Description

本発明は、ランプを点灯または消灯させて列車のドアの開閉状態を報知する車側灯に関するとともに、その車側灯を用いた列車ドア開閉検知装置に関する。   The present invention relates to a vehicle side lamp that informs the open / closed state of a train door by turning on or off the lamp, and also relates to a train door open / close detection device using the vehicle side lamp.

従来、列車（電車を含む）の両車を構成する筐体の側面上部には、その列車のドアが開かれたときに点灯し、その列車のドアが閉じられたときに消灯する車側灯が設けられている。したがって、列車の乗務員又はホームの駅員等の係員は、車側灯の点滅状態により列車のドアの開閉状態を確認することができ、列車の安全運転に資することができる。また、ホームドア装置においては、車側灯が点灯したことを画像処理して検知し、又は受光センサにより検知してホームドアの開閉制御を行うことが提案されている（特許文献１参照）。   Conventionally, the car side lamp that lights up when the door of the train is opened, and goes off when the door of the train is closed, on the upper side of the chassis that constitutes both cars of the train (including the train) Is provided. Therefore, an attendant such as a train crew member or a train station staff member can confirm the open / closed state of the train door based on the blinking state of the vehicle side light, which can contribute to safe driving of the train. Moreover, in the platform door apparatus, it has been proposed to perform image processing to detect that the vehicle side lamp has been lit or to detect opening / closing of the platform door by a light receiving sensor (see Patent Document 1).

特開２００４−２０３３２０号公報Japanese Patent Laid-Open No. 2004-203320

上述のように、車側灯は、列車のドアの開閉状態を確実に報知できる特長を有しているので、この特長を他の制御装置に応用したいという要望があった。本発明の実施の形態の項で用いる図８を用いてさらに説明すると、列車Ｔの停止する甲駅の進行方向近傍に踏切Ｘがある場合で、その甲駅のホームＨの所定位置に列車Ｔが位置したときからその踏切Ｘに設置されている警報機Ｙ1及び踏切しゃ断機Ｙ2が駆動を開始するように制御されている場合は、列車Ｔが甲駅に停車している間も踏切Ｘが閉止されるので踏切Ｘにおける待ち時間が長くなり、列車Ｔの出発に合わせた踏切機器制御が望まれていた。 As described above, since the vehicle side lamp has a feature that can reliably notify the open / closed state of the train door, there is a demand for applying this feature to other control devices. Further explanation will be given using FIG. 8 used in the embodiment of the present invention. When there is a railroad crossing X in the vicinity of the traveling direction of the former station where the train T stops, the train T is located at a predetermined position on the platform H of the former station. When the alarm Y 1 and the level crossing breaker Y 2 installed at the level crossing X are controlled to start driving from when the train is located, the level crossing is also performed while the train T is stopped at Kou Station. Since X is closed, the waiting time at the railroad crossing X becomes long, and it is desired to control the railroad crossing equipment in accordance with the departure of the train T.

また、車側灯の点滅状態を受光センサで検知して、その検知信号を利用する装置において、受光センサには駅のホームに設けられている照明器具や列車の照明器具から照射される光線等も入力されるので、車側灯以外の光線の影響を受けない車側灯の出現も待たれていた。   In addition, in a device that detects the blinking state of the vehicle side light with a light receiving sensor and uses the detection signal, the light receiving sensor includes a lighting device provided at a station platform, a light beam emitted from a train lighting device, etc. Therefore, the advent of car side lights that are not affected by light rays other than car side lights was also awaited.

以下、本発明を実施するための最良の形態を図面に基づいて説明する。図１（ａ）は、本発明に係る列車ドア開閉検知装置を適用した列車の側面図、同図（ｂ）は、その平面図である。レールＲを走行する列車Ｔは、複数（図示の例では２両）の車両Ｔ1，Ｔ2の編成からなり、ここでは、列車Ｔは、甲駅のホームＨの所定の停車位置に停車している状態が示されている。また、この列車Ｔは、ここでは矢印で示されるように左側から右側へ進行するように決められている。なお、列車Ｔの車両編成は１両でもよく、又は３両以上であってもよいが、ここでは説明を簡単にするために、２両編成としている。 Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1A is a side view of a train to which the train door open / close detection device according to the present invention is applied, and FIG. 1B is a plan view thereof. The train T traveling on the rail R is composed of a plurality (two in the illustrated example) of vehicles T 1 and T 2. Here, the train T stops at a predetermined stop position on the platform H of the former station. The state is shown. In addition, the train T is determined so as to travel from the left side to the right side as indicated by an arrow. In addition, although the vehicle organization of the train T may be one or three or more, for the sake of simplicity of explanation, a two-car train is used here.

