Abstract:
     The invention relates to beam type optical fiber grating dynamic weighing system. It is made up of beam type optical fiber grating dynamic weighing structure and dynamic data detection structure. The former includes frame type base, bearing face plate, and strain beam. The latter includes light source, the first and second photovoltaic conversion module, data acquisition module, data processing module, and the first, second, and third splitters. The purpose of the invention is to offer a dynamic weighting structure which has simple structure, high interference killing feature, and good long-term stability.
