Description

この発明は、軌道回路を使用しないで無線を利用した列車制御システムで列車の在線情報を確実に管理する列車在線情報管理方法に関するものである。   The present invention relates to a train track information management method for reliably managing train track information in a train control system using radio without using a track circuit.

軌道回路を使用しないで無線を利用した列車制御システムが特許文献１や特許文献２及び特許文献３等に開示されている。特許文献１に示された列車接近検知装置は、列車からの送信データを伝送する漏洩同軸ケーブルを踏切の列車進入側のレールに沿って敷設し、データ伝送部で漏洩同軸ケーブルを介して列車からの送信データを受信すると、列車が接近したことを検知している。   A train control system using radio without using a track circuit is disclosed in Patent Document 1, Patent Document 2, Patent Document 3, and the like. In the train approach detection device disclosed in Patent Document 1, a leaky coaxial cable that transmits transmission data from a train is laid along a rail on the train approach side of a railroad crossing, and the data transmission unit is connected to the train via the leaky coaxial cable. When the transmission data is received, it is detected that the train is approaching.

特許文献２に示された信号保安システムは、基地局と列車に設けられたアンテナを利用して地上と列車間で無線により情報を伝送する常用保安用の情報伝送システムと、特定位置に設けた地上通信子と列車に搭載された車上通信子による代用保安用の情報伝送システムとを併設し、無線による情報伝送システムが故障した場合、代用保安用の情報伝送システムに切り替えるようにしている。   The signal security system disclosed in Patent Document 2 is provided at a specific position with an information transmission system for regular security that transmits information between the ground and the train wirelessly using an antenna provided on the base station and the train. An information transmission system for substitute security using an on-board communicator and an on-board communicator mounted on a train is provided side by side, and when a wireless information transmission system breaks down, it is switched to the information transmission system for substitute security.

特許文献３に示された在線列車情報管理方法は、各列車検知装置には、それぞれ複数の閉そく区間の境界に設置された質問器が接続され、各質問器とレールを挟んで設けた地上応答器又は車上応答器からの応答信号を取り込んで前方の閉そく区間への列車進入を検知し、後方の閉そく区間からの列車進出を検知して在線列車情報を作成する。この各列車検知装置は作成した在線列車情報を他の列車検知装置に通信可能なようにネットワークを介して接続され、各列車検知装置間で在線列車情報を送受信するようにしている。そしてある列車検知装置が故障した場合、故障が復旧して再立上げした時に、その列車検知装置が管理する複数の閉そく区間の在線列車情報を他の列車検知装置から受信して在線列車情報を再設定して、無線を利用した列車検知装置が故障した場合の在線列車情報の再設定を自動的に行うようにしている。
特開平６−２５５４９２号公報 特開２００５−１７８６６７号公報 特開２００２−２５５０３３号公報 The on-line train information management method shown in Patent Document 3 is such that each train detection device is connected to an interrogator installed at the boundary of a plurality of closed sections, and a ground response is provided with each interrogator sandwiched between rails. The train signal from the vehicle or on-board responder is taken in, the train approach to the front block section is detected, the train advance from the rear block section is detected, and the in-line train information is created. Each train detection device is connected via a network so that the generated train information can be communicated to other train detection devices, and the train information is transmitted and received between the train detection devices. And when a certain train detection device breaks down, when the failure is recovered and re-started up, the train detection device manages the in-line train information from other train detection devices and receives the train-in-train information from other train detection devices. Re-setting is performed so that in-line train information is automatically reset when a train detection device that uses wireless communication fails.

無線を利用した列車制御システムで故障が生じた場合に対応するため、特許文献２に示すように、常用保安用と代用保安用の情報伝送システムとを併設すると、代用保安用の地上通信子を各閉そく区間に設けるとともに車上通信子を設ける必要があり、情報伝送システムが複雑化する。   In order to cope with a failure in a train control system using radio, as shown in Patent Document 2, when an information transmission system for regular security and alternate security is installed, a ground communicator for substitute security is provided. It is necessary to provide an on-board communicator in each block section, and the information transmission system becomes complicated.

また、特許文献３に示すように、１つの列車検知装置で複数の閉そく区間の列車在線状態を管理していると、ある閉そく区間に列車が在線しているときに、その列車検知装置に故障が生じ、その故障が復旧して再立上げした時に、列車が前方の閉そく区間に移動している場合、他の列車検知装置から在線列車情報を受信して再設定しても実際の列車の在線状態が不明となってしまう。   In addition, as shown in Patent Document 3, if a train detection line manages the train line status of a plurality of blocked sections with a single train detection device, the train detection apparatus may fail when the train is on a certain block section. If the train is moving to the front closed section when the failure is recovered and restarted, even if the train information is received and reset from other train detectors, the actual train The standing state becomes unknown.

