Description

RBC DEVICE {RADIO BLOCK CENTER APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an RBC (Radio Block Center), which is one of the ground installations according to European Railway Traffic Management System (ERTMS) / European Train Control System (ETCS).

One of the ground facilities according to ERTMS / ETCS, the RBC device is arranged in the train path and transmits the operation control signal to the train to control the operation of the train moving on the train path.

The RBC apparatus generates control data for controlling the operation of the train based on external data provided from the train or the control room.

However, if the RBC device transmits control data including an error to a train or a control room due to malfunction or data error, it may result in personal injury or property damage. Accordingly, in order to improve the reliability of the RBC apparatus, a structure in which data processing for the same external data is performed in duplicate has been proposed.

Conventional RBC devices for performing data processing in duplicate include first and second data processing means for generating first and second control data by receiving, sorting and processing external data, and first and second data processing means for generating first and second control data, And output means for outputting the final data according to whether or not the data is the same.

However, the first and second data processing means may have mutually different device characteristics. Therefore, the processing time required from the time when the first data processing means receives the external data until the first control data is transmitted to the output means and the processing time from the time when the second data processing means receives the external data, To the output means may be different from each other.

In particular, the time at which the first and second data processing means receive the external data may be different, and in this case, the difference in the time required for arranging the external data to process the same external data may be further increased have.

Because of the difference in processing time between the first and second data processing means, the delay time until outputting the final data to the external data may be increased, and thus the response speed of the RBC apparatus is lowered.

The present invention provides an RBC apparatus capable of preventing a decrease in response speed while performing double data processing.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention which are not mentioned can be understood by the following description and more clearly understood by the embodiments of the present invention. It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

In order to solve such problems, an example of the present invention is an RBC apparatus disposed in a train path and connected to a control server and a train operation server, the RBC apparatus comprising: a plurality of external data A sink module for receiving the sorting data and for sorting the plurality of external data and outputting sorting data; a sort module for processing the sorting data according to a mode profile of the train path set by the control server, And a second data processing module for processing the sorting data according to a mode profile of the train path and generating second control data when the sorting data is inputted RBC device.

The RBC device further includes a control module for supplying input synchronization to the first and second data processing modules. In this case, the alignment data is input to the first and second data processing modules based on the input synchronization.

The RBC apparatus further includes a comparison module for transmitting the same final data as the first and second control data to the control server or the train operation server when the first and second control data are identical.

The RBC device as described above includes a sink module for sorting input data to generate sorting data, and first and second data processing modules for processing the sorting data received from the sink module to generate first and second control data . The RBC apparatus further includes an output module for outputting final data according to whether or not the first and second control data are the same.

As described above, the first and second control data are generated by performing the data processing for the same input data in a double manner through the first and second data processing modules, And outputs it as data. Due to this data duplication, the reliability of the RBC device can be improved.

Then, the alignment of the input data is performed by the sink module, and the first and second data processing modules only process the alignment data received from the sink module at the same time. The processing time until the first data processing module processes the alignment data and transfers the first control data to the output module and the second data processing module processes the alignment data and transmits the second control data to the output module Can be mutually similar.

As described above, the difference in the processing time between the first and second data processing modules can be minimized by the sink module, so that the degradation of the response speed due to the processing time difference can be prevented.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.

Hereinafter, an RBC apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, with reference to FIG. 1, a train system including an RBC apparatus will be described.

Figure 1 is an illustration of an example of ERTMS / ETCS.

As shown in FIG. 1, the ERTMS / ETCS (European Railway Traffic Management System) includes a control server 10 for monitoring and controlling the entire train operation, a plurality of RBCs A train 30 operated in the train path 20 under the control of the apparatus 100, the control server 10 and the RBC apparatus 100, and a plurality of balises 40 arranged in the train path 20 do.

The control server 10 transmits a mode profile corresponding to the driving rules of each train path 20 to the RBC device 100.

The control server 10 collects information on the status of each RBC device 100 or the status of each train 30 from a plurality of RBC devices 100 and monitors the train operation on the basis of the collected information. Can be controlled.

The plurality of RBC apparatuses 100 correspond to the plurality of regions 101 in which the train path 20 is divided. Each of these RBC devices 100 controls and monitors the operation of the train 30 located within the corresponding area 101.

The plurality of balises 40 are arranged to be spaced apart from each other on the train path 20 for detecting angular positions of the train path 20. Each of these balises 40 transmits a unique identification signal.

A train 30 traveling on a train path 20 includes a train operating server (not shown) for monitoring and controlling operations.

