Description

  The present invention relates to a railroad crossing warning system for controlling a warning output of a railroad crossing alarm installed at a railroad crossing, and more particularly to a wireless railroad crossing warning system for notifying train information from an onboard device to a railroad crossing warning control device. More particularly, the present invention relates to a radio level crossing warning system relating to a level crossing provided in the vicinity of a station.

The most common railroad crossing warning device 20 is of a wired type (see, for example, Non-Patent Document 1), and FIG. 2 (a) showing a schematic configuration thereof in a schematic diagram is a comparison explanation with the railroad crossing warning system of the present invention. A useful part is drawn. For simplicity, an example of a single line is shown.
A level crossing alarm 23 is installed at a level crossing 12 (crossing road) crossing the railroad track 11, and at a distance from the level crossing 12, a level crossing controller 21 (train detection device) that detects the train 10 traveling to the level crossing 12. ) Is attached between them, and the train presence information Q (information indicating whether or not the train has entered the detection target portion or the detection target section of the track 11) from the railroad crossing controller 21 between them. Is input, and a railroad crossing warning control device 22 is provided for controlling the warning light of the railroad crossing alarm 23 and the alarm output of the warning sound generator in accordance with the approach and passage of the train 10 to the railroad crossing 12. Note that a pair of level crossing alarms 23 are installed separately at both ends of the level crossing road.

  These level crossing control elements 21, level crossing alarm control device 22 and level crossing alarm device 23 are connected by a signal cable to complete a level crossing alarm device 20. However, a crossing device is installed at level crossing 12 to raise and lower the crossing bar. Thus, the railroad crossing warning control device 22 is expanded to a railroad crossing control device that performs lifting / lowering control of the blocking rod in addition to the alarm output. That is, a level crossing control device that performs lifting control of the crossing bar corresponds to a level crossing warning control device if the level crossing warning output control is performed. In the track 11, the position where the alarm should be started when the train 10 approaches the railroad crossing is called a railroad crossing alarm start point position ADC, and the position where the alarm should stop immediately after passing the railroad crossing is the railroad crossing alarm end point position BDC. The position where the monitoring state is to be initialized after that is called the railroad crossing alarm reset point position CDC.

  The above is related to the case where the level crossing 12 is away from the station, but the level crossing to be monitored may be provided close to the station. In this case, the railroad crossing in the vicinity of the station transmits alarm control conditions such as the side line evacuation of the preceding train, the passing of the following train to the main line, and the side line turnover train from the station interlocking device to the railroad crossing device via a signal cable. The railroad crossing control device started an alarm in response to this condition. The alarm is terminated under the condition of “no train” in the crossing controller (non-insulated short track circuit) at the end point. A specific example will be described with reference to the drawings. FIG. 2B is a schematic diagram of a conventional wired level crossing alarm control device 25 relating to the level crossing 12 near the station 13.

  The railroad crossing 12 and the Lee station 13 are installed close to the track 11, and the railroad crossing warning start position of the railroad crossing 12 depends on whether the course of the train 10 at the Lee station 13 is the main line 14 or the side line 15. When the ADCs 12 and 13 are so close that the ADC is separated, conventionally, a wired level crossing warning control device 25 is introduced and installed. The wired level crossing warning control device 25 is an extension of the above level crossing warning device 20 so that the interlocking device 26 installed at the station 13 and the level crossing warning control device 22 of the level crossing 12 cooperate. The interlocking device 26 and the railroad crossing warning control device 22 are connected by cable, and the route condition and the opening condition of the turning machine are transmitted from the interlocking device 26 at the station 13 to the railroad crossing alarm control device 22. . The railroad crossing warning control device 22 performs the railroad crossing warning control in consideration of the route condition from the interlocking device 26 in addition to the train presence line information Q.

  More specifically, the railroad crossing warning starting point position ADC is divided into a main line side crossing warning starting point position ADC (14) and a side line side crossing warning starting point position ADC (16). The main line side crossing warning starting point position ADC (14) is used for the level crossing warning control, and when the train route is the side line 15 at the station 13, the side line side crossing warning starting point position ADC (16) is set. Used for level crossing warning control. The main line side crossing alarm starting point position ADC (14) is located in front of the station 13 on the opposite side of the station 13 to the inner railroad crossing 12 of the station 13, that is, the track 11 is connected to the main line 14 and the side line 15 It is set in the place just before branching. On the other hand, the side line side crossing warning starting point position ADC (16) is a track circuit for detecting the train on the side line 15 due to the characteristics of the track circuit 24 for detecting the train installed on the side line 15 of the station 13. Is set to the track circuit section start point 16, which is a breakpoint of the section.

