Description

この発明は、列車の速度を自動的に制限速度以下に制御する列車制御装置、特に列車の間隔を短縮して高密度運転を図ることに関するものである。 The present invention relates to a train control apparatus that automatically controls the speed of a train below a speed limit, and more particularly to high-density operation by shortening the train interval.

列車の速度を自動的に制限速度以下に制御する自動列車制御装置（以下、ＡＴＣ装置という）は、あらかじめ先行列車との間隔と曲線や分岐等の進路の条件等により定まる停止目標位置と現在の在線位置を示す符号化した列車制御情報を伝送し、車上装置は受信した列車制御情報から算出される停止目標位置までの照査速度パターンに基づき連続的に列車を減速する方法である。 An automatic train control device (hereinafter referred to as an ATC device) that automatically controls the speed of a train below the speed limit is based on the current stop target position determined by the distance from the preceding train and the conditions of the route such as a curve or a branch. The encoded train control information indicating the standing line position is transmitted, and the on-board device continuously decelerates the train based on the verification speed pattern to the stop target position calculated from the received train control information.

このＡＴＣ装置で地上と列車との間で情報を伝送するためにレールやループアンテナを使用せずにトランスポンダを使用した自動列車制御装置が、例えば特許文献１に開示されている。特許文献１に示された自動列車制御装置は、地上装置で複数の閉そく区間毎に列車の規制速度を決定し、決定した規制速度を示す信号を各閉そく区間の進行方向手前側の境界付近に設けたトランスポンダからなる地上子から列車に向けて送信し、この閉そく区間毎に送信される規制速度を示した信号を列車に搭載した車上装置はトランスポンダからなる車上子を介して規制速度以下で列車を制御している。また、地上子で車上子から送信された列車固有番号を有する信号すると地上装置はその地上子が設けられた閉そく区間に列車が進入したことを検知する。そして地上装置は管轄する区間のどの閉そく区間に列車が在線するかにより各閉そく区間の規制速度を決定している。
特許文献１特開２００３−１１８１９号公報 For example, Patent Document 1 discloses an automatic train control device that uses a transponder without using a rail or a loop antenna to transmit information between the ground and a train using this ATC device. The automatic train control device disclosed in Patent Document 1 determines the train speed limit for each of the plurality of block sections in the ground device, and a signal indicating the determined control speed is near the boundary on the front side in the traveling direction of each block section. The on-board device equipped with a signal indicating the regulated speed transmitted for each block section is transmitted to the train from the ground element consisting of the installed transponder, and is below the regulated speed via the vehicle element consisting of the transponder. The train is in control. Further, when a signal having a train unique number transmitted from the vehicle upper element is transmitted from the ground element, the ground device detects that the train has entered a closed section where the ground element is provided. And the ground apparatus determines the regulation speed of each block section depending on which block section of the section it has jurisdiction over.

この列車制御装置で後続する列車１ｂの速度を制限速度以下に制御するときの処理を図４〜図７のフローチャートを参照して説明する。 Processing when the speed of the following train 1b is controlled to be equal to or lower than the speed limit by the train control device will be described with reference to the flowcharts of FIGS.

