Product transportation management method on basis of radio frequency technology and Hash algorithm

Abstract

The invention relates to the field of radio frequency identification technologies, and discloses a product transportation management method on the basis of a radio frequency technology and a Hash algorithm. The product transportation management method includes steps of distributing an RFID (radio frequency identification) tag for each goods unit, and storing goods information and the RFID tags in a remote goods inspection center; sequentially loading the goods units; reading EPCs (electronic product codes) according to a loading sequence, merging the EPCs, generating Hash codes from the merged EPCs by a Hash function, and storing the generated Hash codes in the remote goods inspection center; delivering the goods units to destinations and unloading the goods units; sequentially reading the EPCs, merging the EPCs, generating Hash codes from the merged EPCs by the Hash function, and storing the generated Hash codes in the remote goods inspection center; enabling the remote goods inspection center to verify the Hash codes, completing entry to a transportation management procedure if the Hash codes are successfully verified, or entering an investigation procedure if the Hash codes fail in verification. The product transportation management method has the advantage that the sequence of the goods units can be effectively and efficiently verified by the aid of the Hash algorithm.

Description

technical field [0001] The present invention relates to radio frequency identification technology (RFID), embedded software development, remote server software development technology field, especially a product transportation management method based on radio frequency technology and hash algorithm. Background technique [0002] As one of the key technologies for the development of the Internet of Things, radio frequency identification technology (RFID) has developed rapidly in recent years. It has been widely used in product verification, traceability and other fields, which can significantly improve the inventory of goods. Efficiency and reduced theft rate etc. [0003] At present, the more common method of using RFID to inspect goods is to attach an RFID tag to each cargo unit (for example, a box or a bag of goods as a cargo unit, etc.), because the label has a unique product electronic code (EPC) code), so it can be used as the only basis for the identification of goods....

AI Technical Summary

Problems solved by technology

[0004] However, this RFID-based goods inspection method still has its limitations. In some special cases (especially in the field of valuables transportation), it is necessary to verify the order in which the goods are placed. If only the above-mentioned method is used for inspection, Since the reader reads the contents of all the tags within its recognition range at one time, and the receiving process is out of order, it is impossible to verify whether the order of placing the goods has changed

However, if it is adopted to read the cargo units one by one and verify whether their positions are correct one by one, this method will carry out an inspection process every time an inspection unit is read, which is inefficient and expensive for the verification system, which is clumsy and uneconomical
