In particular, the proposed invention can be used on board an aircraft, ships, space systems, as well as any real-time ground technological objects.

An analogue (prototype) is known from the prior art - a real-time information transmission system based on an all-optical spectral-densified onboard real-time network (RF patent No. 2694137, publication date 07/09/2019), which contains at least two computing modules, in which operating software applications, an optical communication line, an optical multiplexer and an optical demultiplexer, a spectral network terminal containing transmitting and receiving optical modules.

The disadvantage of this system is the presence of only one level of information exchange in the network, which leads to a decrease in the reliability of information exchange between onboard systems.

The technical result of the proposed invention is to improve the reliability of information exchange between onboard systems in real time with guaranteed message delivery.

1. The specified technical result is achieved due to the fact that the real-time information transmission system based on an all-optical wavelength-dense on-board network contains at least two computing modules in which software applications operate, an optical communication line, a spectral network multiplexer consisting of optical amplifiers, a network optical multiplexer, optical splitters, a spectral network terminator containing transmitting and receiving optical modules and is characterized in that a transceiver optical module is additionally included in the spectral network terminal, which contains optical transmitters, an optical splitter, an optical demultiplexer, an OADM module, optical receivers of the general information of the computing modules, optical receivers of the computational module's own information and the transceiver controller, in which the output memory area is organized, while the transceiver controller is connected to the optical the general information receivers of the computational modules, which are connected to the optical splitter through the optical demultiplexer of the transceiver module, and also the transceiver controller is connected to the OADM module through the optical receivers of the computational module's own information and the optical transmitters of the transceiver module.

When designing the organization of a real-time information transmission system for an aircraft, it is necessary to pre-form a list of all on-board systems 1 and sensors 4 of the on-board equipment complex (OBE) involved in exchange operations and connected to the real-time information transmission system.

Next, a list of software applications operating in each of the computing modules 2 of the on-board systems from the OBE and in the sensors 4 participating in the exchange of information is formed, dividing them into two groups: the first group includes the total number of software applications transmitting information l _out , the second group includes the total number of software applications that receive information l _inp (in the general case, l _inp ≤ l _out ).

After that, a general list of software applications is formed that transmit information throughout the OBE - L _out .

On the basis of the lists formed earlier, the truth of the ratio L _out ≤ λ is established, where λ is the maximum number of WDM channels in the optical network of the information transmission system in real time. If the ratio
L _out ≤ λ ^{О is} true, then go to the establishment of a correspondence (distribution) between specific l _out (individual systems) and λ. If the ratio L _out ≤ λ ^{О is} false, then one goes to time-division multiplexing, which consists in assembling messages from various software applications operating in the computing modules of on-board systems from the OBE into a sequence of transmitted data over one λ-channel.

In the spectral network terminal (SSO) 3 of each on-board OBE system, the total number of output λ-channels is determined. For example, for airborne system A, the WDM is defined as:

λ^AND _out = U {λ^AND _one…. λ^AND _n},

with its own set of wavelengths characteristic only for this SSO 3, this on-board system 1 OBE and this list of software applications. There are two possible approaches to the formation of λ _out .

The first approach is based on a pre-selected ready-made component base of a real-time information transmission system, namely, on selected transmitting optical modules corresponding, for example, to a wavelength-multiplexed group of channels λ^AND _out , as well as on optical multiplexers that form a wavelength-multiplexed stream as for each onboard system, for example λ^AND _out , and combining into a common channel, with wavelength division multiplexing of all output channels from each onboard system: λ^ABOUT _out = U{ λ^AND _out …. λ^N _out } ...

The second approach is based on the possibility of software tuning of each group of optical components in each component of the OBE to its own output group of wavelengths (for example, λ ^N _out ). This means that for implementation it is necessary that at the level of the device responsible for the formation of the optical signal (transmitter) there is a possibility of programmatic control of the value of the output optical wavelength.

