Description

The invention relates to train radio communication systems and can be used for centralized dispatch control in rail transport.

A known train radio communication system comprising an administrative stationary radio station at a central dispatch control station connected through a wired channel of dispatch communication with stationary radio stations of intermediate stations of a section, each of said stationary radio stations being connected via analog radio channels of a frequency range of 2 MHz to locomotive on-board radio stations located with them in the zone of reliable radio communication ("Devices of railway automation, telemechanics and communication" under D.V. Chaliagin, p. 169). A disadvantage of the known system is the limited functionality with respect to control the transmission of messages, due to the analog modulation methods and the fact that between the drivers and the dispatcher voice communication is provided only in simplex mode.

The closest known control system for transmitting messages by train radio communication is the prototype adopted system for controlling the transmission of messages by train radio communication from the Transport system ("Devices of railway automation, telemechanics and communication" edited by D.V. Shalyagin, p.171), containing the automated workplace of the train dispatcher at the central control room, the personal computer of which is connected via a local digital communication interface to the stationary administrative a radio station, which is connected through a wired channel of dispatch communication to stationary radio stations of intermediate stations, each of the stationary radio stations through digital radio channels (in this case, the frequency range of 330 MHz) is connected to the on-board radio stations of locomotives located in the stable radio communication zone, and the on-board radio station on the locomotive through the on-board digital communication interface is connected to the on-board control device of the locomotive.

The known system has enhanced functionality due to the duplex communication mode between the drivers and the dispatcher and the ability to transmit digital encoded information messages. The disadvantage of the system is that responsible voice messages from drivers to the train dispatcher (for example, messages about the place of an emergency stop of the train) are arbitrary, and group messages are brought to the attention of an excessive number of communication participants with an excessive or insufficient number of repetitions for message recognition. There is also no possibility of parallel transmission in time (in case of emergency: emergency stop, drop in cargo, etc.) of voice messages addressed to the drivers of neighboring trains, and at the same time conducting the necessary negotiations with the train dispatcher. This slows down the dissemination of urgent information, generates the spread of inaccurate and unnecessary information, and ultimately creates the prerequisites for violations of the technological discipline of dispatch control of train traffic.

The technical result of the invention is to increase technological discipline by increasing the efficiency and reliability of the formation and transmission of critical messages by train radio.

The technical result of the invention is achieved by the fact that in the control system for the transmission of messages by train radio communication, containing at the central station of the dispatch control the workstation of the train dispatcher, the personal computer of which is connected via a digital communication interface to a stationary control radio station, which is connected to stationary via a wire channel of dispatch communication radio stations of intermediate stations, each of the stationary radio stations via digital the radio channel is connected to the on-board radio stations of locomotives located in the stable radio communication zone, and the on-board radio station of the locomotive is connected to the on-board digital communication interface according to the invention, according to the invention, a locating unit for the location of the train and a message generation unit are installed on the locomotive, which are via the on-board digital communication interface connected to the on-board control device, and a message server is installed at the central control station es digital communication interface connected to a PC workstation train dispatcher.

The drawing shows a structural diagram of the proposed control system for the transmission of messages by train radio.

The train radio communication message management system contains, at the central dispatch control station 1, a train dispatcher workstation 2, the personal computer 3 of which is connected via a digital communication interface 4 to a stationary radio control station, which is connected to the stationary radio stations 7 of the intermediate stations via a control channel 6 and each of the stationary radio stations 7 through a digital radio channel 8 is connected to the on-board radios and 9 locomotives 10 located in a stable radio communication zone, and the on-board radio station 9 of the locomotive 10 is connected via the on-board digital communication interface 11 to the on-board control device 12, on the locomotive 10 there is a block 13 for determining the boundaries of the location of the train and a block 14 for generating messages that are via the on-board digital the communication interface 11 is connected to the on-board control device 12, and a message server 15 is installed at the central control station 1 1, which is connected via a digital communication interface 4 to a personal computer 3 workstation 2 train dispatcher.

The control system for the transmission of messages by train radio operates as follows.

