Description

This utility model relates to the field of radio electronics, namely to the technique of transmitting analog and discrete information, and can be used to organize external and internal communications on ships, ships and other mobile objects.

Communication between complexes and systems for various purposes is carried out using cable routes laid on ships. Dozens of different-sized cable lines penetrate the waterproof bulkheads and decks of the ship, linking together electronic complexes and their elements; they cost 60% or more of the cost and complexity of installation and commissioning during the construction of ships.

The complexity of cable connections makes it difficult to upgrade ships. With the conversion, the cost value also increases.

It is unrealistic to reduce the amount of transmitted information in these complexes and systems, on the contrary, automation of control processes leads to a constant increase in the amount of transmitted information, but the main way of communication between electronic subsystems of external and internal communication can be simplified.

The well-known "System of intra-ship loud-speaking communication and broadcasting" (RF patent No. 3111168, class 6 N 04 B 13/00).

The system consists of switching centers (CC), connected in series by fiber-optic communication lines to which switches, panels and other units are connected, while the CC contains N subscriber modules connected to the main and backup control and information buses.

This system allows you to expand the functionality of the equipment and increase the efficiency of using the intra-ship communication network (VKS) by combining several types of services (transmission of loud-speaking communication and broadcasting, transmission of control signals).

However, this system has significant disadvantages:

- the impossibility of allocating a certain part of temporary positions (communication channels) for transmitting broadband signals;

- low system bandwidth (about 8 Mbit / s per line), which does not allow combining the external communication complex into a single system;

- switching of signals of various terminal devices included in the CC is not provided;

- low transmission speed in the subscriber channel;

- the use in the system of pulse-code modulation (PCM), and hence sophisticated equipment, in particular a signal converter at each end point, which significantly increases its cost.

Closest to the claimed system according to the technical essence of solving the problem is the "Automated Integrated Digital Communications System" (RF patent No. 2188511 from 02.25.2000, CL 7 H 04 B 13/00). The system contains a central switching unit (PPM) and N switching units (BC), to which information sources and subscribers are connected. PPM and BC are interconnected via fiber-optic communication lines.

The system provides all types of videoconferencing, management of automated communication systems (ACS) and switching information paths of the ACS.

The disadvantages of the prototype are the dependence of the quality of information transfer on the length of the subscriber lines, large hardware and cable redundancy, low reliability and survivability of the system, because the failure of only one pulp and paper mill incapacitates the entire system.

The purpose of the utility model is to expand the functionality, increase reliability and survivability, while reducing the cable network.

This goal is achieved in that the complex structure is made in the form of h-1 connected rings, where h is the number of premises of the object in which CCs are installed, each of which is connected to all other CCs through fiber-optic communication lines, while CCs contain serially connected a microprocessor, a sound card, a modem unit of a radio base station, a modem and sound card control unit, N AU control units, N subscriber module boards and N E1 interface boards connected by a transceiver line to an information storage device, The AU volume contains a switch for electro-acoustic devices and lines, a microcontroller, as well as direct call buttons, a display and a dialer, which are parallel connected to the microcontroller, and the AU control units and the modem and sound card control unit are connected to the AU microcontroller at the RS-485 interface, and subscriber module boards are connected via the physical subscriber line to the main and spare subscriber lines of the switch of electro-acoustic devices and AU lines, while the interface cards have four outputs of type E1, the sound card the uk card is connected to the broadcast source, and the modem unit of the base radio station has N FSM type outputs, and the microprocessor has two Ethernet connectors, two RS-232 ports and a USB interface, and the switch of electro-acoustic devices and AU lines is connected to the broadcast line and has inputs and outputs for electro-acoustic transducers.

The block diagram of the control system of the ship communications complex is shown in Fig.1. It contains: switching centers (CC) 1, each of which is connected to all other centers of fiber-optic communication lines (FOCL) 2. Each subscriber 1 is connected to

devices 3, and electro-acoustic transducers are connected to subscriber devices 3 (not shown in FIG.).

The structural diagram of KC 1 is shown in figure 2. It contains: a processor 4, a sound card 5, a modem unit of a radio base station 6, a control unit for a modem and a sound card 7, control units AU 8, cards for subscriber sets 9, interface cards of type Е1 10 and information storage devices 11.

