Description

The present invention relates to a remote open railroad crossing control device capable of remotely controlling a railroad crossing.

At railroad crossings where railroads and roads intersect, railroad crossing protection equipment is provided to protect passing pedestrians and automobiles from colliding with trains and to ensure safe operation of trains. A typical example of railroad crossing safety equipment is a railroad crossing gate. A railroad crossing barrier lowers the barrier pole when a train approaches the railroad crossing, and raises the barrier pole when the train passes the railroad crossing. As a method of detecting the approach and passage of a train to a railroad crossing, for example, a method of installing a railroad crossing controller, which is a type of track circuit, is known. In recent years, based on the premise of a train control system that uses wireless communication between the ground and on-board trains, methods have been proposed in which ground equipment controls the start and end of level crossing warnings according to the train's position and speed. (See Patent Document 1, for example).

As described above, the road traffic blocking state in which the road traffic at the railroad crossing is blocked by lowering the blocking rod due to the approach of the train is maintained until the train passes the railroad crossing. Therefore, if the train stops for some reason in the blocked state, the blocked state of the railroad crossing continues. For example, in the event of an emergency stoppage of all trains in the vicinity due to various reasons such as overhead line power outages or reception of train protection radio, all trains will be suspended until safety is confirmed and train operations are resumed. The train remains stopped at that position. If train operation is stopped in a blocked state, the blocked state continues for a long time until train operation is resumed, so road traffic crossing the railroad crossing has been obstructed for a long time.

The problem to be solved by the present invention is to provide a technology that can eliminate the obstruction of road traffic for a long period of time when train operation is stopped when a railroad crossing is blocked.

Also, in the description of the drawings, the same reference numerals are given to the same elements.

[System configuration]
FIG. 1 shows an application example of the remote opening type railroad crossing control device 10 of the present embodiment. The remote open railroad crossing control device 10 of this embodiment is a device for ensuring safe train operation at railroad crossings. Wireless communication with the on-board device 22 and wireless communication with the railroad crossing controller 32 of the railroad crossing safety equipment 30 installed at the railroad crossing CR are possible.

The remote open-type railroad crossing control device 10 manages railroad information including the position and speed of each train 20 and the direction of travel such as the upward direction and the downward direction. The "position" of the train is the position on the track expressed in kilometers, but it may be geographical position information such as latitude and longitude. The train location information may be acquired by the remote open type railroad crossing control device 10 performing wireless communication with the on-board device 22 of each train 20, or may be obtained from another device such as a traffic control device installed in the central control room. may be obtained from the device.

At the railroad crossing CR where the railway and the road intersect, railroad crossing safety equipment such as a railroad crossing gate 34, a railroad crossing alarm 36, and a railroad crossing controller 32 installed in a device box near the railroad crossing to control each of these devices is provided. A facility 30 is provided. The railroad crossing controller 32 has a wireless communication device, and is capable of wireless communication with each device installed in the central control room, such as the remote opening type railroad crossing controller 10 and the operation control device, via the communication network N. be. Then, the railroad crossing controller 32, in accordance with the control information received from the operation management device, the remote open railroad crossing controller 10, etc., lowers or raises the blocking pole of the railroad crossing gate 34, and starts or ends the ringing of the railroad crossing alarm 36. It performs warning control of the railroad crossing CR and transmits a signal indicating the railroad crossing state of the railroad crossing gate 34 to the remote open railroad crossing control device 10 . The "railroad crossing state" of the railroad crossing barrier 34 indicates whether the blocking rod of the railroad crossing barrier 34 is lowered or raised. , and an "open state" in which the blocking rod is raised. In this embodiment, the "blocking state" includes not only the descent of the railroad crossing gate 24, but also the ringing of the railroad crossing warning device 36 of the railroad crossing CR and the blinking of the warning light. means that it is impossible to Similarly, the "open state" includes not only the rise of the railroad crossing gate 24, but also the suspension of the ringing of the railroad crossing warning device 36 and the extinguishing of the warning light, and the state in which road traffic intersecting with the railroad crossing CR can pass. means As for the "open state", the railroad crossing gate 24 is raised, but the railroad crossing warning device 36 continues to ring and the warning light continues to flash.

