Description

本発明は、列車のＡＴＣ、ＡＴＳ、ＡＴＯ等の列車自動運転用の列車速度を検出する列車速度検出装置に関する。   The present invention relates to a train speed detection device that detects a train speed for automatic train operation such as ATC, ATS, ATO of a train.

例えば、列車のＡＴＣ、ＡＴＳ、ＡＴＯ用の列車速度は、主電動機軸に設けられた２個の速度検出器ＴＧで検出するようにしている。この速度検出器ＴＧは駆動軸の１回転につき６０個のパルス信号が出力され、主電動機の回転方向は主電動機の２相分で速度検出して判断するようにしている。なお、列車の速度が５ｋｍ／ｈ以下では回転方向の情報は信頼性が落ちるので、信頼性が要求されるＡＴＣ速度に対しては、その検出された回転方向は採用していない。   For example, the train speeds for ATC, ATS, and ATO of the train are detected by two speed detectors TG provided on the main motor shaft. The speed detector TG outputs 60 pulse signals per rotation of the drive shaft, and the rotational direction of the main motor is determined by detecting the speed for two phases of the main motor. In addition, since the reliability of the rotational direction falls when the train speed is 5 km / h or less, the detected rotational direction is not adopted for the ATC speed that requires reliability.

ここで、専用軌道上を運行する列車などの移動体の位置と速度を、車輪の空転や滑走、あるいは車輪径の測定誤差の影響を受けずに正確に検出できるようにしたものがある（例えば、特許文献１参照）。
特開２００２−３７０７０号公報 Here, there is one that can accurately detect the position and speed of a moving body such as a train operating on a dedicated track without being affected by wheel slipping or sliding, or measurement error of wheel diameter (for example, , See Patent Document 1).
JP 2002-37070 A

しかし、列車の速度が５ｋｍ／ｈ以下で回転方向の情報が不正確であると、列車のＡＴＣ、ＡＴＳ、ＡＴＯ用の列車速度として使用するには信頼性が落ちるので、より信頼性を高めた列車速度検出装置が望まれている。   However, if the train speed is 5 km / h or less and the information on the direction of rotation is inaccurate, the reliability of using it as the train speed for ATC, ATS, and ATO of the train is reduced, so the reliability has been improved. A train speed detection device is desired.

本発明の目的は、より精度良く列車のＡＴＣ、ＡＴＳ、ＡＴＯ用の列車速度を検出できる列車速度検出装置を提供することである。   The objective of this invention is providing the train speed detection apparatus which can detect the train speed for ATC, ATS, and ATO of a train more accurately.

本発明の列車検出装置は、列車の編成内の主電動機を駆動制御する複数台のＶＶＶＦインバータを制御するとともに列車の速度を演算する速度演算手段を備えた複数台のＶＶＶＦインバータ制御装置と、各々のＶＶＶＦインバータ制御装置の前記速度演算手段が演算した速度の平均値を求めＡＴＣ、ＡＴＳ、ＡＴＯに出力する速度演算器とを備えたことを特徴とする。   The train detection device of the present invention controls a plurality of VVVF inverters that drive and control a main motor in a train formation, and includes a plurality of VVVF inverter control devices each provided with speed calculation means for calculating a train speed, And a speed calculator for obtaining an average value of speeds calculated by the speed calculation means of the VVVF inverter control device and outputting the average value to ATC, ATS, and ATO.

本発明によれば、各々のＶＶＶＦインバータ制御装置の速度演算手段が演算した速度の平均値を求めるので、より精度良く列車のＡＴＣ、ＡＴＳ、ＡＴＯ用の列車速度を検出できる。   According to the present invention, since the average value of the speeds calculated by the speed calculation means of each VVVF inverter control device is obtained, the train speeds for ATC, ATS, and ATO of the train can be detected with higher accuracy.

