Description

The utility model relates to systems of automation and telemechanics in railway transport and can be used to automatically set the routes of trains in the coverage area of the train dispatcher post.

A known system of control of technological discipline of the process of controlling the movement of trains, collecting data from technical means of railway automation and telemechanics and their transmission to the central processing complex, processing and analysis, communication with workstations, performs the functions of monitoring technological discipline, staff training, operational support system decision-making at the level of the road traffic control center, train safety, includes integrated loco an otivy safety device interacting with the traction rolling stock over the air using radio modems and an inter-circuit interaction system, while collecting data from the complex locomotive safety device and railway automation and telemechanics, processing and preparing them for transmission to the traction rolling stock is carried out at assistance of the control computer complex, includes on-board control devices, a digital interaction device that provides interaction operation with an automatic railway control system, on the one hand, and with on-board devices, on the other, a transportable radio station, a digital radio communication system that provides communication with the central processing complex controlling the traction rolling stock, a central web portal that analyzes the data presented from the central processing data complex in visual form (RU 2307041 C1, 09.27.2007).

The known system improves the quality of management and the efficiency of the rolling stock, the control of technical means of the railway complex and technological processes during the movement of trains, however, it does not provide automatic installation of train routes at the control station.

The closest analogue is the centralized dispatch system, which provides for the automatic installation of train movement routes (station Post of centralized dispatch in Portugal, Railway of the World Railway, No. 5, 2002).

The system operates on the basis of information from the route setup table and data on the location of the train coming from a tracking system for its movement. Routes are set automatically in the entire coverage area of the train dispatcher post (DC). The route setup table contains, in particular, the train number, route information and the criteria for their installation. If this criterion is met, the system first checks the possibility of setting a route. If the test result is positive, a command to set the route is issued. If, for any reason, the route is not established within the specified period, then the operator is issued with relevant information. Along with the manual mode, when the operator enters the installation of routes, the system can operate in automatic and semi-automatic modes.

In automatic mode, the system determines the installation time and route parameters independently. The command to set the route is issued without operator intervention. In semi-automatic mode, the system works the same as in automatic mode, but confirmation of the operator is necessary to issue a command to set the route.

Route control may or may not work, not only for certain trains, but also for certain outdoor signals. If a train is not included in the train route setting table, they are not automatically controlled for this train. If the train is included in the route setting table, but is in front of a signal for which the automatic route setting control mode is turned off, the system cannot establish a route that includes this signal.

The known system operates on the basis of information from the route setup table and data on the location of trains coming from a tracking system for their movement, and is not related to the train schedule. Moreover, the preference for the formation of orders for the installation of routes is given to the operator.

In the event of a deviation from the route setup table, the known system loses its functionality and switches to the “manual” mode of operation.

Moreover, the known system does not have the ability to dynamically recalculate the order of the passage of the train in the event of malfunctions and failures in the operation of electrical centralization and automatic blocking.

The objective of the invention is the creation of an automatic control system for the movement of the train, providing the functions of automatic formation of tasks for setting routes, tracking the timely and safe passage of trains of a controlled dispatch section.

The technical result consists in increasing the efficiency and safety of the system of automatic installation of train movement routes, as well as in minimizing the loss of throughput and carrying capacity in the dispatch area.

This is achieved by the fact that the system of automatic installation of train movement routes contains a train pass planning module with a database of valid control orders, connected via a two-port gateway to the workstation of the train dispatcher (AWC DSC), additionally including a database of control orders, a route database, a block analysis and pre-processing of control orders, a unit for monitoring the status of routes and a communication support unit, while the output of the train pass planning module in through a series-connected two-port gateway and communication support unit is connected to the input of the control orders database, the output of which is connected to one of the inputs of the control orders analysis and pre-processing unit, connected by the other input to the route database output, which synchronizes the output of the valid database connected to the corresponding input control orders of the train admission planning module, the input of which is connected through a series-connected two-port gateway and a communication support unit to the output of the route status control unit, one of the inputs of the control actions generation unit, the logical control unit of electric centralization and automatic blocking devices, and the route state control unit is connected via tele-signaling channels with linear devices of electric centralization and automatic blocking (EC and AB) connected via channels remote control to the output of the control actions generation unit, the other output of which is connected to the second input of the ma route, and the first and second inputs, respectively, with the outputs of the block of analysis and preliminary processing of control orders and the block of logical control of the correspondence of the linear devices of the EC and AB connected to the output of the base of the algorithms of linear devices of the EC and AB

The essence of the proposed system is illustrated in figure 1, which shows a structural diagram of the proposed system for the automatic installation of train routes.

