Description

この発明は、軌道回路を利用して地上で列車の速度を検出し、検出した速度で列車の速度発電機により検出した速度を補正して列車の走行を制御する列車制御装置に関するものである。   The present invention relates to a train control device that detects the speed of a train on the ground using a track circuit and corrects the detected speed by a train speed generator to control the traveling of the train.

列車の速度を制御するため、列車の車軸に設けた速度発電機から出力する交流信号により速度を検出したり、非特許文献１に示すように、列車が制限速度Ｖで走行したときの通過時間があらかじめ車上装置に設定された標準時間Ｔｓになるように定めた間隔Ｌで速度照査用の２つの地上子をレールに沿って設置し、列車に搭載された車上子が速度照査用の２つの地上子間を通過した時間Ｔ１を計測し、通過時間Ｔ１と設定されている標準時間Ｔｓとを比較し、通過時間Ｔ１が標準時間Ｔｓより短いときは、列車が制限速度Ｖ以上で走行していると判定し、通過時間Ｔ１が標準時間Ｔｓより長いときは、列車が制限速度Ｖ以下で走行していると判定するようにしている。
ＡＴＳ／ＡＴＣ 社団法人日本鉄道電気技術協会 平成５年 In order to control the speed of the train, the speed is detected by an AC signal output from a speed generator provided on the axle of the train, or the transit time when the train travels at the speed limit V as shown in Non-Patent Document 1. Is installed along the rails at the interval L determined in advance so as to be the standard time Ts set in the on-board device, and the on-board element mounted on the train is used for the speed check. The time T1 that has passed between the two ground elements is measured, the passage time T1 is compared with the set standard time Ts, and when the passage time T1 is shorter than the standard time Ts, the train travels at the speed limit V or higher. When the passage time T1 is longer than the standard time Ts, it is determined that the train is traveling at the speed limit V or less.

列車の車軸に設けた速度発電機から出力する交流信号により速度を検出する方法は、車輪が磨耗して大きさが変化すると検出している速度に誤差が生じてしまう。このため速度発電機で検出している速度を補正する必要がある。   In the method of detecting the speed by the AC signal output from the speed generator provided on the train axle, an error occurs in the detected speed when the wheel wears and the size changes. For this reason, it is necessary to correct the speed detected by the speed generator.

また、速度照査用の２つの地上子を使用して速度を検出する場合は、速度照査用の２つの地上子をレールに沿って設置する必要があるとともに、２つの地上子を通過したときしか速度を得ることができず、列車が走行する全区間の速度を連続して得ることはできないという短所がある。   In addition, when detecting the speed using two ground checkers for speed verification, it is necessary to install two ground checkers for speed check along the rail and only when two ground checkers are passed. There is a disadvantage that the speed cannot be obtained and the speeds of all sections where the train travels cannot be obtained continuously.

この発明は、このような短所を改善し、速度照査用の地上子を設けずに列車の速度を地上で精度良く検出するとともに、検出した速度を列車に送信して速度発電機で検出している速度を補正することができる列車制御装置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 detects the speed of the train accurately on the ground without providing a ground for speed check, and transmits the detected speed to the train and detects it with a speed generator. It is an object of the present invention to provide a train control device that can correct a certain speed.

