Description

流転検知装置、列車制御システムおよび流転検知方法Current detection device, train control system, and current detection method
　本発明は、列車に搭載される流転検知装置、列車制御システムおよび流転検知方法に関する。 The present invention relates to a flow transition detection device, a train control system, and a flow transition detection method mounted on a train.
　列車に搭載される車上制御装置は、列車の運用中、列車の位置を示す位置情報を地上装置へ送信する。運用されていない列車では車上制御装置の電源はオフであるため、車上制御装置は、位置情報を地上装置へ送信しない。そのため、運用されていない列車が流転した場合、地上装置は流転した列車の位置を把握できず、流転した列車が原因で事故が発生してしまう可能性がある。運用されていない列車の位置を把握するためには、列車が常に車上制御装置を動作させ、位置情報を地上装置に送信する必要がある。しかしながら、運用されていない列車で車上制御装置を常に動作させておくことは、省エネルギーの観点で好ましくない。 The on-board control device mounted on the train transmits position information indicating the position of the train to the ground device during operation of the train. Since the power of the on-board controller is off in a train that is not in operation, the on-board controller does not transmit position information to the ground device. Therefore, when a train that is not in use is turned over, the ground device cannot grasp the position of the turned over train, and an accident may occur due to the overturned train. In order to grasp the position of a train that is not in operation, it is necessary for the train to always operate the on-board control device and transmit the position information to the ground device. However, it is not preferable from the viewpoint of energy saving that the on-board controller is always operated on a train that is not in operation.
　特許文献１には、車上制御装置を停止している滞泊中の列車において、無線機が、センサで計測された情報を地上保安制御部へ送信し、地上保安制御部が、取得したセンサの情報に基づいて、滞泊中の列車が流転したか否かを判断する技術が開示されている。特許文献１に記載の車両制御システムにおいて、滞泊中の列車は、センサおよび無線機を動作させつつ、車上制御装置を停止させていることで、消費電力の増加を抑えている。 In Patent Document 1, in a train that is staying at a stop where the on-board controller is stopped, the radio transmits the information measured by the sensor to the ground security control unit, and the ground security control unit acquires the sensor. Based on the above information, a technique for determining whether or not a train that has been staying has swung is disclosed. In the vehicle control system described in Patent Document 1, a train that is staying at a stop suppresses an increase in power consumption by stopping the on-board control device while operating the sensor and the wireless device.
特開２０１６－１３７７３１号公報JP 2016-137731 A
　しかしながら、特許文献１に記載の車両制御システムでは、地上保安制御部は、列車が流転したと判断した場合、運用中の他の列車に対して列車防護を実施して停止させることができるが、車上制御装置が停止中に流転した列車に対して動作を制御するような列車防護を実施できない、という問題があった。 However, in the vehicle control system described in Patent Document 1, when the ground security control unit determines that the train has swung, it can be stopped by performing train protection on other trains in operation. There was a problem in that it was not possible to implement train protection that would control the operation of a train that was swept while the on-board controller was stopped.
　本発明は、上記に鑑みてなされたものであって、消費電力の増加を抑えつつ、搭載される列車が流転した場合に列車防護を実施可能な流転検知装置を得ることを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to provide a flow detection device capable of protecting a train when an on-board train flows while suppressing an increase in power consumption.
　上述した課題を解決し、目的を達成するために、本発明は、列車に搭載される流転検知装置である。流転検知装置は、列車の動作を制御する車上制御装置が稼働していない列車の運用停止中において、列車の移動を検知するセンサと、センサの検知結果に基づいて列車が流転したか否かを判定し、列車が流転したと判定した場合、列車防護を実施する流転検知部と、を備えることを特徴とする。 In order to solve the above-described problems and achieve the object, the present invention is a flow-transfer detection device mounted on a train. The current detection device is a sensor that detects the movement of the train and whether the train has been turned on or off based on the detection result of the train while the on-board control device that controls the operation of the train is not operating. And when the train is determined to have flowed, the vehicle has a flow detection unit that performs train protection.
　本発明によれば、流転検知装置は、消費電力の増加を抑えつつ、搭載される列車が流転した場合に列車防護を実施できる、という効果を奏する。 According to the present invention, the current detection device has an effect that train protection can be carried out when a mounted train is turned while suppressing an increase in power consumption.

　以下に、本発明の実施の形態にかかる流転検知装置、列車制御システムおよび流転検知方法を図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a flow change detection device, a train control system, and a flow change detection method according to an embodiment of the present invention will be described in detail based on the drawings. Note that the present invention is not limited to the embodiments.
実施の形態１．
　図１は、本発明の実施の形態１にかかる列車制御システム４の構成例を示す図である。列車制御システム４は、列車１と、無線装置２と、拠点装置３と、を備える。 Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a configuration example of a train control system 4 according to the first embodiment of the present invention. The train control system 4 includes a train 1, a wireless device 2, and a base device 3.
　列車１は、運用中、定期的に無線装置２を介して拠点装置３に自列車の位置情報を送信し、無線装置２を介して拠点装置３から受信した制御指令に従って走行する。また、列車１は、運用停止中、例えば、滞泊または留置されている状態において、自列車の流転を検知した場合、列車防護を実施する。流転とは、停止中の列車が、線路の勾配などが原因で、自列車の動力によらずに動いてしまうことである。列車防護とは、列車の停止を必要とする障害が発生した場合において、列車に危険を知らせるとともに、列車を安全に停止させることである。なお、本実施の形態では、列車１の編成車両の数は限定されない。列車１には、車両が１つの場合、すなわち１つの車両が単行で運用される場合が含まれる。 During operation, the train 1 periodically transmits its own train position information to the base device 3 via the wireless device 2 and travels according to the control command received from the base device 3 via the wireless device 2. Moreover, the train 1 implements train protection when the operation of the train 1 is detected while the operation is stopped, for example, in a state where the train 1 is detained or detained. Current turning means that a stopped train moves regardless of the power of its own train due to the slope of the track. Train protection means notifying the train of danger and stopping the train safely when a failure that requires the train to stop occurs. In the present embodiment, the number of trains for train 1 is not limited. The train 1 includes a case where there is one vehicle, that is, a case where one vehicle is operated in a single line.
　無線装置２は、地上に設置され、列車１と拠点装置３との間の無線通信を中継する。無線装置２は、列車１から受信した位置情報などの信号を拠点装置３へ送信し、拠点装置３から受信した制御指令などの信号を列車１へ送信する。なお、図１では、無線装置２が１つであるが、一例であり、１つの拠点装置３に対して２以上の無線装置２が接続されていてもよい。 The wireless device 2 is installed on the ground and relays wireless communication between the train 1 and the base device 3. The wireless device 2 transmits a signal such as position information received from the train 1 to the base device 3, and transmits a signal such as a control command received from the base device 3 to the train 1. In FIG. 1, there is one wireless device 2, but this is an example, and two or more wireless devices 2 may be connected to one base device 3.
　拠点装置３は、地上に設置された地上装置である。拠点装置３は、列車１から位置情報を取得し、列車１の進路など、列車１の運行を制御する。また、拠点装置３は、自装置の管轄内に複数の列車が在線している場合、列車同士の間隔を制御する。 The base device 3 is a ground device installed on the ground. The base device 3 acquires position information from the train 1 and controls the operation of the train 1 such as the course of the train 1. In addition, the base device 3 controls the interval between trains when a plurality of trains are present within the jurisdiction of the own device.
