Description

本発明は、検測車の走行によりデジタルATC(Automatic Train Control)車上装置に必要な路線の曲線、分岐、勾配などの情報を有する保線設備データを取得する装置、さらにそのデータを用いて以前の保線設備データを検査する装置に関するものである。   The present invention is a device for acquiring track maintenance facility data having information such as a curve, a branch, and a slope of a route required for a digital ATC (Automatic Train Control) on-board device by traveling of an inspection vehicle, and further using the data previously It is related with the apparatus which test | inspects track maintenance equipment data.

従来、振り子方式の鉄道車両の車体傾斜制御では、路線のどこに曲線があるのかなどの情報(軌道データ)が不可欠であり、特許文献1には、この車体傾斜制御に用いる軌道データを簡便にかつ信頼性を高く収集する装置が記載されている。   Conventionally, in the vehicle body tilt control of a pendulum type railway vehicle, information (track data) such as where the curve is located is indispensable. Patent Document 1 discloses the track data used for the vehicle body tilt control simply and An apparatus that collects with high reliability is described.

図5に、特許文献1に記載された軌道形状データ収集装置の概略図を示す。
この装置では、車両を支える台車にジャイロスコープが装架されており、曲線のカント量は、走行中に計測した台車枠のロール角速度を積分してロール角信号に変換し、その信号に軌間寸法を掛けることにより算出し、また、曲線の曲率は、走行中に計測した台車枠のヨー角速度とその時の走行速度から算出して、曲線のカント量(外側車線と内側車線の高低差)と曲線の曲率を求めている。

FIG. 5 shows a schematic diagram of the trajectory shape data collection device described in Patent Document 1.
In this device, a gyroscope is mounted on the carriage that supports the vehicle, and the cant amount of the curve integrates the roll angular velocity of the carriage frame measured during travel and converts it into a roll angle signal. The curvature of the curve is calculated from the yaw angular velocity of the bogie frame measured during travel and the travel speed at that time, and the cant amount of the curve (the difference in height between the outer lane and the inner lane) and the curve Seeking curvature.
JP-A-7-65038

デジタルATC車上装置に必要な保線設備データを作成するには、路線の曲線や分岐、勾配などの情報が必要である。しかし、特許文献1に記載された装置では、車体傾斜制御のために必要な情報である曲率とカント量のデータしか得ることができない。また、上記装置では、ジャイロスコープが車両を支える台車に直接装架されていて、台車の振動が激しく、得られた位置や形状信号を波形修正することが必要であって、デジタルATC車上装置に必要な保線設備データを容易に取得することができない。   In order to create track maintenance facility data required for the digital ATC on-board device, information such as curve, branch, and gradient of the route is required. However, the apparatus described in Patent Document 1 can only obtain curvature and cant data, which are information necessary for vehicle body tilt control. In the above apparatus, since the gyroscope is directly mounted on the carriage supporting the vehicle, the carriage vibration is intense, and it is necessary to correct the waveform of the obtained position and shape signal. It is not possible to easily obtain the track maintenance facility data required for the operation.

そこで、本発明では、検測車の走行により保線設備データを得ることのできる装置およびその方法を提案し、さらにそのデータから以前の保線設備データを検査する装置および方法を提案することを目的とする。   Therefore, the present invention proposes an apparatus and method for obtaining track maintenance facility data by running a test vehicle, and further proposes an apparatus and method for inspecting previous track maintenance facility data from the data. To do.

本発明は、検測車の先頭または最後尾等にカメラ等の計測器を備えて走行路線をモニタリングすることにより、曲線情報、分岐情報及び勾配情報を得る装置を提供する。これにより検測車の走行のみで保線設備データを得ることを可能とし、また、得られたデータにより保線設備データの検査を可能とする。   The present invention provides an apparatus for obtaining curve information, branching information, and gradient information by providing a measuring instrument such as a camera at the head or tail of a test vehicle and monitoring a traveling route. As a result, track maintenance facility data can be obtained only by running the inspection vehicle, and track maintenance facility data can be inspected based on the obtained data.

検測車の走行により、曲線情報だけでなく、分岐情報も含めた保線設備データの取得が可能となることで、分岐情報を測量する手間が省ける。さらに、得られたデータと比較することにより、以前の保線設備データが検査可能となることで、データの信頼性を向上させ、不具合の早期発見が可能となる。   By traveling the inspection vehicle, it is possible to acquire track maintenance facility data including not only curve information but also branch information, thereby saving the trouble of surveying branch information. Furthermore, by comparing with the obtained data, the previous track maintenance facility data can be inspected, thereby improving the reliability of the data and enabling early detection of defects.

