Description
本発明は、列車制御システムに係り、特に、列車の併合または列車の分割を行う場合でも、適正に列車の制御を行うことを可能とした列車制御システムに関する。
The present invention relates to a train control system, and more particularly, to a train control system that enables proper train control even when trains are merged or trains are divided.
従来、軌道を走行する列車の列車位置を検知する列車位置検知システムとしては、いわゆる無線測距方式を利用した列車制御システムが知られている。このような無線測距方式を利用した列車制御システムにおいては、列車に車上無線機を搭載し、その列車の走行する軌道の沿線に沿って所定の間隔をもって設置された複数の沿線無線機との間で無線ネットワークを形成し、車上無線機の車上アンテナと沿線無線機の沿線アンテナとの無線伝搬遅延（時間）を計測して列車位置を検知し、その検知された列車位置に基づいて列車制御を行うようになっている。
Conventionally, a train control system using a so-called wireless ranging method is known as a train position detection system for detecting the train position of a train traveling on a track. In a train control system using such a radio ranging system, on-board wireless devices are mounted on a train, and a plurality of alongside wireless devices installed at predetermined intervals along the track along which the train travels. A wireless network is formed between them, and the train position is detected by measuring the radio propagation delay (time) between the on-board antenna of the on-board radio and the along-line antenna of the along-line radio, and based on the detected train position Train control.
そして、このような列車制御システムとしては、従来から、例えば、所定の軌道を走行する列車に搭載された車上無線機および地上の所定位置に設けられた地上無線機間の無線の伝播時間に基づいてその所定の軌道における列車位置を検知する無線列車位置検知手段と、列車の車軸に接続された速度発電機の出力信号に基づいて所定の軌道における列車の走行距離を算出する走行距離算出手段と、無線列車位置検知手段で検知された列車位置を所定の仮基準位置に設定する仮基準位置設定手段と、その仮基準位置設定手段で設定された仮基準位置から走行距離算出手段で算出された走行距離に基づいて所定の軌道における列車位置を検知する列車位置検知算出手段とを備えた技術が開示されている（例えば、特許文献１を参照。）。
As such a train control system, conventionally, for example, in the radio propagation time between an on-board radio mounted on a train traveling on a predetermined track and a ground radio installed at a predetermined position on the ground A wireless train position detecting means for detecting the train position on the predetermined track based on the travel distance calculating means for calculating the travel distance of the train on the predetermined track based on the output signal of the speed generator connected to the axle of the train Calculated by the travel distance calculating means from the temporary reference position setting means for setting the train position detected by the wireless train position detecting means to a predetermined temporary reference position, and the temporary reference position set by the temporary reference position setting means. A technology including train position detection calculation means for detecting a train position on a predetermined track based on the travel distance is disclosed (see, for example, Patent Document 1).
しかしながら、前記従来の技術においては、２つの列車を連結して１の列車に併合する場合、または、１つの列車の連結を外して２つの列車に分割する場合に、各列車により無線測距による列車の位置検出を行って列車の走行制御を行おうとすると、列車の併合を行うために２つの列車が接近した場合、または、列車の分割を行って２つの列車が接近した状態となった場合に、車上装置が、併合相手の列車または分割後の相手列車を接近列車として認識してしまうという問題を有している。そのため、列車接近により、非常ブレーキが動作してしまい、列車が走行不能になってしまうという問題を有している。
However, in the conventional technology, when two trains are connected and merged into one train, or when one train is disconnected and divided into two trains, each train uses radio ranging. When the train position is detected and the train traveling control is performed, the two trains approach to merge the trains, or the trains are divided and the two trains approach each other In addition, the on-board device has a problem that the merged opponent train or the divided opponent train is recognized as an approaching train. Therefore, there is a problem that the emergency brake operates due to the approach of the train, and the train cannot travel.

以下、本発明の実施形態について図面を参照して説明する。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１は、本発明に係る列車位置検知システムの実施形態を示す概略構成図であり、本実施形態においては、所定の軌道１上を走行する列車２には、車上装置３が搭載されている。この車上装置３は、ＣＰＵを中心に構成された演算処理部を有しており、列車２の速度制御や制動制御などの各種制御を行うように構成されている。
FIG. 1 is a schematic configuration diagram showing an embodiment of a train position detection system according to the present invention. In this embodiment, an on-board device 3 is mounted on a train 2 traveling on a predetermined track 1. Yes. The on-board device 3 has an arithmetic processing unit mainly composed of a CPU, and is configured to perform various controls such as speed control and braking control of the train 2.
列車２には、車上装置３に接続された車上無線機４が搭載されており、この車上無線機４は、列車２の最前車両および最後尾車両にそれぞれ設置されて、一対の車上無線機４により通信を行うように構成されている。
The train 2 is equipped with an on-board radio device 4 connected to the on-board device 3. The on-board radio device 4 is installed in the foremost vehicle and the last vehicle of the train 2, respectively. Communication is performed by the upper wireless device 4.
