  For example, when it is desired to increase the number of trains, it is considered that a section (hereinafter referred to as “protection section”) to be secured for positioning one train in order to reduce the train interval is made as narrow as possible.

  The guard section made using the track circuit has a fixed length regardless of the train length. Therefore, only one train can enter the protection section to which one train belongs, and the density of the train in a certain section is fixed by the track circuit. For this reason, if it is going to raise the density of a train in a certain area, the fixed length of a track circuit will be made small.

  However, if the fixed length of the track circuit is reduced to narrow the protective section, it takes a lot of time and effort. In addition, since the number of track circuits increases, there is a problem that maintenance costs become very large.

In addition, when trying to narrow the protection section using GPS, GPS cannot be used in the tunnel, and only part of the information necessary for detecting the train position can be obtained only by the position information obtained from GPS. Furthermore, since position information obtained using GPS does not take into account knitting growth, it is difficult to drive trains with different knitting growth on the same route.
In one aspect, the present invention aims to increase the density of trains that can be placed within a section.

  In order to achieve the above object, a disclosed information processing apparatus is provided. This information processing apparatus has a reception unit, an extraction unit, and a notification unit.

  The receiving unit receives position information including the position of the last vehicle of each of the plurality of trains operating on the track from each train. The extraction unit extracts a preceding train preceding each train on the track using the position information received by the reception unit. The notification unit notifies the subsequent train of each train of the position of the last train of the preceding train of each train extracted by the extraction unit.

  In one mode, the density of trains that can be arranged in a certain section can be increased.

Hereinafter, an information processing system according to an embodiment will be described in detail with reference to the drawings.
<Embodiment>
FIG. 1 is a diagram illustrating an information processing system according to an embodiment.

The information processing system 1 according to the embodiment includes lines 2a and 2b, signs 3a1 to 3a6, signs 3b1 to 3b6, and a central processing unit (information processing apparatus) 4.
FIG. 1 shows two lines 2a and 2b. The line 2a is a down line (down line), and the line 2b is an up line (up line).
The signs 3a1 to 3a6 are respectively arranged in the vicinity of the line 2a. The signs 3b1 to 3b6 are respectively arranged in the vicinity of the line 2b.

  The signs 3a1 to 3a5 are provided at intervals of 50 m (fixed intervals) on one side along the line 2a. Further, the distance between the sign 3a4 and the sign 3a6 is 50 m. The signs 3b1 to 3b5 are provided at intervals of 50 m on one side along the line 2b. Further, the interval between the marker 3b4 and the marker 3b6 is 50 m. The signs 3a1 to 3a6 and the signs 3b1 to 3b6 are installed, for example, on an overhead pole.

  Bar codes are described on the labels 3a1 to 3a6 and the labels 3b1 to 3b6. In the bar code, position identification information for identifying a position from the starting point (for example, about a kilometer, a driving line, a number line, etc.) is embedded. In FIG. 1, for the convenience of explanation, the signs 3a1 to 3a6 and the signs 3b1 to 3b6 show information indicating the distance from the starting point and information indicating the operation line instead of the barcode. “D” and “D” mean the down line. “D sub” means a down main line. “U” and “U” mean the main line. “U sub” means an up sub main line. For example, the train 5a shown in FIG. 1 shows a state in which the train 5a enters the descending sub-main line of the XX station from the descending main line. The train 5b shows a state of entering the up main line from the up sub main line of the XX station.

Cameras 6a and 6b are provided on the leading vehicle 5a1 and the last vehicle 5a2 of the train 5a traveling on the track 2a, respectively. Cameras 6c and 6d are provided on the leading vehicle 5b1 and the last vehicle 5b2 of the train 5b traveling on the track 2b, respectively. For example, the cameras 6a and 6b capture the barcodes described on the signs 3a1 to 3a6. Images taken by the cameras 6a and 6b are sent to the control device 7a that is provided in the train 5a and controls the operation of the train. Images captured by the cameras 6c and 6d are sent to the control device 7b that is provided in the train 5b and controls the operation of the train. Since the functions of the control device 7a and the control device 7b are the same, the function of the control device 7a will be described below representatively.
FIG. 2 is a block diagram illustrating functions of the control device.
The control device 7a includes an analysis unit 71, a storage unit 72, an information creation unit 73, a reception unit 74, and a display unit 75.