A signal transmitter), a train detection receiver (hereinafter referred to as a TD signal receiver) connected to the boundary of each track circuit on the train advance side, and an on-vehicle information transmission transmitter (hereinafter referred to as an ATC signal transmission). The TD signal transmitter includes an approach-side track circuit train detection signal indicating that a train has entered the train approach-side track circuit of the connected track circuit, and a track of the train entrance-side track circuit. A train detection signal (hereinafter referred to as a TD signal) including track circuit information having a length is generated and transmitted to the track circuit. The TD signal receiver includes a train detection unit, a track information detection unit, a timing unit, and a speed calculation unit. The train detector is receiving the TD signal Whether or not a train is on the track circuit is detected based on the presence or absence of the train, and when the train enters the track circuit, a train detection signal is sent to the TD signal transmitter connected to the track circuit on the train advance side to detect track information The unit detects track circuit information from the received TD signal, and the time measuring unit receives an entry side track circuit train detection signal indicating that the train has entered the track circuit on the train entry side based on the track circuit information detected by the track information detection unit. When it is sent, it starts timing, and when it detects that a train has entered the track circuit connected by the train detection unit, it stops timing, and the speed calculation unit uses the track circuit information detected by the track information detection unit. The average speed when the train is traveling on the track circuit on the train approach side is calculated from the track length of the track circuit on the train approach side included and the travel time of the train timed by the timekeeping unit, and is sent to the ATC signal transmitter. Send ATC The signal transmitter generates an ATC signal including the control information and the average speed sent from the TD signal receiver and transmits the ATC signal to the track circuit. The on-board device transmits the train information included in the ATC signal received for each track circuit. The speed detected by the signal from the speed generator is corrected by the average speed obtained from the average speed and the speed detected by the signal from the speed generator.

前記車上装置は、軌道回路毎に受信したＡＴＣ信号に含まれる列車の平均速度と速度発電機からの信号により検出した速度から求めた平均速度を軌道回路毎に記憶することが望ましい。   It is desirable that the on-board device stores, for each track circuit, the average speed obtained from the average speed of the train included in the ATC signal received for each track circuit and the speed detected by the signal from the speed generator.

この発明は、各軌道回路を走行しているときの列車の平均速度を地上に設けたＴＤ信号送信器で求めてＡＴＣ信号に含ませて列車に送信し、列車の車上装置は速度発電機からの信号により検出した速度の平均速度を求めて地上で算出した平均速度との速度差を算出して速度発電機からの信号により検出した速度を修正するから、車輪の磨耗によって大きさが変化して速度発電機からの信号により検出した速度に誤差が生じても、その誤差を修正することができ、列車の速度を精度良く検出することができるとともに速度修正用の地上子を設けないですみ、設備費を低減することができる。   According to the present invention, the average speed of a train when traveling on each track circuit is obtained by a TD signal transmitter provided on the ground and included in an ATC signal and transmitted to the train. Since the average speed of the speed detected by the signal from the car is calculated and the speed difference from the average speed calculated on the ground is calculated and the speed detected by the signal from the speed generator is corrected, the magnitude changes due to wheel wear. Even if an error occurs in the speed detected by the signal from the speed generator, the error can be corrected, the speed of the train can be detected with high accuracy, and a ground element for speed correction is not provided. Therefore, the equipment cost can be reduced.

また、軌道回路毎に受信したＡＴＣ信号に含まれる列車の平均速度と速度発電機からの信号により検出した速度から求めた平均速度を軌道回路毎に記憶することにより、列車の走行状態や車輪の磨耗状態を確認することができ、安全性を向上することができる。   Further, by storing the average speed obtained from the average speed of the train included in the ATC signal received for each track circuit and the speed detected by the signal from the speed generator for each track circuit, the running state of the train and the wheel The wear state can be confirmed, and safety can be improved.

前記のように構成した列車制御装置で列車１の速度を検出して列車の走行を制御するときの動作を説明する。   The operation when the train control device configured as described above detects the speed of the train 1 to control the traveling of the train will be described.

軌道回路１Ｔに列車１が進入して軌道回路１Ｔに接続されたＴＤ信号受信器４ａで列車１を検知すると、ＴＤ信号受信器４ａの列車検知部１０は軌道回路２Ｔに接続されたＴＤ信号送信器３ｂに列車検出信号を送る。軌道回路２Ｔに接続されたＴＤ信号送信器３ｂの軌道情報発生部６は、ＴＤ信号受信器４ａから列車検出信号が送られると、軌道回路１Ｔに列車１が進入したことを示す進入側軌道回路列車検出信号と、軌道回路１Ｔの軌道長Ｌ１とを有する軌道回路情報を発生してＴＤ信号生成部７に送る。ＴＤ信号生成部７は送られた軌道回路情報を含むＴＤ信号を生成して送信部８から軌道回路２Ｔに送信する。   When the train 1 enters the track circuit 1T and the train 1 is detected by the TD signal receiver 4a connected to the track circuit 1T, the train detection unit 10 of the TD signal receiver 4a transmits the TD signal connected to the track circuit 2T. A train detection signal is sent to the device 3b. The track information generator 6 of the TD signal transmitter 3b connected to the track circuit 2T, when a train detection signal is sent from the TD signal receiver 4a, indicates that the train 1 has entered the track circuit 1T. Track circuit information having the train detection signal and the track length L1 of the track circuit 1T is generated and sent to the TD signal generator 7.

