Description

本発明は、踏切制御装置に係り、特に列車が踏切道を通過したときに速やかに踏切を開放できるようにするものに関する。 The present invention relates to a railroad crossing control apparatus, and more particularly, to a railroad crossing control device that can quickly open a railroad crossing when a train passes a railroad crossing.

従来、この種の踏切制御装置は、踏切道の所定手前の列車の走行するレールの所定位置に閉電路式の踏切制御子を設けるとともに、その踏切道の近傍で、列車の進出側のレールの所定位置に開電路式の踏切制御子を設けて構成されている。そして、踏切道のうち所定手前に設けられている踏切制御子が踏切道に向けて進行してくる列車を検知すると、踏切道に設置されている踏切しゃ断機や踏切警報機等の踏切機器を駆動開始させ、列車の通過が踏切道近傍に設けられている踏切制御子で検知されたときに踏切機器の駆動を停止させて踏切道を開放するように構成されている（非特許文献１参照）。また、軌道回路又は列車に設けられている車上子及び地上に設けられている地上子間の通信を利用した踏切制御装置も提案されている（特許文献１，２参照）。 Conventionally, this type of railroad crossing control device has been provided with a closed-circuit type railroad crossing controller at a predetermined position of a rail on which a train travels in front of a railroad crossing, and in the vicinity of the railroad crossing, An open circuit type railroad crossing controller is provided at a predetermined position. When the railroad crossing controller provided in the foreground of the railroad crossing detects a train traveling toward the railroad crossing, a railroad crossing device such as a railroad crossing breaker or a railroad crossing alarm installed on the railroad crossing is installed. The driving is started, and when the passage of the train is detected by a railroad crossing controller provided in the vicinity of the railroad crossing, the driving of the railroad crossing device is stopped to open the railroad crossing (see Non-Patent Document 1). ). Further, a railroad crossing control device using communication between a vehicle upper element provided on a track circuit or a train and a ground element provided on the ground has been proposed (see Patent Documents 1 and 2).

The controller 7 outputs a signal for starting driving of the crossing device 1 when the start point crossing controller 4 detects the train T, and the end point crossing controller 5 is similar to the known controller. When the train T is detected, a signal for stopping the driving of the railroad crossing equipment 1 can be output. Further, the controller 7 also takes a level crossing when a signal from the ground unit 6 is input, that is, when a predetermined signal output from the on-board device 2b is input via the on-board unit 3b and the ground unit 6. It is comprised so that the signal which stops the drive of the apparatus 1 can be output.

上記構成からなる踏切制御装置の制御動作を図２のフローチャートを用いて説明する。今、列車Ｔが車上装置２ｂを駆動させながら踏切道イに向けて走行しているとする。列車Ｔが開始点用踏切制御子４に到達して列車検知されると（ステップ１００肯定。以下、ステップを「Ｓ」とする。）、その検知信号が制御器７に入力され、制御器７から踏切機器１に駆動開始信号が出力される。これにより踏切機器１は駆動開始される（Ｓ１０２）。 A control operation of the railroad crossing control apparatus having the above configuration will be described with reference to the flowchart of FIG. Now, it is assumed that the train T is traveling toward the railroad crossing a while driving the on-board device 2b. When the train T reaches the starting point crossing controller 4 and is detected as a train (Yes at Step 100, the step is hereinafter referred to as “S”), the detection signal is input to the controller 7. A driving start signal is output to the railroad crossing device 1. As a result, the crossing device 1 starts to be driven (S102).

列車Ｔの進行がさらに進み、車上装置２ｂの車上子３ｂが地上子６に対向すると、その車上子３ｂから出力されている所定の信号が地上子６により受信され、その受信信号は制御器７に入力される（Ｓ１０４肯定）。制御器７は、地上子６から信号を入力すると、踏切機器１に対して駆動停止の信号を出力し、これにより踏切機器１は駆動停止となり、踏切道イは開放される（Ｓ１０６）。 When the train T further progresses and the vehicle upper element 3b of the on-board device 2b faces the ground element 6, a predetermined signal output from the vehicle upper element 3b is received by the ground element 6, and the received signal is This is input to the controller 7 (Yes at S104). When the controller 7 inputs a signal from the ground unit 6, the controller 7 outputs a drive stop signal to the railroad crossing device 1, whereby the railroad crossing device 1 stops driving and the railroad crossing a is opened (S106).

