　ステップＳ４０１では、運用状態推定部２０１は、入力される列車の運行情報から走行路線情報（例えば、列車番号、時刻表情報、列車種別、現在駅、次停車駅、編成分割／併結運用等の特殊運用実施駅など）を取得し、列車の運用状態の推定要素の１つとして用いる。 In step S401, the operation state estimation unit 201 uses the train operation information that is input to the travel route information (for example, train number, timetable information, train type, current station, next stop station, special division/consolidation operation, etc.). The operating station, etc.) is acquired and used as one of the factors for estimating the train operation status.
　ステップＳ４０２では、運用状態推定部２０１は、入力される速度発電機等１２４（速度発電機、接続機器など）から得られる列車の速度情報をもとに、列車の走行距離の演算を行い、自列車の位置および列車の走行状態を特定し、列車の運用状態の推定要素の１つとして用いる。 In step S402, the operation state estimation unit 201 calculates the running distance of the train based on the train speed information obtained from the input speed generator or the like 124 (speed generator, connected device, etc.), The position of the train and the running state of the train are specified and used as one of the factors for estimating the operating state of the train.
　ステップＳ４０３において、運用状態推定部２０１は、入力される乗務員の操作情報（例えば、マスターコントローラ１２０の操作情報、各種スイッチ１２６の操作情報、各種操作コック１２７の操作情報）を取得し、列車の運用状態の推定要素の１つとして用いる。 In step S403, the operation state estimating unit 201 acquires the operation information of the crewmembers (for example, the operation information of the master controller 120, the operation information of the various switches 126, the operation information of the various operation cocks 127) input, and the operation of the train. It is used as one of the state estimation elements.
　ステップＳ４０４において、運用状態推定部２０１は、入力される列車の動作情報（例えば、各種車両回路の動作情報（扉１２１、パンタグラフ１２９等の動作情報）、各種機器１２２の動作情報、故障情報など）を取得し、列車の運用状態の推定要素の１つとして用いる。 In step S404, the operation state estimation unit 201 receives input train operation information (for example, operation information of various vehicle circuits (operation information of the door 121, pantograph 129, etc.), operation information of various devices 122, failure information, etc.). Is acquired and used as one of the factors for estimating the train operation state.
　ステップＳ４０５において、運用状態推定部２０１は、上述のステップＳ４０１～ステップＳ４０４において取得した情報に基づいて、自列車の運用状態を推定し、推定した結果をカメラ画像データ量決定部２０２に通知する。例えば、運用状態推定部２０１は、カメラ選定テーブル３００を用いて、取得した運行情報、操作情報、動作情報に応じて規定される列車の運用状態を取得する。 In step S405, the operation state estimation unit 201 estimates the operation state of the own train based on the information acquired in steps S401 to S404 described above, and notifies the camera image data amount determination unit 202 of the estimation result. For example, the operation state estimation unit 201 uses the camera selection table 300 to obtain the operation state of the train defined according to the acquired operation information, operation information, and operation information.
　以上により、運用状態推定部２０１における一連の処理が終了する。 With the above, a series of processing in the operation state estimation unit 201 is completed.
　次に、カメラ画像データ量決定部２０２が列車の運用状態に基づいて運転台表示器１１２に表示する画像のデータ量を決定する処理（データ量決定処理）について説明する。データ量決定処理は、例えば、運用状態推定部２０１により列車の運用状態の推定結果がカメラ画像データ量決定部２０２に通知されることを契機に開始される。 Next, a process (data amount determination process) in which the camera image data amount determination unit 202 determines the data amount of the image displayed on the cab display 112 based on the operating state of the train will be described. The data amount determination process is started, for example, when the operation state estimation unit 201 notifies the camera image data amount determination unit 202 of the estimation result of the train operation state.
　図５は、カメラ画像データ量決定部２０２によって実行されるデータ量決定処理に係るフローチャートの一例を示す図である。 FIG. 5 is a diagram showing an example of a flowchart relating to the data amount determination processing executed by the camera image data amount determination unit 202.
