Description

FIELD OF THE INVENTION

The invention relates to educational and training tools and can be used in simulators of weapons, military and special equipment to simulate a circular hull environment.

State of the art

A projection system with support for 3D images is known from the prior art (patent RU 136221, IPC G09F 13/00, published December 27, 2013), including a screen, using a high-contrast and translucent film as a screen, direct, reverse or double-sided projection, made with the possibility of it application to a flat and / or curved surface with antistatic properties, a projector with 3D image support, optically connected to the screen, built-in or connected via an interface, USB Flash drive connected to the projector, wireless W An i-Fi router (router) connected to the projector for organizing remote access, audio playback devices, both built-in and external, connected to the projector.

Also known is the cultural interactive panorama (culture) (patent application RU No. 2006135228, IPC G09F 19/18, dated February 26, 2005), which is a system for displaying interactive computer programs on a large area using nine flat screens to build one seamless specialized screen.

The disadvantages of the presented analogues is the lack of a screen in the form of a cylinder and a sphere.

Disclosure of invention

An object of the invention is the creation of a screen complex that provides the following viewing angles from the center:

a) cylinder:

- 360 degrees horizontally;

- 180 degrees vertically;

b) scope:

- 180 degrees horizontally;

- 110 (from -55 to +55) degrees vertically.

The technical problem is solved by attaching segments of the cylindrical and spherical screens, the fixed installation of the information display system (video projectors), the frame and the dimming system (tent on the frame).

The features used to characterize the methods

The frame is a spatial structure consisting of flat trusses and tubular braces and struts. Vertical racks with supporting surfaces form a cylinder with H = 2700 mm and R = 3050 mm along the rear supports, and in the screen area a cylinder with R = 2800 mm or a sphere with R = 3200 mm. Between themselves racks are fastened with an upper belt of steel thin-walled pipes. At the bottom, only racks that are not involved in fixing the cylindrical screen are likewise unfastened.

Cylindrical and spherical screens is a modular design consisting of separate sections. Each section is a segment or petal that provides viewing angles and the implementation of the presentation of the information provided that meet the requirements of a three-dimensional visualization of a circular cushion setting. Segments, petals are three-layer panels with a momentless connecting edge. The outer and inner cladding sections are made by hand laying out of glass reinforcement (fiberglass sheets impregnated with epoxy resin), followed by heating under pressure (evacuation). Sheathing sections are assembled from 3 layers of fiberglass. The working surface of the screen is painted with a special two-component matte paint (Fig. 2).

The roof of the frame is made of the same as the rack of the truss, converging to the center of the cylinder (Fig. 2). In the center, ceiling trusses are interconnected. At the other end, the ceiling trusses are mounted on the upper triangular rack brackets.

To mount the projectors on the screen frame, platforms are organized (Fig. 3).

The appearance of the frame, methods of terminating the supports of the design scheme, the direction of action of the main external loads (equipment 100 kg, lateral random exposure 50 kg) are presented in FIG. one.

The information display system is built according to a multi-channel scheme, where each channel has its own display means with a resolution of at least 1920 × 1200 pixels. As projectors, digital projectors are used, working on a common screen of cylindrical and spherical shapes. Each digital projector is designed to display on a certain area of the screen a part of a three-dimensional image of the downstairs environment in accordance with the characteristics of the digital projector (corners of the display field) (Fig. 3).

The implementation of the invention

Screen complexes are installed in a building constructed according to a standard design or in other buildings and premises that ensure compliance with operational documentation requirements for simulators.

The screen complex should be operated in the conditions presented to group 1.1 of the climatic modification of UHL for equipment intended for installation in constantly heated rooms and structures in accordance with GOST.RV 20.39.304 with:

- air temperature from plus 15 ° C to plus 27 ° C;

- relative humidity - not more than 80%;

- dust content - not more than 0.075 mg / m ³ .

The composition of the screen complex:

- constructive mounting of the screen (screen sections) and projectors of the screen complex (frame);

- cylindrical and spherical screens;

- dimming system (awning on the frame).

Claims (1)