本発明では、検測車の走行のみで保線設備データを得るという目的を、以下の実施例の方法で実現した。以下、図面を参照して、本発明の実施例を説明する。   In the present invention, the object of obtaining track maintenance facility data only by running the inspection vehicle is realized by the method of the following embodiment. Embodiments of the present invention will be described below with reference to the drawings.

図1は本装置の実施例1の概要を示すものである。本装置は、検測車1の先頭、最後尾、もしくはその両方にカメラ2を備え、また車軸や主電動機軸に取り付けた速度発電機3を備えており、これらの装置からの信号を記録・処理して、保線設備データ4を検出する。   FIG. 1 shows an outline of the first embodiment of the present apparatus. This device is equipped with a camera 2 at the head, tail or both of the inspection vehicle 1 and a speed generator 3 attached to the axle or main motor shaft, and records signals from these devices. The track maintenance facility data 4 is detected by processing.

なお、保線設備データ4とは、線路の曲線、分岐、勾配などの情報を有するデータで、デジタルATC車上装置に必要な情報である。   The track maintenance facility data 4 is data having information such as a curve, a branch, and a slope of the track, and is necessary information for the digital ATC on-board device.

検測車1のカメラ2により通過する(した)路線形状をモニタリングすることで、その画像における左右の軌道の位置関係より曲線、分岐等の情報を検出する。以下にその例を示す(図2参照)。
図2(a)は直線軌道を示す。
図2(b)は、軌道の中心が画面中央より右になった場合を示しており、右への曲線を示す。軌道の中心が画面中央より左になった場合には、左への曲線を示す。
図2(c)は、軌道が分かれた場合を示しており、分岐点を示す。
図2(d)は、軌道間隔が直線軌道の場合よりも広がった場合を示しており、勾配の変化点(下り)を示す。軌道間隔が狭まった場合には、勾配の変化点(上り)を示す。
By monitoring the shape of the route that is passed by the camera 2 of the inspection vehicle 1, information such as curves and branches is detected from the positional relationship between the left and right trajectories in the image. An example is shown below (see FIG. 2).

FIG. 2B shows a case where the center of the trajectory is on the right side of the screen center, and shows a curve to the right. If the center of the trajectory is to the left of the center of the screen, a curve to the left is shown.
FIG. 2 (c) shows a case where the trajectory is divided and shows a branch point.
FIG. 2D shows a case where the trajectory interval is wider than that in the case of a straight trajectory, and shows the change point (down) of the gradient. When the orbit interval is narrowed, the slope change point (up) is indicated.

これらの状態において、事前に求めた校正値を適応することにより、曲率半径を求める。なお、これらの曲線や分岐が、線区の基準点からどれくらいの距離で開始し、どれくらい続くのかについても同時に記録する。各瞬間における基準点からの移動距離や走行速度は、車軸や主電動機軸に取り付けた速度発電機3の出力と車輪の直径から算出する。
さらに、線路に沿って設置されている自動列車停止装置の地上子6などから得る地点検地信号などにより補正を行ってデータの精度を高め、曲率半径や分岐点のデータに合わせる。
In these states, the curvature radius is obtained by applying the calibration value obtained in advance. It is also recorded at the same time how far and how long these curves and branches start from the line segment reference point. The movement distance and traveling speed from the reference point at each moment are calculated from the output of the speed generator 3 attached to the axle and the main motor shaft and the diameter of the wheel.
Furthermore, the accuracy of the data is increased by correction based on the ground inspection signal obtained from the ground element 6 of the automatic train stopping device installed along the track, and the data is adjusted to the data of the curvature radius and the branch point.

以上のようにして得られたデータは、まず曲率半径のデータや分岐点のデータにそれぞれ分離し平均化処理を行う。これらのデータを以前からある保線設備データの各々のデータと重ね合せにより比較する。そして、検査手段5で、測定したデータと以前からの保線設備データとの間に差が大きい個所のみを摘出する。   The data obtained as described above is first separated into curvature radius data and branch point data, and averaged. These data are compared with each of the existing track maintenance facility data by superposition. Then, the inspection means 5 extracts only the portions where there is a large difference between the measured data and the previous track maintenance facility data.
