Description

The utility model relates to the field of simulators and is intended for use in space simulators and simulators of manned spacecraft (PS) when preparing cosmonauts to work with an optical sighting system of a special complex (VSK-4) of a manned transport spacecraft (TPK), which provides control during orientation TPK, as well as docking and undocking of the TPK with the ISS.

To ensure that the cosmonaut-operator exercises professional skills in working with VSK-4, it is necessary that the training version of the VSK-4TI sighting device, together with other parts of the external visual environment simulation system (SIVVO) of the TPK simulator, provide the formation and display of a color dynamic image of the external visual the situation corresponding to the observation conditions in the VSK-4 TPK "Soyuz-MS" reticle in flight, including in terms of modeling the process of image focusing in the reticle.

There are a number of patents devoted to systems for simulating the external visual environment of simulators: U1, G09B 9/08, 2004; RU 44403, U1, G09B 9/08, 2004; RU 2325706, C1, G09B 9/08, 2006; RU 2299471, C2, G06T 17/00, 2005.

Despite the different target orientation of the considered devices, their common drawback is the lack of technical capability to simulate the image of objects on the earth's surface, corresponding to the conditions of their detection, recognition and registration using onboard surveillance equipment.

Known visualization system - patent RU 2325706, C1, G09B9 / 08, 2006, intended for use in space simulation stands and simulators. This system provides imitation of the external visual environment in the fields of view of the VSK optical sighting device, which is part of the onboard facilities of domestic space TPKs. The technical principles of constructing a simulator version of the VSK-4T sighting device from this patent cannot be used to solve the problem of modeling image focusing in the sighting device of a special complex of the TPK space simulator, since VSK-4T does not have optical elements moving during operation that affect the focusing of the image, i.e. e. the image in the sight is focused at all stages of the flight, which does not correspond to the actual operation of the VSK-4 during the flight of the Soyuz-MS manned transport spacecraft. According to ["Optical-visual devices of the transport manned spacecraft" Soyuz-MS ", Textbook of the FSBI" Research Institute of the CTC named after Yu. A. Gagarin "2015, p. 15]: from 30-40 meters, when the TPK approaches the orbital station, it becomes necessary to focus the target image on the screen using the EKRAN handle of the VSK-4 sighting device.

The closest in technical essence to the proposed utility model is a well-known prototype - an optical interface device (UOS) of a sighting device of a special complex of an integrated simulator (CT) TPK "Soyuz-MS" - TDK7ST No. 3 [UOS VSK CT "Soyuz-TMA" (TDK7ST No. 3 ), Operation manual STIK.791493.018 RE, AVIAKOM LLC, 2004]. UOS VSK, taken as a prototype, is a product that includes: a VSK-4T1 sighting device with a support, a base with a stand, a platform for placing UOS elements and a video projector, an optical interface device for a visual environment simulator of a VSK-4 sighting sight. The main task of the UOS VSK is to present the image of the external visual environment to the cosmonaut-operator, formed by the computer image generation system (CGGI) in order to teach him how to work with the VSK-4 sighting device.

The product, taken as a prototype, provides the instructor with information about the position of the "SCREEN" and "CENTER SVETOF" handles. This information from the product goes through the interface and exchange device to the computer system of the space simulator. The computing system of the space simulator, after processing the received information, sends it to SKGI, which generates a signal for the UOS VSK TDK7ST projector # 3.

The disadvantage of the product taken as a prototype is the impossibility of full-fledged modeling of the image focusing process in the UOS VSK TDK7ST No. 3. When the "SCREEN" handle is moved, the handle position signal is removed, which is proportional to the parameter of the potentiometer mechanically connected to it. With the introduction of a moving lens during the rotation of the "SCREEN" handle, an additional compensating signal about the position of the lens is introduced. There is also no information for the instructor about the operator's work with the shutter from the SHTORKA handle and a peripheral filter (hereinafter referred to as the “Light filter”) from the LIGHT FILTER PERIFER handle.

The technical task of the proposed utility model is to provide the possibility of modeling the image focusing process with the VSK-4TI sighting device, depending on the position of the output screen lens (with the EKRAN handle) and the distance to the object (in the area up to 40 meters), as well as providing the instructor with information about the position of the curtain from handle "SHTORKA" and a light filter from the handle "LIGHT FILTER PERIFER".

