The PCR is a Central element of BOOD and represents serially produced a powerful processor module industrial standard (specializirovanoy the PCR generated separately under specific development of BOOD and having all the necessary interfaces for interfacing with BA KA and BRA, but the creation of such a PCR extremely costly task, in addition, it should additionally be certified to determine the possibility of its application in kosmicheskoy technique), having an internal Tina (local highway such as PCI, ISA, or other).

The PCR manages SCONCES, software collection service and scientific information with LAMPS according to the program of measurements encoded in name permanent memory (EPROM) of the PCR, the data record in memory the PCR and pre-processing of information and its output either the BLT through interfaces such as Serial ATA, or BA KA through its own high-speed interfaces (Ethernet, USB, and others), or the first transfer of such information through the LM to the CA (if the PCR does not possess the necessary high-speed interfaces for information transfer in BA KA), and then in BA KA via high-speed interfaces MUSTACHE (LVDS, SpaceWire, and others).

The PCR usually consists of the following main elements: CPU, memory, network controllers, Ethernet, video, serial ports RS422/485/232, USB ports, soldered flash disk, standard parallel port (LPT), Serial ATA, watchdog timers, etc.

To meet the requirements of the appointment of BUT uses established in the PCR operating system real-time (RTOS) QNX type with high reliability in networked applications, and to achieve full compatibility with, for example, RTOS IUS Russian segment (PC) of the International space station (ISS), th is allows you to effectively communicate (exchange data requests) at the server level ICS PC ISS, BUT (for example, in the known system "server"to"client").

US extends BUOD, providing interfaces for sharing with SCONCES that are missing in the PCR.

The CA accepts SCONCE scientific information (NO) in the form of digital arrays through the channels of the CRPD and transmits it in the PCR on LM.

The US has its own memory for holding, if necessary, buffering ANY received in CONDITION of the BRA (buffering occurs when the LAMP is operating in mode high downloads and LM is unable to cope with large data stream).

The CA communicates between BRA and BUT but channels SKU: SCONCE comes KU and IPM, and BRA - response (receipt) received in BRA KU.

The CA communicates between BUT and SUBA (IUS) of the CRPD, implemented on a high-speed interfaces such as LVDS, SpaceWire transfer (CM) and service channels SKU implemented PA interfaces RS422 or CAN. Through the channels of the SSI of the IUS in CONDITION receives KU and IPM, and from US in IMS - responses (receipts) received in CONDITION KU, and also service information that shows the status of telemetry parameters BUT.

The need to use an independent (from the system processor DIC) Autonomous timer unit (ATU), controlling periodic software devices is dictated first of all, the possibility of occurrence of facts "hang" (loops) of micropr is cessaro due to single failures, having, as is known, nonzero probability. At the same time, the ATU can put the data acquisition system code relative system time with an accuracy of 0.1 µs. Thus, secondly, the ATU is intended for binding-time logging of events to a timestamp issued by the information management system (IMS) CA.

STCC takes from SUBA KA for individual feeder side voltage of the power supply 28 has internal protection against incorrect connection of the poles of power and short pulse inrush current of 10 A, and performs filtering (blocking) input power from the electrical interference as the load side connected to the feeder supply, and Vice versa, from BUOD.

STCC discrete (relay) team management (CGS) from SUBA KA and translates them into US and SCONCES. In the chain of commands used power ±28,5, served in BUOD and respectively in SCONCES on independent tin supply. Teams do g in BUOD/SCONCES on the control winding of the relay dubbed "dry" relay contacts. Parallel to the commands for actuating the contacts of the relay is energized catering to 28.5 In that upon actuation of these relays is supplied to the load and generates a constant current load (electronic assemblies BUT/BRA). The passage of all CGS confirmed receipts (feedback or suggestions is BU OD/WALL for passing RKU), issued by BUOD/SCONCES on discrete telemetry channels of SBI through relay contacts (CU) Tina "dry contact". In this case, the load current in the external circuit is limited to the value of 10 mA (at closing normally open contacts). Additionally, receipts duplicated and served on the US as the format of the status register commands (STK). Part SCCRP to control voltage 5 V supply includes one sensor Tina EC (electronic key). Additionally STCC issues in the SBI KA information with telemetry sensors (TM sensors) BUT (CU - relay, TD - sensor, EK - e key) and BRA (CU - relay, TD - sensor, EK - e key, AD - analog sensor KS - control dock).

The main function of bspd - receive data in the form of digital arrays (CM) information from the PCR but synchronous data transmission channel (after pre-processing the PCR and compression), buffering them in its own memory for subsequent transfer to SBI KA for operational discharge of pas and Land analysis.

PSU is intended for:

- production of primary flight catering, filed in STCC the feeder power by feeding on STCC corresponding CGS, the secondary supply voltage for powering US, OPK, ATU, bspd, as well as the internal bus of the PCR (local highways PCI, ISA, or other);

- stabilization of nominal power and their primary filtering of electronic the historical noise and interference.

The BLT is necessary if you want to store the information, the amount of which exceeds the amount of storage (buffering) of the staff posted in the composition of the PCR. Part of the BLT can enter, as well as removable media such as, for example, a set of interchangeable solid-state IDE media up to 256 GB each, which allows continuously and very quickly (two orders of magnitude faster than writing to internal flash memory) to record useful events (digital arrays of scientific information) when working SCONCE in high downloads detectors (at frequencies operation at 1 MHz and above).

