Description

  The present invention relates to a crossing control device and a crossing control method.

  Conventionally, a crossing control device including a crossing warning section, a crossing controller, and a control circuit is known. A railroad crossing warning section is a section defined by an alarm start point and an alarm stop point based on the railroad crossing provided on the track. The alarm start point is set at the rear of the course of the railroad crossing alarm section, and the alarm stop point is In the crossing warning section, it is set ahead in the course. Normally, the alarm start point is provided with a railroad crossing controller that detects that the train has entered the railroad crossing warning section and outputs an approach detection signal, and the alarm stop point indicates that the train has passed the railroad crossing warning zone. A railroad crossing controller that detects and outputs a passage detection signal is provided. When the approach detection signal is supplied, the control circuit outputs a warning start signal to the level crossing warning device, lowers the barrier, and sounds the alarm to let people and vehicles enter the level crossing road. The intrusion is prevented in advance, and when a passage detection signal is supplied thereafter, an alarm stop signal is output, thereby raising the shut-off can and terminating the alarm.

  As for this type of level crossing control device, for example, Patent Document 1 discloses a level crossing control system including an in-vehicle device and a ground device. The in-vehicle device includes a positioning unit that detects the position of the own train using a GPS satellite, and a communication unit that communicates with the ground device about information necessary for supporting the control of the crossing. . The ground device includes a communication unit that communicates with the in-vehicle device, and the train is within a predetermined distance before the crossing based on the train position obtained by the positioning unit in either the in-vehicle device or the ground device. If it is determined that, a shut-off instruction means for issuing a shut-off instruction to the railroad crossing control device is provided.

  Patent Document 2 discloses an on-board device that transmits train information indicating a train type of whether the own train is a passing train or a stop train to the station, to the ground side via an ATS transmitter / receiver and a car upper, A train information detection device that receives train information from a child via a train information receiving ground element, and a driving start point of a railroad crossing device at a station departure direction based on the train information transmitted from the train information detection device. There has been disclosed a railroad crossing control system including a railroad crossing control device that controls a driving time to be a fixed time regardless of the type.

  By the way, the operation time of the railroad crossing warning device is determined to be about 30 to 40 seconds per train. For example, when the track ahead of the railroad crossing is seen in the traveling direction of the train, the main line side (for example, going straight) Time difference between the train traveling on the side) and the train traveling on the sub main line side (for example, the branch side). That is, the alarm start point is usually set based on the traveling speed of the train traveling on the main line side, but the speed limit is applied to the train traveling on the sub main line side, so the transit time is longer than the train traveling on the main line side. The operation time of the railroad crossing warning device becomes longer by the amount of delay, and there is a problem that the smoothing of general traffic on the railroad crossing is hindered.

  However, there is no prior art that can solve the above-described problem of difference in transit time. For example, the railroad crossing control system disclosed in Patent Document 2 sets a warning start point for a railroad crossing on the basis of whether the own train is a passing train or a stop train for the station. On the other hand, since the passage time difference due to the difference in the route between the sub main line side and the main line side occurs regardless of stoppage or passage to the station, the problem cannot be solved.

  The subject of this invention is providing the level crossing control apparatus and level crossing control method which can implement | achieve smoothing of the general traffic in a level crossing road.

  The present invention is a railroad crossing control device used in a line section that is branched into a main line and a sub main line ahead of a railroad crossing in the traveling direction of a train, and includes a control unit in order to solve the above-described problem. . The control unit generates a first alarm start signal when the train travels on the main line, generates a second alarm start signal when the train travels on the sub main line, and the alarm start position by the second alarm start signal is advancing. It is ahead of the alarm start position by the first alarm start signal when viewed in the direction.

  According to the above-described configuration, the control unit configuring the railroad crossing control device according to the present invention generates the first and second alarm start signals, taking into account the difference in the route of the passing train. Since the alarm start position by the second alarm start signal is ahead of the alarm start position by the first alarm start signal in the traveling direction, between the train traveling on the main line side and the train traveling on the sub main line side. The difference in the passing time of the level crossing warning section that occurs can be eliminated by the difference in the alarm start position, and smoothing of general traffic on the level crossing road can be realized.

