鉄道沿線の鉄道用電気設備の現状の情報を収集する場合には、鉄道用電気設備の現状の情報を沿線に設けた子機において収集し、移動中の電車内に設置した親機に対して送信し、電車内において受信することで、大規模なネットワークシステムを組むことなく、かつ、作業員の手を介すことなく自動的に、鉄道用電気設備の現状の情報を収集することは可能になっている。(例えば特許文献1参照)。 When collecting information on the current state of electrical equipment for railways along the railway, information on the current state of electrical equipment for railways is collected in the slave units installed along the railway line, and the information is collected for the main unit installed in the moving train.

図1は、本発明に係る鉄道沿線情報伝送システム10の全体図である。図1には、沿線監視機器20、車上機器30,中央監視装置40、線路50が示されている。 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.
沿線監視機器20は、雨量、風速、落石、雪崩等を監視するために鉄道沿線に設置された監視機器である。この沿線監視機器20は、例えば、雨量計、風速計、地震計等が該当する。また、落石や雪崩の有無を判断する装置も含まれる。ただし、気象状況や自然現象のみを監視する機器には限定されず、鉄道沿線で生じた出来事を監視する機器すべてが含まれる。 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.
車上機器30は、線路50を走る列車に搭載されて列車の進行に伴って移動する。車上機器30の位置が図示されている場合には当該場所には列車が位置していることになる。今、車上機器30は図面右側に向かって移動している。この車上機器30は、沿線監視機器20に接近すると沿線監視機器20と通信を行って沿線監視機器20が得た雨量、風速、地震の震度、落石や雪崩の有無等の情報を受信する。 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. When the on-board device 30 approaches the along-line monitoring device 20, it communicates with the along-line monitoring device 20 and receives information such as rainfall, wind speed, seismic intensity, presence of falling rocks and avalanches obtained by the along-line monitoring device 20.
中央監視装置40は、管轄する区域内のすべての列車の運行を監視する。例えば線路の一区間を通過するときに電流回路が形成されることで列車の通過を検知するようにし、その場合に列車の通過情報を中央監視装置40に通知するように構成すると列車の現在位置及びある地点の通過時刻が分かる。管轄する区域内のすべての列車の運行を監視してダイヤの乱れを検知することもできる。 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.
図2は、本発明に係る鉄道沿線情報伝送システム10の内部構成図である。図2には、列車に搭載されて線路50上を移動する車上機器30と、鉄道沿線の状態を監視して得られた沿線情報を送信する沿線監視機器20とからなる鉄道沿線情報伝送システム10が図示されている。 FIG. 2 is an internal configuration diagram of the railway line information transmission system 10 according to the present invention. FIG. 2 shows a railroad track information transmission system comprising an on-board device 30 that is mounted on a train and moves on a railroad track 50, and a roadside monitoring device 20 that transmits roadside information obtained by monitoring the state of the railroad. 10 is shown.
車上機器30は、車上機器30が搭載される列車の現在位置を示す列車位置情報68、列車番号情報72、列車ダイヤ情報74及び沿線監視機器20の監視機器位置情報76を記憶する車上記憶部62と、沿線監視機器20と無線通信を行う車上送受信部66と、車上記憶部62に記憶された情報に基づいて、車上送受信部66に通信を指示する車上制御部67とを含む。 The on-board device 30 stores the train position information 68 indicating the current position of the train on which the on-board device 30 is mounted, the train number information 72, the train diagram information 74, and the monitoring device position information 76 of the along-line monitoring device 20. Based on the information stored in the storage unit 62, the on-vehicle transmission / reception unit 66 that performs wireless communication with the along-line monitoring device 20, and the on-vehicle transmission / reception unit 66 that instructs communication on the on-vehicle transmission / reception unit 66. Including.
車上記憶部62は、車上機器30が搭載される列車の現在位置を示す列車位置情報68、列車番号情報72、列車ダイヤ情報74及び沿線監視機器20の監視機器位置情報76を記憶する。列車の現在位置を示す列車位置情報68は、中央監視装置40からの情報に基づくものであってもよいし、GPSを用いて算出された位置に基づくものであってもよい。列車が走行中に自車の位置を認識できる情報であればその取得方法については任意である。例えば、鉄道に沿線に敷設されている距離標(キロポスト)を読み取って列車位置情報と認識する装置を用いることも任意である。 The on-board storage unit 62 stores train position information 68 indicating the current position of the train on which the on-board equipment 30 is mounted, train number information 72, train diagram information 74, and monitoring equipment position information 76 of the along-line monitoring equipment 20. 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.
