Description

本発明は、車両の屋根上に測域センサを設置し、架線高さを測定する架線測定装置及び方法に関する。   The present invention relates to an overhead line measuring apparatus and method for installing a range sensor on a vehicle roof and measuring the overhead line height.

電車に電気を供給するために設けられている架線は、その高さが所定範囲内に収まるように決められている。よって、架線高さの測定は重要である。この架線高さの測定方法のひとつに、車両の屋根上に設置した測域センサを用いる方法が挙げられるが、当該方法を用いた場合、測定誤差が生じることがある。   The overhead wire provided for supplying electricity to the train is determined so that its height falls within a predetermined range. Therefore, the measurement of overhead line height is important. One method of measuring the overhead line height is to use a range sensor installed on the roof of the vehicle. However, when this method is used, a measurement error may occur.

よって、特許文献１には、ノイズによる測域センサの測定誤差を低減する技術が開示されている。   Therefore, Patent Document 1 discloses a technique for reducing the measurement error of the range sensor due to noise.

特開２０１０‐２４３４１６号公報JP 2010-243416 A

しかしながら、特許文献１に開示される技術では、電車がトンネル内に進入したときの測定誤差を低減することはできない。   However, the technique disclosed in Patent Document 1 cannot reduce measurement errors when a train enters a tunnel.

すなわち、測域センサ、架線及びトンネル天井が、所定の位置関係になると、測域センサによる架線高さの測定値が真値よりも上方にずれる現象が起こる。   That is, when the range sensor, the overhead line, and the tunnel ceiling have a predetermined positional relationship, a phenomenon occurs in which the measured value of the overhead line height by the range sensor is shifted upward from the true value.

上記現象の要因のひとつとして、測域センサのレーザ光の直径が距離に比例して大きくなることが挙げられる。これについて、図７，８を用いて説明する。   One of the causes of the above phenomenon is that the diameter of the laser beam of the range sensor increases in proportion to the distance. This will be described with reference to FIGS.

図７は、測域センサのレーザ光が照射された架線の側面図（上図）、及び、測域センサと架線との位置関係を示した図（下図）からなる、測域センサのレーザ光漏れの発生を説明する概略図である。図７（ａ）は、測域センサと架線との距離が近い（下図における破線両矢印が短い）場合を、図７（ｂ）は、測域センサと架線との距離が離れている（下図における破線両矢印が長い）場合を、それぞれ示しており、図７（ａ）（ｂ）共に、上図における一点鎖線楕円は、測域センサのレーザ光の照射範囲を示している。   FIG. 7 is a side view of the overhead line irradiated with the laser beam of the range sensor (upper figure) and a diagram showing the positional relationship between the range sensor and the overhead line (lower figure). It is the schematic explaining generation | occurrence | production of a leak. FIG. 7A shows the case where the distance between the range sensor and the overhead line is short (the broken-line double arrow in the lower figure is short), and FIG. 7B shows the distance between the range sensor and the overhead line (lower figure). In FIG. 7 (a) and FIG. 7 (b), the alternate long and short dash line ellipse indicates the laser beam irradiation range of the range sensor.

図７（ａ）に示すように、測域センサ１１と架線２１との距離が近い場合、測域センサ１１のレーザ光の照射範囲は、架線２１の側面にほぼ収まり、レーザ光漏れは無い。   As shown in FIG. 7A, when the distance between the range sensor 11 and the overhead line 21 is short, the laser beam irradiation range of the range sensor 11 is almost within the side surface of the overhead line 21, and there is no laser light leakage.

しかし、図７（ｂ）に示すように、測域センサ１１と架線２１との距離が離れている場合、レーザ光の直径は大きくなり、測域センサ１１のレーザ光の照射範囲は、架線２１の側面に収まらず、レーザ光漏れが発生する。   However, as shown in FIG. 7B, when the distance between the range sensor 11 and the overhead line 21 is large, the diameter of the laser beam becomes large, and the irradiation range of the laser beam of the range sensor 11 is the overhead line 21. Laser light leaks.

図８は、屋外とトンネル内とのレーザ光漏れの違いを説明する概略図である。図８（ａ）は、屋外の場合を、図８（ｂ）は、トンネル内の場合を、それぞれ示しており、図８（ａ）（ｂ）共に、図中の一点鎖線矢印は、測域センサのレーザ光の軌道を示している。   FIG. 8 is a schematic diagram illustrating the difference in laser light leakage between outdoors and inside a tunnel. 8 (a) shows the case of outdoor, and FIG. 8 (b) shows the case of inside a tunnel, respectively. In both FIGS. The trajectory of the laser beam of the sensor is shown.

