Description

The utility model relates to communications and can be used in technological communication systems in rail transport.

A known system of duplex dispatching train operational technological radio communications - PRS-330 (Yu.V. Vavanov "Technological railway radio communication", M., "Transport", 1985, p.140-151). The operational-technological radio communication system contains stationary radio stations located along the railway, and a control station located in the control center, a duplex radio communication channel is organized between the dispatcher and the train driver, as well as between the train driver and the duty stations on the railway stations located on the railway section, equipped with this radio communication system. The system allows you to make an individual call to the driver by train number from the train dispatcher (DSC) and an individual call to the DSC from the driver. To call the station attendant (DSP) from the train driver, a group call is used in two ways - calling the "nearest DSP" or all DSPs in the entire section. The latter is used if the driver needs to call a “long-range chipboard”. There are also two options for calling a train driver from a chipboard. If the desired driver could not be called in “his” zone, the chipboard should use the call throughout the area.

The disadvantage of the system of duplex dispatching train operational-technological radio communication is that when calling a chipboard, the driver must evaluate his location and make a choice between the two methods of calling, which reduces the efficiency of his work. When using the call mode "distant chipboard" on the site, it becomes impossible to call for the second pair of chipboard driver. Particleboard does not have the ability to individually call the train driver by train number. There is no way to contact employees on the way in the system. A separate radio communication system should be used for these purposes.

During negotiations between the DSC with the train driver of a train, communication between the chipboard and the train driver of another train located in the same zone is not possible due to the presence of only one radio channel in the system.

The technical result of the utility model is the creation of a system that ensures the integration of technological radio communication systems of railway transport and the expansion of their functionality through the use of a digital radio channel.

The technical result of the utility model is achieved by the fact that in a digital technological radio communication system of railway transport containing base radios, portable locomotive radios, portable radios, control panels of the dispatching apparatus and subscribers of railway services and a switching center, according to the proposal, the switching center includes a server, a controller -switch, multiplexer and gateways, while the control panels of the dispatching apparatus and subscribers of railway services through the corresponding e gateways are connected to the controller-switch, which is connected to the server, and through the multiplexer, the controller-switch is connected to the communication channel to which the base station is connected via an additional multiplexer, the locomotive radio station is equipped with a controller through which it is connected to the memory unit for storing the database and remote control locomotive radio station.

The proposed system with the above set of features, which is a hardware-software complex of a radio communication system, implements the principles of forming group and individual call zones by automatically updating the list of available subscribers and groups of subscribers in the locomotive station, depending on which base station of the system is currently a locomotive radio station is registered, as well as in accordance with the numbering plan. From the database, a correspondence data table of the form “base station number - data table” corresponding to the number of the base station is sent to the controller. When registering a locomotive radio station in another base station, another data table is transferred to the controller from the database. In the application server of the switching center, a correspondence table is compiled of the form “train number - locomotive radio station number from which a message was received with the given train number”, the application server sends the compiled table to all control panels on duty at the stations and dispatchers connected through the switching center gateways. Individual and group numbers for calls to subscribers change when the train is moving from one base station to another.

The communication between the locomotive radio station and the base station is carried out via the radio channel (TETRA standard radio interface), the communication between the base station and the switching center is via E1 channels, the communication between the control panels of station attendants, train and power dispatchers is via Ethernet lines.

The system implements integrated algorithms for the exchange of information with trains, including high-speed ones, and ensures the maintenance of the required functionality, including individual, group and broadcast calls, call priorities, interruption of a call when an emergency call arrives.

The algorithm of the digital technological radio communication system ensures the operational control of the technological process, the simplicity and comfort of use of the system by railway workers, which increases the safety of train traffic, especially on high-speed railways.

The figure shows a structural diagram of a digital technological radio communication system of railway transport.

