Description

The invention relates to communication technology and can be used to transmit information in rail transport.

A known radio communication system of the GSM-R standard, comprising base stations connected to base station controllers (BSC), which, in turn, are connected to a mobile switching center (MSC), to which an intercom and call device is connected via an automatic telephone exchange control) dispatcher.

The system provides a mutual call and negotiations between the dispatcher and train locomotive drivers to control the movement of trains.

Establishing connections between the dispatcher and the locomotive driver in the system is carried out by dialing on the dispatcher’s console (when connecting to it) or on the driver’s console (when connecting to the dispatcher) a known locomotive radio number or a known dispatcher’s number. The system is published in the document of the International Union of Railways: “UIC Project (UIC) EIRENE. Specification of system requirements. Part II ”, publication date October 21, 2003, pp. 25-30, p. 1.4.

A disadvantage of the known system is the need to dial a locomotive station without indications of its location in the control room.

A known mobile communication system, in particular, for use in rail transport in the GSM-R system, which uses an architecture that supports the use of functional numbers for addressing purposes in wireless communication networks, and a method for transmitting functional numbers between the respective devices included in this architecture.

The system includes an access matrix located in a Service Control Point (SCP) connected to a local mobile subscriber register (HLR) and to a GMSC mobile switching center connected to railway switching centers (MSC) )

The invention also provides a flexible and expandable coding scheme for additional service operations used to register, request and deregister functional numbers in the GSM-R system.

The use of functional numbers registered in the zones of the respective base stations to establish connections is implied by dialing the corresponding number on the dispatcher's control panel. The system assumes the use of a typical dispatcher control panel, calling subscribers from which it is dialed (EP 1860893 H04R 7/22, publ. 28.11.07).

The disadvantages of the system are the lack of visual information about the numbers of trains (locomotives) located in the dispatch area, and the need to dial a number to establish a connection between the dispatcher and the locomotive driver.

The technical result of the invention is to increase the efficiency of establishing connections in a mobile communication system in rail transport.

The technical result is achieved by the fact that in a mobile communication system in railway transport, containing base stations at each station of the dispatch section, connected by a primary digital channel E1 to a base station controller connected via a transcoder to a mobile switching center that is connected to a service support service node, with a position register, with a movement register, with a functional addressing register and with an El / Ethernet gateway that is connected to a packet-switched network of the dispatch system, the base stations through radio channels are connected to locomotive radio stations, according to the invention, a dispatch system server, a switch and a dispatcher control panel consisting of a personal computer with a touch monitor and an intercom are introduced, while the dispatch system server is connected to a packet-switched network of the dispatch system to which a personal computer with a touchmonitor and an intercom for the dispatcher’s control panel are connected through the switch, and the sys topics connected are the service support service node, functional addressing register, movement register, and position register.

The drawing shows a structural diagram of a mobile communication system in rail transport.

The railway mobile communication system comprises base stations 13 at each station of the control section connected by a primary digital channel E1 to a base station controller 12 connected via a transcoder 15 to a mobile switching center 11, which is connected to a service support unit 8, with a register 9 positions, with the movement register 10, with the functional addressing register 7 and with the gateway 14 E1 / Ethernet, which is connected to the network 5 with the packet switching of the dispatch system, base stations 13 through radio channels the ides are connected to locomotive radios 6, the dispatch system server 3 is connected to the dispatch system packet network 5, to which a personal computer 1 with a touch monitor and intercom 2 of the dispatcher control panel are connected through switch 4, the service node 8 is connected to the dispatch system server services, register 7 functional addressing, register 10 movement and register 9 position.

The mobile communication system in railway transport operates as follows.

