Abstract :
The gas pressure of SF6 circuit breaker working in power system is a critical real-time monitoring parameter. In this paper, bicubic interpolation, Otsu, morphological filtering and Goertzel algorithm are studied on FPGA. In particular, the method HVPL is proposed. Segmentation, extraction and number identification are realized for the SF6 pressure gauge image by applying these strategies, such that intelligent reading for the gauge is achieved. Experiment shows that employing the fast algorithm based on logic circuit to accomplish the machine recognition has advantages of good real-time performance and high recognition rate.