上述のように、測域センサ１１のレーザ光漏れが発生している場合であっても、図８（ａ）に示すように、車両２３が屋外であれば、漏れたレーザ光はそのまま拡散していくだけであるため、架線高さの測定値に影響はない。   As described above, even when the laser beam leaks from the range sensor 11, if the vehicle 23 is outdoors as shown in FIG. 8A, the leaked laser beam is diffused as it is. The measured value of overhead wire height is not affected.

ところが、図８（ｂ）に示すように、車両２３がトンネル内であると、漏れたレーザ光が架線２１上方のトンネル２２の天井にて反射することにより、架線高さの測定値が上方にずれ、測定誤差が発生することになる。   However, as shown in FIG. 8B, when the vehicle 23 is in the tunnel, the leaked laser light is reflected by the ceiling of the tunnel 22 above the overhead line 21, so that the measured value of the overhead line height increases. Deviation and measurement error will occur.

そこで、本発明は、測域センサによるトンネル内における架線高さの測定誤差を補正する架線測定装置及び方法を提供することを目的とする。   Therefore, an object of the present invention is to provide an overhead line measuring apparatus and method for correcting an overhead line height measurement error in a tunnel by a range sensor.

［実施例１］
本発明の実施例１に係る架線測定装置について、まず、図１，２を用いて説明する。図１は、本装置の設置例を示す概略図である。また、図２は、本装置のブロック図である。なお、図２中では、簡略化のため、電車がトンネル内の場合の処理のみを表し、屋外の場合を省略している。 [Example 1]
First, an overhead wire measuring apparatus according to Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a schematic diagram illustrating an installation example of the present apparatus. FIG. 2 is a block diagram of this apparatus. In FIG. 2, for simplification, only the processing when the train is inside the tunnel is shown, and the case where it is outdoors is omitted.

図１に示すように、本装置は、車両２３の屋根上に設置され、架線２１の高さ（以下「架線高さ」と記載）とトンネル２２の天井の高さ（以下「天井高さ」と記載）とを測定する測域センサ１１、及び、測域センサ１１による測定値を補正する演算装置１２を備えるものである。   As shown in FIG. 1, the present apparatus is installed on the roof of a vehicle 23, and the height of the overhead line 21 (hereinafter referred to as “overhead line height”) and the height of the ceiling of the tunnel 22 (hereinafter referred to as “ceiling height”). And a calculation device 12 that corrects a measurement value obtained by the range sensor 11.

上記演算装置１２は、図２に示すように、処理メモリ１３、補正処理部１４及びデータ出力部１５を備える。   The arithmetic unit 12 includes a processing memory 13, a correction processing unit 14, and a data output unit 15, as shown in FIG.

上記処理メモリ１３は、電車がトンネル２２内にある場合、測域センサ１１から入力した架線高さの測定値と天井高さの測定値とを保存し、補正処理部１４に出力する。また、補正処理部１４から入力した、補正後の架線高さの測定値を保存し、データ出力部１５に出力する。一方、電車がトンネル２２内にない場合、すなわち、屋外の場合には、測域センサ１１から入力した架線高さの測定値を保存し、当該測定値を、そのままデータ処理部１５に出力する。   When the train is in the tunnel 22, the processing memory 13 stores the overhead line height measurement value and the ceiling height measurement value input from the range sensor 11 and outputs them to the correction processing unit 14. In addition, the corrected measurement value of the overhead line input from the correction processing unit 14 is stored and output to the data output unit 15. On the other hand, when the train is not in the tunnel 22, that is, when it is outdoors, the measured value of the overhead line height input from the range sensor 11 is stored and the measured value is output to the data processing unit 15 as it is.

上記補正処理部１４は、予め補正テーブル１４ａが設けられており、当該補正テーブル１４ａに基づき、処理メモリ１３から入力した架線高さの測定値と天井高さの測定値とから、架線高さの測定値を真値と一致させる補正を行い、補正後の架線高さの測定値を、処理メモリ１３に出力する。   The correction processing unit 14 is provided with a correction table 14a in advance, and based on the correction table 14a, the overhead line height measurement value and the ceiling height measurement value input from the processing memory 13 are calculated. Correction is performed to match the measured value with the true value, and the corrected measured value of the overhead line height is output to the processing memory 13.

上記データ出力部１５は、処理メモリ１３から入力した、架線高さの測定値、又は、補正処理部１４による補正後の架線高さの測定値を、外部に出力する。   The data output unit 15 outputs the measurement value of the overhead line height input from the processing memory 13 or the measurement value of the overhead line height corrected by the correction processing unit 14 to the outside.