The remote open railroad crossing control device 10 is capable of remote control of the railroad crossing barrier 34 as a separate control from alarm control such as alarm start and end based on control conditions determined by train position and the like. Utilizing this fact, the remote open type railroad crossing control device 10 remotely controls the railroad crossing gate 34 of the railroad crossing according to the train position around the railroad crossing based on the train location information when the train operation is stopped. , to avoid the continuation of the railroad crossing blocking for a long time when the train operation is stopped. Specifically, when it is determined that the train operation is stopped, the level crossing barrier 34 is in the closed state, and if there is no train approaching the railroad crossing position, the level crossing barrier that was in the closed state 34 is remotely controlled to be in an open state to allow passage of road traffic crossing the railroad crossing CR. Then, when the resumption of operation is grasped, the railroad crossing barrier 34, which has been in the open state, is remotely controlled so as to be in the blocking state again, thereby blocking the road traffic of the railroad crossing CR. In the present embodiment, "train operation stoppage" means stopping all trains within a target range due to, for example, an overhead line failure or reception of a train protection radio signal. The target range for determining that the operation is stopped may be, for example, the control target range of the remote open type railroad crossing control device 10, or the railroad crossing among a plurality of divided ranges obtained by dividing the control target range based on the feeding range or the like. The range may include CR. The remote open railroad crossing control device 10 grasps the stoppage and resumption of train operation based on a signal input from an external device such as an operation control device or an operation input by a dispatcher. Further, the “stop of train operation” may include a stop of operation in which the estimated time from the stop of operation of the train to the restart of operation is equal to or longer than a predetermined time.

More specifically, when the remote opening type railroad crossing control device 10 recognizes that the operation has stopped, it extracts railroad crossings CR whose railroad crossing gates 34 are in the closed state from among the railroad crossings CR under management. The railroad crossing state of the railroad crossing gate 34 is received and acquired from the railroad crossing controller 32 concerned. A railroad crossing passing train existing near the extracted railroad crossing CR is determined, and whether or not the determined railroad crossing passing train is approaching the railroad crossing CR is determined.

FIG. 2 is a diagram for explaining determination of a train passing a railroad crossing. In FIG. 2, for simplicity of explanation, one railroad crossing CR that intersects one railroad track is exemplified, and only trains traveling in one direction (right direction in the figure: downward direction) are exemplified. The same applies to railroad crossings that intersect a plurality of tracks in which trains travel in different directions. As shown in FIG. 2, a railroad crossing passing range, which is a range including the railroad crossing position, is defined for the railroad crossing CR. The railroad crossing passage range is determined so that the train 20 approaching the railroad crossing CR is positioned within that range, and can be, for example, the range from the start point to the end point of alarm control for the railroad crossing CR. A train 20 located in this railroad crossing passing range is determined as a railroad crossing passing train. In addition, a crossing range that is a partial range of the railroad crossing passing range and includes the railroad crossing position is defined. It is determined that a railroad crossing passing train located in this range is approaching the railroad crossing position, and that a railroad crossing passing train not located is not approaching. In FIG. 2, only trains traveling in one direction are shown, but railroad crossing passing ranges and crossing ranges are determined for different traveling directions such as the upward direction and the downward direction.

