Description

CTC virtual rout-system for heterogeneous signal system operation and operation method using the same {CTC virtual rout-system for Heterogeneous Railway signal system operation}

The present invention relates to a CTC virtual career system for hybrid signal system hybrid operation, and more specifically, to configure the existing CTC control system by adding a "virtual path system" to mix and operate the heterogeneous signal system in the current CTC control system. CTC Virtual Career System for mixed operation of heterogeneous signaling system that supports efficient train operation control by supplementing the shortcomings of train number management.

As for the signaling system in operation in Korea, various signaling systems such as ATS, ATC, ERTMS LEVEL 1, ERTMS LEVEL 2, and ERTMS LEVEL 3 are established and operated according to the characteristics of the general railway and urban railway.

In the case of urban railroads, heterogeneous signal systems are not mixed and operated after a new control system is established by selecting a signaling system. However, various signaling systems are installed and operated for each railroad and high-speed railways according to each route, and the existing system is ERTMS LEVEL 2 Alternatively, the signal system may be changed to ERTMS LEVEL 3.

Therefore, in the control system, it is considered that it is necessary to construct a system so that heterogeneous signal systems can be mixed and operated.

It is necessary to improve the CTC control system so that the heterogeneous signal system can be mixed and operated in the existing CTC control system.

Currently, in the railroad control system that manages railroad operations, career information necessary for train operation is received and processed at the station.

 The route information received from the on-site station is divided into 'arrival route' for the train to arrive at the station and 'departure route' for leaving the station, and there is no information on the route between the station and the station, and only the train location information is displayed. do.

 If the location information of the train between the station or the station is missing due to other reasons such as an obstacle at the on-site station, or if the centralized traffic control (CTC) server operating in the railway control system fails, the train location and route information disappear, and the train control task Will have a blank space.

 The location and train number of the train in operation are important data to control train operation control and provide train destination information to customers.

In the existing CTC control system, train location (occupancy) information and route setting information of the corresponding station are received from interlocking installed at the on-site station based on the ATS or ATC signaling system, and the received path information and train location (occupancy) The train number is displayed by combining the information.

 The train number of the train outside the departure route of the on-site station is displayed by moving the train number based only on the train location (occupancy) information.

 However, if the train location information or course-related information is not received due to the problem of the on-site facility or the CTC control system, an error occurs in the relationship between the train number and the train location, and manual intervention of the controller is necessary.

In addition, as the frequency of manual intervention by the controller increases, a gap occurs in the train operation monitoring task, which may lead to a train accident as well as a decrease in satisfaction with customer service.

On the other hand, the train location and train number movement display is displayed on the CTC control system by combining train location (occupancy) information and route setting information received from field equipment.

 If it is not possible to receive train location (occupancy) information or route setting information from field equipment, the train location and train number movement information cannot be transmitted to the CTC control system using only the information from the CTC server.

When the CTC control system is normalized, after the controller re-collects information about the current location of the train and manually enters the location of the train number collected by the controller into the control system, the controller is responsible for controlling the train, etc. A normal return is possible.

In the conventional CTC control system, in order to automatically display and display train numbers, system clean-up time is required, and there is a problem that the system takes more than 20 minutes to return to normal.

The current railway control system logically combines, tracks, and manages train numbers and track occupancy information using the train location (track occupancy) information received from the site and the train schedule of the CTC server.

In addition, if there is a failure in communication with a train in discontinuous track occupancy information or a mobile occlusion system at a site station, the controller manually identifies the current location and number of the train and re-registers it with the control system.

Accordingly, there is a need to improve the CTC control system 100 so as to minimize the problems associated with mixed signal system operation by adding a virtual career system to the existing CTC control system.

Korean Patent Publication No. 2018-0001130 Korean Registered Patent No. 1687336 Korean Patent Publication No. 2010-0112815

The present invention has been made to solve the above problems, and by adding a virtual career system to the existing CTC control system, it is possible to minimize problems such as a case where a functional failure occurs between a field facility and a CTC control system according to mixed operation of a heterogeneous signal system. The aim is to improve the CTC control system.

In order to solve the above problems, the present invention is a CTC control system comprising an input / output unit composed of a console 12 and an LDP 14, a Com Server 40 that is a communication interface with the CTC server 10, and a communication network 50 ( 100) in the CTC virtual career system, including

It includes; a virtual path system (30) for receiving a train location information from the site and the route setting information of the field station to generate a virtual path between the station and the station.

