To provide a pantograph measuring system which can measure a contact state such as a contact force between a trolley line and a slide plate of a pantograph by a simple constitution.SOLUTION: A pantograph measuring system 101 comprises a sound detection part 3 for detecting a sound generated by the contact of a trolley line 2 and a slide plate 12 of a pantograph in the pantograph 51, and an estimation part 60 having a contact force estimation part 61 for estimating a contact state such as a contact force between the trolley line and the slide plate on the basis of a level of the sound detected by the sound detection part. The sound detection part has a plurality of microphones 31 to 42 located at a side opposite to a side at which the trolley line is located with respect to the slide plate, and aligned along longitudinal directions of the plurality of slide plate parts 121 to 132.SELECTED DRAWING: Figure 1
【課題】トロリ線とパンタグラフの摺り板との接触力等の接触状態を簡単な構成で測定できる、パンタグラフ用測定システムを提供する。【解決手段】パンタグラフ用測定システム101は、パンタグラフ51において、トロリ線2とパンタグラフの摺り板12との接触により生ずる音を検出する音検出部3と、音検出部により検出された音のレベルに基づいて、トロリ線と摺り板との接触力等の接触状態を推定する接触力推定部61を有する推定部60と、を備える。音検出部は、摺り板に対しトロリ線が位置する側とは反対側に位置し、摺り板部121〜132の長手方向に沿って配列された複数のマイクロフォン31〜42を有する。【選択図】図1
