PURPOSE:To make it possible to measure vibration of a pantograph simply and stably. CONSTITUTION:Acceleration detecting section 1 of an optical fiber acceleration sensor is fixed to the current collecting section, i.e., the shoe 3, of a pantograph. An optical fiber 6 is secured to the pantograph frame 4 by means of a tape 5. The optical fiber 6 is connected, at the other end, with an optical fiber accelerometer body 10 installed in a vehicle. |
