本発明を実施するための最良の形態を説明する。
以下、本発明の鉄道車両用通信装置の実施例を説明する。はじめに、列車運行の最少編成(基本編成)時を例とし、本発明の基本概念を実施例1として図1〜図3により説明する。図2は、車両のシステム基本構成図である。
The best mode for carrying out the present invention will be described.
Embodiments of the railway vehicle communication device according to the present invention will be described below. First, the basic concept of the present invention will be described as Example 1 with reference to FIGS. FIG. 2 is a basic system configuration diagram of the vehicle.

各号車をまとめた車両群7を基本編成とする。基本編成は、車両を繋げる連結器9により接続され車両をまとめた構成になっている。各号車間の通信に本実施例の鉄道車両用通信装置が用いられ、車両内の制御装置との通信を行う。通信は、搬送波感知多重アクセス/衝突検出方式で行う。   A basic group is a vehicle group 7 in which the cars are grouped. The basic knitting has a configuration in which the vehicles are gathered by being connected by a coupler 9 that connects the vehicles. The railway vehicle communication device according to the present embodiment is used for communication between vehicles, and communicates with a control device in the vehicle. Communication is performed by a carrier sense multiple access / collision detection method.

図1は、本実施例の鉄道車両用通信装置のハード構成図である。鉄道車両用通信装置1は、構成制御部2とイーサネットを分岐するスイッチングハブ3と、伝送路6に接続されるスイッチングハブ3の前方向又は後方向の送受信の接続および切断ができる2つのスイッチ4より構成される。鉄道車両用通信装置1が車両制御装置5に接続されたハード構成にて車両の制御を行うシステムであり、制御データの通信を行う。この制御データ通信を行うにあたり、他の通信装置1の所在を管理する情報(構成情報)を各通信装置1で管理する必要がある。これらの構成情報を管理するにあたっては、各通信機器1が持つ自車両内の構成情報が必要であり、次の方法で収集・管理を行う。   FIG. 1 is a hardware configuration diagram of a railway vehicle communication device according to the present embodiment. The railway vehicle communication apparatus 1 includes a configuration control unit 2, a switching hub 3 that branches off the Ethernet, and two switches 4 that can connect and disconnect forward / backward transmission / reception of the switching hub 3 connected to the transmission path 6. Consists of. The railway vehicle communication device 1 is a system that controls a vehicle with a hardware configuration connected to the vehicle control device 5 and communicates control data. In performing this control data communication, it is necessary to manage information (configuration information) for managing the location of other communication devices 1 in each communication device 1. In order to manage these pieces of configuration information, configuration information in the own vehicle possessed by each communication device 1 is necessary and is collected and managed by the following method.

図3は、基本編成内構成図である。基本編成立上げ時、基本編成7−1内の先頭号車通信装置1の前方向側スイッチ4−11ならびに最終号車通信装置1の後方向側スイッチ4−16を切断した状態に設定しておく。基本編成7−1内において先頭号車か最終号車かの識別は各通信装置1および制御装置5で個別にもつアドレス設定スイッチ10の号車および車両数情報によって各通信装置1内の構成制御部2で認識することができ、スイッチ4の接続および切断を制御する。各通信装置1は、自車両構成状態を付加したネットワーク構成状態フレームを全号車の通信装置1に周期的に送信する。同時に各通信装置1は他号車からのネットワーク構成状態フレームを受信し、フレーム内の号車番号・アドレス情報等をもとに構成制御部2にて編成内構成状態テーブルを作成する。基本編成7内で構成状態テーブルを最終号車まで作成完了時、各通信装置1は、自車両制御装置5に構成状態通知フレームにて構成状態テーブルを通知する。   FIG. 3 is a configuration diagram in the basic organization. At the time of starting the basic train, the forward switch 4-11 of the first car communication device 1 and the rear switch 4-16 of the final car communication device 1 in the basic train 7-1 are set in a disconnected state. In the basic train 7-1, whether the first car or the last car is identified by the configuration control unit 2 in each communication device 1 based on the number and vehicle number information of the address setting switch 10 that the communication device 1 and the control device 5 individually have. It can be recognized and controls connection and disconnection of the switch 4. Each communication device 1 periodically transmits a network configuration state frame to which the own vehicle configuration state is added to the communication devices 1 of all cars. At the same time, each communication device 1 receives a network configuration status frame from another car, and creates a composition status table within the composition by the configuration control unit 2 based on the car number / address information in the frame. When the creation of the configuration state table up to the last car in the basic organization 7 is completed, each communication device 1 notifies the host vehicle control device 5 of the configuration state table in the configuration state notification frame.

