The invention discloses an intelligent pace production line system realizing single-line and double-line switching. The system comprises an equipment front part power main frame, a distribution box, an equipment middle part connecting frame, an equipment rear part frame, a front displayer and a rear displayer; the equipment front part power main frame, together with the equipment middle part connecting frame and the equipment rear part frame, forms whole equipment; an equipment levelness adjusting foot margin is installed at the bottom of the equipment; a supporting leg levelness adjusting nutis installed on the equipment levelness adjusting foot margin; the distribution box is installed on the equipment front part power main frame through a bolt; and the front displayer and the rear displayer are installed on the equipment front part power main frame through connecting rods. The system disclosed by the invention can realize single-line/double-line switching; when products of two styles are to be produced, two single lines run, production workers are divided into two groups for operation and processing; one wide line runs when the two lines run synchronously so as to complete moreworking procedures and manufacture a style requiring complicated technology, and moreover product quantity can be recorded intelligently, and the work efficiency can be reflected.