　ここで、車両情報制御装置１１１は、データ量決定処理で使用するパラメータ５００を備える。パラメータ５００は、例えば、記憶部１１４に記憶されている。パラメータ５００には、例えば、画像の通信用（画像配信用）に割り当てるデータ帯域Ｘ［ｂｉｔ／ｓｅｃ］、メイン画像の配信周期ａ［ｓｅｃ］、サブ画像の配信周期ｂ［ｓｅｃ］、メイン画像のデータ量Ａ［ｂｉｔ］、サブ画像のデータ量Ｂ［ｂｉｔ］が含まれる。 Here, the vehicle information control device 111 includes a parameter 500 used in the data amount determination process. The parameter 500 is stored in, for example, the storage unit 114. The parameter 500 includes, for example, a data band X [bit/sec] allocated for image communication (for image distribution), a main image distribution cycle a [sec], a sub image distribution cycle b [sec], and a main image distribution cycle. The data amount A [bit] and the sub image data amount B [bit] are included.
　データ帯域Ｘは、先頭車両の車両情報制御装置１１１と中間車両の車両情報制御装置１１１とを接続するネットワークの帯域であってもよいし、先頭車両内のネットワークの帯域であってもよいし、両ネットワークの帯域うち、小さい方の帯域であってもよいし、その他の帯域であってもよい。また、データ帯域Ｘは、固定の値であってもよいし、制御情報配信用に割り当てるデータ帯域に応じて動的に変動する値であってもよい。メイン画像の配信周期ａとサブ画像の配信周期ｂとは、同じ値であってもよいし、異なる値であってもよい。メイン画像のデータ量Ａとサブ画像のデータ量Ｂとは、同じ値であってもよいし、異なる値であってもよい。 The data band X may be a band of a network connecting the vehicle information control device 111 of the leading vehicle and the vehicle information control device 111 of the intermediate vehicle, or may be a band of a network in the leading vehicle, Of the bands of both networks, the smaller band may be used, or another band may be used. The data band X may be a fixed value or may be a value that dynamically changes according to the data band assigned for control information distribution. The main image delivery cycle a and the sub image delivery cycle b may have the same value or different values. The data amount A of the main image and the data amount B of the sub image may have the same value or different values.
　ステップＳ５０１では、カメラ画像データ量決定部２０２は、運用状態推定部２０１から通知される列車の運用状態の推定結果を取得する。 In step S501, the camera image data amount determination unit 202 acquires the train operation state estimation result notified from the operation state estimation unit 201.
　ステップＳ５０２では、カメラ画像データ量決定部２０２は、ステップＳ５０１で取得した列車の運用状態の推定結果に対応する表示候補（メイン画像およびサブ画像）を判別する。例えば、カメラ画像データ量決定部２０２は、カメラ選定テーブル３００を用いて、メイン画像に表示するための画像を配信する対象のカメラと、サブ画像に表示するための画像を配信する対象のカメラ（例えば、カメラ番号）と、サブ画像の表示数ｎとを決定する。なお、対象のカメラは、図１に示す車両の各箇所に配置された複数のカメラに対してユニークに割り振られるものとする。 In step S502, the camera image data amount determination unit 202 determines the display candidates (main image and sub image) corresponding to the train operation state estimation result acquired in step S501. For example, the camera image data amount determination unit 202 uses the camera selection table 300 to distribute the image to be displayed in the main image and the camera to be distributed in the sub image ( For example, the camera number) and the display number n of sub-images are determined. It should be noted that the target camera is uniquely assigned to the plurality of cameras arranged at each location of the vehicle shown in FIG.
　ステップＳ５０３では、カメラ画像データ量決定部２０２は、ステップＳ５０２で決定した結果およびパラメータ５００を用いて、メイン画像のデータ帯域Ｐ（＝Ａ÷ａ）を算出する。 In step S503, the camera image data amount determination unit 202 calculates the data band P (=A÷a) of the main image using the result determined in step S502 and the parameter 500.