　列車１の構成について説明する。図２は、実施の形態１にかかる列車１の構成例を示すブロック図である。列車１は、車上制御装置１１と、ブレーキ１２と、流転検知装置１３と、を備える。図２に示す列車１では、本実施の形態において流転を検知する動作、および流転を検知した後の列車防護に関係する構成要素を示しており、一般的な構成要素については記載を省略している。車上制御装置１１は、列車１の動作を制御し、列車１の走行および停止を制御する。ブレーキ１２は、車上制御装置１１の制御により、列車１を減速または停止させる。 The configuration of the train 1 will be described. FIG. 2 is a block diagram illustrating a configuration example of the train 1 according to the first embodiment. The train 1 includes an on-board control device 11, a brake 12, and a flow-transfer detection device 13. In the train 1 shown in FIG. 2, the components related to the operation for detecting the advection and the train protection after the advection are detected in the present embodiment are shown, and the description of the general components is omitted. Yes. The on-board controller 11 controls the operation of the train 1 and controls the running and stopping of the train 1. The brake 12 decelerates or stops the train 1 under the control of the on-board controller 11.
　流転検知装置１３は、列車１の運用停止中において列車１の流転を検知する。列車１では、列車１の運用中、車上制御装置１１およびブレーキ１２が稼働し、流転検知装置１３は稼働しない。また、列車１では、列車１の運用停止中、流転検知装置１３が稼働し、車上制御装置１１およびブレーキ１２は稼働しない。列車１は、このように各構成要素が稼働することにより、運用停止中に車上制御装置１１が稼働する場合と比較して、運用停止中の消費電力の増加を抑えることができる。ただし、流転検知装置１３は、列車１の運用停止中において列車防護を実施する場合、車上制御装置１１を起動させ、車上制御装置１１が列車１を制御可能な状態にすることができる。流転検知装置１３は、流転検知部１４と、無線通信部１５と、バッテリー１６と、加速度センサ１７と、地磁気センサ１８と、ジャイロセンサ１９と、傾斜センサ２０と、ＧＰＳ（Global　Positioning　System）受信機２１と、を備える。なお、加速度センサ１７、地磁気センサ１８、ジャイロセンサ１９、傾斜センサ２０、およびＧＰＳ受信機２１を区別しない場合、これらをまとめて、または各々をセンサと称することがある。センサは、車上制御装置１１が稼働していない列車１の運用停止中において、列車１の移動を検知する。 The current transfer detection device 13 detects the current transfer of the train 1 while the operation of the train 1 is stopped. In the train 1, during operation of the train 1, the on-board control device 11 and the brake 12 are operated, and the flow transition detection device 13 is not operated. Further, in the train 1, while the operation of the train 1 is stopped, the advection detection device 13 operates, and the on-board control device 11 and the brake 12 do not operate. By operating each component in this manner, the train 1 can suppress an increase in power consumption during operation stop compared to the case where the on-board control device 11 operates during operation stop. However, when implementing the train protection while the operation of the train 1 is stopped, the current detection device 13 can activate the on-board control device 11 so that the on-board control device 11 can control the train 1. The flow detection device 13 includes a flow detection unit 14, a wireless communication unit 15, a battery 16, an acceleration sensor 17, a geomagnetic sensor 18, a gyro sensor 19, a tilt sensor 20, and a GPS (Global Positioning System) receiver. 21. In addition, when not distinguishing the acceleration sensor 17, the geomagnetic sensor 18, the gyro sensor 19, the inclination sensor 20, and the GPS receiver 21, these may be put together or each may be called a sensor. The sensor detects the movement of the train 1 while the operation of the train 1 where the on-board controller 11 is not operating is stopped.
　流転検知部１４は、加速度センサ１７、地磁気センサ１８、ジャイロセンサ１９、傾斜センサ２０、およびＧＰＳ受信機２１の各センサの検知結果に基づいて、列車１が流転したか否かを判定する。具体的には、流転検知部１４は、列車１の運用停止中において各センサの検知結果が列車１の移動を示すものであった場合、列車１が流転したと判定する。流転検知部１４は、列車１が流転したと判定した場合、列車防護を実施する。なお、流転検知部１４は、全てのセンサの検知結果を用いて列車１が流転したか否かを判定してもよいし、一部のセンサの検知結果を用いて列車１が流転したか否かを判定してもよい。また、流転検知装置１３は、図２に示すセンサの全てを備えず、図２に示すセンサの一部のみを備えてもよい。この場合、流転検知部１４は、流転検知装置１３が備える１つ以上のセンサの検知結果を用いて列車１が流転したか否かを判定する。 The current detection unit 14 determines whether the train 1 has been turned based on the detection results of the acceleration sensor 17, the geomagnetic sensor 18, the gyro sensor 19, the tilt sensor 20, and the GPS receiver 21. Specifically, the advection detection unit 14 determines that the train 1 has abated when the detection result of each sensor indicates the movement of the train 1 while the operation of the train 1 is stopped. When the current detection unit 14 determines that the train 1 has been changed, the current detection unit 14 performs train protection. In addition, the advection detection unit 14 may determine whether or not the train 1 has abended using the detection results of all sensors, or whether or not the train 1 has abated using the detection results of some sensors. It may be determined. In addition, the flow transition detection device 13 may not include all of the sensors illustrated in FIG. 2 but may include only a part of the sensors illustrated in FIG. In this case, the current-transfer detection unit 14 determines whether the train 1 has been current-transferred using detection results of one or more sensors included in the current-transfer detection device 13.
　無線通信部１５は、流転検知部１４において列車１が流転したと判定した場合、流転検知部１４の制御によって列車防護の信号の送信を行う。列車防護の信号とは、後述する列車１が流転したことを示す通知などである。また、無線通信部１５は、無線装置２を介して、拠点装置３から送信された信号を受信する。無線通信部１５は、例えば、特定小電力無線通信を行う無線装置である。 When the train commutation detector 14 determines that the train 1 has been swept up, the wireless communication unit 15 transmits a train protection signal under the control of the train turn detector 14. The train protection signal is a notification or the like indicating that a train 1 to be described later has been turned around. The wireless communication unit 15 receives a signal transmitted from the base device 3 via the wireless device 2. The wireless communication unit 15 is a wireless device that performs specific low-power wireless communication, for example.