The first approach has a real technological component base. The second approach, more promising, but at this stage is significantly limited due to the impossibility of making adjustments over all wavelength ranges required to cover the entire set of output channels λ _out , for large amounts of λ _out .

^{Next, the total number of input λ i} _inp is determined in the SSO 3 of each on-board system 1 OBE, with its own set of wavelengths characteristic only for this terminal system, this component of the OBE and this list of software applications. In this example of implementation of the invention, an approach is used, which is based on a pre-selected ready-made component base of an optical network, namely, an optical demultiplexer that receives and demultiplexes the wavelength-multiplexed channel λ ^О _out to obtain at its output a group of separate optical λ _inp channels necessary for the operation of this systems (for example, λ ^H _inp );

At the physical level, the proposed invention uses a fully optical on-board information exchange network based on wavelength-division multiplexing (WDM) technology, and at the information level, a distributed shared memory (DSM - Distributed Shared Memory), with which each computer the system is provided with copies of the memory of all other computers.

Wavelength division multiplexing (WDM) allows information to be transmitted over multiple independent channels, on optical waves of different lengths, over a single optical fiber.

The general logic of the operation of a two-circuit system for real-time information transmission based on an all-optical spectrum-dense onboard real-time network is explained below (Fig. 1).

The proposed system for transmitting information in real time contains two parallel operating circuits of information exchange, implemented in the form of two optical network topologies.

Each of the sets of software applications of on-board systems 1, forming the output data P ^out, is associated with one fixed wavelength λ _i along which this software application will transmit information, and a memory area

Each SSO 3 is a spectral network device and provides OBE access to the information transmission system based on the distributed memory principle (DSM-memory) and consists of a transmitting optical module (POM) 8, which includes:

transmitting controller 16, optical transmitters 11.2, optical multiplexer 17, as well as from the receiving optical module (PROM) 7, including: receiving controller 15, optical receiver 10.3, optical demultiplexer 12, as well as a transceiving optical module (PPOM) 6, including in itself: transceiver controller 9, optical transmitters 11.1, optical splitter 13, optical demultiplexer 12, OADM module 14, optical receivers 10.1 of the general information of the computing modules and optical receivers of the computational module's own information.

Each SSO 3 is connected via the system interface bus to the computing module 2.

Each transmitting controller 16 generates a data packet for transmission, encodes the data packet, transfers the data packet to the output memory area, built on the principle of a circular FIFO buffer.

This optical signal is fed to the optical multiplexer 17, which includes λ _i in the private wavelength-multiplexed optical channel λ ^{C of} this onboard system formed by it. Ring buffer

cyclically transmits the received message to the optical channel λ ^C until the information is changed. The optical multiplexer 17 can be replaced by an optical splitter when implementing in the optical transmitter 11.2 ¬ the function of tuning to a separate wavelength by means of a control signal C _λТout .

Optical channel λ^Cfrom the output of the optical multiplexer 17 is fed to the input of an optical amplifier (not shown in the figure) of a spectral network multiplexer (CCM) 5. CCM 5 consists of: optical amplifiers, a network optical multiplexer, an optical splitter (splitter). If necessary, CCM 5 can consist of a network optical input splitter and an output optical splitter, a set of optical amplifiers, the need for installation of which is determined by optical calculation. An embodiment of such an implementation is shown in FIG. 3.

SSM 5 of all private optical channels coming to it at the input forms a common information optical wavelength-multiplexed data stream -λ ^O ... As part ofλ ^O channel data λ_i are supplied to all optical demultiplexers 12 of all onboard systems 1 OBE. Optical demultiplexer 12, which is part of the PrOM 7 of the spectral network terminal 3, depending on the settings, can either form at its output a complete set of optical signals included in a single channelλ ^O = Uλ_n, that is, all n-wavelengths, or selectively receive the group λ, to which this optical demultiplexer 12 is tuned. The optical demultiplexer 12 can be replaced by an optical splitter when the optical receiver 10.3 implements the tuning function to a separate wavelength by means of the control signal Cλ_Rinp...

