Appointment of the main elements of the complex.

Four VCTS are designed to ensure the interaction of the control computer complex 10 with the primary and secondary network complexes and other interacting systems and ship complexes, as well as for the control and monitoring of radio communication means, antenna switches, for switching ACS to terminal equipment and radio communication means, etc. .

Computing control complex 10 provides automation of connection control processes in radio communication networks with a given correspondent, evaluation and selection of radio channels with the best parameters, dynamic control of radio channel parameters, monitoring of radio networks, the formation of communication paths according to applications, monitoring of the state of paths and hardware, etc.

Four VKTS have a two-level structure. Each level is designed to solve a certain range of functional tasks of the complex as a whole.

The first level is supported by a digital switching and control system and ensures the interaction of the control unit with the technical means (TS) of the ACS in terms of the formation of communication paths, control of the TS and monitoring their condition.

The second level is supported by an Ethernet-based local area network (LAN) and ensures the interaction of ship systems with the VCU.

The packet telecommunications complex 4 is designed to provide a stable closed and open exchange of various types of information in the ship-to-ship and ship-to-shore directions.

The command and signal information exchange complex 5 is intended for transmitting messages (formalized, non-formalized and non-structural) prepared at an automated workplace using the TKPS 4 product to the address of coastal control points.

The complex of technical means of data transmission 6 provides electrical and information-logical interaction with the integrated control system 10 of the ACS through an intracomplex transport network.

The automated complex for interaction and information exchange 7 is designed to ensure the reception and transmission of information via KB, VHF, DSC radio channels in the corresponding radio networks of interaction with the NATO Navy.

The general shipborne data exchange system 8 provides electrical and information-logical interaction with the integrated control system of the ACS through an integrated transport network.

Terminal equipment 9 is used for receiving and transmitting various analog and digital information.

Automated ship correction post 11 is designed to provide automated data preparation and fire control of ship artillery fire support ships.

Radio stations 12 are used to provide radio communication with the ship’s fire support post, with coastal KP, NK, LA in the KB, DCV / VHF bands.

Modem 13 provides automated data transmission from portable reconnaissance and target designation equipment (laser rangefinders, etc.) to the PAO KOP.

Automated workstation 14 with terminal KVOI 15 provides collaboration with primary and secondary network complexes and interacting ship systems, as well as automation of the processes of establishing and maintaining communications, processing subscribers' applications for the provision of radio channels and radio networks.

Consider the functional structure of KVOI 15. It is presented in Figure 3 in the form of a protocol profile. Letters in brackets denote the relevant annexes of the standards.

Figure 3 shows that the functions at the physical level are implemented by the radio equipment 12 and the modem 13. In terms of establishing and maintaining a physical connection at this level, there are also control functions and automatic link establishment functions. Radio equipment (RPDU, RPU, radio stations) 12 comply with the STANAG 4203 standard. And the modem complies with the STANAG 4285 and 4539 standards. A feature of their construction compared to known modems, in particular UPS KV4.8M, is that they are serial and monophonic, t .e. their signal-code designs do not provide for the formation of several subchannels in the working band.

The functions of the data channel level are represented by sublevels of the interface of the subnet of data exchange on radio channels, access to the channel, data transmission, and linear encryption.

The subnet interface sublayer represents a common standard interface to all users. The standard contains a detailed specification of the primitives that exchange between this sublevel and external users (clients) and protocol data modules (TIRs), which exchange over radio channels between sublayers of the subnet interface of various nodes.

The channel access sublayer provides additional functionality that is necessary with various forms of access to the communication channel. This sublevel supports the establishment of a physical and logical connection over a dedicated radio channel under the assumption that the processes required to establish communication at the desired frequency are controlled by procedures that are external to this standard and are not considered in it. MTD, which are exchanged over the radio channels by the sublevels of access to the channel of various nodes, are described in B to the standard.

The data transmission sublayer provides for the implementation of multiple data exchange protocols. These protocols provide for priority and non-priority messages both reliable data exchange by means of decisive feedback and non-guaranteed data delivery during broadcasting. MTDs exchanged over the radio channels of the sublevels are described in C to the standard.

The application also contains protocols for adaptive control of the data rate of the modem’s radio channels and other parameters when using signals defined by STANAG 4285 and 4529. The interface between this sublayer and the auxiliary sublevels located below (modem sublevel) is described in D to the standard. Also, the implementation of adaptation procedures for data transfer speed (for speeds of 1200 bit / s and higher, this, in fact, means simultaneous adaptation according to the signal-code design, which is “tied” to the data transfer speed), requires the implementation of operational control procedures for the modem. A minimum set of control commands is provided in E to the standard. In addition, the management of the data exchange process in general and adaptation in particular require the organization of the exchange of service messages between nodes. Such messages are provided in the exchange structure and are described in detail in C to the standard.

The applied level of the functional structure is the highest level in relation to the others that provide him with data transportation services. Client types are defined in such a way as to enable the development of an initial set of applications that use a radio subnet to communicate with each other.

Table 1 shows the standard subnet access point identifiers (TAPs) for application clients.

The work of yours. The minimum requirements for managing the local node are fulfilled using the primitives C_ request _upr message_prd C_indicat_upr message_prd C_availability of subnet, etc.

The primitive has an MSG message as an argument. The primitive is generated by the client in order to transmit a control message addressed to the subnet. The meaning and structure of the MSG argument is implementation dependent and is not defined in the standard. The subnet accepts this primitive only from clients that have rank 15. Depending on the value of the combined argument, the MSG primitive can take the form of a command (for example, “radio silence” or “radiation”) or a request (for example, request statistics, request a list of connected clients, etc. .P.). This primitive is not intended for transmitting control or coordinating messages over the communication channel to other nodes. This is the prerogative of the process of interaction between managing clients of various nodes and is performed using the corresponding primitives S.

