The disadvantage of this device technology radio is the lack of integration of new and existing radio systems to meet the requirements of technological processes for managing the movement of trains and steady radio all subscribers train radio communication - train traffic controllers on duty at the stations, engineers and other Current practice of digital radio systems on the Railways shows that the construction of infrastructure systems, GSM-R and equipment rolling stock assigned to the locomotive and railcar depot, located on specific sections of Railways, can be completed within 2-3 years. However, localized areas are not isolated, they can contact the rolling stock is not equipped with a radio system GSM-R. in Addition, part of the control plots may have otwell the tion, you do not plan to equip new digital radio communication systems.

The essence of the proposed system consists of a set of key characteristics, sufficient to achieve provided the proposed system technical result.

Thus, the proposed technical solution meets the conditions of patentability of an invention.

Other known technical solutions for a similar purpose with such essential attributes not found.

The drawing shows the proposed integrated network of technological radio communication rail transport.

Integrated network technology radio communications rail transport includes a mobile station 1, panels 2 manage managers, a base station 3 connected in a "star" or "ring" or a mixed scheme(combined), connected in series, the switching unit 4, the transcoder 5 and the controller 6 base stations, the outputs of which are connected with the passages of the base stations 3, connected in series 7 business and home 8 registers location, a second input connected to the output unit 9 identification equipment, and first and second outputs connected to first inputs, respectively, of a business register location 7 and the switching unit 4, a second input connected to the output of the computing device 10 workstation operator radio entered the panels 11 of the control duty at the station, each of which is connected with the corresponding primary multiplexer 12, which are connected in a ring and through the first gateway 13 El/Ethernet LAN data transfer, which is connected with the server 14 location of stations with remote 2 control managers, with fixed stations 15, with digital interfaces with a third input of the switching unit 4 through the second gateway 16 El/Ethernet, and through the third gateway 17 El/Ethernet with the management station 18 operational process communications, to which is connected the Executive station 19 operational process communications, each of which is connected to the stationary radio station 20 with analog interface connected to the block 21 meeting of the devices of the duty station. Remote 2 control managers made in the form of serially connected unit 22 register of the addresses of all the Stazione what situations radio stations block 23 registration address of the mobile radio unit 24 of the negotiating device. The remote control 11 control of the duty station is made in the form of series-connected unit 25 registration address of the nearest stationary radio unit 26 registration of addresses of mobile stations and a block 27 of the negotiating device.

System integrated digital-to-analogue train radio communication works as follows.

Linear channels-Board digital-to-analog radio and common channel signaling (ACS) operational process communications received from the administrative station 18 OTS interface E1 through the gateway 17 El/Ethernet LAN packet-switched IP-connected consoles, 2 controllers, proxy server, the output switching unit 4 for mobile communications (MSC) of the GSM-R and through the gateway 16 El/Ethernet channel primary multiplexers 12, is used to connect panels 11 duty stations for GSM-R network Obts and RMTS.

Information and logical interaction connected to the LAN IP of objects with 2 consoles Manager and duty stations 11 is SIP.

When such integration are provided with all necessary relations managers and duty stations in systems GSM-R and digital to analogue train radio.

Given the modern tendency with the Denmark negotiation-dialling and control devices on the basis of computer technology, the integration of the digital-to-analog radio system and radio communication standard GSM-R on the negotiation-calling the remote controller 2, it is expedient to carry out when building console-based computer with monitor technology Touch-Screen to use for each type of communication separate screen form (page). Screen form appropriate means of communication should be represented in the form of a keypad and control panel marked with the names of the subscribers (objects).

On each page must be provided by the window with a constant for the relevant workplace information about all types of communications organized by using the remote 2.

For example, for remote 2 train dispatcher must be formed, as a minimum, the following screen form:

- train radio communication system GSM-R;

- train radio communication in the digital-to-analog system;

communication with the leaders of the repair units;

- communication with subscribers Obts.

