Description

  The present invention relates to a branching part presence line detection method and the like for detecting a standing line at a branching part.

  A train detection technique for determining whether a train exists on a track is known. The most common technique is a technique of providing train insulation and detecting a train by a track circuit. A branch portion that is a line section provided with a branching device (also referred to as a point) can also be configured as one track circuit (see, for example, Patent Document 1).

JP 2001-301618 A

  However, in order to reduce noise and vibration when the train passes through the branch part, and to reduce maintenance, train detection without rail insulation is required at the branch part.

  An uninsulated track circuit is known as a track circuit that does not use rail insulation, but there are some problems in application of the uninsulated track circuit to a branch portion. In the first place, if a technology capable of detecting a train at a branching portion without realizing an existing line detection mechanism such as a track circuit at the branching portion can be realized, a fundamental solution can be achieved.

  In addition, it is difficult to provide rail insulation for an integrated rail or the like of a branch part in a tram, and it can be a useful technique if train detection at a branch part is possible without providing an on-line detection mechanism at the branch part. .

  The present invention has been devised in view of the above circumstances.

The first invention for solving the above-described problems is
A branching unit that changes an opening direction between N lines (for example, the upward direction in FIGS. 1 and 6) and M lines (for example, the downward direction in FIGS. 1 and 6) by the switching operation of the switch. (E.g., branching section C1, C2 in FIGS. 1 and 6)
Adjacent section of the N lines with the branch section (hereinafter referred to as “N-side adjacent section”) (for example, the upstream adjacent section U1 in FIG. 1) and the adjacent section of the M lines with the branch section. (Hereinafter referred to as “M side adjacent section”) and (for example, the downward adjacent portion D1 in FIG. 1) are provided with a predetermined on-line detection mechanism for detecting the on-line of the train,
Using the presence detection result of the N side adjacent section, the presence detection result of the M side adjacent section, and the opening direction to determine whether or not the train is in the branching section;
This is a branch line presence detection method.

  According to the first aspect of the present invention, if the standing line detection mechanism is provided in the N side adjacent section and the M side adjacent section, a train is connected to the branching section using the standing line detection result and the opening direction of the branching section. It is possible to realize train detection as to whether or not there is a track. There is no need to provide an existing line detection mechanism at the branch portion.

More specifically, for example, the second invention is the first invention,
When it is determined that the branch portion is a non-existing line, if any of the N-side adjacent sections becomes an existing line, the adjacent section in the opening direction among the M-side adjacent sections becomes a non-existing line. Until it becomes a standing line, the determination process at the time of N side approach which judges the above-mentioned branching part as a standing line,
If any of the M side adjacent sections becomes a standing line when the branching portion is determined to be a non-existing line, the adjacent section in the opening direction of the N side adjacent sections becomes a standing line and is further non-existent. Until it becomes a standing line, a determination process at the time of M-side entry that determines the branching part as a standing line,
This is a branch line presence line detecting method for performing

  According to the second aspect of the invention, when any of the N side adjacent sections becomes a standing line when the branching section is not present, the train enters the branching section from the N side adjacent section, and further Travel to the M side adjacent section along the opening direction. For this reason, a branch part can be determined as a standing line until an adjacent section in the opening direction of the M-side neighboring sections becomes a standing line and further becomes a non-existing line. Similarly, when any of the M side adjacent sections becomes a standing line when the branching section is not present, the train enters the branching section from the M side adjacent section, and further N along the opening direction of the branching section. Drive to the side adjacent section. For this reason, a branch part can be determined to be a standing line until the neighboring section in the opening direction of the N-side neighboring sections becomes a standing line and further becomes a non-existing line.