　ステップＳ５０４では、カメラ画像データ量決定部２０２は、ステップＳ５０３で算出したメイン画像のデータ帯域Ｐと画像配信用に割り当てるデータ帯域Ｘとを比較する。カメラ画像データ量決定部２０２は、ＸがＰ以下であると判定した場合、ステップＳ５０５に処理を移し、ＸがＰより大きいと判定した場合、ステップＳ５０７に処理を移す。 In step S504, the camera image data amount determination unit 202 compares the data band P of the main image calculated in step S503 with the data band X allocated for image distribution. The camera image data amount determination unit 202 moves the process to step S505 when it is determined that X is less than or equal to P, and moves the process to step S507 when it is determined that X is greater than P.
　ステップＳ５０５では、カメラ画像データ量決定部２０２は、メイン画像のデータ帯域情報Ｐが画像配信用に割り当てるデータ帯域Ｘ以上であるので、メイン画像のデータ量Ａ’（＝Ｘ×ａ）を算出する。 In step S505, the camera image data amount determination unit 202 calculates the data amount A′ (=X×a) of the main image because the data band information P of the main image is equal to or larger than the data band X allocated for image distribution. ..
　ステップＳ５０６では、カメラ画像データ量決定部２０２は、サブ画像のデータ量を「０（ゼロ）」として算出する。 In step S506, the camera image data amount determination unit 202 calculates the data amount of the sub image as “0 (zero)”.
　ステップＳ５０７では、カメラ画像データ量決定部２０２は、メイン画像のデータ帯域Ｐが画像配信用に割り当てるデータ帯域Ｘ未満であるので、メイン画像のデータ量をＡとして算出する。 In step S507, the camera image data amount determination unit 202 calculates the data amount of the main image as A because the data band P of the main image is less than the data band X allocated for image distribution.
　ステップＳ５０８では、カメラ画像データ量決定部２０２は、サブ画像のデータ量Ｂ’（＝（Ｘ－Ｐ）×ｂ÷ｎ）を算出する。 In step S508, the camera image data amount determination unit 202 calculates the sub image data amount B′ (=(X−P)×b÷n).
　ステップＳ５０９では、カメラ画像データ量決定部２０２は、ステップＳ５０８で算出したサブ画像のデータ量をＢ’とサブ画像のデータ量Ｂとを比較する。カメラ画像データ量決定部２０２は、ＢがＢ’以下であると判定した場合、ステップＳ５１０に処理を移し、ＢがＢ’より大きいと判定した場合、ステップＳ５１１に処理を移す。 In step S509, the camera image data amount determination unit 202 compares the sub-image data amount B′ calculated in step S508 with the sub-image data amount B. The camera image data amount determination unit 202 moves the process to step S510 when it is determined that B is equal to or smaller than B′, and moves the process to step S511 when it is determined that B is greater than B′.
　ステップＳ５１０では、カメラ画像データ量決定部２０２は、算出したサブ画像のデータ量Ｂ’がサブ画像のデータ量Ｂ以上であるので、サブ画像のデータ量をＢとして算出する。 In step S510, the camera image data amount determination unit 202 calculates the data amount of the sub image as B because the calculated data amount B′ of the sub image is greater than or equal to the data amount B of the sub image.
　ステップＳ５１１では、カメラ画像データ量決定部２０２は、算出したサブ画像のデータ量Ｂ’がサブ画像のデータ量Ｂ未満であるので、サブ画像のデータ量をＢ’として算出する。 In step S511, the camera image data amount determination unit 202 calculates the data amount of the sub image as B′ because the calculated data amount B′ of the sub image is less than the data amount B of the sub image.
　例えば、列車に設けられるカメラに、異なるスペックのカメラ（例えば、高画質の画像を撮像するカメラ、低画質の画像を撮像するカメラ）が含まれる場合、上述したように、列車の運用状態に応じてデータ量を計算することが好適である。 For example, when the cameras provided in the train include cameras with different specifications (for example, a camera that captures a high-quality image and a camera that captures a low-quality image), as described above, depending on the operating state of the train. It is preferable to calculate the amount of data by
　以上により、カメラ画像データ量決定部２０２における一連の処理が終了する。 With the above, a series of processing in the camera image data amount determination unit 202 is completed.