図中１ａ，１ｂは車側灯であって、各車両Ｔ1，Ｔ2のドアＤが設けられている側面の中程の上部にそれぞれ設けられている。また、図中１０ａ，１０ｂは受光器であって、ホームＨの図示しないフレームに固定して設けられている。すなわち、これら受光器１０ａ，１０ｂは、地上側であるホームＨ側にそれぞれ設けられ、列車ＴがホームＨの所定の停車位置（図２（ｂ）の一点鎖線参照）に停車したときの各車側灯１ａ，１ｂとそれぞれ対向する位置よりも列車Ｔの走行方向（図示の例では、列車Ｔの進行方向）に沿って所定の間隔を保ってそれぞれ設けられ、かつ、これら車側灯１ａ，１ｂから照射される光線をそれぞれ受光できる位置に設けられている。もちろん、これら受光器１０ａ，１０ｂの設置高さは、ホームＨ上の乗客の通行に支障とならないように決められている。 In the figure, reference numerals 1a and 1b denote vehicle side lights, which are respectively provided at the middle upper portions of the side surfaces where the doors D of the vehicles T 1 and T 2 are provided. In the figure, reference numerals 10a and 10b denote light receivers which are fixed to a frame (not shown) of the home H. That is, these light receivers 10a and 10b are provided on the platform H side which is the ground side, and each vehicle when the train T stops at a predetermined stop position of the platform H (refer to a one-dot chain line in FIG. 2B). The vehicle side lights 1a, 1b are provided at predetermined intervals along the traveling direction of the train T (in the illustrated example, the traveling direction of the train T) rather than the positions facing the side lights 1a, 1b, respectively. It is provided at a position where each of the light beams irradiated from 1b can be received. Of course, the installation height of these light receivers 10a and 10b is determined so as not to hinder the passage of passengers on the platform H.

上記車側灯１ａ，１ｂは、同一構成なので、車側灯１ａを例に図２（ａ），（ｂ）を用いて説明する。図２（ａ）は車側灯の斜視図、同図（ｂ）は、同図（ａ）の矢視Ａ−Ａより見た縦断面図である。この車側灯１ａは、周知の車側灯と同様に、直方体の筐体２を有していて、その筐体２の一つの面が車両Ｔ1の側面に接合する形で着脱自在に取り付けられている。そして、その筐体２の車両Ｔ1の車側面と並行する左右両側の面（車両Ｔ1の進行する方向の面及びその方向と反対側の面）は、ダイヤモンドカットされた透光面３，３にそれぞれ形成されている。 Since the vehicle side lamps 1a and 1b have the same configuration, the vehicle side lamp 1a will be described as an example with reference to FIGS. 2 (a) and 2 (b). FIG. 2A is a perspective view of the vehicle side lamp, and FIG. 2B is a vertical cross-sectional view as seen from an arrow AA in FIG.

The left and right surfaces (the surface in the direction in which the vehicle T 1 travels and the surface opposite to that direction) parallel to the vehicle side surface of the vehicle T 1 of the housing 2 are diamond-cut translucent surfaces 3. 3 respectively.

図２（ｂ）中、４は筐体２内に設けられるランプであって、このランプ４は、筐体２の取付けられる車両Ｔ1の側面壁に設けられているソケット５に螺合により取付けられている。このランプ４は、図３に示されるように、本発明の変調回路を含んで構成される駆動回路６とランプ４の発光体をなすＬＥＤ（発光ダイオード）６とが組込まれている。 In FIG. 2B, reference numeral 4 denotes a lamp provided in the housing 2, and this lamp 4 is attached to a socket 5 provided on a side wall of the vehicle T 1 to which the housing 2 is attached by screwing. It has been. As shown in FIG. 3, the lamp 4 includes a drive circuit 6 including the modulation circuit of the present invention and an LED (light emitting diode) 6 that forms a light emitter of the lamp 4.

