence of at least three personal computers included in the delivery package of the simulator equipment adopted for the prototype;

4) the necessary software used to ensure the operation of the well-known simulator is overloaded with unnecessary functions that are not IMO requirements for this particular course, which again leads to a rise in the cost of the product.

For these reasons, instructors and teachers, due to the lack of jobs for students, are forced to increase lecture hours due to practical exercises on simulators, which does not contribute to the achievement of the required training standards. It is significant that lecture training can be effective only if accompanied by practical exercises.

The technical problem to which the claimed invention is directed is to eliminate the above disadvantages, namely: the high cost of the supplied specialized equipment, the limited number of jobs, the need for several personal computers for each workstation, software overload with additional functions that are not related to goals and objectives this particular course.

Characteristically, in the well-known training complex for the preparation of boatmasters, which contains an instructor control panel (ISP), trainee control panels (PUO) with a set of displays for processing information about the mutual movement of vessels and a console simulating the control of a vessel, an audience with a blackboard and a multimedia complex, the simulator’s power supply unit, a well-known specially delivered, installed and configured local computer network is used to exchange information of the instructor’s console (PUI) and trainee’s panels (PUU).

To solve this problem and developed the claimed simulator.

The stated technical problem is achieved by the fact that in the well-known training complex for the preparation of skippers in the local computer network in accordance with the IMO model course, containing the instructor’s control panel and the student’s control panels, made in the form of standard individual personal computers integrated into a local computer network containing high-speed information transfer channel provided by plug-in devices for short-term exclusive use within the territory orii of a computer complex, UNLIKE IT, the local computer network of the claimed training complex is designed as a public network, which is serial and connected to a standard generally accepted channel for transmitting information for use within the entire organization of a training complex user, while it additionally contains a radar simulating unit , and a block simulating an automatic steering device and engine telegraph engine control, which is connected to a standard personal computer via without a standard USB port, and each computer of the student’s workplace has the necessary software installed with the specific task of training and monitoring knowledge in established competencies, and individual personal computers in the integrated local public computer network have communication with each other through the instructor’s control panel within the assigned group instructor to perform a joint discrepancy task.

The combination of distinctive and restrictive features of the claimed invention, expressed in the use of a standard local public computer network, which is a serial computer and does not require special development and configuration, as well as, in combination, and in the installation of an additional control simulation unit, together with their connections, provides the achievement of the technical task in the following way:

- on the computer that was assigned by the instructor’s control panel (ISP) during the installation of the system, pre-prepared exercises are installed, and from the same ISU computer, students are distributed into groups at the instructor’s discretion;

- on a local network, these tasks are distributed to each group of students, respectively, and to each student’s control panel (PU), taking into account the specific task for each student;

- at the instruction of the ISP instructor, each student at his workplace controls his ship using a block simulating the operation of the rudder and a machine telegraph to set the course of the main engines, assessing the situation in his group of ships using simulation of a radar station and automatic radar tracking (ARPA), and this imitation is carried out using software (not an object of claim) installed on the student’s workplace computer;

- after the end of training swimming, students can familiarize themselves with the result of the recorded log file at their workplace of the student’s control panel (PUE), as well as all information about the commands given to the students during the swimming process, is recorded in the database for the group of students located on the computer, which, when installing the system, was assigned by the instructor’s control panel (ISP), and these records are used to parse the exercises performed and evaluate the actions of the trainees;

- in addition to the tools for analyzing and evaluating the student’s actions to solve a given exercise, the optimal training option for maneuver for comparison with the student’s actions is provided in the inventive training complex on the learner’s control panel (PUI) and on the instructor’s control panel (PUI), which is achieved thanks to a specially developed software

- in addition to the functions of a well-known training complex, individual work of a student is possible at each workplace (PUW) even with the instructor's remote control (PUI) turned off; when the instructor’s console is off, the student is given the opportunity to “transfer” from ship to ship in order to be able to assess the situation from the position of each participant in the exercise, which is also achieved thanks to specially developed software;

- all this workplace software can be installed on the trainee’s personal computer and outside the simulator’s room, and the trainee can independently continue to consolidate the acquired knowledge and skills within the entire organization of the user of the training complex for the training of boatmasters in accordance with the established model course of the International Maritime Organization IMO 1.07 ;

- unlike the well-known training complex, the claimed complex can be simultaneously launched to perform several independent exercises for various groups of trainees, formed at the discretion of the instructor, and the number of jobs is unlimited (the only limitation is the computer’s random access memory, which is assigned by the instructor’s control panel (PUI ) when installing the system), which is achieved when the ISP is enabled due to the possibility of communication between individual personal computers within the assigned Second group of trainers in the local public network;

- the disadvantages of the known technical solutions:

1) unlike the prototype, it does not require the purchase of a specialized, expensive set of equipment with a specially supplied and configured local computer network, since the previously used computer equipment used for general educational purposes is used;

2) allocation of special separate rooms is not required, since general-purpose classes using computer equipment are used;

3) one personal computer is installed at each workplace to simulate information about the location of vessels and control the vessel using specially developed software;

4) the software (not an object of claim) is not overloaded with unnecessary functions that are not necessary IMO requirements for this particular course, due to a special selection of the simulator's functions performed in accordance with the goals and objectives of this particular course.