図１は本発明の実施の形態に係わる列車速度検出装置を搭載した列車の編成図である。列車の編成では主電動機を搭載した車両と主電動機を搭載しない車両とが混在して編成される。図１では列車編成のうち先頭部分の３つの車両１１を示しており、車両１１ａは主電動機を搭載していない車両であり、車両１１ｂ、１１ｃは主電動機を搭載している車両である。   FIG. 1 is a train diagram of a train equipped with a train speed detection device according to an embodiment of the present invention. In train formation, a vehicle equipped with a main motor and a vehicle not equipped with a main motor are mixed. FIG. 1 shows three vehicles 11 at the head of the train formation. The vehicle 11a is a vehicle not equipped with a main motor, and the vehicles 11b and 11c are vehicles equipped with a main motor.

先頭車両１１ａにはＡＴＣ、ＡＴＳ、ＡＴＯなどの列車自動運転装置１２が搭載されており、また、本発明の実施の形態に係わる列車速度検出装置における速度演算器１３が設けられている。一方、車両１１ｂ、１１ｃには、車輪１５の駆動軸を駆動するための図示省略の主電動機を搭載しており、主電動機はＶＶＶＦインバータ１４で駆動される。図１では車両１１ｂ、１１ｃの各々の車輪１５の駆動軸をそれぞれ駆動するための４台のＶＶＶＦインバータ１４が設けられている。   The leading vehicle 11a is equipped with an automatic train operation device 12 such as ATC, ATS, or ATO, and is provided with a speed calculator 13 in the train speed detection device according to the embodiment of the present invention. On the other hand, a main motor (not shown) for driving the drive shaft of the wheel 15 is mounted on the vehicles 11b and 11c, and the main motor is driven by the VVVF inverter 14. In FIG. 1, four VVVF inverters 14 for driving the drive shafts of the wheels 15 of the vehicles 11b and 11c are provided.

ＶＶＶＦインバータ１４は、ＶＶＶＦインバータ制御装置１６により制御される。図１では１つの車両１１ｂ、１１ｃにそれぞれ１台のＶＶＶＦインバータ制御装置１６を設けた場合を示している。ＶＶＶＦインバータ制御装置１６は列車の速度を演算する速度演算手段を備えており、この速度演算手段により列車の速度を演算して列車の速度を求めるようにしている。   The VVVF inverter 14 is controlled by the VVVF inverter control device 16. FIG. 1 shows a case where one VVVF inverter control device 16 is provided in each of the vehicles 11b and 11c. The VVVF inverter control device 16 includes speed calculation means for calculating the speed of the train, and the speed of the train is calculated by the speed calculation means so as to obtain the train speed.

列車１１ａ〜１１ｃには信号伝送線１７が付設されており、各車両毎に設けられたＶＶＶＦインバータ制御装置１６の速度演算手段で演算された列車の速度は、信号伝送線１７を介してＡＴＣ、ＡＴＳ、ＡＴＯなどの列車自動運転装置１２に送信される。   A signal transmission line 17 is attached to the trains 11a to 11c, and the train speed calculated by the speed calculation means of the VVVF inverter control device 16 provided for each vehicle is ATC, It is transmitted to train automatic operation devices 12 such as ATS and ATO.

速度演算器１３は、各々のＶＶＶＦインバータ制御装置１６の速度演算手段が演算した速度の平均値を求め、ＡＴＣ、ＡＴＳ、ＡＴＯなどの列車自動運転装置１２に出力する。列車自動運転装置１２は複数台のＶＶＶＦインバータ制御装置１６で演算された列車の速度の平均値を列車の速度として使用するので、信頼性が向上する。   The speed calculator 13 obtains an average value of the speeds calculated by the speed calculation means of each VVVF inverter control device 16 and outputs the average value to the train automatic operation device 12 such as ATC, ATS, or ATO. Since the train automatic operation device 12 uses the average value of the train speed calculated by the plurality of VVVF inverter control devices 16 as the train speed, the reliability is improved.