The technical result achieved when using the utility model is to expand the functionality of the simulators of manned spacecraft when preparing cosmonauts for solving problems using the VSK-4 as the main visual aid for manual motion control of the Soyuz MS the device introduced an image focusing compensator for the central field, an image focusing compensator for peripheral fields; a focusing compensator control unit, and a moving lens, an output screen shutter position sensor, and an output screen light filter position sensor are introduced into the output screen.

Included in the structure of the space simulator TPK "Soyuz-MS". Represents a hardware and software complex, standard manufactured by the industry. Signals from the USO of the space simulator 18 arrive at its input, and from the output the signals are sent to the SKGI 1.

The device operates as follows.

In the process of training, SKGI 1, on commands from the aircraft of the space simulator 19, in real time forms three-dimensional dynamic plots of the external visual environment for several means of observing the simulator. One of these means of observation is the training version of the VSK-4 sighting device - the sighting device of a special complex in the training version VSK-4TI for simulating the focusing of the image on the space simulator of a manned transport spacecraft. SKGI generates an image for the central field with an overlay image for the peripheral fields.

From the output of the imager, the video signal goes to the HDMI input of the projector 3. Projector 3 reproduces the image of the external visual environment and projects it onto the beam splitter 4.

The beam splitter 4 provides the formation of two streams of the image from the projector 3 for the central field and the peripheral fields of the VSK-4TI. The ratio of luminous intensity when dividing the luminous flux is selected after calculating the entire optical scheme of the sighting device of a special complex in the training version VSK-4TI for modeling the focusing of the image on the space simulator of a manned transport spacecraft.

From the beam splitter 4, the separated light fluxes enter the input of the image focusing compensator for the central field (CP) 5 and the image focusing compensator for the peripheral fields (CP) 6. The compensators 5 and 6 are optical-mechanical units. To control the focus of the compensators, high-precision drives are used, controlled by the focus compensator control unit 7.

The control unit for focus compensators 7 provides a parallel calculation of the control parameters separately for each image focus compensator 5 and 6 on the basis of information coming from the lens position sensor of the output screen 15.

The linear movement of the lens of the output screen 8 when the "SCREEN" handle is rotated does not lead to defocusing and geometric distortions of the image in the CPU and PP. This is achieved by using image focusing compensators 5 and 6. In the standard VSK-4, rotation of the EKRAN handle leads to defocusing of the image at a distance to the target of less than 40 meters.

Modeling the process of focusing the image in the sight of a special complex in the simulator VSK-4TI for modeling the focusing of the image on the space simulator of a manned transport vehicle is carried out by means of SKGI 1 according to commands from the aircraft of the space simulator 19

An analog signal from the position sensor of the moving lens 15 is fed to the input of the USO of the space simulator 18. This signal is digitized with subsequent transmission to the aircraft of the space simulator 19.

The calculated focusing parameter is transmitted from the aircraft of the space simulator 19 to SKGI 1 to apply the "defocus" effect to the generated image.

Analog signals from the shutter position sensor 16 and the light filter position sensor 17 are fed to the input of the USO of the space simulator 18. These signals are digitized with subsequent transmission to the aircraft of the space simulator 19.

Depending on the parameters of the signals from the position sensors of the moving lens 15, the shutter 16 and the light filter 17, commands are generated in the VS 19 and transmitted to the SKGI 1. In the SKGI 1, objects corresponding to the size and position of physical objects in the VSK-4TI are superimposed on the output image. This image is fed to the instructor monitor 2 to monitor the operator's actions.

The advantages of the proposed scheme for modeling the process of focusing the image in the sight of a special complex in the simulator version VSK-4TI for modeling the focusing of the image on the space simulator of a transport manned spacecraft over the known one, expanding its functionality, are:

1. The use of a moving lens 9 and image focusing compensators 5 and 6 in the VSK-4TI sighting device to provide the operator with a real image on the output screen.

2. Presentation to the instructor of information on the position of the shutter and the light filter for the instructor to control the operator's actions.

Thus, the proposed useful model eliminates the shortcomings of the well-known scheme for constructing training variants of the VSK-4 sighting device for the space simulator of a manned transport spacecraft, and its use makes it possible to expand the functionality of the manned spacecraft simulators when preparing cosmonauts for solving problems using the VSK-4 sighting device.