  As described above, according to the present invention, it is possible to provide a railroad crossing control apparatus that can realize smoothing of general traffic on a railroad crossing.

  Other objects, configurations and advantages of the present invention will be described in more detail with reference to the accompanying drawings. The accompanying drawings are merely examples.

  1 to 4, the same reference numerals indicate the same or corresponding parts. The railroad crossing control device 6 according to the embodiment of the present invention is used for a line section that is branched into a main line 10 and a sub-main line 11 ahead of the level crossing road 2 in the traveling direction F of the train 7, 1st train detector 61, 2nd train detector 62, 3rd train detector 63, and control part 64 are included. First, specifically, the track facility in FIG. 1 includes a track 1, a railroad crossing 2, a branching device 3, a railroad crossing warning device 4, an interlocking device 5, and a railroad crossing control device 6.

  The line 1 is branched into a main line 10 and a sub main line 11 by a branching device 3 beyond a railroad crossing 2 that intersects the line 1 when viewed in the traveling direction F of the train 7. The track 1 in FIG. 1 has railroad crossing alarm sections 101 and 102 defined by alarm start points P1 and P2 and an alarm end point P0, respectively. The alarm start points P1 and P2 are set behind the course of the railroad crossing warning sections 101 and 102, and the alarm end point P0 is set ahead of the course of the railroad crossing road 2 within the railroad crossing alarm sections 101 and 102.

  Usually, the alarm start points P1 and P2 and the alarm end point P0 are such that the train 7 can pass through the level crossing road 2 and the level crossing warning sections 101 and 102 provided with the level crossing road 2 in about 30 to 40 seconds. Therefore, the distance between the railroad crossing alarm sections 101 and 102 is set by adjusting the alarm start points P1 and P2 according to the traveling speed of the passing train. That is, when the train 7 travels on the main line side (for example, straight side), the alarm start point is P1, and when the train 7 travels on the sub-main line side (for example, the branch side), the alarm start point is P2. The traveling speed difference is eliminated by the distance difference G between the level crossing warning sections 101 and 102.

  The railroad crossing warning device 4 is installed on the railroad crossing 2 and controls the intrusion of a person or a vehicle into the railroad crossing 2 by raising and lowering a notch (not shown) and sounding the alarm.

  The first train detector 61 is installed in front of the railroad crossing 2 in the traveling direction F of the train 7 in the railroad crossing warning section 101, and generates the first train detection signal S61 when the train 7 is detected. The first train detector 61 is provided at the alarm start point P1 and detects that the train 7 has entered the railroad crossing alarm section 101 by a known track circuit or ground unit.

  The second train detector 62 is installed in front of the level crossing road 2 in the traveling direction F of the train 7 in the level crossing warning section 102 and before the first train detector 61 to detect the train 7. Then, the second train detection signal S62 is generated. The second train detector 62 is provided at the alarm start point P <b> 2 and detects that the train 7 has entered the railroad crossing alarm section 102.

  The third train detector 63 is installed behind the railroad crossing 2 in the traveling direction F of the train 7 in the railroad crossing warning sections 101 and 102, and generates a third train 7 detection signal S63 when the train 7 is detected. The third train detector 63 is provided at the alarm end point P0 and detects that the train 7 has passed through the railroad crossing alarm sections 101 and 102.

  The interlocking device 5 is installed in front of the first train detector 61 when viewed in the traveling direction F of the train 7, and transmits route information of the train 7. The route information to be transmitted can include information on whether the train 7 travels on the main line 10 or the sub-main line 11, the traveling speed of the train 7, the type of express, express or slow operation, and the like. . The control unit 64 grasps in advance which of the main line 10 and the sub main line 11 the train 7 travels based on the route information of the train 7 input from the interlocking device 5.

  When the first and second train detection signals S61 and S62 are supplied, the control unit 64 outputs the level crossing alarm start signal S64 to the level crossing alarm device, thereby lowering the barrier cannula and ringing the alarm device. To prevent people and vehicles from entering the railroad crossing 2 and then when the third train detection signal S63 is supplied, the railroad crossing alarm stop signal S65 is output to raise the barrier and End the ringing of the vessel.

