Description

本発明は、分岐器を備えた鉄道線路における保守用車のための安全運転装置に関するものである。 The present invention relates to a safe driving device for a maintenance vehicle on a railway track provided with a branching device.

従来、分岐器を備えた鉄道線路において、保守点検のために保守用車を走行させ、特に夜間において転線させる場合に、該分岐器のトングレール部による開通方向が判別し難く、そのため該分岐器手前で保守用車を一旦停車し、監督者が保守用車から降車して開通方向を確認してから保守用車の走行を行っていたが、この様な確認方法は、分岐器の開通方向を確認して保守用車走行させるまでに時間を要し、作業効率が悪いばかりでなく、開通方向の誤認等により異線方向に走行したり、或いは割り出し事故を誘発する等の恐れがあった。
この問題を解決するために、該分岐器のトングレール部の転換に連動して回転する表示板で開通方向を表示する方法が、特許文献１にて提案されているが、この回転表示板による方法は、機構が複雑であり、且つ夜間は視認し難く、満足のいくものではなかった。
そこで、本件発明者らにより、太陽電池と蓄電池による独立電源を備え、トングレール部の動きを切り換えスイッチにより検出し、これによって分岐器の開通方向を、滑走路の誘導灯のように枕木上に数個づつ設置した両面発光型表示器（発光ダイオード内臓）を点滅発光させ、これにより分岐器の開通方向を明示する保守用車進路確認装置が特許文献２により提案済である。
この装置は、保守用車に送信機を搭載し、この保守用車が夜間、電波を送信しつつ分岐器に接近すると、分岐器脇に設置した受信機がその電波を受信した場合にのみ、枕木上に設置した開通方向の発光体を点滅発光させ、保守用車の運転者に分岐器の開通方向を知らしめるものであり、この装置の使用により、分岐器の開通方向は、保守用車から比較的遠方より容易に識別でき、保守用車の運行がより効率的に行えるようになるものである。
更に、運転者による見落としや、誤認による割り出し事故防止のため、特許文献３〜５において、電波を使用した自動停止機能を有する割出防止装置が提案されている。
しかしながら、上記した割出防止装置は、情報の伝達距離が短く、保守用車に搭載した車上子が地上の枕木上に設置した地上子の直上を通過する時にのみしか分岐器の開通情報を伝達できないため、分岐器の進行方向が非開通で停止した場合、保守用車の停止位置は、地上子の位置を通過してしまい、分岐器が転換されて、進行方向が開通状態となっても、その情報を停止中の車両に伝達することができず、この停止状態を解除するためには、運転者が目視で分岐器の転換を確認しなければならない問題がある。このため、分岐器転換の誤認という人為的ミスを誘発する可能性があった。また、当該システムは、分岐器前端からの進入には対処できず、異線進入を防止する手段を有しないものである。
更に、当該システムでは、車体下部に設置する車上子がコントローラー等と電気的に接続される必要があり、その設置位置を可変にすることができないため、保守用車がその前後にレール運搬台車等を連接して走行する場合、制動開始時の車両の進行方向先端位置が一定でなく、前方への連接が長い場合には、進行速度によっては、制動が間に合わなくなる恐れがあった。
この問題を解決するため、本件発明者らは、特願２００２−３０６５４１において、下記の発明を提案した。即ち、該保守用車進路確認装置の設置された分岐器に関し、保守用車の前後端に隣接線路まで到達しない極めて低出力の検知用送信機と、該検知用送信機を搭載した保守用車が、当該検知用送信機から電波を送信しつつ、分岐器に接近する場合に、保守用車の制動に必要な距離だけ分岐器から離れた軌間内に設置し、その送信電波を受信して該保守用車の通過位置情報を取得する検知用受信機と、その通過位置情報と該保守用車進路確認装置から得られる分岐器の開通方向に関する情報を該保守用車に対し送信する地上送信機及び保守用車内に設置し、該地上送信機からの情報から、該保守用車の進行方向が開通状態（進行可能）か非開通状態（進行不可能）かを判断し、進行方向が非開通時には、警告表示と共に制動信号を送出し、保守用車に非常制動をかけさせる車内受信箱から成る保守用車分岐器停止装置を提案した。
この提案では、保守用車に取付ける検知用送信機は、バッテリーによる独立電源方式とし、取付け、取外しが容易な構造とすることにより、該保守用車がその前後にレール運搬台車等を連接して走行する場合、該連接部の最先端及び最後端に取付けて走行できるものとしている。これにより、保守用車の制動開始位置が常に一定に保持できるため、制動が遅れて割り出し事故となる心配が無くなると共に、該保守用車に対し送信する地上送信機に特定小電力無線機を使用することにより、該保守用車の進行方向が非開通のため強制停止した場合にも、分岐器の転換情報の伝達が容易となり、運転者の目視確認に頼ることなく、制動を解除できるものとなった。
実開平３−５０６０１号公報特開平７−２１５２１５号公報特開平９−４８３４８号公報特開平１１−２２７６０４号公報特開平１１−２２７６０６号公報 Conventionally, when a maintenance vehicle is run for maintenance and inspection on a railway track equipped with a turnout, especially when turning at night, it is difficult to determine the opening direction by the tongrail part of the turnout. The maintenance vehicle stopped once before the device, and the supervisor got off the maintenance vehicle and checked the opening direction, and then the maintenance vehicle was running. It takes time to check the direction and run the vehicle for maintenance, and not only the work efficiency is bad, but there is also a risk of driving in a different line due to misidentification of the opening direction or causing an indexing accident. It was.
In order to solve this problem, Patent Document 1 proposes a method of displaying the opening direction with a display board that rotates in conjunction with the change of the tongler part of the branching device. The method was unsatisfactory because of its complicated mechanism and difficult to see at night.
Therefore, the inventors of the present invention have an independent power source with a solar battery and a storage battery, and detect the movement of the Tongleil part with a changeover switch, whereby the opening direction of the branching device is placed on a sleeper like a guide light on a runway. Patent Document 2 has already proposed a maintenance vehicle route confirmation device that causes several double-sided light emitting display devices (built-in light emitting diodes) to flash and emit light, thereby clearly indicating the opening direction of the branching device.
This device is equipped with a transmitter in the maintenance car, and when this maintenance car is transmitting radio waves at night and approaches the branching device, only when the receiver installed beside the branching device receives the radio wave, The illuminator in the opening direction installed on the sleepers flashes and emits light to inform the driver of the maintenance vehicle of the opening direction of the branching device. By using this device, the opening direction of the branching device is changed to the maintenance vehicle. Therefore, the maintenance vehicle can be operated more efficiently.
Further, in order to prevent an oversight by a driver or an indexing accident due to misidentification, Patent Documents 3 to 5 propose an indexing prevention device having an automatic stop function using radio waves.
However, the above-mentioned index prevention device has a short information transmission distance, and only when the vehicle upper element mounted on the maintenance vehicle passes directly above the ground element installed on the sleeper on the ground, the opening information of the branching device is obtained. If the direction of travel of the branching device stops because it cannot be transmitted, the stop position of the maintenance vehicle will pass the position of the ground unit, the branching device will be changed, and the traveling direction will be open. However, the information cannot be transmitted to the stopped vehicle, and there is a problem that the driver must visually confirm the switching of the branching device in order to cancel the stopped state. For this reason, there was a possibility of inducing a human error such as misidentification of switching of the branching device. Moreover, the said system cannot cope with the approach from the front end of a branching device, and does not have a means for preventing a different line approach.
Furthermore, in this system, since the vehicle upper part to be installed at the lower part of the vehicle body needs to be electrically connected to a controller or the like, and the installation position cannot be made variable, the maintenance vehicle is placed on the rail transport carriage before and after it. When the vehicle travels in a connected manner, the front end position of the vehicle in the traveling direction at the start of braking is not constant, and if the forward connection is long, depending on the traveling speed, there is a risk that braking may not be in time.
In order to solve this problem, the present inventors proposed the following invention in Japanese Patent Application No. 2002-306541. That is, with respect to the branching device in which the maintenance vehicle route confirmation device is installed, a very low output detection transmitter that does not reach the adjacent line at the front and rear ends of the maintenance vehicle, and a maintenance vehicle equipped with the detection transmitter However, when transmitting a radio wave from the transmitter for detection and approaching the branching device, install it in the gauge separated from the branching unit by a distance necessary for braking the maintenance vehicle, and receive the transmission radio wave. A receiver for detecting the passing position information of the maintenance vehicle, and a ground transmission for transmitting the passing position information and information on the opening direction of the branching device obtained from the maintenance vehicle route confirmation device to the maintenance vehicle. Installed in the aircraft and the maintenance vehicle, and from the information from the ground transmitter, it is determined whether the traveling direction of the maintenance vehicle is an open state (can proceed) or a non-open state (cannot proceed). When opening, a warning signal is sent with a warning signal for maintenance. Has proposed a maintenance car splitter stop device made from the inside of the vehicle inbox to let multiplied by the emergency braking to.
In this proposal, the detection transmitter attached to the maintenance vehicle is an independent power source system using a battery, and the structure is such that the maintenance vehicle can be easily attached and removed, so that the maintenance vehicle is connected to the rail transport carriage and the like before and after. When traveling, it is assumed that the vehicle can travel by being attached to the leading end and the rearmost end of the connecting portion. As a result, the braking start position of the maintenance vehicle can be kept constant at all times, so there is no risk of an indexing accident due to braking delay, and a specific low-power radio is used for the ground transmitter that transmits to the maintenance vehicle. Therefore, even when the traveling direction of the maintenance vehicle is forcibly stopped due to non-opening, the transfer information of the branching device can be easily transmitted, and braking can be released without relying on the driver's visual confirmation. became.