The average speed Vm at the time when it has been calculated is calculated and sent to the ATC signal generator 15 of the ATC signal transmitter 5b.

ＡＴＣ信号送信器５ｂのＡＴＣ信号生成部１５はＴＤ信号受信器４から列車１が軌道回路１Ｔを走行していたときの平均速度Ｖｍが送られると、制御情報発生部１４で発生した制御情報と送られた平均速度Ｖｍ及び軌道回路２Ｔの軌道回路ＩＤ含むＡＴＣ信号を生成して送信部１６から軌道回路２Ｔに送信する。   When the average speed Vm when the train 1 is traveling on the track circuit 1T is sent from the TD signal receiver 4 to the ATC signal generator 15 of the ATC signal transmitter 5b, the control information generated by the control information generator 14 and The ATC signal including the sent average speed Vm and the track circuit ID of the track circuit 2T is generated and transmitted from the transmitter 16 to the track circuit 2T.

一方、列車１に搭載された車上装置２の速度検出部１９は、列車１が軌道回路を走行しているとき速度発電機２５から送られる信号により連続して列車１の速度Ｖｓを検出して平均速度演算部２０と速度補正部２１に送っている。平均速度演算部２０は、列車１の先頭車両が軌道回路１Ｔに進入して軌道回路１Ｔに接続されたＡＴＣ信号送信器５ａから軌道回路１Ｔに送信しているＡＴＣ信号を受信部１７で受信開始してから列車１の先頭車両が軌道回路２Ｔに進入して軌道回路２Ｔに送信するＡＴＣ信号を受信部１７で受信するまでの間の速度検出部１９から送られる速度Ｖｓの平均速度Ｖｓｍを演算してデータ記憶部２３に軌道回路１Ｔの軌道回路ＩＤとともに記憶させるとともに速度補正部１１に送る。車上装置の速度情報検知部１８は軌道回路２Ｔに送信されたＡＴＣ信号を受信部１７で受信すると、ＡＴＣ信号に含まれる列車１が軌道回路１Ｔを走行したときの平均速度Ｖｍを検出してデータ記憶部２３に軌道回路１Ｔの軌道回路ＩＤとともに記憶させるとともに速度補正部２１に送る。速度補正部２１は速度情報検知部１８で検出した軌道回路１Ｔの平均速度Ｖｍと平均速度演算部２０で演算した軌道回路１Ｔを列車１が走行したときの平均速度Ｖｓｍとの速度差ΔＶ＝（Ｖｍ−Ｖｓｍ）を演算し、演算した速度差ΔＶにより速度検出部１９で検出した速度Ｖｓを補正し、補正した速度Ｖ＝（Ｖｓ＋ΔＶ）を速度制御部２２に送る。速度制御部２２は速度補正部２１で補正した速度Ｖと受信部１７で受信したＡＴＣ信号に含まれる制限速度とを照査して、照査結果によりブレーキ装置等を制御して列車１の速度が制限速度になるように制御する。   On the other hand, the speed detector 19 of the on-board device 2 mounted on the train 1 continuously detects the speed Vs of the train 1 by a signal sent from the speed generator 25 when the train 1 is traveling on the track circuit. To the average speed calculation unit 20 and the speed correction unit 21. The average speed calculation unit 20 starts receiving the ATC signal transmitted to the track circuit 1T from the ATC signal transmitter 5a connected to the track circuit 1T when the leading vehicle of the train 1 enters the track circuit 1T. Then, the average speed Vsm of the speed Vs sent from the speed detector 19 is calculated from the time when the leading vehicle of the train 1 enters the track circuit 2T until the ATC signal transmitted to the track circuit 2T is received by the receiving unit 17. Then, it is stored in the data storage unit 23 together with the track circuit ID of the track circuit 1T and sent to the speed correction unit 11. When the speed information detector 18 of the on-board device receives the ATC signal transmitted to the track circuit 2T, the receiver 17 detects the average speed Vm when the train 1 included in the ATC signal travels the track circuit 1T. The data storage unit 23 stores the track circuit ID together with the track circuit ID of the track circuit 1T and sends it to the speed correction unit 21. The speed correction unit 21 has a speed difference ΔV = () between the average speed Vm of the track circuit 1T detected by the speed information detection unit 18 and the average speed Vsm when the train 1 travels on the track circuit 1T calculated by the average speed calculation unit 20. Vm−Vsm) is calculated, the speed Vs detected by the speed detector 19 is corrected by the calculated speed difference ΔV, and the corrected speed V = (Vs + ΔV) is sent to the speed controller 22. The speed control unit 22 checks the speed V corrected by the speed correction unit 21 and the speed limit included in the ATC signal received by the receiving unit 17, and controls the brake device and the like based on the result of verification to limit the speed of the train 1. Control to be speed.