図２は、本発明の実施の形態に係わる列車速度検出装置の一例を示すブロック構成図である。図２に示すように、車輪の駆動軸を駆動する主電動機１８はＶＶＶＦインバータ１４で駆動される。ＶＶＶＦインバータ１４はＶＶＶＦインバータ制御装置１６で制御され、１台のＶＶＶＦインバータ制御装置１６で４台のＶＶＶＦインバータ１４を駆動制御する場合を示している。   FIG. 2 is a block configuration diagram showing an example of a train speed detection device according to the embodiment of the present invention. As shown in FIG. 2, the main motor 18 that drives the drive shaft of the wheel is driven by the VVVF inverter 14. The VVVF inverter 14 is controlled by the VVVF inverter control device 16, and four VVVF inverters 14 are driven and controlled by one VVVF inverter control device 16.

ＶＶＶＦインバータ制御装置１６の速度演算手段１９は、例えば、トルク指令に基づき列車の速度を推定演算して列車の速度を求める。各々のＶＶＶＦインバータ制御装置１６の速度演算手段１９で演算された列車の速度は、速度演算器１３に送信される。速度演算器１３は、各々のＶＶＶＦインバータ制御装置１６から入力した速度の平均値を求め列車自動運転装置１２に出力する。   For example, the speed calculation means 19 of the VVVF inverter control device 16 estimates and calculates the train speed based on the torque command to obtain the train speed. The train speed calculated by the speed calculation means 19 of each VVVF inverter control device 16 is transmitted to the speed calculator 13. The speed calculator 13 calculates the average value of the speeds input from the respective VVVF inverter control devices 16 and outputs the average value to the train automatic operation device 12.

速度演算器１３は、複数台のＶＶＶＦインバータ制御装置１６で演算された列車の速度を入力し、それらの平均値を求めて列車の速度として列車自動運転装置１２に出力する。列車自動運転装置１２は、複数台のＶＶＶＦインバータ制御装置１６で演算された列車の速度の平均値を列車の速度として使用するので、列車の速度の信頼性が向上する。例えば、主電動機１８を搭載した車両（Ｍ車）が１２両ある場合には、１２個の速度の検出が可能であるので、これらを加算平均すれば信頼性は向上する。   The speed calculator 13 inputs the train speed calculated by the plurality of VVVF inverter control devices 16, obtains an average value thereof, and outputs it to the train automatic operation device 12 as the train speed. Since the train automatic operation device 12 uses the average value of the train speed calculated by the plurality of VVVF inverter control devices 16 as the train speed, the reliability of the train speed is improved. For example, when there are twelve vehicles (M cars) equipped with the main motor 18, twelve speeds can be detected. If these are averaged, the reliability is improved.

以上の説明では、１車両の４台のＶＶＶＦインバータ１４に対し、１台のＶＶＶＦインバータ制御装置１９を設けた場合について説明したが、図３に示すように、ＶＶＶＦインバータ１４毎にＶＶＶＦインバータ制御装置１６を設けるようにしてもよい。ＶＶＶＦインバータ１４毎にＶＶＶＦインバータ制御装置１６を設けた個別制御方式の場合には、主電動機１８を搭載した車両（Ｍ車）が１２両ある場合には、４８個の速度の検出が可能であるので、これらを加算平均すればさらに信頼性は向上する。   In the above description, a case where one VVVF inverter control device 19 is provided for four VVVF inverters 14 in one vehicle has been described. However, as shown in FIG. 3, a VVVF inverter control device is provided for each VVVF inverter 14. 16 may be provided. In the case of the individual control method in which the VVVF inverter control device 16 is provided for each VVVF inverter 14, when there are 12 vehicles (M cars) equipped with the main motor 18, it is possible to detect 48 speeds. Therefore, if these are added and averaged, the reliability is further improved.

