Description

この発明は、道路とレールの両方を走行できる車両を利用したデュアルモード・トランスポート・システムにおける踏切制御装置、特に踏切制御の信頼性の向上と設備の簡易化に関するものである。   The present invention relates to a crossing control device in a dual mode transport system using a vehicle capable of traveling on both roads and rails, and more particularly to improvement in reliability of crossing control and simplification of equipment.

デュアルモード・トランスポート・システムは、特許文献１に示すように、道路と、道路に連結されたレールを有する軌道の両方を走行するゴムタイヤ駆動システムである。このシステムの地上設備としては、図４に示すように、道路１５とレール２及び道路１５からレール２とレール２から道路１５の走行モードを変換するモード変換領域１６を有する。この道路１５とレール２の両方を走行する車両１は、図５に示すように、一般のバスと同様に、前後に設けられたゴムタイヤの車輪１７，１８と、レール２に係合する前ガイド輪１９及び後ガイド輪２０を有する。後の車輪１８は、図６（ａ）に示すように、駆動軸２１に連結され、道路１５とレール２上で駆動力を与える駆動輪１８ａと、道路１５にだけ接する外輪１８ｂとを有し、前の車輪１７は、図６（ｂ）に示すように、レール２には接しないように前ガイド輪１９よりは外側に配置されている。   As shown in Patent Document 1, the dual mode transport system is a rubber tire drive system that travels on both a road and a track having a rail connected to the road. As shown in FIG. 4, the ground equipment of this system includes a road 15 and a rail 2, and a mode conversion area 16 that converts a travel mode of the road 15 from the road 15 to the rail 2 and the rail 2. As shown in FIG. 5, the vehicle 1 that travels on both the road 15 and the rail 2 has rubber tire wheels 17 and 18 provided at the front and rear, and a front guide that engages with the rail 2, as in a general bus. It has a wheel 19 and a rear guide wheel 20. As shown in FIG. 6A, the rear wheel 18 includes a driving wheel 18 a that is connected to the driving shaft 21 and applies driving force on the road 15 and the rail 2, and an outer wheel 18 b that contacts only the road 15. As shown in FIG. 6B, the front wheel 17 is disposed outside the front guide wheel 19 so as not to contact the rail 2.

この車両１は、道路１５上では一般のバスと同様にゴムタイヤの車輪１７，１８により走行し、レール２上では前ガイド輪１９と後ガイド輪２０によりレール２に沿って案内しながら後の駆動輪１８ａにより走行する。また、道路１５からレール２への変換は、モード変換領域１６で前後のガイド輪１９，２０を油圧で下降させてレール２に係合させ、前の車輪１７を引き上げてレール走行状態にする。レール２から道路１５への変換は前の車輪１７を下降させて前後のガイド輪１９，２０を引き上げて道路走行状態にする。   The vehicle 1 travels on the road 15 by wheels 17 and 18 of rubber tires like a general bus, and on the rail 2 is driven along the rail 2 by the front guide wheel 19 and the rear guide wheel 20 and drives behind. Travel by wheel 18a. Further, in the conversion from the road 15 to the rail 2, the front and rear guide wheels 19 and 20 are lowered by hydraulic pressure in the mode conversion area 16 and engaged with the rail 2, and the front wheel 17 is pulled up to be in the rail running state. In the conversion from the rail 2 to the road 15, the front wheel 17 is lowered and the front and rear guide wheels 19 and 20 are pulled up to be in a road running state.

このデュアルモード・トランスポート・システムにおいては、車軸によるレール短絡が不安定であるため、踏切制御のための車両検知に従来の軌道回路方式を利用した踏切制御子を使用することができず、新しい方式の踏切制御装置の導入が要望されている。
特開２００５−６７５９２号公報 In this dual-mode transport system, the rail short circuit caused by the axle is unstable, so it is not possible to use a conventional level crossing controller using a track circuit system for vehicle detection for level crossing control. There is a demand for the introduction of a level crossing control device.
JP 2005-67592 A

この発明は、この要望を満たすためになされたものであり、デュアルモード・トランスポート・システムにおいて踏切に進入する車両を確実に検知して踏切制御の信頼性を高めると共に、低コストで容易に施工することができる踏切制御装置を提供することを目的とするものである。   The present invention has been made to satisfy this demand. In the dual mode transport system, the vehicle entering the railroad crossing is reliably detected to increase the reliability of the rail crossing control, and can be easily installed at low cost. An object of the present invention is to provide a railroad crossing control device that can be used.