しかし乍ら、上記提案の装置では、地上送信機からの上記２つの情報を含む送信電波が近隣を走行中の全ての保守用車に到達してしまい正しい制御を狂わせる惧れがあり、或いは、逆に、隣接の保守用車を制御する地上送信機からの上記２の情報を含む送信電波を受信し、正しい制御を狂わせられる惧れがある。例えば、その送信電波の到達範囲内、例えば約２００ｍ程度の範囲内で作業中の保守用車が複数存在する場合は、互いにその各保守用車に不要な制動や制動解除がかゝってしまう可能性がある他、進行方向が非開通で保守用車は停止している場合に、実際には非開通のままであるにも拘らず、車内の受信機が他分岐の転換情報を受信して、恰も進行方向の分岐器が転換し、進行方向が開通状態となったかのような表示に切り替わり、制動が解除できる状態になってしまうなどの問題が、極めて稀なケースではあるが、起こり得る可能性がある。
本願の発明は、上記提案に係る保守用車分岐器停止装置の上記課題を解決するべく、当該分岐器を通過する保守用車に搭載した車内受信箱に固有の識別情報を付与することにより、該地上送信機からの自己の識別情報を含む正しい情報電波は読み取り受信可能であるが、近隣を走行する他の保守用車からの識別情報を含まない従来の情報電波及び他の保守用車に付与した固有の識別情報を含む情報電波は受信できないようにし、更には、自己の情報電波は隣接の保守用車に受信されないようにし、常に正しい動作を保証する保守用車分岐器停止装置を提供することを目的としたものである。 However, in the proposed apparatus, there is a possibility that the transmission radio wave including the above two pieces of information from the ground transmitter may reach all maintenance vehicles traveling in the vicinity and upset the correct control, or On the contrary, there is a possibility that the transmission control including the above-mentioned information 2 from the ground transmitter that controls the adjacent maintenance vehicle is received and correct control is distorted. For example, when there are a plurality of maintenance vehicles in operation within the reach of the transmission radio wave, for example, within a range of about 200 m, each of the maintenance vehicles is subject to unnecessary braking and braking release. In addition, when the direction of travel is not open and the maintenance vehicle is stopped, the receiver in the vehicle receives the conversion information of the other branch even though it is actually not open. However, problems such as the switch in the direction of travel switching to the display as if the direction of travel has been opened, and the state where the braking can be released are possible in a rare case, but may occur. there is a possibility.
In order to solve the above-mentioned problem of the maintenance vehicle branching device stopping device according to the above proposal, the invention of the present application gives unique identification information to the in-vehicle inbox mounted on the maintenance vehicle that passes through the branching device. The correct information radio wave including the identification information of the self from the ground transmitter can be read and received, but the conventional information radio wave and other maintenance vehicles not including the identification information from other maintenance vehicles traveling in the vicinity Providing a maintenance vehicle branching device stop device that prevents the reception of information radio waves including the given unique identification information, and prevents the reception of its own information radio waves by the adjacent maintenance vehicle, and always guarantees correct operation. It is intended to do.