この発明は、このような短所を改善し、無線を利用した列車制御システムで部分的な装置故障や停電が生じても各閉そく区間における列車の在線情報を確実保持することができる列車在線情報管理方法を提供することを目的とするものである。   The present invention improves such disadvantages, and train location information management that can reliably maintain train location information in each block section even if a partial equipment failure or power failure occurs in a radio train control system It is intended to provide a method.

この発明の列車在線情報管理方法は、無線を利用した列車制御システムの列車在線情報管理方法であって、列車に搭載した車上装置から送信される絶対位置情報に基づいて列車在線情報を作成して列車を制御する主系と従系のＡＴＣ装置を各閉そく区間に有し、各閉そく区間の主系のＡＴＣ装置と従系のＡＴＣ装置はそれぞれ第１の入出力チャネル（ｃｈ１）と第２の入出力チャネル（ｃｈ２）を有し、主系のＡＴＣ装置の第1の入出力チャネル（ｃｈ１）は伝送路を介して自閉そく区間の従系のＡＴＣ装置の第１の入出力チャネル（ｃｈ１）と列車進行方向に対して後方に隣接する閉そく区間に設けた主系と従系のＡＴＣ装置の第２の入出力チャネル（ｃｈ２）と情報を送受信し、主系のＡＴＣ装置の第２の入出力チャネル（ｃｈ２）は第１の入出力チャネル（ｃｈ１）が接続された伝送路とは異なる伝送路を介して自閉そく区間の従系のＡＴＣ装置の第２の入出力チャネル（ｃｈ２）と列車進行方向に対して前方に隣接する閉そく区間に設けた主系と従系のＡＴＣ装置の第１の入出力チャネル（ｃｈ１）と情報を送受信し、各閉そく区間の主系のＡＴＣ装置で作成した列車の在線の有無を含む情報を自閉そく区間の従系のＡＴＣ装置と隣接する閉そく区間の主系と従系のＡＴＣ装置に伝送して保持させることを特徴とする。 The train track information management method according to the present invention is a train track information management method for a train control system using radio, and creates train track information based on absolute position information transmitted from an onboard device mounted on a train. Main train and slave ATC devices for controlling the train in each block section, and the master ATC device and the slave ATC device in each block section are respectively the first input / output channel (ch1) and the second The first input / output channel (ch1) of the master ATC device is the first input / output channel (ch1) of the slave ATC device in the self-closing section via the transmission line. ) And the second input / output channel (ch2) of the main system and the subordinate ATC device provided in the block section adjacent to the rear in the train traveling direction, and the second of the main system ATC device Input / output channel (ch2) is first Adjacent to the second input / output channel (ch2) of the slave ATC device in the self-closing section via a transmission line different from the transmission line to which the input / output channel (ch1) is connected. Information including the presence / absence of the presence of a train on the primary ATC device of each block section that is transmitted / received to / from the first input / output channel (ch1) of the main system and the slave ATC device provided in the block section Is transmitted to and held by the slave ATC device in the self-closed section and the master and slave ATC devices in the adjacent closed section.

この発明の列車在線情報管理方法は、各閉そく区間の主系のＡＴＣ装置で作成した列車の在線の有無を含む情報を自閉そく区間の従系のＡＴＣ装置と隣接する閉そく区間の主系と従系のＡＴＣ装置に伝送して保持させることにより、列車の在線を検出したＡＴＣ装置が停止しても列車在線情報を確実に保持することができる。   The train tracking information management method according to the present invention provides information including the presence / absence of a train on the train created by the master ATC device in each block section, and the master system and the slave in the block section adjacent to the slave ATC device in the self block section. By transmitting to the ATC device of the system and holding it, even if the ATC device that detects the train line stops, the train line information can be reliably held.

また、各閉そく区間にそれぞれ主系と従系のＡＴＣ装置を設けたから、主系と従系のＡＴＣ装置を独立した場所に設置することができ、主系のＡＴＣ装置がダウンしても従系のＡＴＣ装置で在線状態を保持して列車の走行位置を追跡できるから、列車を安全に運行することができる。   In addition, since the main system and the subordinate ATC apparatus are provided in each block section, the main system and the subordinate ATC apparatus can be installed in independent locations, and the subordinate system even if the main ATC apparatus goes down. Since the ATC device can maintain the on-line state and track the traveling position of the train, the train can be operated safely.