この発明の踏切制御装置は、直流送電部と車軸検知器と踏切始動制御部と受電部と受信器及び制御部を有し、直流送電部は車両が進行するレールを有する軌道の踏切始動点でレールに直流信号を送り出し、車軸検知器は踏切始動点の列車進入側に設けられ、車両の車軸を検知して車軸検知信号を出力し、踏切始動制御部は車軸検知器から車軸検知信号を入力したときに、直流送電部からレールに送っている直流信号を遮断し、受電部は踏切の近傍に設けられ、直流送電部がレールに送っている直流信号を受電し、受信器は踏切より車両進出側に設けられた地上子が車両に搭載した車上子と電磁結合したときの信号を受信し、制御部は、受電部で受電しているレールからの直流信号が遮断したとき、車両が踏切始動点に接近したと判断して踏切制御を開始し、受信器で車両からの信号を受信したときに、車両が踏切を通過したと判断して踏切制御を終了することを特徴とする。 The railroad crossing control device of the present invention includes a DC power transmission unit, an axle detector, a railroad crossing start control unit, a power reception unit, a receiver, and a control unit, and the DC power transmission unit is a railroad crossing start point having a rail on which the vehicle travels. A DC signal is sent to the rail, the axle detector is installed on the train entry side of the railroad crossing start point, detects the vehicle axle and outputs the axle detection signal , and the railroad crossing start control unit inputs the axle detection signal from the axle detector The DC signal sent from the DC power transmission unit to the rail is cut off, the power reception unit is provided near the railroad crossing, the DC power transmission unit receives the DC signal sent to the rail, and the receiver is the vehicle from the railroad crossing. When the ground unit provided on the advancing side is electromagnetically coupled with the vehicle upper unit mounted on the vehicle, the control unit receives the signal when the DC signal from the rail receiving power is cut off. A railroad crossing is judged to have approached the railroad crossing starting point Start the control, when it receives a signal from the vehicle at the receiver, the vehicle is characterized in that it is determined to have passed the crossing ends the railroad crossing control.

この発明は、車両が進行するレールを有する軌道の踏切始動点で直流送電部から、常時レールに直流信号を送り出し、踏切始動点の列車進入側に設けた車軸検知器で列車の車軸を検知したときに、直流送電部から送り出している直流信号を遮断し、このレールに送り出している直流信号の有無を踏切の近傍に設けた受電部で受電することにより、車軸によるレール短絡が不安定なデュアルモード・トランスポート・システムにおいても踏切始動点に車両が接近したことを簡単な構成で確実に検知することができる。   In the present invention, a DC signal is always sent from a DC power transmission unit to a rail at a railroad crossing starting point of a track having a rail on which the vehicle travels, and a train axle is detected by an axle detector provided on the train entrance side of the railroad crossing starting point. Sometimes, the DC signal sent from the DC power transmission unit is cut off, and the presence or absence of the DC signal sent to this rail is received by the power receiving unit provided near the railroad crossing so that the rail short circuit due to the axle is unstable. Even in the mode transport system, it is possible to reliably detect that the vehicle has approached the crossing starting point with a simple configuration.

また、踏切より車両進出側に設けられた地上子が車両に搭載した車上子と電磁結合したとき、車両が踏切を進出したと判断するから、車両が踏切警報区間から進出したことを確実に検知することができる。   In addition, when the ground element provided on the vehicle advance side from the level crossing is electromagnetically coupled with the vehicle upper part mounted on the vehicle, it is determined that the vehicle has advanced the level crossing, so it is ensured that the vehicle has advanced from the level crossing warning section.