FIG. 1 is an explanatory view showing a maintenance vehicle course confirmation device known in Patent Document 2. FIGS. 1 and 2 are a straight course A and a straight path A which are switched between a straight path A and a branch path B by a tongue rail C. FIG. Shows a state where is opened, and a state where the branch path B is opened. A plurality of double-sided light emitting type display devices 1 with built-in light emitting diodes that can be confirmed simultaneously from the front end direction X and the rear end direction Y of the branching device are arranged at appropriate intervals in the track at the rear position of the tongrel part C in the straight path A.

They are arranged in series.

本例では、３個の表示器を約２ｍの間隔で配置した場合を示している。前記トングレール部Ｃには、その切り換え作動に連動して、電気回路を切り換える切り換えスイッチ３，４が配置にあると共に、該トングレール部Ｃの位置の側方の軌道外には、後述する制御部５を配置し、該制御部５と各表示器１及び２とは、図示しないが切り換え用の切り換えスイッチ３，４を介して電気的に接続されている。なお、前記切り替えスイッチ３，４として、リミットスイッチの他に、磁気近接スイッチ等も使用可能である。 In this example, the case where three displays are arranged at intervals of about 2 m is shown.

図３は、保守用車Ｄの正面図を示しており、該保守用車Ｄの屋上には、アンテナ６と送信機７から成る送信部が架台８により搭載設置され、且つ、前記送信機７は、運転者が送信の制御をするための手元スイッチ９と電気的に接続している。 FIG. 3 shows a front view of the maintenance vehicle D. On the roof of the maintenance vehicle D, a transmission unit including an antenna 6 and a transmitter 7 is mounted and installed by a mount 8, and the transmitter 7 is installed. Is electrically connected to a hand switch 9 for the driver to control transmission.

図４は、前記制御部５を示しており、箱体１０とこれを地上に支持する支柱１１とアンテナ１２から成り、前記箱体１０の内部には、受信機１３と蓄電池１４と制御回路１５が内蔵され、更に、前記箱体１０の上部には、太陽電池１６が約４５度の角度で設置されている。 FIG. 4 shows the control unit 5, which includes a box 10, a column 11 that supports the box 10, and an antenna 12. A receiver 13, a storage battery 14, and a control circuit 15 are provided inside the box 10. And a solar cell 16 is installed at an upper portion of the box 10 at an angle of about 45 degrees.

次に上記した保守用車進路確認装置の作動について説明する。
日中は、太陽の光を受けて太陽電池１６が発電し、この発電により蓄電池１４を充電する。日没後、前記太陽電池１６の発電電圧が一定レベルまで低下した時点で蓄電池１４により、該受信機１３は受信可能状態となる。この状態において、軌道上を走行する前記保守用車Ｄが、これに搭載した送信機７から電波を送信しつつ前記制御部５に接近すると、到達電波が一定のレベルに達した時点、例えば制御部５から１００ｍ離れた時点で、前記受信機１３は受信状態となり、前記制御回路１５で点滅信号を発生する。この点滅信号が、前記切り換えスイッチ３，４を経由し、分岐器の開通している方向に配置した該表示器１又は２を点滅発光させる。即ち直進路Ａが開通している図１の場合には、表示器１を点滅発光させ、分岐路Ｂが開通している図２の場合には、表示器２を点滅発光させ、これによって、保守用車Ｄの運転者が該分岐器の開通方向を識別できる。
前記分岐器の通過後、前記保守用車Ｄが前記分岐器から遠ざかり、該送信機７からの送信電波を該受信機１３で受信できなくなると、表示器１，２の点滅発光が停止する。 Next, the operation of the above-described maintenance vehicle course confirmation device will be described.
During the daytime, the solar cell 16 generates power in response to the sunlight, and the storage battery 14 is charged by this power generation. After sunset, when the power generation voltage of the solar cell 16 drops to a certain level, the storage battery 14 makes the receiver 13 ready for reception. In this state, when the maintenance vehicle D traveling on the track approaches the control unit 5 while transmitting radio waves from the transmitter 7 mounted on the track, the time when the arrival radio waves reach a certain level, for example, control At a time 100 m away from the unit 5, the receiver 13 is in a receiving state, and the control circuit 15 generates a blinking signal. This blinking signal causes the indicator 1 or 2 arranged in the direction in which the branching unit is opened via the change-over switches 3 and 4 to blink. That is, in the case of FIG. 1 in which the straight path A is opened, the display 1 is flashed and emitted, and in the case of FIG. 2 in which the branch path B is opened, the indicator 2 is flashed and emitted. The driver of the maintenance vehicle D can identify the opening direction of the branching device.
After passing through the branching device, when the maintenance vehicle D moves away from the branching device and the transmission radio wave from the transmitter 7 cannot be received by the receiver 13, the flashing light emission of the displays 1 and 2 stops.