  In such a wired level crossing warning control device 25, conditions such as the train route from the interlocking device 26 and train presence line information of the main line side crossing alarm starting point position ADC (14) or the side line side crossing alarm starting point position ADC (16). Since Q is input to the level crossing warning control device 22, the level crossing warning machine 23 of the level crossing 12 starts to output a warning at an appropriate time reflecting the train route of the adjacent station 13. The level crossing warning end point position BDC and the level crossing warning reset point position CDC that are separated from the station 13 and other stations are those when the level crossing 12 is separated from the station 13 and other stations (see FIG. 2A). Therefore, when the train 10 passes the level crossing alarm end point position BDC, the alarm is stopped, and when the train 10 passes the level crossing alarm reset point position CDC, the monitoring state is initialized.

On the other hand, a railroad crossing warning device that introduces wireless (for example, see Patent Document 1) and a railroad crossing control system that uses both wireless and wired (for example, see Non-Patent Document 2) are also known.
In these radio train control systems, when radios are installed in trains and ground facilities, and the radios of the train approach to a range where transmission is possible with radios installed in the ground equipment, a communication line is established according to a predetermined transmission procedure. To start information transmission. The level crossing control device on the ground receives radio information from the train and controls the start / end of a level crossing alarm. Furthermore, the railroad crossing control device can perform alarm start / end control of the railroad crossing without a railroad crossing controller and related cables by wirelessly receiving “position and speed” information from the train.

If proper information cannot be transmitted / received due to radio interference etc., always prepare a means to stop the train before the railroad crossing and make sure that the railroad crossing is properly interrupted and then before the railroad crossing. The safety of railroad crossing passers-by is ensured by releasing the means to stop the train.
As a specific example, the on-board device recognizes the position of the front railroad crossing from an in-vehicle database or the like, and generates a speed check pattern in the on-board device that stops the train before the railroad crossing. If the on-board device cannot receive the instruction information for deleting the on-board speed check pattern from the crossing control device due to a radio failure or the like, the train driver decelerates according to the speed check pattern and stops before the crossing road.
If there is no radio interference and proper information can be sent and received, the railroad crossing is normally shut off, the on-board device can also receive instruction information to erase the on-board speed check pattern in a timely manner, and the train driver can operate properly. Can continue.

Japanese Patent Laid-Open No. 11-20702

Introduction to Electricity for Railway Engineers Signal Series 8 “Level Crossing Security Device” Japan Railway Electrical Engineering Association October 30, 1997 4th edition issued Takeichi Koichi, “Train Control System by Wireless (ATACS)”, Japan Railway Electrical Engineering Association, April 2006 “Railway and Electrical Technology” Vol. 17, No. 4, pp. 24-27

As described above, in a crossing warning system that introduces radio (see FIG. 2B), it is possible to perform alarm start / end control of the crossing without using a crossing controller or a related cable.
However, in such a conventional wireless level crossing alarm system, when the level crossing and the station are installed close to each other, the interlocking device configures the alarm control conditions for the level crossing, which complicates the logic of the interlocking device. It is in a state where the interlocking device cannot be standardized.
Since no alarms impairs safety, it is a difficult task to configure the conditions from the interlocking device to the railroad crossing with relays, and it is necessary to install an input / output relay rack in the equipment room.
Furthermore, there is a problem that it costs money to install a cable between the equipment room of the station where the interlocking device is installed and the railroad crossing control device.

The crossing controller itself, it should alert from any alarm starting point for you do not know the route of the stations for the train approaching, for relevant starting traffic is unable to determine whether or not to an alarm because it does not know the current- The above problem occurs.
Therefore, when the level crossing warning system is made wireless, it becomes an issue to improve the level crossing warning system so that the level crossing control device installed at the level crossing close to the station can grasp the course of the train at the station alone.