　データ量決定処理では、列車の運用状態に応じて、データ量を計算する方法について説明したが、これに限られるものではない。例えば、列車の運用状態に応じて、記憶部１１４に記憶した情報を読込むことでデータ量を決定してもよい。例えば、カメラ選定テーブル３００にけるメイン画像カメラ情報３０５おいて、カメラの識別情報とデータ量とが規定され、サブ画像カメラ情報３０６おいて、カメラの識別情報とデータ量とが規定され、カメラ選定テーブル３００を用いてデータ量が決定されてもよい。 In the data amount determination process, the method of calculating the data amount according to the operating state of the train has been explained, but the method is not limited to this. For example, the data amount may be determined by reading the information stored in the storage unit 114 according to the operating state of the train. For example, the main image camera information 305 in the camera selection table 300 defines the camera identification information and the data amount, and the sub image camera information 306 defines the camera identification information and the data amount. The amount of data may be determined using the table 300.
　次に、選定したカメラに対して画像のデータ量を通知する処理（データ量通知処理）について説明する。データ量通知処理は、例えば、カメラ画像データ量決定部２０２によりメイン画像のデータ量などがカメラ画像データ量通知部２０３に通知されることを契機に開始される。 Next, the process of notifying the selected camera of the amount of image data (data amount notification process) will be described. The data amount notification process is started, for example, when the camera image data amount determination unit 202 notifies the camera image data amount notification unit 203 of the data amount of the main image and the like.

　ステップＳ６０１では、カメラ画像データ量通知部２０３は、カメラ画像データ量決定部２０２から通知されるメイン画像およびサブ画像の表示対象のカメラ番号および各画像のデータ量と、各画像の配信周期ａ，ｂとを取得する。 In step S601, the camera image data amount notification unit 203 informs the camera image data amount determination unit 202 of the camera numbers of the display targets of the main image and the sub images, the data amount of each image, the distribution cycle a of each image, Get b and.
　ステップＳ６０２では、カメラ画像データ量通知部２０３は、メイン画像の表示対象のカメラ番号のカメラに、メイン画像のデータ量を、メイン画像の配信周期ａにて通知する。 In step S602, the camera image data amount notification unit 203 notifies the camera of the camera number of the display target of the main image of the data amount of the main image at the main image distribution cycle a.
　ステップＳ６０３では、カメラ画像データ量通知部２０３は、サブ画像の表示対象のカメラ番号のカメラに、サブ画像のデータ量を、サブ画像の配信周期ｂにて通知する。 In step S603, the camera image data amount notification unit 203 notifies the camera of the camera number of the display target of the sub image of the data amount of the sub image at the sub image distribution cycle b.
　以上により、カメラ画像データ量通知部２０３における一連の処理が終了する。 With the above, a series of processing in the camera image data amount notification unit 203 is completed.
　次に、運転台表示器１１２に画像の表示データを送信する処理（表示データ送信処理）について説明する、表示データ送信処理は、カメラより送信された画像データをカメラ画像表示データ送信部２０４が受信したことを契機に開始される。 Next, a process of transmitting display data of an image to the cab display 112 (display data transmitting process) will be described. In the display data transmitting process, the camera image display data transmitting unit 204 receives the image data transmitted from the camera. It is started when you do it.
　図７は、カメラ画像表示データ送信部２０４にて実行される表示データ送信処理に係るフローチャートの一例を示す図である。 FIG. 7 is a diagram showing an example of a flowchart relating to display data transmission processing executed by the camera image display data transmission unit 204.
