Description

本発明は，所定の軌道上を走行する移動体、例えば鉄道、モノレールや新交通システムの信号保安システムにおける移動体間の無線通信に関するものである。   The present invention relates to wireless communication between moving bodies in a signal safety system of a moving body that travels on a predetermined track, such as a railway, a monorail, or a new traffic system.

近年、鉄道、モノレールにおける無線通信を用いた移動閉そく方式の信号保安システムにおいては，軌道沿線に地上無線機およびアンテナを配置し、列車に地上無線機と通信を行うための車上アンテナおよび車上無線機を配置し、車上装置は自列車の位置情報を前記無線通信を介して地上装置に送信し、地上装置は、受信した列車位置情報に基づき各列車の位置を管理し、各列車に対して、前記無線通信を介して、停止限界あるいは速度情報を含む制御情報を送信することで、車上装置は制限速度パターンに基づき、列車の速度制御を行う。   2. Description of the Related Art In recent years, in a mobile block-type signal security system using radio communication on railways and monorails, an on-board antenna and an on-board antenna for communicating with a terrestrial radio on a train by arranging a terrestrial radio and an antenna along the track. The radio equipment is arranged, the on-board device transmits the position information of the own train to the ground device via the wireless communication, and the ground device manages the position of each train based on the received train position information. On the other hand, by transmitting control information including stop limit or speed information via the wireless communication, the on-board device performs train speed control based on the speed limit pattern.

通常、車上無線機およびアンテナは、列車の先頭と後尾に配置され、一方の無線機が故障あるいは外乱の影響により、通信できない場合、他方で通信を行う冗長性が取られる。   Usually, onboard radios and antennas are arranged at the head and tail of a train, and when one radio cannot communicate due to a failure or disturbance, redundancy is provided for communication on the other.

一方、２つの列車が併合した場合、併合車と被併合車の連結部分に位置する双方の車上アンテナは、お互いの正面に位置する列車の車体が障害物となり、地上装置との無線通信に干渉するため、無線アンテナは正面の列車が干渉しないように列車の上部などに突き出した形で設置される場合もある。   On the other hand, when two trains are merged, both on-board antennas located at the connecting part of the merged vehicle and the merged vehicle are obstructed by the body of the train located in front of each other, for wireless communication with the ground equipment In order to interfere, the radio antenna may be installed in a protruding manner on the upper part of the train so that the front train does not interfere.

併合時の列車制御に関して、例えば特許文献１に、併合車との通信を停止して、被併合車のみと通信するような方式が提案されている。しかし、このような方式は、地上装置が併合車の列車ＩＤを削除したり、連結された列車が分割した後、併合車の列車ＩＤを復活したり、および一連の列車運行の管理を変更しなければならない。また、被併合車のみと通信することになり冗長性が確保されていないため、被併合車の車上制御装置および車上無線局、車上アンテナは、装置の故障や外乱により無線通信で不能となった場合には、列車制御を継続できない。   Regarding train control at the time of merging, for example, Patent Document 1 proposes a method in which communication with the merged vehicle is stopped and communication with only the merged vehicle is performed. However, in such a system, the ground device deletes the train ID of the merged vehicle, the train ID of the merged vehicle is restored after the connected train is divided, and the management of a series of train operations is changed. There must be. In addition, because it communicates only with the merged vehicle and redundancy is not ensured, the onboard control device, onboard radio station, and onboard antenna of the merged vehicle cannot be wirelessly communicated due to equipment failure or disturbance If it becomes, train control cannot be continued.

併合時の列車制御を行う場合において、併合車、被併合車のそれぞれの車上制御装置で速度制御を行う場合、各列車の位置検知の誤差、あるいはブレーキ性能の差に伴う制限速度パターンの相違に伴い、ブレーキタイミングのずれが発生するなどの課題がある。   When performing train control at the time of merging, if speed control is performed by the on-board control device of each merged vehicle and merged vehicle, the difference in speed limit pattern due to errors in position detection of each train or differences in brake performance As a result, there is a problem that a shift in brake timing occurs.

そのため、併合車、被併合車の車上制御装置間で制御情報の送受信等の通信を行い、共通の制御を実施する必要があるが、その際、車上制御装置間で制御情報の送受信を行う必要がある。制御情報の送受信においては、列車の連結器部分に伝送ケーブルを設け、併合車、被併合車間で接続するものが一般的である。   Therefore, it is necessary to perform communication such as transmission / reception of control information between the on-board control devices of the merged vehicle and the merged vehicle, and to perform common control. There is a need to do. In transmission / reception of control information, it is common to provide a transmission cable at a train coupler and connect between a merged vehicle and a merged vehicle.