  The wireless railroad crossing warning system of the present invention has been developed to solve such a problem, and is mounted on a train and transmits on-board information including the train position wirelessly. A railroad crossing alarm installed on the railroad crossing of the traveling track, and the railroad crossing based on the train position that is installed on the ground side and receives the train information wirelessly from the onboard device and is included in the train information Is provided for a wireless railroad crossing warning control device that determines the approach and passage of the train to and controls the warning output of the railroad crossing warning device, and the station where the track is divided into a main line and a side line. A wireless railroad crossing warning system comprising a wireless station control device for receiving train information wirelessly from the on-board device and managing a train route, wherein the wireless railroad crossing warning control device relates to the railroad crossing Railroad crossing Each time the train start position is acquired wirelessly and the train start position is acquired wirelessly, the train approach determination to the level crossing and the alarm output control of the level crossing alarm based on the train position and the level crossing alarm start point position, The main line side crossing alarm starting point position and the side line side crossing alarm starting point position are retained as the level crossing alarm starting point position, and the train route information of the level crossing is obtained from the wireless communication of the wireless station control device. According to the train route obtained, one of the main line side crossing warning start point position and the side line side crossing warning start point position is selected and used for the train approach determination. That's it.

  In such a wireless railroad crossing warning system of the present invention, the ground device and the train are controlled wirelessly, but the railroad crossing control device independently receives “position information from the vehicle”. And “Information on route setting and signal indication from station control device”, selecting an appropriate alarm start point, or delaying the alarm start time by a certain time when the departure signal on the route is indicating stop, etc. It becomes possible to carry out the control. Moreover, since the track circuit breaks (insulation insertion points) in the station premises are created mainly by the train length and the operation time interval, the warning time for a crossing tends to be longer than the design warning time. In the case of wireless control, the alarm start point can be determined without being influenced by the physical separation of the track circuit. Furthermore, it is possible to approach the design alarm time by controlling the alarm start time in consideration of the indication of the traffic light.

  That is, the optimal alarm start timing can be controlled according to the train route of the station with the railroad crossing control device alone. In addition to the train route, it is possible to control more finely if the signal display is also acquired wirelessly. In addition, the wireless communication eliminates the installation of relay output racks, cables, etc. across the interlocking device and the railroad crossing, thereby reducing construction costs. Furthermore, there is no need to issue a level crossing control condition from the station interlocking device, and the interlocking connection can be standardized.

About Example 1 of this invention, the structure of a radio | wireless crossing warning system is shown, (a) is a schematic diagram, (b) is a detailed block diagram. (A) is a schematic diagram of the conventional level crossing warning system which concerns on a single level crossing, (b) is a schematic diagram of the conventional level crossing warning system which concerns on a level crossing near a station.

With regard to such a wireless railroad crossing warning system of the present invention, a specific mode for carrying out this will be described with reference to Example 1 shown in FIG.
In addition, since the same reference numerals are given to the same constituent elements as those in the prior art in the illustration, since what has been described in the background art section is also common to the following embodiments, the duplicated description is repeated. Will be omitted, and the description below will focus on differences from the prior art.

  A specific configuration of the wireless railroad crossing warning control device and the wireless railroad crossing warning system according to the first embodiment of the present invention will be described with reference to the drawings.

Here, the case of a single wire is also shown, and FIG. 1A is a schematic diagram of a radio level crossing warning system 50, and FIG. 1B is a more detailed block diagram.
The railroad crossing alarm start point position ADC and the railroad crossing alarm end point position BDC are virtual ones defined by the position data in the on-board database or the ground database, and where the current for detecting the train actually flows. Since it disappears, it is shown by a dotted line in FIG.

  Moreover, the railroad crossing warning starting point position ADC is the main line side crossing warning starting point position ADC (14) when the train route is the main line 14 at the station 13 and the train route is the side line 15 at the station 13. It is a general term for the side line side crossing warning starting point position ADC (15) when the vehicle is on. In the conventional wired level crossing alarm control device 25 described above, the side line side crossing alarm starting point position ADC (16) is fixed to the track circuit section start point 16 due to the dependency on the interlocking device 26, but the wireless level crossing according to the present invention. In the alarm system 50, the wireless railroad crossing warning control device 52 holds the data on the side line side railroad crossing alarm starting point position ADC (15) in the same manner as the main line side crossing warning starting point position ADC (14) and uses it for the train approach determination. Thus, the side line side crossing warning starting point position ADC (15) is not limited to the track circuit section start point 16, but can be flexibly determined according to the conditions of the station 13 and the train 10.

  The wireless level crossing warning system 50 (see FIG. 1) differs from the conventional wired level crossing warning control device 25 (see FIG. 2 (b)) in that an onboard device 51 is used instead of the level crossing controller 21. Is introduced, a wireless level crossing warning control device 52 is replaced with the railroad crossing warning control device 22, and a wireless station control device 59 is replaced with the interlocking device 26 and the station device. is there.

