Description

この発明は、列車が走行する軌道に設けられた踏切の警報制御を行う踏切保安装置、特に踏切警報時間の短縮化に関するものである。   The present invention relates to a railroad crossing safety device that performs a railroad crossing warning control provided on a track on which a train travels, and more particularly to a reduction in a railroad crossing warning time.

列車が走行する軌道に設けた踏切の制御において、踏切警報機等の警報を開始してから列車の先頭が踏切に到達するまでの時間である警報時間は、列車の運転曲線から十分に踏切を遮断する時間が確保できる地点を警報開始点とし、警報開始点から踏切までの距離を最小時間で走行する時間により求められる。この最小到達時間は、図５に示すように、区間最高速度から求められる。   In the control of railroad crossings provided on the tracks on which the train runs, the alarm time, which is the time from the start of a railroad crossing alarm, etc. until the top of the train reaches the railroad crossing, is sufficiently determined from the train operation curve. The point where the time for blocking can be secured is set as the alarm start point, and the distance from the alarm start point to the railroad crossing is obtained from the time required for traveling in the minimum time. This minimum arrival time is obtained from the section maximum speed as shown in FIG.

そして例えば２組の踏切遮断機がある場合、図６に示すように、警報を開始してから７秒後に進入側の遮断動作を開始し、その後、７秒後に進入側の遮断動作を終了し、進出側の遮断動作を開始し、７秒後に進出側の遮断動作を終了してから２０秒後に列車が踏切に到着することを標準とし、進出側の遮断動作を終了してから列車が踏切に到着するまでの時間は１５秒以上であることが必要とされ、標準警報時間として４１秒、最小警報時間として３６秒が確保できるように警報時間を定めるようにしている。   For example, when there are two sets of level crossing barriers, as shown in FIG. 6, the entrance side shut-off operation is started 7 seconds after the alarm is started, and then the entrance side shut-off operation is terminated after 7 seconds. The start of the advancing side shut-off operation, 7 seconds later, after the advancing side shut-off operation is completed, the train arrives at the railroad crossing 20 seconds later, and after the advancing side shut-off operation ends, the train crosses the railroad crossing It is necessary that the time until arrival at the time is 15 seconds or more, and the alarm time is determined so that 41 seconds can be secured as the standard alarm time and 36 seconds can be secured as the minimum alarm time.

この警報時間の適正化を図り、歩行者や自動車の交通渋滞を防止するため、図５に示すように、例えば急行と緩行の列車種別によって警報開始点の位置を変えたり、あるいは列車の速度を車軸検知器により計測し、列車の速度に応じて警報開始の位置や時機を制御したり、例えば特許文献１に示すように、踏切を中心にして線路を挟んで平行に２本の漏洩伝送路を敷設し、一方の漏洩伝送路からスペクトル拡散信号を放射し、他方の漏洩伝送路で放射されたスペクトル拡散信号を受信し、受信したスペクトル拡散信号により一定の間隔で列車の存在を検知し、この検知結果を距離方向に順番に並べてメモリに蓄積し、蓄積された一連のデータから列車の位置と走行速度等を判定し、判定した列車の位置と速度に基づいて踏切制御の最適時機を算出したりして踏切遮断時間の適正化を図っている。   In order to optimize the warning time and prevent traffic congestion of pedestrians and cars, as shown in FIG. 5, for example, the position of the warning start point is changed depending on the type of express train and slow train, or the speed of the train is changed. Measured by the axle detector, controls the alarm start position and timing according to the speed of the train. For example, as shown in Patent Document 1, two leaky transmission lines are parallel to each other with the railroad track as the center. , Radiate a spread spectrum signal from one leaky transmission line, receive a spread spectrum signal radiated from the other leaky transmission line, detect the presence of a train at regular intervals by the received spread spectrum signal, The detection results are arranged in order in the distance direction and stored in the memory, the train position and traveling speed are determined from the accumulated series of data, and the optimal timing for crossing control is determined based on the determined train position and speed. In and out we are working to optimize the level crossing cut-off time.

しかしながらラッシュ時間帯など運行パターン上、列車を低速で運行している場合は、列車種別により警報開始点の位置を変えたり、車軸検知器等で列車速度を計測して踏切遮断時間の適正化を図っても、ラッシュ時間帯など運行パターン上、列車を低速で運行している場合には、踏切遮断時間を適正にすることは困難であった。   However, if the train is operating at low speed due to operation patterns such as rush hours, the location of the alarm start point may be changed depending on the train type, or the train speed may be measured with an axle detector, etc. Even if it is planned, due to operation patterns such as rush hours, it is difficult to make the level crossing interruption time appropriate when the train is operating at a low speed.

