Description

この発明は、無絶縁軌道回路を利用して列車検知を行うとともに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、特に地上装置の小型化とコスト低減化に関するものである。   The present invention relates to a train control device that performs train detection using an uninsulated track circuit and automatically controls the speed of a train below a speed limit, and more particularly to downsizing and cost reduction of a ground device.

無絶縁軌道回路を利用して列車検知を行うとともに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は、図6に示すように、各軌道回路3T,2T,1T,0Tの境界に分波器4a〜4cを介して列車検知用の送信器(以下、TD送信器という)21a〜21cと受信器(以下、TD受信器)22a〜22cを接続し、各TD送信器21a〜21cから軌道回路3T,2T,1Tに異なる周波数f3,f2,f1の列車検知信号を送信して同一周波数の列車検知信号の回り込みを防止している。そして例えば軌道回路2Tの列車進出側の境界に設けたTD送信器21bから送信した周波数f2の列車検知信号を軌道回路2Tの列車進入側に接続されたTD受信器22aで受信して列車検知リレー2TRを動作させているときは、軌道回路2Tに列車無しと判断し、列車1が軌道回路2Tに進入して軌道回路2Tに送信している列車検知信号をTD受信器22aで受信しなくなり、列車検知リレー2TRが復旧すると軌道回路2Tに列車1が在線したと判断している。   As shown in FIG. 6, the train control device that performs train detection using an uninsulated track circuit and automatically controls the train speed to be below the speed limit is a boundary between track circuits 3T, 2T, 1T, and 0T. Are connected to transmitters for train detection (hereinafter referred to as TD transmitters) 21a to 21c and receivers (hereinafter referred to as TD receivers) 22a to 22c through the duplexers 4a to 4c, respectively. The train detection signals having different frequencies f3, f2, and f1 are transmitted from 21c to the track circuits 3T, 2T, and 1T to prevent the train detection signals having the same frequency from wrapping around. For example, the train detection relay receives the train detection signal of the frequency f2 transmitted from the TD transmitter 21b provided at the train advance side boundary of the track circuit 2T by the TD receiver 22a connected to the train entrance side of the track circuit 2T. When operating 2TR, it is determined that there is no train in the track circuit 2T, and the train detection signal transmitted to the track circuit 2T by the train 1 entering the track circuit 2T is not received by the TD receiver 22a. When the train detection relay 2TR is restored, it is determined that the train 1 is on the track circuit 2T.

各軌道回路0T〜3Tの現示決定条件により列車1の速度を自動的に制限速度以下に制御するATC装置のATC送信器23は、列車検知信号とは異なる周波数を使用し、列車1が検知された軌道回路にのみ列車進出側の境界から送信し、不要な軌道回路に送信して混信することを防止している。   The ATC transmitter 23 of the ATC device that automatically controls the speed of the train 1 to be less than or equal to the speed limit according to the present determination conditions of each track circuit 0T to 3T uses a frequency different from the train detection signal, and the train 1 detects Only the track circuit that has been transmitted is transmitted from the boundary on the train advance side, and is transmitted to unnecessary track circuits to prevent interference.

It is disclosed.

特許文献1に示された列車制御装置は、互いに隣接する2つの無絶縁軌道回路の列車が進入してくる側の軌道回路(以下、進入側軌道回路という)の列車進入側境界と列車が進出していく側の軌道回路(以下、進出側軌道回路という)の列車進出側境界にTD信号とATC信号を受信する受信器を設け、2つの軌道回路の中央の位置にTD送信器とATC送信器を設け、TD送信器から2つの軌道回路にTD信号を送信し、進入側軌道回路で列車を検知したときに、AD送信器をATC送信器に切り換えて2つの軌道回路にATC信号を送信して、進入側軌道回路に送信したATC信号で列車の速度制御を行い、進出側軌道回路に送信したATC信号を列車検知に利用し、列車が進出側軌道回路に進入したことを検知すると2つの軌道回路の中央から送信していたATC信号を進出側軌道回路の列車進出側境界から送信するように切り換えて進出側軌道回路に在線している列車にATC信号を送信するようにしている。   In the train control device disclosed in Patent Document 1, the train entry side boundary of the track circuit (hereinafter referred to as the entry side track circuit) on the side where the trains of two non-insulated track circuits adjacent to each other enter and the train advances. A receiver for receiving the TD signal and the ATC signal is provided at the boundary of the train advancing side of the track circuit (hereinafter referred to as the advancing side track circuit), and the TD transmitter and the ATC transmission are provided at the center of the two track circuits. A TD signal is sent from the TD transmitter to the two track circuits, and when the train is detected by the approach side track circuit, the AD transmitter is switched to the ATC transmitter and the ATC signal is sent to the two track circuits. Then, the train speed is controlled by the ATC signal transmitted to the approach side track circuit, the ATC signal transmitted to the advance side track circuit is used for train detection, and it is detected that the train has entered the advance side track circuit. Of two track circuits And so as to transmit the ATC signal in the train being Zaisen the advanced side track circuit is switched so as to send the ATC signal that has been transmitted from the train advancing side boundary of the advancing-side track circuit from central.