The system of automatic installation of train movement routes includes a train passing planning module 11 with a route data base 9 connected via a two-port gateway 1 to a workstation 14 of a train dispatcher (AWC DSC), additionally including a database of 3 data of control orders, a base of 4 routes, block 5 analysis and preliminary processing of control orders, block 6 monitoring the status of routes and block 2 communications. At the same time, the output of the train passing planning module 11 through the serially connected two-port gateway 1 and the communication support unit 2 is connected to the input of the control orders data base 3, the output of which is connected to one of the inputs of the control orders analysis and preliminary processing unit 5, the other input of which is connected to the output a base of 4 routes, with a synchronizing output connected to the corresponding input of a base of 9 data of permissible control orders of the train passing planning module 11. The output of the route condition monitoring unit 6 is connected through a series-connected communication unit 2 and a two-port gateway 1 to the input of the train admission planning module 11. One of the inputs of the control action generation unit 8 and the logical control unit 7 for electric centralization and automatic blocking of the automated workstation DNTs 14, as well as the route status control unit 6 is connected via remote signaling channels 12 to the linear electric centralization and automatic blocking devices 13 (EC and AB), connected via telecontrol channels 10 to the output of the control action generation unit 8, the other output of which is connected to the second input of the route status control unit 6, and the input is output block 7 house of logical control of the correspondence of the linear devices of the EC and AB connected to the output of the base 15 of the algorithms of the operation of the linear EC and AB devices.

The automatic route setting system automatically controls the movement of trains within the control section by setting up the routes for receiving / departing trains in accordance with control orders generated by the train passing planning module 11.

A control order is an indication of an operation to receive, send or track one train at one of the stations in the dispatch area. In essence, the control order includes a mnemonic designation of the route, as well as an identification code, by the value of which a route is searched for in the base of 4 routes. An element of the route list is a structure containing the composition of the route (rail chains, arrows, traffic lights, etc., as well as the code for the corresponding telecontrol command).

At the same time, information on admissible control orders to the database 9 is entered into module 11 from AWP DSC 14 at the stage of adaptation of information support and the database of AWP DSC 14 to a specific dispatch area.

When setting the train route, module 11 generates control orders for the installation of train routes and transmits them via a two-port gateway 1 to the isolated local computer network of the dispatch center (LAN DC) (not shown in Fig. 1), to which the AWC 14 is connected.

Gateway 1 is made in the form of hardware-software means of industrial (rack-mount) performance, equipped with two network cards, one of which is connected to the corporate data transmission system (SPD) of Russian Railways, and the other to the LAN of the data center. Specialized software installed on the gateway 1, performs filtering and transmission of traffic between network cards. Thus, the gateway 1 provides a secure data exchange between the SPD and the DC LAN in the absence of their physical association.

The communication support unit 2 receives control orders from the train admission planning module 11 and transmits information about the current train position and the status of previously received control orders in accordance with the information interaction protocol. The main function of the communication support unit 2 is to promptly detect the disconnection between the module 11 and the AWS of the DSC 14, inform about the need for an emergency exit from the automatic control mode and transfer control to the train dispatcher.

The accepted control orders are stored in the database 3 of the control orders data. The control orders analysis and pre-processing unit 5 carries out sequential selection of control orders from the control order database 3, determines the authenticity of the control order, namely, whether the control order is actually generated by module 11, and whether the selected control order belongs to this dispatch area.

In the event that the control order satisfies the above conditions, the control orders analysis and preliminary processing unit 5, using the database 4 of valid routes for this dispatch section, forms a sequence (series) of train reception / departure routes providing for the implementation (execution) of the control order.