For the regular functioning of the system, current information on the functional addresses of locomotive radio stations 6 is used, combining the train number and the number of the radio station that established communication with a specific base station 13 (registration of locomotive radio station 6 in the corresponding cell), which arrives at the switching center 11 of the mobile communication. The switching center 11 of the mobile communication provides switching of the radio channels during the movement of the locomotive, ensuring continuity of communication (HANDOVER) as the locomotive station 6 moves from the communication zone of one base station 13 to the communication zone of another. Information about the functional numbers of locomotives registered at a particular base station 13 and deregistered as the locomotive moves, is concentrated in the position register 9 (HLR) and movement register 10 (VLP) used in the system, paired with the mobile switching center 11 (MSC) . Information about the functional addresses of the moving objects is concentrated in the register 7 functional addressing (FAR). Registration of locomotive radio stations 6 is provided as a result of periodic transmission from them of information about the functional number in the form of short messages (SMS). As a result of the receipt in the position register 9 and the movement register 10 of the above information necessary for establishing address communication, it becomes possible to obtain a graphic display on the screen of the control panel of the train locomotive dispatcher with the indicated numbers of trains (locomotives) located at each moment in the zone communication of the corresponding base station 13 in the control area. The dispatcher's control panel is built on the basis of a personal computer with a touch monitor (made using Touch-Screen technology) using a separate screen form (page) for each type of communication. On-screen forms of the corresponding types of communication are depicted in the form of button information and control panels with the designated names of subscribers (objects). On each page there is a window with constant information for all types of communications organized using the remote control for the corresponding workstation. In particular, for the dispatcher's console, a screen form for organizing train radio communications and communication with the foreman of passenger trains should be formed. On each page there should be a window with all the function keys necessary for this type of communication (sending ringing signals, setting the subscriber to standby, hang up, etc.).

When the locomotive leaves the zone of interaction of one base station in the zone of another, the image of the locomotive disappears in the zone of the previous base station and appears in the zone of another base station through which communication is established. To establish a connection with the locomotive driver, the dispatcher must touch the display of the locomotive on the monitor screen with the corresponding train number. With an incoming connection, a call from the locomotive driver is indicated on the monitor screen by a color change and the locomotive display flashes on the monitor screen. To establish a connection, the dispatcher just needs to touch the display of the calling locomotive on the monitor screen.

The information necessary for this purpose is removed from the standard registers 9 of the position and 10 movements associated with the switching center 11 of the mobile communication, and is transmitted to the server 3 of the dispatch system, which, in turn, is connected to the local network 5 with packet switching of the dispatch system. The server 3 of the dispatch system is also connected to the functional addressing register (FAR) 7, which contains a database of functional numbers of mobile and stationary objects, and to a service support service node 8 (SGSN). Call and conversation signals between the control panel of the dispatcher (station duty) and the locomotive radio station 6 are transmitted via a separate circuit connecting the IP network of the dispatch system to the switching center 11 of the mobile communication via the E1 / Ethernet gateway 14. To the network 5 with the packet switching of the dispatch system are also connected control panels of station attendants (not shown).

Locomotive radio station 6 transmits periodically automatically SMS short messages containing a functional number combining the train number and the radio station number.

When establishing a connection of the locomotive radio station 6 with the switching center 11 of the mobile communication through one of the base stations 13, information about the functional number of the locomotive radio station 6 and the identification number of the base station 13 through which the connection is established, is transmitted through the switching center 11 of the mobile communication to position register 9, register 10 movement and register 7 functional addressing, which, in turn, after appropriate processing, transmit the specified information to the server 3 of the dispatch system associated with the service node 8 support services, from which the server 3 receives information about the identifier of the base station.

A correspondence table between the identifiers of the base stations and the functional numbers of the locomotives is created in the server 3 of the dispatching system, according to which locomotives with train numbers in the zones of the respective base stations are displayed on the screen of the monitor of the personal computer 1. The server 3 of the dispatch system also provides a correspondence between the locomotive number displayed on the monitor screen and the communication channel with the locomotive radio station 6.

When establishing an outgoing connection, the dispatcher touches the image of the locomotive on the touch monitor of personal computer 1 with a specific train number. In this case, the server 3 generates a corresponding ringing signal arriving at the locomotive radio station 6.

After the response of the driver, the negotiations between the dispatcher and the driver are carried out along the line connecting the switching center 11 of the mobile communication through the gateway 14 to the network 5 with packet switching of the dispatch system.

An incoming connection from the locomotive radio station 6 to the dispatcher's control panel is done by sending the dispatcher's functional number, as a result of which the image of the locomotive from the radio station 6 of which the call was received on the monitor of the personal computer 1 is indicated by a flashing light signal on the monitor.

Negotiations between the dispatcher and the driver are also carried out on the line connecting the switching center 11 of the mobile communication through the gateway 14 with the network 5 of the dispatch system.