一方、直進路Ａ及び分岐路Ｂの夫々の分岐器の後端方向Ｙ、Ｚには、トングレール部Ｃの先端位置から保守用車の所要制動距離Ｌ2 以上、例えば６０ｍ以上離れた位置の軌道内に、検知用アンテナ１８，１９が夫々配置してあり、該検知用アンテナ１８，１９から数ｍ離れた位置の直進路Ａと分岐路Ｂに挟まれた軌道外に、前記検知用アンテナ１８，１９と電気的に接続された検知用受信機２１が配置してあり、この検知用受信機２１から約３０ｍ離れた分岐器に近い位置の直進路Ａと分岐路Ｂに挟まれた軌道外には、地上送信機２３を配置し、該地上送信機２３は、前記検知用受信機２１と電気的に接続されていると共に、該分岐器の脇に設置した前記保守用車進路確認装置Ｐにおける制御部５の近くに設置する前記システム制御箱２４に対しても電気的に接続され、従って、分岐器の開通方向情報は、システム制御箱２４を介し、地上送信機２２，２３に伝送される。尚、地上送信機２２，２３は、システム制御箱２４内に収納しても良い。 On the other hand, in the rear end directions Y and Z of the turnouts of the straight path A and the branch path B, the track is located at a position more than the required braking distance L2 of the maintenance vehicle, for example, 60 m or more, from the front end position of the tongrail part C. In addition, detection antennas 18 and 19 are arranged respectively, and the detection antenna 18 is out of the track sandwiched between the straight path A and the branch path B at a position several m away from the detection antennas 18 and 19. , 19 and a detection receiver 21 that is electrically connected to the detection receiver 21 is located outside the orbit between the straight path A and the branch path B at a position close to the branching device about 30 m away from the detection receiver 21.

In the system control box 24 installed near the control unit 5 in Also electrically connected to, thus, opening direction information of the splitter is through a system control box 24, it is transmitted to the ground transmitter 22. The ground transmitters 22 and 23 may be housed in the system control box 24.

また、保守用車Ｄにおいては、如何なる連結形態においても、その編成の最前端と最後端とに、隣接線路まで到達しない極めて低出力の検知用送信機２５，２６が夫々配設してあり、この検知用送信機２５，２６は乾電池または太陽電池と蓄電池の組合せから成る独立した電源部を有しており、これが、保守用車に対し、容易に取付け、取出し可能な構成となっている。 Further, in the maintenance vehicle D, in any connection form, extremely low output detection transmitters 25 and 26 that do not reach the adjacent line are arranged at the front end and the rear end of the formation, respectively. Each of the transmitters 25 and 26 for detection has an independent power supply unit composed of a dry battery or a combination of a solar battery and a storage battery, and is configured to be easily attached to and taken out from a maintenance vehicle.

また、前記保守用車Ｄの車内には、後述するように、電源部及び制動装置と電気的に接続された車内受信箱２７が配置してある。この車内受信箱２７には、地上送信機２２，２３からの送信電波を受信する受信機と保守用車の制動を作動する作動回路が内蔵されており、更に、本発明によれば、該車内受信箱２７内の受信機に当該保守用車Ｄに固有の識別情報を付与し、検知用送信機２５，２６から送信する電波情報に車内受信箱２７内の受信機に当該識別情報を含ませるようにしたことを特徴構成とする。識別情報としては、識別番号、識別信号、識別符号などが使用されるが、この実施例では識別番号を使用した実施例で以下説明する。前記車内受信箱２７は所要の手段により、例えば箱裏面の装着した強力磁石により保守用車の壁面に取付けられる。
車内受信箱２７は、図７に示すように、箱表面に表示用赤色発光ランプ２８と表示用緑色発光ランプ２９、右側選択ボタン３０、左側選択ボタン３１、警報ブザー３２、確認ボタン３３、後進ボタン３４及び電源ボタン３７が配置され、箱側面には車内電源との接続コネクタ３５及び保守用車制動装置との接続コネクタ３６が配置されており、該車内電源との接続コネクタ３５を介し、該保守用車の車内電源(直流２４Ｖ)と、また、該保守用車制動装置との接続コネクタ３６を介して、該保守用車制動装置と夫々電気的に接続されている。 Further, as will be described later, an in-vehicle reception box 27 that is electrically connected to the power supply unit and the braking device is disposed in the maintenance vehicle D. This in-car receiving box 27 has a built-in receiver for receiving transmission radio waves from the ground transmitters 22 and 23 and an operating circuit for operating braking of the maintenance vehicle. Identification information unique to the maintenance vehicle D is given to the receiver in the reception box 27, and the identification information is included in the receiver in the reception box 27 in the radio wave information transmitted from the detection transmitters 25 and 26. This is the characteristic configuration. As the identification information, an identification number, an identification signal, an identification code, and the like are used. In this embodiment, an embodiment using an identification number will be described below. The in-vehicle reception box 27 is attached to the wall surface of the maintenance vehicle by a required means, for example, a strong magnet mounted on the back of the box.
As shown in FIG. 7, the in-car receiving box 27 has a display red light-emitting lamp 28 and a display green light-emitting lamp 29, a right selection button 30, a left selection button 31, an alarm buzzer 32, a confirmation button 33, a reverse button on the box surface. 34 and a power button 37 are disposed, and a connector 35 for connection to the in-vehicle power source and a connection connector 36 for a maintenance vehicle braking device are disposed on the side of the box, and the maintenance is performed via the connection connector 35 for the in-vehicle power source. The maintenance vehicle braking device is electrically connected to the maintenance vehicle braking device via a connection connector 36 connected to the in-vehicle power source (DC 24V) of the maintenance vehicle and the maintenance vehicle braking device.