列車番号情報72は、中央監視装置40が管轄する全列車に一意に割り振られた固有の番号である。列車ダイヤ情報74は各列車のダイヤグラムである。この列車ダイヤ情報74は、通常取り運行されていれば毎日同じものとなるのが原則であるが、臨時列車があったり、何らかの原因で遅延が生じたりすると刻々と変動するものである。従って、この列車ダイヤ情報74は、列車の運行状況を監視する中央監視装置40との通信によって更新されるのが望ましい。 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.
沿線監視機器20の監視機器位置情報76については、沿線監視機器20は固定されているので、例えば、近くのキロポストからどの程度の距離離れているかという観点から監視機器位置情報76を定めることができる。ここで、車上機器30の車上記憶部62に記憶されている監視機器位置情報76は、列車が走行する路線に位置するすべての監視機器位置情報が記憶されていることが望ましい。 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. . Here, it is desirable that the monitoring device position information 76 stored in the on-vehicle storage unit 62 of the on-vehicle device 30 stores all the monitoring device position information located on the route on which the train travels.
車上送受信部66は、沿線監視機器20と無線通信を行う。従って、車上送受信部66は無線通信機を用いて実現することができる。また、車上制御部67は、車上記憶部62に記憶された情報に基づいて、車上送受信部66に通信を指示する。 The on-vehicle transmission / reception unit 66 performs wireless communication with the along-line monitoring device 20. Therefore, the on-vehicle transmission / reception unit 66 can be realized using a wireless communication device. In addition, the on-board controller 67 instructs the on-board transmitter / receiver 66 to communicate based on the information stored in the on-board storage unit 62.
沿線監視機器20は、沿線監視機器20の監視機器位置情報84を記憶する沿線監視記憶部82と、車上機器30と無線通信を行う沿線監視送受信部86と、沿線監視記憶部82に記憶された情報に基づいて、沿線監視送受信部86に通信を指示する沿線監視制御部88とを含む。 The roadside monitoring device 20 is stored in the roadside monitoring storage unit 82 that stores the monitoring device position information 84 of the roadside monitoring device 20, the roadside monitoring transmission / reception unit 86 that performs wireless communication with the on-vehicle device 30, and the roadside monitoring storage unit 82. And a roadside monitoring control unit 88 that instructs the roadside transmission / reception unit 86 to communicate based on the received information.
沿線監視記憶部82は、沿線監視機器20の監視機器位置情報84を記憶する。沿線監視送受信部86は、車上機器30と無線通信を行う。沿線監視制御部88は、沿線監視記憶部82に記憶された情報に基づいて、沿線監視送受信部86に通信を指示する。ここで、沿線監視機器20の監視機器位置情報84は、その沿線監視機器20の位置情報であり、例えば上述したように、近くのキロポストからどの程度の距離離れているかという観点から監視機器位置情報84を定めることができる。 The along-line monitoring storage unit 82 stores monitoring device position information 84 of the along-line monitoring device 20. The along-line monitoring transmission / reception unit 86 performs wireless communication with the on-vehicle device 30. 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.
この鉄道沿線情報伝送システム10は、車上記憶部62に記憶された列車の現在位置を示す列車位置情報68と、沿線監視記憶部82に記憶された沿線監視機器20の監視機器位置情報84とに基づいて、車上機器30と沿線監視機器20とが予め定められた所定の距離以内に接近した場合に、車上制御部67と沿線監視制御部88とが車上送受信部66と沿線監視送受信部86との間の通信を確立する制御を行う。例えば、沿線監視機器20が、列車位置情報68と監視機器位置情報84とが3キロメートル以内に近づいたとときには、沿線監視機器20が収集した風量、降雪量等の情報を沿線監視送受信部86が送信するように沿線監視制御部88は指示を発するようにすることもできるし、車上機器制御部67が、沿線監視機器20に対して通信が可能である旨の信号を送信するようにしてもよい。 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.