As a further specific invention, the third invention is the second invention,
The branch portion has at least one direction of crossover, and the non-crossover course that does not travel on the crossover in a section where the N lines and the M lines are parallel, and travels on the crossover The direction of the crossing direction can be changed by the opening direction,
In the N-side entry determination process, when the opening direction is the non-crossing direction, the line portion to be connected in the branch portion corresponding to the adjacent section that is the existing line in the N-side adjacent section (For example, one of the sections XVT and YVT in FIG. 2) is determined as a standing line,
In the M-side entry determination process, when the opening direction is the non-crossing direction, the line portion to be connected in the branch portion corresponding to the adjacent section that is the existing line in the M-side adjacent section (For example, one of the sections XVT and YVT in FIG. 2) is determined to be a standing line.
This is a branch line presence detection method.

  According to the third aspect of the invention, the branching portion has at least one direction of crossover, and the non-crossover course that does not travel on the crossover in a section in which N lines and M lines are parallel. In addition, it has a structure in which the course in the crossing direction traveling on the crossover line can be changed depending on the opening direction. Therefore, in the N-side approach determination process, when the opening direction is a non-crossing direction, the line portion to be connected in the branching portion corresponding to the adjacent section that is the existing line in the N-side adjacent section is determined. It can be determined as a standing line. Moreover, in the determination process at the time of M side approach, when the opening direction is a non-crossing direction, the line part to connect among the branch parts corresponding to the adjacent section which became the standing line in the M side adjacent section is determined. It can be determined as a standing line.

In this case, as the fourth invention, in the third invention,
In the N-side entry determination process, when the opening direction is the crossing direction, both line parts connected to the crossover line (for example, both the section XVT and the section YVT in FIG. 2) are determined to be present lines,
In the M-side entry determination process, when the opening direction is the crossing direction, both line parts connected to the crossover line (for example, both the section XVT and the section YVT in FIG. 2) are determined as existing lines.
A branching part presence line detection method can be configured.

As a fifth invention,

  Hereinafter, an example of an embodiment to which the present invention is applied will be described. In the present embodiment, it is assumed that the train can travel on the same track in both the upper and lower directions. In addition, in order to make the explanation easy to understand, a maximum of two sets of parallel lines are used, and the branching portion is configured as a crossover line (first embodiment) and a one-way crossover line (second embodiment). Each embodiment will be described.

[First Embodiment]
First, the first embodiment will be described. The first embodiment is an embodiment in the case where the branch part C1 is a crossover line (also referred to as “Chisar crossing” or “double crossover line”), and FIG. 1 shows a line configuration before and after the branch part C1. . The branch part C1 is equipped with four switch machines 11 to 14, and two crossovers are overlapped in an X-shape between two parallel lines so that they can cross each other from both directions. Has been.

  The upstream adjacent portion U1 is an upstream line portion adjacent to the branch portion C1, and the downstream adjacent portion D1 is a downstream line portion adjacent to the branch portion C1. A predetermined on-line detection mechanism that detects the on-line of the train is provided in each section of the ascending adjacent portion U1 and the descending adjacent portion D1. The upper section in FIG. 1 of the upstream adjacent portion U1 is a section Y2T, and the lower section is a section X2T. Further, the upper section in FIG. 1 of the downward adjacent portion D1 is a section Y22T, and the lower section is a section X22T.

  As for the route passing through the branch part C1, the route XXL from the section X2T to the section X22T when the turning machine 11 is positioned as the opening direction, and the section X2T from the section X22T when the switching machine 13 is positioned as the opening direction. Route XXR to reach Y, route YYL from section Y2T to section Y22T when the turner 14 is in the opening direction, path YYR from section Y22T to section Y2T when the turner 12 is in the direction of opening The path YXL from the section X2T to the section Y22T when the switching machine 11 is in the reverse direction as the opening direction, the path YXR from the section Y22T to the section X2T when the switching machine 12 is in the reverse direction as the opening direction, the opening The direction XYL from the section Y2T to the section X22T when the turning machine 14 is upside down as the direction, and the section X2 when the turning machine 13 is upside down as the opening direction There is route XYR leading to interval Y2T from T.