次に、上記した構成の動作について説明する。
既に詳述したように、夜間、保守用車進路確認装置Ｐにおいて、制御部５が蓄電池１４により受信可能状態となり、これによって制御部５と電気的に接続しているシステム制御箱２４を介しての検知用受信機２０，２１及び地上送信機２２，２３も作動可能状態となる。 Next, the operation of the above configuration will be described.
As already described in detail, in the maintenance vehicle route confirmation device P at night, the control unit 5 becomes receivable by the storage battery 14, thereby via the system control box 24 electrically connected to the control unit 5. The detection receivers 20 and 21 and the ground transmitters 22 and 23 are also operable.

この状態において、保守用車Ｄが、図５で示すように、分岐器の前端方向Ｘから進入すると、進行方向の前端の検知用送信機２６が該検知用アンテナ１７の直上を通過すると同時に、検知用受信機２０が前記検知用送信機２６の電波を受信し、保守用車Ｄの通過位置情報として地上送信機２２へ伝達する。このとき、検知用送信機から送信する電波には、後述する車内受信箱２７に内蔵する受信機の固有の識別番号と１対１に対応する識別番号を含むこととなる。かくして、該地上送信機２２へ、該車内受信箱２７内蔵の受信機の持つ固有の識別番号が伝達される。すると、該地上送信機２２は、保守用車Ｄに対し、この固有の識別番号を含む通過位置情報と、既に述べたように、前記システム制御箱２４を介して受容している分岐器の開通方向情報とを同時に送信し、この地上送信機２２からの送信電波は、該保守用車Ｄの車内受信箱２７に内蔵の受信機で受信される。この時、該受信機は最初に、受信電波に含まれる識別番号を読み取る。これにより、近隣の軌道を走行中の保守用車の情報のみで識別番号を含まない送信電波は受信されないので、これによる誤った制動や制動解除は防止される。
また、本発明によれば、図示の当該保守用車の近隣に少なくとも一台又は複数台の保守用車が在るときは勿論、その夫々の保守用車の受信機に夫々固有の識別番号を付与せしめ、夫々の送信電波に夫々固有の識別番号を含ませるようにしたので、各保守用車において、その隣接の保守用車からの固有の識別番号を含む送信電波情報は、その識別番号が一致しないので、その誤った情報が受信されることがなく、自己の固有の識別番号を含む送信電波受信機に付与した固有の識別番号が一致した場合にのみ、換言すれば、自己が固有の識別番号を含む送信電波を受信したときにのみ、通過位置情報と分岐器の開通方向情報を読み取ることができるので、各保守用車は、常に、近隣から来る電波情報の受信により誤動作を生じないと共に、隣接の保守用車へ誤動作を与えない。 In this state, as shown in FIG. 5, when the maintenance vehicle D enters from the front end direction X of the branching unit, the detection transmitter 26 at the front end in the traveling direction passes immediately above the detection antenna 17, The detection receiver 20 receives the radio wave of the detection transmitter 26 and transmits it to the ground transmitter 22 as passing position information of the maintenance vehicle D. At this time, the radio wave transmitted from the detection transmitter includes a unique identification number of a receiver built in the in-vehicle reception box 27 described later and an identification number corresponding to the one-to-one correspondence. Thus, a unique identification number of the receiver built in the in-vehicle reception box 27 is transmitted to the ground transmitter 22. Then, the terrestrial transmitter 22 opens, for the maintenance vehicle D, the passing position information including the unique identification number and the branching device received via the system control box 24 as described above. Direction information is transmitted at the same time, and the transmission radio wave from the ground transmitter 22 is received by a receiver built in the in-vehicle reception box 27 of the maintenance vehicle D. At this time, the receiver first reads the identification number included in the received radio wave. As a result, transmission information including only information on a maintenance vehicle traveling on a nearby track and not including an identification number is not received, thereby preventing erroneous braking and braking cancellation.
In addition, according to the present invention, when there is at least one or more maintenance vehicles in the vicinity of the illustrated maintenance vehicle, a unique identification number is assigned to each of the maintenance vehicle receivers. Since each transmission radio wave includes a unique identification number, the transmission radio wave information including the unique identification number from the adjacent maintenance car is the same as that of each maintenance car. Since it does not match, the incorrect information will not be received, and only when the unique identification number assigned to the transmitting radio wave receiver including its own unique identification number matches, in other words, Only when the transmission radio wave including the identification number is received, the passing position information and the opening direction information of the branching device can be read, so that each maintenance vehicle does not always malfunction due to reception of radio wave information coming from nearby. Along with the adjacent It does not give the malfunction to use the maintenance vehicles.