なお、車上機器30の車上記憶部62には、上述したように車上機器30の車上記憶部62に記憶されている監視機器位置情報76は、列車が走行するすべて路線に位置する沿線監視機器20の位置情報が記憶されている場合には、車上記憶部62に記憶されている列車位置情報68と監視機器位置情報76との対比により沿線監視機器20と車上機器30との接近を検地するようにすることも可能である。 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.
表示部64は、車上機器30の車上受信部66が沿線情報を受信した場合に沿線情報が所定の危険度以上であると判断される場合には、列車乗務員に警報を発するものである。前方の沿線機器の種類に応じて、例えば、「風速25メートル危険」「降雨量50ミリメートル以上危険」などのような表示をすることが可能であるし、「前方落石あり」のような表示でもよい。なお、図2には表示部64のみ示したが、警報を鳴らす装置によって乗務員に警報を発するものであってもよい。 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.
また、沿線監視機器20は、沿線監視送受信部86を通じて定期的に沿線監視機器20の監視機器位置情報84を送信し、車上機器30は車上送受信部66を通じて沿線監視機器の監視機器位置情報84を受信した場合に、車上制御部67が、車上送受信部66が受信した沿線監視機器20の監視機器位置情報84と車上記憶部62に記憶された列車の現在位置を示す列車位置情報68と比較して予め定められた所定の距離以内に接近したと判断した場合に、車上機器30が沿線情報を受信するようにしてもよい。 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.
図3は、本発明の他の実施形態に係る鉄道沿線情報伝送システム10の構成図である。図1及び図2と同一の符号は同一の内容であるためその説明は省略する。図3には、車上機器30と沿線監視機器20と、車上機器30と中央監視装置40の他に中継機器300が図示されている。 FIG. 3 is a configuration diagram of a railway line information transmission system 10 according to another embodiment of the present invention. Since the same reference numerals as those in FIGS. 1 and 2 have the same contents, the description thereof is omitted. In FIG. 3, a relay device 300 is illustrated in addition to the on-vehicle device 30, the along-line monitoring device 20, the on-vehicle device 30 and the central monitoring device 40.
中継機器300は、中継機器300の中継機器位置情報380を記憶する中継記憶部360と、車上機器30及び沿線監視機器20と無線通信を行う中継送受信部320と、中継記憶部360に記憶された情報に基づいて、中継送受信部320に通信を指示する中継制御部340とを含む。 The relay device 300 is stored in the relay storage unit 360 that stores the relay device position information 380 of the relay device 300, the relay transmission / reception unit 320 that performs wireless communication with the on-vehicle device 30 and the along-line monitoring device 20, and the relay storage unit 360. And a relay control unit 340 that instructs the relay transmitting / receiving unit 320 to perform communication based on the received information.
そして、車上記憶部62に記憶された列車の現在位置を示す列車位置情報68と、中継記憶部360に記憶された中継機器300の中継機器位置情報380とに基づいて、車上機器30と中継機器300とが予め定められた所定の距離以内に接近した場合に、車上制御部67と中継機器300とが車上送受信部66と中継送受信部320との間の通信を確立する制御を行い、中継送受信部320は沿線監視機器20から得られた沿線情報を中継する。 Based on the train position information 68 indicating the current position of the train stored in the on-board storage unit 62 and the relay device position information 380 of the relay device 300 stored in the relay storage unit 360, When the relay device 300 approaches within a predetermined distance, the on-board control unit 67 and the relay device 300 perform control to establish communication between the on-board transmission / reception unit 66 and the relay transmission / reception unit 320. The relay transmission / reception unit 320 relays the roadside information obtained from the roadside monitoring device 20.
これにより、車上機器30が、今、図面左側から右側に走行している場合に、沿線監視機器20との間で通信が確保できない場合でも途中の中継器300が沿線監視機器20が送信する情報を中継することでより遠くの車上機器30と通信が行える。 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.