さらに、各ＡＴＣ装置に情報を伝送する２系統の入出力チャネルを設けることにより、情報伝送のための同期を容易に取ることができる。   Furthermore, by providing two input / output channels for transmitting information to each ATC device, synchronization for information transmission can be easily achieved.

図１はこの発明の列車制御システムの構成を示すブロック図である。図に示すように、地上装置は、列車１が走行する閉そく区間ＡＴ〜ＣＴ毎に主系のＡＴＣ装置２ａ〜２ｃと従系のＡＴＣ装置３ａ〜３ｃとが設けられ、主系のＡＴＣ装置２ａ〜２ｃと従系のＡＴＣ装置３ａ〜３ｃはそれぞれ閉そく区間ＡＴ〜ＣＴ毎に設けられた連動装置４ａ〜４ｃに接続されている。主系のＡＴＣ装置２ａ〜２ｃと従系のＡＴＣ装置３ａ〜３ｃは、それぞれ２組の入出力チャネルｃｈ１，ｃｈ２を有し、そして同一閉そく区間、例えば閉そく区間ＢＴに設けた主系のＡＴＣ装置２ｂと従系のＡＴＣ装置３ｂの入出力チャネルｃｈ１は列車１の進行方向に対して後方の閉そく区間ＡＴに設けた主系のＡＴＣ装置２ａと従系のＡＴＣ装置３ａの入出力チャネルｃｈ２に例えば光ケーブル等の伝送路５ｂに接続されている。   FIG. 1 is a block diagram showing the configuration of the train control system of the present invention. As shown in the figure, the ground device is provided with main ATC devices 2a to 2c and subordinate ATC devices 3a to 3c for each block section AT to CT where the train 1 travels, and the main ATC device 2a. To 2c and subordinate ATC devices 3a to 3c are connected to interlocking devices 4a to 4c provided for each of the closed sections AT to CT, respectively. The main ATC devices 2a to 2c and the subordinate ATC devices 3a to 3c each have two sets of input / output channels ch1 and ch2, and the main ATC devices provided in the same closed section, for example, the closed section BT. The input / output channel ch1 of 2b and the slave ATC device 3b is connected to the input / output channel ch2 of the master ATC device 2a and the slave ATC device 3a provided in the closed section AT behind the traveling direction of the train 1, for example. It is connected to a transmission line 5b such as an optical cable.

各ＡＴＣ装置２ａ〜２ｃとＡＴＣ装置３ａ〜３ｃは無線を利用して列車１に搭載した車上装置に制御情報を送信するとともに車上装置から送られる絶対位置情報を基に列車在線情報を作成して列車１を制御する。この無線による情報の伝送には、図１に示すように、漏洩同軸ケーブル７ａ〜７ｃを利用したり、あるいは基地局と列車１に設けたアンテナを利用したりする。   Each ATC device 2a to 2c and ATC device 3a to 3c transmit control information to the on-board device mounted on the train 1 by using radio and create train on-line information based on the absolute position information sent from the on-board device. Then, the train 1 is controlled. For wireless transmission of information, as shown in FIG. 1, leaky coaxial cables 7 a to 7 c are used, or antennas provided in the base station and the train 1 are used.

この列車制御システムで、例えば列車１は閉そく区間ＡＴに進入して車上装置６から絶対位置情報が漏洩同軸ケーブル７ａに送信されると、主系のＡＴＣ装置２ａは漏洩同軸ケーブル７ａに送信された絶対位置情報を受信して列車在線情報を作成して列車１を制御する。また、主系のＡＴＣ装置２ａは列車在線情報を作成すると、列車位置情報や列車番号等を含む自装置の情報を、図２の情報伝送シーケンスに示すように、入出力チャネルｃｈ２から伝送路５ｂに送信して従系のＡＴＣ装置３ａの入出力チャネルｃｈ２と前方の閉そく区間ＢＴに設けた主系のＡＴＣ装置２ｂと従系のＡＴＣ装置３ｂの入出力チャネルｃｈ１に送る。従系のＡＴＣ装置３ａと閉そく区間ＢＴに設けた主系のＡＴＣ装置２ｂと従系のＡＴＣ装置３ｂは送られたＡＴＣ装置２ａの情報を記憶手段に保持する。   In this train control system, for example, when the train 1 enters the closed section AT and the absolute position information is transmitted from the onboard device 6 to the leaky coaxial cable 7a, the main ATC device 2a is sent to the leaky coaxial cable 7a. The train 1 is controlled by receiving the absolute position information and creating the train location information. Further, when the main ATC device 2a creates the train location information, the information of the own device including the train position information and the train number is transmitted from the input / output channel ch2 to the transmission line 5b as shown in the information transmission sequence of FIG. To the input / output channel ch1 of the slave ATC device 3a and the input / output channel ch1 of the master ATC device 2b and the slave ATC device 3b provided in the front block section BT. The slave ATC device 3a, the master ATC device 2b provided in the block section BT, and the slave ATC device 3b hold the information of the sent ATC device 2a in the storage means.