When the train 30 passes a position adjacent to each balis 40, the train operating server receives the identification signal of the balis. The train operation server can detect the position of the balis 40 corresponding to the received identification signal and detect the position of the train 30 corresponding to the time when the identification signal is received.

In this ERTMS / ETCS, the RBC device 100 is connected to the train server of the train 30 in operation in the control server 10 and the area 101. The RBC device 100 controls and monitors the operation of the train 30 according to the mode profile of the train path 20 set by the control server 10. [

That is, the RBC device 100 receives various external data from at least one of the control server 10 and the train operation server. The external data includes train identification data for identifying the train 30, train operation data corresponding to the operation of the train 30, train path data corresponding to the mode profile of the train path 20, The handover data corresponding to the handover between the train 20 and the train 30, and the failure data for the occurrence of the failure of the train 30 or the train 30. [

The RBC device 100 processes the external data according to the mode profile of the train path 20 to generate control data and transmits the control data to the control server 10 or the train operating server. Here, the control data includes at least one of the operation control data for controlling the operation of the train, the train state data corresponding to the running state of the train, and the RBC state data corresponding to the driving state of the RBC.

In particular, the RBC device 100 according to an embodiment of the present invention performs data processing in a dual way in processing control of external data and generating control data. With this, the reliability of the RBC device 100 can be improved.

Hereinafter, an RBC apparatus 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 8. FIG.

2 is a view illustrating an RBC apparatus according to an embodiment of the present invention. FIG. 3 is a view showing each module of the RBC apparatus of FIG. 2. FIG. 4 is a diagram illustrating a method of redundantly processing data by the RBC apparatus of FIG. 5 is an illustration of external data received during a predetermined processing reference period in the sink module of FIG. FIG. 6 is a diagram showing alignment data by the sync module of FIG. 3 in the example of FIG. 5;

2, the RBC apparatus 100 according to an exemplary embodiment of the present invention includes a sink module 110 for receiving a plurality of external data OD1, OD2, ODi, ODn and outputting alignment data AD, A first data processing module 121 for processing the sorting data AD in accordance with the mode profile of the train path to generate first control data CD1, a second data processing module 121 for processing the sorting data AD according to the mode profile of the train path, A second data processing module 122 for generating second control data CD2, a control module 122 for supplying input data for synchronizing input data to the first and second data processing modules 121 and 122, And a comparison module 140 for transmitting the final data FD to the control server 10 or the train operation server 31 according to whether or not the first control data 130 and the first and second control data CD1 and CD2 are the same do.

The sink module 110 receives a plurality of external data OD1 to ODn from at least one of the control server 10 and the train operation server 31. [ The sink module 110 aligns the plurality of received external data OD1 to ODn according to a predetermined criterion.

For example, the sink module 110 may sort the plurality of external data OD1 to ODn received during a predetermined processing reference period according to a predetermined criterion. At this time, the predetermined criterion may be the reception order of the plurality of external data OD1 to ODn. That is, the sink module 110 determines that the first external data among the plurality of external data OD1 through ODn is the highest among the plurality of external data (OD1 through ODn) (OD1 to ODn).

The sink module 110 sequentially transmits at least one of the plurality of sorted external data OD1 to ODn from the highest ranked external data to thereby transmit the sorted data AD.

The first data processing module 121 processes the sorting data AD according to the mode profile of the train path 20 to receive the first control data CD1 .

Here, the mode profile may be a regulation for controlling the operation of the train 30 via the area 101 corresponding to the RBC device 100 in the train path 20. [ For example, the mode profile includes a regulation for controlling the train 30 in an OS (On Sight) mode in which the train 30 is operated by manual operation of the driver in at least a part of the train path 20 included in the area 101 can do. Alternatively, the mode profile may include a regulation for controlling the train 30 in an FS (Full Supervision) mode operated by automatic operation of the train operation server 31 in at least some sections other than the other sections. Alternatively, the mode profile may include provisions that limit the speed of the train 30 in at least another period of time. However, this is merely an example of a mode profile, and it is natural that the mode profile can be modified to any extent as specified in ERTMS / ETCS.

The mode profile of the train path set in the first data processing module 121 may be created or modified based on the train path data among the external data provided by the control server 10 and transmitted through the sink module 110. [

The second data processing module 122 receives the sorting data AD of the sink module 110 and outputs sorting data AD according to the mode profile of the train path 20 in the same manner as the first data processing module 121. [ To generate second control data CD2.

At this time, the second data processing module 122 receives the same sorting data AD from the sink module 110 at the same time as the first data processing module 121. The first data processing module 121 processes the alignment data AD according to the same mode profile.

