Converter valve abnormal discharge monitoring system based on distributed acoustic array group

The invention relates to a converter valve abnormal discharge monitoring system based on a distributed acoustic array group. The monitoring system comprises a plurality of sound array groups which are symmetrically distributed on the two sides of the converter valve tower, the symmetry axis is the common central axis of the converter valve tower, each sound array group comprises a rigid support and a plurality of circular ring sound arrays fixed to the rigid support at equal intervals, and the circular ring sound arrays are arranged in the vertical direction. The distance between adjacent ring sound arrays is equal to the distance between adjacent converter valve bodies in a single converter valve tower, each distributed data acquisition device is fixed on the corresponding rigid support and located at the center of the plurality of ring sound arrays, and the distributed data acquisition devices are in communication connection with the local server; the distributed data acquisition device acquires analog sign