  The analysis unit 71 analyzes the images captured by the cameras 6a and 6b to read the content of the captured barcode. For example, in the example illustrated in FIG. 1, the analysis unit 71 reads the “3k100 m downlink secondary line” described in the sign 3a6 by analyzing the image captured by the camera 6a. The analysis unit 71 analyzes the image captured by the camera 6b to read “3k000m down main line” described in the sign 3a3. That is, the train 5a is located between 3k000m and 3k100m on the down line. The leading vehicle 5a1 of the train 5a is located on the secondary main line. Therefore, the protection section of the train 5a is between the descending main line 3k000m and the descending secondary line 3k100m. By adjusting the intervals at which the signs 3a1 to 3a6 are installed, the protection section can be easily adjusted.

Although not shown in FIG. 2, the analysis unit included in the control device 7b reads the “2k900m up main line” described in the sign 3b1 by analyzing the image captured by the camera 6c. Further, the analysis unit 71 reads the “3k100 m ascending secondary line” described in the sign 3b6 by analyzing the image captured by the camera 6d. That is, the train 5b is located between 2k900m and 3k100m on the up line. The leading vehicle 5b1 of the train 5b is located on the main line. Therefore, the protection section of the train 5b is between the upstream main line 2k900m and the upstream secondary line 3k100m.
The storage unit 72 includes, for example, a RAM (Random Access Memory).
For example, the train ID “C” of the train 5a received from the central processing unit 4 when the control device 7a is activated is stored in the storage area 72a of the storage unit 72.

  The analysis unit 71 analyzes the images captured by the cameras 6a and 6b to read the content of the captured barcode. The analysis unit 71 writes (overwrites) the read information in a predetermined storage area of the storage unit 72 every time the content of the captured barcode is read. More specifically, when the analysis unit 71 reads the information described on the sign by analyzing the image captured by the camera 6a, the analysis unit 71 writes the operation line in the storage area 72b among the read information. The read time is written in the storage area 72c. The position included in the read information is written in the storage area 72d. Hereinafter, the position included in the information read by analyzing the image captured by the camera installed in the head vehicle of the train is referred to as “the head position of the protection section”.

  Moreover, if the analysis part 71 reads the information described in the sign by analyzing the image imaged with the camera 6b, it will write the driving line contained in the read information in the memory area 72b. The read time is written in the storage area 72e. The position included in the read information is written in the storage area 72f. Hereinafter, the position included in the information read by analyzing the image captured by the camera installed in the last vehicle of the train is referred to as “the last position of the protection section”.

The information creation unit 73 creates train position information D1 indicating the position of the train 5a at the timing when the storage areas 72b to 72f of the storage unit 72 are updated. The train position information D1 includes the train ID, operation line, and time of the train 5a stored in the storage unit 72. Here, the time is the latest time in the storage areas 72c and 72e. The train position information D1 includes one or both of the head position of the guard section and the tail position of the guard section. Specifically, when the head position of the protection section stored in the storage area 72d and the last position of the protection section stored in the storage area 72f are updated at substantially the same timing, the information creation unit 73 is updated. Train position information D1 including both the head position of the guard section and the tail position of the guard section is created. When one of the head position of the guard section stored in the storage area 72d and the tail position of the guard section stored in the memory area 72f is updated, the head position of the updated guard section or the tail position of the guard section is updated. Train position information D1 including the position is created.
The information creation unit 73 transmits the created train position information D1 to the central processing unit 4 via train radio.

In addition, when the information creation unit 73 creates the train position information D1 including the head position of the protection section, the information creation unit 73 acquires a brake pattern from the central processing unit 4 that decelerates so that the train 5a does not collide with the preceding train of the train 5a. A brake pattern notification request is transmitted to the central processing unit 4.
Hereinafter, the process which the control apparatus 7a performs between the central processing units 4 with transmission of the train position information D1 is demonstrated.

  FIG. 3 is a sequence diagram for explaining processing performed by the control device with the central processing unit in accordance with transmission of train position information.

