The defect pixel block refers to a facula pixel block corresponding to the defect line to be detected. The pixel site correspondence rule refers to a rule that the secondary light spot blocks in the secondary light spot block set and the detection pixel blocks in the detection pixel block set have pixel positions in one-to-one correspondence. When the secondary light spot block set and the inspection pixel block set do not meet the pixel site corresponding rule, it indicates that the secondary light spot block set cannot correspond to the inspection pixel block set due to the possible position regulation error (for example, error in the process of regulating the central azimuth angle of the optimal laser beam).

Further, the diamond line position correspondence rule means that only spot blocks or no spot blocks can be simultaneously generated on the same diamond line position, when only one diamond line is broken, no spot block is simultaneously generated on the corresponding diamond line position, and when the diamond line is broken continuously in the process of moving the optimal laser beam central position angle, the situation that the diamond line position correspondence rule is not met occurs.

In detail, when the primary light spot block set and the secondary light spot block set meet the diamond wire position corresponding rule, the diamond wire breakage only occurs at the position of the defect wire to be detected, and therefore, only single-wire breakage alarm is needed for the diamond wire position to be detected.