しかし、伝送ケーブルによる接続においては、連結器部分に伝送ケーブルの設置が必要となり、機構が複雑となる、また、列車併合時に人によるケーブルの接続、および確認が必要になり、列車併合に時間を要するなどの課題がある。   However, when connecting with a transmission cable, it is necessary to install a transmission cable at the coupler part, which complicates the mechanism. In addition, it is necessary to connect and check the cable when the trains are merged. There is a problem such as need.

この発明の目的は，併合時に、併合車と被併合車の間で伝送ケーブルを接続する作業に掛かる時間を省くまたは減少さえることにより設備コストの低減および運用性の向上を可能とする列車制御システムを提供することである。   An object of the present invention is a train control system capable of reducing equipment costs and improving operability by omitting or even reducing the time required to connect transmission cables between a merged vehicle and a merged vehicle at the time of merging. Is to provide.

上記課題を解決するため，この発明による列車制御システムにおいては、通常の１列車での走行時に、地上装置との通信に使用する列車の先頭および後尾の列車アンテナおよび車上無線機の一方を、２列車が併合した場合、併合車と被併合車の車上制御装置間の通信に使用することを特徴とする。   In order to solve the above-described problem, in the train control system according to the present invention, when traveling with a normal one train, one of the front and rear train antennas and the onboard radio used for communication with the ground device is used. When two trains merge, it is used for communication between the on-board control devices of the merged vehicle and the merged vehicle.

本発明による列車制御システムによれば，連結器部分の伝送ケーブル等の設備を増加することなく，併合時の併合車と被併合車の車上制御装置間のデータ通信を実現することで設備コストが低減でき，人によるケーブルの接続および確認作業に掛かる時間を減少させることで運用性に優れた列車制御システムを提供することができる。   According to the train control system of the present invention, it is possible to reduce the equipment cost by realizing data communication between the merged vehicle at the time of merging and the on-board controller of the merged vehicle without increasing the number of facilities such as the transmission cable of the coupler part. It is possible to provide a train control system with excellent operability by reducing the time required for cable connection and confirmation work by humans.

以下，添付した図面を参照して，この発明による列車制御システムの実施形態を説明する。   Hereinafter, an embodiment of a train control system according to the present invention will be described with reference to the accompanying drawings.

図１は，本発明である列車制御システムの構成図である。   FIG. 1 is a configuration diagram of a train control system according to the present invention.

地上制御装置２０１は、列車００１を含む制御範囲内の複数の列車から地上アンテナ２２１〜２２３及び地上無線局２１１〜２１３を介して受信した位置情報を管理し、その位置情報および信号機、転てつ器などの状態に基づき、各列車への制御情報を編集する装置である。地上制御装置２０１は、編集した制御情報を沿線に配置された地上無線局２１１〜２１３に伝送し、地上無線局２１１〜２１３は地上アンテナ２２１〜２２３を介して、制御情報を各列車００１に送信する。制御情報は、車上に配置された車上アンテナ０３１、０３２、車上無線局０２１、０２２を介して、車上制御装置０１１、０１２に伝送される。   The ground control device 201 manages position information received from a plurality of trains within the control range including the train 001 via the ground antennas 221 to 223 and the ground radio stations 211 to 213, and the position information, traffic lights, It is a device that edits control information for each train based on the state of the vessel. The ground control device 201 transmits the edited control information to the ground radio stations 211 to 213 arranged along the line, and the ground radio stations 211 to 213 transmit the control information to each train 001 via the ground antennas 221 to 223. To do. The control information is transmitted to the onboard control devices 011 and 012 via the onboard antennas 031 and 032 and the onboard radio stations 021 and 022 arranged on the vehicle.