[Sequence Seq1] When the information creation unit 73 creates the train position information D1, the information creation unit 73 transmits the created train position information to the central processing unit 4.
[Sequence Seq2] The central processing unit 4 that has received the train position information transmits a train position information reception response indicating that the train position information has been received to the control device 7a.
[Sequence Seq3] The information creation unit 73 transmits a brake pattern notification request to the central processing unit 4 when the train position information D1 including the head position of the protection section is created.
[Sequence Seq4] Upon receiving the brake pattern notification request, the central processing unit 4 generates a brake pattern and transmits it to the control device 7a.
[Sequence Seq5] The control device 7a that has received the brake pattern transmits to the central processing unit 4 a brake pattern receipt response indicating that the brake pattern has been received.
This is the end of the description of the processing illustrated in FIG.

  In addition, when the train position information D1 including the tail position of the protection section is created, the information creating unit 73 executes the processes of the sequences Seq1 and Seq2 described above, and does not execute the processes of the sequences Seq3 to Seq5. As described above, the information creation unit 73 transmits a brake pattern notification request to the central processing unit 4 only when the barcode of the image captured by the camera 6a installed in the leading vehicle of the train 5a is successfully read.

  The central processing unit 4 collects train position information sent from the control devices 7a and 7b. And the central processing unit 4 transmits the preceding train information which shows the rear position of the train preceding the trains 5a and 5b to the control devices 7a and 7b via the train radio using the collected train position information. At this time, the train position information of each train may be included in the preceding train information and transmitted.

  The receiving unit 74 receives preceding train information transmitted by the central processing unit 4 along with transmission of train position information. The receiving unit 74 writes the received preceding train information in the storage areas 72g, 72h, 72i provided in the storage unit 72.

  In the storage area 72g, the train ID of the preceding train is written. The time when the preceding train information is received is written in the storage area 72h. In the storage area 72i, the last position of the protection section of the preceding train is written.

  The receiving unit 74 receives a brake pattern transmitted from the central processing unit 4. The receiving unit 74 writes the received preceding train information in the storage area 72j provided in the storage unit 72.

The display part 75 produces | generates the linear figure which a driver uses for a driving | operation using the information memorize | stored in the memory area 72g, 72h, 72i. The display unit 75 displays the brake pattern and the generated linear diagram on the monitor 8 connected to the control device 7a. The driver of the train 5a drives the train based on the brake pattern displayed on the monitor 8 and the linear diagram.

FIG. 6 is a diagram illustrating an example of information stored in the storage unit.

Information is tabulated and stored in the storage unit 4c. Train position information is stored in the table T1 shown in FIG. The table T1 is provided with columns of ID, operation track, time, front, rear, and preceding. Information arranged in the horizontal direction is associated with each other.

  The transmission unit 4d refers to the table T1. And the transmission part 4d transmits the preceding train information including the last position of the protection zone of the preceding train described in the preceding column to each train having the train ID described in the ID column.

Upon receiving the brake pattern notification request from the reception unit 4a, the generation unit 4e generates a brake pattern. Specifically, the generation unit 4e refers to the table T1. And the production | generation part 4e reads train ID contained in a brake pattern notification request. And the production | generation part 4e is about the protection area of the preceding train described in the preceding column from the head position of the protection area described in the front part about the record in which the train ID corresponding to the read train ID is described. A brake pattern that stops at the end position is generated. And the production | generation part 4e transmits the produced | generated brake pattern to the train with train ID contained in a brake pattern notification request.
Next, processing of the central processing unit will be described using a flowchart.
FIG. 7 is a flowchart showing the processing of the central processing unit.

  [Step S1] The receiving unit 4a determines whether train position information has been received. When train position information is received (Yes in step S1), the process proceeds to step S2. When the train position information is not received (No in step S1), the reception of the train position information is waited.

  [Step S2] The extraction unit 4b determines whether the train position information received by the reception unit 4a includes the head position of the protection section. If the train position information includes the head position of the protection section (Yes in step S2), the process proceeds to step S3. When the train position information does not include the head position of the protection section (No in step S2), the process proceeds to step S4.

  [Step S3] The extraction unit 4b describes the start position of the protection section included in the received train position information in the front column of the table T1. Thereafter, the process proceeds to step S4.

