Description

本発明は、移動閉塞方式に基づき車両を運行する車両交通制御システムに関するものである。   The present invention relates to a vehicle traffic control system for operating a vehicle based on a movement blockage method.

例えば鉄道車両を対象にした車両交通制御システムにおいて、以前は固定閉塞方式と呼ばれる車両運行方式が採用されていた。これは、走行路上に設定された一定区間には一つの列車の存在しか許可せず、他の列車がこの区間に進入するのを禁止する方式である。しかし、この固定閉塞方式では列車間隔の高密度化に対応することができないために、近時は移動閉塞方式と呼ばれる車両運行方式が多く採用されている(例えば特許文献1参照)。   For example, in a vehicle traffic control system for a railway vehicle, a vehicle operation method called a fixed blockage method has been used before. This is a method of allowing only one train to exist in a certain section set on the travel route and prohibiting other trains from entering this section. However, since this fixed blockage method cannot cope with a high density of train intervals, a vehicle operation method called a movement blockage method has recently been adopted (see, for example, Patent Document 1).

図11は、この移動閉塞方式を採用した車両交通制御システムの構成を示す説明図である。この図において、伝送路Lに中央制御装置CC及び路側制御装置SC1,SC2が接続され、更にアンテナATを有する地上通信装置GTM1,GTM2も接続されている。   FIG. 11 is an explanatory diagram showing the configuration of a vehicle traffic control system that employs this movement blockage method. In this figure, a central control device CC and roadside control devices SC1, SC2 are connected to a transmission line L, and ground communication devices GTM1, GTM2 having an antenna AT are also connected.

また、本線SL1の走行路上を車両T1,T2が走行している。これら車両T1,T2は、それぞれ車上制御装置TC1,TC2及び車上通信装置TTM1,TTM2を搭載しており、車上通信装置TTM1,TTM2は地上通信装置GTM1,GTM2との間で無線によるデータの送受信を行うようになっている。   In addition, vehicles T1 and T2 are traveling on the travel path of the main line SL1. These vehicles T1 and T2 are equipped with on-board controllers TC1 and TC2 and on-board communication devices TTM1 and TTM2, respectively. It is designed to send and receive.

そして、駅STを挟んだ本線SL1の対向側に側線SL2が設けられている。この側線SL2は、駅STの両端側に設置されている分岐装置JC1,JC2により本線SL1から分岐されたものである。また、駅STから離れた場所には分岐装置JC3〜JC6が設置されており、これら分岐装置JC3〜JC6を介して本線SL1から引込み線SL3が分岐されている。   A side line SL2 is provided on the opposite side of the main line SL1 across the station ST. The side line SL2 is branched from the main line SL1 by branching devices JC1 and JC2 installed at both ends of the station ST. Further, branching devices JC3 to JC6 are installed at locations away from the station ST, and the service line SL3 is branched from the main line SL1 via these branching devices JC3 to JC6.

路側制御装置SC1,SC2は、それぞれ自己の管轄区間に設置されている分岐装置やその他の機器に対する制御を行うものであり、ここでは破線矢印で示すように路側制御装置SC1が分岐装置JC1,JC2を制御し、路側制御装置SC2が分岐装置JC3〜JC6を制御するようになっている。   The roadside control devices SC1 and SC2 control the branching devices and other devices installed in their own jurisdictions. Here, as indicated by the broken arrows, the roadside control device SC1 has the branching devices JC1 and JC2. The road-side control device SC2 controls the branch devices JC3 to JC6.

中央制御装置CCは、このような路側制御装置SC1,SC2及び車上通信装置TTM1,TTM2から各種情報を収集し、車両運行に関する総合的な管理・制御を行っている。   The central control device CC collects various information from the roadside control devices SC1 and SC2 and the on-board communication devices TTM1 and TTM2, and performs comprehensive management and control related to vehicle operation.

図11に図示した例は、車両T2に関してその尾端側から進行方向に向かう所定区間の距離が走行路専有権設定区間となっている。この走行路専有権設定区間は、車両T2が安全に走行又は停車し続けることができるように設定された区間であり、T2以外の車両がこの区間に進入することは禁止される。   In the example illustrated in FIG. 11, the distance of a predetermined section in the traveling direction from the tail end side with respect to the vehicle T2 is the travel path exclusive right setting section. This travel route exclusive right setting section is a section set so that the vehicle T2 can continue to travel or stop safely, and vehicles other than T2 are prohibited from entering this section.

また、もしこの走行路専有権設定区間内に分岐装置が設置されていれば、この分岐装置もT2以外の車両のために「転換・鎖錠」することは禁止され、この分岐装置の「転換・鎖錠」の状態は車両T2が走行可能な状態に制御される。   In addition, if a branching device is installed in the section for setting the exclusive ownership of the road, this branching device is also prohibited from being “converted / locked” for vehicles other than T2. The state of “lock” is controlled so that the vehicle T2 can travel.

そして、車両T2が進行方向にこの区間内を走行していくにつれて、車両T2の尾端側における走行路専有権の設定は順次解除されていく。つまり、走行路専有権設定区間は車両T2と共にその進行方向に移動していくことになる。
特開2000−108903号公報
Then, as the vehicle T2 travels in this section in the traveling direction, the setting of the exclusive right of the traveling path on the tail end side of the vehicle T2 is sequentially released. That is, the travel route exclusive right setting section moves in the traveling direction together with the vehicle T2.

