Rotor identity recognition method and device and linear transmission system

The invention relates to the technical field of transmission systems, in particular to a rotor identity recognition method and device and a linear transmission system. The rotor identity recognition method is applied to the linear transmission system, each rotor of the linear transmission system is provided with a first code channel, the first code channel is a magnetic channel with a plurality of N poles and a plurality of S poles arranged according to a preset sequence in the transmission direction, and a stator is provided with a first sensing element corresponding to the first code channel; the first sensing element can interact with a first code channel on the opposite rotor to read a real-time sequence value corresponding to the opposite rotor; the method comprises the following steps: acquiring a real-time sequence value read by a first sensing element; comparing the real-time sequence value with a reference sequence in pre-stored identity reference information; and determining the identity of the move