上述のように、この踏切制御装置においては、地上子６で列車Ｔの通過を点検知により検出できるので、列車Ｔが踏切道イを通過すると同時に開放できる特長がある。なお、地上子６が何らかの理由により列車検知ができないとき、つまり地上子６が空振を起こしたときは、次の終止点用踏切制御子５で列車通過検知が行われたときに踏切機器１の駆動停止が行われる（Ｓ１０４否定、Ｓ１０８肯定、Ｓ１０６）。 As described above, this railroad crossing control device can detect the passage of the train T by the point detection by the ground element 6, and thus has the feature that the train T can be opened simultaneously with passing the railroad crossing a. In addition, when the ground element 6 cannot detect the train for some reason, that is, when the ground element 6 causes the air vibration, the railroad crossing device 1 is detected when the next end crossing controller 5 detects the passage of the train. Is stopped (No in S104, Yes in S108, S106).

図３は、本発明の他の実施の形態に係る踏切制御装置を示すもので、車上装置２ａは先頭車両Ｔ₁に設けられたＡＴＳ地上装置（以下、「１エンド装置」という。）で構成され、車上装置２ｂは後部車両Ｔ₂に設けられたＡＴＳ地上装置（以下、「２エンド装置」という。）で構成されている。また、地上子６は、踏切道イから列車Ｔの編成長（図示の例では２両編成長）だけ進出させた位置に設けられている。そして、この地上子６は、１エンド装置２ａから出力されるＡＴＳ信号を車上子３ａを介して入力できるように構成されている。この他の構成は、上記図１と同様である。 Figure 3 shows the crossing control device according to another embodiment of the present invention, ATS ground device onboard system 2a is provided in the leading vehicle T ₁ (hereinafter, referred to as "first end device".) In configured, onboard device 2b ATS ground device provided in the rear vehicle T ₂ (hereinafter, referred to as. "2 end device") is composed of. Further, the ground element 6 is provided at a position advanced from the railroad crossing a by the train growth of the train T (in the illustrated example, two-car train growth). And this ground element 6 is comprised so that the ATS signal output from the 1 end apparatus 2a can be input via the vehicle upper element 3a. Other configurations are the same as those in FIG.

上記構成からなる踏切制御装置は、レールＲを走行する列車Ｔの編成長が固定されているときに適用される。なお、この踏切制御装置の制御動作は、上記図１及び図２に示される踏切制御動作が車上子３ｂが地上子６と対向した時点で踏切機器１の駆動が停止されるのに対し、車上子３ａが地上子６と対向した時点で踏切機器１の駆動が停止される点を除いて同じなので、これ以上の説明は省略する。 The railroad crossing control device having the above configuration is applied when the knitting growth of the train T traveling on the rail R is fixed. The control operation of the crossing control device is such that the crossing control operation shown in FIGS. 1 and 2 stops the driving of the crossing device 1 when the vehicle upper element 3b faces the ground element 6. Since it is the same except that the driving of the railroad crossing device 1 is stopped when the vehicle upper member 3a faces the ground child 6, further description thereof is omitted.

図４は、本発明のさらに他の実施の形態に係る踏切制御装置を示すもので、レールＲを走行する列車Ｔの編成長が複数種類存在する場合に適用される。図示の例では、列車Ｔの編成長が２両及び３両の２種類の場合が示されている。そして、地上子は編成長に合わせて設置され、地上子６は、上記図１及び図３と同様に列車Ｔの編成が２両用であり、地上子６´は、図示のように車両Ｔ₁，Ｔ₂，Ｔ₃からなる３両編成用で、地上子６よりも１両分だけ踏切道イよりも離れて設けられている。この地上子６´及びこの地上子６´用の受信器６ａ´は、上記地上子６及び受信器６ａとそれぞれ同様に構成されている。 FIG. 4 shows a railroad crossing control apparatus according to still another embodiment of the present invention, and is applied when there are a plurality of types of knitting growth of a train T traveling on a rail R. In the example shown in the figure, there are two cases where the train T has two types of knitting growth, two and three. Then, the ground unit is installed in accordance with the knitting growth, the ground unit 6 is for two trains as in FIGS. 1 and 3, and the ground unit 6 ′ is the vehicle T ₁ as shown. , T ₂ , T ₃ , for a three-car train, and is provided at a distance from the railroad crossing a by one car from the ground element 6. The ground element 6 ′ and the receiver 6a ′ for the ground element 6 ′ are configured in the same manner as the ground element 6 and the receiver 6a, respectively.

図４中、８は電磁式又は光電式等の周知の車軸検知器からなる本発明の車軸数検出手段をなす車軸検知器であり、８ａは、本発明の車軸数検出手段をなす車軸計数器であり、車軸検知器８からの検出信号に基づいて列車Ｔの車軸数（車輪数）を検出できるように構成されている。 In FIG. 4, reference numeral 8 denotes an axle detector that constitutes an axle number detecting means of the present invention comprising a known axle detector such as an electromagnetic type or a photoelectric type, and 8a denotes an axle counter constituting the axle number detecting means of the present invention. And the number of axles (the number of wheels) of the train T can be detected based on the detection signal from the axle detector 8.