上述した移動閉塞方式に基づく車両交通制御システムによれば、複雑な連動論理を必要とすることなく安全性を確保することができ、列車間隔の高密度化に対応することができる。しかし、この移動閉塞方式に基づく車両交通制御システムでは、中央制御装置、車上制御装置、及び路側制御装置が有する各機能を実現する手段については、多重化構成としたり、誤り率が所定レベル以下(例えば、10のマイナス6乗以下のレベル)の高価な部品を用いるなど、高信頼性を有する構成とする必要がある。そのため、制御論理が複雑なシステム構成となったり、経済的に不利なシステム構成となり、結果的に充分なコストダウンを図ることが困難であった。   According to the vehicle traffic control system based on the moving block system described above, safety can be ensured without requiring complicated interlocking logic, and it is possible to cope with higher train interval density. However, in the vehicle traffic control system based on this moving block system, the means for realizing each function of the central control device, the on-board control device, and the roadside control device may be a multiplexed configuration, or the error rate is below a predetermined level. It is necessary to have a highly reliable configuration such as using expensive parts (for example, a level of 10 minus 6 or less). Therefore, the control logic has a complicated system configuration or an economically disadvantageous system configuration, and as a result, it has been difficult to achieve a sufficient cost reduction.

本発明は上記事情に鑑みてなされたものであり、制御論理の複雑化及び高価な部品の使用を極力抑制し、もって充分なコストダウンを図ることが可能な車両交通制御システムを提供することを目的としている。   The present invention has been made in view of the above circumstances, and provides a vehicle traffic control system capable of suppressing the complexity of control logic and the use of expensive parts as much as possible, thereby achieving a sufficient cost reduction. It is aimed.

図1は、本発明の第1の実施形態の構成を示すブロック図である。この実施形態に係るシステムは、図示するように、車両速度・位置検出手段1、車両速度・位置制御手段2、車両追跡手段3、ダイヤ管理・制御手段4、進路構成順序制御手段5、車両存在有無確認手段6、走行路等専有権割当要請手段7、走行路等専有権管理手段8、分岐装置制御手段9、及び走行路等専有権解除要請手段10を有している。なお、この第1の実施形態では、中央制御装置、車上制御装置、及び路側制御装置が手段1〜10のうちどの手段を含んで構成されているかについては限定されていない。   FIG. 1 is a block diagram showing the configuration of the first exemplary embodiment of the present invention. As shown in the figure, the system according to this embodiment includes a vehicle speed / position detection means 1, a vehicle speed / position control means 2, a vehicle tracking means 3, a diamond management / control means 4, a course configuration sequence control means 5, a vehicle presence A presence / absence confirmation unit 6, an exclusive right assignment request unit 7 such as a traveling road, an exclusive right management unit 8, a branching device control unit 9, and an exclusive right cancellation request unit 10 such as a traveling road are provided. In the first embodiment, it is not limited as to which of the means 1 to 10 includes the central control device, the on-board control device, and the roadside control device.

そして、本発明では、システムを構成する各手段が有する機能につき、正常動作が阻害された場合に人身事故に直結する蓋然性の高い機能(本明細書ではバイタル(vital)機能と呼ぶことにする)と、そうではない機能(本明細書ではノンバイタル(non-vital)機能と呼ぶことにする)とに分け、バイタル機能を実現する手段については高信頼性を有する構成を付与している。図1に図示した例では、バイタル機能を実現する手段が車両速度・位置検出手段1、車両速度・位置制御手段2、車両存在有無確認手段6、走行路等専有権管理手段8、分岐装置制御手段9、及び走行路等専有権解除要請手段10となっており、これらの手段は2重化構成となっている(これらの手段はそのブロックが2つ重ねられたように図示されている)。   In the present invention, the function of each means constituting the system is a function that has a high probability of being directly connected to a personal accident when normal operation is inhibited (referred to herein as a vital function). It is divided into functions that are not so (referred to as non-vital functions in the present specification), and a means for realizing the vital functions is given a highly reliable configuration. In the example shown in FIG. 1, means for realizing the vital function are vehicle speed / position detection means 1, vehicle speed / position control means 2, vehicle presence / absence confirmation means 6, exclusive property management means 8 such as a traveling path, branching device control, and the like. The means 9 and the exclusive right cancellation request means 10 such as a traveling road, etc., are constructed in a double structure (they are shown as two of the blocks overlapped). .

車両速度・位置検出手段1は、各車両の速度及び位置を検出する手段であり、鉄道列車システムでは車上制御装置側に搭載されているのが通常である(但し、鉄道列車以外のシステム、例えば無人列車システムなどでは中央制御装置側や路側制御装置側に搭載される可能性もある)。この手段の正常動作が阻害されると衝突事故等の人身事故が発生する蓋然性が高くなるため、バイタル機能実現手段として2重化構成になっている。   The vehicle speed / position detection means 1 is a means for detecting the speed and position of each vehicle, and is usually mounted on the on-board controller side in a railroad train system (however, a system other than a railroad train, For example, in an unmanned train system, it may be installed on the central controller side or road side controller side). If the normal operation of this means is hindered, there is a high probability that a personal accident such as a collision accident will occur. Therefore, the vital function realizing means has a double structure.

車両速度・位置制御手段2は、各車両の速度及び位置を制御する手段であり、車両速度・位置検出手段1と同様に、鉄道列車システムでは車上制御装置側に搭載されているのが通常である。この手段もその正常動作が阻害されると衝突事故等の人身事故が発生する蓋然性が高くなるため、バイタル機能実現手段として2重化構成になっている。   The vehicle speed / position control means 2 is a means for controlling the speed and position of each vehicle. Like the vehicle speed / position detection means 1, the vehicle speed / position control means 2 is usually mounted on the on-board controller side in the railway train system. It is. Since this means also has a high probability that a personal accident such as a collision will occur if its normal operation is hindered, it has a double structure as a vital function realization means.