  Which route is configured, that is, which conversion operation of the switching machines 11 to 14 is performed, the interlocking logic processing units 30A and 30B of the interlocking devices 10A and 10B (see FIGS. 3 and 4). ) Is determined and executed. After the conversion operation of the switch 11 to 14 is completed and the course is configured, the traffic signal is shown as a passage permission as a passage permission to the branch part C1 for the train. The display control of the traffic lights is also performed by the interlocking logic processing units 30A and 30B of the interlocking devices 10A and 10B.

  Now, as the route that passes through the branching section C1, either a route that passes through a connecting line between two parallel lines (hereinafter referred to as “crossing direction”) or two lines that do not pass through the connecting line and are parallel to each other can be used. There is a course (hereinafter referred to as “non-crossing direction”). In the case of crossover direction, the branch portion C1 is occupied by one train passing through the branch portion C1, and no other route can be formed. However, in the case of non-crossover direction, the route XXL or route XXR The route YYL or the route YYR can be configured at the same time.

  Therefore, in the present embodiment, as shown in FIG. 2, the section is divided at the center of the crossover portion in the branching section C1, and is called sections XVT and YVT, which are defined as virtual sections.

  3 and 4 are diagrams illustrating an example of the configuration of the interlocking devices 10A and 10B that implement the present embodiment. The interlocking device 10A in FIG. 3 and the interlocking device 10B in FIG. 4 are different depending on whether the function of the branch line presence detection unit 15 is performed by the interlocking logic processing unit 30A or the train detection unit 20B. Are the same.

  Both interlocking devices 10A and 10B provide a chain between a train, a traffic light, and a turnover depending on the train's travel route, existing line position, etc., and secure the course of the train so that each train travels safely. This is a signal security device. The interlocking devices 10A and 10B are roughly divided as functional units and include train detection units 20A and 20B and interlocking logic processing units 30A and 30B. Although not shown, the interlocking devices 10A and 10B include an interlocking control panel for inputting an instruction operation to the interlocking logic processing units 30A and 30B.

  The train detection units 20A and 20B are functional units that detect a train line for each section obtained by dividing the track into predetermined sections, and are based on a detection signal from a track detection mechanism provided in each section excluding the branch section C1. Then, the train presence in each section is detected. However, since the train detection unit 20B includes the branch line presence line detection unit 15, the train detection unit 20A can determine the train line presence in all sections including the branch part C1, whereas the train detection unit 20A includes the branch part presence line detection unit 15. Since it does not include, the train existing line of sections other than the branch part C1 is judged.

  The standing line detection mechanism may be, for example, a track circuit, or may be another detection mechanism such as a loop coil train detection device. Moreover, when it is set as a track circuit, it may be a commercial track circuit with rail insulation or an uninsulated track circuit without rail insulation. The train presence line results (whether they are present or not) detected by the train detection units 20A and 20B are input to the interlocking logic processing units 30A and 30B as needed.

  The interlocking logic processing units 30A and 30B are functional units that perform the main functions of the interlocking devices 10A and 10B, such as presence / absence of a train line in each section input from the train detection units 20A and 20B, traffic lights, switchboards, etc. Based on the status signal input from the field equipment, the state monitoring of each field equipment and the state transition instruction (operation instruction) are performed, and the switchover control of the branching section C1 for the course handling by the interlocking control panel is performed. It is responsible for all functions related to chaining, including path locking, signal control, etc. In addition, the interlocking logic processing unit 30A includes a branching portion presence line detection unit 15 that detects a train presence line of the branching portion C1.

  The branch part presence line detection unit 15 uses the presence detection result of the adjacent parts U1 and D1 adjacent to the branch part C1 and the opening direction of the branch part C1 to which section in the branch part C1 the train is present. It is a function part which determines. Since the branching portion presence line detection unit 15 can be regarded as a single device, the branching portion presence line detection unit 15 can be referred to as a branching portion presence line detection device. In this embodiment, the condition indicating the opening direction is described as using the switchover state (localization or inversion), but other conditions such as a path lock condition may be used, or the switchover may be switched. The state and other conditions may be combined.