　バッテリー１６は、流転検知部１４、無線通信部１５、加速度センサ１７、地磁気センサ１８、ジャイロセンサ１９、傾斜センサ２０、およびＧＰＳ受信機２１に電力を供給する。流転検知装置１３は、運用停止中に列車１の流転を検知する必要があるため、列車１が電車の場合、列車１の図示しないパンタグラフが下がっている状態、すなわち架線から電力が供給されていない状態でも動作しなければならない。そのため、流転検知装置１３、詳細にはバッテリー１６以外の流転検知装置１３の各構成要素は、バッテリー１６で駆動する。なお、図２では、バッテリー１６は流転検知部１４のみに接続され、流転検知部１４が各構成要素に電力を供給しているが、一例であり、バッテリー１６が各構成要素に直接電力を供給してもよい。また、バッテリー１６は、流転検知装置１３の外部にあってもよい。 The battery 16 supplies electric power to the flow transition detection unit 14, the wireless communication unit 15, the acceleration sensor 17, the geomagnetic sensor 18, the gyro sensor 19, the tilt sensor 20, and the GPS receiver 21. Since the current detection device 13 needs to detect the current flow of the train 1 during operation stop, when the train 1 is a train, the pantograph (not shown) of the train 1 is lowered, that is, power is not supplied from the overhead line. Must work even in the state. For this reason, each component of the flow transition detection device 13 other than the battery 16 in detail is driven by the battery 16. In FIG. 2, the battery 16 is connected only to the flow detection unit 14 and the flow detection unit 14 supplies power to each component. However, the battery 16 directly supplies power to each component. May be. Further, the battery 16 may be outside the flow-transfer detection device 13.
　加速度センサ１７は、列車１の加速度を検知し、列車１の加速度に基づいて列車１の移動を検知するセンサである。地磁気センサ１８は、列車１の周囲の地磁気を検知し、列車１の周囲の地磁気の変化に基づいて列車１の移動を検知するセンサである。ジャイロセンサ１９は、列車１の回転の変化、向きの変化など、すなわち列車１の姿勢の変化を検知し、列車１の姿勢の変化に基づいて列車１の移動を検知するセンサである。傾斜センサ２０は、列車１の傾きの変化を検知し、列車１の傾きの変化に基づいて列車１の移動を検知するセンサである。ＧＰＳ受信機２１は、列車１の位置を検知し、列車１の位置に基づいて列車１の移動を検知するセンサである。なお、図２に示すセンサは一例であり、流転検知装置１３は、さらに、図示しないデジタルカメラなどを備え、センサとして用いてもよい。また、流転検知装置１３は、図２に示すセンサのうち一部のセンサについては備えていなくてもよい。列車１は、流転検知装置１３が備える一部のセンサ、例えば、ＧＰＳ受信機２１などを運用中に使用してもよい。 The acceleration sensor 17 is a sensor that detects the acceleration of the train 1 and detects the movement of the train 1 based on the acceleration of the train 1. The geomagnetic sensor 18 is a sensor that detects the geomagnetism around the train 1 and detects the movement of the train 1 based on a change in geomagnetism around the train 1. The gyro sensor 19 is a sensor that detects a change in the rotation of the train 1, a change in direction, or the like, that is, a change in the posture of the train 1, and detects a movement of the train 1 based on a change in the posture of the train 1. The inclination sensor 20 is a sensor that detects a change in the inclination of the train 1 and detects the movement of the train 1 based on the change in the inclination of the train 1. The GPS receiver 21 is a sensor that detects the position of the train 1 and detects the movement of the train 1 based on the position of the train 1. The sensor shown in FIG. 2 is an example, and the flow transition detection device 13 may further include a digital camera (not shown) or the like, and may be used as a sensor. In addition, the flow transition detection device 13 may not include some of the sensors illustrated in FIG. The train 1 may use a part of sensors included in the flow diversion detection device 13, for example, the GPS receiver 21 during operation.
　拠点装置３の構成について説明する。図３は、実施の形態１にかかる拠点装置３の構成例を示すブロック図である。拠点装置３は、制御部３１と、通信部３２と、を備える。制御部３１は、列車１の運用中においては、列車１の位置情報などを用いて列車１の運行を制御する。また、制御部３１は、列車１の列車防護として列車１から流転したことを示す通知を取得した場合、拠点装置３の管轄内の他の列車に対して停止を指示する。通信部３２は、無線装置２から受信した列車１からの位置情報などの信号を制御部３１へ出力し、制御部３１から取得した制御指令などの信号を無線装置２へ送信する。通信部３２と無線装置２との間の通信は、有線通信であってもよいし、無線通信であってもよい。 The configuration of the base device 3 will be described. FIG. 3 is a block diagram of a configuration example of the base device 3 according to the first embodiment. The base device 3 includes a control unit 31 and a communication unit 32. The controller 31 controls the operation of the train 1 using the position information of the train 1 during operation of the train 1. Moreover, the control part 31 instruct | indicates a stop with respect to the other train in the jurisdiction of the base apparatus 3, when the notification which shows that it has swept from the train 1 as train protection of the train 1 is acquired. The communication unit 32 outputs a signal such as position information from the train 1 received from the wireless device 2 to the control unit 31, and transmits a signal such as a control command acquired from the control unit 31 to the wireless device 2. Communication between the communication unit 32 and the wireless device 2 may be wired communication or wireless communication.
　つづいて、列車制御システム４において、列車１の流転検知装置１３が、列車１の流転を検知する動作について説明する。図４は、実施の形態１にかかる流転検知装置１３が列車１の流転を検知する動作を示すフローチャートである。前述のように、流転検知装置１３は、列車１が運用停止中の滞泊または留置されている状態において動作を行う。流転検知装置１３において、流転検知部１４は、列車１が運用停止になると、各センサから検知結果を取得する（ステップＳ１）。 Next, the operation of the train control system 4 for detecting the flow transition of the train 1 in the train control system 4 will be described. FIG. 4 is a flowchart illustrating an operation in which the flow change detection device 13 according to the first embodiment detects the flow change of the train 1. As described above, the advection detection device 13 operates in a state where the train 1 is staying in a detained state or detained. In the flow change detection device 13, the flow change detection unit 14 acquires a detection result from each sensor when the operation of the train 1 is stopped (step S1).
　流転検知部１４は、各センサの検知結果に基づいて列車１が流転したか否かを判定する（ステップＳ２）。流転検知部１４は、例えば、各センサの検知結果と、各センサに対して列車１の移動を判定するために設定された各閾値とを比較する。流転検知部１４は、閾値以上のセンサの検知結果の数が予め設定した数以上有った場合、列車１が運用停止中に移動した、すなわち流転したと判定する。流転検知部１４は、閾値以上のセンサの検知結果の数が予め設定した数未満の場合、列車１が運用停止中に移動していない、すなわち流転していないと判定する。流転検知部１４は、複数のセンサの検知結果を用いることで、流転の誤検知を防止し、流転の検知精度を向上することができる。 The current flow detection unit 14 determines whether or not the train 1 has flowed based on the detection result of each sensor (step S2). For example, the flow transition detection unit 14 compares the detection result of each sensor with each threshold value set to determine the movement of the train 1 with respect to each sensor. When the number of detection results of sensors equal to or greater than the threshold is greater than or equal to the preset number, the current-transfer detection unit 14 determines that the train 1 has moved during operation stop, that is, has been current-transferred. When the number of detection results of the sensors equal to or greater than the threshold is less than the preset number, the current transfer detection unit 14 determines that the train 1 has not moved during operation stop, that is, has not been turned. By using the detection results of a plurality of sensors, the flow detection unit 14 can prevent erroneous detection of the flow and improve the detection accuracy of the flow.
