Description

The utility model relates to railway transport and can be used in automated dispatch control systems on single-track railways with double-track inserts.

A known system for controlling the movement of trains on single-track railways, comprising a control tower connected via a trunk line to electronic centralization on-line devices connected to automatic locking devices with rail circuits (see WO 0128839, 04/26/2001). The known control system allows overtaking or crossing trains while trains are at intermediate stations having at least two railway tracks. In this case, permission to receive a train to an intermediate station from a single-track span adjacent to the station, and permission to send a train to a free single-track span adjacent to the station is carried out by opening the corresponding input or output traffic light with the help of centralization guards controlled by the dispatch center.

A disadvantage of the known control system is the low level of automation due to the lack of detailed information about the situation on the route of the train in the driver’s cab, which reduces the driver’s confidence that the train is free to move and, therefore, reduces the capacity of the transport path.

There is a known system of interval traffic control during centralized control, in which safe speed and the interval between the following trains are automatically supported by locomotive on-board devices that receive initial information about the coordinates of their and neighboring trains at the control section from the control center, as well as from neighboring trains via satellite channels navigation and communications (see JP 2000318613, 11.21.2000).

A disadvantage of the known system is the lack of reliability due to the presence of areas of poor reception for satellite communications and the lack of control of kinked rails, which limits their scope.

The closest analogue to the claimed utility model is a control system for the movement of trains on single-track railways with centralized dispatching and a system for organizing it (see A.A. Kazakov, Automation regulates the movement of trains, Fig. 11, M .: Transport, 1986) .

The known system for controlling the movement of trains on single-track railways in centralized dispatching includes a control center connected via line trunk communication devices to electrical centralization stations limiting single-track line spans connected by self-locking devices with rail circuits and centralized station arrows.

The known control system allows overtaking and crossing trains while they are on double-track inserts, while allowing the train to be received at the double-track insert from the adjacent single-track span and permitting the train to go to a free single-track span adjacent to the double-track insert by opening the corresponding input and the exit traffic light, and the freedom and integrity of sections of the railway track is controlled using centralized arrows, rail chains of devices lining and electrical centralization. Moreover, for non-stop overtaking and crossing trains, the arrival of trains at an intermediate station is synchronized in time by negotiation between the drivers and the dispatcher for train radio communications.

A disadvantage of the known control system is the low level of automation, due, in particular, the lack of detailed information about the situation along the route of trains in the driver's cab. This reduces the driver’s confidence that the trains are provided with safe unhindered passage through the double-track insert, and, consequently, cause a decrease in the speed of the train for its safe movement, which reduces the throughput of the transport path.

The technical result consists in increasing the throughput and efficiency of running trains on a single-track railway with double-track inserts by providing the locomotive driver and dispatcher with detailed information about the situation along the train route.

The technical result is achieved by the fact that in the system for controlling the movement of trains on a single-track railway with double-track inserts, containing a control center connected via a trunk line to the postal devices of electrical centralization of stations limiting single-track line spans connected to the corresponding self-locking devices with rail circuits and centralized arrows, according to the utility model, use guard devices of electrical centralization, including This is an excellent means of controlling the pressure of the wit of arrows, and the on-board control devices of train locomotives are equipped with on-board satellite navigation receivers and graphic displays and are connected via a digital communication channel to a control center.

Moreover, the digital communication radio channel can be made on the basis of a slotted waveguide laid along the railway track. This implementation of the communication channel allows for reliable communication, including in tunnels and mountainous terrain.

The invention is illustrated in the drawing.

Figure 1 shows the structural diagram of a control system for the movement of trains on a single-track railway with double-track inserts.

The control system for the movement of trains on a single-track railroad with double-track inserts contains a double-track insert 1 with adjacent single-track stages 2 and limiting stations 3, equipped with automatic locking devices 4 with rail circuits and centralized switches connected to the postal devices 5 for electrical centralization (EC). The postal devices 5 for electric centralization additionally include means for controlling the pressure of the wit of arrows (not shown in Fig.) Located directly on the arrows. The control center 6 is connected via the trunk communication line 7 to the postal devices 5 of the EC, and via the radio channel 8 of digital communication to the on-board device 9 controls the locomotive 10 of the train involved in the dispatch control. The on-board device 9 for controlling the locomotive of each train is connected to the on-board receiver 11 for satellite navigation and a graphic display 12. Moreover, the digital communication channel 8 can be made on the basis of a slot waveguide laid along the railway track.

The control system for the movement of trains on a single-track railway with double-track inserts works as follows.

In the normal implementation of non-stop movement, for example, crossing two oncoming trains P1 and P2 at a double-track insert 1 due to the interaction of on-board devices 9 for controlling locomotives 10 with a control center 6 for controlling a train, they approach the station simultaneously or with an acceptable time difference. In the dispatch center 6, the receiving routes for each train П1 and (П2) to the double-track insert are set in advance before it enters the adjoining single-track stage 2. With manual control of the train П1 or П2 (without a car driver), this ensures that it is guided by the driver.

At the same time, when the centralized arrows N and P are triggered, the EC 5 post device generates a control signal at the corresponding output, including automatic continuous monitoring of the pressing of the arrow points. The signals characterizing the state of the pinworms of the shooters, from the output of the means of monitoring the pressing of the shooters of the arrows arrive at the postal devices 5 EC, and then to the dispatch center 6.

The dispatch center 6 transmits information about the position of the arrows of the double-track insertion via the digital communication channel 8 to the on-board control device 9 of each train and then to the graphic display 12. Moreover, the information received from the EC 5 postal devices characterizes both the position of the arrow itself and the state of pressing it wits.

The on-board control device 9 is arranged to be displayed on the graphic display 12 while the train is maneuvering on the double-track insertion of the position of the arrows and the state of pressing its wit.

During the movement of each train, the satellite navigation receivers 11 of the locomotive 10 form the coordinates of their location and the location of the train adjacent to it and transmit this information to the on-board control device 9 for displaying them on the graphic display 12 and for transmitting it to the control center 6.

Dispatch center 6, on the basis of detailed information about the situation on the train route, forms receiving routes for each train П1 and П2 and transmits them to the on-board control device 9 of the corresponding locomotive 10. Full information transmitted to the digital communication channel 8 is generated in the control center 6 of the control.

On the graphic display 12 of the locomotive 10 of each train, the position of the arrows, the coordinates of the trains, as well as the permissible speed for the train to follow the input arrow of its route through the double-track insert and, if necessary, emergency stop the train at the double-track insert, the distance to the coordinate of the place of a possible emergency stop is displayed. Therefore, the train driver of each train also has detailed information on the situation along the train route.

When trains enter the station, they move along the station's tracks at a reduced speed. If, during the movement of train П1 to the exit traffic light Н2, train P2 completely releases its input arrow, and when the train П2 moves to the output traffic light Р2 train П1 completely releases its input arrow, then the dispatcher opens the output traffic lights Н2 and Ч2 for non-stop follow-up by trains П1 and П2 double-track insert 1.

Thus, drivers do not need to play it safe by further reducing the speed of the train when it moves along a single-track stage due to a lack of necessary information. The proposed system for controlling the movement of trains on single-track railways with double-track inserts provides increased throughput and efficiency of trains by providing the locomotive driver and dispatcher with detailed information about the situation along the train route.