車両追跡手段3は、車両速度・位置検出手段1の検出に基づき、走行路上を走行する全車両について追跡を行い、車両の現在位置を把握する手段である。この手段は、その正常動作が阻害されても直ちに人身事故が発生するわけではないのでノンバイタル機能実現手段である。   The vehicle tracking means 3 is a means for tracking all the vehicles traveling on the traveling road based on the detection of the vehicle speed / position detecting means 1 and grasping the current position of the vehicle. This means is a non-vital function realization means because even if the normal operation is hindered, a personal injury does not occur immediately.

ダイヤ管理・制御手段4は、車両追跡手段3の追跡動作に基づき、車両運行のダイヤを修正するなどダイヤの管理・制御を行う手段である。この手段も、その正常動作が阻害されても直ちに人身事故が発生するわけではないのでノンバイタル機能実現手段に分類される。   The diamond management / control means 4 is a means for managing and controlling the diamond such as correcting the schedule of vehicle operation based on the tracking operation of the vehicle tracking means 3. This means is also classified as a non-vital function realization means because a personal injury does not occur immediately even if the normal operation is hindered.

進路構成順序制御手段5は、共通データベース(図示せず)に格納された線形情報(走行路の勾配・曲線や分岐装置の位置・種別などの情報)やダイヤ管理・制御手段4からの情報に基づいて、車両がどのような順序で何処を走行するかについて決定し、更にこれから車両が通る走行路や分岐装置を抽出する手段である。進路構成順序制御手段5が走行順序を決定するに際しては、シミュレーションによる予測などを利用して効率的な走行順序となるようにする。この進路構成順序制御手段5もノンバイタル機能実現手段に分類される。   The route configuration order control means 5 uses linear information (information such as the gradient / curve of the travel path and the position / type of the branching device) stored in a common database (not shown) and information from the diagram management / control means 4. Based on this, it is a means for determining where and in what order the vehicle travels, and further extracting a travel path and branching device through which the vehicle passes. When the course configuration order control means 5 determines the traveling order, an efficient traveling order is obtained by using prediction by simulation or the like. The course configuration order control means 5 is also classified as a non-vital function realizing means.

車両存在有無確認手段6は、車両速度・位置検出手段1の検出に基づき、走行路上を走行する全車両の存在の有無を確認する手段である。なお、車両存在有無確認手段6は車両速度・位置検出手段1の他に列車の存在を検出する手段があれば、そのような手段に基づく検出情報も併せて利用するのが好ましい。この車両存在有無確認手段6は、正常動作が阻害されて車両存在の有無を確認できなくなった場合は人身事故に直結する蓋然性が高くなるのでバイタル機能実現手段である。そして、もしこの車両存在有無確認手段6が車両を見失った事態が発生した場合には緊急停止装置(図示せず)を作動させるなどして車両運行を停止させる必要がある。   The vehicle presence / absence confirmation means 6 is a means for confirming the presence / absence of all vehicles traveling on the road based on the detection by the vehicle speed / position detection means 1. If the vehicle presence / absence confirmation means 6 has a means for detecting the presence of a train in addition to the vehicle speed / position detection means 1, it is preferable to use detection information based on such means together. This vehicle presence / absence confirmation means 6 is a vital function realization means because when the normal operation is hindered and the presence / absence of the vehicle cannot be confirmed, there is a high probability of being directly connected to a personal accident. If a situation occurs in which the vehicle presence / absence checking means 6 loses sight of the vehicle, it is necessary to stop the vehicle operation by operating an emergency stop device (not shown).

走行路等専有権割当要請手段7は、車両存在有無確認手段6が全車両の存在の有無を確認していることを条件として、進路構成順序制御手段5からの情報に基づき、走行路等が他車両に専有されていなければその専有権の割当要請を行う手段である。ここで、「走行路等」とあるのは走行路の他に分岐装置を含む意味である。この手段はノンバイタル機能実現手段である。走行路等専有権の割当要請が正常に行われなくても直ちに人身事故に直結するわけではないからである。   Based on the information from the course configuration sequence control means 5, the travel path etc. exclusive right assignment request means 7 determines whether the travel road etc. is based on the information that the vehicle presence / absence confirmation means 6 confirms the presence / absence of all vehicles. If it is not owned by another vehicle, it is a means for requesting assignment of the exclusive right. Here, “traveling road etc.” means that a branching device is included in addition to the traveling road. This means is a non-vital function realizing means. This is because even if a request for allocating exclusive rights such as a roadway is not made normally, it does not immediately lead to personal injury.

走行路等専有権管理手段8は、走行路及び分岐装置の専有状態を監視しており、走行路等専有権割当要請手段7から割当要請があった場合には、その割当要請があった車両に対して、他の車両に専有されていないなど専有可能な区間について走行路等専有権を割り当てると共に、分岐装置制御手段9に対してはその車両が走行できるように分岐装置を制御することを指示する手段である。なお、他の車両に専有されていなくても、現在の専有区間と連続でない(つながらない)区間の場合は、専有区間を割り当てることはできない。   The exclusive right management means 8 such as the travel road monitors the exclusive state of the travel road and the branching device, and when there is an assignment request from the exclusive right assignment request means 7 such as the travel road, the vehicle for which the assignment request has been made. On the other hand, the exclusive right such as the driving path is assigned to a section that can be exclusively used, such as not occupied by another vehicle, and the branching device control means 9 is controlled to control the branching device so that the vehicle can travel. It is a means of indicating. In addition, even if it is not exclusively owned by another vehicle, if it is a section that is not continuous (not connected) with the current exclusive section, the exclusive section cannot be assigned.

