Unpowered ESL terminal receiving distribution history information through UHF RFID communication and distribution history management system using the same

摘要

The present invention relates to a non-powered ESL terminal that transmits distribution history information through UHF RFID communication and a distribution history management system using the same. A non-powered ESL terminal that transmits distribution history information through UHF RFID communication that does not require the installation of infrastructure like the existing ZigBee and does not require a separate power supply as it receives power through external laser signal reception and It relates to a distribution history management system using this. To this end, the present invention includes: an RF receiver for receiving a radio signal of the UHF RFID frequency band including distribution history information from the outside and extracting distribution history information; a memory unit in which the distribution history information extracted from the RF receiver is stored; an image processor for processing the distribution history information stored in the memory unit as distribution history information in the form of a bitmap image; an ESL display unit for displaying distribution history information in the form of a bitmap image processed by the image processor; an ESL driving unit for driving and controlling the distribution history information in the form of a bitmap image processed from the image processor to be displayed on the ESL display unit; and a laser receiver that receives a laser signal from the outside, converts it into power, and supplies the converted power to the memory unit, the image processor, and the ESL driver.