The selected routes enter block 8 of the formation of control actions. For each of the selected routes, based on the results of the operation of the logical control unit 7 and information on the current train position obtained through the remote signaling channels of the linear devices 13 for electric centralization and automatic blocking (EC and AB), in block 8, an assessment of the possibility of execution (installation) of this route.

In this case, the block 8 of the formation of control actions blocks the execution of the order to set the route in the event that:

- The rail circuit in the route is busy.

- the rail circuit in the route is closed.

- the departure lane is busy (the busy lane busy signal is active) and deployed in the opposite direction (only for departure routes).

- the rail chain located immediately beyond the end of the route is busy (only for departure routes).

- from the neighboring station, the departure route to the departure route of this route is open (only for departure routes).

- at a nearby station, the departure route to the departure route of this route is set (only for departure routes).

If at least one of the routes of the series cannot be installed, block 8 generates a corresponding message for block 6 monitoring the status of the route.

The sending of telecontrol commands begins only if it is permissible to set all the routes from the series. In this case, the control action generation unit 8 transmits a command to set the route through the channel-forming equipment of the central post of the data center (not shown in the diagram) to the telecontrol channel 10, then to the line point of the data center and, as a result, to the actuators of the linear devices 13 EC and AB .

After sending the command to the channel 10 telecontrol, during the exposure time, block 6 performs continuous monitoring of the installation of the route. The exposure time is configured separately for each route in the process of adapting the workstation database of the DSC to a specific dispatch area. In the event that the execution of the route setup command is not completed during the exposure time, the transmission of the next command from the series is interrupted, and block 8 generates a message for the route condition monitoring unit 6 about the failure in the route setting process.

Block 7 of the logical control of compliance of the dependences of electric centralization and auto-blocking devices is an integral part of the workstation of DSC 14. Using algorithms formalized in the database of 16 operation algorithms of signaling devices and information about the current train position received through the tele-signaling channels 12, logic control block 7, regardless of control mode (automatic, "manual"), performs continuous monitoring of the operation of linear devices 13 EC and AB in order to identify their abnormal conditions. The states detected by block 7 of logical control include violations of the logic of the track chain, false employment and false freedom, unauthorized transfer, unauthorized loss of control of arrows, mutually exclusive indications of traffic lights, malfunctions of a control-dimensional device (KSU), devices for monitoring the rolling stock (UKPSS) and other contingencies.

In the event that an abnormal condition is detected for the linear device 13, all control actions, including the receiving / sending routes in which this linear device 13 is involved, are considered as potentially dangerous and are blocked up to a special order.

Block 6 monitoring the status of the route is intended to store information about the status of control orders received in AWP 14 of the Information Center and informing module 11 about the progress of their execution. The state of control orders is formed on the basis of the current train position and messages of block 8 of the formation of control actions about the impossibility of executing one or another control order. Messages are generated for module 11 sporadically, upon the fact of a change in the state of one or more control orders.

A control order may be in one of the following conditions:

- a control order was received from the module for constructing a train pass schedule

- the remote control command to set the route was sent to the remote control line.

- the route is being set (there is a time delay for setting the route).

- the route is set.

- the route is being investigated.

- route investigation completed.

The transmission of information is carried out by means of the communication support unit 2 in accordance with the information interaction protocol.

If it is not possible to automatically set the route, module 11 notifies the train dispatcher of the need to take control for themselves, for which information about the need to switch to the dispatch mode through gateway 1, the communication unit 2 is sent to the hardware and software device of Workstation DNTs 14, notifying the train dispatcher of the transfer management. The train dispatcher, in accordance with the operating situation at the station, forms the route of the train and sends them to block 8. From the output of control unit 8, the corresponding commands are sent via telecontrol channel 10 to actuators of linear devices 13 EC and AB. The results of the route formation through the tele-signaling channels 12 are sent to the subsystem 7 for monitoring the devices of the EC and AB to monitor the status of the linear devices 13 of the EC and AB and are displayed on the video terminal AWP DNTs 14.