ここで、上記補正テーブル１４ａについて、図３〜６を用いて説明する。図３は、補正テーブルの作成手順を示す概略図である。また、図４は、補正テーブルの例を示す概略図である。さらに、図５は、補正テーブルを用いて架線高さの真値を求める手順を説明する概略図である。そして、図６は、本装置の作動を説明するフローチャートである。   Here, the correction table 14a will be described with reference to FIGS. FIG. 3 is a schematic diagram showing a procedure for creating a correction table. FIG. 4 is a schematic diagram illustrating an example of a correction table. Furthermore, FIG. 5 is a schematic diagram illustrating a procedure for obtaining a true value of the overhead line height using the correction table. FIG. 6 is a flowchart for explaining the operation of the present apparatus.

まず、補正テーブル１４ａの作成手順について説明する。図３に示すように、架線２１及びトンネル２２の天井と（補正テーブル１４ａの作成に必要な測域センサ１１の測定範囲において）同様の形状及び材質からなる試験用架線３１及び試験用壁面３２を、測域センサ１１の上方に設置する。   First, a procedure for creating the correction table 14a will be described. As shown in FIG. 3, the overhead wire 21 and the ceiling of the tunnel 22 and the test overhead wire 31 and the test wall surface 32 made of the same shape and material (in the measurement range of the range sensor 11 necessary for creating the correction table 14a) are provided. It is installed above the range sensor 11.

図３中の破線円及び破線矩形は、試験用架線３１及び試験用壁面３２の高さを、次々と変更していく様子を示している。このようにして、試験用架線３１及び試験用壁面３２の様々な高さの組み合わせにつき、測域センサ１１で測定し、測定値を記録していく。また、破線両矢印で示すように、上記組み合わせにつきそれぞれ真値も採っておく。ただし、試験用壁面３２については、測域センサ１１による測定値さえ分かればよく、真値を採ることは必須の要件ではない。   A broken line circle and a broken line rectangle in FIG. 3 indicate how the heights of the test overhead line 31 and the test wall surface 32 are changed one after another. In this way, various height combinations of the test overhead wire 31 and the test wall surface 32 are measured by the range sensor 11 and the measured values are recorded. Further, as indicated by the broken-line double arrows, true values are also taken for the combinations. However, for the test wall surface 32, it is only necessary to know the measured value by the range sensor 11, and taking a true value is not an essential requirement.

上述の作業により、試験用架線３１の高さの測定値、試験用壁面３２の高さの測定値、及び、試験用架線３１の高さの真値の相関関係がわかる。当該相関関係はそのまま、架線高さの測定値、天井高さの測定値、及び、架線高さの真値の相関関係となる。よって、架線高さの測定値、天井高さの測定値、及び、架線高さの真値の相関関係に基づいた表を作成することができ、これを補正テーブル１４ａとする。   Through the above-described operation, the correlation between the measured value of the height of the test overhead line 31, the measured value of the height of the test wall surface 32, and the true value of the height of the test overhead line 31 is known. The correlation is directly the correlation of the measured value of the overhead line height, the measured value of the ceiling height, and the true value of the overhead line height. Therefore, a table based on the correlation between the measured value of the overhead line height, the measured value of the ceiling height, and the true value of the overhead line height can be created, and this is used as the correction table 14a.

補正テーブル１４ａは、例えば、図４に示すように、縦軸を天井高さの測定値、横軸を架線高さの真値とし、表中の各欄に架線高さの測定値を記入したものとすればよい。なお、図４では、架線高さの測定値が１行しか記載されておらず、他は空欄となっているが、実際には全ての欄が埋まっている。   In the correction table 14a, for example, as shown in FIG. 4, the vertical axis is the measured value of the ceiling height, the horizontal axis is the true value of the overhead line height, and the measured value of the overhead line height is entered in each column in the table. It should be. In FIG. 4, only one line of the measured value of the overhead line height is described, and the others are blank, but actually all the columns are filled.

上述のようにして予め設けられた補正テーブル１４ａを用いて、補正処理部１４において、架線高さの測定値と天井高さの測定値とから、架線高さの真値を求める手順を、以下、図５を用いて説明する。   The procedure for obtaining the true value of the overhead line height from the measured value of the overhead line height and the measured value of the ceiling height in the correction processing unit 14 using the correction table 14a provided in advance as described above is as follows. This will be described with reference to FIG.

まず、補正テーブル１４ａにおいて、測域センサ１１によりトンネル２２の天井を測定することで得られた天井高さの測定値に該当する行を見つけ、当該行の中から、測域センサ１１により架線２１を測定することで得られた架線高さの測定値に該当する値を見つける。そして、当該値に対応する横軸の値が架線高さの真値となる。図５に示す例では、天井高さの測定値が３０１で、架線高さの測定値が１０６のとき、架線高さの真値、すなわち、補正後の架線高さの測定値は１０３となる。   First, in the correction table 14a, a line corresponding to the measurement value of the ceiling height obtained by measuring the ceiling of the tunnel 22 by the range sensor 11 is found, and the overhead line 21 is detected by the range sensor 11 from the line. Find the value corresponding to the measured overhead line height obtained by measuring. And the value of the horizontal axis corresponding to the said value becomes a true value of overhead line height. In the example shown in FIG. 5, when the measured value of the ceiling height is 301 and the measured value of the overhead line height is 106, the true value of the overhead line height, that is, the measured value of the corrected overhead line height is 103. .