　流転検知部１４は、列車１が流転していないと判定した場合（ステップＳ２：Ｎｏ）、処理を終了する。流転検知部１４は、列車１が流転したと判定した場合（ステップＳ２：Ｙｅｓ）、列車防護として、車上制御装置１１を起動し、車上制御装置１１に対してブレーキ１２を制御して列車１を停止させることを指示する（ステップＳ３）。車上制御装置１１は、流転検知部１４の制御によって起動し、流転検知部１４の指示によってブレーキ１２を制御して列車１を停止させる。このとき、車上制御装置１１は、流転検知部１４の制御によって起動すると、図示しないパンタグラフを上げて、架線から電力の供給を受ける。これにより、列車１は、車上制御装置１１の制御により、運用中と同様の動作を行うことが可能となる。なお、列車１では、流転検知部１４が、図示しないパンタグラフを上げて架線から電力の供給を受けるまでの制御を行い、その後に車上制御装置１１を起動してもよい。本実施の形態の流転検知装置１３は、第三軌条方式で電力の供給を受ける場合にも適用可能である。 If the current detection unit 14 determines that the train 1 is not current (Step S2: No), the process ends. When the current detection unit 14 determines that the train 1 has flowed (step S2: Yes), the on-board control device 11 is activated as train protection, and the train 12 is controlled by the brake 12 on the on-board control device 11. 1 is instructed to stop (step S3). The on-board controller 11 is activated by the control of the flow detection unit 14 and controls the brake 12 according to an instruction of the flow detection unit 14 to stop the train 1. At this time, when the on-vehicle control device 11 is activated by the control of the flow diversion detection unit 14, it raises a pantograph (not shown) and receives power supply from the overhead line. Thereby, the train 1 can perform the same operation as in operation by the control of the on-board controller 11. Note that, in the train 1, the advection detection unit 14 may perform control until a pantograph (not shown) is raised and power is supplied from the overhead line, and then the on-board controller 11 may be activated. The flow transition detection device 13 of the present embodiment is also applicable when receiving power supply by the third rail method.
　また、流転検知部１４は、列車防護として、列車１が流転したことを示す通知を無線通信部１５からブロードキャストで送信させる（ステップＳ４）。以下、列車１が流転したことを示す通知を、流転の通知と称することがある。流転検知部１４は、ステップＳ３およびステップＳ４の順番を入れ替えてもよいし、ステップＳ３およびステップＳ４を同時に実施してもよい。流転検知装置１３は、図４に示すフローチャートの動作を定期的に繰り返し実施する。 Moreover, the current detection unit 14 transmits, as a train protection, a notification indicating that the train 1 has been turned over by broadcasting from the wireless communication unit 15 (step S4). Hereinafter, a notification indicating that the train 1 has flowed may be referred to as a flow notification. The flow transition detection unit 14 may change the order of step S3 and step S4, or may simultaneously perform step S3 and step S4. The flow detection device 13 periodically repeats the operation of the flowchart shown in FIG.
　つぎに、列車１から、流転の通知を受信した拠点装置３の動作について説明する。図５は、実施の形態１にかかる列車制御システム４の他の構成例を示す図である。図５に示す列車制御システム４は、図１に示す列車制御システム４に、２つ目の無線装置２、および列車５，６を追加したものである。列車５，６は、拠点装置３の管轄内に在線する列車である。列車５，６は、列車１と同様の構成であってもよいし、拠点装置３からの制御指令によって走行可能であれば流転検知装置１３を備えていなくてもよい。列車１と同様、列車５，６には、車両が１つの場合、すなわち１つの車両が単行で運用される場合が含まれる。列車５，６をまとめて他の列車と称する。図６は、実施の形態１にかかる拠点装置３が列車１から流転の通知を受信したときの動作を示すフローチャートである。拠点装置３において、制御部３１は、無線装置２および通信部３２経由で列車１から流転の通知を受信する（ステップＳ１１）。制御部３１は、管轄内の他の列車に対して停止を指示する制御指令を生成する（ステップＳ１２）。制御部３１は、通信部３２および無線装置２経由で、生成した制御指令を管轄内の他の列車に送信する（ステップＳ１３）。拠点装置３から制御指令を受信した他の列車は、制御指令に従って停止する。 Next, the operation of the base apparatus 3 that has received the notice of the turnover from the train 1 will be described. FIG. 5 is a diagram illustrating another configuration example of the train control system 4 according to the first embodiment. A train control system 4 shown in FIG. 5 is obtained by adding a second wireless device 2 and trains 5 and 6 to the train control system 4 shown in FIG. The trains 5 and 6 are trains that exist within the jurisdiction of the base device 3. The trains 5 and 6 may have the same configuration as that of the train 1, and may not include the advection detection device 13 as long as the trains 5 and 6 can travel according to a control command from the base device 3. Similar to the train 1, the trains 5 and 6 include the case where there is one vehicle, that is, the case where one vehicle is operated in a single line. Trains 5 and 6 are collectively referred to as other trains. FIG. 6 is a flowchart illustrating an operation when the base device 3 according to the first embodiment receives a notice of current transfer from the train 1. In the base device 3, the control unit 31 receives a turnover notification from the train 1 via the wireless device 2 and the communication unit 32 (step S <b> 11). The control part 31 produces | generates the control command which instruct | indicates a stop with respect to the other train in jurisdiction (step S12). The control part 31 transmits the produced | generated control command to the other train in jurisdiction via the communication part 32 and the radio | wireless apparatus 2 (step S13). Other trains that have received the control command from the base unit 3 stop according to the control command.
　このように、列車１は、流転したと判定した場合、自列車を停止させ、他の列車を停止させる。これにより、列車１は、流転した場合に自列車が原因となる事故、例えば、列車同士の衝突を回避することができる。 Thus, when it is determined that the train 1 has flowed, the own train is stopped and the other trains are stopped. Thereby, the train 1 can avoid the accident which a self-train causes, for example, the collision of trains, when it turns.
　つづいて、流転検知装置１３のハードウェア構成について説明する。流転検知装置１３において、無線通信部１５は、特定小電力無線を行う通信装置である。バッテリー１６は、列車１の運用停止中において、バッテリー１６を除く流転検知装置１３の構成要素を駆動することが可能な小型のバッテリーである。加速度センサ１７、地磁気センサ１８、ジャイロセンサ１９、傾斜センサ２０、およびＧＰＳ受信機２１は、各センサで対象とする事象を計測する計測器である。流転検知部１４は、処理回路により実現される。処理回路は、メモリに格納されるプログラムを実行するプロセッサおよびメモリであってもよいし、専用のハードウェアであってもよい。 Next, the hardware configuration of the flow diversion detection device 13 will be described. In the flow transition detection device 13, the wireless communication unit 15 is a communication device that performs specific low-power wireless communication. The battery 16 is a small battery capable of driving the components of the current transfer detection device 13 excluding the battery 16 while the operation of the train 1 is stopped. The acceleration sensor 17, the geomagnetic sensor 18, the gyro sensor 19, the tilt sensor 20, and the GPS receiver 21 are measuring instruments that measure events that are targeted by each sensor. The flow transition detection unit 14 is realized by a processing circuit. The processing circuit may be a processor and a memory that execute a program stored in the memory, or may be dedicated hardware.