また、以上の説明では、速度演算器１３では、各々のＶＶＶＦインバータ制御装置１６の速度制御手段１９で演算した速度の平均値を求めるようにしたが、列車の力行運転時には各々のＶＶＶＦインバータ制御装置１４の速度演算手段１９が演算した速度のうち低速側の速度の平均値を演算し、列車の回生運転時には各々のＶＶＶＦインバータ制御装置１６の速度演算手段１９が演算した速度のうち高速側の速度の平均値を演算するようにしてもよい。   Further, in the above description, the speed calculator 13 calculates the average value of the speeds calculated by the speed control means 19 of each VVVF inverter control device 16, but each VVVF inverter control device during the power running operation of the train. Of the speeds calculated by the speed calculation means 19 of the fourteen speeds is calculated, and the speed on the high speed side of the speeds calculated by the speed calculation means 19 of each VVVF inverter control device 16 during the regenerative operation of the train. You may make it calculate the average value of.

力行運転時には車輪が空転することがあり、車輪が空転したときは実際の速度より高速と演算してしまう。そこで、力行運転時のときは信頼性の低い高速側の速度は排除して低速側の速度の平均値を演算しこれを列車の速度とする。これにより、列車の速度の信頼性が向上する。一方、回生運転時には車輪が滑走することがあり、車輪が滑走すると実際の速度より低速と演算してしまう。そこで、回生運転時のときは信頼性の低い低速側の速度は排除して高速側の速度の平均値を演算し、これを列車の速度とする。これにより、列車の速度の信頼性が向上する。   During power running, the wheel may idle, and when the wheel idles, the speed is calculated to be higher than the actual speed. Therefore, during power running, the high speed side speed with low reliability is excluded and the average value of the low speed side speed is calculated and used as the train speed. Thereby, the reliability of the speed of a train improves. On the other hand, during regenerative operation, the wheel may slide, and when the wheel slides, the speed is calculated to be lower than the actual speed. Therefore, during regenerative operation, the low-speed speed with low reliability is excluded and the average value of the high-speed speed is calculated, and this is used as the train speed. Thereby, the reliability of the speed of a train improves.

また、ＶＶＶＦインバータ制御装置１６は速度演算手段１９で演算した速度を速度演算器１３に送信するようにしたが、速度演算手段１９で演算した速度に加え、速度演算手段１９での速度演算異常情報や空転滑走情報を速度演算器１３に送信することも可能である。   The VVVF inverter control device 16 transmits the speed calculated by the speed calculation means 19 to the speed calculator 13, but in addition to the speed calculated by the speed calculation means 19, the speed calculation abnormality information in the speed calculation means 19 is displayed. It is also possible to transmit idle running information to the speed calculator 13.

速度演算器１３は、速度演算異常情報や空転滑走情報を受信したときは、速度演算異常の可能性や空転滑走の可能性を判断し、速度演算異常や空転滑走が発生していると判断したときは、ＶＶＶＦインバータ制御装置１６の速度演算手段１９から送信されてきた速度を、列車の速度の演算に用いないようにする。これにより、速度演算器１３での列車の速度の演算の信頼性を向上させる。   When the speed calculator 13 receives the speed calculation abnormality information and the idling information, the speed calculator 13 determines the possibility of the speed calculation anomaly and the possibility of idling, and determines that the speed calculation abnormality and idling have occurred. In some cases, the speed transmitted from the speed calculation means 19 of the VVVF inverter control device 16 is not used for the calculation of the train speed. Thereby, the reliability of the calculation of the train speed by the speed calculator 13 is improved.

次に、図４に示すように、主電動機１８として永久磁石を用いた永久磁石同期電動機ＰＭＳＭとし、永久磁石同期電動機ＰＭＳＭの端子電圧を検出する電圧検出器２０を設け、ＶＶＶＦインバータ制御装置１６の速度演算手段１９は、電圧検出器２０で検出された永久磁石同期電動機ＰＭＳＭの端子電圧に基づき速度を演算するようにしてもよい。   Next, as shown in FIG. 4, a permanent magnet synchronous motor PMSM using a permanent magnet as the main motor 18 is provided, and a voltage detector 20 for detecting a terminal voltage of the permanent magnet synchronous motor PMSM is provided, and the VVVF inverter control device 16 The speed calculation means 19 may calculate the speed based on the terminal voltage of the permanent magnet synchronous motor PMSM detected by the voltage detector 20.

