The system enlcomprises two wheel carriers, which are symmetrically arranged on two sides of an I-beam track (1). A positioning wheel (4) and CA several traveling wheels (2) are provided on the wheel carriers, the traveling wheels (2) traveling on an upper end surface of a bottom plate of the I-beam track (1), and the positioning wheel (4) being in meshing transmission with a toothed rack (19) at a lower end of the bottom plate of the I-beam track (1). A mounting frame (18) and a connection base (9), which is used for connecting a monorail crane, W O 2023/20 1993 A 1 |||||||||1|||||||||||||||||||||||||||||HI||I|I||||||DI |||||||||||||||||||||| R H$ i1I, Jiangsu 221000 (CN) tiiL(DU, Mai); JI &-l r A.

A rotation angle sensor (7) is provided on the positioning wheel (4), and the rotation angle sensor (7) is electrically connected to the single-chip microcomputer (12). Crane heads at two ends of the monorail crane are each provided with a coordinate updating unit (24). The high-precision positioning of the monorail crane is implemented by means of achieving the high-precision meshing between the positioning wheel (4) and the toothed rack (19) on the I-beam track (1) and then calculating the displacement of the positioning wheel (4).
