Description

This utility model relates to the field of radio electronics, namely to the technology for controlling a ship's radio complex and can be used to organize external and internal communications on ships, ships and other mobile objects.

It is known "Device ship loud-speaking duplex communication" (AS USSR No. 568210, CL NO 4 M 9/08). The device contains an electronic switch, microphones, loudspeakers, transmit and receive amplifiers, a control pulse shaper, a low-pass filter, a modulator, a demodulator, and other elements that form the receiving and transmitting paths.

The disadvantages of the analogue are the low noise immunity of the switches, the dependence of the transmission quality on the length of the subscriber lines, the large hardware and cable redundancy, while the device provides only intra-ship communication.

The well-known "Automated communications system of the type" Buran "(A. Katanovich, NF Directors. Modern systems of intra-ship communications. SP6, Shipbuilding, 2001. p. 118).

An automated communication complex (ACS) of the Buran type is designed to control a ship's radio complex. The basis of the complex is a collective line (LCP), which consists of a set of message transceivers (PRMDS), interconnected by two sealed data channels (primary and backup), forming a unidirectional ring. The AKC incorporates an antenna-feeder device connected via an antenna switch and channel forming means to a path switch, which, in turn, is connected to a subscriber switch through information processing and distribution equipment, to which

terminal equipment, remote communication post and other equipment are connected. The choice of the data transmission channel in the ACS is carried out by the message switching device (ACS) included in the LCP. LKP subscribers exchange information with each other in the form of messages implemented by bit-by-bit serial code. Only two subscribers of the single-ring LCP-transmitting and receiving, monopolizing the communication line for the exchange period can simultaneously participate in the exchange of information.

The disadvantages of the prototype are the large power supply of the facility, a branched power network, high density of electrical and radio devices leads to high electromagnetic fields of wide spectral composition, which, acting on the electrical circuit of the communication system, create interferences that reduce speech intelligibility, while the ACS has low bandwidth, reliability, survivability and a number of other shortcomings.

The purpose of the utility model is to improve the quality of information transmission channels, reliability and survivability while expanding the functionality.

This goal is achieved due to the fact that the automated communication complex is made in the form of four modules interconnected by means of a digital switching and control system (SCCC), while the first module is an antenna-switching equipment that contains transmitting and receiving antennas of various ranges, connected to four antenna switches, which in turn are interconnected by two power supplies and a fan control unit. The second module is a radio channel means of radio communication, which contain radio transmitting and receiving devices of various ranges, connected to the first input through a splitter or directly to antenna switches, the second input to a digital switching and control system, and the third

entrance with noise generators. The third module is a control equipment (AU), which contains a communication on-duty terminal, a signaling and control device, and an alarm control system, and the signaling and control device of the first input is connected to radio channels, the second input to the alarm system, and the third input with an external communication station, with closed telephone equipment and with a connected terminal, which is connected to the documentation equipment with a first input, a second input to the SCSU and a third input with four connected terminals. The fourth module is a terminal and special equipment, which contains five communication terminals connected to the STSKU, telegraph, telephone and data transmission equipment, while the STSKU is connected to the external equipment of other ship systems and systems.

The structure of the SCSU includes a control and switching device and a switch of terminal equipment. STSKU has two control modes: local from the front panel of the device and remote - at the RS-232 interface.

The control device is based on a microcomputer and processes the control information received from external devices, and is also intended to generate control codes for external devices and internal UU units (switching fields, control devices, etc.)

The operation of the ACS equipment is as follows.

After transmitting voltage to all the blocks of the system, except the control microcomputer SCSKU 5, the blocks go into standby mode, and the microcomputer STSKU 5 starts processing the initial installation program, according to which

the initial state for operation of all blocks and nodes of the complex system is established, and for a time, interruption of computers from all interrupt sources, except communication channels, is prohibited.

After the work of the computer initial installation program, from STSKU 5 proceeds to processing a cyclic control program, according to which all nodes and blocks of the system, as well as all means of the radio complex, are sequentially monitored (i.e., periodic monitoring occurs). At this time, all interruptions to the computer from all other sources are allowed.

If a command is received on the computer of the SCCCU 5 from any console or device, the monitoring program is interrupted and control is transferred to the interrupt processing routine, which, having determined the source of the interrupt, transfers control to that routine that works with this interrupt source.

After the end of this subprogram, control is transferred to the interrupted control program. If there are several interrupts, the interrupt routine determines the order in which they are processed in accordance with the assigned priority.

To determine the source of interruption, each means of the automated complex, as well as the control unit, which is controlled by a computer, is assigned an address and for storing information about their status, the corresponding memory area of random access memory.

When the ACS is in automatic mode, the formation of communication paths is carried out as follows:

- DS at its terminal selects the structure of the formed path and enters the necessary communication parameters (frequency, type of work, etc.);

- the DS terminal transmits a package of commands containing the information about the settings of the radio channel communication and switching facilities to the SCSU;

- STSKU 5 produces tuning, switching and control of radio communication means and AK;

- upon completion of the setup and switching process, a message is displayed on the terminal of the DS terminal to complete the formation of the path.

In the process of forming the path, a malfunction of the radio channel communication device or AK can be detected. In this case, the corresponding message is displayed on the display of the terminal of the DS, and the DS makes a decision to replace the faulty means or to terminate the formation of the path.

After the formation of the path, the settings of the special equipment are entered and the functioning of the communication channel is monitored.

In the process of working with the TLG Slo or TLG SLZ radio communication path, the operator:

- enables and disables transmission mode (PRD);

- adjusts the tone and volume of the received signal;

- sets the bandwidth of the received signal.

Management of the data transmission paths is carried out automatically from OA.

The backup operation mode of the ACS operation control is used when the DS terminal fails or if its software fails.

In standby mode, all the same paths are formed as in automatic mode.

When forming the paths, the switching of communication means is carried out in the signaling and control device, and tuning is done from their front panels in the local control (MU) mode.

Management of the shipboard ACS is performed by the DS:

- in automatic mode from the terminal of the duty officer for communication, based on the computer "Baguette-41";

- in standby mode from the front panel of the control and switching device, which is part of the SCSKU;

- in emergency mode from an alarm and control device and front panels of RPU, RPDU and PCT.

The proposed ship ACS provides:

- radio communication with coastal command posts (CP), NK. Submarines, aircraft in the ranges of SDV, SV, KB and VHF;

- sonar communication with submarines and NK.

The shipboard ACS communicates via auditory, frequency and phase telegraph radio channels, one and two-way telephone radiocommunications, data, space communications, and provides switching and control of communication facilities using STSKU and channel shaping in automatic, standby and emergency modes.

Using the inventive complex allows you to expand the functionality of the equipment and improve the quality of information transmission channels, as well as the efficiency of using a network that unites all subsystems of the ship’s ACS.

The technical and economic efficiency of the complex gives the following values of indicators - V ₁ = 0.41 of the prototype and V ₂ = 0.82 of the claimed complex, due to the reduction of mass and size characteristics, increasing the degree of unification, automation and throughput, as well as by increasing quality of information transmission channels, reliability and survivability.