図４には、ランプ４及び受光器１０ａの電気的構成を示すブロック図が示されている。なお、受光器１０ｂも同一構成であるので、その受光器１０ｂの説明は省略する。このランプ４には、駆動回路７として光出力を所定の周波数に変調させる発振回路７ａと、その発振回路７ａの出力を増幅処理する増幅回路７ｂとを含み、増幅回路７ｂの出力でＬＥＤ６が点灯されるように構成されている。したがってＬＥＤ６は、所定の点灯周期で点灯することができる。なお、点灯周期は、ホームＨで用いられている照明器具の点灯周期や列車Ｔで用いられる電灯の周期と異なるように決められており、例えば、１０２５Ｈｚとされる。   FIG. 4 is a block diagram showing the electrical configuration of the lamp 4 and the light receiver 10a. Since the light receiver 10b has the same configuration, the description of the light receiver 10b is omitted. The lamp 4 includes an oscillation circuit 7a that modulates the optical output to a predetermined frequency as a drive circuit 7, and an amplification circuit 7b that amplifies the output of the oscillation circuit 7a. The LED 6 is lit by the output of the amplification circuit 7b. It is configured to be. Therefore, the LED 6 can be lit at a predetermined lighting cycle. The lighting cycle is determined so as to be different from the lighting cycle of the luminaire used in the home H and the cycle of the lamp used in the train T, and is set to, for example, 1025 Hz.

受光器１０ａは、ＬＥＤ６から照射される光線のみを選択的に透過させるとともに、半導体からなる受光素子１１の受光面を保護する光学フィルタ１２と、受光素子１１の出力信号を増幅処理する増幅回路１３と、増幅回路１３の出力のうちＬＥＤ６側から送出された信号のみを通過させるバンドパスフィルタからなるフィルタ１４と、フィルタ１４からの出力信号を所定のしきい値で処理してＯＮ，ＯＦＦ（１，０）の信号を図示しない地上装置（後述する図８の２０参照）に出力する出力回路１５とから構成されている。すなわち、この受光器１０ａは、ランプ４側からの信号を復調処理して、ランプ４以外の外乱光に伴なう信号を除去できるように構成されている。   The light receiver 10 a selectively transmits only the light emitted from the LED 6, protects the light receiving surface of the light receiving element 11 made of a semiconductor, and an amplification circuit 13 that amplifies the output signal of the light receiving element 11. And a filter 14 composed of a band-pass filter that passes only the signal transmitted from the LED 6 side of the output of the amplifier circuit 13, and the output signal from the filter 14 is processed with a predetermined threshold value to turn on and off (1 , 0) is output to a ground device (not shown) (see 20 in FIG. 8 described later). That is, the light receiver 10 a is configured to demodulate a signal from the lamp 4 side and remove a signal accompanying disturbance light other than the lamp 4.

次に、上記構成からなる車側灯１ａ，１ｂを備えた列車ドア開閉検知装置の動作について図５（ａ），（ｂ）のフローチャートを用いて説明する。先ず、列車Ｔ側（車上側）から説明すると、今、列車Ｔが甲駅に接近し、ホームＨの所定位置（図１（ｂ）の一点鎖線位置を参照）に停車すると（ステップ１００肯定。以下、ステップを「Ｓ」とする。）、列車Ｔは、乗務員によってドアＤの開扱いが行われる（Ｓ１０２肯定）。   Next, operation | movement of the train door opening / closing detection apparatus provided with the vehicle side lights 1a and 1b which consist of the said structure is demonstrated using the flowchart of Fig.5 (a), (b). First, the train T side (the vehicle upper side) will be described. When the train T approaches the former station and stops at a predetermined position of the platform H (see the one-dot chain line position in FIG. 1B) (Yes in step 100). Hereinafter, the step is referred to as “S”.) In the train T, the opening of the door D is performed by the crew (Yes in S102).

