Description

The claimed technical solution relates to simulators, in particular to simulators with a simulated view from a vehicle, and can be used for complex group and / or individual education and training of personnel for the operation and maintenance of complex control systems, in particular control systems for various types of water transport.

Comprehensive simulators are known for group and / or individual training and training of maintenance and operating personnel of various control systems (see, for example, “Interactive training system” according to RF patent No. 2271040, MKI G09B 9/00, “Automated training complex for training crews of ships "According to the patent of the Russian Federation No. 2234138, MKI G09B 9/06).

Known simulators contain workstations or mock-ups of operator workstations, workstations for training managers, computing tools, exchange tools and provide automated training and control cycles in a dialogue mode.

These simulators do not contain tools to simulate and display the external environment, which limits their scope, because for the effective training of vehicle personnel, such as flight personnel or operators of ship and submarine control systems, the presence of environmental models is necessary.

A device for performing a training flight according to the patent of the Russian Federation No. 2156501, MKI G09B 9/08 with means for displaying booth visual information, the real controls of which are connected via a pairing device to a computer that provides all training modes for a single or group flight.

Because all operations on modeling and signal processing are performed by one computer, the device is not reliable enough, and the use of real controls as part of the device limits its scope.

The closest in technical essence and adopted for the prototype is an integrated simulator of an aircraft according to the patent of the Russian Federation No. 2280287, MKI G09B 9/02, 9/08, built on the principle of distributed computing based on the representation of objects with the ability to quickly change its configuration.

The prototype device, as well as the claimed one, contains an instructor block, a database block, a vehicle system modeling block, a vehicle behavior modeling block, a simulator task manager, a model presentation and visualization tools block, and a simulator configurator connected to the simulator task manager, and a set of on-board equipment, interconnected with the vehicle systems simulation block.

The famous simulator is designed to train pilots of an air tool. Using it to train personnel of other vehicles, such as ships or submarines, is not effective enough, because visualization tools (visual presentation unit and visual presentation unit) form a visual environment that is the same for all students.

The technical problem solved in the claimed simulator is the ability to create for each learner a visual environment adequate to the real one and formed taking into account the specific task being worked out and the learner’s location on the simulator, which is an imitation of his real location on the ship (bridge, cabin, etc.) .

This problem is solved in that in an automated vehicle simulator containing an instructor block interconnected with a router, a database block, a vehicle system modeling block, a vehicle behavior modeling block, a simulator task manager and visualization tool, as well as a simulator configurator connected to the dispatcher simulator tasks, and a set of on-board equipment, interconnected with the vehicle systems modeling block, a manual control block was introduced a unit, a dynamic environmental modeling unit, a tactical environment modeling unit and a visual model tuning module, and visualization tools contain visual model blocks according to the number of trainees, each of which consists of sets of visual presentation modules of a fixed viewing sector and visual presentation modules of a fixed viewing sector, at the same time, the manual control unit, the dynamic environmental modeling unit, the tactical environment modeling unit, and the n module building visual models linked to the router, and the output adjustment module is connected to the simulator configurator.

This embodiment of the simulator allows you to expand its scope and improve the quality of staff training.

The complex simulator contains (Fig. 1) a vehicle equipment set 1, an instructor unit 2, a database unit 3, a vehicle system modeling unit 4, a vehicle behavior modeling unit 5, a manual control unit for tactical environment objects 7, a tactical situation modeling unit 6, the block of the dynamic simulation environment 8 blocks visual models September ₁ -9 _m, adjustment module 10 blocks visual models configurator simulator 11, the controller 12 of training tasks, marshrutiz Torr data packets 13 containing exchange units 14.

A set of on-board equipment of the vehicle 1 can be performed, for example, in the form of simulators of on-board equipment on touch monitors placed in a volume that simulates the student’s real working location. The instructor block 2 is designed to control the simulator blocks, change parameters and can be performed similarly to the prototype simulator trainer block. Database block 3 is intended for storing the totality of databases necessary for the formation of model, visual, and, if necessary, other system representations of objects. The vehicle systems simulation module 4 provides simulation of the operation of on-board systems and on-board equipment. The vehicle behavior modeling unit 5 provides modeling of the dynamics of movement (course, speed, onboard rolling, pitching, etc.). The manual control unit 6 provides real-time support for dynamic manual control of tactical objects. The tactical environment modeling block 7 simulates the presence and behavior of moving (floating) objects and dynamic coastal objects, and the dynamic environmental modeling block 8 provides a simulation of climatic conditions, the effects of wind, tides, currents, changes in the time of day and time of year. Simulation blocks 4, 5, 7, 8 can be made in the form of software modules based on universal computers.