このように各軌道回路を走行しているときの列車１の平均速度Ｖｍを地上に設けたＴＤ信号送信器４で求めて列車１に送信し、列車１の車上装置２は速度発電機２５からの信号により検出した速度の平均速度Ｖｓｍを求めて地上で算出した平均速度Ｖｍとの速度差ΔＶを算出して速度発電機２５からの信号により検出した速度を修正することにより、車輪の磨耗によって大きさが変化して速度発電機２５からの信号により検出した速度に誤差が生じても、その誤差を修正して列車１の速度を精度良く検出することができるとともに速度修正用の地上子を設けないですみ、設備費を低減することができる。   Thus, the average speed Vm of the train 1 when traveling on each track circuit is obtained by the TD signal transmitter 4 provided on the ground and transmitted to the train 1, and the on-board device 2 of the train 1 is the speed generator 25. Wear of the wheel by correcting the speed detected by the signal from the speed generator 25 by calculating the speed difference ΔV from the average speed Vm calculated on the ground by obtaining the average speed Vsm detected by the signal from Even if an error occurs in the speed detected by the signal from the speed generator 25 due to the change of the speed of the vehicle, the error can be corrected and the speed of the train 1 can be detected with high accuracy and the ground element for speed correction can be detected. Equipment costs can be reduced.

また、地上で求めた平均速度Ｖｍと車上装置２で算出した平均速度Ｖｓｍを各軌道回路ＩＤとともに車上装置２のデータ記憶部２３に記憶させるから、列車１の走行状態や車輪の磨耗状態を確認することができる。   Further, since the average speed Vm obtained on the ground and the average speed Vsm calculated by the onboard device 2 are stored in the data storage unit 23 of the onboard device 2 together with each track circuit ID, the running state of the train 1 and the worn state of the wheels. Can be confirmed.

前記説明では各軌道回路を利用して地上で求めた平均速度Ｖｍと車上装置２で算出した平均速度Ｖｓｍにより速度発電機２５からの信号により検出した速度を修正する場合について説明したが、速度発電機２５を使用せずに各軌道回路を利用して地上で求めた平均速度Ｖｍにより列車１の速度を制限速度以下に制御するようにしても良い。   In the above description, the case where the speed detected by the signal from the speed generator 25 is corrected by the average speed Vm obtained on the ground using each track circuit and the average speed Vsm calculated by the on-board device 2 has been described. You may make it control the speed of the train 1 below a speed limit by the average speed Vm calculated | required on the ground using each track circuit, without using the generator 25. FIG.