一方、車上制御装置０１１、０１２は、自列車の走行位置を算出し、当該走行位置と地上制御装置２０１から受信した制御情報に基づき列車の速度・停止制御を行う装置である。車上制御装置０１１、０１２は、自列車００１の走行位置を位置情報として編集し、編集した位置情報を車上無線局０２１、０２２に伝送する。車上無線局０２１、０２２は車上アンテナ０３１、０３２を介して、位置情報を地上装置に送信する。位置情報は、沿線上に配置された地上アンテナ２２１〜２２３、地上無線局２１１〜２１３を介して、地上制御装置２０１に伝送される。   On the other hand, the on-board control devices 011 and 012 are devices that calculate the travel position of the own train and perform train speed / stop control based on the travel position and control information received from the ground control device 201. The on-board controllers 011 and 012 edit the travel position of the own train 001 as position information, and transmit the edited position information to the on-board radio stations 021 and 022. The on-board radio stations 021 and 022 transmit the position information to the ground device via the on-board antennas 031 and 032. The position information is transmitted to the ground control device 201 via the ground antennas 221 to 223 and the ground radio stations 211 to 213 arranged on the railway line.

車上制御装置０１１、０１２および車上無線局０２１、０２２、車上アンテナ０３１、０３２は、装置の故障や外乱により無線通信で不能となった場合においても制御を継続するため、２重系の冗長構成をとる。車上アンテナ０３１、０３２および車上無線局０２１、０２２は、列車の先頭および後尾に配置され、１列車での運行時は、各先頭の車上アンテナ０３１と車上無線局０２１および後尾の車上アンテナ０３２と車上無線局０２２で、地上装置との無線通信を行う。   The on-board control devices 011 and 012, the on-board radio stations 021 and 022, and the on-board antennas 031 and 032 continue to control even when wireless communication is disabled due to a device failure or disturbance. Take a redundant configuration. The on-board antennas 031 and 032 and the on-board radio stations 021 and 022 are arranged at the head and rear of the train, and when operating on one train, each on-board antenna 031, the on-board radio station 021 and the rear car The upper antenna 032 and the on-vehicle wireless station 022 perform wireless communication with the ground device.

図２は、２つの列車が併合した場合の通信状態を示す図である。２つの列車００１、１０１が併合した場合、車上制御装置１１１、０１２はモード情報を取得することにより、列車００１の後尾側と列車１０１の先頭側が併合したことを検知する。そして、併合車１０１の先頭車上無線局１２１および被併合車００１の後尾車上無線局０２２は、併合したことを示すモード情報を車上制御装置１１１、０１２から受信することで、無線通信チャンネル(周波数)を地上装置との通信用の無線通信チャンネルとは異なる値である列車間通信用の無線通信チャンネル(周波数)切り換える。これにより、併合車１０１の車上制御装置１１１と被併合車００１の車上制御装置間０１２での無線通信を可能とする。   FIG. 2 is a diagram illustrating a communication state when two trains are merged. When the two trains 001 and 101 are merged, the on-board control devices 111 and 012 detect that the rear side of the train 001 and the top side of the train 101 are merged by acquiring the mode information. Then, the top on-board radio station 121 of the merged vehicle 101 and the rear on-vehicle radio station 022 of the merged vehicle 001 receive mode information indicating that they are merged from the on-board control devices 111 and 012, so that the radio communication channel (Frequency) is switched to a radio communication channel (frequency) for inter-train communication, which is a value different from the radio communication channel for communication with the ground device. This enables wireless communication between the on-board control device 111 of the merged vehicle 101 and the on-board control device 012 of the merged vehicle 001.

また、併合車１０１の後尾の車上無線局１２２および被併合車００１の先頭の車上無線局０２１は、地上装置との無線通信を継続する。   The rear onboard radio station 122 of the merged vehicle 101 and the first onboard radio station 021 of the merged vehicle 001 continue radio communication with the ground device.

なお、モード情報は、地上装置からの制御情報に含まれる場合、あるいは運転台のスイッチ操作により提供される場合、あるいは車上制御装置で併合状態を自動検知することにより生成される場合が想定される。   It is assumed that the mode information is included in the control information from the ground device, provided by switch operation of the driver's cab, or generated by automatically detecting the merged state with the on-board control device. The