この場合、電圧検出器２０は、ＶＶＶＦインバータ１４と主電動機１８との間に接続される負荷接触器２１より主電動機１８側に設ける。これは、負荷接触器２１が遮断した場合であっても主電動機１８の速度を検出可能とするためである。電圧検出器２０は、主電動機１８（永久磁石同期電動機ＰＭＳＭ）の端子電圧の少なくとも２相分を検出するように、２台の電圧検出器２０が設けられている。ＶＶＶＦインバータ制御装置１６の速度演算手段１９は、電圧検出器２０で検出した永久磁石同期電動機ＰＭＳＭの端子電圧の少なくとも２相分に基づいて、符号付きの速度を演算する。   In this case, the voltage detector 20 is provided closer to the main motor 18 than the load contactor 21 connected between the VVVF inverter 14 and the main motor 18. This is because the speed of the main motor 18 can be detected even when the load contactor 21 is interrupted. The voltage detector 20 is provided with two voltage detectors 20 so as to detect at least two phases of the terminal voltage of the main motor 18 (permanent magnet synchronous motor PMSM). The speed calculation means 19 of the VVVF inverter control device 16 calculates a signed speed based on at least two phases of the terminal voltage of the permanent magnet synchronous motor PMSM detected by the voltage detector 20.

なお、電圧検出器２０は１台とし、１台の電圧検出器２０で永久磁石同期電動機ＰＭＳＭの端子電圧の１相分を検出し、速度演算手段１９は列車の進行方向が不明である場合には、ＶＶＶＦインバータ制御装置１６が所定のインバータを０トルクで起動させたときの符号に基づいて符号付きの速度を求めるようにしてもよい。つまり、速度演算手段１９は、１台の電圧検出器２０で検出した永久磁石同期電動機ＰＭＳＭの端子電圧の１相分及びＶＶＶＦインバータ制御装置１６が所定のインバータを０トルクで起動させたときの符号に基づいて、符号付きの速度を求める。   The voltage detector 20 is one unit, and one voltage detector 20 detects one phase of the terminal voltage of the permanent magnet synchronous motor PMSM, and the speed calculation means 19 is used when the traveling direction of the train is unknown. The VVVF inverter control device 16 may obtain a signed speed based on a sign when a predetermined inverter is activated with zero torque. That is, the speed calculation means 19 is for one phase of the terminal voltage of the permanent magnet synchronous motor PMSM detected by one voltage detector 20 and the sign when the VVVF inverter control device 16 starts a predetermined inverter with 0 torque. Based on the above, the signed speed is obtained.