このように、各通信装置1は独立に自己編成構成情報を構築・管理を行うことが可能であり、編成内においてマスタ通信装置は存在しない。   Thus, each communication device 1 can independently construct and manage self-organization configuration information, and there is no master communication device in the composition.

次に、車両群2編成時における構成管理情報構築の例について、本発明の実施例2として図3および図4を用いて説明する。自基本編成以外に編成が存在するかどうかの認識は、連結信号8が有るか否かによって連結部隣接の車両制御装置5にて判断する。他編成有りと認識した車両制御装置5は、自車両通信装置1に併合指令を行う。   Next, an example of construction of configuration management information at the time of formation of two vehicle groups will be described with reference to FIGS. 3 and 4 as a second embodiment of the present invention. Recognition of whether or not there is a knitting other than the own basic knitting is determined by the vehicle control device 5 adjacent to the connecting portion depending on whether or not the connecting signal 8 is present. The vehicle control device 5 that has recognized that there is another organization issues a merge command to the own vehicle communication device 1.

車両群2編成時における構成情報構築は、最初に各基本編成内から開始する。前述の方法により自基本編成内の構成情報構築終了後、車両制御装置5から上記併合指令を受信した先頭基本編成7−1の最終号車通信装置1は後方向側スイッチ4−16を、同様に最後尾編成7−2の先頭号車通信装置1は前方向側スイッチ4−21をそれぞれ接続状態にする。   The construction of construction information at the time of the formation of the vehicle group 2 starts first from within each basic formation. After the construction of the configuration information in the own basic train is completed by the above-described method, the last car communication device 1 of the leading basic train 7-1 that has received the merge command from the vehicle control device 5 sets the rear side switch 4-16 in the same manner. The first car communication device 1 of the last train 7-2 sets the forward switch 4-21 to the connected state.

これにより、各基本編成間にて伝送路6が接続され、編成間の通信が可能となり、相互に相手側から編成内ネットワーク構成状態フレームを送受信(交換)し、自己編成構成状態テーブルに隣接基本編成内の構成情報を追加していく。   As a result, the transmission line 6 is connected between the basic trains, communication between the trains becomes possible, and the network configuration status frame within the train is mutually exchanged (exchanged) from the partner side, and the adjacent basics in the self-organization configuration status table Add configuration information in the organization.

先頭基本編成7−1の最終号車通信装置1と最後尾編成7−2の先頭号車通信装置1は自編成内の全通信装置1に対して新構成状態フレームを送信する。自己編成構成状態テーブルを作成完了後、各通信装置1は自車両制御装置5に構成状態通知フレームにて構成状態テーブルを通知する。   The last car communication device 1 of the first basic train 7-1 and the first car communication device 1 of the last train 7-2 transmit the new configuration state frame to all the communication devices 1 in the own train. After completing the creation of the self-organization configuration state table, each communication device 1 notifies the host vehicle control device 5 of the configuration state table with a configuration state notification frame.

このようにして、2編成時においてもマスタ通信装置の存在無しで、車両全体の構成情報を構築・管理することが可能となる。   In this way, it is possible to construct and manage the configuration information of the entire vehicle without the presence of the master communication device even in the second train.

次に車両群2編成以上の複合編成時における構成管理情報構築の例を本発明の実施例3として図3および図5を用いて説明する。車両群2編成以上の複合編成での電源投入および同時併合時における構成情報構築では、中間位置の基本編成7−2または7−3が前・後方の隣接基本編成と同時に編成隣接側スイッチ4を接続状態にすると前後方向の編成のどちらから受信したかわからなくなるため、先頭基本編成7−1から構成情報構築を開始する。   Next, an example of construction of configuration management information at the time of composite formation of two or more vehicle groups will be described with reference to FIGS. 3 and 5 as Embodiment 3 of the present invention. When constructing the configuration information when turning on the power and simultaneously merging in the composite formation of two or more vehicle groups, the basic composition 7-2 or 7-3 at the intermediate position simultaneously activates the composition adjacent switch 4 at the same time as the front / rear adjacent basic composition. Since it becomes impossible to know from which of the knitting in the front-rear direction when it is in the connected state, construction of construction information is started from the head basic knitting 7-1.