The virtual route system 30 periodically synchronizes the CTC control system and the train number location information, and the train number movement of trains operating between stations is the information of the starting train number window and the ending train number window of the self-generated path. It is utilized to move and synchronize with the train number movement data of the CTC control system 100.

The virtual route system 30 manages the location information and the Excel counter information transmitted from the mobile occlusion type train, and corrects the train number and the location of the train by using only the virtual route information and the Excel counter information when a communication error occurs in the train. Combine and transmit to the CTC control system.

The virtual career system 30 sets a virtual course from the on-site station to the next station among the route information, and transmits the virtual route setting information to the CTC control system.

The virtual career system 30 stores the location of the train number included in the track information, generates movement information of the train number according to the track occupancy information according to the track information, synchronizes with the CTC control system, and track non-occupancy information In accordance with this, the release information of the virtual path is transmitted to the CTC control system.

The virtual career system 30 performs a virtual career zone remediation process when the train leaves the virtual career zone in which the train is running by non-occupied information among the track information, and transmits the remedy processing information to the CTC control system, It is determined whether additional virtual paths are set in the direction of the train, and is set if unset virtual paths are found.

The virtual course system 30 does not process the information on the route of arrival of the corresponding station among the route information, but does not process it in the virtual route system. In the case of setting information of the starting route, continuous virtual routes in the direction of the route are set. When the preceding train is in operation while setting the virtual route, or when the arrival route of the next station is found, the process of setting the virtual route is completed and the information of the completed virtual routes is sent to the CTC control system.

The virtual career system 30 includes track circuit number, track circuit occupancy, train number, continuous track information, course number, course classification, course setting, continuous course information, train number movement information, train location information, Excel counter information , And organization number mapping information.

In the present invention, the virtual career system 30 receives train location (occupancy) information from the field and career setting information of the field station;

The virtual path system 30 generates a virtual path between stations according to the route setting information.

After setting the virtual route through the virtual route system 30, the set state is maintained until the train runs, and after the train is operated, the virtual route is not set until the departure route of the entire area by the next train is set. Step; includes.

The virtual path of the preceding train through the virtual path system 30 is maintained until the next station arrives, and the virtual path of the subsequent train sets the virtual path only before the occupied track of the preceding train.

The virtual path system 30 does not set a path in units of tracks, but sets a continuous virtual path for each section from the current position of the train to the safety distance of the preceding train.

When the occupancy information of the train operating at a certain location is not displayed due to an error during operation in a certain location and the occupancy information is displayed only at a specific location, the virtual career system 30 occupies the train at the specific location. And confirming that the information is continuous information by train operation, and moving the train number remaining at a certain location that is the target of the virtual path to the next location.

The present invention made as described above, the present invention is to build a virtual career system in addition to the existing CTC control system, in the event of a functional failure between the on-site facility and the CTC control system according to the mixed-signal system operation, information retransmitted to the CTC control system By correcting the train position, the function of the CTC control system is additionally supplemented to prevent the economic damage caused by the delayed train operation by preventing the operation control of the train from being interrupted by the customer.

Also, in the present invention, even in a mobile occlusion system capable of communicating with a train, the train number and location information are transmitted from the train to the CTC control system, but when communication with the train is lost, the train number combined with the train number is Excel counter information in the virtual path. The system automatically connects to so that there is no gap in the control work.

In addition, the present invention can minimize the problems associated with mixed signal system operation by adding a virtual career system to the existing CTC control system.

 In addition, the present invention minimizes train delay and guarantees continuity of controller control tasks by restoring the minimum time for system failure, and improves customer-to-customer service satisfaction.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. In the present invention, a server and a system are used interchangeably, but its meaning and function are considered to be the same. This embodiment is provided to more fully describe the present invention to those skilled in the art. Accordingly, the shape of the elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same members may be indicated by the same reference numerals. In addition, detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the subject matter of the present invention are omitted.

3, the present invention is composed of a console (Console) 12, a large display panel (LDP) 14, a centralized traffic control system (CTC) 10, a Com Server 40, a communication network 50, and the like. It consists of a CTC control system 100 and a virtual route system (30).