特許文献2に示された列車制御装置は、複数の軌道回路の列車進出側境界に1つのTD送信器からスキャニング方式でTD信号を送信し、1つのTD送信器で各軌道回路の列車進入側境界からスキャニング方式でTD信号を受信し、ある軌道回路に列車が進入したことを検知するとその軌道回路を除いた他の軌道回路にTD信号のスキャニングを行い、列車を検知した軌道回路の列車進出側境界に各軌道回路との接続が切り換えられるATC送信器を接続し、列車進入側境界に各軌道回路との接続が切り換えられるATC受信器を接続して列車を検知した軌道回路にTD信号と同じ周波数のATC信号を送信して列車の速度を制御し、その軌道回路から列車が進出してATC受信器でATC信号を受信することにより列車無しを検知するようにしている。

図1はこの発明の列車制御装置の構成を示すブロック図である。列車制御装置は、列車1の位置を検知して列車1の速度を自動的に制限速度以下に制御するものであり、地上装置2と列車1に搭載された車上装置3を有する。   FIG. 1 is a block diagram showing the configuration of the train control device of the present invention. The train control device detects the position of the train 1 and automatically controls the speed of the train 1 to be equal to or lower than the speed limit, and includes a ground device 2 and an on-board device 3 mounted on the train 1.

地上装置2は、各無絶縁軌道回路3T〜0T,nTの境界に分波器4a〜4dを介して接続された送信器5a〜5dと受信器6a〜6d及び受信器6a〜6dに接続された列車検知リレー2TR〜0TR,nTRを有する。送信器5a〜5dは各軌道回路3T〜0Tの現示条件に応じた列車制御情報を入力して、各軌道回路3T〜0T,nTの配列順が符号や番号で特定されるように規則的に定められ、例えば番号で特定したとすると、起点から遠ざかるにしたがって小さな番号が割り振られた軌道回路識別情報及び制限速度情報を含むATC信号を軌道回路3T〜0T毎に異なる周波数f3〜f0で生成して分波器4a〜4dを介して各軌道回路3T〜0Tの列車進出側の境界から送信する。このATC信号は、符号変調、周波数変調、AM変調、2波の信号組み合わせなど様々な方式で実現できる。受信器6a〜6dは軌道回路2T〜0T,nTに送信されたATC信号を各軌道回路2T〜0T,nTの列車進入側の境界で受信し、ATC信号の受信の有無により列車検知リレー2TR〜0TR,nTRを駆動して軌道回路2T〜0T,nTに列車1が在線するか否を検知する。   The ground device 2 is connected to transmitters 5a to 5d, receivers 6a to 6d, and receivers 6a to 6d connected to the boundaries of the non-insulated track circuits 3T to 0T and nT via branching filters 4a to 4d. Train detection relays 2TR to 0TR, nTR. The transmitters 5a to 5d receive train control information corresponding to the present conditions of the track circuits 3T to 0T, and are regularly arranged so that the arrangement order of the track circuits 3T to 0T and nT is specified by a code or a number. For example, if specified by a number, an ATC signal including track circuit identification information and speed limit information allocated with a smaller number as the distance from the starting point is generated at different frequencies f3 to f0 for each track circuit 3T to 0T. Then, the signals are transmitted from the boundaries on the train advance side of the track circuits 3T to 0T via the duplexers 4a to 4d. The ATC signal can be realized by various methods such as code modulation, frequency modulation, AM modulation, and two-wave signal combination. The receivers 6a to 6d receive the ATC signals transmitted to the track circuits 2T to 0T and nT at the boundaries on the train entry side of the track circuits 2T to 0T and nT. 0TR and nTR are driven to detect whether or not the train 1 is on the track circuits 2T to 0T and nT.