The approaching range is determined in order to avoid danger that may occur when the railroad crossing gate 34 is opened. In other words, when the train 20 is stopped on a railroad crossing, road traffic that intersects the railroad crossing cannot pass. As will be described later, after confirming that the train 20 has stopped, the crossing barrier 34 is opened. Therefore, it is desirable to keep the railroad crossing gate 34 in the blocking state. Thus, when the train 20 is stopped on or near the railroad crossing, if the railroad crossing gate 34 is opened, a vehicle that erroneously tries to enter the railroad crossing or crosses the narrow gap between the train 20 and the railroad crossing is prevented from crossing. In order to prevent the crossing gate 34 from being opened when there is a train 20 approaching the railroad crossing, the pedestrian crossing range is determined. In addition, assuming an error occurring in the position of the train 20, the range including the railroad crossing is defined as the starting range.

The remote open railroad crossing control device 10 manages track information as the "position" of the train 20, for example, the position of a predetermined part of the train, such as the leading end of the leading car. The position of the train 20 is expressed in kilometers. As for the railroad crossing passage range, it is determined whether or not the train 20 is positioned within the railroad crossing passage range, depending on whether the position of the train 20 is within the railroad crossing passage range. Further, regarding the approaching range, it is determined whether or not the train 20 is located in the approaching range based on whether or not the on-rail range obtained from the position of the train 20 overlaps the approaching range. The on-rail range of the train 20 is obtained as a length range obtained by adding a predetermined allowance distance to the train length of the train 20 with reference to the position of the train. In the example of FIG. 2, the train 20B is located in the railroad crossing passage range and is not located in the crossing range, so it is determined that the train is passing the railroad crossing and is not approaching the railroad crossing position. Since the trains 20A and 20C are not located within the railroad crossing passing range, they are not railroad crossing passing trains.

If the remote open type railroad crossing control device 10 determines that none of the trains passing through the railroad crossing is approaching the railroad crossing position for the railroad crossing CR in which the railroad crossing barrier 34 is in the blocked state, then the railroad crossing barrier of the railroad crossing CR is operated. 34 is released. FIG. 3 is a diagram for explaining the opening of the railroad crossing gate 34. As shown in FIG. As shown in FIG. 3, the remote open railroad crossing control device 10 determines whether or not the train passing the railroad crossing is stopped ((1) in FIG. 3). If it is determined that all trains passing through the railroad crossing have stopped, remote control is performed to open the railroad crossing gate 34 ((2) in FIG. 3). The remote control of the railroad crossing barrier 34 transmits control information for opening the railroad crossing barrier 34 to the railroad crossing controller 32, and the railroad crossing controller 32 raises the barrier pole of the railroad crossing barrier 34 according to the received control information. This is done by opening the It should be noted that when the crossing rod of the railroad crossing barrier 34 is raised, the ringing of the railroad crossing alarm 36 and the flashing of the warning light may be stopped at the same time, or the ringing of the railroad crossing alarm 36 and the flashing of the warning light may be stopped without stopping. Blinking may be continued.

By opening the railroad crossing gate 34, road traffic can pass through the railroad crossing. At that time, the trains passing the railroad crossing are stopped, and the safety of the railroad crossing is ensured. . As the deterrence process, for example, a process of transmitting a signal instructing the train to stop outside the level crossing to a train passing the level crossing, or a process of transmitting a signal notifying that the level crossing is open to the passing train. can be realized by In addition, the railroad crossing passing train is not approaching the railroad crossing position. In other words, since there are no trains on the railroad crossing or in the vicinity of the railroad crossing, road traffic at the railroad crossing is not obstructed. In addition, since there is no train stopping near the railroad crossing, road traffic at the railroad crossing is not disturbed.

After that, when the remote opening type railroad crossing control device 10 grasps that train operation can be resumed, it again shuts off the open railroad crossing gate 34 . FIG. 4 is a diagram for explaining the blocking of the railroad crossing gate 34. As shown in FIG. As shown in FIG. 4, the remote opening type railroad crossing control device 10 first performs remote control to put the railroad crossing barrier 34 in the blocking state ((1) in FIG. 4). Subsequently, deterrence cancellation processing for canceling the deterrence processing performed so that the train passing the railroad crossing does not approach the railroad crossing is performed ((2) in FIG. 4). The deterrence cancellation process corresponds to the deterrence process ((3) in FIG. 3). It can be realized by processing such as transmitting a signal to notify the train passing the railroad crossing that it is in the state. In this manner, after the road traffic is cut off by setting the crossing barrier 34 to the blocked state, the train passing the crossing can enter the crossing, thereby ensuring the safety of the crossing.

