Embodiment 1
[0012] Embodiment 1, the present invention provides a filtering method for seam tracking of magnetron oscillating submerged arc welding, including a passive filter and two multiple feedback Chebyshev active filter joint filters to perform effective filtering sequentially During welding, the clutter collected by the Hall sensor is filtered by the filter, and the obtained waveform A / D is converted into a digital quantity, and the digital quantity transmitted to the microcontroller is accumulated and averaged for multiple judgments; among them, the passive Filter combined with two multiple feedback Chebyshev active filters is composed of an RC passive filter part with two principles Figure 1 The same, but with different parameters of the original multiple feedback Chebyshev active filter, they will complete the high broadband to low narrow frequency filtering. The waveform VIN1 is stabilized by R1, and the high-frequency part is filtered by capacitor C2 to achieve the effect of ...
Embodiment 2
[0014] Embodiment 2, the present invention can also increase the fourth software filtering part, that is, the microcomputer takes 8 data for each operation, calculates the average number after the accumulation, and if it is an ideal state, it will output a section between 0HZ and 4HZ The data. The specific process is as follows: first assign initial values to Y and X, and then perform judgment function calculations, judge △Y and compare it with the set precision (0.004), and output the waveform if it meets the precision requirements, otherwise continue to take 8 to calculate the average value, and judge The size of the average value S and Y, if S is greater than Y, it will be filtered out, if it is less than Y, continue to perform judgment function operations, and then judge the accuracy of △Y, and so on, until the accuracy requirements are met, and the final waveform is output. Due to the first three filtering parts , to improve the filtering efficiency of the fourth part r...