車上装置3は、図2のブロック図に示すように、受信器7とデータ記憶部8と処理部9と速度検出器10と速度照査部11及び速度制御部12を有する。受信器7は受電器13を介して軌道回路3T〜0T,nTに送信されているATC信号を受信するものであり、周波数f0〜fnのATC信号を受信するf0受信部14a〜fn受信部14nと受信情報選択部15を有する。受信情報選択部15はf0受信部14a〜fn受信部14nで受信した各周波数のATC信号に含まれる軌道回路識別情報のなかで最も大きい番号の軌道回路識別情報を有するATC信号を選択する。データ記憶部8には各種制御データがあらかじめ格納されている。処理部9は受信情報選択部8で選択したATC信号の制限速度情報とデータ記憶部8に記憶した制御データを参照して列車1の速度パターンや固定速度情報を作成する。速度検出部10は列車1の車軸に設けられた速度発電機16からの速度情報を入力して列車1の速度を検出する。速度照査部11は処理部9で作成した速度パターンと速度検出器10で検出している列車1の速度とを照合して照査する。速度制御部12は速度照査部11の照査結果によりブレーキ装置等を制御して列車1の速度が制限速度以下になるように制御する。   As shown in the block diagram of FIG. 2, the on-board device 3 includes a receiver 7, a data storage unit 8, a processing unit 9, a speed detector 10, a speed checking unit 11, and a speed control unit 12. The receiver 7 receives the ATC signal transmitted to the track circuits 3T to 0T and nT via the power receiver 13, and receives the ATC signal having the frequency f0 to fn. And a reception information selection unit 15. The reception information selection unit 15 selects the ATC signal having the track circuit identification information having the highest number among the track circuit identification information included in the ATC signals of the respective frequencies received by the f0 reception unit 14a to fn reception unit 14n. Various control data are stored in the data storage unit 8 in advance. The processing unit 9 creates the speed pattern and fixed speed information of the train 1 with reference to the speed limit information of the ATC signal selected by the reception information selection unit 8 and the control data stored in the data storage unit 8. The speed detector 10 inputs speed information from a speed generator 16 provided on the axle of the train 1 and detects the speed of the train 1. The speed checking unit 11 checks the speed pattern created by the processing unit 9 against the speed of the train 1 detected by the speed detector 10. The speed control unit 12 controls the brake device and the like according to the check result of the speed check unit 11 so that the speed of the train 1 is equal to or lower than the speed limit.

この列車制御装置で列車1を検知して列車1の速度を制御するときの動作を図3のフローチャートを参照して説明する。   The operation when the train control apparatus detects the train 1 and controls the speed of the train 1 will be described with reference to the flowchart of FIG.