該受信電波内の識別番号の整合が取れると、該車内受信箱２７（図７に明示）の直進路用の右側選択ボタン３０と分岐器用の左側選択ボタン３１が同時に点滅発光すると同時に警報ブザー３２を間欠鳴動する。この状態は、該保守用車Ｄが分岐器の前端方向Ｘから進入していることを示し、該保守用車Ｄの運転者が、これから進行しようとする方向の選択ボタン３０又は３１を選択して押すまで継続する。例えば、前記分岐器において、図１で示すように、直進路Ａが開通状態にあるとき、この状態は、該分岐器の前端方向Ｘから見て右側が開通していることとなり、この時、右側選択ボタン３０を押すと、警報ブザー３２の間欠鳴動が停止し、左側選択ボタンが消灯すると共に、右側選択ボタンが連続点灯となる。この状態は、該分岐器の開通方向と該保守用車Ｄの進行希望方向が整合した正常状態にあるので、前記車内受信箱２７の表示用緑色発光ランプ２９が点灯すると共に制動装置が作動せず、従って保守用車Ｄには非常制動は掛からず、そのまま進行できる。 When the identification numbers in the received radio waves are matched, the right-hand selection button 30 for the straight path and the left-hand selection button 31 for the branching device of the in-vehicle reception box 27 (shown in FIG. 7) simultaneously flash and emit light, and at the same time, the alarm buzzer 32 Sounds intermittently. This state indicates that the maintenance vehicle D is approaching from the front end direction X of the turnout, and the driver of the maintenance vehicle D selects the selection button 30 or 31 for the direction to proceed from now on. Until you press it. For example, in the branching device, as shown in FIG. 1, when the straight path A is in an open state, this state means that the right side as viewed from the front end direction X of the branching device is open. When the right selection button 30 is pressed, the intermittent sounding of the alarm buzzer 32 is stopped, the left selection button is turned off, and the right selection button is continuously lit. This state is a normal state in which the opening direction of the branching device and the desired traveling direction of the maintenance vehicle D are aligned, so that the display green light-emitting lamp 29 of the in-vehicle reception box 27 is turned on and the braking device is operated. Therefore, emergency braking is not applied to the maintenance vehicle D, and the vehicle can proceed as it is.

上記に対し、前記分岐器により、図２に示すように、分岐路Ｂが開通状態にあるとき、この状態は、該分岐器の前端方向Ｘから見て左側が開通していることとなり、この時、右側選択ボタン３０を押すと、警報ブザー３２は連続鳴動に変わり、左側選択ボタンが消灯すると共に、右側選択ボタンが連続点灯する。同時にこの状態は、該分岐器の開通方向と該保守用車Ｄの進行希望方向が不整合の異常状態となる。従って、車内受信箱２７の表示用赤色発光ランプ２８が点灯すると共に制動装置が作動して、前記保守用車Ｄに非常制動が掛かり停止する。 On the other hand, when the branch path B is in an open state as shown in FIG. 2 by the branching device, this state means that the left side as viewed from the front end direction X of the branching device is open. When the right selection button 30 is pressed, the alarm buzzer 32 changes to continuous sound, the left selection button is turned off, and the right selection button is lit continuously. At the same time, this state becomes an abnormal state in which the opening direction of the branching device and the desired traveling direction of the maintenance vehicle D are mismatched. Accordingly, the display red light-emitting lamp 28 of the in-vehicle receiving box 27 is turned on and the braking device is operated, and the maintenance vehicle D is emergency braked and stopped.

この停止状態は、次に前記分岐器が転換されるまで継続する。そして前記分岐器が転換され、直進路Ａが開通状態になった時点で、分岐器転換情報即ち分岐器の新たな開通方向情報を先に得た該識別番号と共に地上送信機２２から送信する。これを車内受信箱２７で受信すると、該受信機は最初に、受信電波に含まれる識別番号を読み取り、その識別番号と、該受信機固有の識別番号を比較し、両者が整合した場合にのみ、分岐器の開通方向情報を読み取り、該車内受信箱２７の表示が次のとおりに変化する。即ち、警報ブザー３２の連続鳴動が間欠鳴動に変化すると同時に、表示用赤色発光ランプ２８が消灯し、表示用緑色発光ランプ２９が点灯すると共に、確認ボタン３３が点滅を開始する。この状態では依然として保守用車Ｄの制動は解除されず、該保守用車Ｄは停止した状態におかれる。 This stop state continues until the turnout is next switched. When the branching unit is switched and the straight path A is opened, branching unit switching information, that is, new opening direction information of the branching unit is transmitted from the ground transmitter 22 together with the identification number obtained previously. When this is received by the in-car inbox 27, the receiver first reads the identification number included in the received radio wave, compares the identification number with the identification number unique to the receiver, and only when both match. Then, the opening direction information of the branching unit is read, and the display of the in-vehicle reception box 27 changes as follows. That is, simultaneously with the continuous sounding of the alarm buzzer 32 changing to intermittent sounding, the display red light-emitting lamp 28 is turned off, the display green light-emitting lamp 29 is turned on, and the confirmation button 33 starts blinking. In this state, the braking of the maintenance vehicle D is not released yet, and the maintenance vehicle D is in a stopped state.

