Method and device for checking asynchronous multi-reader-writer radio frequency tags with different tag distributions

The invention discloses an asynchronous multi-reader-writer radio frequency tag checking method and device with different tag distributions, and relates to the technical field of tag checking, and the method comprises the steps: sensing the tag distribution in the coverage range of each reader-writer, and obtaining the tag distribution condition; performing master-slave reader-writer division on the reader-writer to obtain all master-slave reader-writer division schemes; based on the calculated theoretical total time consumption, obtaining an optimal division scheme for performing master-slave division on the reader-writer; according to the obtained optimal division scheme, the master reader-writer calculates and executes an optimal checking method based on the local loss rate to complete checking, and the slave reader-writer calculates and executes an optimal checking method with the local loss rate being 0 to complete checking; and updating the to-be-identified tag set, and when the to-be-identified tag set