列車1が例えば軌道回路3Tから軌道回路2Tに進入すると(ステップS1)、送信器5bから軌道回路2Tに送信されている周波数f2のATC信号を受信器6aで受信しなくなり、軌道回路2Tに列車1が進入したことを検知する(ステップS2)。軌道回路2Tに進入した列車1に搭載した車上装置3の受信器7は軌道回路2Tに送信されているATC信号を受信する(ステップS3)。この受信器7で受信するATC信号には、各軌道回路が無絶縁で軌条絶縁が無いことから軌道回路2Tに送信された周波数f2のATC信号以外にも前方の軌道回路1T〜nTに送信している周波数f1,f0,fnのATC信号もf0受信部14a〜fn受信部14nで受信する。このf0受信部14a〜fn受信部14nで受信した各周波数のATC信号を受信情報選択部15に出力する。受信情報選択部15は入力した各周波数のATC信号を解読して、ATC信号に含まれる軌道回路識別情報のなかで最も大きい番号の軌道回路識別情報を有するATC信号を選択し、選択したATC信号の制限速度情報を処理部9に出力する(ステップS4)。これは地上装置2の送信器5a〜5dで生成するATC信号に含まれる軌道回路識別情報は、各軌道回路3T〜0T,nTの配置が特定されるように規則的に定められ、例えば番号で表する場合は、起点から遠ざかるにしたがって小さな番号が割り振られているため、列車1が軌道回路2Tに進入したときに受信したATC信号のなかで軌道回路識別情報が最も大きい番号のATC信号が軌道回路2Tに送信されたATC信号になるからである。   When the train 1 enters the track circuit 2T from, for example, the track circuit 3T (step S1), the ATC signal of the frequency f2 transmitted from the transmitter 5b to the track circuit 2T is not received by the receiver 6a, and the train is transferred to the track circuit 2T. 1 is detected (step S2). The receiver 7 of the on-board device 3 mounted on the train 1 entering the track circuit 2T receives the ATC signal transmitted to the track circuit 2T (step S3). The ATC signal received by the receiver 7 is transmitted to the front track circuits 1T to nT in addition to the ATC signal having the frequency f2 transmitted to the track circuit 2T because each track circuit is not insulated and has no rail insulation. The ATC signals having the frequencies f1, f0, and fn are also received by the f0 receivers 14a to 14n. The ATC signal of each frequency received by the f0 receivers 14a to 14n is output to the reception information selector 15. The reception information selection unit 15 decodes the input ATC signal of each frequency, selects the ATC signal having the largest number of track circuit identification information among the track circuit identification information included in the ATC signal, and selects the selected ATC signal. Is output to the processing unit 9 (step S4). The track circuit identification information included in the ATC signals generated by the transmitters 5a to 5d of the ground device 2 is regularly determined so that the arrangement of the track circuits 3T to 0T and nT is specified, for example, by numbers In this case, since a smaller number is assigned as the distance from the starting point increases, the ATC signal having the largest track circuit identification information among the ATC signals received when the train 1 enters the track circuit 2T is the track. This is because the ATC signal transmitted to the circuit 2T is obtained.

処理部9は入力したATC信号の制限速度情報とデータ記憶部8に記憶した制御データを参照して列車1の速度パターンを作成して速度照査部11に出力する(ステップS5)。速度照査部11は入力した速度パターンと速度検出器10で検出している列車1の速度とを照合して照査し、照査結果を速度制御部12に出力する。速度制御部12は入力した照査結果によりブレーキ装置等を制御して列車1の速度が制限速度以下になるように制御する(ステップS6)。   The processing unit 9 creates a speed pattern of the train 1 with reference to the input speed limit information of the ATC signal and the control data stored in the data storage unit 8 and outputs it to the speed checking unit 11 (step S5). The speed checking unit 11 compares the input speed pattern with the speed of the train 1 detected by the speed detector 10 and checks the result, and outputs the checking result to the speed control unit 12. The speed control unit 12 controls the brake device and the like based on the input verification result so as to control the speed of the train 1 to be equal to or lower than the speed limit (step S6).

このように送信器5a〜5dから各軌道回路3T〜0Tに送信するATC信号を列車検知用に使用することにより、地上装置2に列車検知用の送信器を設けないで済み、地上装置2の小型化を図り、コストを低減することができる。   Thus, by using the ATC signal transmitted from the transmitters 5a to 5d to the track circuits 3T to 0T for train detection, the ground device 2 does not have to be provided with a train detection transmitter. The size can be reduced and the cost can be reduced.

また、各軌道回路3T〜0Tに送信するATC信号に含まれる軌道回路識別情報を各軌道回路3T〜0T,nTの配列順が特定されるように定めることにより、列車1が進入した軌道回路に送信されているATC信号以外にも前方の軌道回路に送信しているATC信号を車上装置3で受信しても、列車1が進入した軌道回路に送信されているATC信号を確実に判別して他の軌道回路に送信されているATC信号と誤認することを防止することができる。   Further, the track circuit identification information included in the ATC signal transmitted to each track circuit 3T to 0T is determined so that the arrangement order of each track circuit 3T to 0T and nT is specified, so that the track circuit into which the train 1 has entered is determined. In addition to the ATC signal being transmitted, even if the on-board device 3 receives an ATC signal transmitted to the track circuit ahead, the ATC signal transmitted to the track circuit into which the train 1 has entered is reliably determined. Thus, it is possible to prevent the ATC signal being transmitted to another track circuit from being mistaken.