Each SSO 3 additionally contains a transceiver optical module 6, which ensures the inclusion of an additional ring control optical network circuit (KUOSK) into the real-time information transmission system. The purpose of KUOSK is to transfer service information between the systems of the onboard complex. The optical transceiver module 6 consists of one transceiver controller 9, an optical splitter 13, an optical demultiplexer 12, optical transmitters 11.1, optical receivers 10.1 of the general information of the computing modules and its own information of the computing module 10.2 (the number of which coincides with the number of outputs of the input demultiplexer), the OADM module (Optical Add Drop Multiplexor), which provides the selection (drop) from the KUOSK of the common information optical channel of at least two wavelengths, and passes the remaining wavelengths further into the channel, as well as the input of the same wavelengths and their further passage in the common information optical channel ). Each transceiver controller 9, in which the output memory area is organized, is connected to the optical receivers 10.1 of the general information of the computational modules, which are connected to the optical splitter 13, through the optical demultiplexer 12. Also, the transceiver controller is connected to the OADM module 14 through the optical receivers of the computational module's own information 10.2 and optical transmitters of the transceiver module 11.1.

At the input of each receiving 9, transmitting 15 and transmitting 9 controller, control signals are received from the computing module 2 via the system interface bus, and the output of each transmitting controller 16 is connected to the inputs of the optical transmitter 11.2 and the optical multiplexer 17 by a communication line through which control signals are transmitted, and the output of each receiving controller is connected to the inputs of the optical receiver and optical demultiplexer 12 by a communication line through which control signals are transmitted.

In addition to the described logic of the CCO 3 operation, below is the purpose of the control signals Cλ (Fig. 2). These signals provide the ability to configure the operation of optical receivers 10.3, optical transmitters 11.2, optical multiplexer 17 and optical demultiplexer 12 to operate with different wavelengths λ _i circulating in the information transmission system in real time. The need to adjust the optical components of the CCO 3 to different wavelengths is determined by:

- a limited number of wavelengths used in wavelength division multiplexing (this figure ranges from 96 to 128, although there are publications that report working with 256 wavelengths);

- features of the mode of dynamic reconfiguration of the OBE onboard systems in case of failures.

Each POM 8 of each SSO 3, depending on the state, is controlled by the vector:

^Cm _{MTR ^{= {Cλ T1 out, Cλ T2}} out, Cλ T3 out ... Cλ Tn out},

where: Cλ ^T1 _out - control signal of the first optical transmitter 11.2;

Cλ ^Tn _out - control signal of n- optical transmitter 11.2.

Since each component of the control vector CCO 3 determines the output wavelength λ _i for a given one of the output n-channel, then for this vector the equality of the values of its components is unacceptable. It is also necessary to comply with the requirement that the intersection (logical "AND") of the sets of control vectors transmitting the components of different SSO 3 was empty:

,

,

where g is the number of SSOs.

Failure to comply with this requirement will lead to a violation of the operation of the wavelength division multiplexing.

The permissible set of control vectors C _MTR form a control matrix for the formation of output channels of optical transmitters 11.2, each row of which defines one of the possible sets of optical wavelengths for one of the MTR 3 of the computing module of the on-board system included in the OBE.

Accordingly, for the receiving optical module 7, the control vector of the receiving optical module is additionally introduced:

C ^R _{MTR ^{= {Cλ R1 out, Cλ R2}} out, Cλ R3 out .... Cλ ^Rn _out },

where Cλ ^R1 _out is the control signal of the first optical optical receiver 10.3;

Cλ ^Rn _out - optical n optical control signal
receiver 10.3.

This vector is subject to the same restrictions:

where g is the number of SSOs.