この問題を解消するため、車軸検知器を踏切制御範囲内に多数設置し、列車速度をきめ細かく検出して踏切遮断時間の適正化を図ると、路線上に多数の踏切がある場合、車軸検知器の設置に膨大な費用が必要になってしまう。   To solve this problem, install many axle detectors within the level crossing control range, detect the train speeds finely, and optimize the level crossing cutoff time. If there are many level crossings on the route, the axle detector A huge amount of money will be required for installation.

また、特許文献１に示すように、線路を挟んで漏洩伝送路を敷設し、漏洩伝送路間の信号の授受により列車の位置と走行速度を求める方法も、設備に多くの費用を必要とするとともに、求めた列車の走行速度から区間最高速度になるように、その区間の最大加速度で加速して走行すると仮定して警報時間を決定しているため、列車の実際の走行速度に最も適した警報時間を決定することは困難であるという短所がある。
特開２００３−５４４１号公報 Moreover, as shown in Patent Document 1, a method of laying a leaky transmission line across a line and obtaining a train position and traveling speed by exchanging signals between the leaky transmission lines also requires a large amount of equipment. At the same time, the warning time is determined on the assumption that the vehicle is accelerated at the maximum acceleration of the section so that the train's traveling speed is the maximum speed, so it is most suitable for the actual traveling speed of the train. There is a disadvantage that it is difficult to determine the alarm time.
Japanese Patent Laid-Open No. 2003-5441

図１はこの発明の踏切保安装置の構成を示すブロック図である。図に示すように、踏切１において列車の運転と道路交通との間の安全を保つ踏切保安装置は、各軌道回路１Ｔ〜ｎＴの境界に接続され、各軌道回路１Ｔ〜ｎＴに列車２が在線することを検知するとともに、ＬＡＮ３から入力する先行列車の走行位置に応じて後続する軌道回路毎のＡＴＣコードを作成して各軌道回路１Ｔ〜ｎＴに伝送するＡＴＣ／ＴＤ地上装置４ａ〜４ｎと、運行管理装置５と運行パターン設定部６と踏切警報機や踏切遮断機等の踏切制御器７の動作を制御する踏切制御装置８を有する。運行管理装置５は、線区内を走行する多数の列車の進路制御や列車ダイヤを管理する。運行パターン設定部６は、運行管理装置５で管理する列車ダイヤに応じた運行パターンをリアルタイムで設定する。 FIG. 1 is a block diagram showing the structure of a railroad crossing safety device according to the present invention. As shown in the figure, a railroad crossing safety device that maintains safety between train operation and road traffic at a railroad crossing 1 is connected to the boundary of each track circuit 1T to nT, and a train 2 is present on each track circuit 1T to nT. thereby detecting that the ATC / TD ground device 4a~4n transmitting by creating ATC code for each subsequent track circuit in accordance with the traveling position of the preceding train input from LAN3 each track circuit 1T～nT, It has a crossing control device 8 that controls the operation of the crossing controller 7 such as a crossing alarm device, a crossing breaker, etc. The operation management device 5 manages the route control and train schedule of a large number of trains traveling in the line section. The operation pattern setting unit 6 sets an operation pattern corresponding to the train schedule managed by the operation management device 5 in real time.

踏切制御装置８は、図２のブロック図に示すように、運行パターン入力部９と列車位置情報入力部１０と警報開始点決定部１１と速度制御情報発生部１２と速度制御情報出力部１３と警報信号発生部１４及び警報信号出力部１５を有する。運行パターン入力部８は運行パターン設定部６で設定した運行パターンを入力する。列車位置情報入力部１０は各ＡＴＣ／ＴＤ地上装置４ａ〜４ｎから列車位置情報を入力する。警報開始点決定部１１は運行パターン入力部９で入力した運行パターンに即した運転曲線と所定の踏切警報時間から警報開始点となる軌道回路を決定する。速度制御情報発生部１２は警報開始点となる軌道回路を決定したときの運行パターンに応じた速度制限情報を軌道回路１Ｔ〜ｎＴ毎に発生する。速度制御情報出力部１３は発生した速度制限情報を各軌道回路１Ｔ〜ｎＴに接続されたＡＴＣ／ＴＤ地上装置４ａ〜４ｎに送る。警報信号発生部１４は列車位置情報入力部１０で入力している列車位置情報により列車２が警報開始点と決定した軌道回路に進入したことを検知すると警報信号を発生する。警報信号出力部１５は発生した警報信号を踏切制御器７に送り踏切制御を開始させる。   As shown in the block diagram of FIG. 2, the railroad crossing control device 8 includes an operation pattern input unit 9, a train position information input unit 10, an alarm start point determination unit 11, a speed control information generation unit 12, and a speed control information output unit 13. An alarm signal generator 14 and an alarm signal output unit 15 are provided. The operation pattern input unit 8 inputs the operation pattern set by the operation pattern setting unit 6. Train position information input unit 10 inputs train position information from each ATC / TD ground device 4a-4n. The alarm start point determination unit 11 determines a track circuit serving as an alarm start point from an operation curve according to the operation pattern input by the operation pattern input unit 9 and a predetermined level crossing alarm time. The speed control information generating unit 12 generates speed limit information corresponding to the operation pattern when the track circuit serving as the alarm start point is determined for each track circuit 1T to nT. The speed control information output unit 13 sends the generated speed limit information to the ATC / TD ground devices 4a to 4n connected to the track circuits 1T to nT. The alarm signal generator 14 generates an alarm signal when it detects that the train 2 has entered the track circuit determined as the alarm start point based on the train position information input by the train position information input unit 10. The warning signal output unit 15 sends the generated warning signal to the level crossing controller 7 to start the level crossing control.