Each block of visual models 9 consists of sets of visual presentation modules 15 and presentation modules 16 of a fixed viewing sector. Each block of visual models 9 is adapted to the tasks of the corresponding student, i.e. the number of blocks of visual models m is equal to the number of trained operators, and the number of modules 15 and 16 in each block of visual models is determined by the required field of view for each trained operator.

The simulator configurator 11 assigns training tasks and parameters and distributes them into blocks. The manager of training tasks 12 is used to transmit training exercises in the assigned blocks. Tuning module 10 provides an operational change in the parameters and characteristics of tactical environment objects. Each visual presentation module 15 of the fixed viewing sector contains (Fig. 2) a switch 17, a unit for generating parameters of a visual model of the physical environment 18, a unit for generating parameters of a visual model of the tactical environment 19, a synchronization unit for combining the physical and tactical environment 20. Direct and feedback between blocks of the simulator is used to transmit information and to transmit receipts about working out teams.

The unit for generating parameters of the visual model of the physical environment 18 is designed to generate environmental parameters in a given viewing sector for a time t _i and can be built on the basis of several specialized single-board microprocessor devices that synchronously and parallelly execute the same microprogram with different sets of source data. The synchronization of calculations, the formation of a set of input data for each microprocessor device and support for interaction with the switch are carried out by a special microprocessor device with supervisor functions.

The unit for generating parameters of the visual model of the tactical situation 19 in a given viewing sector for a time t _i can be built on the basis of a specialized multiprocessor computer. The multiprocessor kit implements the principle of matrix computing based on special processors with the same type of microprograms. The synchronization of calculations and support for interaction with the switch 17 is carried out by a special microprocessor device. The synchronization unit and combining the physical and tactical environment 20 can be implemented on the basis of a single-board single-processor microcomputer with a simplified set of commands. Hardware interaction with the switch 17 is carried out by a specialized microprocessor module.

The switch 17 is designed to provide direct pairing of the instructor block 2 and the tuning module 10 with block 18 and block 19. According to their functional value, the simulator blocks form:

- a group of jobs for students (a set of simulator on-board equipment 1 and a unit for modeling systems of a vehicle 4);

- a group of operational management of the training (instructor unit 2 and manual unit for managing tactical environment objects 6);

- a group for the formation of a visual model of the environment (a set of blocks of visual models 9 ₁ -9 _m );

- the simulator settings group for the required type of training (tuning module 10, simulator 11 configurator, simulator tasks manager 12).

The presentation modules 17 can be made in the form of known electronic or optical means for displaying information (display, projection screens, etc.).

The inventive simulator works as follows.

The instructor from block 2 sets the list of training tasks and carries out input of the initial data for the training. The instructor unit 2 implements the instructor interface during initial input of training data into the tactical environment modeling unit 7 and the environmental unit 8 and their correction, and using the manual control unit 6 the instructor carries out operational adjustment of the movement parameters of tactical environment objects for transmitting the corrected data to the unit tactical environment modeling 7. Interaction in real time between all the simulator blocks is carried out through exchange blocks 14 of the router 13. D Then, using the current information from the group of students' workstations, the instructor from block 2 sets up a group of blocks for modeling dynamically changing situations (blocks 3, 5, 7, 8), data on the general situation from which are intended for visual presentation modules 15 ₁ -15 _k , return to the instructor unit 2 (Fig. 3, Fig. 4).

When setting the type of training with the instructor unit 2, the configuration module 10 implements the instructor interface in accordance with Fig. 5, the simulator configurator converts the settings of the configuration module 10 into the simulator configuration matrix, and the simulator task manager 12 generates control commands into a group of students' workstations based on the changed configuration matrix (in blocks 1 and 4), in the tactical environment modeling block 7, in the environmental modeling block 8. Control information from the simulator task manager 12 is returned to us module Royko 10 for subsequent dispensing into blocks visual models September ₁ -9 _m.

The visual presentation is organized as a discrete process, when for each simulated current time moment t _i (where t _i = t _i-1 + Δt; i = 0, 1, ...), a set of process characteristics for each viewing sector is generated by the visual presentation modules 15. For each fixed sector of the review, the corresponding visual presentation module 15 generates a set of data for displaying (presenting) the map, moving objects, environmental characteristics and other "pictures" characterizing the situation in this sector. The review sectors form a visual scene containing n sectors, where n can take a value from 1 to values that provide a panoramic view. Each sector of the view is set by the coordinates of the point of view, the angle of view and the direction of view.
