In addition, at the station 8 there are installed communication devices 39 for meeting communications connected to the station IP network 3 of station 8.

An integrated system of technological communication operates as follows.

When establishing connections for negotiations in a dispatch system, dispatch and call control panels 30 are used, connected through a station IP network 2 ДДЦУ 5, transport IP network 1, station IP network 3 of the corresponding station 6-10 with call and call consoles 17 or 22 on duty by station or other managers.

The establishment of connections and negotiations in the system of station communication is carried out between subscribers equipped with remote controls 17 or 22, telephones 18 or 23 within stations 6, 7, 8, 9 or 10.

When organizing meetings, connections are established through the telecommunication server 12 or 13 between the intercoms 17, 22, 31 and 39 installed in the studios or workplaces of the respective managers.

Two-way station-based park communication and the transmission of loud-speaking commands are organized within each station 6-10 by establishing connections of the control panels of the managers 17 or 22 with the inputs of the translation amplifiers 19 and 24 loaded on the feeder lines 20 and 25, equipped with devices for reproducing sound signals (loudspeakers).

The leaders are called and negotiated with the process executives located in the parks using park intercoms (not shown in the drawing) connected to the CCGT lines 26 connected to the call-control panels of the managers 22 and 17 at the corresponding stations 6-10.

Informing passengers and alerting workers on the station's railway tracks of the approaching rolling stock is carried out according to commands received from electrical centralization systems 29 or centralization control rooms to a telecommunication server 12 or 13.

Based on the information received, the server 12 or 13 determines the feeder line in the park of the railway station or in the area of the passenger platform, along which a message about the approach of the rolling stock should be transmitted, and generates a speech message from the fragments in its database arriving at the input of the broadcast amplifier 19 or 24 and reproduced by the loudspeakers of the feeder line 20 or 25. Visual information is reproduced on the information board 14.

Monitoring the operation of passenger information systems about the arrival, departure, train route and the approach of rolling stock to passenger platforms is carried out using the automated workstation of the dispatcher of the warning system ARM-D 34 connected via station IP network 2 to the central information server 36. Dispatcher with the help of ARM-D 34, it is possible, if necessary, to cancel and enter a new message to the input of the broadcast amplifier 19 or 24 and to any information board 14 station 6-10 or stop point 11.

Passenger emergency messages are transmitted using emergency call columns 15 connected via station IP network 3 and transport IP network 1 to AWP-D 34 of the public address system dispatcher.

Distillation communication is carried out between the subscriber on the stage, using a portable or stationary intercom (not shown), connected to the ASG physical line 27, and on-duty at the station, using the intercom unit 22 or 17. In this case, the telecommunication server 12 or 13.

The proposed system also provides for the subscriber’s communication on the stage with the dispatcher, established between a portable or stationary distillation intercom and the controller’s console 30.

Monitoring the status and configuration management of devices of the integrated digital communication system is carried out using monitoring and administration tools, which include AWP 33 SMA, which operates under the control of the central information server 36.

All connections in the system are carried out using telecommunication servers 12 and 13. In normal mode, server 12 provides services to subscribers (objects) of stations 6, 7 and stop point 11, and server 13 provides services to subscribers of stations 8-10.

If the server 12 fails, the service of the subscribers of stations 6, 7 and the stopping point 11 takes over the server 13, while maintaining the service of stations 8-10. Similarly, the server 12 in case of failure of the server 13 assumes the services of subscribers (objects) served by the server 13, while maintaining the service of its subscribers.

Thus, the proposed integrated technological communication system provides the performance of all types of communication functions based on a single hardware and software platform based on the use of packet switching technology using mutually redundant server equipment, which allows us to simplify communication equipment, increase its reliability and reduce material costs for technical service.