　ステップＳ７０１では、カメラ画像表示データ送信部２０４は、車両の各カメラから画像（画像データ）を受信する。また、ステップＳ７０１では、カメラ画像表示データ送信部２０４は、カメラ画像データ量決定部２０２から通知されるメイン画像表示指令とメイン画像およびサブ画像の表示対象のカメラ番号とを受信する。 In step S701, the camera image display data transmission unit 204 receives an image (image data) from each camera of the vehicle. Further, in step S701, the camera image display data transmission unit 204 receives the main image display command and the camera number of the display target of the main image and the sub image notified from the camera image data amount determination unit 202.
　ステップＳ７０２では、カメラ画像表示データ送信部２０４は、メイン画像の表示対象のカメラから受信した画像データをメイン画像表示指令とともに表示データとして運転台表示器１１２に送信する。 In step S<b>702, the camera image display data transmission unit 204 transmits the image data received from the main image display target camera to the cab display 112 as display data together with the main image display command.
　ステップＳ７０３では、カメラ画像表示データ送信部２０４は、サブ画像の表示対象のカメラから受信した画像データをサブ画像表示指令とともに表示データとして運転台表示器１１２に送信する。 In step S703, the camera image display data transmission unit 204 transmits the image data received from the sub-image display target camera to the cab display 112 as display data together with the sub-image display command.
　以上により、カメラ画像表示データ送信部２０４における一連の処理が終了する。 With the above, a series of processing in the camera image display data transmission unit 204 is completed.
　次に、運転台表示器１１２における、列車の運用を支援するカメラの画像（運用支援カメラ画像）の画面表示について説明する。 Next, the screen display of the image of the camera (operation support camera image) that supports train operation on the cab display 112 will be described.
　図８は、運用支援カメラ画像の画面表示の一例（運用支援カメラ画像表示画面８００）を示す図である。 FIG. 8 is a diagram showing an example of a screen display of the operation support camera image (operation support camera image display screen 800).
　運用支援カメラ画像表示画面８００では、メイン画像表示指令に基づいてメイン画像を表示するためのメイン画像表示領域８０１と、サブ画像表示指令に基づいてサブ画像を表示するためのサブ画像表示領域８０２とを含んで構成される。 On the operation support camera image display screen 800, a main image display area 801 for displaying the main image based on the main image display command, and a sub image display area 802 for displaying the sub image based on the sub image display command. It is configured to include.
　図９は、運転台表示器１１２に表示された画像（メイン画像およびサブ画像）の一例を示す図である。 FIG. 9 is a diagram showing an example of images (main image and sub image) displayed on the cab display 112.
　Ａ駅から列車が出発し、列車速度がＣｋｍ／ｈに達する第１の運用状態では、乗務員による各種操作が行われる推定で、メイン画像として、各種スイッチ１２６を撮影するカメラ１３４のカメラ画像９０１が表示され、第１のサブ画像として、乗務員による各種操作が行われる推定で、各種操作コック１２７を撮影するカメラ１３８のカメラ画像９０２が表示され、第２のサブ画像として。列車の発車後に乗客などの扉１２１への挟まりの可能性を推定して、扉１２１を撮影するカメラ１３７のカメラ画像９０３が表示された。 In the first operating state where the train departs from the A station and the train speed reaches Ckm/h, it is estimated that various operations are performed by the crew members, and the camera image 901 of the camera 134 that captures the various switches 126 is estimated as the main image. As a second sub-image, a camera image 902 of the camera 138 that captures the various operation cocks 127 is displayed as a first sub-image, with various operations performed by a crew member. A camera image 903 of the camera 137 that captures the door 121 is displayed by estimating the possibility that a passenger or the like will be caught in the door 121 after the train departs.