In the wireless level crossing warning system 50 (see FIG. 1), the wireless level crossing warning control device 52 is installed on the ground side in the same manner as the level crossing warning control device 22, and is connected to the level crossing warning device 23 by wire. Like the interlocking device 26, it is installed on the ground side to perform traffic light control at the station 13, and the onboard device 51 is mounted on the train 10.
The level crossing alarm 23 may be the same as the conventional one, and a level crossing breaker may be provided in parallel. When a level crossing breaker is provided in parallel with the level crossing alarm 23, the wireless level crossing warning control device 52 is expanded in function as in the conventional case to become a level crossing control device.

  The on-board device 51 is composed of a fail-safe computer connected to a radio, and a program for obtaining a train position (start position of the own train) from an axle tachometer of the destination train 10 and a preset installation Non-volatile memory that holds the train length of the destination train 10 (the length of the own train) and information related to each level crossing and each station, and appropriate data such as the train identification number for the train position and the train length of the own train In addition, it has train information and a wireless communication program that wirelessly transmits this train information. In addition, as the information related to the level crossing, the position of the level crossing 12 in the line section, the level crossing alarm start point position ADC, the level crossing alarm end point position BDC, and the like described above are defined in so-called kilometers indicating the distance from the base point. Yes.

The information relating to the station includes the position of the station 13 in the line section, the position of the traffic lights at the station 13, the course conditions of the train 10 and other trains at the station 13, and the presence or absence of the side line 15 branched from the main line 14. Etc.
Furthermore, the on-board device 51 may not specify the destination when transmitting train information if there is no concern about interference or the like. However, in order to improve the reliability of communication, the on-board device 51 may specify the destination when transmitting train information. In the case of specifying, the devices 52 and 59 in the close arrangement are integrated with the telegrams by connecting the destinations. For this purpose, the message format has been expanded to include a plurality of destinations.

  Specifically, the track 11 is branched into a main line 14 and a side line 15 at the station 13, and the station 13 and the railroad crossing 12 are installed close to each other on the track 11, and the station If the level crossing alarm starting point ADC of the level crossing 12 is separated depending on whether the route of the train 10 at 13 is the main line 14 or the side line 15, the radio level crossing there The on-board device 51 transmits a telegram of train information to the alarm control device 52 and the wireless station control device 59.

  The wireless station control device 59 controls each traffic light and turning machine at the station 13 based on the train detection by the track circuit of the main line 14 and the side line 15 as well as the interlocking device 26 described above. Although it is installed and wirelessly communicates with the on-board device 51, if the own device is included in the destination of the message transmitted from the on-board device 51, the train identification number required for control of the traffic light etc. Information such as train position is acquired. In addition, the wireless station control device 59 holds in advance the train route information necessary for control of each traffic signal and the switch at the station 13 by data input or the like. By returning the information on the traffic signal wirelessly, it is possible to determine whether the train 10 travels to the main line 14 or the side line 15 at the station 13 and whether or not the travel is permitted. To be notified.

  The wireless railroad crossing warning control device 52 is also composed of a fail-safe computer connected to a wireless device, and includes a wireless communication program for wireless communication with the on-board device 51. This wireless communication program is also a wireless station. As with the control device 59, if the self-device is included in the destination of the message transmitted from the on-board device 51, information such as the train position and the train length required for the crossing warning control is acquired. . Then, when train information is transmitted from the onboard device 51 of the train 10 that has entered the wireless communicable range, when the train information is tried and received normally, a reception ACK to that effect is sent back wirelessly. It has become.

  In addition, this wireless communication program wirelessly transmits a crossing alarm start event and a crossing alarm stop event related to the control of the alarm output of the crossing alarm 23 to the on-board device 51, but the response and timing of the wireless station control device 59 Therefore, interference with the wireless station control device 59 is avoided by transmitting the data slightly shifted. Further, the wireless communication program of the wireless railroad crossing warning control device 52 also receives a reply from the wireless station control device 59 to the onboard device 51, and displays information on the train route and traffic signal information included in the telegram. It is supposed to get. In addition, it is sufficient that the wireless devices of the wireless level crossing warning control device 52, the wireless type station control device 59, and the on-board device 51 can communicate with each other through synchronous communication or asynchronous communication. It may be a wireless device used in the control system, a cheaper version thereof, or another wireless device.