上記車軸検知器８は、列車Ｔの先頭（車両Ｔ₁）が地上子６に達する前に車軸の検知が終了する位置に設置されるように決められている。すなわち、車軸検知器８と地上子６との間の距離Ｌ中に、レールＲを走行する最も長い編成の列車Ｔが十分に入るように決められている。この条件が満たされれば、車軸検知器８は、開始点用踏切制御子４よりも踏切道イ側でなくともよい。なお、上記車軸計数器８ａは、制御器７内に組込むことも可能である。 The axle detector 8 is determined to be installed at a position where the detection of the axle is completed before the head of the train T (vehicle T ₁ ) reaches the ground element 6. That is, it is determined that the longest train T traveling on the rail R enters the distance L between the axle detector 8 and the ground unit 6 sufficiently. If this condition is satisfied, the axle detector 8 does not have to be closer to the railroad crossing side than the start point crossing controller 4. The axle counter 8a can be incorporated in the controller 7.

上記構成からなる踏切制御装置の制御動作を図５のフローチャートを用いて説明する。今、列車Ｔが１エンド装置２ａを駆動させながら踏切道イに向けて走行しているとする。列車Ｔが開始点用踏切制御子４に到達して列車検知されると（ステップ２００肯定。）、その検知信号が制御器７に入力され、制御器７から踏切機器１に駆動開始信号が出力される。これにより踏切機器１は駆動開始される（Ｓ２０２）。そして、列車Ｔが車軸検知器８にさしかかると、列車Ｔの車軸数が車軸計数器８ａにより計数され（Ｓ２０４肯定。Ｓ２０６肯定）、この計数された車軸通により制御器７では列車Ｔの編成長が判定されるとともに、使用する地上子が選択される（Ｓ２０８，Ｓ２１０）。図示の例では１２個の車軸数が検出されて３両編成と判定され、地上子６´が選択される。 The control operation of the crossing control apparatus having the above configuration will be described with reference to the flowchart of FIG. Now, it is assumed that the train T is traveling toward the railroad crossing a while driving the one end device 2a. When the train T reaches the starting point crossing controller 4 and a train is detected (Yes at step 200), the detection signal is input to the controller 7, and a drive start signal is output from the controller 7 to the crossing device 1. Is done. As a result, the crossing device 1 starts to be driven (S202). Then, when the train T reaches the axle detector 8, the number of axles of the train T is counted by the axle counter 8a (Yes in S204, Yes in S206). Is determined, and the ground unit to be used is selected (S208, S210). In the example shown in the figure, the number of 12 axles is detected, it is determined that the vehicle is a three-car train, and the ground unit 6 'is selected.

列車Ｔの進行がさらに進み、１エンド装置２ａの車上子３ａが地上子６´に対向すると、その車上子３ａから出力されているＡＴＳ信号が地上子６´により受信され、その受信信号は制御器７に入力される（Ｓ２１２肯定）。制御器７は、地上子６´から信号を入力すると、踏切機器１に対して駆動停止の信号を出力し、これにより踏切機器１は駆動停止となり、踏切道イは開放される（Ｓ２１４）。 When the train T further progresses and the vehicle upper element 3a of the one-end device 2a faces the ground element 6 ', the ATS signal output from the vehicle upper element 3a is received by the ground element 6', and the received signal Is input to the controller 7 (Yes in S212). When the controller 7 inputs a signal from the ground element 6 ', it outputs a drive stop signal to the crossing device 1, whereby the crossing device 1 stops driving and the crossing road a is opened (S214).

上述のように、この踏切制御装置においては、地上子６´で列車Ｔの通過を点検知により検出できるので、列車Ｔが踏切道イを通過すると同時に開放できる特長がある。なお、地上子６´が何らかの理由により列車検知ができないとき、つまり地上子６´が空振を起こしたときは、次の終止点用踏切制御子５で列車検知が行われたときに踏切機器１の駆動停止が行われる（Ｓ２１２否定、Ｓ２１６肯定、Ｓ２１４）。 As described above, the railroad crossing control device can detect the passage of the train T by the point detection by the ground element 6 ', and thus has the feature that the train T can be opened simultaneously with passing the railroad crossing a. In addition, when the ground element 6 'cannot detect the train for some reason, that is, when the ground element 6' causes a vibration, the railroad crossing device is used when the next end point crossing controller 5 detects the train. 1 is stopped (S212 negative, S216 positive, S214).

なお、上述の例では、レールＲを走行する列車Ｔの編成長を２両又は３両としたが、４両以上の編成長の列車が走行する場合であってもよい。この場合、地上子は４両以上の編成長の列車に対応したものも設置される。 In the above-described example, the knitting growth of the train T traveling on the rail R is two or three, but it may be a case where four or more knitting growth trains are traveling. In this case, a ground unit corresponding to a train having four or more trains is also installed.