　列車速度がＣｋｍ／ｈに達した第２の運用状態では、速度が速い状態であるため、列車正面と障害物との衝突による事態を推定し、メイン画像として、前方向状況を確認するためのカメラ１３０のカメラ画像９１１が表示され、第１のサブ画像として、列車側面と障害物との衝突による事態を推定し、車両の側面を撮影するカメラ１３５のカメラ画像９１２が表示され、第２のサブ画像として、乗務員による各種操作が行われる推定で、各種スイッチ１２６を撮影するカメラ１３４のカメラ画像９１３が表示された。 In the second operating state where the train speed reaches Ckm/h, the speed is high, so the situation due to the collision between the front of the train and the obstacle is estimated, and the main image is used to confirm the forward direction. The camera image 911 of the camera 130 is displayed, and as the first sub-image, the camera image 912 of the camera 135 that estimates the situation due to the collision between the train side surface and the obstacle and captures the side surface of the vehicle is displayed. As a sub-image, a camera image 913 of the camera 134 that captures the various switches 126 is displayed on the assumption that various operations are performed by the crew.
　Ｂ駅への到着が近くなり、列車速度がＣｋｍ／ｈから減速が開始された第３の運用状態では、駅への停車を推定し、メイン画像として、停車目標位置を撮影するためのカメラ１３１のカメラ画像９２１が表示され、第１のサブ画像として、駅のホームに列車が進入した際に列車側面と障害物との衝突による事態を推定し、車両の側面を撮影するカメラ１３５のカメラ画像９２２が表示され、第２のサブ画像として、駅への到着後に扉１２１が開く際の乗客の接触防止を監視する推定で、扉１２１を撮影するカメラ１３７のカメラ画像９２３が表示された。 In the third operating state in which the train arrives at station B soon and the train speed starts decelerating from Ckm/h, the camera 131 for estimating the stop at the station and photographing the stop target position as the main image is displayed. Camera image 921 is displayed, and as the first sub-image, when the train enters the platform of the station, the situation due to the collision between the train side surface and the obstacle is estimated, and the camera image of the camera 135 that shoots the side surface of the vehicle is displayed. 922 is displayed, and as the second sub-image, the camera image 923 of the camera 137 that captures the door 121 is displayed with the estimation that monitors the contact prevention of passengers when the door 121 opens after arrival at the station.
　上述の例では、各運用状態が継続するケースについて説明したが、これに限られるものではない。例えば、第１の運用状態において、非常通報装置１２５が作動して他の運用状態になったときには、メイン画像、サブ画像は、他の運用状態に対応した画像に切り替えられる。 In the above example, the case where each operation state continues is explained, but it is not limited to this. For example, in the first operating state, when the emergency notification device 125 is activated to enter another operating state, the main image and the sub image are switched to images corresponding to the other operating state.
　このように、列車の運用状態に合わせて画像のデータ量を制御することで、車両内の通信網で逼迫しても、列車の運用状態に合わせて乗務員が確認したい画像を優先できるようになる。 In this way, by controlling the amount of image data according to the operating status of the train, it is possible to give priority to the images that the crew members want to check according to the operating status of the train, even if the communication network in the train is tight. ..
　上述した構成によれば、列車の運用状態に合わせて画像のデータ量を制御することで、列車の運用状態に合わせて乗務員が確認したい画像のデータ量を車両内の通信網に流す指令を各カメラへ行うことができ、当該画像の車両内の通信網での欠落防止効果が期待できる。 According to the above-described configuration, by controlling the image data amount according to the train operation state, each command to send the image data amount that the crew member wants to confirm to the train communication state according to the train operation state is sent. It can be applied to the camera, and the effect of preventing the loss of the image in the communication network in the vehicle can be expected.
　本実施の形態によれば、列車の運用状態を推定し、車両各箇所に配置されたカメラ画像の中から運用状態に応じて運転台表示器に画面表示するために必要なデータ量を制御することにより、画面表示する必要のないカメラから画像データの送信を抑止することができる。また、画面表示する必要のある画像データの中でも、メイン画像に表示する画像の通信に用いるデータ帯域を優先して確保することができる。 According to the present embodiment, the operating state of the train is estimated, and the amount of data required for screen display on the cab display is controlled according to the operating state from the camera images arranged at each location of the vehicle. As a result, it is possible to suppress the transmission of image data from a camera that does not need to be displayed on the screen. Further, among the image data that need to be displayed on the screen, the data band used for communication of the image displayed on the main image can be preferentially secured.