In order for the first and second data processing modules 121 and 122 to process the same alignment data AD at the same time point as described above, the alignment data AD of the sync module 110 is subjected to the first and second data processing It is necessary to fit the modules 121 and 122 to be input at the same time.

The control module 130 supplies an input synchronization signal IS for synchronizing synchronization of the alignment data AD of the sync module 110 to the first and second data processing modules 121 and 122.

That is, the sink module 110 may transmit the alignment data AD based on the input synchronization supplied from the control module 130. [

Since the first and second data processing modules 121 and 122 may have different data transmission and reception characteristics between the first and second data processing modules 121 and 122 and the sink module 110, ) To receive the sorting data. Thus, it is possible to prevent the time at which the alignment data AD is input to the first and second data processing modules 121 and 122 from being different due to the difference in data transmission / reception characteristics.

In this manner, the alignment data AD is input to the first and second data processing modules 121 and 122 based on the input sync IS. Therefore, the first and second control data CD1 and CD2 generated by the first and second data processing modules 121 and 122 are input to the first and second data processing modules 121 and 122 at the same time, Corresponding to the data.

The comparison module 140 delivers the final data according to whether or not the first and second control data CD1 and CD2 are the same.

That is, if the first and second control data CD1 and CD2 are the same, the comparison module 140 outputs the same final data as the first and second control data CD1 and CD2 to the control server 10 or the train operating server (31).

If at least one of the first and second data processing modules 121 and 122 is defective and at least one of the first and second data processing modules 121 and 122 is set to an improper mode profile , Even if the same alignment data AD is processed, the resulting first and second control data CD1 and CD2 can be derived differently.

At this time, since the first and second control data CD1 and CD2 are different from each other, the comparison module 140 does not output the first and second control data CD1 and CD2 as final data. As an example, the comparison module 140 may discard the first and second control data CD1, CD2.

As described above, since the processing of the alignment data AD according to the mode profile can be performed by the first and second data processing modules 121 and 122 twice, the reliability of the RBC device 100 can be improved .

The first and second data processing modules 121 and 122 receive and sort the external data ODi by the sync module 110 and the first and second data processing modules 121 and 122 receive the external data ODi from the sync module 110, Only processing is performed. Therefore, the processing speed difference between the first and second data processing modules 121 and 122 can be slightly reduced.

Therefore, since the processing time required to generate the first and second control data CD1 and CD2 becomes similar, the processing time difference becomes small. As a result, a decrease in the response speed due to the data double processing can be prevented.

3, in the RBC apparatus 100 according to an embodiment of the present invention, the sink module 110 includes a receiving unit 111, an aligning unit 112, and a sink output unit 113 ).

The reception unit 111 receives a plurality of external data ODi from the control server 10 or the train operation server 31. [ (S10 in Fig. 4)

The sorting unit 112 arranges a plurality of received external data ODi according to a predetermined criterion. Thus, alignment data AD composed of external data ODi rearranged in order is generated. (S20 in Fig. 4)

For example, the criterion for aligning the plurality of external data ODi may be the reception timing of each external data ODi.

5, during the predetermined processing reference period PRP, the first handover data OD_h1, the first train identification data OD_t1, the second train identification data OD_t2, the first train operation The order of the data OD_d1, the first train path data OD_c1, the second train driving data OD_d2, the third train driving data OD_d3, the first fault data OD_f1 and the fourth train driving data OD_d4 The receiving unit 111 first receives the signal from the receiving unit 111 as an example.

In the example of FIG. 5, when the external data ODi is aligned according to the reception time of each external data ODi, as shown in FIG. 6, , And the external data with a late reception timing is disposed at a lower rank.

That is, the first received first handover data OD_h1 becomes the highest rank (the lower rank of FIG. 6), and the lowest received fourth train driving data OD_d4 becomes the lowest rank (the upper end of FIG. 6) do.

3 and 4 will be described again.

The sync output unit 113 outputs the alignment data AD to the first and second data processing modules 121 and 122. At this time, the sync output unit 113 may output the alignment data AD based on the input sync (IS) of the control module 140.

Each of the first and second data processing modules 121 and 122 includes an input unit 201, a profile holding unit 202, a process execution unit 203, and a process output unit 204.

The input unit 201 of each of the first and second data processing modules 121 and 122 senses alignment data AD of the sink module 110 at a similar point in time. As an example, the input unit 201 may sense the alignment data AD based on the input sync (IS) of the control module 140. [ (S30 in Fig. 4)

The profile holding unit 202 holds the mode profile of the train path 20 set by the control server 10. In one example, the profile holding unit 202 may hold a data processing program according to the mode profile.

