Description

本発明は、無線の地上送受信機，車上送受信機を備えた列車進入・進出検知装置および在線列車管理装置に関し、特に踏切制御装置に関するものである。   The present invention relates to a train approaching / advance detection device and a train management device that includes a wireless ground transceiver and an on-vehicle transceiver, and more particularly to a railroad crossing controller.

従来、列車の位置検知は、一般には、地上で軌道回路によって行われている。しかしながら、外的ノイズまたは雨、霧、雪等の天候の影響や、レールの路面の錆が進行して車軸短絡電流が減少することにより、列車の検知特性が不安定となり、列車検知ができない場合があるという問題点があった。また、複線区間のような列車の走行方向が予め決まっている場合と違い、単線区間の場合には上り下りと双方から列車が走行してくることから、列車有無の検知の他に、走行方向の検知のために別の装置が必要となるため、軌道回路の調整が難しく、保守に多大な労力を費やさなければならないという問題点があった。   Conventionally, the position detection of a train is generally performed by a track circuit on the ground. However, when the train detection characteristics become unstable due to the influence of external noise or weather such as rain, fog, snow, etc., or the rust on the rail road surface and the axle short circuit current decreases, the train cannot be detected. There was a problem that there was. In addition, in the case of a single track section, the train travels from both the up and down directions, in addition to the detection of the presence of the train. Since a separate device is required to detect this, it is difficult to adjust the track circuit, and a great amount of labor must be spent for maintenance.

そこで、踏切に接近する列車と踏切を通過する列車を検知する列車検知装置と、踏切を制御する踏切制御装置とを備え、踏切に接近する列車を検知する列車検知装置および踏切を通過する列車を検知する列車検知装置は、搬送波を変調した送信波を生成する変調手段と、列車検知装置から検知距離までの検知範囲に送信波を発射し、電波を受信する送受信手段と、電波を復調し、電波が送信波に対する反射波であることを判定する復調手段と、電波が送信波に対する反射波であると判定され、且つ、反射波のレベルが所定値以上の場合、検知範囲内に列車あるいは障害物を検知したと判定する判定手段とを含み、踏切制御装置は、各列車検知装置からの検知結果に応じて踏切を制御する踏切制御システムが開示されている（特許文献１）。
上記は、電波の反射波によって列車の存在有無、進行方向を検知しているが、車両情報を認識することはできい。また、しきい値を用い複雑な判定処理を行っている。 Therefore, a train detection device that detects a train approaching the level crossing and a train that passes the level crossing, and a crossing control device that controls the level crossing, a train detection device that detects a train approaching the level crossing, and a train that passes the level crossing. The train detection device to detect is a modulation means for generating a transmission wave modulated with a carrier wave, a transmission / reception means for emitting a transmission wave to a detection range from the train detection device to a detection distance, and receiving a radio wave, and demodulating the radio wave, Demodulation means for determining that the radio wave is a reflected wave with respect to the transmitted wave, and when the radio wave is determined to be a reflected wave with respect to the transmitted wave and the level of the reflected wave is equal to or higher than a predetermined value, the train or obstacle is within the detection range. A crossing control system that includes a determination unit that determines that an object has been detected and that controls a crossing according to a detection result from each train detection device is disclosed (Patent Document 1).
In the above, the presence / absence of a train and the traveling direction are detected by reflected waves of radio waves, but vehicle information cannot be recognized. In addition, complicated determination processing is performed using threshold values.

また、閉そく区間の境界にレールを挟んで送信部と受信部が配置された狭指向の無線通信領域を持つ地上送受信機と、列車上に配置され、当該列車の編成識別情報を前記地上送受信機へ送信する、狭指向の無線通信領域を持つ車上送受信機と、前記地上送受信機における前記送信部と前記受信部間の通信の遮断，回復と前記地上送受信機における前記編成識別情報の受信にもとづいて列車の進入・進出の検知処理手段を行う検知処理手段とを備えた列車進入・進出システムにおいて、

上記の列車進入の検知処理は、前記通信の遮断があったとき列車編成検知テーブルに不確定編成を登録し、続いて前記編成識別情報の受信で、その編成を登録した後前記不確定編成を削除し、続いて前記通信の回復で、前記編成を削除する複雑な処理を行っている。 A ground transmitter / receiver having a narrowly-oriented wireless communication area in which a transmitter and a receiver are arranged with a rail sandwiched between borders of a block section; and a train identification information of the train arranged on the train. On-board transmitter / receiver having a narrowly-oriented wireless communication area to be transmitted to, and interruption / recovery of communication between the transmitter and the receiver in the ground transmitter / receiver and reception of the organization identification information in the ground transmitter / receiver In the train approach / advance system equipped with the detection processing means for performing the detection processing means of the train entry / exit based on,
The detection processing means performs a train approach detection process when the train identification information is received following the interruption of the communication, and when the communication is recovered following the reception of the train identification information. In addition, it is a means to detect the train advance,
The train approach detection process registers an indeterminate composition in the train composition detection table when the communication is interrupted, and then registers the composition in the train composition detection table when the composition identification information is received. After that, there is disclosed a train approach / advance detection system that is a process of deleting the undefined train and then deleting the train of the train train detection table when the communication is restored (Patent Document 2). .
The train entry detection process registers the undefined composition in the train composition detection table when the communication is interrupted, and then receives the composition identification information to register the composition and then the undefined composition. Then, a complicated process of deleting the organization is performed in the communication recovery.

