SELF-POWERED ACCELEROMETER FOR TEST TRAIN

摘要

PURPOSE: A self-powered accelerometer for a test train is provided to prevent the risk of disconnection due to the damage of electric wires which is caused by the expansion of a power line. CONSTITUTION: An energy converting unit(10) converts wind power energy and electric energy. A rectifying unit(20) rectifies alternating current power into direct current power in the energy converting unit through a bridge diode. A condensing unit(30) stores direct current power outputted from the rectifying unit. An accelerometer(40) includes a driving amplifier, and the driving amplifier receives power from the condensing unit and driving the accelerometer.