  A specific operation of the branch line presence line detection unit 15 will be described with reference to FIG. FIG. 5 is a logic diagram showing a train detection operation at the branching section C1 by the branching section presence line detection section 15. The branch line presence line detection unit 15 can be realized using a relay circuit based on the logic diagram shown in FIG. 5 or an electronic logic circuit using a microcomputer.

  The branching portion presence line detection unit 15 becomes the opening direction of the downward adjacent portion D1 when any section of the upstream adjacent portion U1 becomes a standing line when the branching portion C1 is determined to be a non-existing line. The branch part C1 is determined to be a standing line until the section becomes a standing line and further becomes a non-present line. Further, when any section of the downward adjacent portion D1 becomes a standing line when the branching portion C1 is determined to be a non-existing line, a section in the opening direction of the upward adjacent portion U1 becomes a standing line. Further, a part or all of the branching part C1 is determined to be a standing line until it becomes a non-present line.

  More specifically, in this embodiment, the branch part C1 is a crossover line, and there are a non-crossing direction and a crossing direction as the opening direction. For this reason, when the opening direction is the non-crossing direction, a part of the branching portion C1 is set as the target of the standing line detection. When there is an approach from the ascending direction to the branching part C1, the train passes by connecting to each adjacent part according to the opening direction of the branching part C1 corresponding to the section where the existing line is located in the ascending neighboring part U1. The section to be determined is determined to be a standing line (upward approach determination process). On the contrary, when there is an approach from the downward direction to the branching portion C1, it is connected to each adjacent portion by the opening direction of the branching portion C1 corresponding to the section of the downward adjacent portion U1 that has been in the line. A section through which the train passes is determined to be a current line (determination process at the time of descending approach).

  For example, when the switch 11 is in the localization (non-crossing direction), the section XVT is in the non-existing state, and the existing line in the section X2T is detected, there is an approach from the upward direction to the section XVT. It can be determined that the vehicle travels to the section X22T. Therefore, the section X2T becomes a start line, and the section X22T in the non-crossing direction corresponding to the section X2T becomes a stay line and further becomes a non-existence line. Is detected.

  In addition, when the switch 13 is in a fixed position (non-crossing direction), the section XVT is in the non-existing state, and the standing line of the section X22T is detected, there is an approach from the downward direction to the section XVT. It can be determined that the vehicle travels to the section X2T. Therefore, the section X22T becomes a start line, and the section X2T in the non-crossing direction corresponding to the section X22T becomes a stay line and further becomes a non-existence line. Is detected.

  The description of the case where the presence line detection target is the section YVT is omitted, but the presence line of the section YVT can be detected by the logic shown in FIG. 5 similarly to the section XVT.

When the opening direction is the crossover direction, both sections (that is, the section XVT and the section YVT) connected to the crossover line of the branching section C1 are subject to the presence line detection.
For example, when the switch 11 is upside down (crossing direction), the section XVT and the section YVT of the branch section C1 are in the non-existing state, and the standing line of the section X2T is detected, the branch section C1 Therefore, it can be determined that there is an approach from the ascending direction and the vehicle travels to the section Y22T. Therefore, the section X2T is a start line, and the section Y22T in the crossing direction corresponding to the section X2T is a stay line and further a non-existence line. XVT and section YVT are detected as standing lines.

  In addition, when the turning machine 13 is in the inverted position (crossing direction), the section XVT and the section YVT of the branching section C1 are in the non-existing state, and the standing line of the section X22T is detected, the branching section C1 Therefore, it can be determined that there is an approach from a downward direction and the vehicle travels to the section Y2T. Therefore, the section X22T becomes a start line, and the section Y2T in the crossing direction corresponding to the section X22T becomes a stay line and further becomes a non-existence line. XVT and section YVT are detected as standing lines.