この踏切制御装置８による踏切制御を図３のフローチャートと図４の模式図を参照して説明する。   The level crossing control by the level crossing control device 8 will be described with reference to the flowchart of FIG. 3 and the schematic diagram of FIG.

運行パターン設定部６は、運行管理装置５で管理する列車ダイヤに応じた運行パターンをリアルタイムで設定し、設定した運行パターンを踏切制御装置８に送る。踏切制御装置８の運行パターン入力部９は送られた運行パターンを入力して警報開始点決定部１１に送る（ステップＳ１）。警報開始点決定部１１は送られた運行パターンに応じた運転曲線と踏切警報時間から警報開始点となる軌道回路を決定する（ステップＳ２）。例えば図４（ａ）に示すように、運行パターン１６ａで指定した各軌道回路１Ｔ〜１０Ｔが８０信号のときは、列車２が許容最高速度である８０ｋｍ／ｈで例えば標準警報時間４１秒だけ走行した場合の踏切制御距離を算出し、算出した踏切制御距離と各軌道回路１Ｔ〜７Ｔの列車進入側から踏切１までの距離から警報開始点となる軌道回路１Ｔを決定する。また、図４（ｂ）に示すように、運行パターン１６ｂで指定した各軌道回路１Ｔ〜１０Ｔが４０信号のときは、列車２が許容最高速度である４０ｋｍ／ｈで例えば標準警報時間４１秒だけ走行した場合の踏切制御距離を算出し、算出した踏切制御距離と各軌道回路１Ｔ〜７Ｔの列車進入側から踏切１までの距離から警報開始点となる軌道回路４Ｔを決定する。さらに、図４（ｃ）に示すように、運行パターン１６ｃで指定した各軌道回路１Ｔ〜１０Ｔが６０信号のときは、列車２が許容最高速度である６０ｋｍ／ｈで例えば標準警報時間４１秒だけ走行した場合の踏切制御距離を算出し、算出した踏切制御距離と各軌道回路１Ｔ〜７Ｔの列車進入側から踏切１までの距離から警報開始点となる軌道回路３Ｔを決定する。この決定した警報開始点となる軌道回路を速度制御情報発生部１２と警報信号発生部１４に送る。   The operation pattern setting unit 6 sets an operation pattern corresponding to the train schedule managed by the operation management device 5 in real time, and sends the set operation pattern to the railroad crossing control device 8. The operation pattern input unit 9 of the level crossing control device 8 inputs the transmitted operation pattern and sends it to the alarm start point determination unit 11 (step S1). The alarm start point determination unit 11 determines a track circuit serving as an alarm start point from the operation curve corresponding to the sent operation pattern and the level crossing alarm time (step S2). For example, as shown in FIG. 4A, when each track circuit 1T to 10T specified by the operation pattern 16a has 80 signals, the train 2 travels at an allowable maximum speed of 80 km / h, for example, for a standard alarm time of 41 seconds. The crossing control distance in this case is calculated, and the track circuit 1T serving as an alarm start point is determined from the calculated crossing control distance and the distance from the train approach side to the crossing 1 of each track circuit 1T to 7T. Further, as shown in FIG. 4B, when each track circuit 1T to 10T specified by the operation pattern 16b has 40 signals, the train 2 has an allowable maximum speed of 40 km / h, for example, only a standard alarm time of 41 seconds. The railroad crossing control distance when the vehicle travels is calculated, and the track circuit 4T serving as the alarm start point is determined from the calculated railroad crossing control distance and the distance from the train approach side to the railroad crossing 1 of each track circuit 1T to 7T. Furthermore, as shown in FIG. 4 (c), when each track circuit 1T to 10T specified by the operation pattern 16c has 60 signals, the train 2 is at a maximum allowable speed of 60 km / h, for example, only a standard alarm time of 41 seconds. A railroad crossing control distance when traveling is calculated, and the track circuit 3T serving as an alarm start point is determined from the calculated railroad crossing control distance and the distance from the train approach side to the railroad crossing 1 of each of the track circuits 1T to 7T. The track circuit serving as the determined alarm start point is sent to the speed control information generator 12 and the alarm signal generator 14.

