これらの表において、「２１ロＴ」、「２１イＴ」等は転てつ機２１イ、２１ロそれぞれに至るあるいはそれぞれから出る線路区間を表わしている。そして、１ＲＡ、１ＲＢ等は、転てつ機が作動して、あるいは復帰して上述した着点Ａ、Ｂ等に至る進路が確立されたこと（つまり、鎖錠されたこと）を意味している。
【００１８】
次の表３及び表４は、列車追跡のための列車登録テーブルを表している。
【００１９】

そして表５及び表６は列車追跡テーブルを示している。

図２、表１、図４は複線下り（Ｒ）の例、図３、表２、図５は単線の例を示している。
【００２１】
この実施の形態の踏切制御システムは、踏切の警報制御区間を警報の開始点、終了点及び過走監視区間までを連続的な列車の在線検知センサの列で表現した踏切制御表１を記憶している記憶部２と、踏切の遮断機、警報器、踏切制御子等から構成される踏切現場機器３と、列車の在線を検知する在線検知センサ４と、駅の進路を制御する電子連動装置５と、踏切制御表１の指示に従って踏切現場機器３を制御し、また検知するセンサ４の出力、転てつ器の開通方向、記憶部２に予め入力され記憶されている線路の配線図及び列車の進路の情報から列車の本数、列車の在線位置と列車の進行方向を演算し、演算した列車の情報及び電子連動装置５からの信号機や進路鎖錠の情報に基づき、踏切制御表１の指示に従って列車毎に踏切現場機器３の中の警報器を制御する踏切制御装置７から構成される。
【００２２】
踏切制御装置７は保安器であるので、電子連動装置５と同様にフェールセーフな制御用のコンピュータを用いている。記憶部２に登録する線形図や制御表のデータは、パソコン８を用いる。踏切現場機器３には、遮断器を制御する装置や警報器、また列車の在線を検出する軌道回路、始動点制御子、終止点制御子などから構成されている。
【００２３】
この実施の形態の踏切制御システムの動作は、次の通りである。
【００２４】
表１のＡ踏切制御表において「進路名」欄には関連する進路名、「警報制御」欄には始動条件、終止条件、そして「過走監視区間」欄には過走監視区間が記載されている。記載されたこれらの条件は、図２の線形図上では上り／下り別に連続した区間（警報制御区間）に表現されている。
【００２５】
警報制御区間の在線検知センサ４が最初に動作した時点で、列車の進入認識を行い、認識番号の発行を行う。以後センサ４の動きに合わせて、列車の先頭の位置と後尾の位置を追跡する。そして列車の位置と進路の信号により、警報を制御する。
【００２６】
例えば、Ａ踏切に関連する図２の線形図、表１の踏切制御表において、先行列車１−１が場内信号に従って構内に進行中で、第１内方の軌道回路の位置（サブセクション１−▲１▼，１−▲２▼。つまり、セクション１の踏切制御子Ａ（閉電路型）より右方。このセクションについては図４、表５を参照）に在線する時には、先行列車１−１は踏切Ａを警報中にしている。この時点で、後続列車１−２が、セクション１の制御子Ａの位置に進入してきた場合、場内信号機１ＲＡ，１ＲＢが共に停止現示の場合は、後続列車１−２は場内には進行できないので、後続列車の場内進入によるＡ踏切の警報をする必要はなく、後続列車１−２に対する警報制御は行わない。
【００２７】
さらに具体的に説明する。表１に示すように、踏切制御表は警報制御すべき内容が各行単位に整理、指示されている。その内容は次のようなものである。
【００２８】
ａ．方向：上り／下り
ｂ．区分：進入、通過、進出
ｃ．進路番号：１ＲＡ（○○方―下り１番線）、１ＲＢ（○○方―下り本線）
ｄ．始動条件：Ａ ２１イＴ但 １ＲＡ、 Ａ但 １ＲＢ
ｅ．警報終止条件：Ｃ 但 ２１ロＴ、 Ｆ但 ２１イＴ
ｆ．過走終止条件：
ｇ．過走監視区間：
踏切Ａに対する警報制御動作は、次の通りである。警報には上りの警報と下りの警報があるが、ここでは下りの警報について説明する。
【００２９】
(ｉ)列車１−１が先ず、セクション１に進行してくると、セクション１の列車の在線検知センサ４が動作し、列車１−１が認識され、表３の列車登録テーブルと表５の列車追跡テーブルに認識番号１−１が登録され、列車追跡テーブルの在線位置情報に位置が登録される。
【００３０】
列車１−１がセクション１に進入後、制御子Ａまで進行して来ると、区分が▲１▼から▲２▼に移り、列車追跡テーブルの内容は表５の列車１−１（ａ）の欄の内容となる。
【００３１】
(ii)列車１−１の在線位置と電子連動装置５から入力した進路の設定状態の情報と、入力された進路に対応する表１の下り方向の制御指示にしたがって、警報開始・終止制御を行う。
【００３２】
いま列車１−１は、１行目の進路番号の欄により着点Ａへの下り進路１ＲＡが鎖錠されていて（つまり、１ＲＡとなっていて）、セクション１−▲２▼からセクション３−▲２▼までの間のいずれかに在線している場合に警報を始動するが、２行目の指示では１ＲＢの進路が鎖錠されていないので、警報の開始は必要ない。
【００３３】
いずれかの行の条件が成立すれば警報動作を行うので、このケースでは１行目の指示により、下り方向の警報動作を行う。
【００３４】
( iii)列車１−１がさらに進行して、セクション３に進入完了した時点で（表５の列車１−１（ｃ）の欄）、続行列車１−２がセクション１−▲２▼に進入してきた場合（表５の列車１−２（ｃ）の欄）、列車１−１は前項(ii)に従って警報動作を行っているが、列車１−２に対しては、電子連動装置５からの情報により、以下の制御を行う。
【００３５】
（ア）転てつ器２１イ、２１ロが反位方向に開通している場合は、１ＲＢの進路（つまり、下り本線の着点Ｂへの進路）は列車１−１が前に居るので、未だ設定されておらず、警報動作はしない。