  [Step S4] The extraction unit 4b determines whether or not the train position information received by the reception unit 4a includes the last position of the protection section. When the train position information includes the last position of the protection section (Yes in step S4), the process proceeds to step S5.

  [Step S6] The extraction unit 4b extracts the last position of the preceding train of each train using the method described above, and describes it in the preceding column of the table T1. Then, the process proceeds to step S7.

  [Step S7] The transmission unit 4d refers to the table T1, and includes preceding train information including the last position of the protection section of the preceding train described in the preceding column for each train having the train ID described in the ID column. Send. Then, the process of FIG. 7 is complete | finished.

Note that the processing order is not limited to the order shown in FIG. For example, the processes of step S2 and step S3 may be performed after the processes of step S4 and step S5 are performed.
Next, a specific example of processing of the information processing system 1 will be described.
FIG. 8 is a diagram illustrating an example of processing of the information processing system.

  In FIG. 8, as an example, the distance from the starting point is shown as a relative value. Numerical values 1 to 29 shown below the line 2c are numerical values obtained by relativizing position information obtained by the signs. Each time 50m away from the starting point, the value increases by one. For example, “1” indicates a 50 m point from the starting point, and “2” indicates a 100 m point from the starting point.

  On the track 2c, trains 5c, 5d, and 5e, to which a plurality of vehicles are connected, operate. The train position information D2 is information created by the control device provided in the train 5c. The train position information D3 is information created by the control device included in the train 5d. The train position information D4 is information created by the control device included in the train 5e.

In the case of the example shown in FIG. 8, the head position of the guard section of the train 5c is “5”, the tail position is “2”, the head position of the guard section of the train 5d is “16”, the tail position is “13”, The head position of the protection section of the train 5e is “29”, and the last position is “26”.
The extraction unit 4b creates a table T1 in which train position information sent from each control device included in all the trains 5c to 5e existing on the track 2c is collected.

  The extraction part 4b calculates | requires the order of a train based on train position information D2-D4. And the extraction part 4b extracts the last position of the protection area of each preceding train of each train 5c-5e using the collected train position information, and describes it in the preceding column of table T1.

The transmission unit 4d refers to the table T1. And the transmission part 4d produces the preceding train information including the last position of the protection section of the preceding train described in the preceding column of the train ID of each of the trains 5c and 5d having the train ID described in the ID column. To do.
The transmission unit 4d transmits the created preceding train information to the control devices included in the trains 5c and 5d via train radio.

  The control devices included in each of the trains 5c and 5d that have received the preceding train information generate a linear diagram that the driver uses for operation based on the received preceding train information. Further, the control device displays the brake pattern and the generated linear diagram on a monitor connected to the control device. The driver drives the train based on the brake pattern displayed on the monitor and the linear diagram.

  In the example shown in FIG. 8, it is possible to easily grasp that the train 5d, which is a train subsequent to the train 5e, can approach to the position immediately before the last position “26” of the protection section of the train 5e. Since the sign installation interval is 50 m, for example, when the train 5 e stops for some reason, the train 5 d can stop within 50 m from the last vehicle of the train 5 e.

Moreover, the production | generation part 4e will produce | generate a brake pattern, if the brake pattern notification request | requirement is received from the receiving part 4a. And the production | generation part 4e transmits the produced | generated brake pattern to the train with train ID contained in a brake pattern notification request.
The trains 5c to 5e operate according to the brake pattern received from the central processing unit 4.

  FIG. 9 is a diagram for explaining operation by a brake pattern. Hereinafter, in FIGS. 9 to 11, illustration of a part of the information of the table T1 and the train position information D2 to D4 is omitted for the sake of space.

  FIG. 9A shows a brake pattern BP1 of the train 5d. Based on the brake pattern notification request transmitted by the control device of the train 5d, the generation unit 4e brakes from the start position “16” of the current protection section of the train 5d to the last position “26” of the current protection section of the train 5e. A pattern BP1 is created and transmitted to the control device of the train 5d.

  The brake pattern BP1 may be a multiple display system or a one-stage brake system. Hereinafter, the brake pattern of the one-stage brake system will be described as a representative. The control device for the train 5d that has received the brake pattern operates following the received brake pattern BP1. The control device sequentially compares the actual speed and the brake pattern BP1, and when the brake pattern BP1 is exceeded, the control device automatically decelerates to a speed that fits in the brake pattern BP1.