For example, in a dual mode transport system using a vehicle capable of traveling on both roads and rails, the railroad crossing control device is a railroad crossing starting point that is a suitable distance before the railroad crossing 3 having the rail 2 on which the vehicle 1 travels. A DC power transmission unit 5 is connected to the left and right rails 2 via a resistor 4, and an axle detector 7 connected to the level crossing start control unit 6 is provided on the approach side of the level crossing start point. The railroad crossing start control unit 6 controls the operation of the vehicle approach detection relay ART based on whether or not the vehicle 1 is detected by the axle detector 7, and is connected to the DC power source 9 via the voltage conversion unit 8. 7, the coil of the vehicle approach detection relay ART is excited when the axle of the vehicle 1 is not detected, and the coil of the vehicle approach detection relay ART is de-energized when the axle detector 7 detects the axle of the vehicle 1. The DC power transmission unit 5 sends a DC current to the rail 2 and is connected to the DC power source 9 via the operation contact ART of the vehicle approach detection relay ART. An ATS ground unit 11 connected to the receiver 10 is provided on the vehicle advance side of the railroad crossing 3, and a power receiving unit 12 that receives a DC current sent from the DC power transmitting unit 7 is connected to the left and right rails 2. . The receiver 10 and the power receiving unit 11 are connected to the control unit 13.

制御部１３には、図２の回路構成図に示すように、車両検知リレーＡＲＴＰと進出検知リレーＥＸＲと警報リレーＳＲと緩動緩放リレーＳＬＲと警報停止保持リレーＣＳＲ及び警報制御リレーＲを有する。車両検知リレーＡＲＴＰは受電部１１に接続され、受電部１１で直流送電部７からレール２に送られた直流電流を受電しているときに動作し、受電部１１でレール２から直流電流を受電しないときに復旧する。進出検知リレーＥＸＲは受信器１０に接続され、ＡＴＳ地上子１１が車両１に搭載したＡＴＳ車上子１２と電磁結合したときに動作する。警報リレーＳＲはコイルが常時励磁されて動作しており、車両検知リレーＡＲＴＰが復旧したときにコイルが非励磁になり復旧し、車両検知リレーＡＲＴＰが動作して警報停止保持リレーＣＳＲが動作したときに動作して自己保持する。緩動緩放リレーＳＬＲは警報停止保持リレーＣＳＲが動作したときに直ちに警報リレーＳＲが動作することを防ぐために設けられている。警報停止保持リレーＣＳＲは進出検知リレーＥＸＲが動作したときにコイルが励磁され動作して自己保持し、警報リレーＳＲと緩動緩放リレーＳＬＲの両方が復旧したときにコイルが非励磁になる。警報制御リレーＲはコイルが常時励磁され動作して、警報リレーＳＲが復旧したときにコイルが非励磁になり、踏切警報信号を出力し、警報停止保持リレーＣＳＲが動作したときに動作して踏切警報信号の出力を停止する。   As shown in the circuit configuration diagram of FIG. 2, the control unit 13 includes a vehicle detection relay ARTP, an advance detection relay EXR, an alarm relay SR, a slow / relaxation release relay SLR, an alarm stop holding relay CSR, and an alarm control relay R. . The vehicle detection relay ARTP is connected to the power reception unit 11 and operates when the power reception unit 11 receives a DC current sent from the DC power transmission unit 7 to the rail 2. The power reception unit 11 receives a DC current from the rail 2. Recover when not. The advance detection relay EXR is connected to the receiver 10 and operates when the ATS ground element 11 is electromagnetically coupled to the ATS vehicle upper element 12 mounted on the vehicle 1. The alarm relay SR operates when the coil is always excited. When the vehicle detection relay ARTP is restored, the coil is de-energized and restored, and when the vehicle detection relay ARTP is activated and the alarm stop holding relay CSR is activated. Work to self-hold. The slow / relaxed release relay SLR is provided to prevent the alarm relay SR from operating immediately when the alarm stop holding relay CSR operates. In the alarm stop holding relay CSR, when the advance detection relay EXR operates, the coil is energized and operates to self-hold, and when both the alarm relay SR and the slow release relay SLR are restored, the coil is de-energized. The alarm control relay R operates when the coil is always excited, the coil is de-energized when the alarm relay SR is restored, outputs a level crossing alarm signal, and operates when the alarm stop holding relay CSR operates. Stops alarm signal output.