前記説明では、列車1が進入した軌道回路に送信されているATC信号と他の軌道回路に送信されているATC信号を判別するために、地上装置2の送信器5a〜5dで生成するATC信号に含まれる軌道回路識別情報を、各軌道回路3T〜0T,nTの配列順が特定されるように定めた場合について説明したが、このATC信号を判別するための各軌道回路3T〜0T,nTの配列順を示す情報を車上装置3に設けて、列車1が進入した軌道回路に送信されているATC信号と他の軌道回路に送信されているATC信号を判別するようにしても良い。   In the above description, the ATC signal generated by the transmitters 5a to 5d of the ground device 2 in order to discriminate between the ATC signal transmitted to the track circuit in which the train 1 has entered and the ATC signal transmitted to another track circuit. The track circuit identification information included in the track circuit 3T to 0T and nT has been described so that the arrangement order of the track circuits 3T to 0T and nT is specified, but each track circuit 3T to 0T and nT for determining the ATC signal is described. May be provided in the on-board device 3 to discriminate between the ATC signal transmitted to the track circuit in which the train 1 has entered and the ATC signal transmitted to another track circuit.

この場合、図4のブロック図に示す車上装置3のデータ記憶部8には、各種制御データとともに、図5の模式図に示す軌道回路情報テーブル17をあらかじめ記憶しておく。この軌道回路情報テーブル17には、軌道回路3T〜0T,nTを特定する軌道回路IDが各軌道回路3T〜0T,nTの配列順に規則的に記憶してある。   In this case, the track memory information table 17 shown in the schematic diagram of FIG. 5 is stored in advance in the data storage unit 8 of the on-board device 3 shown in the block diagram of FIG. 4 together with various control data. The track circuit information table 17 regularly stores track circuit IDs for specifying the track circuits 3T to 0T and nT in the order of the track circuits 3T to 0T and nT.

地上装置2の送信器5a〜5dは、接続された軌道回路3T〜0T,nTを特定する軌道回路IDを含むATC信号を軌道回路3T〜0T毎に異なる周波数f3〜f0で生成して分波器4a〜4dを介して各軌道回路3T〜0Tに送信する。列車1が例えば軌道回路3Tから軌道回路2Tに進入して、軌道回路2Tに進入した列車1に搭載した車上装置3の受信器7で軌道回路2Tに送信された周波数f2のATC信号とともに前方の軌道回路1T〜nTに送信している周波数f1,f0,fnのATC信号も受信すると、受信情報選択部15は受信した各ATC信号を解読して軌道回路IDを抽出し、抽出した各軌道回路IDによりデータ記憶部8に記憶した軌道回路情報テーブル17を検索し、抽出した各軌道回路IDのなかで軌道回路の配列順が一番先頭にある軌道回路IDを含むATC信号を選択し、選択したATC信号の制限速度情報を処理部9に出力する。   The transmitters 5a to 5d of the ground device 2 generate and demultiplex ATC signals including track circuit IDs for specifying the track circuits 3T to 0T and nT connected to the track circuits 3T to 0T at different frequencies f3 to f0. It transmits to each track circuit 3T-0T via the devices 4a-4d. For example, the train 1 enters the track circuit 2T from the track circuit 3T and moves forward along with the ATC signal of the frequency f2 transmitted to the track circuit 2T by the receiver 7 of the on-board device 3 mounted on the train 1 that has entered the track circuit 2T. When receiving the ATC signals of the frequencies f1, f0, and fn transmitted to the track circuits 1T to nT, the reception information selection unit 15 decodes each received ATC signal to extract the track circuit ID, and extracts each track The track circuit information table 17 stored in the data storage unit 8 is searched by the circuit ID, and the ATC signal including the track circuit ID in which the track circuit array order is first in the extracted track circuit IDs is selected. The speed limit information of the selected ATC signal is output to the processing unit 9.

このようにして地上装置2の送信器5a〜5dは、軌道回路3T〜0Tを特定する軌道回路IDを含むATC信号を送信すれば良いから、地上から列車1に送信する情報量を低減することができる。   In this way, the transmitters 5a to 5d of the ground device 2 only need to transmit the ATC signal including the track circuit ID that identifies the track circuits 3T to 0T, so that the amount of information transmitted from the ground to the train 1 is reduced. Can do.

前記説明では送信器5a〜5dからデジタルのATC信号を軌道回路3T〜0Tに送信する場合について説明したが、アナログのATC信号を送信する場合も同様に適用することができる。   In the above description, the case where the digital ATC signals are transmitted from the transmitters 5a to 5d to the track circuits 3T to 0T has been described. However, the present invention can be similarly applied to the case where analog ATC signals are transmitted.
