Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a simply structured and inexpensive detecting device for obstacles on railway tracks that can reliably identify only obstacles beyond the clearance limit of architecture.SOLUTION: A rotary encoder 4 that obtains, in a mode interlocked with wheel shafts, positional data based on the distance from a reference position is disposed on a bogie 2 equipped with wheels 2a that can roll on train rails R and R. A 3D scanner 3 that scans its surroundings with a laser beam L1 and measures the distances and angles of objects O1 and O2 irradiated with the laser beam L1 is mounted on a bogie 2. A controller 5 mounted on the bogie 2 detects the positions of the objects O1 and O2 on the basis of positional data obtained by the rotary encoder 4 and data measured by the 3D scanner 3 and, after excluding measured data corresponding to aerial electric train lines and metal fittings, identifies the obstacle O2 impeding train operation, and the controller 5 calculates the invaded extent by making accurate measurement with laser range finder 6 mounted on the bogie 2.SELECTED DRAWING: Figure 1
【課題】 建築限界を逸脱した支障物のみを確実に特定でき、かつ簡易な構成で安価な鉄道線路の支障物検出装置を提供する。【解決手段】 鉄道線路のレールR,R上を転動可能な車輪2aを備えた台車2に、車軸に連動して基準位置からの距離に基づく位置データを得るロータリーエンコーダ4を設ける。周辺をレーザ光L1でスキャンしレーザ光L1が照射された対象物O1,O2の距離及び角度を測定する測域センサ3を台車2上に搭載する。台車2上に搭載した制御装置5はロータリーエンコーダ4による位置データ及び測域センサ3による測定データに基づいて、対象物O1,O2の位置を検出し、架空電車線・金具類に相当する測定データを除外した上で、列車運行上の支障物O2を特定し、台車2上に搭載したレーザ距離計6で精度高く距離を測定することにより制御装置5が侵入量を算出する。【選択図】 図1 |