この踏切制御装置で踏切制御を行う時の動作を図３のフローチャートを参照して説明する。   The operation when the crossing control is performed by the crossing control device will be described with reference to the flowchart of FIG.

直流送電部７は、常時、踏切始動点でレール２に直流電流を送り出し、この送り出された直流電流を踏切３の近傍に設けた受電部１２で受電して車両検知リレーＡＲＴＰを動作させておく。この状態で車両１が踏切始動点に接近し（ステップＳ１）、車軸検知器５で車両１の車軸を検知すると、車軸検知信号を踏切始動制御部４に送る（ステップＳ２）。踏切始動制御部４は最初の車軸検知信号を入力すると、車両１が踏切始動点に接近したと判断して車両接近検知リレーＡＲＴのコイルを非励磁にして復旧させる。車両接近検知リレーＡＲＴが復旧すると直流電源９と直流送電部７の間に接続された車両接近検知リレーＡＲＴの動作接点ＡＲＴが開となり、直流送電部７に供給している直流電力を断にして、直流送電部７からレール２に送っている直流電流を遮断する（ステップＳ３）。レール２に送っている直流電流が遮断されると、受電部１２は車両検知リレーＡＲＴＰのコイルを非励磁にして復旧させる。車両検知リレーＡＲＴＰが復旧すると、警報リレーＳＲのコイルを非励磁にして踏切制御処理を開始する（ステップＳ４）。警報リレーＳＲのコイルが非励磁になると、警報リレーＳＲの動作接点ＳＲが開となり、警報制御リレーＲのコイルを非励磁にして踏切警報信号を出力して踏切制御を行う（ステップＳ５）。一方、車両１が車軸検知器７の位置を通過すると、踏切始動制御部４は車両接近検知リレーＡＲＴのコイルを励磁して直流送電部７からレール２に直流電流を送る。この直流電流を受電した受電部１２は車両検知リレーＡＲＴＰのコイルを励磁させる。   The DC power transmission unit 7 always sends a DC current to the rail 2 at the railroad crossing starting point, and receives the sent DC current by the power receiving unit 12 provided in the vicinity of the railroad crossing 3 to operate the vehicle detection relay ARTP. . In this state, the vehicle 1 approaches the level crossing start point (step S1), and when the axle detector 5 detects the axle of the vehicle 1, an axle detection signal is sent to the level crossing start control unit 4 (step S2). The level crossing start control unit 4 receives the first axle detection signal, determines that the vehicle 1 has approached the level crossing start point, and restores the coil of the vehicle approach detection relay ART by de-excitation. When the vehicle approach detection relay ART is restored, the operation contact ART of the vehicle approach detection relay ART connected between the DC power source 9 and the DC power transmission unit 7 is opened, and the DC power supplied to the DC power transmission unit 7 is cut off. Then, the DC current sent from the DC power transmission unit 7 to the rail 2 is interrupted (step S3). When the direct current sent to the rail 2 is interrupted, the power reception unit 12 restores the coil of the vehicle detection relay ARTP by de-energizing. When the vehicle detection relay ARTP is restored, the crossing control process is started by de-energizing the coil of the alarm relay SR (step S4). When the coil of the alarm relay SR is de-energized, the operating contact SR of the alarm relay SR is opened, and the coil of the alarm control relay R is de-energized and a level crossing alarm signal is output to perform level crossing control (step S5). On the other hand, when the vehicle 1 passes the position of the axle detector 7, the railroad crossing start control unit 4 excites the coil of the vehicle approach detection relay ART and sends a DC current from the DC power transmission unit 7 to the rail 2. The power receiving unit 12 that has received the direct current excites the coil of the vehicle detection relay ARTP.