また、列車２の軌道１に沿って所定間隔毎に、車上無線機４との間で送受信を行うための複数の沿線無線機５が設置されており、これら沿線無線機５には、地上装置６が接続されている。地上装置６は、沿線無線機５と車上無線機４との無線の伝搬時間に基づいて列車２の現在の位置を演算して求めるように構成されており、これら車上無線機４、沿線無線機５および地上装置６により、いわゆる無線測距方式を利用した列車制御システムが構成されている。そして、地上装置６により求められた列車２の現在位置情報を沿線無線機５および車上無線機４を介して車上装置３に送り、車上装置３は、列車２の現在位置情報に基づいて列車２の速度制御およびブレーキ制御を行うように構成されている。
In addition, a plurality of trackside radios 5 for performing transmission / reception with the onboard radio device 4 are installed at predetermined intervals along the track 1 of the train 2. A device 6 is connected. The ground device 6 is configured to calculate and obtain the current position of the train 2 based on the radio propagation time between the along-line radio 5 and the on-board radio 4. The radio device 5 and the ground device 6 constitute a train control system using a so-called radio distance measuring method. Then, the current position information of the train 2 obtained by the ground device 6 is sent to the on-board device 3 via the lineside radio device 5 and the on-board wireless device 4, and the on-board device 3 is based on the current position information of the train 2. The train 2 is configured to perform speed control and brake control.
ここで、本実施形態においては、列車２が走行する路線の所定の位置に、２つの列車２を連結して１つの列車２に併合させたり、連結された１つの列車２を２つの列車２に分割させるための併合分割許可領域をあらかじめ設定するように構成されており、この併合分割許可領域としては、例えば、駅構内や列車２の車庫などが考えられる。
Here, in the present embodiment, two trains 2 are connected to a predetermined position on the route on which the train 2 travels and merged into one train 2, or one connected train 2 is connected to two trains 2. For example, the merge division permission area may be a station yard or a garage of the train 2.
また、本実施形態においては、図３に示すように、車上装置３は、列車２の現在位置情報に基づいて、列車２が併合分割許可領域に存在していると判断した場合に、一方の車上無線機４による動作を停止するように構成されている（図中破線参照）。この動作を停止する車上無線機４は、列車２を併合する場合は、併合分割許可領域に２つの列車２が存在しており、各列車２は、車上装置３により、連結する方向をあらかじめ認識していることから、各列車２が連結する側の車上無線機４をそれぞれ停止させるように構成されている。
Further, in the present embodiment, as shown in FIG. 3, when the on-board device 3 determines that the train 2 is present in the merge division permitted area based on the current position information of the train 2, The operation by the on-board wireless device 4 is stopped (see the broken line in the figure). When the on-board radio 4 that stops this operation merges the trains 2, there are two trains 2 in the merge-permitted permission area, and each train 2 is connected in the direction to be connected by the on-board device 3. Since it recognizes beforehand, it is comprised so that the on-board radio | wireless machine 4 of the side which each train 2 connects may be stopped, respectively.
そして、列車２が併合する場合に、車上装置３は、列車２が併合分割許可領域内に存在している間は、他の列車２を認識しないように制御するように構成されている。すなわち、列車２が併合分割許可領域内において、併合しようとした場合、併合すべき他の列車２が存在するため、車上装置３により、併合すべき他の列車２を認識してしまうと、非常ブレーキが動作してしまい、列車２の併合を行うことができなくなってしまうため、この併合すべき他の列車２を認識しないように制御するものである。
And when the train 2 merges, the on-board device 3 is configured to perform control so as not to recognize other trains 2 while the train 2 exists in the merge-permitted permission area. That is, when the train 2 is to be merged within the merge division allowed area, there are other trains 2 to be merged, so when the on-board device 3 recognizes the other trains 2 to be merged, Since the emergency brake is operated and the trains 2 cannot be merged, control is performed so as not to recognize the other trains 2 to be merged.
また、列車２を分割する場合は、図４に示すように、各列車２は、車上装置３により、列車２が分割する方向をあらかじめ認識していることから、各列車２が分割する側の車上無線機４をそれぞれ停止させるように構成されている。また、列車２が分割する場合に、車上装置３は、列車２が併合分割許可領域内に存在している間は、他の列車２を認識しないように制御するように構成されている。すなわち、列車２が併合分割許可領域内において、分割しようとした場合、車上装置３により、分割した他の列車２を認識してしまうと、非常ブレーキが動作してしまい、列車２の分割を行うことができなくなってしまうため、この分割した他の列車２を認識しないように制御するものである。
Further, when the train 2 is divided, as shown in FIG. 4, each train 2 recognizes in advance the direction in which the train 2 is divided by the on-board device 3. The on-board wireless devices 4 are each stopped. Moreover, when the train 2 divides | segments, the on-board apparatus 3 is comprised so that other trains 2 may not be recognized while the train 2 exists in the merge division division | segmentation permission area | region. In other words, when the train 2 tries to divide within the merge division permitted area, if the on-board device 3 recognizes another divided train 2, the emergency brake operates and the train 2 is divided.