【００３６】
（イ）転てつ器２１イ、２１ロが定位方向に開通している場合で、１ＲＢの進路が鎖錠されている場合（つまり、１ＲＢの場合）は、制御表の２行目の警報始動条件が成立するので、警報を開始する。
【００３７】
(iv)下り１番線の列車１−１による踏切Ａの警報は、列車１−１がＡ踏切を通過して踏切制御子Ｃを作動させると停止することになる。
【００３８】
(ｖ)列車１−２については、２１イＴに在線し、踏切制御子Ｆを作動させたときに警報を停止させる。
【００３９】
以上の警報制御処理の流れが図６に示してある。電子連動装置５からの情報と列車在線検知情報から列車１−１の在線を追跡し（ステップ１０１，１０２）、制御表に基づいて警報制御の演算処理を行ない、警報始動条件が成立すれば警報出力を指示する（ステップ１０３，１０４）。
【００４０】
また電子連動装置５からの情報と列車在線検知情報から列車１−２の在線を追跡し（ステップ１０１，１０５）、制御表に基づいて警報制御の演算処理を行ない、警報始動条件が成立すれば警報出力を指示する（ステップ１０６，１０７）。そして踏切現場機器３への警報出力は、全列車の警報出力のＯＲで出力する（ステップ１０８，１０９）。
【００４１】
このようにして、列車毎に警報制御することにより、例えば、始動点制御子Ａから踏切までに警報遅延のタイマをかける場合でも、列車毎に、さらには進路毎に（列車が１ＲＡの進路か１ＲＢの進路か）タイマを持つことができるので、警報時間を最適に制御することができる。
【００４２】
なお、踏切制御装置７は電子連動装置５に組み込むことができる。すなわち、ハードウェアとしては電子連動装置５のみとし、これに上記の機能を実行するソフトウェアを組み込むことによって、電子連動装置５と一体型の踏切制御装置とすることができる。
【００４３】
また、駅の構内に複数の踏切がある場合、踏切毎に表１の踏切制御表、図４の列車追跡セクション、表３の列車登録テーブル、表５の列車追跡テーブルと追跡セクション定義テーブルを作成することで、複数の踏切を制御することができる。また、一つの踏切で異なる線区がある場合でも、同様の考えで対応できる。
【００４４】
次に、単線区間に適用した場合の動作について説明する。表２に示したように、下り本線に停止している列車が出発する際には、表２のＢ踏切制御表に基づき、１行目の指示に従い、列車が下り本線４ＲＴに在線していて、着点Ｎへの進路ＲＮが鎖錠されていること（４ＲＮ）であれば、その列車が１ＲＡＴ〜３２イＴの間のどこに在線していても警報器を作動させる。そして、列車がＢ踏切を下り方向に通過し、制御子Ｃを作動させると踏切警報を停止する。
【００４５】
逆に、上り列車については、表２の２行目の条件に基づき、上り列車が４ＲＴに在線し、制御子Ａを作動させれば踏切制御を行い、制御子Ｃを通過したところで踏切制御を停止する。ただし、この場合には上り列車はＢ踏切を通過する前に踏切制御を停止することになるが、実運営では制御子Ｃの作動後、所定の時間が経過して時点で停止させる設定にしていて問題はない。
【００４６】
そして、これらの踏切制御において、列車の上り、下りの方向を判断するために、次のような判断手順を取っている。図４及び図５に示すように、セクション番号は上り（左：Ｌ）から下り（右：Ｒ）に昇順に指定する。これにより、表５及び表６の列車の追跡テーブルに位置を更新する時点で、セクション番号をチェックすることで上りか下りかを判定することができる。例えば、サブセクション３−▲１▼に進入を検知し、在線在りを登録する際に、セクション２に在線在りの場合はセクション２からセクション３への昇順の進入として、下り方向に進行したと判定し、方向欄に下りを登録する。
【００４７】
逆にサブセクション３−▲２▼を列車が進出した場合に、セクション２に在線在りの場合は、列車はセクション番号が降順となり、上りとなり、後退したと見なす。
【００４８】
単線区間においては、出側の始動点制御子が在線を検知した時に、列車の方向を判断して、入り側であれば警報を開始し、出側であれば警報不要の判断を行う必要がある。
【００４９】
従来は、方向を確定するために方向検知用の制御子を設置し、事前に出側の列車を予測して、出側始動点が列車を検知した時に、警報をマスクする機能を一般的に採用していた。しかし本実施の形態では、列車の在線情報を追跡することで、安全に確実に列車の方向を判断する。
【００５０】
例えば、表６に示すように、図３で制御子Ａが列車の在線を検知した場合、列車２−１がサブセクション７−▲３▼に在線しており、セクション４，６を通過して来ていれば、確実に下り列車だと判断でき、警報を開始しない。
【００５１】
また図５で、制御子Ａが列車の在線を検知した場合に、列車が存在しないか、存在してもサブセクション７−▲３▼に位置を持つ列車が居ない場合は、下り列車とは判断せずに上り列車と判断して、新しく上りの列車の認識番号２−１を発行、登録し、警報を開始すると同時に、以後、列車追跡を行う。
【００５２】
このように本実施の形態では、列車を１台ずつ位置追跡することで、列車毎に踏切を警報するかしないか、警報する場合にはどのタイミングで警報すべきかを制御することができるので、無駄な警報をなくして最適な踏切警報制御を行うことができる。
【００５３】
【発明の効果】
本発明は列車を主体として、列車毎に、列車の先頭位置と後尾の位置を点としてではなく、線として連続的に追跡し、列車の進行方向を把握して、踏切の警報制御を行うことにより、列車別にタイマーを持つことができるようになり、正確で、安全で、警報時間を最適にした制御が可能となる。