また、閉そく区間ＢＴに設けた主系のＡＴＣ装置２ｂは、自装置で作成した列車在線の有無等を含む情報を入出力チャネルｃｈ２から伝送路５ｃに送信して従系のＡＴＣ装置３ｂの入出力チャネルｃｈ２と前方の閉そく区間ＣＴに設けた主系のＡＴＣ装置２ｃと従系のＡＴＣ装置３ｃの入出力チャネルｃｈ１に送るとともに入出力チャネルｃｈ１から伝送路５ｂを介して閉そく区間ＡＴに設けた主系のＡＴＣ装置２ａと従系のＡＴＣ装置３ａの入出力チャネルｃｈ２と従系のＡＴＣ装置３ｂの入出力チャネルｃｈ１に送る。   In addition, the main ATC device 2b provided in the block section BT transmits information including the presence / absence of a train line created by the own device from the input / output channel ch2 to the transmission line 5c to enter the subordinate ATC device 3b. The output channel ch2 is sent to the input / output channel ch1 of the main ATC device 2c and the subordinate ATC device 3c provided in the front closed section CT, and is provided in the closed section AT from the input / output channel ch1 via the transmission line 5b. The data is sent to the input / output channel ch2 of the master ATC device 2a and the slave ATC device 3a and to the input / output channel ch1 of the slave ATC device 3b.

列車１が閉そく区間ＡＴから閉そく区間ＢＴに進入すると、閉そく区間ＢＴに設けた主系のＡＴＣ装置２ｂは漏洩同軸ケーブル７ｂに送信された絶対位置情報を受信して列車在線情報を作成して列車１を制御し、列車位置情報を含む自装置の情報を入出力チャネルｃｈ１から伝送路５ｂに送信し、入出力チャネルｃｈ２から伝送路５ｃに送信する。   When the train 1 enters the closed section BT from the closed section AT, the main ATC device 2b provided in the closed section BT receives the absolute position information transmitted to the leaky coaxial cable 7b, creates train standing line information, and trains 1 is transmitted, the information of the own apparatus including the train position information is transmitted from the input / output channel ch1 to the transmission path 5b, and is transmitted from the input / output channel ch2 to the transmission path 5c.

この情報伝送処理を閉そく区間ＡＴ〜ＣＴに設けた主系のＡＴＣ装置２ａ〜２ｃで逐次繰り返して行うことにより、例えば閉そく区間ＢＴに設けた主系のＡＴＣ装置２ｂの情報を従系のＡＴＣ装置３ｂと隣接する閉そく区間ＡＴと閉そく区間ＣＴに設けた主系のＡＴＣ装置２ａ，２ｃと従系のＡＴＣ装置２ｂ，２ｃで保持する。したがって列車１の在線を検出したＡＴＣ装置２ｂが停止しても列車在線情報を確実に保持することができる。   By repeating this information transmission processing sequentially in the main ATC devices 2a to 2c provided in the closed sections AT to CT, for example, information on the main ATC device 2b provided in the closed section BT is obtained as a slave ATC device. It is held by the master ATC devices 2a and 2c and the slave ATC devices 2b and 2c provided in the block section AT and block section CT adjacent to 3b. Therefore, even when the ATC device 2b that detects the presence of the train 1 stops, the train presence information can be reliably retained.

また、各閉そく区間ＡＴ〜ＣＴにそれぞれ設けた主系と従系のＡＴＣ装置２，３は独立した場所に設置できるから、各ＡＴＣ装置２，３を設置したいずれかの機器室全体が停電等でダウンして他系のＡＴＣ装置で在線状態を保持して列車１の走行位置を追跡できるから、列車１を安全に運行することができる。   In addition, since the primary and secondary ATC devices 2 and 3 provided in the respective closed sections AT to CT can be installed in independent locations, any one of the equipment rooms in which the ATC devices 2 and 3 are installed has a power failure or the like. Therefore, the train 1 can be operated safely because it can be tracked and the running position of the train 1 can be tracked with the ATC device of another system kept down.

さらに、各ＡＴＣ装置２，３に情報を伝送する２系統の入出力チャネルｃｈ１，ｃｈ２を設けたから、情報伝送のための同期を容易に取ることができる。   Furthermore, since two input / output channels ch1 and ch2 for transmitting information are provided to each ATC device 2 and 3, synchronization for information transmission can be easily achieved.