この状態で点滅発光中の前記確認ボタン３３を押すと、警報ブザー３２の間欠鳴動が停止すると同時に、制動装置の作動が解除され、保守用車Ｄの進行を開始することができ、これにより、保守用車の異線進入を未然に防止することができる。次いで、保守用車Ｄが前記分岐器を通過し、分岐器の後端に設置した検知用アンテナ１８又は１９上を通過すると、地上のシステムがクローズすると共に、地上送信機２３よりシステムクローズ信号が送信され、これを前記車内送信箱２７で受信すると、車内受信箱２７の全ての表示が全てリセットされる。 When the confirmation button 33 that is blinking and emitting light is pressed in this state, the intermittent sounding of the alarm buzzer 32 is stopped, and at the same time, the operation of the braking device is canceled and the maintenance vehicle D can start to proceed. It is possible to prevent a maintenance vehicle from entering another line. Next, when the maintenance vehicle D passes through the branching unit and passes over the detection antenna 18 or 19 installed at the rear end of the branching unit, the ground system is closed and a system close signal is sent from the ground transmitter 23. When it is transmitted and received by the in-vehicle transmission box 27, all the displays in the in-vehicle reception box 27 are reset.

次に、図６で示すように、保守用車Ｄが分岐器の後端方向Ｙから進入する場合の動作を説明する。即ち保守用車Ｄが終端方向Ｙから進入すると、保守用車Ｄの進行方向の前端の検知用送信機２５が該検知用アンテナ１８の直上を通過すると同時に、検知用受信機２１が前記検知用送信機２５の電波を受信し、保守用車Ｄの通過位置情報として地上送信機２３へ伝達する。このとき、先に述べたように、検知用送信機２５、２６から送信する電波に、当該保守用車Ｄに固有の識別情報を含んでいるので、これにより、検知用送信機２５から該地上送信機２３へ、当該保守用車Ｄの持つ固有の識別番号が伝達される。 Next, as shown in FIG. 6, the operation when the maintenance vehicle D enters from the rear end direction Y of the branching device will be described. That is, when the maintenance vehicle D enters from the end direction Y, the detection transmitter 25 at the front end in the traveling direction of the maintenance vehicle D passes immediately above the detection antenna 18, and at the same time, the detection receiver 21 detects the detection vehicle 21. The radio wave of the transmitter 25 is received and transmitted to the ground transmitter 23 as passing position information of the maintenance vehicle D. At this time, as described above, since the radio waves transmitted from the detection transmitters 25 and 26 include identification information unique to the maintenance vehicle D, this allows the detection transmitter 25 to detect the ground. A unique identification number of the maintenance vehicle D is transmitted to the transmitter 23.

すると、前記地上送信機２３は、前記保守用車Ｄに対し、この固有の識別番号を含む通過位置情報と、前記システム制御箱２４を介して既に受容している分岐器の開通方向情報を同時に送信し、この地上送信機２３からの送信電波は、前記保守用車Ｄの車内受信箱２７に内蔵の受信機で受信される。この時、該受信機は最初に、受信電波に含まれる識別番号を読み取り、その識別番号と、当該受信機を搭載の保守用車Ｄに固有の識別番号を比較し、両者が整合即ち、一致した場合にのみ、通過位置情報と分岐器の開通方向情報を読み取ることができるようにしたので、該分岐器を通過中の当該保守用車Ｄにのみ、該分岐器の情報が伝達され、近隣からの誤った情報を含む送信電波の受信を防止し、常に正しい制動又は制動解除などの制御が保証される。また、近隣を走行中の保守用車には、当該保守用車Ｄの固有の識別番号とは異なる、要するに、固有の識別番号を付与されているため、夫々の保守用車には、互いに異なる情報は伝達されないので、夫々不要な制動や、分岐器転換情報の誤報が防止でき、常に、各保守用車を正しい情報で制御できる。 Then, the ground transmitter 23 simultaneously transmits the passing position information including the unique identification number to the maintenance vehicle D and the opening direction information of the branching device already received via the system control box 24. The transmitted radio wave from the ground transmitter 23 is received by a receiver built in the in-vehicle reception box 27 of the maintenance vehicle D. At this time, the receiver first reads the identification number included in the received radio wave, compares the identification number with the identification number unique to the maintenance vehicle D on which the receiver is mounted, and the two match or match. Since the passage position information and the branching direction information of the branching device can be read only in the case of the failure, the information on the branching device is transmitted only to the maintenance vehicle D passing through the branching device. Therefore, it is possible to prevent the reception of the transmission radio wave including erroneous information from the vehicle and to always ensure the correct control such as braking or braking release. In addition, since the maintenance vehicle running in the vicinity is assigned a unique identification number that is different from the unique identification number of the maintenance vehicle D, the maintenance vehicles are different from each other. Since no information is transmitted, unnecessary braking and misinformation of branch switch change information can be prevented, and each maintenance vehicle can always be controlled with correct information.

受信電波内の識別番号の整合を読み取れると、例えば、前記分岐器において、図１で示すように、直進路Ａが開通状態にあるとき、この状態は、該保守用車Ｄの進行方向が開通している状態であるので、前記車内受信箱２７の表示用緑色ランプ２９が点灯し、且つ、保守用車Ｄの制動装置は作動せず、そのまま進行できる。これに対し、前記分岐器において、図２で示すように、分岐路Ｂが開通状態にあるとき、この状態は、保守用車Ｄの進行方向が非開通の状態で、異常状態である。 When the matching of the identification number in the received radio wave can be read, for example, when the straight road A is in the open state in the branching unit as shown in FIG. 1, this state indicates that the traveling direction of the maintenance vehicle D is open. In this state, the display green lamp 29 of the in-vehicle reception box 27 is turned on, and the brake device of the maintenance vehicle D does not operate and can proceed as it is. On the other hand, as shown in FIG. 2, in the branching device, when the branch path B is in an open state, this state is an abnormal state in which the traveling direction of the maintenance vehicle D is not open.

