Abstract:
    This invention relates to rotation mechanic shot large dynamic range without blind area variable frequency control method according to shot work frequency to make the shot work in large range, which comprises the following steps: firstly computing mechanic shot to work normally in work frequency range according to disc mechanic shot space occupancy and different work distance; then computing normal work frequency middle value as certain detection distance for best work frequency; finally according to real conditions to limit and need several mechanic shot control pattern to select one.
