Come over the bulk metal signal detected, judges the signal time difference between two metal detecting devices and belt speed product, if
The threshold range for meeting transmission belt distance between the two, if if meeting this condition, then it is assumed that this bulk metal signal is
Real bulk metal, follow-up corresponding progress lock out operation；If being unsatisfactory for this condition, then it is assumed that be error detection, not to this
Bulk metal signal carries out lock out operation.
Preferably, in practical application, the processor 300 according to the first time of the first signal and second signal it is poor and
The belt speed of upper conveyor belt, judges whether the first time poor product with belt speed is equal to first distance.If equal,
Prove there is bulk metal on conveyer belt, if unequal, then it is assumed that do not have.
