Problems solved by technology

However, most of the existing systems rely on high-power UHF technology for coupling between RF tags and RFID readers, so there is a problem of high cost; and, in the existing UHF technology, In order to ensure that the RFID reader can be smoothly coupled with the RF tag, the forward link transmission power of the RFID reader is required to be much greater than the reflected power of the reverse link of a single RF tag, so that the distance between the adjacent RF tags When it is relatively close, the same RFID reader will detect multiple radio frequency tags, and then there will be a problem of recognition error

Embodiment 1

[0044] This embodiment provides an RFID-based dangerous goods management system, please refer to figure 2 As shown, it is a schematic structural diagram of the management system, including an isolation storage cabinet 10, a dangerous goods label 20, a reading and writing device 30, a PC upper computer 40, a LAN switch 50, a cloud platform 60 and a mobile terminal 70;

[0045] in:

[0046] The isolated storage cabinet 10 is a metal cabinet, and there are multiple independent storage chambers 11 inside the cabinet body. Each independent storage chamber 11 stores a dangerous article independently, and the independent storage chambers 11 are equipped with airtight doors 12 to realize the safety of dangerous goods. Closed storage of goods; on the airtight door 12, a combination lock 13 is installed to realize encrypted storage of dangerous goods.

[0047] The dangerous goods label 20 adopts a low-power, ultra-high frequency RFID radio frequency label, which is packaged or pasted ...

Embodiment 2

[0058] This embodiment provides an RFID-based dangerous goods management method, please refer to Figure 7 As shown, it is a flow chart of the management method, including:

[0059] S1. Based on the reader-writer 33, a plurality of coupling antennas 34 are sequentially addressed and accessed, and the coupling antenna 34 is coupled with the dangerous goods label 20 to obtain address data; in the process of obtaining the address data, the coupling antenna 34 and the dangerous goods label The coupling can be completed under the condition of low power between 20. The principle is: in the closed metal isolation storage cabinet, the radio frequency signal sent by the coupling antenna will be reflected, so that the radio frequency signal will be enhanced, thus ensuring the smooth operation of the coupling antenna. Coupling with dangerous goods labels to achieve accurate detection results. Compared with the traditional high-power coupling, the cost is lower, and there will be no iden...

Abstract

The invention belongs to the technical field of dangerous goods management, and discloses a dangerous goods management system and method based on RFID. The management system comprises an isolated storage cabinet which is a metal cabinet and is internally provided with a plurality of independent storage cavities, dangerous goods labels which are packaged or pasted on dangerous goods and store basicinformation of corresponding dangerous goods, a read-write device which is installed outside the isolated storage cabinet and mainly comprises a controller, a reader-writer, a wireless communicationmodule and a plurality of coupled antennas, and a PC which is wirelessly connected with the read-write device through the wireless communication module, acquires the data read by the reader-writer andprocesses and stores the data, wherein the coupled antennas are electrically connected with the reader-writer in a wired mode, and the coupled antennas are located in the independent storage cavitiesrespectively and form single pairing with the independent storage cavities. In conclusion, the system has the advantages of being efficient, safe, accurate in management effect and low in cost.

Description

technical field [0001] The invention belongs to the technical field of dangerous goods management, and in particular relates to an RFID-based dangerous goods management system and method. Background technique [0002] Dangerous goods is a general term for flammable, explosive, strongly corrosive and toxic items. There are strict regulations on the use, transportation and storage of dangerous goods, and they should be handled in accordance with the dangerous goods regulations. In traditional technology, enterprises usually use special warehouses to store dangerous goods, enter and leave warehouses manually or electronically, and double-person on-site signature confirmation, double-person on-site supervision and use. However, this management method mainly relies on human operation, which has potential security risks, opaque data, untraceable process, and unclear definition of rights and responsibilities. [0003] In addition, with the deepening of the application of the Inte...