また、中継機器300は、中継送受信部320を通じて定期的に中継機器300の中継機器位置情報380を送信し、車上機器30は車上送受信部66を通じて中継機器300の中継機器位置情報380を受信した場合に、車上制御部67が、車上送受信部66が受信した中継機器300の中継機器位置情報380と車上記憶部62に記憶された列車の現在位置を示す列車位置情報68と比較して予め定められた所定の距離以内に接近したと判断した場合に、車上機器30が沿線監視機器20からの中継を受信して沿線情報を受信するようにしてもよい。 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.
図4は、本発明の他の実施形態に係る鉄道沿線情報伝送システム10の構成図である。図1から図3と同一符号は同一の意味である。図4には、車上送受信部66が受信した中継機器300の中継機器位置情報380と、車上記憶部62に記憶された列車の現在位置の列車位置情報68とに基づいて、車上制御部67が中継機器300を通り過ぎたと判断した場合には沿線監視機器20との通信に切り替える制御を行う鉄道沿線情報伝送システムが示されている。これにより、より通信性能のよい状態で沿線情報を取得することができる。 FIG. 4 is a configuration diagram of a railway line information transmission system 10 according to another embodiment of the present invention. 1 to 3 have the same meaning. In FIG. 4, on-vehicle control is performed based on the relay device position information 380 of the relay device 300 received by the on-vehicle transmission / reception unit 66 and the train position information 68 of the current position of the train stored in the on-vehicle storage unit 62. 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.
図5は、本発明の他の実施形態に係る鉄道沿線情報伝送システム10の構成図である。図1から図4と同一符号は同一の意味である。図5には、沿線監視機器20又は中継機器300と車上機器30、32との通信が確立されている列車同士が、車上記憶部62に記憶された列車ダイヤ情報74に基づいて列車がすれ違うと判断される場合、両列車の車上機器30、32の車上制御部67が、車上機器同士での通信に切り替える制御を行う様子が図示されている。 FIG. 5 is a configuration diagram of a railway line information transmission system 10 according to another embodiment of the present invention. 1 to 4 have the same meaning. 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.
また、沿線監視機器20又は中継機器300と車上機器32との通信が確立されている列車と沿線監視機器20又は中継機器300と車上機器30との通信が確立されていない列車とが、車上記憶部62に記憶された列車ダイヤ情報74に基づいて列車がすれ違うと判断される場合、両列車の車上機器30、32の車上制御部67が、通信が確立されて沿線情報を受信した車上機器32から通信が確立されていない車上機器30に沿線情報を送信する制御を行う様子が図示されている。 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.
図5は走行している列車に搭載されている車上機器30を中継器として使用しようとするものである。これにより、沿線監視機器20と車上機器30との通信状態が悪い場合であっても安定した通信を行うことができる。 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.
図6は、本発明に係る第二の実施形態である通信回線構成装置の具体的な構成を示したブロック図である。図6は車上機器32が沿線監視機器20を通り過ぎて進行した状態が図示されている。この車上機器32は沿線監視機器20に近傍にいた場合には沿線監視機器20から沿線情報を取得したはずであるので、その際に、車上記憶部62にその情報を保持する。 FIG. 6 is a block diagram showing a specific configuration of the communication line configuration apparatus according to the second embodiment of the present invention. 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.
そして、図6には、車上機器32と沿線監視機器20との通信が確立されなくなった後に対向列車に搭載された車上機器30とすれ違う様子が図示されている。 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.
この場合、車上機器32は車上機器30に対して、車上機器32の車上記憶部62に格納している保持された沿線情報を車上機器32に対して送信する。 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.
これにより、車上機器30は、まだ沿線監視機器20との通信が不可能な状態であっても、前方の沿線監視機器20が得た情報を事前に知ることができる。 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.
沿線状況監視機器から列車に直接、沿線情報を伝送することで、指令所を介さずにリアルタイムかつピンポイントな沿線情報の伝送が可能になり、また、列車も沿線情報の伝送の中継端末となることが可能にすることで、有線ケーブルではなく無線を採用したことにより、沿線状況監視機器と列車との間の対向車両により無線が伝送されにくくなった場合においても、列車が中継端末となることで、沿線情報の伝送が可能にし、さらに、監視地点及び中継地点を増設や一時的に仮設したい場合において、有線ケーブルではなく無線により情報伝達を行うことにより、工事の負担が軽減したので、鉄道による輸送業界での利用が見込まれる。 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. Is expected to be used in the transportation industry.