併合車１０１、被併合車００１の車上制御装置１１１、１１２、０１１、０１２は、列車制御に必要となる列車識別情報(列車長、列車ＩＤ、ブレーキ特性など)を、併合車１０１の先頭の車上無線局１２１と被併合車００１の後尾の車上無線局０２２を介した車上制御装置１１１、０１２間の無線通信により交換することで、併合車１０１及び被併合車００１を１つの列車としてブレーキや加速などの駆動制御を実施する。また、併合車１０１、被併合車００１の車上制御装置１１１、１１２、０１１、０１２は、併合車１０１の後尾の車上無線局１２２および被併合車００１の先頭の車上無線局０２１が地上制御装置から受信した制御情報を、列車内の各車上制御装置の間で有線通信を介して交換し、さらに併合車１０１の車上制御装置１１１と被併合車００１の車上制御装置０１２の間の無線通信を介して交換することで、各車上制御装置１１１、１１２、０１１、０１２は、共通の制御情報により列車制御を行うことが可能となる。   The on-board control devices 111, 112, 011 and 012 of the merged vehicle 101 and the merged vehicle 001 provide train identification information (train length, train ID, brake characteristics, etc.) necessary for train control at the head of the merged vehicle 101. By exchanging by radio communication between the on-board control devices 111 and 012 via the on-board radio station 121 and the on-board radio station 022 at the rear of the merged vehicle 001, the merged vehicle 101 and the merged vehicle 001 are converted into one train. As such, drive control such as braking and acceleration is implemented. Further, the onboard control devices 111, 112, 011 and 012 of the merged vehicle 101 and the merged vehicle 001 are connected to the rear vehicle radio station 122 of the merged vehicle 101 and the onboard radio station 021 of the merged vehicle 001 is the ground. The control information received from the control device is exchanged between the on-board control devices in the train via wired communication. Further, the on-board control device 111 of the merged vehicle 101 and the on-board control device 012 of the merged vehicle 001 By exchanging via wireless communication between them, the on-board control devices 111, 112, 011 and 012 can perform train control using common control information.

このように併合した場合に、被併合車００１の先頭の車上無線局０２１と、併合車１０１の後尾の車上無線局１２２とが、地上装置との無線通信を行うことで、無線通信の冗長性を損なうこととはない。また、併合車１０１と被併合車００１の連結部に面する併合車１０１の先頭の車上無線局１２１と被併合車００１の後尾の車上無線局０２２は、地上装置との無線通信を行わないため、車上アンテナ１３１、０３２の正面に列車が存在しても無線通信が干渉されることは無く、車上アンテナ１３１、０３２を列車上部などに配置する必要はない。   In this way, when the onboard radio station 021 at the head of the merged vehicle 001 and the onboard radio station 122 at the rear of the merged vehicle 101 perform radio communication with the ground device, There is no loss of redundancy. The onboard radio station 121 at the head of the merged vehicle 101 facing the connecting portion of the merged vehicle 101 and the merged vehicle 001 and the onboard radio station 022 at the rear of the merged vehicle 001 perform wireless communication with the ground device. Therefore, even if a train is present in front of the on-board antennas 131 and 032, wireless communication is not interfered, and the on-board antennas 131 and 032 need not be arranged on the upper part of the train.

図３は，本列車制御システムを適用した場合の各車上装置の動作モードの例を示す。   FIG. 3 shows an example of the operation mode of each on-board device when this train control system is applied.

２つの列車が併合した場合、併合車１０１の先頭の車上制御装置１１１および被併合車００１の後尾の車上制御装置０１２は、併合モードに遷移し、車上制御装置１１１、０１２間の無線通信を制御する。また、進行方向前方の被併合車００１の先頭の車上制御装置０１１を主系、併合車１０１の後尾の車上制御装置１１２を従系とする。   When the two trains are merged, the onboard control device 111 at the head of the merged vehicle 101 and the onboard control device 012 at the rear of the merged vehicle 001 shift to the merge mode, and the radio between the onboard control devices 111 and 012 Control communication. Further, the head onboard control device 011 of the merged vehicle 001 ahead in the traveling direction is the main system, and the rear onboard control device 112 of the merged vehicle 101 is the subordinate system.