　図７は、実施の形態１にかかる流転検知装置１３が備える処理回路をプロセッサおよびメモリで構成する場合の例を示す図である。処理回路がプロセッサ９１およびメモリ９２で構成される場合、流転検知装置１３の処理回路の各機能は、ソフトウェア、ファームウェア、またはソフトウェアとファームウェアとの組み合わせにより実現される。ソフトウェアまたはファームウェアはプログラムとして記述され、メモリ９２に格納される。処理回路では、メモリ９２に記憶されたプログラムをプロセッサ９１が読み出して実行することにより、各機能を実現する。すなわち、処理回路は、流転検知装置１３の処理が結果的に実行されることになるプログラムを格納するためのメモリ９２を備える。また、これらのプログラムは、流転検知装置１３の手順および方法をコンピュータに実行させるものであるともいえる。 FIG. 7 is a diagram illustrating an example in which the processing circuit included in the flow transition detection device 13 according to the first embodiment is configured with a processor and a memory. When the processing circuit is configured by the processor 91 and the memory 92, each function of the processing circuit of the flow transition detection device 13 is realized by software, firmware, or a combination of software and firmware. Software or firmware is described as a program and stored in the memory 92. In the processing circuit, each function is realized by the processor 91 reading and executing the program stored in the memory 92. That is, the processing circuit includes a memory 92 for storing a program that results in the processing of the flow diversion detection device 13 being executed. Moreover, it can be said that these programs are what makes a computer perform the procedure and method of the flow-transfer detection apparatus 13. FIG.
　ここで、プロセッサ９１は、ＣＰＵ（Central　Processing　Unit）、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、またはＤＳＰ（Digital　Signal　Processor）などであってもよい。また、メモリ９２には、例えば、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、フラッシュメモリ、ＥＰＲＯＭ（Erasable　Programmable　ＲＯＭ）、ＥＥＰＲＯＭ（登録商標）（Electrically　ＥＰＲＯＭ）などの、不揮発性または揮発性の半導体メモリ、磁気ディスク、フレキシブルディスク、光ディスク、コンパクトディスク、ミニディスク、またはＤＶＤ（Digital　Versatile　Disc）などが該当する。 Here, the processor 91 may be a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor). The memory 92 is nonvolatile or volatile, such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable ROM), EEPROM (registered trademark) (Electrically EPROM), and the like. Such semiconductor memory, magnetic disk, flexible disk, optical disk, compact disk, mini disk, DVD (Digital Versatile Disc), and the like are applicable.
　図８は、実施の形態１にかかる流転検知装置１３が備える処理回路を専用のハードウェアで構成する場合の例を示す図である。処理回路が専用のハードウェアで構成される場合、図８に示す処理回路９３は、例えば、単一回路、複合回路、プログラム化したプロセッサ、並列プログラム化したプロセッサ、ＡＳＩＣ（Application　Specific　Integrated　Circuit）、ＦＰＧＡ（Field　Programmable　Gate　Array）、またはこれらを組み合わせたものが該当する。流転検知装置１３の各機能を機能別に処理回路９３で実現してもよいし、各機能をまとめて処理回路９３で実現してもよい。 FIG. 8 is a diagram illustrating an example of a case where the processing circuit included in the flow transition detection device 13 according to the first embodiment is configured with dedicated hardware. When the processing circuit is configured by dedicated hardware, the processing circuit 93 shown in FIG. 8 includes, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), An FPGA (Field Programmable Gate Array) or a combination of these is applicable. Each function of the flow transition detection device 13 may be realized by the processing circuit 93 for each function, or each function may be realized by the processing circuit 93 collectively.
　なお、流転検知装置１３の各機能について、一部を専用のハードウェアで実現し、一部をソフトウェアまたはファームウェアで実現するようにしてもよい。このように、処理回路は、専用のハードウェア、ソフトウェア、ファームウェア、またはこれらの組み合わせによって、上述の各機能を実現することができる。 It should be noted that a part of each function of the flow transition detection device 13 may be realized by dedicated hardware, and a part may be realized by software or firmware. As described above, the processing circuit can realize the above-described functions by dedicated hardware, software, firmware, or a combination thereof.
　つぎに、拠点装置３のハードウェア構成について説明する。拠点装置３において、通信部３２は、無線装置２との間で有線通信または無線通信を行う通信装置である。制御部３１は、処理回路により実現される。処理回路は、流転検知装置１３が備える処理回路と同様、図７または図８に示される構成となる。 Next, the hardware configuration of the base device 3 will be described. In the base device 3, the communication unit 32 is a communication device that performs wired communication or wireless communication with the wireless device 2. The control unit 31 is realized by a processing circuit. The processing circuit has the configuration shown in FIG. 7 or FIG. 8, as is the case with the processing circuit included in the flow diversion detection device 13.
　以上説明したように、本実施の形態によれば、列車１の運用停止中において、流転検知装置１３は、センサの検知結果に基づいて列車１が流転したと判定した場合、列車防護として、列車１を停止させるとともに、流転したことを拠点装置３に通知し、拠点装置３の制御によって他の列車を停止させることとした。列車１は、滞泊または留置している運用停止中は車上制御装置１１を停止しており、流転検知装置１３において列車１が流転したと判定した場合、流転検知装置１３が車上制御装置１１を起動して、停止する動作を行う。これにより、流転検知装置１３は、列車１における消費電力の増加を抑えつつ、搭載される列車１が流転した場合に、当該列車１に対して即座に列車防護を実施することができると共に、運用中の他の列車に対しても列車防護を実施することができる。 As described above, according to the present embodiment, when the operation of the train 1 is stopped, when the train motion detection device 13 determines that the train 1 has been trained based on the detection result of the sensor, 1 is stopped, the station apparatus 3 is notified that the current has been swung, and other trains are stopped under the control of the station apparatus 3. The train 1 stops the on-board control device 11 during suspension of staying or detained operation, and when the flow detection device 13 determines that the train 1 has flowed, the flow detection device 13 detects the on-board control device 13. 11 is started and stopped. As a result, the current detection device 13 can immediately implement train protection for the train 1 when the installed train 1 is turned over while suppressing an increase in power consumption in the train 1, and operation. Train protection can also be implemented for other trains inside.
　また、列車１は、拠点装置３など地上側の設備によらず、流転を判定することができる。そのため、列車１では、地上側において軌道回路、地上子などの設備が不要であることから、滞泊または留置の場所が限定されない。 In addition, the train 1 can determine the advection regardless of the ground side equipment such as the base unit 3. Therefore, in the train 1, facilities such as a track circuit and a ground element are not necessary on the ground side, and therefore, the place of staying or detention is not limited.
