Static electricity optical fiber measurement appliance and measurement method

Abstract

The invention provides a static electricity optical fiber measurement appliance and a measurement method. The static electricity optical fiber measurement appliance comprises a light emitting device, a coating film static electricity test device, a light receiving device, a photovoltaic conversion unit and a single chip microcomputer. The coating film static electricity test device is connected with a tested object through static electricity conducting wires to collect static electricity amount of the tested object. The coating film static electricity device opens at an angle theta after receiving the static electricity amount. Light sent out through the light emitting device is lit on the coating film static electricity device, is received by the light receiving device after being reflected and is converted into an electric signal and sent to the single chip microcomputer through the photovoltaic conversion unit. According to the static electricity optical fiber measurement appliance and the measurement method, the opening degree caused by that the coating film static electricity test device receives static electricity is ingeniously combined with a light reflection principle, and therefore the static electricity amount of the tested object is calculated. Due to the fact that loss in the two process of opening the coating film static electricity test device at a certain degree after the coating film static electricity test device receives static electricity and light reflection is very small, the electricity amount in the inner portion of an oil tank is accurately obtained, and the operation is simple.