  Although the description when the train enters from the sections Y2T and Y22T is omitted, the presence lines of the section XVT and the section YVT of the branch part C1 are detected by the logic shown in FIG. 5 as in the case where the train enters from the sections X2T and X22T. Can do.

  As described above, according to the first embodiment, if a standing line detection mechanism is provided in the upstream adjacent part U1 and the downstream adjacent part D1 adjacent to the branch part C1, the presence line detection result and the branch part C1 Using the opening direction, it is possible to realize train detection as to whether or not a train is present at the branch part C1. There is no need to provide a standing line detection mechanism at the branch portion C1.

[Second Embodiment]
Next, a second embodiment will be described. The second embodiment is an embodiment in which the branch portion C1 of the first embodiment is a branch portion C2 having only a one-way crossover. As shown in FIG. 6, the branching section C2 is provided with only a crossover that connects the section Y2T of the upstream adjacent section U2 and the section X22T of the downstream adjacent section D2.

  However, the branch part C2 can take the crossing direction and the non-crossing direction as the opening direction as in the first embodiment. Therefore, as shown in FIG. 7, virtual sections XVT and YVT are set, and in the non-crossing direction, a part of the branching part C2 is set as the target of the line detection, and in the crossing direction, the crossing of the branching part C2 Train detection is performed using both sections connected to the line (that is, the section XVT and the section YVT) as the targets of the line detection.

The configuration of the interlocking devices 10A and 10B is the same as that of the first embodiment. However, the branch portion presence line detection unit 15 has different operation logic, as shown in FIG.
First, when the switch 13 is in the inverted position (crossing direction) and when the switch 14 is in the inverted position (transfer direction), it is the same as in the first embodiment.

  However, when the switch 13 is in a fixed position (non-crossing direction), the following occurs. That is, when the section XVT of the branch portion C2 is in the non-existing state and the presence line of the section X22T is detected, it can be determined that the branch portion C2 has entered from the downward direction and travels to the section X2T. Therefore, the section X22T becomes a start line, and the non-crossover section X2T corresponding to the section X22T becomes a stop line and further becomes a non-existence line. The section XVT is detected as a standing line.

Further, when the section XVT of the branch portion C2 is in the non-existing state and the presence line of the section X2T is detected, it can be determined that there is an approach from the upstream to the branch portion C2 and the vehicle travels to the section X22T. For this reason, the section X2T becomes a starting line, and the non-crossing section X22T corresponding to the section X2T becomes a standing line and further becomes a non-existing line. The section XVT is detected as a standing line.
The same applies to the case where the switch 14 is in the localization (non-crossing direction), and the presence line detection of the section YVT of the branching section C2 can be performed.

  As described above, according to the second embodiment, even in the branching section C2 in which the branching section is formed of a crossover in only one direction, the existing line is connected to the upstream adjacent section U2 and the downstream adjacent section D2 adjacent to the branching section C2. If the detection mechanism is provided, it is possible to realize train detection as to whether or not a train is present at the branch part C2 by using the presence line detection result and the opening direction of the branch part C2. There is no need to provide a standing line detection mechanism at the branch portion C2.

[Modification]
As mentioned above, although the example of embodiment which applied this invention was demonstrated, the form which can apply this invention is not restricted to embodiment mentioned above. For example, in the branch part C1 of the first embodiment and the branch part C2 of the second embodiment, the opening direction between two upstream lines (N = 2) and two downstream lines (M = 2) However, the number of N and M is arbitrary, and it is also possible to apply this embodiment to a branch section having a complicated configuration that switches the paths of three or more sets of parallel lines. is there. This can be realized by combining a plurality of any of the branch portions C1 and C2. At that time, it is also possible to combine the upward / downward direction of the branch part C2 in the reverse direction.
