  FIG. 1 is an overall view of a railway line information transmission system 10 according to the present invention. In FIG. 1, a railway monitoring device 20, an on-vehicle device 30, a central monitoring device 40, and a track 50 are shown.

  The along-line monitoring device 20 is a monitoring device installed along the railway to monitor rainfall, wind speed, falling rocks, avalanches and the like. The along-line monitoring device 20 corresponds to, for example, a rain gauge, an anemometer, a seismometer, or the like. Moreover, the apparatus which judges the presence or absence of a falling rock and an avalanche is also contained. However, it is not limited to devices that monitor only weather conditions and natural phenomena, but includes all devices that monitor events that have occurred along railway lines.

  The on-board equipment 30 is mounted on a train running on the track 50 and moves as the train progresses. When the position of the on-board device 30 is illustrated, a train is located at the place. The on-board device 30 is now moving toward the right side of the drawing.

  The central monitoring device 40 monitors the operation of all trains in the area under its jurisdiction. For example, when passing through a section of the track, a current circuit is formed so that the passage of the train is detected, and in that case, the train's current position is configured to notify the central monitoring device 40 of the passage information of the train. And the passage time of a certain point is known. It is also possible to detect the disruption of the schedule by monitoring the operation of all trains in the jurisdiction.

The train position information 68 indicating the current position of the train may be based on information from the central monitoring device 40 or may be based on a position calculated using GPS. As long as the information is such that the position of the host vehicle can be recognized while the train is running, the acquisition method is arbitrary. For example, it is optional to use a device that reads a distance marker (kilo post) laid along a railway and recognizes it as train position information.

  The train number information 72 is a unique number uniquely assigned to all trains managed by the central monitoring device 40. The train diagram information 74 is a diagram of each train. The train schedule information 74 is basically the same every day if it is normally operated, but it changes every moment when there is a temporary train or a delay occurs for some reason. Therefore, it is desirable that the train schedule information 74 is updated by communication with the central monitoring device 40 that monitors the operation status of the train.

  As for the monitoring device position information 76 of the along-line monitoring device 20, since the along-line monitoring device 20 is fixed, for example, the monitoring device position information 76 can be determined from the viewpoint of how far away from a nearby kilometer post. .

The railway monitoring control unit 88 instructs the railway monitoring transmission / reception unit 86 to perform communication based on the information stored in the railway monitoring storage unit 82. Here, the monitoring device position information 84 of the roadside monitoring device 20 is the position information of the roadside monitoring device 20, for example, as described above, the monitoring device position information from the viewpoint of how far away from the nearby kilometer post. 84 can be defined.

  The railway line information transmission system 10 includes train position information 68 indicating the current position of the train stored in the on-board storage unit 62, and monitoring device position information 84 of the line monitoring device 20 stored in the line monitoring storage unit 82. When the on-board device 30 and the along-line monitoring device 20 approach each other within a predetermined distance, the on-vehicle control unit 67 and the along-line monitoring control unit 88 monitor the on-vehicle transmission / reception unit 66 and the along-line monitoring. Control to establish communication with the transmission / reception unit 86 is performed. For example, when the train station monitoring device 20 has the train position information 68 and the monitoring device position information 84 approaching within 3 kilometers, the track monitoring transmission / reception unit 86 transmits information such as the air volume and snowfall collected by the station monitoring device 20. As described above, the along-line monitoring control unit 88 can issue an instruction, or the on-board device control unit 67 transmits a signal indicating that communication is possible to the along-line monitoring device 20. Good.

  In the on-board storage unit 62 of the on-board device 30, as described above, the monitoring device position information 76 stored in the on-board storage unit 62 of the on-board device 30 is located on all routes on which the train travels. When the position information of the along-line monitoring device 20 is stored, the along-line monitoring device 20 and the on-vehicle device 30 are compared by comparing the train position information 68 and the monitoring device position information 76 stored in the on-vehicle storage unit 62. It is also possible to detect the approach of the.

  When the on-board receiving unit 66 of the on-vehicle device 30 receives the line information, the display unit 64 issues a warning to the train crew when it is determined that the line information is equal to or higher than a predetermined risk level. . Depending on the type of equipment along the road ahead, it is possible to display, for example, “25-meter wind speed danger” or “hazardous rainfall 50 mm or more danger”, or “front-fall rockfall”. Good. Although only the display unit 64 is shown in FIG. 2, a warning may be issued to the crew by a device that sounds a warning.

