ESL(ELECTRONIC SHELF LABEL) SYSTEM AND METHOD FOR SCANNING GATEWAY BY ESL(ELECTRONIC SHELF LABEL) TAG USING THE SAME

摘要

ESL labels the present invention relates to a kind of electronic shelf label (ESL) system and for scanning gateway use. A kind of ESL system that the ESL list of labels scanning gateway is supported according to signal strength multiple gateways according to the present invention by scanning multiple gateways, it selects and accesses a gateway with high signal intensity in the upward gateway listed, and by data according to signal strength list user vars feature about in the memory of gateway, and attempt to access that the gateway for without hesitation arriving next high signal intensity according to the listed upward data storage about gateway in memory if there is connecting under the gateway of the high signal intensity of connection delay. According to the present invention, label quickly move through the required sum for searching for gateway channels of reduction to access gateway, thus prevents from unnecessarily consuming battery. ;The 2014 of copyright KIPO submissions;[Reference numerals] (AA) starts; (BB) terminate; (S301) label is connected to the first clock of gateway; (S302) the multichannel ESL systems that scanning is supported; (S303) search complete for all-channel? (S304) upward list of gateways is according to signal strength; (S305) selecting and connect gateway has high signal intensity; (S306) storage is about multiple gateway list user vars feature according to signal strength; Does (S307) gateway disconnect? (S308) gateway and the second high signal intensity are attempted a connection to and is without hesitation based on the related data of list user vars feature multichannel storage gateway