The digital technological radio communication system of railway transport contains base radios 1, portable locomotive radios 2, portable radios 3, control panels (4, 5, 6, 7 and 8) for the control of the dispatching apparatus and subscribers of railway services and a switching center 9, which includes a server 10, the controller-switch 11, the multiplexer 12 and the block 13 gateways, control panels (4, 5, 6, 7 and 8) of the control apparatus and subscribers of railway services through the corresponding gateways of the block 13 are connected to the controller-switch 11, which is connected to the server 10, and through the multiplexer 12, the controller-switch 11 is connected to the communication channel 14, to which the base station 1 is connected via an additional multiplexer 15, the locomotive radio 2 is equipped with a controller 16, through which it is connected to the memory unit 17 for storing the database and remote control 18 locomotive radio station 2.

The system of digital technological radio communications of railway transport operates as follows.

The locomotive radio station 2 is located in the locomotive cabin of each train, interacting with other subscribers using the base station 1 and the switching center 9. Through a locomotive radio station 2, the train driver interacts with station duty officers using the station control panels (4, 5, 6), as well as with the train dispatcher and energy manager using the train manager control panel 7 and the energy manager control panel 8, respectively, or with an employee on the way using a portable radio station 3.

When implementing a digital technological radio communication system on a railway section, several dozens of base stations and control panels for station attendants, several units of train dispatcher control panels, energy dispatcher control panels, one switching center, and several hundred portable radio stations designed for those working on the track can be installed .

When a train enters a specific section, a locomotive radio station is automatically registered at the base station, the locomotive radio station controller receives the base station number, the switching center receives the number of the registered locomotive radio station from the base station, and the train driver automatically invites the train driver to enter the train number for receiving calls from the receiver of the locomotive radio station, the controller of the locomotive radio station monitors. When a train moves from the coverage area of one base station to the coverage area of another base station, a locomotive radio station is registered in another base station.

Communication between locomotive radio station 2 and base station 1 is via a radio channel (TETRA standard radio interface), communication between base station 1 and switching center 9 is via E1 channels, communication between control panels of station attendants, train and power controllers is via Ethernet lines.

The following subscribers and the equipment of the radio communication system participate in the interaction of the subscribers of the software and hardware complex.

If you need to contact any subscriber, the driver on the control panel 18 of the locomotive radio station 2 presses the button with the designation of the desired subscriber or dials the desired number, sends a call. In the first case, the call sent also contains information about the number of the called subscriber (group of subscribers), which is generated automatically depending on which button was pressed. The call is received by the base station 1 and is transmitted to the switching center 9. The center 9 switching commutes the received call to the desired subscriber. If the required subscriber is the station duty officer or dispatcher, the call is switched to the appropriate control panel. If the required subscriber is an employee on the way, switching to base station 1 (the same or another) is performed, and then broadcasting to the radio channel to portable radio station 3 of the required subscriber.

The train driver next work algorithm.

When a train enters a section of a railway on which a digital technological radio communication system is operating, the locomotive radio station 2 installed on this train is automatically registered at base station 1, in the coverage area of which the train was at a given time. The procedure is two-way: the controller 16 of the locomotive radio station received the number of the base station 1 in which registration took place; the switching center 9 received from the base station 1 the number of the registered locomotive radio station 2.

After registration, the controller 16 of the locomotive radio station 2 sends a request to the database recorded in the memory unit 17 of the locomotive radio station 2. From the memory unit 17, a data table corresponding to the number of the base station is sent to the controller 16. Previously, in the memory block 17 (in the database) of the locomotive radio station 2, correspondences of the form “base station number - data table” are entered. The data table is a list of individual and group numbers that may be relevant while locomotive radio station 2 is in the coverage area of this base station 1.

At the next time, the control panel 18 of the locomotive radio station 1 automatically receives an invitation to the train driver to enter the train number. The train number is unique at a given time in this section. The train number differs from the number of the locomotive radio station and varies depending on which route the train is traveling. The driver using the buttons on the remote control 18 of the locomotive radio station 2 dials the train number. The train number is automatically transmitted through the base station 1 to the application server 10 of the switching center 9. In the application server 10 of the switching center 9, a correspondence table of the form “train number - locomotive radio station number from which a message is received with the given train number” is compiled. The application server 10 sends the compiled table to all control panels of station attendants and dispatchers connected through the gateways of the block 13 of the switching center 9.