以下、本装置の作動について、図６を用いて説明する。   Hereinafter, the operation of the present apparatus will be described with reference to FIG.

まず、ステップＳ１では、撮影環境がトンネル２２内か否か判断する。これは、電車の走行距離が、予め設定したトンネル区間であるか否かで判断する機能を、演算装置１２に備えるものとすればよい。トンネル２２内でない場合、すなわち、屋外の場合には、ステップＳ２に移行し、トンネル２２内の場合には、ステップＳ３に移行する。   First, in step S1, it is determined whether or not the shooting environment is in the tunnel 22. In this case, the arithmetic device 12 may be provided with a function of determining whether the travel distance of the train is a preset tunnel section. If it is not in the tunnel 22, that is, if it is outdoors, the process proceeds to step S2, and if it is in the tunnel 22, the process proceeds to step S3.

ステップＳ２では、測域センサ１１で、架線高さを測定する。図８（ａ）のように、屋外では、漏れたレーザ光を反射する壁面がないため、壁面影響に関する補正を行う必要はない。したがって、この架線高さの測定値は、処理メモリ１３、データ出力部１５を介して、そのまま外部に出力される。   In step S <b> 2, the range sensor 11 measures the overhead line height. As shown in FIG. 8A, since there is no wall surface that reflects the leaked laser beam outdoors, there is no need to perform correction regarding the wall surface effect. Therefore, the measured value of the overhead wire height is directly output to the outside via the processing memory 13 and the data output unit 15.

ステップＳ３では、測域センサ１１で、架線高さ及び天井高さを測定する。この架線高さの測定値と天井高さの測定値とは、処理メモリ１３を介して、補正処理部１４に出力される。   In step S3, the range sensor 11 measures the overhead line height and the ceiling height. The measured value of the overhead line height and the measured value of the ceiling height are output to the correction processing unit 14 via the processing memory 13.

ステップＳ４では、補正処理部１４により、架線高さの測定値を補正し、補正後の架線高さの測定値を、処理メモリ１３、データ出力部１５を介して、外部に出力する。   In step S4, the correction value of the overhead line height is corrected by the correction processing unit 14, and the corrected measurement value of the overhead line height is output to the outside via the processing memory 13 and the data output unit 15.

以上、本発明の実施例１に係る架線測定装置について説明したが、換言すれば、本装置は、車両２３の屋根上に設置され、架線高さとトンネル天井高さとを測定する測域センサ１１、及び、測域センサ１１による測定値を補正する演算装置１２を備える架線測定装置であって、演算装置１２は、車両２３がトンネル２２内にある場合に、予め設けられた架線高さの測定値、トンネル天井高さの測定値、及び、架線高さの真値の相関関係に基づき、架線高さの測定値を、架線高さの真値と一致させる補正を行うものである。   The overhead line measuring apparatus according to the first embodiment of the present invention has been described above. In other words, the apparatus is installed on the roof of the vehicle 23, and the range sensor 11 that measures the overhead line height and the tunnel ceiling height, And the overhead line measuring apparatus provided with the calculating device 12 which correct | amends the measured value by the range sensor 11, Comprising: When the vehicle 23 exists in the tunnel 22, the calculating device 12 is a measured value of the overhead line provided beforehand. Based on the correlation between the measured value of the tunnel ceiling height and the true value of the overhead line height, correction is performed so that the measured value of the overhead line height matches the true value of the overhead line height.

また、本発明の実施例１に係る架線測定方法としては、測域センサ１１による測定値を補正する架線測定方法であって、架線高さの測定値、トンネル天井高さの測定値、及び、架線高さの真値の相関関係を、予め求めておき、トンネル２２内での測域センサ１１の測定においては、架線高さの測定値を、架線高さの真値と一致させる補正を行うものである。   Further, the overhead wire measurement method according to the first embodiment of the present invention is an overhead wire measurement method for correcting the measurement value by the range sensor 11, wherein the overhead wire height measurement value, the tunnel ceiling height measurement value, and The correlation between the true values of the overhead line heights is obtained in advance, and in the measurement of the range sensor 11 in the tunnel 22, correction is performed so that the measured values of the overhead line heights coincide with the true values of the overhead wire heights.