例えば、図１に示すように、定点４ａに設けられた定点情報送受信装置５ａの列車情報送受信部１６は列車１ａが定点４ａに達して車上装置２の送受信部８から例えば列車１ａの先頭車両に設けた車上子１３で送信している列車情報を受信すると、受信した列車情報を列車検知部１７に送る（ステップＳ１）。列車検知部１７は送られた列車情報に含まれる列車識別番号を検出すると、その列車１ａが定点４ａに進入したことを検知し、列車検知信号を停止位置情報作成部１８と定点情報作成部２３に送る（ステップＳ２）。停止位置情報作成部１８は列車検知信号が送られると列車情報送受信部１６で受信した列車情報に含まれる列車長Ｌ１とあらかじめ設定された余裕距離Ｌ２により定点４ａを基準とした後続列車１ｂの停止位置ＳＰまでの距離Ｌ３＝（Ｌ１＋Ｌ２）を算出し、算出した距離Ｌ３と基点から定点４ａまでの距離情報Ｌａにより後続列車１ｂの停止位置情報Ｌｓｐ＝（Ｌａ−Ｌ３）を算出して中継情報送信部１９に送る（ステップＳ３）。中継情報送信部１９は送られた停止位置情報Ｌｓｐを伝送路１５ａを介して外方の定点４ｂに設けられた定点情報送受信装置５ｂに送信する（ステップＳ４）。 For example, as shown in FIG. 1, the train information transmission / reception unit 16 of the fixed point information transmission / reception device 5a provided at the fixed point 4a has a train 1a that reaches the fixed point 4a and the transmission / reception unit 8 of the on-board device 2, for example, the leading vehicle of the train 1a When the train information transmitted by the vehicle upper 13 provided in the vehicle is received, the received train information is sent to the train detection unit 17 (step S1). When the train detection unit 17 detects a train identification number included in the transmitted train information, the train detection unit 17 detects that the train 1a has entered the fixed point 4a, and transmits a train detection signal to the stop position information generation unit 18 and the fixed point information generation unit 23. (Step S2). When the train detection signal is sent, the stop position information creation unit 18 stops the subsequent train 1b based on the fixed point 4a based on the train length L1 included in the train information received by the train information transmission / reception unit 16 and the preset margin distance L2.

Is received and sent to the relay information updating unit 21 (step S11). The relay information update unit 21 compares the sent stop position information Lsp with the stop position information previously received and stored in the relay information storage unit 22 (step S12), and the sent stop position information Lsp has been received before. When the stop position information is different from the stop position information, the stop position information stored in the relay information storage unit 22 is updated with the sent stop position information Lsp, and the updated stop position information Lsp is sent to the relay information transmitting unit 19 (step S13). When the stop position information Lsp is sent from the relay information updating unit 21, the relay information transmitting unit 19 transmits the sent stop position information Lsp to the outside fixed point information transmitting / receiving device 5c via the transmission line 15b (step S14). . Similarly to the fixed point information transmitting / receiving apparatus 5b, the fixed point information transmitting / receiving apparatus 5c relays the stop position information Lsp, transmits the stop position information Lsp to the fixed point information transmitting / receiving apparatus 5d, and stops at the relay information storage unit 22 of the fixed point information transmitting / receiving apparatus 5d. The position information Lsp is stored.

この状態で後続の列車１ｂが定点４ｄに達して、図６のフローチャートに示すように、定点情報送受信装置５ｄの列車情報送受信部１６で後続列車１ｂから送信している列車情報を受信すると、受信した列車情報を列車検知部１７に送る（ステップＳ２１）。列車検知部１７は送られた列車情報に含まれる列車識別番号を検出すると、その列車１ｂが定点４ｄに進入したことを検知し、列車検知信号を停止位置情報作成部１８と定点情報作成部２３に送る（ステップＳ２２）。定点情報作成部２３は列車検知信号が送られると中継情報記憶部２２に記憶している停止位置情報Ｌｓｐと定点４ｄの位置情報Ｌｄを有する定点情報を作成して列車情報送受信部１６に送る（ステップＳ２３）。列車情報送受信部１６は送られた定点情報を地上子６を介して列車１ｂに送信する（ステップＳ２４）。また、停止位置情報作成部１８は列車検知部１７から列車検知信号が送られると列車情報送受信部１６で受信した列車情報に含まれる列車長とあらかじめ設定された余裕距離により定点４ｄを基準とした後続列車の停止位置情報を作成して中継情報送信部１９に送る（ステップＳ２５）。中継情報送信部１９は送られた停止位置情報を伝送路１５ｄを介して外方の定点に設けられた定点情報送受信装置に送信する（ステップＳ２６）。 In this state, when the subsequent train 1b reaches the fixed point 4d and receives the train information transmitted from the subsequent train 1b by the train information transmitting / receiving unit 16 of the fixed point information transmitting / receiving device 5d as shown in the flowchart of FIG. Train information sent to the train detector 17 (step S21). When the train detection unit 17 detects a train identification number included in the transmitted train information, the train detection unit 17 detects that the train 1b has entered the fixed point 4d, and transmits a train detection signal to the stop position information generation unit 18 and the fixed point information generation unit 23. (Step S22). When a train detection signal is sent, the fixed point information creating unit 23 creates fixed point information having stop position information Lsp stored in the relay information storage unit 22 and position information Ld of the fixed point 4d and sends the fixed point information to the train information transmitting / receiving unit 16 ( Step S23). The train information transmitting / receiving unit 16 transmits the sent fixed point information to the train 1b via the ground element 6 (step S24). When the train detection signal is sent from the train detection unit 17, the stop position information creation unit 18 uses the fixed point 4d as a reference based on the train length included in the train information received by the train information transmission / reception unit 16 and a preset margin distance. Stop position information of the following train is created and sent to the relay information transmitting unit 19 (step S25). The relay information transmitting unit 19 transmits the sent stop position information to the fixed point information transmitting / receiving apparatus provided at the fixed point outside via the transmission path 15d (step S26).