  The wireless level crossing warning control device 52 has the level crossing warning control program 53 installed in the program memory together with the above-described wireless communication program, and the level crossing information relating to the alarm target level crossing is set in the nonvolatile memory for holding data. Has been. Here, the alarm target level crossing refers to the level crossing 12 in which the level crossing alarm 23 connected to be controlled is wired, and the information related to the alarm target level crossing includes the above-described level crossing alarm start point position. ADC, railroad crossing alarm end point position BDC, etc. are defined in kilometer. Moreover, in response to the fact that the track 11 branches into the main line 14 and the side line 15 at the station 13 that is installed in the vicinity of the level crossing 12, the main line side crossing alarm start point position ADC is used as the above level crossing alarm start point position ADC. (14) and a side line side crossing warning starting point position ADC (15) are defined. Furthermore, the memory of the wireless railroad crossing warning control device 52 holds data such as route information of the station 13 and signal display.

  The level crossing warning control program 53 determines whether or not the head of the train has reached the level crossing warning starting point position ADC based on the train position included in the train information received wirelessly before the start of the level crossing warning. The approach of the train 10 to the level crossing 12 to be alarmed is determined, and when it is determined that the train 10 has reached the level crossing alarm starting point position ADC, the level crossing alarm 23 starts alarm output. Moreover, at that time, when the train route of the train 10 is the main line 14 at the station 13, the main line side railroad warning start point position ADC (14) is adopted as the railroad crossing warning start point position ADC, and the train route of the train 10 is When the station 13 is on the side line 15, the side line side crossing alarm start point position ADC (15) is adopted as the crossing alarm start point position ADC.

  Further, the railroad crossing warning control program 53 starts the railroad crossing warning, that is, after the railroad crossing alarm 23 starts alarm output, based on the train position and the train length included in the train information received wirelessly. When it is determined that the train 10 has passed the railroad crossing warning end point position BDC, it is determined whether the train 10 has passed the railroad crossing warning end point position BDC according to whether or not the tail has passed the railroad crossing warning end point position BDC. The railroad crossing alarm 23 stops the alarm output.

  Note that the close arrangement of the railroad crossing 12 and the station 13 affects the operation of the wireless level crossing warning control device 52 when the train 10 travels from the station 13 toward the railroad crossing 12 (FIG. 1). (See (a)), when the train 10 travels in the opposite direction from the railroad crossing 12 toward the train station 13 (not shown), the proximity arrangement between the railroad crossing 12 and the train station 13 is a wireless railroad crossing warning control device. Since the operation of No. 52 is not affected, not only the level crossing alarm end point position BDC but also the level crossing alarm starting point position CDC can be fixed, and the description of the alarm control processing is omitted.

The use mode and operation of the wireless railroad crossing warning system 50 according to the first embodiment will be described with reference to the drawings.
FIG. 1A is an installation state diagram of the wireless railroad crossing warning system 50.

  Assuming that a railroad crossing 12 and a station 13 are installed close to a track 11 on which the train 10 travels (see FIG. 1 (a)), the approaching degree of both the rails 12 and 13 to which the present invention can be applied is as follows. This means that the station 13 is within the range from the level crossing alarm starting point ADC 12 to the level crossing 12 (crossing road). In this embodiment, the level crossing alarm is started in the direction where the station 13 is located. Since the point position ADC is assumed, the station 13 is located between the main line side crossing alarm starting point position ADC (14) and the crossing 12. Further, it is within the communicable range between the wireless level crossing alarm control device 52 installed near the level crossing 12 and wired to the level crossing alarm 23 and the on-board device 51 traveling on the track 11, and 13 is within the communication range between the wireless station control device 59 installed in or near 13 and the on-board device 51 traveling on the track 11.

  In such a place where the ground equipment is installed, the train 10 equipped with the on-board device 51 travels on the track 11 toward the station 13 that is relatively close from the left to the right, for example. When 51 enters the wireless communicable range of the wireless station control device 59, the train identification number (identification information of the own train), the train position (the start position of the own train), and the train length (the length of the own train) are obtained by wireless communication. Is transmitted from the on-board device 51 and reaches the wireless station control device 59. Then, the signal display information at the station 13 and the train route information of the train 10 are returned from the wireless station control device 59 to the on-board device 51 each time. This reply is wirelessly intercepted by the wireless level crossing warning control device 52 regardless of whether the onboard device 51 and the wireless level crossing warning control device 52 can communicate with each other. It is taken into the railroad crossing warning control device 52.