On each page there should also be a box with all necessary for this type of communication function keys (send call signals, placing a caller on hold, hang up and others).

To enable a specific type of communication is performed by briefly touching the corresponding key, which in this case is colored in a specific color (e.g. the, green)to signal the user about the included status information and control panel of the desired form of communication.

The call to establish the appropriate connection, disconnection and other functions are performed by touching the appropriate keys of the information-control field and office Windows of this type of communication.

Switching to another type of communication is performed by the user touching another key official open forms of communication.

At the same time on the monitor goes blank previous page and included a new, corresponding to the button pressed.

When call from a caller (object)on closed at the moment the page, key in this type of communication in window service information types of communication light in flashing mode accompanied by an acoustic signal.

In this case, to connect to the caller, the user must click on this key and then the key that displays the caller.

Switch to the page on which you received the call, possibly as a violation of the connections established on the previous page, and save them back to the interrupted negotiations.

The remote supplied with the intercom 24 containing a micro-telephone headset with PTT switch, loudspeaker manual reg is the system volume and rendered electret microphone.

Hardware-software complex based on system GSM-R, enables the creation of computer consoles, highly ergonomic indicators, providing the opportunity for rapid connection to the desired subscriber (object), which is especially important in emergency and disaster situations.

Provided in the system GSM-R registration of mobile users that communicate with the corresponding base station 3, with the transfer of the conditional number of the subscriber and the number of the base station 3 in the switching unit 4 mobile, which is associated with the panels 2 managers and duty stations 11, gives the possibility of obtaining a graphical image on a display form of remote train locomotive with the indicated numbers of trains in the areas of specific base stations.

When moving a movable object (locomotive) in the area of communication with another base station 3 picture locomotive disappears in the area of the previous base station and appears in the zone of the base station 3, through which a connection is established.

Besides the machinists train locomotive, the Manager has the ability to call the brigade trains and transfer by train loudspeaker network communication to the passengers.

Similar units can be provided to the power dispatcher and locomotive Manager.

When the computer consoles on the display of each Manager displays involved in negotiations with other managers moving objects.

On the remote control 2 Manager may provide input to the GSM network to communicate with the drivers of locomotives. For this purpose must be formed corresponding page (display form), and to the network IP host integration must be connected to the gateway 16 GSM.

Possible organization and other villages (screen forms) for output Manager in the network of green links, information on the movement of mobile objects, etc.

For the implementation of the function "Emergency stop trains" should be a separate screen form.

Connection panels 11 duty station to the switching unit 4 mobile through which you are connecting their base stations 3 and finally, the remote locomotive engineers by using primary multiplexers 12, interconnected by ring-diagram of the primary digital channels (E1).

To enable automatic switching to the bypass tract rings in the primary multiplexer 12 includes the following:

channel In each panel 11 is connected to each multiplexer 12 to the corresponding channel BCC via the digital adder that enables the console works in both directions;

for signaling information and logical interaction of the remote control unit 4 switching mobile when working on the main or bypass napravleniya used is included in the multiplexer dispenser, for the transmission of signals in both directions for two channel intervals;

- to avoid self-excitation in a ring circuit channels BCC mainstream communication is disconnected in one of the multiplexers 12 (prescribed, usually in the centre of the railway Department) with channels forming the bypass tract rings. Aggregation of the primary and bypass the disruption in the main direction of the ring is included in the multiplexer 12 of the control signal to the device that the transfer of relevant information in the system of MCA and ECMA;

- pair of primary multiplexer 12 to the local IP network by using the external or included in the multiplexer gateway 13 pairing El/Ethernet 10/100;

- pair of panel 11 of the duty station with the primary multiplexer provides primary access BRI (2B+D) interface So or Uko with the Protocol of the manufacturer of the console.

as of communications Protocol on the D channel in a linear path can be used a standard Protocol LAP-D.

When using computer technology panel 11 of the duty station should be constructed similarly to the 2 remote Manager.