この状態で車両１が走行し踏切３を通過して、ＡＴＳ地上子１１が車両１に搭載したＡＴＳ車上子１２と電磁結合すると、受信器１０は進出検知リレーＥＸＲのコイルを励磁して動作させる。進出検知リレーＥＸＲが動作すると進出検知リレーＥＸＲの動作接点ＥＸＲが閉となり警報停止保持リレーＣＳＲを動作させ、警報停止保持リレーＣＳＲの動作接点ＣＳＲが閉となり、警報リレーＳＲを動作させる（ステップＳ６）。車両１がＡＴＳ地上子１１を通過してＡＴＳ地上子１１とＡＴＳ車上子１２の電磁結合が解除されると、受信器１０は進出検知リレーＥＸＲのコイルを非励磁にして復旧させる（ステップＳ７）。進出検知リレーＥＸＲが復旧すると進出検知リレーＥＸＲの復旧接点ＥＸＲが閉となり警報制御リレーＲを動作させて踏切警報信号の出力を停止して踏切制御を終了する（ステップＳ８）。   In this state, when the vehicle 1 travels and passes through the railroad crossing 3 and the ATS ground unit 11 is electromagnetically coupled to the ATS vehicle upper unit 12 mounted on the vehicle 1, the receiver 10 operates by exciting the coil of the advance detection relay EXR. Let When the advance detection relay EXR is operated, the operation contact EXR of the advance detection relay EXR is closed and the alarm stop holding relay CSR is operated, and the operation contact CSR of the alarm stop holding relay CSR is closed and the alarm relay SR is operated (step S6). . When the vehicle 1 passes through the ATS ground element 11 and the electromagnetic coupling between the ATS ground element 11 and the ATS vehicle element 12 is released, the receiver 10 is restored by de-energizing the coil of the advance detection relay EXR (step S7). ). When the advance detection relay EXR is restored, the recovery contact EXR of the advance detection relay EXR is closed, the alarm control relay R is operated to stop the output of the level crossing warning signal, and the level crossing control is terminated (step S8).

このように踏切始動点には直流電流を送り出す２芯の電源ケーブルをレール２に接続するとともに踏切始動点の車両進入側に車軸検知器５を設け、踏切３の近傍にはレールに送り出している直流電流を受電する受電部１２とＡＴＳ地上子１１を設けることにより踏切警報区間に車両１が進入したことと踏切警報区間から車両１が進出したことを検知できるから、車軸によるレール短絡が不安定であるデュアルモード・トランスポート・システムにおいても、簡単な構成で踏切制御を確実に行うことができる。   In this way, a two-core power cable for sending a direct current is connected to the rail 2 at the railroad crossing starting point, and the axle detector 5 is provided on the vehicle entrance side of the railroad crossing starting point, and is sent to the rail near the railroad crossing 3. By providing the power receiving unit 12 for receiving DC current and the ATS ground element 11, it is possible to detect that the vehicle 1 has entered the railroad crossing warning section and that the vehicle 1 has advanced from the railroad crossing warning section. Even in the dual mode transport system, the crossing control can be reliably performed with a simple configuration.

前記説明では、車軸検知器５で車両１の車軸を検知したときに踏切始動制御部４で車両接近検知リレーＡＲＴのコイルを非励磁にして、直流送電部７からレール２に送っている直流電流を遮断する場合について説明したが、車軸検知器５で車両１の車軸を検知したときに踏切始動制御部４で直流送電部７を直接制御して直流送電部７からレール２に送っている直流電流を遮断するようにしても良い。   In the above description, when the axle detector 5 detects the axle of the vehicle 1, the level crossing start control unit 4 deenergizes the coil of the vehicle approach detection relay ART, and the DC current sent from the DC power transmission unit 7 to the rail 2. However, when the axle detector 5 detects the axle of the vehicle 1, the DC power transmission unit 7 is directly controlled by the railroad crossing start control unit 4 and sent from the DC power transmission unit 7 to the rail 2. You may make it interrupt | block an electric current.