　なお、流転検知部１４は、列車１が流転したと判定した場合、列車１を即座に停止させず、拠点装置３からの制御指令を受信してから、列車１を停止させてもよい。この場合、拠点装置３の制御部３１は、図６のフローチャートに示すステップＳ１２の動作において、列車１を含む管轄内の全ての列車に対して停止を指示する制御指令を生成する。図９は、実施の形態１にかかる流転検知装置１３が列車１の流転を検知する他の動作を示すフローチャートである。流転検知部１４は、ステップＳ２：Ｙｅｓの場合、列車防護として、流転の通知を無線通信部１５からブロードキャストで送信させる（ステップＳ４）。流転検知部１４は、無線装置２および無線通信部１５を介して、拠点装置３から管轄内の全ての列車に対して停止を指示する制御指令を受信すると（ステップＳ５）、列車防護として、車上制御装置１１を起動し、車上制御装置１１に対してブレーキ１２を制御して列車１を停止させることを指示する（ステップＳ３）。この場合においても、流転検知装置１３または列車１において、列車１における消費電力の増加を抑えつつ、搭載される列車１が流転した場合に、当該列車１と運用中の他の列車に対して列車防護を実施することができる。 In addition, when it is determined that the train 1 has flowed, the current detection unit 14 may stop the train 1 after receiving the control command from the base device 3 without immediately stopping the train 1. In this case, the control unit 31 of the base device 3 generates a control command for instructing all trains in the jurisdiction including the train 1 to stop in the operation of step S12 shown in the flowchart of FIG. FIG. 9 is a flowchart illustrating another operation in which the flow change detection device 13 according to the first embodiment detects the flow change of the train 1. In the case of Step S2: Yes, the current-transfer detection unit 14 transmits a notification of current flow by broadcast from the wireless communication unit 15 as train protection (Step S4). When the current detection unit 14 receives a control command for instructing all the trains in the jurisdiction to stop from the base unit 3 via the wireless device 2 and the wireless communication unit 15 (step S5), The upper control device 11 is activated, and the vehicle control device 11 is instructed to control the brake 12 to stop the train 1 (step S3). Even in this case, in the flow-turning detection device 13 or the train 1, when the mounted train 1 is turned over while suppressing an increase in power consumption in the train 1, the train 1 and other trains in operation are trained. Protection can be implemented.
実施の形態２．
　実施の形態１では、拠点装置３の管轄内に在線している他の列車は、拠点装置３からの制御指令に基づいて停止していた。実施の形態２では、他の列車は、列車１から流転の通知を直接受信して停止する。実施の形態１と異なる部分について説明する。 Embodiment 2. FIG.
In the first embodiment, the other trains existing in the jurisdiction of the base device 3 are stopped based on the control command from the base device 3. In the second embodiment, the other trains directly receive a turnover notification from the train 1 and stop. A different part from Embodiment 1 is demonstrated.
　図１０は、実施の形態２にかかる列車制御システム４の構成例を示す図である。実施の形態２の列車１および拠点装置３の構成は、実施の形態１の列車１および拠点装置３の構成と同様である。図１０に示す列車制御システム４は、図５に示す実施の形態１の列車制御システム４に対して、列車５，６への信号の伝達経路が異なる。実施の形態２の流転検知装置１３は、実施の形態１と同様、図４に示す実施の形態１のフローチャートの動作を行う。ここで、列車１において、流転検知装置１３は、前述のように列車１が流転したと判定した場合（ステップＳ２：Ｙｅｓ）、流転の通知をブロードキャストで送信する（ステップＳ４）。すなわち、列車１の流転検知装置１３は、列車１が流転したと判定した場合、流転の通知を、拠点装置３の管轄内に在線し、拠点装置３が運行を管理する他の列車にブロードキャストで送信することになる。そのため、他の列車は、列車１から流転の通知を直接受信することができる。 FIG. 10 is a diagram illustrating a configuration example of the train control system 4 according to the second embodiment. The configurations of the train 1 and the base device 3 of the second embodiment are the same as the configurations of the train 1 and the base device 3 of the first embodiment. The train control system 4 shown in FIG. 10 differs from the train control system 4 of the first embodiment shown in FIG. 5 in the transmission path of signals to the trains 5 and 6. Similarly to the first embodiment, the flow transition detection device 13 according to the second embodiment performs the operation of the flowchart of the first embodiment shown in FIG. Here, in the train 1, when the current detection device 13 determines that the train 1 has been turned over as described above (step S <b> 2: Yes), it transmits a notification of the turnover by broadcasting (step S <b> 4). In other words, when the current detection device 13 of the train 1 determines that the train 1 has been turned over, the notification of the turnover is present in the jurisdiction of the base device 3 and broadcast to other trains that the base device 3 manages the operation. Will be sent. Therefore, other trains can directly receive a turnover notification from the train 1.
　列車５，６すなわち他の列車の動作について説明する。図１１は、実施の形態２にかかる他の列車の動作を示すフローチャートである。他の列車は、列車１から流転の通知を受信する（ステップＳ２１）。他の列車は、流転の通知の内容から自列車の周辺の列車１が流転したと認識して停止する（ステップＳ２２）。他の列車については、運用中で車上制御装置が稼働中であることを想定している。そのため、他の列車は、列車１から流転の通知を受信すると、即座に停止する処理を行うことができる。実施の形態２では、拠点装置３も無線装置２経由で列車１から流転の通知を受信している。そのため、拠点装置３は、管轄内の他の列車に対して停止を指示する制御指令の生成および送信をしなくてもよい。拠点装置３は、管轄範囲が流転検知装置１３の無線通信部１５の通信エリアよりも大きい場合、管轄内の他の列車に対して停止を指示する制御指令を生成して送信してもよい。 The operation of trains 5 and 6, that is, other trains will be described. FIG. 11 is a flowchart illustrating the operation of another train according to the second embodiment. The other trains receive a turnover notification from the train 1 (step S21). The other trains recognize that the train 1 in the vicinity of the own train has flowed from the content of the notice of flow, and stop (step S22). As for other trains, it is assumed that the on-board controller is in operation. Therefore, the other trains can perform a process of stopping immediately when receiving the notice of the turnover from the train 1. In the second embodiment, the base device 3 also receives a turnover notification from the train 1 via the wireless device 2. Therefore, the base device 3 does not have to generate and transmit a control command that instructs the other trains in the jurisdiction to stop. When the jurisdiction range is larger than the communication area of the wireless communication unit 15 of the turnaround detection device 13, the base device 3 may generate and transmit a control command that instructs other trains in the jurisdiction to stop.
　以上説明したように、本実施の形態によれば、列車制御システム４において、他の列車は、列車１から流転の通知を受信した場合は停止することとした。これにより、列車制御システム４では、実施の形態１と同様の効果を得ることができるとともに、他の列車は、実施の形態１のときと比較して、早く停止することができる。 As described above, according to the present embodiment, in the train control system 4, other trains are stopped when receiving a turnover notification from the train 1. Thereby, in train control system 4, while being able to acquire the same effect as Embodiment 1, other trains can be stopped earlier compared with Embodiment 1.
実施の形態３．
　実施の形態３では、列車１は、定期的に拠点装置３に位置情報を送信し、拠点装置３から運用停止時の位置と異なる通知を受信した場合に列車防護を実施する。実施の形態１と異なる部分について説明する。 Embodiment 3 FIG.
In the third embodiment, the train 1 periodically transmits position information to the base device 3, and performs train protection when receiving a notification from the base device 3 that is different from the position when the operation is stopped. A different part from Embodiment 1 is demonstrated.
　実施の形態３の列車１および拠点装置３の構成は、実施の形態１の列車１および拠点装置３の構成と同様である。また、実施の形態３の列車制御システム４の構成も、図１および図５に示す実施の形態１の列車制御システム４の構成と同様であるが、列車１と拠点装置３との間の通信が双方向の通信となる。なお、拠点装置３は、一般的な機能として、列車１の運用停止時の位置情報を列車１から取得し、列車１の運用停止時の位置を把握しているものとする。 The configurations of the train 1 and the base device 3 of the third embodiment are the same as the configurations of the train 1 and the base device 3 of the first embodiment. Further, the configuration of the train control system 4 of the third embodiment is the same as the configuration of the train control system 4 of the first embodiment shown in FIGS. 1 and 5, but communication between the train 1 and the base device 3. Becomes two-way communication. Note that, as a general function, the base device 3 acquires position information when the operation of the train 1 is stopped from the train 1 and grasps the position when the operation of the train 1 is stopped.