FIG. 9B shows a case where the analysis unit included in the control device of the train 5d succeeds in reading the position “17” from the image captured by the camera set in the leading vehicle of the train 5d. In this case, the generation unit 4e that has received the brake pattern notification request, based on the received preceding train information, from the start position “17” of the current protection section of the train 5d to the last position “26” of the current protection section of the train 5e. The brake pattern BP2 up to is created. Then, the control device operates following the created brake pattern. The control device sequentially compares the actual speed and the brake pattern BP2, and when the brake pattern is exceeded, the control device automatically decelerates to a speed that fits in the brake pattern BP2.
In the present embodiment, an example in which the central processing unit 4 creates a brake pattern is shown, but a control unit may create it.

  As described above, according to the central processing unit 4, the position of the last vehicle in the protection section of the preceding train is detected and notified to the following train. Therefore, the succeeding train can easily grasp the position of the last vehicle of the preceding train. For this reason, when it is desired to increase the number of trains, the distance from the preceding train can be reduced so as not to collide with the preceding train. Therefore, the density of trains that can be arranged within a certain section can be increased.

  In addition, a sign with a barcode attached was installed near the track, and the position of the last vehicle on each train was detected using a camera. Thereby, the position of the last vehicle can be detected easily. In addition, the position of the last vehicle can be detected at a lower cost than when the position of the train is detected using a track circuit.

In addition, the position of the first vehicle and the position of the last vehicle of each train is detected at two places (a plurality of places) of the first vehicle and the last vehicle of the train. Thereby, train growth and separation / merging of trains can be easily grasped.
Moreover, a protection area can be easily adjusted by adjusting the installation space | interval of label | marker 3a1-3a6, 3b1-3b6.

  For example, when the position of a train is detected using GPS, there is a problem that GPS cannot be used in a tunnel, and there is a position detection error due to a difference in height of a track. According to the information processing system 1, since the position identification information is acquired through train radio, the position in the tunnel can be identified. In addition, since the barcode with the actual position set is read, position detection errors can be suppressed.

  In addition, when the position of a train is detected using GPS, there is a problem that it is difficult to determine where the line is located in a section where the track is adjacent, such as in a train station or a vehicle station. According to the information processing system 1, since a barcode in which information such as a travel line and a number line is set is read, erroneous detection of the travel line and the number line can be suppressed.

  Moreover, when detecting the position of a train using GPS, there exists a problem that it is difficult to discriminate train knitting growth. For example, when inputting train knitting growth manually, there is a possibility of erroneous input of knitting growth. Furthermore, it may be difficult to detect the position of a train using GPS for a train having a different length, such as a freight train. According to the information processing system 1, since the positions of the leading and trailing vehicles of the train are detected using the cameras installed on the leading and trailing vehicles of the train, it is possible to easily determine the train growth of the train. it can. Therefore, for example, even when trains with different knitting growth are operated on the same route, the protection section can be easily grasped. Moreover, according to the information processing system 1, it can be easily detected that the distance between the leading vehicle and the last vehicle is a certain distance or more. Therefore, for example, it is possible to detect a case where the train separation of a running train occurs.

  In the present embodiment, the position of each vehicle on the train is detected using a camera. However, the present invention is not limited to this, and the position of each vehicle in the train may be detected using a transponder.

Moreover, in this Embodiment, the control apparatus with which each train is provided transmitted the train position information created to the central processing unit 4 whenever the train position information was created. However, the present invention is not limited to this, and the control device provided in each train synchronizes the time at which the train position information is transmitted, and each train transmits the train position information to the central processing unit 4 at the same time. Also good.
<Modification>

  By the way, there are cases where the barcode reading fails for some reason, such as when the camera fails to capture the barcode. Hereinafter, the operation of the train when barcode reading fails will be described.

  FIG. 10 is a diagram for explaining the operation of the train when reading the barcode of the image captured by the camera installed in the rear vehicle fails. In FIG. 10, it is assumed that the train 5e is stopped.