With the increased consumption of electronic systems BUAD (for example, if the PCR consumes more than 12 watts) and his work in the dash compartment AC in ambient temperature of 30°C and above, to achieve the desired temperature on the surface of fuel elements in BUT along with heatsinks for conductive heat transfer at the building, used the forced cooling system (STRs) on the basis of fans working in "hot standby" mode, providing by blowing air circulation and increase cooling efficiency.

The proposed structure of a distributed system of data collection and obrazovky data with on-Board recording equipment has the topology of a star, in the centre of which is BUOD, and at the ends of the Lu is she there are various Tina onboard recording paragary, each of which is associated with BUOD their separate communication channels (based interfaces RS422/485, LVDS and other)transmission of scientific information concerning only this BRA that ensures each SCONCE flows transmitted in BUOD information and flexible operational management system BRA.

A typical algorithm SCONCE with BUOD below.

Detectors SCONCES are a source of experimental data (a set of signals)received via the interface (a set of registers) but logical and amplitude measurement channels (number of channels, each WALL may be different) in electronic modules BRA, where they are converted into digital data that arrive at the output interfaces SCONCES, which are composed of controllers that control the collection and transfer of the formed arrays of scientific and housekeeping data but the CRPD and SKI. This BRA includes: the Registrar information (detecting device) and the system of collection and prior ilen information processing (ussf), designed for reception of digital data logger information SCONCES, filtering useful information, packaging it in digital arrays (CM), intermediate buffering of the CM and their transmission via communication channels in BOOD.

Controllers N channels have also rises the e buffer (stack) drives for in order not to stop the set generated for transmission in CONDITION of BUOD arrays during signal inhibit, for example, Ni, caused, for example, by the fact that the current drive arrays of Ni in the channel BLT, BUT overflowed, and parameteres on a new (free) drive, or due to the fact of a system failure. The signal of the ban will be issued by SKI from OPK BUT engaged in the accumulation of information in the BLT with periodic parametervalues (switching) drives ("disk"). In the absence of a signal of a ban on the transfer, free high-speed channel _N are reset information from _N in BUT, where it is temporarily stored on floppies" BLT until that point in time, when the available resource of the PCR allocated for pre-processing "_N", in which is formed an array of concise scientific information to be output in real time through bspd the student business incubator (Kapal telemetry). Simultaneously with the layout of the arrays for output in the student business incubator, as well as uncompressed arrays in ICS, the PCR collects information from service systems and generates arrays of official information which teams from SUBA can be transmitted separately from the array of scientific information (for example, to estimate the health parameters and BUT and BRA). All data formats in arrays of information and is bound to labels on-Board time generated by the ATU. Additionally ATU, in case of a failure ("hang") in PCR, it restarts ("soft restart"), while maintaining the status of the restart in the service register to identify possible failures in information incurred when the system is restarted, despite the fact that all N-channel arrays are set automatically signals the ban.

Thus, during normal (malfunction-free) slave remote system always has a definite correlation between the performance of BOOD (input, processing, storage, output data) and the flux density of the input information, are currently in the buffers SCONCE subject to transfer in BOOD. This ratio is chosen deliberately, based on specific objectives, and determines a specific structure and execution of the nodes BUT and BRA. However, the overall structure of the system (1) is not changed, it is obviously somewhat redundant (as, for example, for the case when you need increased performance of the PCR, which can have a power consumption of more than 10 W, which requires the use of STRs).

An example implementation of the proposed system on the ISS is shown in figure 2.

ON consists of two BRAS (Multiview camera shooting and block photodetectors)that are outside TH and having in its composition a separate ussf. ON connected with the control unit and data acquisition (what WAD), located in the city, and communication between the ussf each SCONCE, BUT occurs through the channels of the SSI and KPI implemented based interfaces RS422 and LVDS, the above algorithm SCONCE with BUOD.

This circuit implementation can significantly simplify the interoperability of service systems ISS every single BRA, laying accumulation functions and data pre-processing compression and culling images coming from a SCONCE on BUT.

The above outlines the main features of the control system of collecting and processing suburban with on-Board recording equipment spacecraft, but the person skilled in the art it is obvious that on the basis of disclosed data, you can create many variations of a similar system, the scheme of which are disclosed in this application, and which will have other electronic components, but perform similar functions disclosed.

SUBSTANCE: method creating an audio scene for an avatar in a virtual environment comprises the following steps: creating a link structure in a virtual environment between a plurality of avatars; reproducing an audio scene for each avatar based on its connection with other avatars connected by the links; wherein the created link structure is configured to determine the angle for reproducing the audio scene and/or the attenuation coefficient for applying to audio streams on input links. The angle for reproducing the audio scene corresponds to angles of links between said each avatar and other avatars connected by links; the link structure includes a minimum spanning tree. Loops are introduced into the minimum spanning tree such that the minimum length of the loops is shorter than a predetermined value so as to prevent echo in the reproduced audio scenes.

EFFECT: solving a task such as creating voices which really seem to originate from avatars in a virtual environment.