The processing execution unit 203 of the first and second data processing modules 121 and 122 performs processing of the alignment data AD based on the mode profile of the train path 20. The processing execution unit 203 of the first and second data processing modules 121 and 122 performs data processing independently of each other so that the first and second control data CD1 and CD2 are generated. (S40 in Fig. 4)

The processing output unit 204 outputs control data CD1 and CD2 by the processing execution unit 203. [

At this time, the output timing of the first and second control data may also be set to the same synchronism by the control of the control module 130. [ 3, the control module 130 may further supply an output synchronization for synchronizing output timing, and may be provided with a processing output unit 204 (not shown) of the first and second data processing modules 121 and 122, Can output the first and second control data CD1 and CD2 based on the output synchronization.

The comparison module 140 includes a comparison unit 141 and a transmission unit 142.

The comparator 141 generates the same final data FD as the first and second control data CD1 and CD2 when the first and second control data CD1 and CD2 are the same. (S50)

On the other hand, the comparator 141 can discard the first and second control data CD1 and CD2 when the first and second control data CD1 and CD2 are different. (S51)

The transmitting unit 142 transmits the final data FD to the control server 10 or the train operating server 31. [ (S60)

Meanwhile, the RBC apparatus 100 according to an embodiment of the present invention includes a first and a second data processing modules 121 and 122 that generate first and second control data CD1 and CD2 through data processing, And a sink module 110 for receiving and arranging external data ODi. This prevents the difference in the processing time required for generating the first and second control data CD1 and CD2 from increasing due to the time required for alignment of the external data ODi.

Therefore, according to the embodiment of the present invention, even if a plurality of external data ODi are aligned based on the priority of each external data ODi, it is necessary to generate the first and second control data CD1 and CD2 It is possible to prevent the response speed from being lowered due to the difference in the processing time.

FIG. 7 is a diagram illustrating modules of the RBC apparatus of FIG. 2 according to another embodiment of the present invention. FIG. 8 is a diagram showing an example of alignment data by the sink module of FIG. 7 in the example of FIG. 5;

That is, as shown in FIG. 7, the RBC apparatus 100 'according to another embodiment of the present invention includes a priority level reading unit 114', except that the sink module 110 ' 3, the description of the RBC apparatus 100 will be omitted.

7, the sink module 110 'according to another embodiment of the present invention includes a receiving unit 111, a priority reading unit 114, an aligning unit 112, and a sink output unit 113 .

The reception unit 111 receives a plurality of external data ODi from the control server 10 or the train operation server 31. [

The priority reading section 114 detects the priority of each of the plurality of external data ODi. Here, the priority order of each external data (ODi) can be set in advance by the control server (10).

As described above, a plurality of external data may include train identification data, train operation data, train path data, fault data, and handover data. In this case, it may be set to a lower priority in the order of failure data, train path data, train identification data, train operation data, and handover data in accordance with the occurrence of an accident, the variability, and the importance of monitoring. That is, the train path does not change frequently, but the fault data corresponding to the fault occurrence corresponds to an abrupt variable that can lead to an accident, so that the fault data can be set to a higher priority than the train path data. In this case, since the fault data can be processed first, the occurrence of the linkage due to the failure can be reduced.

However, this is merely an example, and it is a matter of course that the priority of the external data can be freely set according to the condition.

The alignment unit 112 'aligns the plurality of external data ODi based on at least one of the reception order of the external data ODi and the priority order of the external data ODi.

In other words, referring to the example of FIG. 5, as shown in FIG. 8, the aligner 112 'arranges the first fault data OD_f1 having the first priority at the first rank (the lowermost end in FIG. 8) The first train identification data OD_t1 and the second train identification data OD_t2 having the third priority are arranged in the order of reception, Are sequentially arranged in the third and fourth ranks. The first train operation data OD_d1, the second train operation data OD_d2 and the third train operation data OD_d3 having the fourth priority are sequentially placed in the fifth, sixth, and seventh ranks according to the reception order And places the first handover data OD_h1 having the last lowest priority in the eighth rank.

The sync output unit 113 outputs the alignment data AD to the first and second data processing modules 121 and 122.

As described above, according to another embodiment of the present invention, it is possible to arrange the processing order of the external data according to the priority order of the external data corresponding to the degree of importance such as accident-inducingness, volatility and monitoring importance, Can be prevented. Therefore, the reliability of the RBC device 100 'can be further improved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, But the present invention is not limited thereto.
