METHOD FOR TRANSFERRING A PRODUCT INFORMATION USING TIME SPREADING SLOT INDEX ASSIGN ALGORISM AT ELECTRONIC SHELF LABEL SYSTEM

摘要

The present invention relates to a method for transferring product information using time spreading slot index assignment algorism at an electronic shelf label system. A tag address which corresponds one to one to a slot number which corresponds to each of slots existing in a PBI which represents the number of slots existing in a CBI the number of CBIs existing in a SPBI the number of SPBIs existing in a PBI, is successively assigned to each of slot indexes with a constant number interval. Thereby, according to bitmap data which includes a payload message of a CBI among the CBIs or CBs in a CBI, product information is transmitted to a corresponding ESL tag. The power consumption of ELS tags is low and transmission efficiency is improved.