The virtual route system 30 is configured to receive train location (occupancy) information from the site and route setting information of the site station as a CTC server, generate a virtual route between the station and the station, and transmit it to the CTC control system 100. .

In addition, the virtual route system 30 can be easily used even when the occupancy information of a train in operation is not displayed due to a conversion error during operation during a mixed operation of a heterogeneous signal system, and train occupancy information is displayed only at a specific location. Do.

Also, it is the same in the case of functional failure between the on-site facility and the CTC control system due to mixed operation of the heterogeneous signal system.

The CTC control system 100 and the train number location information are periodically synchronized, and the train number movement of trains running between stations is moved by using the information of the start train number window and the end train number window of the self-generated path. , Synchronize with the train number movement data of the CTC control system.

For example, a vehicle without an ERTMS LEVEL 2 or ERTMS LEVEL 3 on-board signaling device detects a train in the signaling system using a track circuit or an Axle Counter.

Here, the ERTMS train control device is classified into Level 1, Level 2, and Level 3, and a level suitable for the characteristics of the route is selected and installed.

When upgrading an existing line, it is installed in consideration of the interface between the in-vehicle signal facility of the train and the train control device of the link.

In addition, by managing the location information and the Excel counter information transmitted from the train of the mobile occlusion method, when the communication error occurs in the train, only the virtual route information and the Excel counter information are used to correct the train number and the location of the train and combine them into a CTC control system. Send.

On the other hand, during the operation of the control system of the present invention, there is a case where train location information cannot be received due to a defect in a field device or a communication error between the field and the control system.

As shown in FIG. 4, when the departure route <1> is set by the A0100 train at station A, the virtual route system 30 sets a virtual route between the station and the station until the arrival route <2> at station B.

At this time, after setting the virtual route, the setting state is maintained until the train operates, and after the train is operated, the virtual route is not set until the departure route of the entire area is set by the next train.

This is because if a virtual course is set in a situation where the starting route has not been set, it cannot cope if it is changed to another starting route.

Also, it is because the virtual route cannot be set when the train location information is not received due to a communication error between the site and the control system.

As shown in FIG. 5, when the preceding train A0202 <4> and the following train A0100 <3> are operated at the same time between the station and the station, the virtual path system 30 manages the virtual path according to the operating conditions of the train.

The virtual course of the preceding train A0202 <4> remains set until the next station arrival route, and the virtual route of the subsequent train A0100 <3> is set only before the occupied track of the preceding train A0202 <4>.

When the preceding train A0202 moves to the track of <5> according to the operation of the train, the virtual path system 30 additionally sets a virtual path for the operation of the A0100 train in the section of <6>.

In the system of the movement occlusion method of FIG. 6, since the distance that the train can move is up to the preceding train <8> position + safety distance <9>, the virtual course system 30 does not set the path in units of tracks, and Set a continuous virtual course for each section from the current position <7> and <10> to the safety distance <9> of the preceding train <8>.

FIG. 7 shows a description of a method of correcting a train position and a train number when the train occupancy information error occurs.

For example, if the occupancy information of a train operating at location <11> cannot be expressed due to a communication error during operation in section <12>, and the train occupancy information appears at location <13>, the virtual career system 30 Confirm that the train occupancy information at location <13> is continuous information by train operation, and move the train number remaining at location <11>, which is the target of the virtual path, to location <14>.

The virtual course system 30 recombines the train location and the train number, and then releases the virtual course of the remaining section at the back of the train running direction.

In the mobile occlusion method in which the train number (train unique number) and the location information of the train are received, the train schedule and the train number of the received train information are combined and managed. If you do not receive the information and receive the track occupancy information by Excel counter information after a certain time or area, <17> correct the location of the train number using the information of the virtual route set in the area, <15 > Clear the virtual route in the area before the train operation.

As shown in FIG. 8, in the existing CTC control system, the information received from the on-site interlocking device is judged, and in the case of the route information, the route related to the arrival and departure of the on-site station is set / released (S101 to S106), and the track is occupied. / It is configured to track the train number according to the unoccupied information (S107, S108).

Because it is difficult to track the train number when the train occupancy information is poor for the tracks between the train station and the station, rather than where the train number is tracked by the route to or from the on-site station, congestion occurs in the control service and train delay and This is because customer service is disrupted, causing complaints.