速度制御情報発生部１２は、警報開始点となる軌道回路を決定したときの運行パターン、例えば図４（ｂ）に示すように軌道回路４Ｔの列車進入側を警報開始点と決定した場合は、運行パターン１６ｂの４０信号に応じた速度制御情報を軌道回路１Ｔ〜ｎＴ毎に発生して速度制御情報出力部１３に送る。速度制御情報出力部１３は送られた速度制御情報を各軌道回路１Ｔ〜ｎＴに接続されたＡＴＣ／ＴＤ地上装置４ａ〜４ｎに送る（ステップＳ３）。ＡＴＣ／ＴＤ地上装置４ａ〜４ｎは送られた速度制御情報によりＡＴＣコードを作成して各軌道回路１Ｔ〜ｎＴに伝送して列車２の速度を制御する。   When the speed control information generating unit 12 determines the operation pattern when the track circuit serving as the alarm start point is determined, for example, the train approach side of the track circuit 4T as illustrated in FIG. Speed control information corresponding to 40 signals of the operation pattern 16b is generated for each track circuit 1T to nT and sent to the speed control information output unit 13. The speed control information output unit 13 sends the sent speed control information to the ATC / TD ground devices 4a to 4n connected to the track circuits 1T to nT (step S3). The ATC / TD ground devices 4a to 4n create ATC codes based on the sent speed control information and transmit them to the track circuits 1T to nT to control the speed of the train 2.

警報信号発生部１４は、列車位置情報入力部１０で入力している列車位置情報により列車２が警報開始点と決定した軌道回路に進入したことを検知すると（ステップＳ４）、警報信号を発生して警報信号出力部１５に送る。警報信号出力部１５は送られた警報信号を踏切制御器５に送り、踏切制御を開始させる（ステップＳ５）。この状態で警報信号発生部１２は列車位置情報入力部８で入力した列車位置情報により列車２が踏切１の警報終止点を通過したことを検知すると（ステップＳ６，Ｓ７）、警報信号を解除して警報信号出力部１５を介して踏切制御器７に送り踏切制御を終了させる（ステップＳ８）。   When the alarm signal generator 14 detects that the train 2 has entered the track circuit determined as the alarm start point based on the train position information input by the train position information input unit 10 (step S4), the alarm signal generator 14 generates an alarm signal. To the alarm signal output unit 15. The warning signal output unit 15 sends the sent warning signal to the crossing controller 5 to start crossing control (step S5). In this state, when the alarm signal generator 12 detects that the train 2 has passed the alarm end point of the crossing 1 based on the train position information input by the train position information input unit 8 (steps S6 and S7), the alarm signal is canceled. Then, the crossing control is terminated by the crossing controller 7 via the warning signal output unit 15 (step S8).

この踏切制御処理を運行パターン設定部６から送られる運行パターンが変更するたびに繰り返す。   This level crossing control process is repeated every time the operation pattern sent from the operation pattern setting unit 6 changes.

このように列車２の運行パターンにより警報開始点を変えるとともに、各警報開始点を決定したときの運行パターンにより列車２の速度を制御するから列車２の実際の走行速度に最も適した踏切警報時間を決定して踏切遮断時間の適正化を図ることができる。   In this way, the alarm start point is changed according to the operation pattern of the train 2, and the speed of the train 2 is controlled by the operation pattern when each alarm start point is determined, so the level crossing alarm time most suitable for the actual traveling speed of the train 2 It is possible to optimize the level crossing interruption time.

また、列車ダイヤに応じた運行パターンにより警報開始点を決定するから、既存の設備を利用することができ、設置費用を大幅に低減することができる。   Moreover, since the alarm start point is determined by the operation pattern according to the train schedule, existing facilities can be used, and the installation cost can be greatly reduced.