後続の列車１ｂの送受信部８は、図７のフローチャートに示すように、定点４ｄに設けた定点情報送受信装置５ｄから送信した定点情報を車上子１３を介して受信すると、受信した定点情報を位置検出部１０と速度パターン作成部１１に送る（ステップＳ３１）。位置検出部１０は速度発電機１４からの速度情報から検出している列車１ｂの走行位置を送られた定点情報に有する定点４ｄの位置情報Ｌｄにより補正して速度パターン作成部１１に送る（ステップＳ３２）。速度パターン作成部１１は送られた列車１ｂの走行位置Ｌｄと定点情報に有する停止位置情報Ｌｓｐにより停止位置ＳＰに列車１ｂを停止させるための速度パターンを作成して速度制御部１２に送る（ステップＳ３３）。速度制御部１２は送られた速度パターンと位置検出部１０から送られる列車１ｂの走行位置及び速度検出部９で検出している速度により列車１ｂの走行速度を制御する（ステップＳ３４）。 When the transmission / reception unit 8 of the succeeding train 1b receives the fixed point information transmitted from the fixed point information transmission / reception device 5d provided at the fixed point 4d via the vehicle upper part 13 as shown in the flowchart of FIG. 7, the received fixed point information is received. The data is sent to the position detector 10 and the speed pattern generator 11 (step S31). The position detection unit 10 corrects the traveling position of the train 1b detected from the speed information from the speed generator 14 with the position information Ld of the fixed point 4d included in the received fixed point information, and sends the corrected position information to the speed pattern generation unit 11 (step) S32). The speed pattern creation unit 11 creates a speed pattern for stopping the train 1b at the stop position SP based on the travel position Ld of the train 1b and the stop position information Lsp included in the fixed point information, and sends the speed pattern to the speed control unit 12 (step). S33). The speed control unit 12 controls the traveling speed of the train 1b based on the sent speed pattern, the traveling position of the train 1b sent from the position detecting unit 10, and the speed detected by the speed detecting unit 9 (step S34).

このようにして後続の列車１ｂは先行する列車１ａの位置に応じた停止位置を得ることができ、その停止位置までの距離に応じた速度パターンにより走行速度を制御することができ、例えば図８に示すように、定点４ａを先行する列車１ａが走行しているときに、外方の定点４ｂに達した後続の列車１ｂを定点４ｂを越えて進行させることができ、列車間隔を短縮して列車１の運行の高密度化を図ることができる。 In this way, the succeeding train 1b can obtain a stop position corresponding to the position of the preceding train 1a, and the traveling speed can be controlled by a speed pattern corresponding to the distance to the stop position. For example, FIG. As shown in Fig. 4, when the train 1a preceding the fixed point 4a is traveling, the subsequent train 1b that has reached the outer fixed point 4b can be advanced beyond the fixed point 4b, and the train interval can be shortened. The density of operation of the train 1 can be increased.