The screen of a modern ship's radar is almost identical to the screen of a personal computer. And personal computers are much more accessible for students than the well-known specialized training equipment. Therefore, the competencies of the IMO model course according to the claimed invention are achieved using personal computers with appropriate software in a standard serial public local network.

The invention is illustrated by the following graphic material.

In FIG. 1 presents a block diagram of the elements of the inventive simulator in a standard local public computer network.

In FIG. 2 shows an example of solving the problem of divergence of vessels in the process of training navigation.

In FIG. Figure 3 shows a photograph of the workplace at the moment of course change using the control element at the experimental operating training complex in the applicant - Maritime State University named after adm. G.I. Nevelsky.

The inventive training complex for the preparation of boatmasters, in accordance with the international model course IMO 1.07, contains (Fig. 1) an instructor control panel (PUI) 1 and individual on-site control panels of each of the trainees (PUO) 2, which are standard connected to each other through ISP 1, individual personal computers 2.1, 2.2, 2.3, etc., combined with the ISP standard local computer network in the form of a public network, which is serial. Moreover, all student’s control panels (PUFs) 2 are combined into groups 3 to jointly solve the specific problem of discrepancies at the discretion of the instructor (as an example, four groups of three workplaces are shown; in fact, the instructor has the ability to create groups of from one PUF 2 separately before all ASN 2 in one group if there is an appropriately prepared assignment). At each workplace of the student, additional blocks 2.1.1, 2.2.1, 2.3.1, etc., connected in the form of standard control elements of serial joysticks simulating an automatic steering device (not connected) are connected to his computer via a standard USB port (not shown) shown), radar (not shown) and engine telegraph (not shown). In this case, the screen of the personal computer is identical to the screen of the ship’s radar (not shown), and the computer network itself contains the applicable high-speed data transmission channel provided by the connected devices 1; 2.1; 2.2; 2.3 etc. until 2.12 for short-term monopoly use within the entire organization of the user of the training complex (Maritime State University). Moreover, on each computer 2.1; 2.2; 2.3 etc. workplace installed software with the specific task of teaching skills to work with the radar and control knowledge in the established competencies, and all computers 2.1; 2.2; 2.3 etc. workplaces are grouped in groups 3 to jointly solve the discrepancy problem at the discretion of the instructor.

The inventive training complex is used, including, and in the same standard generally accepted manner as in the known prototype:

- on the computer, which was assigned by the instructor’s control panel (ISP) 1 when installing the system, pre-set exercises for each group 3 are installed for a joint solution (for example, the situation of dangerous proximity of three vessels shown in Fig. 2, or any other task developed including, with the help of a special program (not an object of claim) “Program for generating a model of unfavorable rapprochement of vessels with the subsequent choice of maneuver for safe divergence”, certificate of state registration No. 2013661165 of 11.29.2013;

- the simulator on the student’s control panel (PUI) 2 is started by command from the instructor’s control panel (PUI) 1 using a network software package (not an object of claim) “A software package for a local computer network that allows running executable programs on any network computers by command from the host computer ”, state registration certificate No. 201661034 dated 09/28/2016;

- on a local public network, these tasks are distributed to each student’s control panel (PU) 2 as part of the corresponding group 3, taking into account the individual specific tasks for each student on his personal computer 2.1, 2.2, 2.3, etc. until 2.12, using software based on computer programs (not the object of the claim) “Training complex in the local computer network for pre-training navigators in accordance with the IMO 1.07 model course (RADAR Navigation, Radar Plotting and use of ARPA Model Course)”, certificate on state registration No. 201661077 of 09/28/2016;