The primitive S _Management _ vsg_indication is generated by a subnet either in response to a client request or independently by a subnet, and also has a structured argument MSG, the interpretation of which is implementation-dependent and is not defined by the standard.

Primitive S is generated by the subnet interface layer and is intended for all or some of the connected clients. Its arguments are the status of the site and the reason code, and its purpose is to inform customers about changes in the status of the site. For example, using this primitive, clients can be informed about the temporary unavailability of subnet services due to reservation of a communication channel by a high-priority client. Another example would be informing clients about the introduction of a radio silence mode and, as a result, that they can only rely on receiving data in simplex modes.

The priority argument is the P-TIR priority value, which can be between 0-15. Lower-level message service protocols provide the ability to earlier service higher priority messages.

The TDP-Destination ID argument specifies the access point number of the destination host to which the message is intended. Since the numbering of access points is the same for all nodes, the argument ensures that the message is brought to the desired access point.

The argument “destination host address” defines the address of the physical node of the KB network to which the destination client is connected.

The argument "delivery method" is structured (composite) and has a number of attributes. The encoding method for this argument is illustrated in Table 2.

table 2 7 | 6 | 5 4 | 3 | 2 one 0 The procedure for bringing the package Not used Transmission method Delivery confirmation Minimum number of repetitions one

The transmission method has the following meanings:

0000 - the field is ignored and the default transmission method is used;

0001 - with the repetition of erroneous frames on request (ARQ);

0010 - not ARQ (broadcast);

0011 - other non - ARQ methods, etc.

Delivery confirmation takes the following values:

00 - without confirmation;

01 - confirmation at the node level;

10 - confirmation at the client level;

11 - not defined.

The procedure for bringing the package is as follows:

0 - sequentially in order;

1 - in the order of bringing.

The minimum number of repetitions is used only in the case of one-way transmission methods (non-ARQ). Otherwise, the field value is ignored.

The "delivery method" argument can be set to the "default" value, which is determined by the client during connection to the subnet.

The TJ argument (T life = life time) determines the maximum time the message spends on the network before it is delivered to the addressee. If this time is exceeded, the message is destroyed. If TJ = 0, then this is interpreted as an infinite lifetime.

The argument "TIR size" determines the volume of the data module issued to the network by this primitive. TIR is actually a message (data module).

Subnet management clients connect to the subnet in the DTP with ID = 0. The rank of the client, if he has the rights to form and issue commands that change the configuration of the host or subnet as a whole, should be 15.

To manage the subnet, applicable standards, such as the Simple Network Management Protocol (SNMP) or the common information management protocol CMIP, are used.

Delivery confirmation message.

The client / server application for the delivery of messages with delivery confirmation defines the application-level client-server protocol that supports message delivery via point-to-point radio channels with delivery confirmation according to the rules of the standard.

The client-server connection is defined with respect to the one who sends messages (client) and the one who receives them (server). Applications that support two-way communication between two nodes using an acknowledgment message delivery protocol must support both client and server functions.

Sending messages supports the transmission of text-based messages from the local user of one node to the local user of another without maintaining its forwarding function at the application level.

The messaging server is based on the basic mail transfer protocol (SMTP) defined in the Internet standard 10, RFC 821, modified in terms of grouping commands as defined in the RFC.

NMTP (Radio Mail Transfer Protocol) The client / server protocol of the application layer provides acknowledged delivery of SMTP email messages over the radio channels of the subnet. The service characteristics for the HTTP protocol are as follows:

- The basic mail transfer protocol in accordance with the Internet 10 and 11 standards (i.e. RFC 821 and 822), with service extensions;

- SMTP service expansion mechanisms in accordance with RFC 1869 and the stated additional modifications; etc.

Commands, replies, and message data related to NMTP are issued to the radio subnet using standard S primitives, which have the following service parameters by default:

- transmission method;

- delivery order;

- delivery confirmation, etc.

The address indicated in the primitive must be an individual node address corresponding to the address of the radio subnet or host on which the NMTP client or NMTP server is located.

Official exchange of operators.

For service acknowledgment messages, the procedures described for delivery confirmation messages apply. For messages without confirmation, service channel clients connect to the access point with ID-5.

Remote control of radio facilities 12 is performed automatically or manually with AWP 14. Control of channel-forming radio facilities involves turning the power on and off, changing the mode and type of work, setting the frequency, power and other parameters provided by a particular radio facility. The ability to control the radio means 12 is determined by the system protocol between the AKKP 11 and the shipborne transport network (VKTS).

Automatic switching between AKKP 11 and radio channels. Automatic switching of information and control circuits of radio facilities into the path is made by selecting the path structure according to the given ranges and type of communication from the path structure database. Switching of communication paths can be done by the duty of communication or by requests from subscribers.

Switching of information and control circuits of the TS is carried out in IMS 10, which also provides physical and logical connection with the TS according to the agreed protocols of interaction between switched TS.

The ship's corrective post provides data preparation and fire control for naval artillery of fire support ships, including:

- topographic and geodetic reference and orientation in an automated mode;

- determine the polar coordinates of the target and recalculate them into rectangular;

- Indication on the display of the AWP AKKP of the results of data processing and received messages;

- preparing data for transmission over radio channels;

- exchange of information in digital form and voice messages with the PUAO of the fire support ships of the CPC and the commander of the AKKP.

The ACCP tests were carried out on the radio route St. Petersburg - Kamaika in the HF band. When conducting checks on the exchange of information in PCNet mode, a steady speed of exchange of mail messages of 3200 bps was achieved, and the technical speed of information exchange was 9600 bps.

The use of the claimed complex allows you to expand the functionality by automating fire control of naval artillery fire support ships.