Further, if the remote open type railroad crossing control device 10 determines that the train passing through the railroad crossing is approaching the railroad crossing position, the railroad crossing barrier 34 of the railroad crossing CR is opened. and remain in the cut-off state. FIG. 5 shows an example of a state in which a railroad crossing train is approaching a railroad crossing position. In the example of FIG. 5, the train 20D is located in the railroad crossing passing range and also in the approaching range, so it is determined to be a passing train approaching the railroad crossing position. If such a train exists, the remote opening type railroad crossing control device 10 keeps the railroad crossing barrier 34 in the blocked state.

[Function configuration]
FIG. 6 is a block diagram showing the functional configuration of the remote open railroad crossing control device 10. As shown in FIG. 6, the remote open railroad crossing control device 10 includes an operation unit 102, a display unit 104, a sound output unit 106, a wireless communication unit 108, a wired communication unit 110, a processing unit 200, and a storage unit. 300, and can be configured as a kind of computer system.

The operation unit 102 is realized by, for example, an input device such as a keyboard, mouse, touch panel, and various switches, and outputs an operation signal according to the operation performed to the processing unit 200 . The display unit 104 is realized by, for example, a display device such as a liquid crystal display or a touch panel, and performs various displays according to display signals from the processing unit 200 . The sound output unit 106 is realized by, for example, an audio output device such as a speaker, and outputs various sounds according to the audio signal from the processing unit 200 . The wireless communication unit 108 is implemented by a wireless communication device, connects to the communication network N, and performs wireless communication with various external devices such as the on-board device 22 of each train 20 and the railroad crossing controller 32 of the railroad crossing security equipment 30. conduct. The wired communication unit 110 is realized by a wired communication device, and performs wired communication with various external devices such as a train operation management device.

The processing unit 200 is a processor realized by an arithmetic device or an arithmetic circuit such as a CPU (Central Processing Unit) or an FPGA (Field Programmable Gate Array). Overall control of the remote opening type railroad crossing control device 10 is performed based on input data and the like. In addition, the processing unit 200 includes, as functional processing blocks, a track management unit 202, a train operation grasping unit 204, a railroad crossing state acquisition unit 206, a railroad crossing passing train determination unit 208, an oncoming train determination unit 210, and a stop determination unit. 212 , remote barrier control 214 , and departure control 216 . Each of these functional units of the processing unit 200 can be realized in software by the processing unit 200 executing a program, or can be realized by a dedicated arithmetic circuit. In this embodiment, the former is realized by software.

The train location management unit 202 manages rail location information 310 including the position, speed, and traveling direction of each train 20 . The train location information 310 may be obtained by performing wireless communication with the on-board device 22 of each train 20 via the wireless communication unit 108, or may be obtained from another device such as an operation management device via the wired communication unit 110. You may acquire by performing wired communication.

The train operation grasping unit 204 grasps the stop of the train operation by inputting an operation or a signal indicating that the train operation has been stopped. Further, by inputting an operation or a signal to the effect that train operation has been resumed, the resumption of operation can be grasped. Specifically, the train operation grasping unit 204 receives an operation input from a dispatcher via the operation unit 102, and a predetermined signal input from an external device such as an operation management device via the wired communication unit 110 or the wireless communication unit 108. By means of this information, the suspension and resumption of train operation can be grasped. In this embodiment, the stoppage of train operation means the stoppage of all trains within a target range due to a power outage of overhead lines, reception of a train protection radio signal, or the like.