The virtual career system 30 is an auxiliary system for stable tracking of train numbers generated in a section between a station and a station in the CTC control system, and supports functional elements of the CTC server and control service.

As illustrated in FIG. 9, the route information and the track information received from the on-site interlocking device to the CTC control system are transmitted to the virtual route system 30 including the related train number.

As shown in FIGS. 9 and 10, the virtual career system 30 that has received the career information and the track information determines the career information and the track information again, and in the case of a career departing from the on-site station of the course information, to the next station The virtual path is set, and the setting information of the virtual path is transmitted to the CTC control system (S203 to S212) (S301 to S305).

Stores the location of the train number included in the track information, generates movement information of the train number according to the virtual path according to the track occupancy information, synchronizes it with the CTC control system, and releases the virtual path according to the track non-occupancy information. To the CTC control system.

According to the non-occupied information among the track information, if the train leaves the virtual path area where the train is running, the virtual path is dismissed and the information is transmitted to the CTC control system, and then additional virtual path is set in the direction of the train. It is determined and set if an unset virtual path is found (S306, S307).

In the process by the track occupancy information, the continuity of the track is determined (S308), and if the previous track is discontinuous information that is not occupied, the train position correction is determined to move the train number (S309, S310).

In case of continuous track occupancy information, the train number is moved from the beginning to the end of the virtual route currently located.

In the case of information related to the arrival route of the corresponding station among the route information, the virtual route system 30 does not process it, and in the case of the setting information of the departure route, successive virtual routes in the direction of the route (train) are set.

When a continuous train is established while a preceding train is running or an arrival route of the next station is found, the process of setting the virtual route is completed and information of the set virtual routes is transmitted to the CTC control system.

Because, if the virtual route is set by the arrival route rather than the departure route, it is duplicated with the actual departure route of the corresponding station, causing errors in CTC system train number movement and location tracking. This is because if two or more train numbers are duplicated due to the occupancy information of one train with the double virtual path setting at the station and the station, the error may occur.

In addition, if the train number movement is processed without determining the continuity of the track occupancy information, the train number is shifted to the location where the track occupancy misinformation occurs because the train number is moved due to misinformation in the field equipment and track occupancy data. Occurs.

The virtual career system that is additionally installed in the existing CTC control system does not install additional facilities in the field facilities, and transmits track information, course information, and train number information generated in the CTC control system to the virtual career system without installing additional facilities in the field facilities. As such, no additional field equipment is required.

Table 1 shows the basic information of the virtual career system.

As shown in Table 1, the virtual career system has basic information on the track and left / right connection information between tracks for judging the preceding train, basic information on the track, and left / right connection information between tracks for establishing a continuous connection path, train Has location information of train start / end train numbers to move the train number when entering the virtual path.

It analyzes and processes the route and track information received from the field and the basic information of the virtual route system, and provides the current train position information, virtual route information, and corrected train number position information to the CTC control system.

The train number is managed by connecting the train information and location information transmitted from the train to the train schedule, and when the communication with the train is interrupted, the train number location is analyzed and processed by analyzing the train number mapping information and the Excel counter reception information and related virtual path. After correction, it is provided to the CTC control system.

The CTC control system can selectively express (display / disable) whether or not the virtual path received from the virtual path system is displayed, and synchronize the corrected train number location information with the track occupancy information.

Difference from existing system

The CTC control system is configured to control train operation by using the track information and track setting information of the on-site facilities, and use the train number information in the control system to provide information on the train destination required by the customer. have.

According to the mixed-signal system mixed operation, if the track occupancy information is not received due to a certain time or a certain section of the track information in the field, an error occurs in the train number and train location information managed by the control system and control train operation. And a recovery time of a certain time or more is required in the system for providing information on the destination information of the customer train.

In recent years, when there is a delay in train operation, it is often the case that a customer who boards the train pays the economic cost of the train delay operation.

       Table 2 is a table showing the difference between the old and new systems in case of system failure.

If there is no virtual career system as shown in Table 2, the existing system needs a certain amount of time to recover from failure, and during the time of failure, continuous control tasks such as control of train operation and transmission of train destination information are impossible.

The virtual career system according to the present invention prepares for the failure of the existing CTC control system train number tracking function, shortens the time for normalizing the control task, minimizes train delay due to failure, and ensures the continuity of the controller's control task, Improve customer service satisfaction.
