Straight welded pipe forming control method and straight welded pipe forming equipment

The invention relates to a longitudinal welded pipe forming control method and longitudinal welded pipe forming equipment. The longitudinal welded pipe forming control method comprises the following steps that a first proximity switch sensor is used for detecting a steel plate placed in a plate conveying area, and the width of the steel plate is calculated according to an induction signal of the first proximity switch sensor; the steel plate is conveyed to a plate adjusting area, and the length of the steel plate is calculated through a plurality of laser sensors and a measuring roller encoder which are installed in the plate adjusting area; the position of the steel plate in the plate adjusting area is adjusted according to the calculated width and length of the steel plate, and the steel plate is pushed to a plate forming area; and the large die shank in the plate forming area is controlled to repeatedly roll the steel plate, and the position of the steel plate in the plate forming area is adjusted in the r