走行路等専有権管理手段8は、また、走行路等専有権解除要請手段10から走行路等専有権の解除要請があった場合には、それまで車両に対して割り当てていた走行路等専有権の解除を行う。この走行路等専有権管理手段8はバイタル機能実現手段である。   The exclusive right management means 8 such as the traveling road, etc., when the exclusive right cancellation requesting means 10 requests the cancellation of the exclusive right such as the traveling road, etc. Release the right. This exclusive right management means 8 such as a traveling road is a vital function realization means.

分岐装置制御手段9は、走行路等専有権管理手段8からの指示に基づき分岐装置の制御を行い、またその制御状態を走行路等専有権管理手段8に知らせる手段である。分岐装置の制御が正常に行われない場合は人身事故に直結する蓋然性は明らかに高くなるので、この手段はバイタル機能実現手段である。   The branching device control means 9 is means for controlling the branching device based on an instruction from the exclusive right management means 8 for traveling roads and notifying the exclusive state managing means 8 for the control state. If the control of the branching device is not performed normally, the probability of being directly connected to a personal accident is clearly increased, so this means is a vital function realization means.

走行路等専有権解除要請手段10は、車両速度・位置検出手段1、及び進路構成順序制御手段5からの情報に基づき、車両が通過した地点に設定されていた走行路等専有権について解除要請を行う手段である。この解除要請が正常に行われないと他の車両の運行に支障をきたし、人身事故が発生する蓋然性が高くなるので、この手段はバイタル機能実現手段である。   Based on the information from the vehicle speed / position detection means 1 and the course configuration sequence control means 5, the exclusive right cancellation request means 10 for the driving road etc. requests cancellation regarding the exclusive rights such as the driving road set at the point where the vehicle has passed. It is a means to perform. If this cancellation request is not made normally, the operation of other vehicles will be hindered and the possibility of a personal accident occurring will increase, so this means is a vital function realization means.

次に、図1の一般的動作を図9のフローチャートに基づき説明する。まず、車両速度・位置検出手段1が車両速度及び車両位置の検出を行う(ステップ1)。車両追跡手段3は、車両速度・位置検出手段1からの検出信号に基づき、車両追跡を行い現在位置を把握する。また、車両存在有無確認手段6も、車両速度・位置検出手段1からの検出信号に基づき、車両存在の有無を確認する。車両追跡手段3及び車両存在有無確認手段6は、このような車両追跡及び車両存在有無確認を全ての車両について行う(ステップ2)。   Next, the general operation of FIG. 1 will be described based on the flowchart of FIG. First, the vehicle speed / position detecting means 1 detects the vehicle speed and the vehicle position (step 1). The vehicle tracking means 3 performs vehicle tracking based on the detection signal from the vehicle speed / position detection means 1 and grasps the current position. The vehicle presence / absence confirmation unit 6 also confirms the presence / absence of the vehicle based on the detection signal from the vehicle speed / position detection unit 1. The vehicle tracking means 3 and the vehicle presence / absence confirmation means 6 perform such vehicle tracking and vehicle presence / absence confirmation for all the vehicles (step 2).

ダイヤ管理・制御手段4は、車両追跡手段3の追跡結果に基づき、車両運行ダイヤの管理・制御を行い(ステップ3)、更に必要であればダイヤの修正を行う。   The diamond management / control unit 4 manages and controls the vehicle operation diagram based on the tracking result of the vehicle tracking unit 3 (step 3), and further corrects the diamond if necessary.

進路構成順序制御手段5は、ダイヤ管理・制御手段4が管理しているダイヤに基づき、各車両の進路構成すなわち、これから車両が通る走行路や分岐装置を抽出し、各車両の走行順序を設定する(ステップ4)。   The course configuration sequence control means 5 extracts the course configuration of each vehicle, that is, the travel path and branching device through which the vehicle passes based on the schedule managed by the diamond management / control means 4, and sets the travel order of each vehicle. (Step 4).

走行路等専有権割当要請手段7は、進路構成順序制御手段5から各車両の進路構成及び走行順序を入力すると共に、車両存在有無確認手段6から全車両についての存在有無の確認結果を入力し、走行路及び分岐装置について専有権の割当要請を走行路等専有権管理手段8に対して行う(ステップ5)。   An exclusive right assignment requesting means 7 such as a traveling path inputs the course configuration and the traveling order of each vehicle from the course configuration order control means 5 and inputs the confirmation result of the existence of all the vehicles from the vehicle presence / absence confirmation means 6. Then, an exclusive right assignment request for the road and branching device is made to the exclusive right management means 8 such as the road (step 5).

走行路等専有権管理手段8は、走行路及び分岐装置の専有情況の監視を常時行っており、走行路等専有権割当要請手段7から或る車両について走行路及び分岐装置について専有権の割当要請を受けると、他の車両に専有されていなければ要請に係る車両に対して専有権の割当を行う(ステップ6)。   The exclusive right management means 8 such as the traveling road constantly monitors the exclusive situation of the traveling road and the branch device, and the exclusive right assignment request is assigned to the traveling road and the branch device for a certain vehicle from the exclusive right assignment requesting means 7 such as the road. When the request is received, if it is not exclusively owned by another vehicle, the exclusive right is assigned to the requested vehicle (step 6).