The railroad crossing state acquisition unit 206 receives a signal indicating the railroad crossing state of the railroad crossing barrier 34 from the railroad crossing controller 32 and acquires whether the railroad crossing barrier 34 is in the closed state or the open state. The blocked state of the railroad crossing barrier 34 is a state in which at least the barrier rod of the railroad crossing barrier 34 is lowered, and the open state is a state in which at least the barrier rod is raised.

When the train operation grasping unit 204 grasps that the train operation is stopped and the railroad crossing state of the railroad crossing barrier 34 acquired by the railroad crossing state acquiring unit 206 is the blocked state, the railroad crossing passing train determination unit 208 acquires the railroad crossing information 310. A railroad crossing passing train relating to the railroad crossing is determined based on the railroad crossing position and the railroad crossing position. Specifically, when it is determined that the train operation is stopped, the railroad crossings whose railroad crossing gates 34 are in the closed state are extracted from the managed railroad crossings. Then, trains positioned in the railroad crossing passage range determined for the extracted railroad crossing are determined as railroad crossing passing trains related to the railroad crossing (see FIG. 2). The railroad crossing state of the railroad crossing gate 34 and the railroad crossing range of the railroad crossing are managed in the railroad crossing management information 320 (see FIG. 7), and the position of the train is managed in the track location information 310 .

The approaching determination unit 210 determines whether the train passing the railroad crossing is at the railroad crossing position based on whether or not the predetermined range including the railroad crossing position overlaps with the railroad crossing range of the train passing the railroad crossing obtained from the position of the train passing the railroad crossing and the given train length. It is determined whether or not it is on the way. Specifically, based on the position of the train passing through the railroad crossing determined by the railroad crossing train determining unit 208, the range of the length of the train plus a predetermined allowance distance is obtained as the range of the length of the train. Then, if the obtained train location range overlaps with the approaching range, it is determined that the railroad crossing passing train is approaching the railroad crossing position, and if not overlapped, it is determined that the train is not approaching.

The stop determination unit 212 determines whether or not the railroad crossing train is stopped based on the railroad information 310 . That is, if the speed of the railroad crossing passing train managed in the railroad information 310 is zero, it is determined that the railroad crossing passing train has stopped.

When the stop determination unit 212 determines that the train passing the railroad crossing has stopped and the approaching determination unit 210 determines that the train passing the railroad crossing is not approaching the railroad crossing, the remote gate control unit 214 controls the departure control unit. After the departure deterrence processing by 216 is completed, remote control is performed to open the railroad crossing barrier 34 (see FIG. 3). Further, after the train operation grasping unit 204 grasps the train operation stop, the departure control unit 216 performs departure deterrence processing, and the remote control unit 214 performs remote control to open the railroad crossing gate 34, the train operation When the comprehension unit 204 comprehends the resumption of operation, remote control is performed so that the crossing barrier 34 is in the blocked state (see FIG. 4). Remote control of the railroad crossing barrier 34 is realized by transmitting control information to the railroad crossing barrier 34 to open or close the railroad crossing barrier 34, and the operation of the railroad crossing barrier 34 is controlled by the railroad crossing barrier 32 , is realized by performing drive control for lowering or raising the blocking rod of the railroad crossing gate 34 in accordance with the received control information.

A departure control unit 216 performs deterrence processing so that the train passing the railroad crossing should not approach the railroad crossing when the railroad crossing determining unit 210 determines that the train passing the railroad crossing is not approaching the railroad crossing. As the deterrence process, for example, a signal instructing the train to stop outside the railroad crossing is transmitted to the train passing the railroad crossing, or a signal is transmitted to the train passing the railroad crossing to notify that the railroad crossing is open. (See Figure 3). In addition, after remote control by the crossing machine remote control unit 214 to put the railroad crossing gate 34 in the blocking state, deterrence cancellation processing for canceling the deterrence processing performed so that the train passing the railroad crossing does not approach the railroad crossing is performed. As the deterrence cancellation process, for example, a signal to cancel the instruction to stop outside the railroad crossing is transmitted to the train passing the railroad crossing, or a signal notifying that the railroad crossing is in a closed state is transmitted to the passing railroad crossing train. (see FIG. 4).