- at the instruction of the instructor, each student at his workplace performs the task of managing his ship as part of his group of ships 3 by simulating the aforementioned rudder and machine telegraph blocks 2.1.1, 2.2.1, 2.3.1, etc. until 2.12.1 to control the ship and set the course of the main engines (not shown), assessing the situation as part of its group of ships 3 using a quantitative assessment of the distance of shortest approach (CPA) and the time of shortest approach (TCPA), taking into account the established conditions and limitations of the International Collision Avoidance Rules (MPPS), using simulation of a radar station and automatic radar plotting (ARPA) tools, and this particular simulation of radar, ARPA and ship control is carried out with the help of software developed by the applicant, installed respectively on the computer of the workplace of each student (PU) 2.1, 2.2, 2.3, etc., and on additional blocks 2.1.1, 2.2.1, 2.3.1, based on a computer program (not the object of the claim) “Modeling the situation of approaching ships on the radar screen with the subsequent choice of maneuver for safe discrepancy”, certificate of state registration No. 20155617161 of 05/08/2015;

- after the end of training swimming, trainees can familiarize themselves with its result by the recorded log file at their workplace (ПУО) 2, as well as all information about the commands given to the trainees during the swimming process, is recorded in the database for the group of trainees located on the computer, which during the installation of the system, it is assigned to the instructor’s control panel (ISP) 1, and these records are used to analyze the exercises performed and evaluate the actions of students the specified database is a regular file system, sorted by groups and time classes.

So, for example, the instructor (ISP) 1 distributes for one of the groups of trainees 3 to their personal computers 2.1, 2.2, 2.3. this task is of the following content:

In FIG. 2, in the navigation chart (scale in nautical miles), after a three-minute time interval, an example is given of a joint solution to the discrepancy problem for a group of three vessels interconnected in this group 3 through the ISP console 1, in which each student being interconnected with the others in this group 3 , “Manages” his, respectively, vessel A, B and C. At the instructor’s command, each student at his workplace solves this problem of managing his vessel as part of his group of vessels by simulating the aforementioned rudder and machine telegraph blocks 2.1.1, 2.2.1, 2.3.1, etc. to control the ship and set the course of the main engines (not shown), evaluating the situation in its group 3 by quantifying the shortest approach distance (CPA) and the shortest approach time (TCPA), taking into account the established conditions and limitations of the International Rules for the Prevention of Collision (MPPSS) ) using a specific simulation of a radar station (radar) and automatic radar plotting (ARPA). Through blocks 2.1, 2.2, 2.3, trainees determine the elements of the movement of targets in their group 3 and evaluate the situation using a radar tablet (not shown) and playing a test maneuver (not shown), make and execute decisions on maneuvering according to the standard methodology. In particular, at time 00:00, vessel A follows a course of 250 ° at a speed of 20.0 knots, vessel B follows a course of 317 ° at a speed of 12.0 knots, vessel C follows a course of 155 ° at a speed of 18.0 knots. If they all keep their heading and speed unchanged, then after 24 minutes a dangerous approach of vessels A and C is inevitable, after 33 minutes a dangerous approach of vessels A and B is taught. Students with a specific simulation of the use of radar and automatic radar plotting (ARPA), carried out with using software on your computer, through blocks 2.1, 2.2, 2.3, determining the elements of the movement of targets and assessing the situation using a radar tablet (not shown) and playing a test maneuver (not shown), according to the standard method Odick make decisions: vessel A turns 12.8 ° to the right after 12:00 and returns to the previous course after 22 minutes, vessel B turns right to 037 ° after 12:00 and returns to the previous course after 33 minutes, vessel C after 12:00 min turns right to the course 206 ° and returns to the previous course after 36 minutes. In this case, the moment of course change using the control element - block 2.1.1, simulating a machine telegraph and steering on the simulator, is illustrated in FIG. 3 - photos of the workplace. The maneuvers were performed at the set time, taking into account the maneuvering characteristics, so the ships did not approach each other at a distance of less than two miles, which was required by the terms of the task in accordance with the requirements of the MPPSS, and thus each of the students solved the task. So use the claimed training complex. Moreover, the same task or any other appropriately prepared task can be distributed to other groups of trainees 3, and they can be performed simultaneously independently of other groups 3. Moreover, the instructor, when preparing the task, can reserve an additional arbitrary number of vessels that he can set in advance an arbitrary trajectory with the performance of specified maneuvers at given points in time and which he can exponentially control from his console instructor PUI 1 at any time ebnogo sailing in ships given his chosen group 3.

The main information and communication task of the claimed invention is the development of a training complex for the preparation of skippers in accordance with the IMO model course, which, provided that all the requirements for training standards are unconditionally, contributes to a more accessible training process for skippers and to raising teaching standards.

The main advantage of the claimed invention is that expensive special equipment and software is replaced with standard serial equipment and the necessary software, more adapted to educational goals.

Prototypes have been tested at the Maritime State University. adm. G.I. Nevelsky, and there is a developed software that can be provided to the relevant party by the Applicant in a short time. In this regard, there is no need for special computer equipment and a special local network: the usual standard public local network and standard serial personal computers in the aggregate are quite enough.