そして、割当が行われた分岐装置が車両の走行に合致する方向へ「転換・鎖錠」が行われるよう、走行路等専有権管理手段8は分岐装置制御手段9に対して制御指令を出力する(ステップ7)。これにより、分岐装置制御手段9は分岐装置に対する制御を行い、また、その制御状態を走行路等専有権管理手段8に知らせるようにする。   Then, the exclusive right management means 8 such as the driving path outputs a control command to the branching device control means 9 so that the assigned branching device is “converted / locked” in a direction that matches the traveling of the vehicle. (Step 7). Thereby, the branching device control means 9 controls the branching device, and informs the exclusive right management means 8 such as a traveling path of the control state.

車両速度・位置制御手段2は、車両速度・位置検出手段1から検出信号を入力すると共に、走行路等専有権管理手段8から管理情報を入力しており、更に共通データベース(図示せず)から路線情報や車両性能情報などを入力している。そして、車両速度・位置制御手段2は、これらの信号及び情報から車両の停止目標位置(例えば、走行路等専有権設定区間の終端位置、専有権設定区間内でその車両が走行できる方向に鎖錠されていない分岐装置手前位置、その他安全の確保されていない個所よりも手前側位置のうち最も車両に近い位置など)を演算し、この停止目標位置を超えないように車両の速度及び位置の制御を行う(ステップ8)。   The vehicle speed / position control means 2 receives a detection signal from the vehicle speed / position detection means 1 and also receives management information from the exclusive right management means 8 such as a traveling road, and from a common database (not shown). Route information and vehicle performance information are entered. Then, the vehicle speed / position control means 2 is linked to the stop target position of the vehicle (for example, the terminal position of the exclusive right setting section such as the traveling road, the direction in which the vehicle can travel in the exclusive right setting section from these signals and information. The front position of the unbranched branching device and the position closest to the vehicle among other positions where safety is not ensured are calculated, and the speed and position of the vehicle are set so that this stop target position is not exceeded. Control is performed (step 8).

なお、既述したように、図1の構成は、中央制御装置、車上制御装置、及び路側制御装置が手段1〜10のうちどの手段を含んでいるかについては限定されていないものであるが、後述する図2乃至図4においては、車両速度・位置制御手段2は、車上制御装置側に設ける構成としている。但し、車両速度・位置制御手段2から、停止目標位置を演算する機能の一部又は全部を分離して、中央制御装置側に設けることも可能である。例えば、専有区間終端と未開通分岐装置位置とを比較する機能は中央制御装置側に分担させ、また、未遮断踏切位置等を加味して最終的な停止目標位置を判断する機能は車上制御装置側に分担させる構成なども可能である。これら停止目標位置演算機能の全部を中央制御装置側に設けることも可能であるが、この場合、中央制御装置側の負担は大きくなる。   As described above, the configuration of FIG. 1 is not limited as to which of the means 1 to 10 includes the central control device, the on-board control device, and the roadside control device. 2 to 4 to be described later, the vehicle speed / position control means 2 is provided on the on-board control device side. However, a part or all of the function for calculating the target stop position can be separated from the vehicle speed / position control means 2 and provided on the central controller side. For example, the function of comparing the end of the exclusive section and the position of the unopened branching device is shared by the central control device, and the function of determining the final stop target position taking into account the uninterrupted level crossing position etc. A configuration that is shared by the apparatus side is also possible. It is possible to provide all of these stop target position calculation functions on the central controller side, but in this case, the burden on the central controller side increases.

さて、走行路等専有権解除要請手段10は、車両速度・位置検出手段1、及び進路構成順序制御手段5から運転情況についての情報を入力しており、車両が走行路等専有権設定区間を通過した後は、その走行路等専有権の解除要請を走行路等専有権管理手段8に対して行う(ステップ9)。   Now, the exclusive right cancellation requesting means 10 for the road and the like inputs information about the driving situation from the vehicle speed / position detection means 1 and the course configuration sequence control means 5, and the vehicle sets the exclusive right setting section such as the road and the like. After passing, a request for cancellation of the exclusive right of the traveling road is made to the exclusive right management means 8 of the traveling road (step 9).

走行路等専有権管理手段8は、この解除要請に基づき、車両に割り当てられている走行路等専有権の解除を行う(ステップ10)。   The exclusive right management means 8 such as the traveling road cancels the exclusive right such as the traveling road allocated to the vehicle based on the cancellation request (step 10).

次に、図1の具体的動作、例えば、一旦或る車両に対して割り当てた走行路等専有権を別の車両に対して割り当てる場合の動作につき図10の説明図を参照しつつ説明する。   Next, a specific operation of FIG. 1, for example, an operation in the case of assigning exclusive rights such as a road once assigned to a certain vehicle to another vehicle will be described with reference to the explanatory diagram of FIG.

図10において、本線SL1上を走行中の車両T1は駅STの手前の位置にあり、車両T2は駅STの側線SL2上で停止中である。車両T2は、車両T1が駅STを通過した後に発車予定となっている。したがって、現時点では車両T1に対して尾端側から進行方向に延びる走行路等専有権M1が設定されている。車両追跡手段3は、車両T1,T2の各車両速度・位置検出手段1からの検出信号を入力してそれぞれの現在位置を把握し、追跡結果をダイヤ管理・制御手段4に出力している。   In FIG. 10, the vehicle T1 traveling on the main line SL1 is in a position in front of the station ST, and the vehicle T2 is stopped on the side line SL2 of the station ST. The vehicle T2 is scheduled to depart after the vehicle T1 passes the station ST. Therefore, at present, the exclusive right M1 such as a traveling road extending in the traveling direction from the tail end side is set for the vehicle T1. The vehicle tracking means 3 receives detection signals from the vehicle speed / position detection means 1 of the vehicles T 1 and T 2, grasps the respective current positions, and outputs the tracking results to the diamond management / control means 4.

