(S200) attracting a switchable permanent magnet mechanism (5) of a B module on the lower surface of a groove-shaped track (2), enabling a sliding block (4) of the B module to be stationary relative to the groove-shaped track (2), enabling a lead screw (41) of the B module to rotate forward, enabling the lead screw (41) of the B module to move forward linearly relative to the sliding block (4), and driving a power mechanism (1), a mechanism connecting frame (10) and wheels (8) to move forward together until the tail end of the lead screw (41) is close to the sliding block (4) and cannot move forward continuously; meanwhile, the magnetic field of the switchable permanent magnet mechanism (5) of the module A is closed and is separated from the groove-shaped track (2), the lead screw (41) of the module A is reversed, the sliding block (4) of the module A linearly moves forwards on the lead screw (41) and drives the switchable permanent magnet mechanism (5) of the module A to linearly move forwards together until the sliding block (4) of the module A approaches the front end of the lead screw (41) and cannot slide continuously;
(S300) repeating the step (S100) and the step (S200) to realize the linear motion of the module unit in the system along the wheel track.
8. A screw rod driving reciprocating magnetic attraction type stepping operation method as claimed in claim 7, characterized in that when stopping or braking, the power mechanism (1) of the module A and the module B stops operating, the screw rods (41) of the module A and the module B stop rotating, and the magnetic field of the switchable permanent magnet mechanism (5) is in an open state and is attracted with the grooved rail (2) to stop the system.
9. An elevator running system, characterized in that the running system employs a screw-driven reciprocating magnetic-attraction type stepping running system according to any one of claims 1 to 6.
