Description

The invention relates to the field of electrical and radio engineering, in particular, to the technique of transmitting analog and digital information and can be used to organize on-site digital loud-speaking, telephone, video communication and broadcasting on stationary and mobile objects, including land-based and sea-based objects.

A well-known system of in-ship speakerphone and broadcast. (Patent of the Russian Federation No. 2131168 from 05.29.1996, class. Н04В 13/00). The system is designed for the organization of in-ship voice and telephone communications. This system is designed for the use of switching centers (CC), which are serially interconnected by digital channels of E1 standard (2.048 Mbit / s) using fiber-optic communication lines (FOL), and they are connected to switches and consoles, blocks of cabin and cut-off loudspeakers and other lines.

Known Automated system of integrated digital communications. (Patent of the Russian Federation No. 2188511 of February 25, 2000, class NV04 13/00). The system consists of a central switching unit (PPM) and switching units (BC) to which information sources and subscribers are connected. The PPM and BC are interconnected by digital channels of the E1 standard (2.048 Mbit / s) using fiber-optic communication lines (FOL).

Known Unified complex intraclass communication. (The patent of the Russian Federation for No. 2261530 from 12.05.2003, cl. НВВ 13/00). The complex contains integrated switching centers (ICCs), each of which is connected to all other centers by digital channels of the Е1 standard (2.048 Mbit / s) using fiber-optic communication lines (FOCL). Analog subscriber units (AU) are connected to each ICC, and electro-acoustic transducers are connected to the AU.

Known Multifunctional system intracoupler communication. (Patent of the Russian Federation No. 2304349 dated July 08, 2005, class NV04 13/00). The system consists of a central switching unit (BCC) and switching centers (CC) interconnected by digital channels of E1 standard (2.048 Mbit / s) using fiber-optic communication lines (FOCL), terminal equipment (data transmission equipment, facsimile, telephone and telegraph, operator console).

The disadvantages of these analogs are that their switching system is based on the use of digital circuit-switched technology and analog terminals are connected to this digital switching system, which causes low network bandwidth, lack of reliability and limited functionality.

The closest analogue, chosen as a prototype, is the Ship digital loud-speaking communication and alert system. (Patent of the Russian Federation No. 2492583 dated 07/19/2011, class N04M 9/08). The system consists of a digital integrated service network (ISDN), to which subscriber devices, cabin and cutoff loudspeaker blocks, an automatic telephone exchange, digital and analog telephone sets, an analog interface module, to which a radio base station is connected, are connected. The establishment of connections in the system is carried out by IP-switching.

The disadvantage of the prototype is that the ISDN uses digital channel switching technology (2B + D, 30B + D channels), which requires interface converters for connecting subscriber terminals using IP switching technology, which introduces additional time delays An automatic telephone exchange is required for the communication system; the system does not provide video communication between subscribers and wireless subscriber access.