As the locomotives 10 move, the on-board radio station 9 of each locomotive 10 listens on the air at different frequencies (intended for communication channels) to select a stationary radio station with which the best communication can be organized. To call the train, the train dispatcher dials the corresponding number using the keyboard (not shown in the drawing) at the workstation 2. The code message contains the locomotive number 10 to which it is addressed. The system also provides for a group call of locomotive drivers 10. The address codogram is transmitted alternately by all stationary radio stations 5 and 7 at all frequencies of digital radio channels 8. It is received by the on-board radio stations 9 of each locomotive 10 and is compared with the number dialed by the driver before traveling on the control panel of the on-board radio station 9 locomotive 10. If it coincides at a certain transmission frequency of the transmitted number with the number of the on-board radio station 9, it transmits a signal of confirmation of acceptance of codograms corresponding to the stationary radio station 5 or 7. Further confirmation signal through a wired channel 6 dispatch communication is transmitted to the fixed station assignments 5, and it provides only a further link between a corresponding pair of the locomotive and a stationary radio stations to connect. In the process of negotiations, the driver, to call the train dispatcher, presses the calling function key on the remote control of the on-board control device 12, and then (if necessary) can press the function key to automatically generate the desired message from the standard set of messages. The number of the called train and the text of the transmitted message appear on the display of the workstation 2 of the train dispatcher. The train dispatcher, depending on the type and content of the message, transmits a command to locomotive 10 in response to it or enters into negotiations with the driver. If during the busy period of the channel there is a need for urgent transmission of information to the train dispatcher, the driver can use the emergency call function key. In this case, regardless of the location of the locomotive, its channel of communication with the train dispatcher is organized, and the driver announces the reason for the emergency call by voice. In case of emergency, at the same time as calling the train dispatcher, the engineer can send an emergency voice message of a predetermined form from a given set of messages via a group emergency call channel for all locomotives. Messages are automatically synthesized by the message generation unit 14 depending on the pressing of the corresponding function key on the remote control of the on-board control device 12. Each such message is a standard phrase with optionally inserted variable data received from the on-board control device 12.

For example, after an emergency stop of the locomotive, the on-board control device 12 determines the coordinates of the location of the head and tail of the train through the unit 13 for determining the boundaries of the location of the train. For this, all subsystems of the on-board control device 12 are used, allowing together to calculate accurate and reliable information. For example, if the on-board control device 12 includes the well-known KLUB-U subsystem (see RU 2248899), then information from the on-board GPS receiver, a wheel sensor of the distance traveled, and also information about the length of the train are used to determine the coordinates by the block 13 for determining the location of the train and route plan information from an electronic route map.

The calculated coordinate values are used by the message generation unit 14 to determine the name of the nearest point and distance from it in kilometers and pickets by the railway identification system for the head and tail of the train on the electronic map of the route in the on-board control device 12.

For example, the message may appear on the display of the on-board control device 12 as follows: "Train No. 111, following in the direction from the Lesnaya station to the Ozernaya station, was stopped by the emergency braking system at the 21st kilometer near the 4th picket at 16 hours 12 minutes. The end of the train is located on the 20th kilometer near the 8th picket from the Lesnaya station. "If the train driver confirms the information presented in the generated standardized message, the message is provided with a confirmation sign and the boron is sent immediately the new control device 12 through the on-board radio station 9 via the group channel to all nearest locomotives (usually the radius of the direct communication between the radio stations 9 is at least 10 km) and separately through the stationary radio stations 7 of the intermediate stations, the wired dispatch communication channel 6, the stationary control radio station 5 and through the local a digital communication interface 4 to the message server 15. The sending of the message is stored using the registration device of the on-board control device 12. If the train driver does not press the function key or does not confirm the information, then after a short period of time, emergency messages are generated by the system and are automatically sent and recorded with a sign of the driver’s absence of participation. Depending on the category of train, the content of emergency messages may vary. For example, during an emergency stop of a freight train, it is necessary to warn the trains following the adjacent tracks about the possibility of a fall of cargo along these tracks, which may have broken off the train during emergency braking.

If necessary, the server 15 messages based on the primary text message can synthesize the corresponding voice message. Text and voice messages are transmitted to a personal computer 3 of the workstation 2 of the train dispatcher for subsequent playback. To play a voice message as part of a workstation 2 there is a device for reproducing sound. In accordance with the priority of importance, the personal computer 3 displays messages from the message queue and displays a text message queue for the train dispatcher. The train dispatcher sends a recognition signal for the next message to locomotive 10 and then makes a decision to relay it to other participants in the process with additions and changes that he can enter via the keyboard of workstation 2. Messages can be sent to the drivers of trains adjacent to train No. 111, list which can be generated automatically in a personal computer 3, for example, by a request to the subsystem for monitoring the execution of a traffic schedule (URAL GUIDE), or teams am maintenance. The response text and voice message from the train dispatcher, preceding the start of the dialogue with the calling train driver, can be generated automatically in the workstation 2 by pressing the corresponding function key. After that, it can be automatically sent to train number 111. This may be the answer of the following content: "To the train driver No. 111, the train dispatcher understood you, wait your turn for a voice communication session within 2 minutes." This message is reproduced on the locomotive in the form of text and / or voice message using the on-board control device 12, which includes a voice informant. The fact of receiving a message from the train dispatcher by the locomotive driver 10 and its subsequent recognition can be confirmed for the train dispatcher by sending a standard response message from the locomotive, each time after the operator presses the confirmation function key in the on-board control device 12. For example, it could be an answer like: "The train driver No. 111 understood the message from the train dispatcher."

Then, simultaneously with the automatic distribution of standardized messages, the driver and the train dispatcher can conduct the necessary negotiations on a separate communication channel.

Thus, the proposed system provides: parallel transmission of emergency messages from a given locomotive to other locomotives and to a train dispatcher, accurate wording of the place and causes of events. Important parts of the dialogue between participants in the movement occur automatically and are recorded in a clear standard form. All together, this helps to accelerate actions to control traffic and increase technological discipline.