この状態で、前記車内受信箱２７の警報ブザー３２が連続鳴動すると共に、表示用赤色発光ランプ２８が点灯し、且つ異常信号により、前記保守用車Ｄの制動装置が作動して非常制動が掛かり停止し、この停止状態は、次に該分岐器が転換されるまで継続する。前記分岐器が転換され、直進路Ａが開通状態になった時点で、該地上送信機２３から分岐器転換情報即ち新たな開通方向情報を先に得た識別番号と共に送信する。これを車内受信箱２７で受信すると、該受信機は最初に、受信電波に含まれる識別番号を読み取り、その識別番号と、該保守用車Ｄに固有の識別番号を比較し、両者が整合した場合にのみ、通過位置情報と分岐器の開通方向情報を読み取り、該車内受信箱２７は次のとおりに作用する。 In this state, the alarm buzzer 32 of the in-car reception box 27 is continuously sounded, the display red light-emitting lamp 28 is turned on, and the brake device of the maintenance vehicle D is activated by the abnormal signal, and emergency braking is applied. Stop and this stop condition will continue until the turnout is next switched. When the branching unit is switched and the straight path A is opened, the branch transmitter switching information, that is, new opening direction information is transmitted from the ground transmitter 23 together with the previously obtained identification number. When this is received by the in-car inbox 27, the receiver first reads the identification number included in the received radio wave, compares the identification number with the identification number unique to the maintenance vehicle D, and the two match. Only in this case, the passing position information and the branching direction information are read, and the in-vehicle receiving box 27 operates as follows.

即ち、警報ブザー３２の連続鳴動が間欠鳴動に変化すると同時に、表示用赤色発光ランプ２８が消灯し、表示用緑色発光ランプ２９が点灯すると共に、確認ボタン３３が点滅を開始する。この状態では、前記保守用車Ｄの制動は解除されず、停止したままにおかれるが、この状態で点滅発光中の該確認ボタン３３を押すと、警報ブザー３２の間欠鳴動が停止すると同時に、制動装置が解除され、保守用車Ｄの進行が開始できる。 That is, simultaneously with the continuous sounding of the alarm buzzer 32 changing to intermittent sounding, the display red light-emitting lamp 28 is turned off, the display green light-emitting lamp 29 is turned on, and the confirmation button 33 starts blinking. In this state, braking of the maintenance vehicle D is not released and is left stopped, but when the confirmation button 33 that is flashing and emitting light is pressed in this state, the intermittent sounding of the alarm buzzer 32 stops, The braking device is released and the maintenance vehicle D can start to travel.

次いで、保守用車Ｄが分岐器を通過し、分岐器の前端位置に設置した検知用アンテナ１７上を通過すると、地上のシステムがクローズすると共に、地上送信機２２よりシステムクローズ信号が送信され、該車内受信箱２７で受信すると、該車内受信箱２７の全ての表示がリセットされる。
上記した作用は、保守用車Ｄが分岐器後端方向Ｚから進入する場合も同様である。 Next, when the maintenance vehicle D passes through the branching unit and passes over the detection antenna 17 installed at the front end position of the branching unit, the ground system is closed and a system close signal is transmitted from the ground transmitter 22. When receiving in the in-vehicle reception box 27, all the displays in the in-vehicle reception box 27 are reset.
The above operation is the same when the maintenance vehicle D enters from the branching device rear end direction Z.

次に、保守用車Ｄが分岐器後端Ｙ又はＺから進入し、分岐器を通過後、分岐器の前端位置に設けた検知用受信アンテナ１７上を通過する前に、後進する場合の動作を説明する。
即ち保守用車Ｄが、分岐器の後端方向Ｙ又はＺから進入し、該分岐器を通過した後、その前端位置に設置した検知用受信アンテナ１７上を通過する前に後進する場合、保守用車Ｄを一旦停車させる。この状態で車内受信箱２７の後進ボタン３４を押すと、前記車内受信箱２７の右側選択ボタン３０と左側選択ボタン３１とが同時に点滅発光すると共に、警報ブザー３２を間欠鳴動する。この動作は、確認ボタン３４が点灯することを除き、分岐器の前端方向Ｘから進入する場合と同様の動作であり、以降、分岐器の前端方向Ｘからの進入時と同様の動作を行う。 Next, the operation in the case where the maintenance vehicle D enters from the branching device rear end Y or Z, passes through the branching device, and then travels backward before passing over the detection receiving antenna 17 provided at the front end position of the branching device. Will be explained.
That is, when the maintenance vehicle D enters from the rear end direction Y or Z of the branching unit, passes through the branching unit, and moves backward before passing over the detection receiving antenna 17 installed at the front end position, maintenance is performed. The car D is temporarily stopped. When the reverse button 34 of the in-vehicle reception box 27 is pressed in this state, the right selection button 30 and the left selection button 31 of the in-vehicle reception box 27 simultaneously flash and emit light, and the alarm buzzer 32 sounds intermittently. This operation is the same as that when entering from the front end direction X of the branching device except that the confirmation button 34 is lit, and thereafter the same operation as that when entering from the front end direction X of the branching device is performed.
