Embodiment Construction
[0008] The system structure of the present invention is described in detail in conjunction with the working process.
[0009] For the specific structure of the high-speed power harmonic detector, see figure 1 , The model of the ARM main controller is selected as the single-chip microcomputer of the C8205F120 model.
[0010] The technical scheme of the present invention is realized as follows: signal conditioning module, A / D sampling control module, FPGA coprocessor module, ARM main controller module (C8205F120), and display module. Among them, when the high-speed power harmonic detector is working, the function of the signal conditioning module is to convert the strong electric signal into a weak electric signal, and calibrate the weak electric signal to be sampled, so that the sampling voltage and current signal meet the requirements of the amplitude-frequency characteristics; The function of the signal sampling conversion module is to sample and convert the signal to be det...