【００５４】
また列車毎に警報制御することにより、続行列車による不要な警報を防止することができる。さらに進行方向を自動的に検出できるので、方向検知用の制御子を別途設置する必要がない。

[0002]
[Prior art]
In a conventional railroad crossing control device, the presence / absence detection sensor of the train detects whether a train is present or not, and controls a railroad crossing warning based on the detection output.
[0003]
[Problems to be solved by the invention]
In such a conventional level crossing control device, there is no problem when there is one train in the alarm control section, but when there are a plurality of trains, the preceding train and the following train cannot be distinguished. In some cases, the alarm time may be unnecessarily increased in order to output an alarm from the detection of the preceding train until the subsequent train is no longer detected.
[0004]
The present invention has been made in view of such a conventional problem. By distinguishing the preceding train and the following train and providing the information of alarm control for each train, the alarm time of the railroad crossing becomes unnecessarily long.

It is divided into three categories of knowledge, detection, and advance (detected), and the train position in each of the plurality of sections is determined to belong to any of the three categories of undetected, detected, or advanced, and the determination result, transfer The train registration table for registering the train number to be monitored for each level crossing from the information of the opening direction of the lever, the wiring diagram of the train that has been input and stored in advance and the route of the train, and for each train number to be monitored A train section definition table and a train tracking table for sequentially registering the result of determining whether the position of the train in each of the plurality of sections belongs to any of the three categories of undetected, detected, or advanced, create the train registration table and with reference to the train section definition table train tracking table calculates the number of trains, the traveling direction of the rail position and the train of the train, information of the calculated train And based on information from the interlocking device, it is characterized in that the alarm control the crossing field apparatus for each train and for each route according to the instructions of the crossing control table.