また、定点情報送受信装置５ａで算出した停止位置情報Ｌｓｐを外方の定点情報送受信装置５ｂ〜５ｄに伝送した状態で後続の列車１ｂが定点４ｄに達したとき、定点情報送受信装置５ｄから定点情報が列車１ｂに送信されなく、図９に示すように、列車１ｂの速度パターン作成部１１で定点情報送受信装置５ａにより算出した停止位置情報Ｌｓｐに基づく速度パターンＡが作成されなかった場合、列車１ｂは定点４ｂの定点情報送受信装置５ｂで算出した停止位置情報に基づく速度パターンＢにより速度を制御しているから安全性を損なわないで済む。 When the following train 1b reaches the fixed point 4d in a state where the stop position information Lsp calculated by the fixed point information transmitting / receiving device 5a is transmitted to the external fixed point information transmitting / receiving devices 5b to 5d, the fixed point information is transmitted from the fixed point information transmitting / receiving device 5d. Is not transmitted to the train 1b, and as shown in FIG. 9, when the speed pattern A based on the stop position information Lsp calculated by the fixed point information transmitting / receiving device 5a is not created by the speed pattern creating unit 11 of the train 1b, the train 1b Since the speed is controlled by the speed pattern B based on the stop position information calculated by the fixed point information transmitting / receiving device 5b of the fixed point 4b, safety is not impaired.

前記説明では列車情報を列車１ａの先頭車両に設けた車上子１３から送信する場合について説明したが、列車情報を列車１ａの先頭車両に設けた車上子１３と列車１ａの後尾車両に設けた地上子からも送信することにより、図１０（ａ）に示すように、列車１ａの先頭車両が定点４ａに達したときに定点情報送受信装置５ａで列車長Ｌ１と余裕距離Ｌ２により定めた後続列車１ｂの停止位置ＳＰに基づく停止位置情報Ｌｓｐを外方の定点情報送受信装置５ｂ，５ｃに送信し、列車１ａの後尾車両が定点４ａを通過して定点情報送受信装置５ａで後尾車両に設けた車上子から列車情報を受信したときに、図１０（ｂ）に示すように、余裕距離Ｌ２により定めた後続列車１ｂの停止位置ＳＰ１に基づく停止位置情報を外方の定点情報送受信装置５ｂ，５ｃに送信するようにしても良い。このように列車１ａの後尾車両からも列車情報を送信することにより、後続列車１ｂで速度を制御する速度パターンを列車１ａが定点４ａを抜けた後に定点４ｂに達したときに速度パターンＡから速度パターンＣに変更して速度制御をきめ細かく行うことができ、列車１を高密度で安定して走行させることができる。 In the above description, the train information is transmitted from the vehicle upper 13 provided in the leading vehicle of the train 1a. However, the train information is provided in the vehicle upper 13 provided in the leading vehicle of the train 1a and the rear vehicle of the train 1a. As shown in FIG. 10 (a), when the leading vehicle of the train 1a reaches the fixed point 4a, the subsequent point determined by the fixed point information transmitting / receiving device 5a by the train length L1 and the margin distance L2 Stop position information Lsp based on the stop position SP of the train 1b is transmitted to the outer fixed point information transmitting / receiving devices 5b and 5c, and the rear vehicle of the train 1a passes through the fixed point 4a and is provided to the rear vehicle by the fixed point information transmitting / receiving device 5a. When the train information is received from the vehicle upper member, as shown in FIG. 10B, the stop position information based on the stop position SP1 of the succeeding train 1b determined by the margin distance L2 is transmitted to the outside fixed point information transmitting / receiving device 5. , It may be transmitted to 5c. In this way, by transmitting train information also from the rear vehicle of the train 1a, the speed pattern for controlling the speed by the succeeding train 1b is changed from the speed pattern A when the train 1a reaches the fixed point 4b after passing through the fixed point 4a. The speed can be finely controlled by changing to the pattern C, and the train 1 can be driven stably with high density.