  The along-line monitoring device 20 periodically transmits the monitoring device position information 84 of the along-line monitoring device 20 through the along-line monitoring transmission / reception unit 86, and the on-board device 30 transmits the monitoring device position information of the along-line monitoring device through the on-vehicle transmission / reception unit 66. 84, the on-board control unit 67 shows the current position of the train stored in the on-board storage unit 62 and the monitoring device position information 84 of the along-line monitoring device 20 received by the on-board transmission / reception unit 66. When it is determined that the vehicle has approached within a predetermined distance as compared with the information 68, the on-board device 30 may receive the line information.

The relay transmission / reception unit 320 relays the roadside information obtained from the roadside monitoring device 20.

  As a result, when the on-board device 30 is currently traveling from the left side to the right side of the drawing, even if communication with the along-line monitoring device 20 cannot be secured, the intermediate line relay device 300 transmits the along-line monitoring device 20. By relaying information, it is possible to communicate with an on-vehicle device 30 farther away.

  The relay device 300 periodically transmits the relay device position information 380 of the relay device 300 through the relay transmission / reception unit 320, and the on-board device 30 receives the relay device position information 380 of the relay device 300 through the on-vehicle transmission / reception unit 66. In this case, the onboard control unit 67 compares the relay device position information 380 of the relay device 300 received by the onboard transmission / reception unit 66 with the train position information 68 indicating the current position of the train stored in the onboard storage unit 62. When it is determined that the vehicle has approached within a predetermined distance, the on-board device 30 may receive relay information from the track monitoring device 20 and receive track information.

A railroad line information transmission system that performs control to switch to communication with the lineside monitoring device 20 when the unit 67 determines that it has passed the relay device 300 is shown. As a result, it is possible to acquire the railway line information with a better communication performance.

In FIG. 5, trains in which communication between the railway monitoring device 20 or the relay device 300 and the on-board devices 30 and 32 are established are trains based on the train schedule information 74 stored in the on-board storage unit 62. When it is determined that they pass each other, the on-board control unit 67 of the on-board devices 30 and 32 of both trains performs control for switching to communication between the on-board devices.

  In addition, a train in which communication between the trackside monitoring device 20 or the relay device 300 and the onboard device 32 is established, and a train in which communication between the trackside monitoring device 20 or the relay device 300 and the onboard device 30 is not established, When it is determined that the trains pass each other based on the train schedule information 74 stored in the on-board storage unit 62, the on-board control unit 67 of the on-board devices 30 and 32 of both trains establishes communication and provides information on the line A state is shown in which control is performed to transmit the line information from the received on-board device 32 to the on-board device 30 for which communication has not been established.

  FIG. 5 shows an attempt to use an on-vehicle device 30 mounted on a traveling train as a repeater. Thereby, stable communication can be performed even when the communication state between the trackside monitoring device 20 and the on-board device 30 is poor.

FIG. 6 illustrates a state in which the on-board device 32 has advanced past the along-line monitoring device 20. When the on-board device 32 is in the vicinity of the along-line monitoring device 20, it should have acquired the along-line information from the along-line monitoring device 20, and at that time, the information is stored in the on-board storage unit 62.

  FIG. 6 illustrates a situation in which the onboard equipment 30 is mounted on the oncoming train after communication between the onboard equipment 32 and the wayside monitoring equipment 20 is not established.

  In this case, the on-board device 32 transmits to the on-board device 32 the on-rail device information stored in the on-board storage unit 62 of the on-board device 32.

  As a result, the on-board device 30 can know in advance the information obtained by the preceding roadside monitoring device 20 even when communication with the roadside monitoring device 20 is still impossible.

  By transmitting the track information directly from the track status monitoring device to the train, it is possible to transmit the track information in real time and pinpoint without going through the command center, and the train also becomes a relay terminal for transmitting the track information By making it possible to use a radio instead of a wired cable, the train can become a relay terminal even if it becomes difficult for the oncoming vehicle between the trackside status monitoring device and the train to transmit the radio. In addition, it is possible to transmit information along the railway line, and in addition, if you want to add monitoring points and relay points temporarily or temporarily install them, the burden of construction has been reduced by transmitting information wirelessly instead of wired cables.