[0006]
In the level crossing control device according to the first aspect of the present invention, the level crossing alarm control section is expressed in the train crossing control table as a continuous train on-line detection sensor sequence including the alarm start point, end point and overrun monitoring section. The control device determines whether the position of the train in each of the plurality of sections belongs to any of the three categories of undetected, detected, or advanced based on the outputs of the presence detection sensor and the level crossing controller. The train registration table for registering the train number to be monitored for each level crossing, from the train route information and the train route information entered and stored in advance, and multiple sections for each train number to be monitored Create a train section definition table and a train tracking table that sequentially register the results of determining whether the train position in each of the three categories of undetected, detected, or advanced The train registration table and train section definition table train by referring to the number of trains in the tracking table, calculates the moving direction of the rail position and the train of the train, the traffic and route locking from the information and the interlocking device of the calculated train Based on the information, the railway crossing field device is subjected to alarm control for each train according to the instructions in the crossing control table.
[0007]
In this way, even when multiple trains are on the same alarm control section, individual trains are distinguished and the level crossing alarm is controlled individually corresponding to them, and it is not possible to distinguish between the preceding train and the following train as in the past. Therefore, the alarm time is optimally controlled so as not to cause a situation in which it is erroneously recognized as one long train and the level crossing alarm becomes long.
[0008]
According to a second aspect of the present invention, in the crossing control apparatus according to the first aspect, the interlocking device includes the alarm control device, and the crossing alarm control is performed by software using the same hardware as the electronic interlocking device.
[0009]
According to a third aspect of the present invention, in the crossing control device according to the first or second aspect, the alarm control device recognizes a train for each level crossing when there are a plurality of level crossings in the premises, that is, the same train as the system Is recognized as a plurality of trains corresponding to the number of railroad crossings, tracked, and alarm-controlled. Even when there are a plurality of railroad crossings in the station, alarm control is performed for each railroad crossing.
[0010]
According to a fourth aspect of the present invention, in the crossing control device according to the first or second aspect, the warning control device performs warning control of a single line section using information on the direction in the calculated train information. By tracking the on-line information of the train, the direction of travel is correctly determined and alarm control is performed, thereby eliminating unnecessary level crossing alarms.
[0011]
According to a fifth aspect of the present invention, in the railroad crossing control device according to the first or second aspect, when the alarm control device tracks a train, the section number is assigned so that the tracking section is always in ascending order from the upward direction to the downward direction. Thus, it is possible to accurately determine the up / down direction of the train.
[0014]

[0021]
The railroad crossing control system according to this embodiment stores a railroad crossing control table 1 in which the alarm control section of a railroad crossing is expressed by a row of continuous on-line detection sensors up to the alarm start point, end point, and overrun monitoring section. A storage section 2, a railroad crossing breaker, an alarm device, a railroad crossing controller 3, etc., a track detection sensor 4 that detects the presence of a train, and an electronic interlocking device that controls the course of the station 5 and control of the level crossing field device 3 according to the instructions in the level crossing control table 1, and the output of the sensor 4 to be detected, the opening direction of the switch, the wiring diagram of the line previously input and stored in the storage unit 2, and Based on the train route information, the number of trains, the train position and the traveling direction of the train are calculated, and based on the calculated train information and information on traffic lights and route locks from the electronic interlocking device 5, Follow the instructions for each level crossing site equipment 3 for each train Composed of crossing controller 7 for controlling the alarm device.
[0022]
Since the railroad crossing control device 7 is a protector, a fail-safe control computer is used in the same manner as the electronic interlocking device 5. The personal computer 8 is used as the linear diagram and control table data to be registered in the storage unit 2. The railroad crossing site equipment 3 includes a device that controls a circuit breaker, an alarm, a track circuit that detects the presence of a train, a start point controller, a stop point controller, and the like.
[0023]
The operation of the level crossing control system of this embodiment is as follows.