Figure 3 shows the structural diagram of the AU, it includes: a switch of electro-acoustic devices and lines 12, providing control of the connection of electro-acoustic devices (microphones, headsets, speakers, etc.) that are active in the current operating configuration of the AU, as well as provides software-controlled switching from the KC 1 subscriber line status (primary, backup); microcontroller 13, display 14, dialer 15, direct call buttons 16, which are used to select a subscriber in the process of establishing two-way telephone communication between subscribers equipped with AU.

AU is connected to CC 1 with a two-wire subscriber line, which provides reception and transmission of voice information in all operating modes, and a control line with an RS-485 interface, through which control and interaction signals are exchanged between AU and CC 1.

The basis of the block diagram shown in figure 1, is a subsystem of transport communications, implemented by means of KC 1 and communication lines between them. On its basis (using its resource) there are five subsystems that provide services to subscribers and the work of other subsystems of the complex:

- speakerphone subsystem (GHS);

- telephone communication subsystem;

- translation subsystem;

- data transmission subsystem;

- a subsystem for interfacing with external exchanges.

The functional structure of the complex includes subsystems of power supply and technical operation as devices that ensure its operation (not shown in Fig.).

The operation of the shipboard communications control system is as follows.

The intrabuilder communication network is a distributed switching network of digital communication channels with a bandwidth of 64 kbit / s each. As switching equipment, KC 1 located in the compartments of the ship is used. The connection between them is organized on the basis of PCM channels of the “E1” primary path with a group speed of 2048 kbit / s. In KC 1, user equipment is included, which in the complex is represented mainly by AU and telephone sets (TA).

According to the information specified from the AU, the following types of videoconferencing are provided in the intra-ship communication network:

- two-way telephone communication;

- a direct call between the AU of the ship's posts in the GHS mode;

- circular call;

- group duplex conference communication, etc.

When a communication path of a certain type is formed with the TA and AU of the initiator of this communication, the following information is transmitted:

- a sign of the type of connection;

- user category;

- number of the called subscriber;

- Caller’s own number (it is determined in CC 1 by identifying the TA and AU switching lines in CC 1).

In the case of initiating a connection from the TA, the sign of the type of connection and its category in CC 1 are determined by the correspondence of the subscriber line to the telephone. The specified information on the AU-KC 1 site is transmitted in RS-485 interface modes.

Based on the received information, the software of KTs 1 implements the processes (algorithms) of signal exchange between KTs 1, selects the optimal path to establish a connection (i.e., switches paths as the final phases of the connection are used positively) and checks the connected path for integrity and answers the subscriber's call .

The signal exchange between the CC 1 is carried out by transmitting the “3 out of 8” code combinations in the signaling channel allocated in the E1 channel (16th channel) in accordance with the adopted algorithm.

The channel signaling system of the videoconferencing network ensures the establishment of all types of videoconferencing, as well as the notification of CC 1 about the status of the E1 group paths included in each of them, which is the basis for the dynamic control of the routing of connections in the network.

Based on the information of the dynamic control of the KC 1 program, automatic traversal of damaged network sections is provided and communication is established through operable KC 1 and connecting lines 2 between them.

The connection establishment format (FCS) essentially represents the initial address message that is used in the formation of paths of all types of communication.

The type of communication that should be implemented in the network on the basis of FUS is determined by the type of signal occupation.

The FSF signal bytes are transmitted from one KTs 1 to another via a dedicated signaling channel in the manner of an intervalless packet. With the intervalless transmission method, two identical combinations next to each other can merge into one signal. To avoid this, when transmitting signals, the next identical combination is replaced with a “Repeat” signal (SU 11 signal). At the receiving end, the signals are reversed.

Improving the reliability of the transmitted signal information is ensured by applying algorithmic procedures for confirming each signal (packet) of the forward direction with the corresponding reverse direction signal.

Integration of the control system of the complex consists in the transition from the use of numerous direct connections between the AUs according to the “button-communication” principle to a fully accessible highly reliable switched system that provides the specified characteristics of automatic connection. The joint use by all subsystems of the resource complex of the subsystem of transport communications, built on the basis of CC 1 and communication lines in the form of h-1 connected rings, solve the problems of optimizing the values of their throughput. The failure of any of the CC 1 or any of the lines does not violate the connectivity of the structure when the AU is connected to two CC 1, the violation of the structure will not lead to the loss of any communication between subscribers.

Using the inventive ship complex management system allows you to expand the functionality of the equipment due to additional radio communications, video conferencing, data transmission, as well as to ensure the efficient use of a transport network that combines all subsystems of intra-ship communications, while significantly increasing the reliability and survivability of the VKS complex.