　図１２は、実施の形態３にかかる流転検知装置１３が列車１の流転を検知する動作を示すフローチャートである。流転検知装置１３において、流転検知部１４は、列車１が運用停止になると、各センサから検知結果を取得する（ステップＳ３１）。流転検知部１４は、各センサから取得した検知結果に基づいて、現在の列車１の位置を特定し、位置情報を生成する（ステップＳ３２）。流転検知部１４は、ＧＰＳ受信機２１の検知結果を用いることで、位置情報を生成することが可能である。流転検知部１４は、無線通信部１５から位置情報を送信させる（ステップＳ３３）。流転検知部１４は、拠点装置３から、送信した列車１の位置情報と運用停止時の列車１の位置情報とが異なる通知を受信した場合（ステップＳ３４：Ｙｅｓ）、列車１が流転したと判定し、列車防護として、車上制御装置１１を起動し、車上制御装置１１に対してブレーキ１２を制御して列車１を停止させることを指示する（ステップＳ３５）。流転検知部１４は、位置情報を送信してから規定された時間内に、拠点装置３から、送信した列車１の位置情報が運用停止時の列車１の位置情報と異なる通知を受信しなかった場合（ステップＳ３４：Ｎｏ）、処理を終了する。 FIG. 12 is a flowchart illustrating an operation in which the flow change detection device 13 according to the third embodiment detects the flow change of the train 1. In the flow change detection device 13, the flow change detection unit 14 acquires a detection result from each sensor when the operation of the train 1 is stopped (step S31). Based on the detection result acquired from each sensor, the flow detection unit 14 identifies the current position of the train 1 and generates position information (step S32). The flow transition detection unit 14 can generate position information by using the detection result of the GPS receiver 21. The flow detection unit 14 transmits position information from the wireless communication unit 15 (step S33). When the position information of the transmitted train 1 and the position information of the train 1 at the time of operation stop are received from the base unit 3 (step S34: Yes), the current detection unit 14 determines that the train 1 has been turned over. Then, as the train protection, the on-board controller 11 is activated, and the on-board controller 11 is instructed to control the brake 12 to stop the train 1 (step S35). The current detection unit 14 did not receive a notification from the base device 3 that the transmitted position information of the train 1 is different from the position information of the train 1 at the time of operation stoppage, within a prescribed time after transmitting the position information. If so (step S34: No), the process is terminated.
　図１３は、実施の形態３にかかる拠点装置３が列車１から位置情報を受信したときの動作を示すフローチャートである。拠点装置３において、制御部３１は、無線装置２および通信部３２経由で、列車１から列車１の位置情報を取得する（ステップＳ４１）。制御部３１は、取得した列車１の位置情報と、運用停止時の列車１の位置情報とを比較する（ステップＳ４２）。制御部３１は、例えば、取得した列車１の位置情報と運用停止時の列車１の位置情報との差分を算出し、算出した差分の絶対値と規定された閾値とを比較して、２つの位置情報が異なるか否かを判定する。制御部３１は、差分の絶対値が規定された閾値より大きい場合、比較した２つの位置情報が異なるとして（ステップＳ４３：Ｙｅｓ）、２つの位置情報が異なる通知を、通信部３２および無線装置２経由で、列車１に送信する（ステップＳ４４）。また、制御部３１は、管轄内の他の列車に対して停止を指示する制御指令を生成する（ステップＳ４５）。制御部３１は、通信部３２および無線装置２経由で、生成した制御指令を管轄内の他の列車に送信する（ステップＳ４６）。拠点装置３から制御指令を受信した他の列車は、制御指令の内容に従って停止する。制御部３１は、差分の絶対値が規定された閾値以下の場合、２つの位置情報は同じとして（ステップＳ４３：Ｎｏ）、処理を終了する。 FIG. 13 is a flowchart illustrating an operation when the base device 3 according to the third embodiment receives position information from the train 1. In the base device 3, the control unit 31 acquires the position information of the train 1 from the train 1 via the wireless device 2 and the communication unit 32 (step S41). The control unit 31 compares the acquired position information of the train 1 with the position information of the train 1 when the operation is stopped (step S42). For example, the control unit 31 calculates the difference between the acquired position information of the train 1 and the position information of the train 1 when the operation is stopped, compares the calculated absolute value of the difference with a prescribed threshold value, It is determined whether the position information is different. When the absolute value of the difference is larger than the prescribed threshold, the control unit 31 determines that the two pieces of position information compared are different (step S43: Yes), and notifies the communication unit 32 and the wireless device 2 that the two pieces of position information are different. Via, it transmits to the train 1 (step S44). Moreover, the control part 31 produces | generates the control command which instruct | indicates a stop with respect to the other train in jurisdiction (step S45). The control part 31 transmits the produced | generated control command to the other train in jurisdiction via the communication part 32 and the radio | wireless apparatus 2 (step S46). The other trains that have received the control command from the base device 3 stop according to the content of the control command. When the absolute value of the difference is equal to or less than the specified threshold value, the control unit 31 determines that the two pieces of position information are the same (step S43: No), and ends the process.
　以上説明したように、本実施の形態によれば、流転検知装置１３は、位置情報を定期的に拠点装置３に送信し、拠点装置３からの通知に基づいて流転を判定することとした。流転の判定における比較処理を拠点装置３が行うことにより、流転検知装置１３は、実施の形態１と同様の効果を得ることができるとともに、実施の形態１と比較して、処理負荷を低減でき、消費電力を低減することができる。 As described above, according to the present embodiment, the flow transition detection device 13 periodically transmits position information to the base device 3 and determines the flow transition based on the notification from the base device 3. When the base device 3 performs the comparison process in the determination of the flow change, the flow change detection device 13 can obtain the same effect as in the first embodiment and can reduce the processing load as compared with the first embodiment. , Power consumption can be reduced.
実施の形態４．
　実施の形態１では、流転検知装置１３は、複数のセンサを同時に稼働させ、各センサの検知結果に基づいて列車１が流転したか否かを判定していた。実施の形態４では、流転検知装置１３は、最初に１つのセンサを稼働させ、１つのセンサで得られた検知結果が列車１の移動を示すものであった場合、他のセンサを稼働させ、他のセンサから検知結果を取得し、列車１の流転を判定する。実施の形態１と異なる部分について説明する。 Embodiment 4 FIG.
In the first embodiment, the flow transition detection device 13 operates a plurality of sensors at the same time, and determines whether the train 1 has flowed based on the detection result of each sensor. In the fourth embodiment, the flow transition detection device 13 first operates one sensor, and when the detection result obtained by one sensor indicates the movement of the train 1, other sensors are operated, A detection result is acquired from another sensor, and the flow of the train 1 is determined. A different part from Embodiment 1 is demonstrated.