尚、複数編成構成にて、各々の編成が先頭であるか中間であるか、または最後尾であるかは、連結信号8の有無と号車番号にて編成連結部に隣接する各車両制御装置5が認識し、自号車の通信装置1に通知する。また、車両群2編成以上の複合編成時における構成情報構築にあたっても、最初に各基本編成内から開始する。   In the multi-knitting configuration, each vehicle control device 5 adjacent to the knitting connecting portion 5 is determined by the presence / absence of the connecting signal 8 and the car number, whether each knitting is the first, middle or last. Is recognized and notified to the communication device 1 of the own car. Also, in constructing the configuration information at the time of composite knitting of two or more vehicle groups, first, it starts from within each basic knitting.

自編成内の構成情報構築終了後、車両制御装置5から併合開始を通知された中間基本編成7−2、7−3および最後尾基本編成7−4の先頭号車の通信装置1は前方向側スイッチ4−21、4−31、4−41を接続し、先頭基本編成7−1の最終号車の通信装置1のみ後方向側スイッチ4−16を接続する。   The communication device 1 of the first car of the intermediate basic formations 7-2 and 7-3 and the last basic formation 7-4 notified of the start of merging by the vehicle control device 5 after the construction of the configuration information in the self-organization is on the front side The switches 4-21, 4-31, and 4-41 are connected, and the rear switch 4-16 is connected only to the communication device 1 of the last car of the leading basic organization 7-1.

まず、先頭基本編成7−1と中間基本編成7−2の2編成間にて、先に実施例2にて説明した方法にて構成情報構築を開始する。先頭基本編成7−1と中間基本編成7−2間にて構成情報構築を完了したならば、中間基本編成7−2の最終号車の通信装置1のみ後方向側スイッチ4−26を接続して、更に次後隣接する中間基本編成7−3間にて構成情報構築を行う。以降、順に構成情報構築を行い、最後尾基本編成7−4まで構成状態テーブルを作成完了後、各通信装置1は自車両制御装置5に構成状態通知フレームにて構成状態テーブルを通知する。   First, construction of construction information is started between the first basic composition 7-1 and the intermediate basic composition 7-2 by the method described in the second embodiment. When the construction of the configuration information is completed between the leading basic organization 7-1 and the intermediate basic organization 7-2, only the communication device 1 of the last car of the intermediate basic organization 7-2 is connected to the rear side switch 4-26. Further, construction information is constructed between the adjacent intermediate basic formations 7-3. Thereafter, the configuration information is constructed in order, and after creating the configuration state table up to the last basic formation 7-4, each communication device 1 notifies the host vehicle control device 5 of the configuration state table in the configuration state notification frame.

このようにして、車両群2編成以上の複合編成時においてもマスタ通信装置の存在無しで、車両全体の構成情報を構築・管理することが可能である。   In this way, it is possible to construct and manage the configuration information of the entire vehicle without the presence of the master communication device even in the combined formation of two or more vehicle groups.

上記実施例により、車両内の全ての通信装置1は同一の構成情報を構築することができ、構成情報構築後も各通信装置1は全ての通信装置1に対して自己構成状態を周期的に送信することで、自車両内通信機器の障害または切り離し・新規接続等により自己構成状態に変更が発生しても、車両内の全ての通信装置1は当該構成状態変更情報を認知し、常に同一の構成情報を共有・管理することができる。   According to the above embodiment, all the communication devices 1 in the vehicle can construct the same configuration information, and each communication device 1 periodically sets its own configuration state to all the communication devices 1 even after the configuration information is constructed. By transmitting, even if a change occurs in the self-configuration state due to a failure or disconnection / new connection of the communication device in the vehicle, all the communication devices 1 in the vehicle recognize the configuration state change information and are always the same Configuration information can be shared and managed.

列車運行にあたっては、これまで説明してきた編成併合(接続)と同様に編成分割(切り離し)がある。編成を分割する場合も、編成併合時と同様に構成情報の再構築が必要になる。   In train operation, there is formation division (separation) in the same way as formation combination (connection) described so far. Even when the organization is divided, it is necessary to reconstruct the configuration information in the same manner as when the organization is merged.

車両群2編成時の分割による構成管理情報再構築の例を本発明の実施例4として図3および図6により説明する。編成分割の発生の認識は、連結信号8が有から無の変化によって連結部隣接の車両制御装置5にて判断する。分割発生を認識した車両制御装置5は自車両通信装置1に分割指令を行う。   An example of reconfiguration of configuration management information by division at the time of formation of two vehicle groups will be described with reference to FIGS. 3 and 6 as Embodiment 4 of the present invention. The recognition of the occurrence of the knitting division is determined by the vehicle control device 5 adjacent to the connecting portion when the connecting signal 8 changes from being present to not being present. The vehicle control device 5 that has recognized the occurrence of the division issues a division command to the host vehicle communication device 1.