The logic of the MTR 3 will be as follows. The number of optical transmitters 11.2 in each MTR 3 consists of two groups:

+

T _cco =

+

Where:

T _CCO is the total number of optical transmitters in each CCO;

– базовый набор оптических передатчиков в каждом ССО;

- a basic set of optical transmitters in each MTR;

– избыточные (redundancy) оптические передатчики в каждом ССО.

- redundancy optical transmitters in each MTR.

The total number of optical transmitters 11.2 in the considered complex is respectively equal to:

=

+

,

=

+

,

where s is the number of onboard systems 1 in the OBE.

The total number of channels l ^c in the real-time information transmission system can be formed as:

- в этом случае к необходимому количеству каналов прибавляется дополнительная группа
л^к =

+

.With redundancy: l ^k =

- in this case, an additional group is added to the required number of channels
l ^k =

+

...

- в этом случае число каналов равно базовому, существующему, заложенному количеству оптических каналов.Without redundancy: l ^k =

- in this case, the number of channels is equal to the basic, existing, laid down number of optical channels.

Compliance with the principle of openness of the OBE architecture requires that the S value be taken with a margin for the possibility of increasing the OBE components.

Одновременно программное приложение, реализующее функцию мониторинга и управления бортовой сети, принимает весь набор длин волн Uλ_k, проходящих в кольцевой сети через оптический сплиттер 13. На выходе оптического сплиттера 13 образуется два равноценных канала, в каждом из которых содержится λ^RNG = Uλ_k.

is basic and can vary depending on the tasks of information exchange in the complex of onboard equipment.

In the ring control optical network circuit, each control word is allocated a separate operating wavelength - λ ^RNG i, where i is the number 2 of the onboard system.

The presence of two information spectrum-dense network circuits of information transmission allows two parallel processes to be carried out simultaneously:

- the actual information exchange;

- monitoring and control of the on-board network.

Due to the absence of the informational intersection of these contours, it becomes possible to use the same set of wavelengths in each of the informational contours, which makes it possible to exchange a larger number of software applications on a limited maximum permissible number of λ-channels.

Под «условной» избыточностью понимается тот ресурс КБО (вычислительные, сетевые и пр.), которые могут быть освобождены от выполнения своих функций без ущерба жизненно важным функциям управления летательного аппарата (ЛА). Логика динамической реконфигурации бортового оборудования в сети со спектральным уплотнением с избыточностью по сетевым каналам (

) is possible if work with "conditional" redundancy is allowed. By "conditional" redundancy is meant that OBE resource (computing, network, etc.) that can be released from performing their functions without prejudice to the vital functions of the aircraft control. Logic of dynamic reconfiguration of on-board equipment in a network with redundant WDM over network channels (

), runs as follows:

1. Based on the information transmitted in the ring

the control optical network circuit and as a result of the monitoring and control programs of the on-board network, a list of failed equipment is formed.

2. According to this list of failed equipment

a list of l associated with the failed equipment is formed.

3. A list of conditionally redundant optical

- reconfiguration of output optical transmitters 12.

5. Formed vector C ^R _{MTR ^{= {Cλ R1 out, Cλ R2}} out, Cλ R3 out ... Cλ Rn out},

and it happens:

- blocking of receivers in faulty equipment;

- reconfiguration of optical receivers 10.3.

The reconfiguration of the software applications and memory areas of the controllers that form the DSM memory, with which the corresponding software applications work, take place accordingly.

As can be seen from the above description, the real-time information transfer system formed in this way is free from a number of disadvantages:

- the exchange of information between onboard systems is carried out in real time with guaranteed message delivery due to the use in the proposed invention of spectral network terminals and a spectral network multiplexer, which form a wavelength-multiplexed stream that combines λ-channels;

- it is possible to monitor the state of on-board components and develop solutions for reconfiguring the complex of on-board equipment in case of failures;

- it becomes possible to reconfigure the on-board equipment complex in case of failures due to the use of spectral network terminals in the proposed system, which implement control of the formation of λ-channels both at delivery and at reception.