ところが、車両T1の運行が著しく遅れているため、ダイヤ管理・制御手段4は車両T1の通過前に車両T2を先に発車させるようにダイヤを修正し、進路構成順序制御手段5は、この修正ダイヤに基づき車両T2の発車のために専有させるべき走行路及び分岐装置を抽出したとする。   However, since the operation of the vehicle T1 is remarkably delayed, the diamond management / control unit 4 corrects the diagram so that the vehicle T2 is started first before passing the vehicle T1, and the course configuration sequence control unit 5 It is assumed that a travel path and a branching device to be exclusively used for the departure of the vehicle T2 are extracted based on the diagram.

走行路等専有権割当要請手段7は、この抽出結果に基づき車両T2に対して走行路等専有権M2を割り当てるべきことを走行路等専有権管理手段8に要請する。走行路等専有権管理手段8は、この要請を受けると、現在の走行路及び分岐装置の専有状態を調べ、既に設定してある専有権M1設定区間と、これから設定しようとする専有権M2設定区間との重複部分を抽出する。そして、専有権M1が設定されている車両T1の車両速度・位置制御手段2に対して、重複部分の手前側すなわち分岐装置JC2の手前位置で安全に停止できるか否かを問い合わせる。車両T1側では、この問い合わせに対し、図示しない停止可否判断手段により、分岐装置JC2の手前位置で安全に停止できるか否かの判断を行う。   The travel route exclusive right assignment requesting means 7 requests the travel road exclusive right management means 8 to assign the travel road exclusive power M2 to the vehicle T2 based on the extraction result. Upon receiving this request, the exclusive right management means 8 such as the travel route checks the current exclusive state of the travel route and the branching device, and sets the exclusive right M1 setting section that has already been set and the exclusive right M2 setting to be set in the future. Extract the overlapping part with the section. Then, an inquiry is made to the vehicle speed / position control means 2 of the vehicle T1 for which the exclusive right M1 is set as to whether or not the vehicle can be safely stopped at the front side of the overlapping portion, that is, the front side of the branching device JC2. In response to this inquiry, the vehicle T1 side determines whether or not it can be safely stopped at a position in front of the branching device JC2 by a stop propriety determination unit (not shown).

車両T1から分岐装置JC2の手前位置で停止できない旨の回答が返ってきた場合、走行路等専有権管理手段8は走行路等専有権割当要請手段7からの専有権M2の割当要請を却下し、そのまま車両T1に専有権M1を保持させて車両T1が通過するのを待つようにする。   When the vehicle T1 returns a response indicating that the vehicle cannot be stopped at the position before the branching device JC2, the exclusive right management means 8 such as the traveling road rejects the allocation request for the exclusive right M2 from the exclusive right allocation requesting means 7 such as the traveling road. Then, the exclusive right M1 is held in the vehicle T1, and the vehicle T1 is waited for to pass.

一方、車両T1から分岐装置JC2の手前位置で安全に停止できる旨の回答が返ってきた場合(車両T1はこの回答を走行路等専有権管理手段8及び走行路等専有権解除要請手段10の双方に送っている)、走行路等専有権管理手段8には専有権M1の解除要請が走行路等専有権解除要請手段10から送られてくるので、走行路等専有権管理手段8はこの専有権M1の解除要請を許可する。そして、走行路等専有権管理手段8は、走行路等専有権割当要請手段7からの車両T2に対する専有権M2の割当要請を許可し、車両T2が通行できるように分岐装置JC2を制御すべきことを分岐装置制御手段9に指令する。これにより、車両T2の専有権M2が側線SL2上及び本線SL1上に設定され、車両T2は駅STから発車して安全に走行できるようになる。   On the other hand, when an answer indicating that the vehicle T1 can be stopped safely at the position before the branching device JC2 is returned from the vehicle T1 (the vehicle T1 sends the answer to the exclusive right management means 8 such as the road and the exclusive right cancellation request means 10 such as the road) Since the request for canceling the exclusive right M1 is sent from the exclusive right cancellation requesting means 10 to the traveling road etc., the exclusive right management means 8 Permit the request to cancel exclusive right M1. Then, the exclusive right management means 8 such as the traveling road should permit the allocation request of the exclusive right M2 to the vehicle T2 from the exclusive right allocation requesting means 7 such as the traveling road and control the branching device JC2 so that the vehicle T2 can pass. To the branching device control means 9. As a result, the exclusive right M2 of the vehicle T2 is set on the side line SL2 and the main line SL1, and the vehicle T2 departs from the station ST and can travel safely.

上述した図1の構成では、移動閉塞方式の機能を実現する全ての手段に対して高信頼性を有する構成を付与しているわけではなく、バイタル機能を実現する手段に対してのみ、つまり正常動作が阻害された場合に人身事故に直結する蓋然性の高い重要な機能を実現する手段に対してのみ、高信頼性を有する構成を付与しているので、制御論理の複雑化や高価な部品の使用を極力抑制することができる。したがって、充分なコストダウンを図ることができるようになる。これに対し、従来技術では、図1の全ての手段1〜10に対して高信頼性を有する構成を付与していたため、充分なコストダウンを図ることができなかった。   In the configuration of FIG. 1 described above, a configuration having high reliability is not given to all means for realizing the function of the movement blocking method, but only for the means for realizing the vital function, that is, normal. A highly reliable configuration is given only to a means that realizes an important function that has a high probability of being directly connected to a human accident when the operation is hindered, so that the control logic is complicated and expensive parts are used. Can be suppressed as much as possible. Therefore, a sufficient cost reduction can be achieved. On the other hand, in the prior art, since all the means 1 to 10 shown in FIG. 1 are provided with a highly reliable configuration, it has not been possible to achieve a sufficient cost reduction.

