Warehousing logistics door system based on UHF RFID technology

Abstract

The invention relates to a warehousing logistics system based on UHF RFID technology. The warehousing logistics system comprises RFID tags, an RFID reader-writer, RFID antennas, a single-chip microcomputer, a photoelectric switch, a background server and a display screen, wherein the RFID tags are embedded on the surfaces of cargo boxes, the RFID antenna is connected with the RFID reader-writer, and the RFID antennas are symmetrically arranged on vertical door frames on both sides of a logistics gate, the RFID reader-writer is connected to the single-chip microcomputer through a serial port, the single-chip microcomputer is connected with the photoelectric switch through a GPIO interface, the photoelectric switch is arranged under the RFID antennas, the single-chip microcomputer is connected to the background server through the network, the background server is connected with the display screen, and the display screen is arranged on the wall at one side of the logistics gate. The warehousing logistics system can carry out the batch scanning of RFID tags and complete the scanning at the same time as goods entering and leaving a warehouse. When the goods normally pass through the logistics gate, the information of all the goods can be collected in real time without waiting.

Description

technical field [0001] The invention relates to automatic storage and storage technology, in particular to a storage logistics door system based on ultra-high frequency RFID technology. Background technique [0002] Most of the current warehousing in and out of the warehouse adopts the method of manual inventory or QR code scanning. Although manual inventory is more flexible and does not require additional additional equipment, it is time-consuming and labor-intensive. When the number of goods is large, the inventory is inefficient and error-prone. Although the method of using the QR code has a high accuracy rate and can be connected to the background system to upload inventory data, it requires staff to take inventory one by one in a single room, and the efficiency improvement is not obvious. UHF RFID technology (860MHz~960MHz) can be used to take advantage of RFID batch scanning and fast scanning to complete scanning while leaving the warehouse, and directly upload the in...