Possible use in the duty station simpler remote, represents the future of a digital telephone device, containing key group call drivers of locomotives, a keypad for dialing the called locomotive when an individual calls and other function keys and indicators.

Talks of the duty station with train locomotive engine drivers in network digital-to-analogue train radio in this embodiment is carried out via the standard remote particleboard, connected directly to the analog radio.

This option communication assistant station is the most reliable, because the disruption in one of the networks remains in effect another.

However, the use of computer remote control with on-screen form, showing the presence of specific trains and repair of units registered on the base transceivers and its neighbouring railway stations, significantly increases the efficiency of communication of the duty station with the engine-drivers, which has a positive effect on ensuring traffic safety.

Additionally, the display on the computer screen employment the driver of a particular locomotive negotiations with the Manager directs the assistant station in compliance with the relevant regulations of the negotiations.

To establish a strict sequence of negotiations Manager and assistant station with a specific driver to turn the key it is impossible, especially in emergency situations. For harmonizing the actions of the Manager and assistant station in these cases should be used in train dispatching calls.

Possible construction of computer remote duty station with the formation in addition to the screen form of communication with the drivers of train locomotives in GSM-R, also the screen that displays the link to the drivers train locomotive in the analog-to-digital train radio network.

In this case, the interface to connect the controller 21 DSP fixed stations must be connected through an appropriate gateway to the local station IP network, to which must also be connected to remote computer 11 DSP GSM-R and the input of the linear set of primary multiplexer 12. This option may be appropriate if the station's local IP network connection.

Must be organized train radio communication between the driver of a train locomotive, railcar trains, special self-propelled rolling stock and train dispatcher, duty stations, depots and travel; machinists counter and after running trains, other subscribers, equipped with portable and transportable radio.

It is also advisable to provide communication such subscribers as:

- energy - the locomotive Manager;

- Manager of the situational center;

control unit repair services.

As a subscriber devices stationary subscribers should be used:

- specialized control panels that are included in the monitoring system and connected by communication channels (wired remote);

- stationary subscriber radio stations with specialized remote control (transmitter). To ensure the required reliability of the system while optimizing subscriber load, it is advisable to subscribers of different categories to provide depending on the functions they perform different types of subscriber devices. Subscribers, perform the most important functions of motion control, such as a train, energy and locomotive managers, duty stations and some of the other categories should be equipped with control panels, plug-in specially organized wired channels to the control system. The rest of landline subscribers may be given by the so-called radiopurity representing a subscriber station with a dedicated remote control.

When designing a digital radio system GSM-R should be considered for equipment of subscribers of different types of radiograms is in:

control apparatus and duty stations can use wearable radio (PH) when outside premises; it is possible to use the call divert from the control panels on these radios;

- drivers can use wearable radio stations at the exit from the cab or finding outside the locomotive cab (remote control outside the cabin is in the off state and can only be used for negotiations between cabins);

- the head of the train can use wearable radio when moving inside the trains, on platforms, on-site stations.

For the organization of data transmission channels between subscribers and devices for GSM-R should be used in two modes:

- short message mode;

- mode transmission circuit switched data channels.

SMS mode assumes that the content of these messages are pre-recorded in the software radio or remote control (control room system). Initiative short message can belong to the subscriber Manager, duty officer at the station, the driver. The most popular may be the command "Stop the train", which should be formed by means of the remote control center and control room systems. Usage the use of this mode is likely to be in demand in the period up to the full equipping of the area traffic control system using radio. Upon entering the locomotive radio station this command should trigger the braking devices on the locomotive (that is, when the development of the locomotive radios are designed to work in an integrated system must be capable of pairing it with the device control movement of the locomotive).

A positive result from the proposed technical solution is that when using the integrated digital-to-analogue train radio communication is provided by the integration of new and existing radio systems to meet the requirements of technological processes for managing the movement of trains and steady radio all subscribers train radio communication - train traffic controllers on duty at the stations, engineers and others, the implementation of the new integrated system, and also provides effective management of the communication network and the creation of a modern system of its operation.