　実施の形態４の列車１および拠点装置３の構成は、実施の形態１の列車１および拠点装置３の構成と同様である。また、実施の形態４の列車制御システム４の構成も、図１および図５に示す実施の形態１の列車制御システム４の構成と同様である。実施の形態４では、流転検知装置１３において、列車１が流転したか否かを判定するまでの動作が実施の形態１と異なる。 The configuration of the train 1 and the base device 3 of the fourth embodiment is the same as the configuration of the train 1 and the base device 3 of the first embodiment. The configuration of the train control system 4 of the fourth embodiment is also the same as the configuration of the train control system 4 of the first embodiment shown in FIGS. The fourth embodiment is different from the first embodiment in the operation until the train turn detection device 13 determines whether or not the train 1 has been run over.
　図１４は、実施の形態４にかかる流転検知装置１３が列車１の流転を検知する動作を示すフローチャートである。流転検知部１４は、列車１が運用停止になると、予め設定された１つのセンサを稼働させ（ステップＳ５１）、稼働中の全てのセンサから検知結果を取得する（ステップＳ５２）。流転検知部１４は、取得した検知結果と、稼働中のセンサに対して列車１の移動を判定するために設定された閾値とを比較する。流転検知部１４は、閾値未満となる検知結果がある場合（ステップＳ５３：Ｎｏ）、処理を終了する。流転検知部１４は、稼働中のセンサから取得した全ての検知結果において、検知結果が閾値以上の場合（ステップＳ５３：Ｙｅｓ）、規定された数のセンサが稼働中か否かを判定する（ステップＳ５４）。流転検知部１４は、規定された数のセンサが稼働中ではない場合（ステップＳ５４：Ｎｏ）、稼働していないセンサから１つを選択し、選択したセンサを稼働させる（ステップＳ５５）。流転検知部１４は、ステップＳ５２に戻って上記動作を繰り返し実施する。 FIG. 14 is a flowchart showing an operation of detecting the turning of the train 1 by the turning control device 13 according to the fourth embodiment. When the train 1 stops operation, the current transfer detection unit 14 operates one preset sensor (step S51), and acquires detection results from all operating sensors (step S52). The flow transition detection unit 14 compares the acquired detection result with a threshold set for determining movement of the train 1 with respect to the sensor in operation. If there is a detection result that is less than the threshold value (step S53: No), the flow transition detection unit 14 ends the process. In all the detection results acquired from the active sensors, the flow transition detection unit 14 determines whether or not the specified number of sensors are in operation (step S53: Yes) (step S53). S54). If the prescribed number of sensors is not in operation (step S54: No), the flow transition detection unit 14 selects one of the sensors that are not in operation, and operates the selected sensor (step S55). The flow detection unit 14 returns to step S52 and repeats the above operation.
　流転検知部１４は、規定された数のセンサが稼働中の場合（ステップＳ５４：Ｙｅｓ）、列車１が流転したと判定する（ステップＳ５６）。流転検知部１４は、列車防護として、車上制御装置１１を起動し、車上制御装置１１に対してブレーキ１２を制御して列車１を停止させることを指示する（ステップＳ５７）。また、流転検知部１４は、列車防護として、列車１が流転したことを示す通知を無線通信部１５からブロードキャストで送信させる（ステップＳ５８）。ステップＳ５７およびステップＳ５８の動作は、図４に示す実施の形態１のフローチャートのステップＳ３およびステップＳ４の動作と同様である。 If the specified number of sensors are in operation (step S54: Yes), the current flow detection unit 14 determines that the train 1 has been turned (step S56). As the train protection, the flow detection unit 14 activates the on-board controller 11 and instructs the on-board controller 11 to control the brake 12 to stop the train 1 (step S57). In addition, the current detection unit 14 broadcasts a notification indicating that the train 1 has been turned over as a train protection from the wireless communication unit 15 (step S58). The operations in step S57 and step S58 are the same as the operations in step S3 and step S4 in the flowchart of the first embodiment shown in FIG.
　なお、図１４に示すフローチャートの例では、流転検知装置１３において、稼働するセンサを１つずつ増やしていく場合について説明したが、稼働させるセンサの数はこれに限定されない。流転検知装置１３は、例えば、最初に１つのセンサを稼働させ、検知結果が閾値以上の場合、稼働していなかった残りのセンサを全て稼働させてもよい。また、流転検知装置１３は、最初に複数のセンサを稼働させ、各検知結果が閾値以上の場合、稼働していなかったセンサからさらに複数のセンサを選択し、稼働させるセンサを増やしていってもよい。このように、流転検知部１４は、複数のセンサのうち１以上のセンサを稼働し、１以上のセンサから列車１の移動を示す検知結果、すなわち閾値以上の検知結果を取得した場合、複数のセンサのうち稼働していなかったセンサを稼働させ、稼働させたセンサの検知結果に基づいて列車１が流転したか否かを判定する。流転検知部１４は、例えば、最初に、加速度センサ１７、地磁気センサ１８、およびジャイロセンサ１９を稼働させ、各センサの検知結果が全て閾値以上であった場合、つぎにＧＰＳ受信機２１を稼働させてもよい。 In the example of the flowchart shown in FIG. 14, the case where the number of sensors to be operated is increased one by one in the flow transition detection device 13, but the number of sensors to be operated is not limited to this. For example, the current transfer detection device 13 may operate one sensor first, and if the detection result is equal to or greater than the threshold value, may operate all remaining sensors that are not operating. In addition, the flow transition detection device 13 operates a plurality of sensors first, and when each detection result is equal to or greater than the threshold, even if a plurality of sensors are selected from the sensors that have not been operated and the number of sensors to be operated is increased. Good. As described above, the flow transition detection unit 14 operates one or more sensors among the plurality of sensors, and when the detection result indicating the movement of the train 1 from one or more sensors, that is, the detection result equal to or greater than the threshold value, The sensor which was not operating among the sensors is operated, and it is determined whether or not the train 1 has been turned over based on the detection result of the operated sensor. For example, the flow transition detection unit 14 first activates the acceleration sensor 17, the geomagnetic sensor 18, and the gyro sensor 19, and when all the detection results of the sensors are equal to or greater than the threshold value, the GPS receiver 21 is activated next. May be.
　実施の形態４において、拠点装置３および他の列車は、実施の形態１または実施の形態２のときと同様の動作を実施する。 In the fourth embodiment, the base device 3 and other trains perform the same operation as in the first embodiment or the second embodiment.
　以上説明したように、本実施の形態によれば、流転検知装置１３は、最初に一部のセンサを稼働させ、検知結果が閾値以上すなわち移動を示す内容であって場合、稼働させるセンサを増やして、列車１の流転を判定することとした。これにより、流転検知装置１３は、実施の形態１と同様の効果を得ることができるとともに、流転の誤検知を防止しつつ、実施の形態１と比較して、消費電力を低減することができる。 As described above, according to the present embodiment, the advection detection device 13 first activates some sensors, and increases the number of sensors to be activated when the detection result is equal to or greater than a threshold, that is, indicates movement. Therefore, it was decided to determine the flow of the train 1. As a result, the flow transition detection device 13 can obtain the same effects as those of the first embodiment, and can reduce power consumption compared to the first embodiment while preventing erroneous detection of the flow transition. .
　以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention.