本発明の列車検知装置は、地上質問器が、接近列車の車上応答器に対向して設けられているので、該地上質問器と該車上応答器の通信開始と同時、直ちに列車の走行方向と車両情報を認識することができ、続いて地上質問器と車上応答器の通信遮断で列車進入、通信回復で列車進出を判定できるので、走行方向の検知のために別の装置を必要とせず、軌道回路の保守が不要になり、軌道回路に較べて踏切制御装置の誤動作を防止でき、踏切遮断時間の短縮化が図れ、
質問器と応答器は、デジタル伝送方式をとるので、耐ノイズ性や信頼性が高く、
応答器の電力は、質問器の搬送波電力により給電されるので、省電力化が図れ、
地上応答器と地上質問器の配置は、通信が列車により斜め方向で遮断される位置に設置されているので、列車連結部空間や車両形状（貨車、平台、石灰運搬車、車掌車、ＳＬ、客車、電気機関車等）などによる通信回復を防止することができ、確実に列車の進出を検知することができ、従来の軌道回路より列車検知が短距離で済むため、列車通過後直ぐに踏切遮断機を開放でき、さらには、車上応答器を列車の前面または／および後面に取り付けているので、列車側面に取り付けるよりも時間的に永く地上質問器と電波の送受信を行うことができ高速列車にも対応でき、
地上応答器と通信する地上質問器とは別に、追加の車上応答器と１対１で通信する地上質問器とすることも可能で、地上応答器の設置を容易化でき、また、接近してくる列車を確実に検知することができ、

車上応答器を列車の前面両側と後部両側に設けた場合、列車方向が前後反転してもよく、地上質問器を列車の車体がそれより外方に出っ張らない車両限界線外側左右どちら側に設けてもよいので、種々現場状況に合わせることができ、
制御装置へ当該制御装置外の装置へ出力する出力手段を備えているので、踏切装置のみならず各種装置との連動を図ることができ応用範囲が広く、
列車検知地点を列車通過後も車両情報を取れるようにしたので、地上応答器と地上質問器の通信回復検知と合わせて列車進出の検知を行い、踏切内での折り返し運行にも対応（構内作業、入れ替え作業などにより踏切領域内で、途中から進行してきた逆方向へ戻る運行時、地上質問器は、戻ってくる列車の車両情報を明確に判定できるので一旦遮断した踏切を開放することができるなど）でき、列車前面の車上応答器が故障していても列車後面の車上応答器で、列車が通過した後列車が遠ざかる方向へ向けて設けた地上質問器と電波の送受信を行うことで、確実に車両情報を認識することができ、
地上質問器１台に対し地上応答器２台を備えたので、設備費用が嵩まずにフェイルセーフを配慮できる
等々、低コストで確実に動作する列車の進入・進出を検知する列車検知装置および在線列車管理装置を提供することができる。 In the train detection device of the present invention, since the ground interrogator is provided opposite to the onboard responder of the approaching train, the train immediately travels simultaneously with the start of communication between the ground interrogator and the onboard responder. It is possible to recognize the direction and vehicle information, and then determine whether the train is approaching by disconnecting communication between the ground interrogator and on-board responder, and whether the train has advanced by recovering communication, so another device is required to detect the direction of travel. Therefore, maintenance of the track circuit becomes unnecessary, and it is possible to prevent a malfunction of the railroad crossing control device compared to the track circuit, and to shorten the railroad crossing interruption time,
The interrogator and responder use a digital transmission system, so they have high noise resistance and reliability.
The power of the transponder is supplied by the interrogator's carrier power.
Since the ground responder and the ground interrogator are installed at a position where the communication is cut off in an oblique direction by the train, the train connection space and the vehicle shape (freight car, flatbed, lime carrier, conductor, SL, Passengers, electric locomotives, etc.) can be prevented from recovering, train advancement can be detected reliably, and train detection can be done in a shorter distance than conventional track circuits. The aircraft can be opened, and the onboard responder is attached to the front or / and rear of the train. Can also support
Apart from the ground interrogator that communicates with the ground responder, it can also be a ground interrogator that communicates with an additional on-board responder one-on-one, facilitating the installation of the ground responder and approaching it. It can detect the incoming train reliably,
Because the ground interrogator is installed diagonally upward or diagonally downward, even if the vehicle moves, it can enter the antenna's directivity angle and transmit and receive radio waves reliably.
When the onboard responders are installed on both the front and rear sides of the train, the train direction may be reversed, and the ground interrogator is placed on either the left or right side of the vehicle limit line where the train body does not protrude outward. Since it may be provided, it can be adapted to various site conditions,
Since it has output means to output to the control device to the device outside the control device, it can be linked with various devices as well as the crossing device, and the application range is wide,
Since the vehicle information can be obtained even after passing the train at the train detection point, it detects the advance of the train together with the communication recovery detection of the ground responder and the ground interrogator, and also supports the return operation within the railroad crossing (premise work In the crossing area due to replacement work, the ground interrogator can clearly determine the vehicle information of the returning train at the time of operation to return in the reverse direction that progressed from the middle, so that it is possible to release the crossing once interrupted Even if the on-board responder on the front of the train fails, the on-board responder on the rear of the train can transmit and receive radio waves to and from the ground interrogator that is installed in the direction away from the train after the train has passed. Can reliably recognize vehicle information,
Since there are two ground responders for one ground interrogator, the train cost can be considered without failing to increase the equipment cost, etc. A train management device can be provided.