各車両Ｔ1，Ｔ2の各ドアＤ，Ｄ…には、ドアの開閉状態を検出する図示しないセンサが設けられているので、そのセンサの検出によりランプ４が点灯し、２つの車側灯１ａ，１ｂが点灯状態に保たれる（Ｓ１０４）。この点灯状態は、列車Ｔの出発が許可されて乗務員によってドアＤの閉扱いが行われ、ドアＤの閉状態がセンナによって検出されるまで継続される（Ｓ１０６肯定、Ｓ１０８肯定、Ｓ１１０）。 Each door D, D ... of each vehicle T 1 , T 2 is provided with a sensor (not shown) for detecting the open / closed state of the door. 1a and 1b are kept in a lighting state (S104). This lighting state is continued until the departure of the train T is permitted, the crew member handles the door D, and the closed state of the door D is detected by the senna (S106 affirmation, S108 affirmation, S110).

地上側においては、車側灯１ａ，１ｂが点灯すると、それら車側灯１ａ，１ｂ（ランプ４）から照射された光線が受光器１０ａ，１０ｂに受入れられて、車側灯１ａ，１ｂが点灯したこと、すなわちドアＤが開けられたことを示す信号が、出力回路１５から地上装置に出力される（Ｓ２００肯定、Ｓ２０２）。この信号は、受光器１０ａ，１０ｂが列車Ｔの走行方向（進行方向）に設けられているので、列車Ｔが所定の停車位置から多少ずれた位置に停車しても確実に出力される特長がある。そして、この出力される信号は、図示しない地上装置に入力されて、例えば、ホームＨの乗客案内に利用される。その案内例としては、ドアＤの前で立ち塞がらないこと、降車客が降車終了後に乗車するよう等の放送案内のスタート信号に用いられる。また、このドア開の検出信号は、後述するように踏切制御装置に入力されて踏切しゃ断機等の踏切機器の駆動信号として用いることができる（Ｓ２０２の鎖線矢印参照）。   On the ground side, when the vehicle side lights 1a and 1b are turned on, the light beams emitted from the vehicle side lights 1a and 1b (lamp 4) are received by the light receivers 10a and 10b, and the vehicle side lights 1a and 1b are turned on. That is, a signal indicating that the door D has been opened is output from the output circuit 15 to the ground device (Yes in S200, S202). Since the light receivers 10a and 10b are provided in the traveling direction (traveling direction) of the train T, this signal has a feature that it is reliably output even if the train T stops at a position slightly deviated from a predetermined stop position. is there. The output signal is input to a ground device (not shown) and is used for, for example, passenger guidance for the home H. As an example of the guidance, it is used as a start signal for broadcast guidance such as not stopping in front of the door D, and getting off the passenger after getting off. Further, the door open detection signal can be input to a level crossing control device and used as a drive signal for a level crossing device such as a level crossing breaker as will be described later (see the chain line arrow in S202).

列車Ｔの出発が許可されて乗務員によりドア閉扱いが行われると、ドアＤは閉じられて、車側灯１ａ，１ｂが消灯される。しかし、各ドアＤの機械的なバラツキにより一斉に消灯することが稀であり、いずれか一方が先に消灯することとなる（Ｓ２０４肯定）。地上装置は、例えば受光器１０ａからの出力信号がＯＦＦになったときは、車上側でドア閉扱いが開始されたと判定し、この判定信号に基づいて所定の処理を行うことができる（Ｓ２０６）。例えば、その判定信号に基づいて、ドアが閉っているので、列車から離れるようにとの案内放送をスタートさせたり、あるいは後述する踏切制御装置を駆動させることができる（Ｓ２０６の鎖線矢印参照）。地上装置は、受光器１０ａ，１０ｂの出力が全てＯＦＦとなったことをもって、列車ＴのドアＤが全て閉じられたと判定することができる（Ｓ２０８肯定、Ｓ２１０）。   When the departure of the train T is permitted and the door crew handles the door, the door D is closed and the vehicle side lights 1a and 1b are turned off. However, it is rare that the doors D are turned off all at once due to mechanical variations of the doors D, and either one is turned off first (Yes in S204). For example, when the output signal from the light receiver 10a is turned off, the ground device determines that door closing has been started on the upper side of the vehicle, and can perform predetermined processing based on this determination signal (S206). . For example, since the door is closed based on the determination signal, it is possible to start a guidance broadcast to leave the train or to drive a railroad crossing control device to be described later (see the chain line arrow in S206). . The ground device can determine that all the doors D of the train T are closed when all the outputs of the light receivers 10a and 10b are turned off (Yes in S208, S210).