The controller 16 of the locomotive radio 2 monitors the pressing of buttons on the remote control 18 of the locomotive radio 2 and the receipt of calls from its receiver.

The train driver has the opportunity to call the officers on duty at the station of the railway station within which or near which he is located, the station from which he has departed, and the station towards which he is moving. To do this, it is possible to use individual calls “Particleboard near” 4, “Particleboard on the left” 5, “Particleboard on the right” 6 (moreover, in the list of available subscribers that appears on the indicator panel of a locomotive radio station after registration in each base station 1, the names of specific railway stations). It is possible to use a group call, in which the call will be received not only by several chipboards, but also by train drivers located in a certain area. This implements the call function driver-driver. Individual and group numbers for these calls should be different for cases of registration of a locomotive radio station in different base stations. In addition, the train driver should be able to call “his” train dispatcher, and in some cases, “his” energy dispatcher. For this, individual calls are used. The individual numbers for these calls should also change when the train passes from one base station to another.

If any button is pressed on the control panel 18 of the locomotive radio station 2, the controller 16 determines which button was pressed. Depending on the pressed button, the controller 16 finds a correspondence in the data table to an individual or group number and sends a corresponding call through the transmitter of the locomotive radio station 2. If the permitted combination of buttons is used on the control panel 18 (for example, digital dialing has been performed), which does not correspond to the data table, a call is generated by the dialed number.

The driver should be able to receive an individual call from the DCC, ECC, chipboard, as well as a group call in the group of chipboard drivers from the chipboard and other train drivers located in a particular section.

If any call was received from the receiver of the locomotive radio station 2 by the number of the locomotive radio station, the controller 16 analyzes the number of the subscriber who sent this call to find its correspondence to any number contained in the data table for the current base station. The same is true for a group call. When any match is found, the controller displays the corresponding message with the name of the calling subscriber on the control panel of the locomotive radio station. If no match is found, the controller displays the caller's number on the control panel.

When following a train along a railway section, the train moves from the coverage area of one base station to the coverage area of another base station. In this case, the locomotive radio station is registered in another base station, another data table is transferred to the controller 16 from the memory unit (database) 17. The process of establishing connections is carried out as described previously.

The algorithm of the station duty officer is as follows.

The controller of the control panel of the station duty officer 4 (5, 6) monitors the state of the buttons on the control panel and the incoming calls from the wire line. The control panel for the station attendant is programmed in advance in accordance with the numbering plan, depending on which railway station it is installed in - the numbers of groups in which the station attendant can work can be entered into the console, certain buttons are also programmed so that when pressed they were formed calls to certain numbers - individual or group. The station attendant should be able to call, using a group call, train drivers who are currently near the railway station at which the station attendant works. The station attendant should be able to receive a group call from train drivers who are currently near this station. To do this, the number of the group in which the calls are sent or received to or from the train drivers must coincide with the number of the group in which the train driver sends or receives calls when they are near the given railway station.

The same applies to the challenges of workers on the way.

If the combination of the “Train No.” and “1111” buttons is dialed on the remote control, the controller views the correspondence table “train number - locomotive radio station number” and generates an individual call by the locomotive radio station number, which corresponds to train number 1111. If an individual call is received to the console, the controller scans the correspondence table “train number - locomotive radio station number”, when finding a match, the message “Train train ...” is displayed on the console indicator. If such a match is not found, the message “Call from NNNNN” is displayed on the console indicator.

Thus, the proposed system of digital technological radio communications of railway transport through the implementation of a new algorithm for the interaction of subscribers of a digital technological radio communication system allows for efficient process control, simplicity and comfort of use of the system by railway workers, taking into account the peculiarities of operation on the road network, which increases the safety of train traffic.