なお、図1の構成例は、バイタル機能を実現する手段に対しては2重化構成とすることにより高信頼性を付与しているが、3重化以上の多重化構成とすることが可能である。また、誤り率が所定レベル以下(例えば、10のマイナス6乗以下のレベル)の高価な部品を用いることにより高信頼性を確保するようにしてもよい。   In the configuration example of FIG. 1, high reliability is given to the means for realizing the vital function by adopting a duplex configuration, but it is possible to have a multiplexed configuration of triple or more. It is. Further, high reliability may be ensured by using an expensive part having an error rate of a predetermined level or less (for example, a level of 10 to the sixth power or less).

図2は本発明の第2の実施形態の構成を示すブロック図である。この実施形態は、図1における各手段が帰属する制御装置を限定したものである。すなわち、中央制御装置CCは、車両追跡手段3、ダイヤ管理・制御手段4、進路構成順序制御手段5、車両存在有無確認手段6、走行路等専有権割当要請手段7、走行路等専有権管理手段8、及び走行路等専有権解除要請手段10を含んでおり、車上制御装置TCは、車両速度・位置検出手段1及び車両速度・位置制御手段2を含んでおり、路側制御装置SCは分岐装置制御手段9を含んでいる。そして、中央制御装置CC、車上制御装置TC、路側制御装置SC間では伝送装置TMを介して各種データの授受が行われている。   FIG. 2 is a block diagram showing the configuration of the second exemplary embodiment of the present invention. This embodiment limits the control apparatus to which each means in FIG. 1 belongs. That is, the central control unit CC includes the vehicle tracking means 3, the schedule management / control means 4, the route configuration order control means 5, the vehicle presence / absence confirmation means 6, the exclusive ownership assignment requesting means 7 such as the traveling road, and the exclusive rights management such as the traveling road. The vehicle control device TC includes a vehicle speed / position detection unit 1 and a vehicle speed / position control unit 2, and the road side control device SC includes Branch device control means 9 is included. Various data is exchanged between the central control device CC, the on-board control device TC, and the roadside control device SC via the transmission device TM.

この第2の実施形態によれば、主要な手段の多くが中央制御装置CCに含まれているので、メインテナンスが容易となり、保守コストを低減できるというメリットが得られる。   According to the second embodiment, since many of the main means are included in the central control unit CC, there are advantages that maintenance is facilitated and maintenance costs can be reduced.

図3は本発明の第3の実施形態の構成を示すブロック図である。この実施形態は、第2の実施形態の変形例である。すなわち、図2では走行路等専有権解除要請手段10が中央制御装置CCに含まれていたが、図3では走行路等専有権解除要請手段10が車上制御装置TCに含まれている。この実施形態では、走行路等専有権の解除についての演算を中央制御装置CCで行う必要がないので、その分だけ中央制御装置CCの負担を軽減することができ、中央制御装置CCの運用効率を高めることができる。   FIG. 3 is a block diagram showing the configuration of the third exemplary embodiment of the present invention. This embodiment is a modification of the second embodiment. That is, in FIG. 2, the exclusive right cancellation requesting means 10 for the road and the like is included in the central controller CC, but in FIG. 3, the exclusive right cancellation request means 10 for the road and the like is included in the on-board controller TC. In this embodiment, since it is not necessary for the central controller CC to perform the calculation for releasing the exclusive right such as the traveling road, the burden on the central controller CC can be reduced accordingly, and the operation efficiency of the central controller CC can be reduced. Can be increased.

図4は本発明の第4の実施形態の構成を示すブロック図である。この実施形態は、第3の実施形態の変形例である。すなわち、図3では走行路等専有権割当要請手段7が中央制御装置CCに含まれていたが、図4では走行路等専有権割当要請手段7が車上制御装置TCに含まれている。この実施形態では、走行路等専有権の割当についての演算を中央制御装置CCで行う必要がないので、その分だけ中央制御装置CCの負担を軽減することができ、第3の実施形態よりも一層中央制御装置CCの運用効率を高めることができる。   FIG. 4 is a block diagram showing the configuration of the fourth exemplary embodiment of the present invention. This embodiment is a modification of the third embodiment. That is, in FIG. 3, the exclusive right assignment requesting means 7 for the road and the like is included in the central controller CC, but in FIG. 4, the exclusive right assignment request means 7 for the road and the like is included in the on-board controller TC. In this embodiment, since it is not necessary for the central control device CC to perform computations regarding the assignment of exclusive rights such as traveling roads, the burden on the central control device CC can be reduced by that much, and compared to the third embodiment. The operational efficiency of the central controller CC can be further increased.

図5は本発明の第5の実施形態の構成を示すブロック図である。この実施形態は、図1の第1の実施形態における走行路等専有権割当要請手段7を走行路専有権割当要請手段7A及び分岐装置専有権割当要請手段7Bに分割すると共に、走行路等専有権管理手段8を走行路専有権管理手段8A及び分岐装置専有権管理手段8Bに分割し、各手段が分担する機能の範囲を明確に区分したものである。なお、走行路等専有権解除要請手段10については、走行路に関する機能と分岐装置に関する機能とに分けることはせず、そのままにしている。割当と異なり、解除の場合は分けるメリットに乏しいからである。この第5の実施形態の動作は、既述した第1の実施形態の動作から容易に類推することができるのでその説明については省略する。   FIG. 5 is a block diagram showing the configuration of the fifth exemplary embodiment of the present invention. This embodiment divides the road exclusive right allocation requesting means 7 in the first embodiment of FIG. 1 into a road exclusive right allocation requesting means 7A and a branching apparatus exclusive right allocation requesting means 7B, and the road exclusive The right management means 8 is divided into a travel path exclusive right management means 8A and a branch device exclusive right management means 8B, and the range of functions shared by each means is clearly divided. Note that the exclusive right cancellation requesting means 10 such as the traveling road is not divided into a function relating to the traveling road and a function relating to the branching device, and is left as it is. This is because, unlike allocation, there is little merit in dividing in the case of cancellation. Since the operation of the fifth embodiment can be easily inferred from the operation of the first embodiment described above, the description thereof is omitted.