図６は、車側灯１ａ，１ｂの他の例を示したもので、筐体２の正面側（車両Ｔ1，Ｔ2の側面と平行する面側）もダイヤモンドカットされた透光面３に形成されている。そして、この筐体２の正面側に対向するホームＨ側には、受光器１０ａ，１０ｂと同種の受光器１０ｃが車側灯１ａ又は車側灯１ｂのいずれか一方に設けられている。このように、受光器１０ｃがさらに設けられると、図示しない地上装置は、受光器１０ａと受光器１０ｃ（受光器１０ｃが車側灯１ｂ側に設けられているときに、受光器１０ｂと受光器１０ｃ）の両方で車側灯１ａの光線を受光できたときは、列車Ｔは所定の停車位置に停車したと判定することができる。なお、車側灯１ａ，１ｂの筐体２全体が透光面で形成されている場合、受光器１０ｃは、車側灯１ａ，１ｂの正面側の光線のみを入力できるフードが設けられる。 FIG. 6 shows another example of the vehicle side lights 1a and 1b, and the front surface side of the housing 2 (the surface side parallel to the side surfaces of the vehicles T 1 and T 2 ) is also diamond cut. Is formed. A light receiver 10c of the same type as the light receivers 10a and 10b is provided on either the vehicle side lamp 1a or the vehicle side lamp 1b on the home H side facing the front side of the housing 2. Thus, when the light receiver 10c is further provided, the ground device (not shown) can receive the light receiver 10a and the light receiver 10c (when the light receiver 10c is provided on the vehicle side light 1b side, the light receiver 10b and the light receiver). 10c), it can be determined that the train T has stopped at a predetermined stop position when the light from the vehicle side lamp 1a can be received. In addition, when the whole housing | casing 2 of the vehicle side lights 1a and 1b is formed in the translucent surface, the light receiver 10c is provided with the hood which can input only the light ray of the front side of the vehicle side lights 1a and 1b.

図７は、本発明の他の実施の形態を示したもので、受光器１０により２つの車側灯１ａ，１ｂの光線を受光できるようにしている。この場合、車側灯１ａ，１ｂで用いられる点灯周期は互いに異なるように設定されるとともに、受光器１０には、それら２つの点灯周期を分別して受信できるように構成されている。すなわち、図４に示されるフィルタ回路１４及び出力回路１５は、車側灯１ａ，１ｂに対応させて並設される。なお、１個の受光器で３両以上の列車に対向することができるが、列車の編成が６両のような場合は、２車両毎に１個の受光器とすることができる。本発明では、このような場合も「受光器は単一である」という範囲に含めている。また、受光器１０の設置場所は、車両Ｔ1の前方のホームＨではなく、車両Ｔ1，Ｔ2の接続部に対応するホームＨに設けるようにしてもよい。 FIG. 7 shows another embodiment of the present invention, in which the light of the two vehicle side lights 1a and 1b can be received by the light receiver 10. FIG. In this case, the lighting cycles used in the vehicle side lights 1a and 1b are set to be different from each other, and the light receiver 10 is configured to receive the two lighting cycles separately. That is, the filter circuit 14 and the output circuit 15 shown in FIG. 4 are juxtaposed in correspondence with the vehicle side lights 1a and 1b. In addition, although it can oppose 3 or more trains with one light receiver, when the train organization is six, it can be set as one light receiver for every two vehicles. In the present invention, such a case is also included in the range of “a single light receiver”. Also, the location of the light receiver 10, rather than in front of the home H of the vehicle T 1, may be provided to the home H corresponding to the connecting portion of the vehicle T 1, T 2.