  FIG. 10A shows a case where the camera installed in the last vehicle of the train 5d fails to capture “14” after the train 5d transmits the train position information D3a to the central processing unit 4. In this case, the head position of the protection section stored in the storage unit of the control device included in the train 5d is “17”, and the last position is “13”. Although the guard section becomes longer on the rear side (left side in FIG. 10), it is safe because the following train does not collide.

  FIG. 10B shows a case where the camera installed in the leading vehicle of the train 5d succeeds in capturing “18” after the state shown in FIG. In this case, the control device of the train 5d transmits the train position information D3b to the central processing device 4. And if the extraction part 4b updates the front column of the table T1 from "17" to "18" based on the train position information D3b, the production | generation part 4e will train 5e from the head position "18" of the protection area of the train 5d. The brake pattern BP3 up to the last position “26” of the protection zone is created.

  FIG. 11 is a diagram for explaining the operation of the train when reading the barcode of the image captured by the camera installed in the leading vehicle fails. In FIG. 11, it is assumed that the train 5e is stopped.

  FIG. 11A shows a case where the camera installed in the head vehicle of the train 5d fails to capture “17” after the train 5d transmits the train position information D3c to the central processing unit 4. The head position of the actual protection section of the train 5d is “17”, and the last position is “14”. Here, the actual start position of the protection section is different from the start position of the protection section stored in the storage unit of the control device. However, since the head position of the protection section stored in the storage area of the storage unit is not updated, the control device for the train 5d does not transmit a brake pattern notification request to the central processing unit 4. At this time, the train 5d operates based on the brake pattern BP4 from the head position “16” of the guard section of the train 5d to the tail position “26” of the guard section of the train 5e. For this reason, the train 5d does not collide with the train 5e.

  FIG. 11B shows a case where the camera installed in the leading vehicle of the train 5d fails to capture “17”, “18”, “19”, and “20”. Note that the seconds of the time in the train position information in FIGS. 11B and 11C are omitted for the sake of space.

  The head position of the actual protection section of the train 5d is “20”, and the last position is “17”. Here, the actual start position of the protection section is different from the start position of the protection section stored in the storage unit of the control device. However, since the head position of the protection section stored in the storage area of the storage unit is not updated, the control device for the train 5d does not transmit a brake pattern notification request to the central processing unit 4. For this reason, the train 5d operates based on the brake pattern BP4. For this reason, the train 5d does not collide with the train 5e. The preceding train information received last by the train 5c is associated with transmission of the train position information D3d. This train position information D3d has been successfully read from the camera “17” installed in the last vehicle of the train 5d, and the train 5d is controlled as the position identification information stored in the storage area of the storage unit is updated. Information transmitted by the device. For this reason, the train 5c can grasp the exact rearmost position of the train 5d. Further, the extraction unit 4b updates the column at the rear of the table T1 to “17” based on the train position information D3d. The generation unit 4e creates a brake pattern BP5 from the head position “13” of the guard section of the train 5d to the tail position “17” of the guard section of the train 5d, and transmits the brake pattern BP5 to the control device included in the train 5c. The train 5c operates based on the brake pattern BP5. For this reason, the train 5c does not collide with the train 5d.

  FIG. 11C illustrates a case where the camera installed in the leading vehicle of the train 5d has successfully captured “21”. In this case, the head position of the actual protection section of the train 5d is “21”, and the last position is “17”. The information creation unit provided in the control device of the train 5d transmits the train position information D3e to the central processing device 4. In addition, the information creation unit of the train 5d transmits a brake pattern notification request to the central processing unit 4. Thereafter, the train 5d receives the brake pattern BP6 from the head position “21” of the current protection section of the train 5d to the tail position “26” of the current protection section of the train 5e.

  Moreover, the case where the camera installed in the head vehicle of the train 5c succeeds in capturing “14” is shown. In this case, the head position of the actual protection section of the train 5d is “14” and the last position is “10”. The information creation unit provided in the control device of the train 5c transmits the train position information D2b to the central processing device 4. In addition, the information creation unit of the train 5 c transmits a brake pattern notification request to the central processing unit 4. Thereafter, the train 5c receives the brake pattern BP7 from the start position “14” of the current protection section of the train 5c to the last position “17” of the current protection section of the train 5d.