車両制御装置5から分割指令を受信した先頭基本編成7−1の最終号車通信装置1は後方向側スイッチ4−16を、同様に最後尾基本編成7−2の先頭号車通信装置1は前方向側スイッチ4−21を切断状態にし、分割された編成の構成情報を自己編成構成状態テーブルから削除する。   The last car communication device 1 of the first basic train 7-1 that has received the split command from the vehicle control device 5 is the rear switch 4-16, and similarly, the first car communication device 1 of the last basic train 7-2 is the forward drive. The side switch 4-21 is set to the disconnected state, and the divided composition configuration information is deleted from the self-organization configuration state table.

基本編成7−1の最終号車通信装置1と基本編成7−2の先頭号車通信装置1は自編成内の全通信装置1に対して再構成後の新構成状態フレームを送信する。
自己編成構成状態テーブルを作成完了後、各通信装置1は自車両制御装置5に構成状態通知フレームにて構成状態テーブルを通知する。このようにして、編成分割時においてもマスタ通信装置の存在無しで、車両全体の構成情報を構築・管理することが可能である。
The last car communication device 1 of the basic train 7-1 and the first car communication device 1 of the basic train 7-2 transmit the reconfigured new configuration state frame to all the communication devices 1 in the self train.
After completing the creation of the self-organization configuration state table, each communication device 1 notifies the host vehicle control device 5 of the configuration state table using a configuration state notification frame. In this way, it is possible to construct and manage the configuration information of the entire vehicle without the presence of the master communication device even at the time of knitting division.

本発明におけるシステム構成を2重化することで、より高信頼な車両ネットワークを構築することができる。システム2重化の例を、本発明の実施例5として図7により説明する。   By duplicating the system configuration in the present invention, a more reliable vehicle network can be constructed. An example of system duplication will be described with reference to FIG. 7 as Embodiment 5 of the present invention.

図7に示すように、各車両内のコンポーネントは伝送路も含め全て2重化で構成し、1系伝送路6−1および2系伝送路6−2は、各号車内通信装置1間の伝送路6−3で接続される。構成情報構築は1系、2系それぞれ独立に行うとともに、各号車内通信装置1間の伝送路6−3を使用して自系構成情報を他系にも送信することで、各系にて同一の構成情報を共有・管理することができる。   As shown in FIG. 7, all the components in each vehicle, including the transmission path, are configured in a duplex manner, and the 1-system transmission path 6-1 and the 2-system transmission path 6-2 are connected between the intra-vehicle communication apparatuses 1. They are connected by a transmission line 6-3. Configuration information construction is performed independently for each of the first and second systems, and by transmitting the own system configuration information to other systems using the transmission path 6-3 between each in-car communication device 1, each system The same configuration information can be shared and managed.

また、自系伝送路にて伝送路切断や通信装置故障等の障害が発生し通信経路が途絶えても、各号車内通信装置1間の伝送路6−3を迂回することによって通信を継続することができる。   Further, even if a failure such as a transmission line disconnection or a communication device failure occurs in the own transmission line and the communication route is interrupted, communication is continued by bypassing the transmission line 6-3 between the intra-vehicle communication devices 1 be able to.

更に、伝送路6−1(または6−2)に対して通信装置1のフレーム出し続け故障の障害に対しても、次号車の通信装置1にてフレーム異常受信を検出し、障害側伝送路のスイッチ4を切断して該当障害部の伝送路を切離すことで、障害部以降の伝送路6への障害波及を回避することができる。   Furthermore, even if the failure of the communication device 1 continues to be out of the frame with respect to the transmission line 6-1 (or 6-2), the communication device 1 of the next car detects the abnormal frame reception, and the failure side transmission line By disconnecting the switch 4 and disconnecting the transmission path of the faulty part, it is possible to avoid the faulty propagation to the transmission path 6 after the faulty part.

このように自系および他系の通信装置1間はスイッチングハブ3にて1:1通信で構成されており、また伝送路6の接続・切断をコントロールするスイッチ4を持つことで、伝送路障害が全車両内に波及することを回避でき、車両内の通信停止を無くし信頼性を向上することができる。   In this way, the communication system 1 between the own system and the other system is configured by 1: 1 communication with the switching hub 3 and also has a switch 4 for controlling connection / disconnection of the transmission path 6, thereby causing a transmission path failure. Can be prevented from spreading in the entire vehicle, communication stoppage in the vehicle is eliminated, and reliability can be improved.