また、電圧検出器２０で検出した永久磁石同期電動機ＰＭＳＭの端子電圧から基本波を抽出するフィルタを設け、フィルタで抽出された永久磁石同期電動機ＰＭＳＭの端子電圧の基本波を速度演算手段１９に入力するようにしてもよい。これにより、永久磁石同期電動機ＰＭＳＭがＰＷＭ制御で運転されている場合であっても、その周波数を正確に把握できる
ここで、永久磁石同期電動機ＰＭＳＭは速度検出器ＴＧと原理的には変わらないが、その誘起電圧を電圧検出器２０により検出し、速度演算手段１９で列車の速度を演算する。つまり、速度検出器ＴＧを電圧検出器２０及び速度演算手段１９に置き換える。主電動機１８（永久磁石同期電動機ＰＭＳＭ）の誘起電圧は、電気角に対して１周期となる。いま、主電動機１８（永久磁石同期電動機ＰＭＳＭ）と駆動軸とのギア比を３、主電動機１８の極対数を３（極数６）とすると、速度検出器ＴＧより６〜７倍の精度劣化になるが、少なくとも６〜７台以上の複数台のＶＶＶＦインバータ制御装置１６の速度演算手段１９で演算した速度を加算平均すれば、その信頼性は現状の速度検出器ＴＧの信頼性を上回る。 Further, a filter for extracting a fundamental wave from the terminal voltage of the permanent magnet synchronous motor PMSM detected by the voltage detector 20 is provided, and the fundamental wave of the terminal voltage of the permanent magnet synchronous motor PMSM extracted by the filter is input to the speed calculation means 19. You may make it do. Thereby, even when the permanent magnet synchronous motor PMSM is operated by PWM control, the frequency can be accurately grasped. Here, the permanent magnet synchronous motor PMSM is not different in principle from the speed detector TG. The induced voltage is detected by the voltage detector 20, and the speed calculation means 19 calculates the train speed. That is, the speed detector TG is replaced with the voltage detector 20 and the speed calculation means 19. The induced voltage of the main motor 18 (permanent magnet synchronous motor PMSM) is one cycle with respect to the electrical angle. If the gear ratio between the main motor 18 (permanent magnet synchronous motor PMSM) and the drive shaft is 3, and the number of pole pairs of the main motor 18 is 3 (number of poles 6), the accuracy will be 6 to 7 times that of the speed detector TG. However, if the speeds calculated by the speed calculation means 19 of at least 6 to 7 VVVF inverter control devices 16 are added and averaged, the reliability exceeds the reliability of the current speed detector TG.

なお、ＶＶＶＦインバータ１４の動作中は、永久磁石同期電動機ＰＭＳＭの誘起電圧を電圧検出器２０で検出することはできないが、その場合は、永久磁石同期電動機ＰＭＳＭは同期電動機であるため、ＶＶＶＦインバータ１４の動作中にインバータ制御装置１６が推定する回転数で代用しても速度の精度の劣化は生じない。また、以上の説明では、速度演算手段１９は、ＶＶＶＦインバータ制御装置１６内に設けたが、ＶＶＶＦインバータ制御装置１６とは独立に設けるようにしてもよい。   During the operation of the VVVF inverter 14, the induced voltage of the permanent magnet synchronous motor PMSM cannot be detected by the voltage detector 20. In this case, since the permanent magnet synchronous motor PMSM is a synchronous motor, the VVVF inverter 14 Even if the rotation speed estimated by the inverter control device 16 is substituted during the operation, speed accuracy does not deteriorate. In the above description, the speed calculation means 19 is provided in the VVVF inverter control device 16, but may be provided independently of the VVVF inverter control device 16.

発明の実施の形態によれば、複数台のＶＶＶＦインバータ制御装置１６で演算された列車の速度の平均値を列車の速度として使用するので、信頼性が向上する。また、力行運転時のときは信頼性の低い高速側の速度は排除して低速側の速度の平均値を演算し、回生運転時のときは信頼性の低い低速側の速度は排除して高速側の速度の平均値を演算するので、列車の速度の信頼性がさらに向上する。   According to the embodiment of the invention, since the average value of the train speed calculated by the plurality of VVVF inverter control devices 16 is used as the train speed, the reliability is improved. Also, during power running operation, the high speed side with low reliability is excluded and the average value of the low speed side is calculated, and during regenerative operation, the low speed side with low reliability is excluded and high speed is calculated. Since the average value of the side speed is calculated, the reliability of the train speed is further improved.

さらに、速度演算器１３は、速度演算異常情報や空転滑走情報を受信したときは、ＶＶＶＦインバータ制御装置１６の速度演算手段１９から送信されてきた速度を列車の速度の演算に用いないようにすることができるので、速度演算器１３での列車の速度の演算の信頼性を向上できる。   Furthermore, when the speed calculator 13 receives the speed calculation abnormality information or the idling information, the speed calculator 13 does not use the speed transmitted from the speed calculation means 19 of the VVVF inverter control device 16 for calculating the train speed. Therefore, the reliability of the calculation of the train speed by the speed calculator 13 can be improved.