図6は本発明の第6の実施形態の構成を示すブロック図である。この実施形態は、図5における各手段が帰属する制御装置を限定したものである。すなわち、中央制御装置CCは、車両追跡手段3、ダイヤ管理・制御手段4、進路構成順序制御手段5、車両存在有無確認手段6、走行路専有権割当要請手段7A、分岐装置専有権割当要請手段7B、走行路専有権管理手段8A、及び走行路等専有権解除要請手段10を含んでおり、車上制御装置TCは、車両速度・位置検出手段1及び車両速度・位置制御手段2を含んでおり、路側制御装置SCは、分岐装置専有権管理手段8B及び分岐装置制御手段9を含んでいる。そして、中央制御装置CC、車上制御装置TC、路側制御装置SC間では伝送装置TMを介して各種データの授受が行われている。   FIG. 6 is a block diagram showing the configuration of the sixth embodiment of the present invention. This embodiment limits the control device to which each means in FIG. 5 belongs. That is, the central control unit CC includes a vehicle tracking unit 3, a schedule management / control unit 4, a route configuration sequence control unit 5, a vehicle presence / absence confirmation unit 6, a travel route exclusive right allocation request unit 7A, and a branching unit exclusive right allocation request unit. 7B, a traveling road exclusive right management means 8A, and a traveling road exclusive right release requesting means 10 are included. The on-board controller TC includes a vehicle speed / position detecting means 1 and a vehicle speed / position controlling means 2. The roadside control device SC includes a branching device exclusive right management means 8B and a branching device control means 9. Various data is exchanged between the central control device CC, the on-board control device TC, and the roadside control device SC via the transmission device TM.

この第6の実施形態によれば、主要な手段の多くが中央制御装置CCに含まれているので、メインテナンスが容易となり、保守コストを低減できるというメリットが得られる。 According to the sixth embodiment , since many of the main means are included in the central control unit CC, there are advantages that maintenance is facilitated and maintenance costs can be reduced.

図7は本発明の第7の実施形態の構成を示すブロック図である。この実施形態は、第6の実施形態の変形例である。すなわち、図6では走行路等専有権解除要請手段10が中央制御装置CCに含まれていたが、図7では走行路等専有権解除要請手段10が車上制御装置TCに含まれている。この実施形態では、走行路等専有権の解除についての演算を中央制御装置CCで行う必要がないので、その分だけ中央制御装置CCの負担を軽減することができ、中央制御装置CCの運用効率を高めることができる。   FIG. 7 is a block diagram showing the configuration of the seventh exemplary embodiment of the present invention. This embodiment is a modification of the sixth embodiment. That is, in FIG. 6, the exclusive right cancellation requesting means 10 for the road and the like is included in the central controller CC, but in FIG. 7, the exclusive right cancellation request means 10 for the road and the like is included in the on-board controller TC. In this embodiment, since it is not necessary for the central controller CC to perform the calculation for releasing the exclusive right such as the traveling road, the burden on the central controller CC can be reduced accordingly, and the operation efficiency of the central controller CC can be reduced. Can be increased.

図8は本発明の第8の実施形態の構成を示すブロック図である。この実施形態は、第7の実施形態の変形例である。すなわち、図7では分岐装置専有権割当要請手段7Bが中央制御装置CCに含まれていたが、図8では分岐装置専有権割当要請手段7Bが車上制御装置TCに含まれている。この実施形態では、分岐装置専有権の割当についての演算を中央制御装置CCで行う必要がないので、その分だけ中央制御装置CCの負担を軽減することができ、第7の実施形態よりも一層中央制御装置CCの運用効率を高めることができる。更に、図8では走行路専有権割当要請手段7Aが中央制御装置CCに残っているが、これについても車上制御装置TCに含ませる構成とし、より一層中央制御装置CCの運用効率を高めることも可能である。   FIG. 8 is a block diagram showing the configuration of the eighth embodiment of the present invention. This embodiment is a modification of the seventh embodiment. That is, in FIG. 7, the branching device exclusive right assignment requesting means 7B is included in the central controller CC, but in FIG. 8, the branching device exclusive right assignment requesting means 7B is included in the on-board control device TC. In this embodiment, since it is not necessary for the central control device CC to perform the calculation for the branch device exclusive right assignment, the burden on the central control device CC can be reduced by that amount, which is much higher than in the seventh embodiment. The operational efficiency of the central controller CC can be increased. Further, in FIG. 8, the travel route exclusive right allocation requesting means 7A remains in the central control unit CC, but this is also included in the on-board control unit TC to further improve the operation efficiency of the central control unit CC. Is also possible.

なお、各手段の中央制御装置CC、車上制御装置TC、及び路側制御装置SCに対する振り分け方は、上記の図2〜図4、及び図6〜図8に示した例に限定されず、適宜変更することが可能である。   In addition, how to distribute each means with respect to the central control device CC, the on-board control device TC, and the roadside control device SC is not limited to the examples shown in FIGS. 2 to 4 and FIGS.