被併合車００１の先頭の車上制御装置０１１で保有している車両識別情報と、併合車１０１の後尾の車上制御装置１１２で保有している制御モード（主系モード、または従系モード、または併合モード）や故障情報を含む制御装置管理情報を、被併合車００１の車両内の各車両制御装置０１１，０１２間の通信と、併合車１０１の車両内の各車両制御装置１１１、１１２間の通信と、併合車１０１の車上制御装置１１１と被併合車００１の車上制御装置０１２の間の無線通信を介して交換することで、車上制御装置の冗長化構成を確保する。通常は、主系である被併合車００１の先頭の車上制御装置０１１で列車制御を行い、被併合車００１の先頭の車上制御装置０１１に故障が発生したことを意図する故障情報を後尾の車上制御装置１１２が受信した場合は、併合車１０１の後尾の車上制御装置１１２が主系に切換り、列車制御を継続する。   The vehicle identification information held by the head onboard control device 011 of the merged vehicle 001 and the control mode (main mode or subordinate mode) held by the rear onboard control device 112 of the merged vehicle 101 Or the control device management information including failure information) between the vehicle control devices 011 and 012 in the vehicle of the merged vehicle 001 and between the vehicle control devices 111 and 112 in the vehicle of the merged vehicle 101 Are exchanged via wireless communication between the on-board control device 111 of the merged vehicle 101 and the on-board control device 012 of the merged vehicle 001, thereby ensuring a redundant configuration of the on-board control device. Normally, train control is performed by the head onboard control device 011 of the merged vehicle 001 which is the main system, and failure information intended to indicate that a failure has occurred in the head onboard control device 011 of the merged vehicle 001 is added to the tail. Is received by the on-board control device 112, the rear on-board control device 112 of the merged vehicle 101 switches to the main system and train control is continued.

図４は，地上無線局と車上無線局の間の無線通信シーケンスの例を示す。また、図５は、車上無線局の間の無線通信シーケンスの例を示している。図４に示す地上無線局および車上無線局間の無線通信シーケンスにおいては、地上無線局からの周期的なポーリングに対して、車上無線局はアンサーを返信する。   FIG. 4 shows an example of a radio communication sequence between the ground radio station and the on-board radio station. FIG. 5 shows an example of a radio communication sequence between on-board radio stations. In the radio communication sequence between the terrestrial radio station and the on-board radio station shown in FIG. 4, the on-board radio station returns an answer to the periodic polling from the terrestrial radio station.

本無線通信シーケンスの例示においては、図５に示す併合時の車上制御装置間の無線通信を行う各列車の車上無線局において、一方の車上無線局が地上無線局モードとなり、周期的なポーリングを行うことで、他方の車上無線局はアンサーを返信する。   In the example of this wireless communication sequence, in the on-board radio station of each train that performs radio communication between the on-board control devices shown in FIG. The other on-board radio station returns an answer by performing the polling.

これにより、地上無線局との通信用の通信チャンネルから車上無線局同士の通信用の通信チャンネルへ無線通信チャンネル(周波数)を切り換えるだけで、一方の車上無線局は、地上無線局と同様の通信シーケンスで処理を行い、他方の車上無線局は通信シーケンスの変更を無くすことで無線通信処理の共通化を図ることが可能となる。   As a result, the on-board radio station is the same as the terrestrial radio station just by switching the radio communication channel (frequency) from the communication channel for communication with the terrestrial radio station to the communication channel for communication between the on-board radio stations. The other on-board radio station can eliminate the change of the communication sequence and can share the radio communication process.

本実施例では、２つの列車の先頭と後尾にそれぞれ車上アンテナを備えた列車が互いに連結する例を示したが、本発明は、列車の先頭と後尾に車上アンテナが配置されている列車に限らず、２つ以上の車上アンテナと車上無線局を搭載している列車であれば適用可能である。つまり、２つの列車が併合した場合に、列車内の２つ以上の車上アンテナの内、一方で地上無線局との通信を行い、他方で連結した他列車の車上無線局との通信を行うことにより、車両併合時に車両間を有線の伝送ケーブルで接続するという作業を実施する必要がなくなるという本発明の効果を達成できる。   In the present embodiment, an example is shown in which trains having on-board antennas are connected to each other at the head and tail of two trains, but the present invention is a train in which on-board antennas are arranged at the head and tail of the train. The present invention is not limited to this, and is applicable to any train that has two or more on-board antennas and on-board radio stations. That is, when two trains merge, one of the two or more on-board antennas in the train communicates with the ground radio station on one side, and communicates with the on-board radio station of the other train connected on the other side. By doing so, it is possible to achieve the effect of the present invention that it is not necessary to perform an operation of connecting the vehicles with a wired transmission cable when the vehicles are merged.

また、本発明の目的は、必ずしも併合時のケーブル接続作業を完全に無くすことではなく、列車間で複数のケーブルを接続する必要がある場合などに、少なくとも一部の情報を車両間で無線通信することで、併合時のケーブル接続作業を軽減することも含むものである。   In addition, the object of the present invention is not necessarily to completely eliminate cable connection work at the time of merging, but when it is necessary to connect a plurality of cables between trains, at least a part of information is wirelessly communicated between vehicles. This also includes reducing the cable connection work at the time of merging.