The storage unit 300 is implemented by a storage device such as an IC (Integrated Circuit) memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory), or a hard disk. In addition to storing programs, data, etc. for controlling the operation unit 200, it is used as a work area for the processing unit 200, and temporarily stores calculation results executed by the processing unit 200, input data from the operation unit 102, and the like. be. In this embodiment, the storage unit 300 stores a railroad crossing control program 302 , railroad location information 310 , railroad crossing management information 320 , and an operation stop flag 330 .

Operation stop flag 330 is a flag indicating whether or not train operation is stopped. The train operation grasping unit 204 grasps whether or not the train operation has been stopped.

FIG. 7 is a diagram showing an example of the railroad crossing management information 320. As shown in FIG. As shown in FIG. 7, the railroad crossing management information 320 stores, for each railroad crossing, a railroad crossing ID that is identification information for the railroad crossing, a railroad crossing position, a railroad crossing state, and crossing gate control history information in association with each other. . A railroad crossing position is a position along a track expressed in kilometers. The railroad crossing state stores information indicating whether the railroad crossing gate 34 of the railroad crossing is in the blocked state with the blocking rod lowered or in the open state with the blocking rod raised. The railroad crossing state is received from the railroad crossing controller 32 that controls the railroad crossing gate 34 . The gate control history information is a history of remote control of the railroad crossing gate 34 of the railroad crossing when the train operation was stopped, and includes the time when the train operation was stopped, the time when the train operation was restarted, and the time when the train operation was stopped. are stored in association with the train numbers of the trains passing through the railroad crossing determined in .

[Process flow]
FIG. 8 is a flowchart for explaining railroad crossing control processing performed by the remote open railroad crossing control device 10 . This processing is performed in parallel for each railroad crossing CR managed by the remote open railroad crossing control device 10 .

When the train operation grasping unit 204 grasps that the train has stopped operating (step S1: YES), if the railroad crossing gate 34 of the target railroad crossing CR is in the blocked state (step S3: YES), the railroad crossing passing train determination unit 208 , railroad crossing passing trains related to the target railroad crossing CR are determined (step S5). Next, the approaching determination unit 210 determines whether or not the determined railroad crossing passing train is approaching the railroad crossing position, and if none of the railroad crossing passing trains is approaching the railroad crossing (step S7: NO), then A stop determination unit 212 determines whether the railroad crossing passing train is stopped. If it is determined that all railroad crossing passing trains are stopped (step S9: YES), the crossing gate remote control unit 214 remotely controls the crossing gate 34 of the target railroad crossing CR from the closed state to the open state. (step S11). Then, the departure control unit 216 performs deterrence processing so that the train passing the railroad crossing does not approach the railroad crossing (step S13).

If the railroad crossing gate 34 of the target railroad crossing CR is in the open state (step S3: NO), or if it is determined that any train passing through the railroad crossing is approaching the railroad crossing position (step S7: YES), If it is determined that the train passing through the railroad crossing has not stopped (step S9: NO), the railroad crossing gate 34 of the target railroad crossing CR remains in the railroad crossing state, and the process returns to step S1.

Thereafter, when the train operation grasping unit 204 grasps the resumption of train operation (step 15: YES), the crossing gate remote control unit 214 changes the crossing gate 34 of the target crossing CR from the open state to the closed state. Remote control is performed (step S17). Then, the departure control unit 216 performs deterrence cancellation processing for canceling the deterrence processing performed to prevent the train passing the railroad crossing from approaching the railroad crossing (step S19). After performing the above processing, the process returns to step S1, and the same processing is performed for the next operation stop.