図８は、本発明に係る列車ドア開閉装置を踏切機器制御に応用した例を示している。この図８に示される甲駅と踏切Ｘとの関係についは、発明が解決しようとする課題の項で説明してあるので、その説明は省略する。   FIG. 8 shows an example in which the train door opening and closing device according to the present invention is applied to railroad crossing equipment control. Since the relationship between the former station and the railroad crossing X shown in FIG. 8 has been described in the section of the problem to be solved by the invention, the description thereof will be omitted.

図８中、２０は地上装置であり、受光器１０ａ，１０ｂの出力信号（出力回路１５の出力信号）を入力し、警報機Ｙ1及びしゃ断機Ｙ2からなる踏切機器を駆動制御する踏切制御装置３０に駆動信号を出力できるように構成されていて、図示しないＣＰＵ（中央処理装置）を中心に構成されている。すなわち、この地上装置２０は、受光器１０ａ又は受光器１０ｂのいずれか一方からの出力信号がＯＦＦになったことをもって列車Ｔが甲駅から出発しようとしていると判定し、その判定に基づく駆動信号を踏切制御装置３０に出力できるように構成されている。 In FIG. 8, reference numeral 20 denotes a ground device, which receives the output signals of the light receivers 10 a and 10 b (output signals of the output circuit 15), and controls the level crossing including the alarm device Y 1 and the cutoff device Y 2. A drive signal can be output to the device 30 and a CPU (central processing unit) (not shown) is mainly configured. That is, the ground device 20 determines that the train T is about to leave from the station A when the output signal from either the light receiver 10a or the light receiver 10b is turned OFF, and a drive signal based on the determination. Is output to the railroad crossing control device 30.

踏切制御装置３０では、地上装置２０から駆動信号を受信すると、警報機Ｙ1を鳴動させるとともに、しゃ断機Ｙ2のしゃ断かんを降下させて踏切Ｘを遮断させる。踏切Ｘは、列車Ｔの実際の出発に合わせて遮断されるので、踏切の待ち時間の適正化を図ることができる。 In crossing the controller 30, when receiving a drive signal from the ground device 20, it causes sounding the alarm Y 1, thereby interrupting the crossing X is lowered to cut off cans of cutoff machine Y 2. Since the railroad crossing X is cut off in accordance with the actual departure of the train T, it is possible to optimize the railroad crossing waiting time.

上述の例では、ドアＤの閉の検出信号に基づいて踏切機器を制御したが、ドアＤの開の検出信号に基づいて踏切機器を制御する場合は、ドアＤが開かれてから所定時間経過後に、すなわち、列車Ｔの停止位置と踏切Ｘとの位置関係から踏切Ｘにおける待ち時間が最適となるように決められた所定の時間経過後に踏切機器の駆動を開始させるようにしてもよい。   In the above example, the railroad crossing device is controlled based on the door D closing detection signal. However, when the railroad crossing device is controlled based on the door D opening detection signal, a predetermined time has elapsed since the door D was opened. Later, that is, driving of the railroad crossing device may be started after a predetermined time has elapsed so that the waiting time at the railroad crossing X is optimized based on the positional relationship between the stop position of the train T and the railroad crossing X.

なお、本発明に係る列車ドア開閉検知装置を踏切機器制御に適用する場合は、受光器１０ｃのみの出力信号を用いることも可能である。すなわち、車側灯１ａ又は車側灯１ｂに対向して設けられた受光器１０ｃ（この場合の受光器１０ｃは、列車Ｔが所定の停車位置に停車したことを検知するものでなく、単にドアＤが閉じられたことを検知するものでもよい。）がドアＤの開又は閉を検知したときに、その検知信号に基づいて警報機Ｙ1等の踏切機器に対して所定の駆動信号を出力して踏切の待ち時間の適正化を図ることができる。 In addition, when applying the train door open / close detection device according to the present invention to railroad crossing equipment control, it is also possible to use the output signal of only the light receiver 10c. That is, a light receiver 10c provided opposite to the vehicle side light 1a or the vehicle side light 1b (in this case, the light receiver 10c does not detect that the train T has stopped at a predetermined stop position, but is simply a door). D may be detected to be closed.) When the door D is detected to be opened or closed, a predetermined drive signal is output to the crossing device such as the alarm device Y 1 based on the detection signal. Thus, it is possible to optimize the waiting time for a crossing.