[0024]
In the A level crossing control table of Table 1, the "Course name" column contains the relevant course name, the "Alarm control" column shows the start condition, the stop condition, and the "Overrun monitoring section" column contains the overrun monitoring section. ing. These described conditions are expressed in a continuous section (alarm control section) for each up / down in the linear diagram of FIG.
[0025]
When the on-line detection sensor 4 in the alarm control section operates for the first time, train entry recognition is performed and an identification number is issued. Thereafter, the head position and the tail position of the train are tracked in accordance with the movement of the sensor 4. The alarm is controlled by the train position and route signal.
[0026]
For example, in the linear diagram of FIG. 2 related to the level crossing A and the level crossing control table of Table 1, the preceding train 1-1 is proceeding on the premises according to the in-field signal, and the position of the first inner track circuit (subsection 1- (1), 1- (2), that is, to the right of the level crossing controller A (closed circuit type) in section 1. For this section, refer to FIG. Keeps level crossing A in alarm. At this time, if the following train 1-2 has entered the position of the controller A in section 1, if both the on-site traffic lights 1RA and 1RB are stopped, the following train 1-2 cannot proceed into the field. Therefore, it is not necessary to issue a warning of the level crossing A due to the approach of the following train in the field, and the warning control for the following train 1-2 is not performed.
[0027]
This will be described more specifically. As shown in Table 1, in the level crossing control table, contents to be subjected to alarm control are arranged and instructed for each line. The contents are as follows.
[0028]
a. Direction: Up / Down b. Classification: entry, passage, advance c. Route number: 1RA (XX direction-down line 1), 1RB (XX direction-main line)
d. Starting condition: A 21 It T However 1RA , A However 1RB
e. Alarm termination condition: C but 21 Lo T, F but 21 It T
f. Overrun termination condition:
g. Overrun monitoring section:
The alarm control operation for the crossing A is as follows. There are two types of alarms: an upstream alarm and a downstream alarm. Here, the downstream alarm will be described.
[0029]
(i) When the train 1-1 first proceeds to section 1, the on-line detection sensor 4 of the train in section 1 operates to recognize the train 1-1, and the train registration table in Table 3 and Table 5 The identification number 1-1 is registered in the train tracking table, and the position is registered in the on-line position information of the train tracking table.
[0030]
When train 1-1 enters section 1 and proceeds to controller A, the section changes from (1) to (2), and the contents of the train tracking table are as shown in Table 5 for train 1-1 (a). It becomes the contents of the column.
[0031]
(ii) The alarm start / stop control is performed in accordance with the information on the on-line position of the train 1-1 and the route setting state information input from the electronic interlocking device 5 and the downward control instruction in Table 1 corresponding to the input route. Do.
[0032]
The train 1-1 now has its downward route 1RA to the landing point A locked by the column of the route number in the first row (that is, 1RA ). From section 1- (2) to section 3- The alarm is started when the line is located anywhere between (2). However, since the route of 1 RB is not locked by the instruction on the second line, it is not necessary to start the alarm.
[0033]
Since the alarm operation is performed when the condition of any row is satisfied, in this case, the alarm operation in the downward direction is performed according to the instruction on the first row.
[0034]
(iii) When train 1-1 further progresses and completes entry into section 3 (column of train 1-1 (c) in Table 5), continued train 1-2 enters section 1- (2) Train 1-2 is performing an alarm operation according to the preceding paragraph (ii), but for the train 1-2 from the electronic interlocking device 5 The following control is performed based on the information.
[0035]
(A) When the switch 21a, 21b is open in the reverse direction, the train 1-1 is in front of the route of 1RB (that is, the route to landing point B on the main line). It has not been set yet, and no alarm is activated.
[0036]
(B) If the switch 21a, 21b is open in the direction of localization and the path of 1RB is locked (that is, 1RB ), the alarm in the second row of the control table Since the start condition is satisfied, an alarm is started.
[0037]
(iv) The warning of the level crossing A by the train 1-1 on the descending line 1 is stopped when the train 1-1 passes the A level crossing and operates the level crossing control C.
[0038]
(v) As for the train 1-2, it stays on line 21T and the alarm is stopped when the railroad crossing controller F is operated.
[0039]
The flow of the above alarm control processing is shown in FIG. The presence line of the train 1-1 is traced from the information from the electronic interlocking device 5 and the train presence line detection information (steps 101 and 102), the alarm control calculation process is performed based on the control table, and the alarm is started if the alarm start condition is satisfied. Output is instructed (steps 103 and 104).