  When the train 10 further travels and approaches the station 13 and the onboard device 51 enters not only the wireless station control device 59 but also the wireless level crossing alarm control device 52, the onboard device 51 wirelessly transmits. The train identification number, the train position, and the train length transmitted in (1) reach both the wireless station control device 59 and the wireless railroad crossing warning control device 52. Also in this case, every time it is received, the above-mentioned reply by the wireless station control device 59 and the wireless interception by the wireless railroad crossing warning control device 52 are performed. The level crossing warning control device 52 makes a determination for the start of the level crossing warning, and determines whether the train 10 proceeds to the main line 14 or the side line 15 based on the train route acquired most recently.

  Then, based on the determination result, when the train 10 proceeds to the main line 14, the main line side railroad warning start point position ADC (14) is adopted as the railroad crossing alarm start point position ADC, and the train 10 proceeds to the side line 15. The side line side crossing warning starting point position ADC (15) is adopted as the level crossing warning starting point position ADC. When it is determined that the train 10 has reached the railroad crossing alarm starting point position ADC, the wireless level crossing warning control device 52 performs start control of alarm output to the railroad crossing alarm 23, and the level crossing alarm 23 emits an alarm light. Flashes and a warning sound is emitted from a warning sound generator. In this way, the alarm start of the crossing 12 is appropriately performed. In addition, when a level crossing breaker is provided in parallel with the level crossing alarm 23, the crossing bar lowers and the level crossing 12 is closed.

  Train information including a train identification number, a train position, and a train length is transmitted from the onboard device 51 by wireless communication even after the start of the railroad crossing alarm, and reaches both the wireless station control device 59 and the wireless railroad crossing alarm control device 52. . After the start of the level crossing alarm, the wireless level crossing warning control device 52 makes a determination to stop the level crossing alarm every time train information arrives, and the train 10 has passed the level crossing alarm end point BDC. If it becomes clear, the wireless level crossing warning control device 52 performs a stop control of alarm output to the level crossing warning device 23, whereby the warning light is turned off and the warning sound generator is quieted at the level crossing warning device 23. Thus, the alarm stop of the level crossing 12 is appropriately performed. In addition, when a level crossing breaker is provided in parallel with the level crossing alarm 23, the cutoff bar rises and the level crossing 12 is opened.

Then, after the train 10 passes the railroad crossing alarm end point position BDC, when the train position at that time is notified from the on-board device 51 to the wireless railroad crossing warning control device 52, the wireless crossing warning control device 52 passes through. The monitoring state based on the wireless communication with the on-board device 51 of the train 10 is reset and the on-board device 51 of the other train 10 waits for the wireless communication to enter the range.
As described above, in the wireless level crossing warning system 50, even if the level crossing 12 to be monitored and the station 13 are installed close to each other, the on-board device 51, the wireless level crossing warning control device 52 on the ground side, and the wireless A railroad crossing warning is appropriately output through wireless communication with the station controller 59.

Further, by performing a consistency check between the information on the level crossing alarm start and level crossing alarm stop received by the on-board device 51 and the train position and holding data, traveling on the train 10 side becomes more appropriate.
Further, the wireless station control device 59 grasps and returns the train route of the train 10 based on the train identification number acquired from the on-board device 51 by wireless communication, and the train position of the train 10 by wireless communication. As necessary, the trains in the station 14 and the side lines 15 are also used to control each traffic signal at the station 13 so that the train operation at the station 13 and nearby is also appropriate. Made.

  When the train 10 travels in the opposite direction from the level crossing 12 toward the station 13 at the level crossing 12, the positional relationship between the level crossing alarm start point position CDC and the level crossing alarm end point position BDC with respect to the level crossing 12 is satisfied. Therefore, in this case, the close arrangement of the level crossing 12 and the station 13 does not affect the operation of the wireless level crossing warning control device 52, and the level crossing warning starting point position CDC is fixed at a predetermined position on the track 11. , The processing content is simplified accordingly.

The radio level crossing warning control device and the radio level crossing warning system of the present invention are not limited to the case of the single line shown in the above-described embodiment, but the level crossing where multiple lines are used and where multiple lines run in parallel It can also be applied to railway crossings.
If proper information cannot be transmitted / received due to radio interference etc., the means to stop the train before the railroad crossing, such as the on-board speed check pattern described above, should be prepared at all times, and the railroad crossing should be properly interrupted. After confirming the above, it is also possible to use it together with the security guarantee method for level crossing passers-by who releases the means to stop the train before the level crossing.
