MEASURING SYSTEM OF CATENARY CONTACT AND IMPECT FORCE

A system for measuring impact acceleration and a contact force is provided to continuously maintain an optimum current collection state of a pantograph and a catenary by analyzing a mechanical impact of the catenary and the pantograph. A sensor measuring device(100) includes a sensor part, a sensor measuring part, a first light transmitting/receiving part, a battery, and an A/D converter. The sensor part measures acceleration information and a contact force between a pantograph(1) and a catenary(2). The sensor measuring part converts the acceleration information and the contact force into a metering data. The first light transmitting/receiving part converts the metering data of the sensor measuring part into an optical signal. The battery supplies a power. The A/D converter converts the power of the battery into a fixed voltage. A data analyzing device(200) receives the measuring data from the sensor measuring device, and analyzes the impact acceleration and the contact force between the pantograph and the catenary.