[0040]
Further, the presence line of the train 1-2 is traced from the information from the electronic interlocking device 5 and the train presence line detection information (steps 101 and 105), the alarm control calculation process is performed based on the control table, and the alarm start condition is satisfied. An alarm output is instructed (steps 106 and 107). The alarm output to the railroad crossing site equipment 3 is output by OR of the alarm outputs of all trains (steps 108 and 109).
[0041]
In this way, by performing alarm control for each train, for example, even when a timer for alarm delay is applied from the starting point controller A to the railroad crossing, for each train and even for each route (whether the train is a route of 1 RA) Since it can have a timer), the alarm time can be optimally controlled.
[0042]
The railroad crossing control device 7 can be incorporated in the electronic interlocking device 5. In other words, only the electronic interlocking device 5 is used as hardware, and a software for executing the above functions is incorporated into the hardware, whereby a crossing control device integrated with the electronic interlocking device 5 can be obtained.
[0043]
If there are multiple railroad crossings in the station, create the railroad crossing control table in Table 1, train tracking section in Fig. 4, train registration table in Table 3, train tracking table and tracking section definition table in Table 5. By doing so, a plurality of level crossings can be controlled. Moreover, even when there are different line sections at one railroad crossing, the same idea can be used.
[0044]
Next, the operation when applied to a single track section will be described. As shown in Table 2, when a train stopped on the down main line departs, the train is on the down main line 4RT according to the instructions in the first row based on the B crossing control table in Table 2. If the route RN to the landing point N is locked ( 4RN ), the alarm is activated no matter where the train is between 1RAT and 32I. And if a train passes the B level crossing in the down direction and the controller C is operated, the level crossing warning is stopped.

Conversely, for the up train, based on the conditions in the second row of Table 2, if the up train is on line 4RT and the controller A is activated, the level crossing control is performed. Stop. However, in this case, the up train stops the level crossing control before passing the B level crossing, but in actual operation, after the operation of the controller C, it is set to stop when a predetermined time elapses. There is no problem.
[0046]
In these crossing controls, the following determination procedure is taken in order to determine the up and down directions of the train. As shown in FIGS. 4 and 5, the section numbers are designated in ascending order from ascending (left: L) to descending (right: R). As a result, when the position is updated in the train tracking table of Tables 5 and 6, it is possible to determine whether the vehicle is going up or down by checking the section number. For example, when an entry is detected in subsection 3- (1) and the presence line is registered, if there is a presence line in section 2, it is determined that the entry has proceeded in the downward direction as an ascending entry from section 2 to section 3 And register down in the direction field.
[0047]
On the other hand, if the train has advanced in subsection 3- (2), and if there is a line in section 2, the train will be considered to have gone up and back in the descending order of section number.
[0048]
In single-track sections, it is necessary to judge the direction of the train when the starting-point controller on the outgoing side detects a standing line, start an alarm if it is on the incoming side, and make an alarm-free judgment if it is on the outgoing side is there.
[0049]
Conventionally, a function for masking the alarm when the departure side starting point detects a train is generally installed by predicting the departure side train in advance by installing a direction detection controller to determine the direction. Adopted. However, in this embodiment, the direction of the train is determined safely and reliably by tracking the train location information.
[0050]
For example, as shown in Table 6, when the controller A detects the presence of a train in FIG. 3, the train 2-1 is in subsection 7- (3) and passes through sections 4 and 6. If it is, you can be sure that it is a descending train and the alarm will not start.
[0051]
In addition, in FIG. 5, when the controller A detects the presence of a train, if there is no train, or there is no train in subsection 7- (3) even if it exists, It is determined that the train is an upstream train without judgment, and a new upstream train identification number 2-1 is issued and registered, and an alarm is started.
[0052]
In this way, in this embodiment, by tracking the position of each train one by one, it is possible to control whether or not to issue a railroad crossing for each train, and when to alarm it should be controlled at which timing, Optimum level crossing alarm control can be performed without useless alarms.
[0053]
【The invention's effect】
The present invention mainly uses trains, and for each train, continuously tracks the start position and the end position of the train as a line, not as points, grasps the traveling direction of the train, and performs warning control of the crossing. This makes it possible to have a timer for each train, and enables accurate, safe, and optimal control of the alarm time.
[0054]
Further, by performing alarm control for each train, unnecessary alarms from the continuing train can be prevented. Furthermore, since the traveling direction can be automatically detected, there is no need to separately install a direction detecting controller.
