Description

The railway radio dispatch system is used for the transmission of speech and commands between the rail vehicle and the radio dispatch center. The system
consists of a dispatch center, fixed railway radio base stations deployed along the rail, a modulation line, and mobile radio stations located in rail vehicles.

In the existing analog system, the connection between the dispatch center and the fixed radio stations is wired, while the connection between the fixed and mobile radio stations is wireless, realized by radio waves. The modulation line can be with optical fiber or may be a four-wire connection, where one pair is used to send information in the direction from the dispatch center to the rail vehicles, while the other pair is used to send information in the direction from the rail vehicle to the dispatch center.
The digital radio dispatch center (D-RDC) is designed to be fully compatible with the existing analog dispatch center by supporting all currently used services with the possibility to easily add new ones. This enables easy replacement of existing analog dispatch center with the new D-RDC systems, without any modifications done on modulation lines, fixed railway radio stations, and mobile radio stations in rail vehicles.

The entire manipulation of the D-RDC system is performed through the dispatch control panel. The control panel allows you to view the history of sent commands, and the history of received notifications, to send commands to the rail vehicle, to receive notifications from the rail vehicle, initiate calls to the rail vehicle, and receive calls from the rail vehicle, as well as to test fixed radio base stations.
Basic functions of the system:
o Inbound and outbound voice calls
o Sending commands and receiving notications
o Testing of xed radio stations
• All sent commands and received notications are stored in system database
• All inbound and outbound calls are recorded and stored in systems storage
• System can be connected with various external systems (e.g. PSTN, private PBX)
• Easy replacement of an old analog radio dispatch central station
• Compatible with UIC 751-3 standard
• System is adaptable to dierent markets and rulebooks
• Supports operation along optical ber modulation line
• Operational voltage: 230VAC
• System autonomy is designed according to user requirements (up to several hours)