  1 generates a railroad crossing warning start signal S64 based on the first train detection signal S61 when the train 7 travels on the main line 10, and when the train 7 travels on the sub main line 11, the second train A crossing warning start signal S64 is generated based on the detection signal S62, and the generated crossing warning start signal S64 is supplied to the crossing warning device 4. The alarm start position set by the second train detection signal S62 is ahead of the alarm start position set by the first train detection signal S61 in the traveling direction F of the train 7 by the distance difference G.

  The crossing warning device 4 starts a predetermined warning operation based on the crossing warning start signal S64 and the crossing warning stop signal S65.

  By the way, as already explained, the operation time of the railroad crossing warning device is determined to be about 30 to 40 seconds per train. For example, the trajectory in front of the railroad crossing 2 as seen in the traveling direction F of the train 7 is In the case of branching, there is a time difference in the passing time of the railroad crossing warning section 101 between the train 7 traveling on the main line 10 side (for example, straight traveling side) and the train 7 traveling on the sub-main line 11 side (for example, branching side). That is, the alarm start point P1 is normally set based on the traveling speed of the train 7 traveling on the main line 10 side. However, the train 7 traveling on the sub main line 11 side is limited in speed. The operation time of the railroad crossing warning device is longer than the traveling train 7 by the time it takes to pass through the railroad crossing warning zone 101. In short, in the case of the branch-side train 7, there is a problem that the alarm time, that is, the time during which the circuit breaker goes down, becomes longer, so particularly when the distance between the railroad crossing and the branching device 3 is narrow, for example, around the station As a result, there arises a problem that the smoothing of general traffic on the railroad crossing 2 is hindered.

  In order to solve the above-described problem, the crossing control device 6 according to the embodiment of the present invention includes a control unit 64. The control unit 64 generates a railroad crossing warning start signal S64 based on the first train detection signal S61 when the train 7 travels on the main line 10, and the second train detection signal S62 when the train 7 travels on the sub main line 11. The crossing warning start signal S64 is generated based on the difference between the passing time of the crossing warning section 101 generated between the train 7 traveling on the main line 10 side and the train 7 traveling on the sub main line 11 side. It is eliminated by the distance difference G. That is, when the train 7 travels on the main line 10 side (for example, the straight side), the alarm start point is P1, and when the train 7 travels on the sub-main line 11 side (for example, the branch side), the alarm start point is set to P2. The difference in train traveling speed can be eliminated by the distance difference G between the level crossing warning sections 101 and 102, and smoothing of general traffic on the level crossing road 2 can be realized.

  FIG. 3 is a diagram schematically showing a configuration of a crossing blocking device according to another embodiment of the present invention, and FIG. 4 is a diagram showing an operation step of the crossing blocking device of FIG. The embodiment of FIGS. 3 and 4 is different from the embodiment of FIGS. 1 and 2 in that the alarm start time is varied depending on the time element. Hereinafter, the difference will be mainly described.

  The control part 64 which comprises the level crossing control apparatus 6 of FIG.3 and FIG.4 has the timepiece table part 65, and the alarm start time set by the train detection signal S61 travels on the main line 10 side (for example, straight ahead side). The train 7 traveling on the side of the secondary main line 11 (for example, the branch side) is delayed from the train 7 to be performed. The time element table unit 65 is an arithmetic processing function in the control unit 64 and constitutes the control unit 64 as a software component.

  The embodiment shown in FIGS. 3 and 4 can have all the advantages described with reference to FIGS. Further, in the embodiment shown in FIGS. 3 and 4, the time difference (and the distance difference G due to the time difference) is set by the calculation process of the timepiece table unit 65, so that the equipment cost on the ground side can be reduced and the diagram can be reduced. It is possible to efficiently cope with changes in the traveling speed of passing trains due to revisions.

  Although the contents of the present invention have been specifically described above with reference to the preferred embodiments, it is obvious that those skilled in the art can take various modifications based on the basic technical idea and teachings of the present invention. It is.

1 railroad track, 2 railroad crossing, 6 railroad crossing control device, 61-63 first to third train detectors, 64 control unit, 65 hour base table unit, 7 trains.
