To overcome the impreciseness and poor stability of the traditional flux measurement systems, this paper puts forward an SOPC-based flux measurement system that integrates the main control system into an FPGA chip. Centred on the SOPC, the proposed system replaces the traditional analogue integrator with the digital integrator. In addition to digital filtering and auto-calibration, the proposed system realizes automatic range selection, digital integration and other logic functions. It is proved that the system boasts great market potential with measurement accuracy above 0.5% and no drift phenomenon.
