Description

Cargo warehouse management method and system based on block chain

Technical Field

The invention relates to the technical field of logistics management, in particular to a block chain-based goods warehouse management method and system.

Background

In the field of production and processing, there are many enterprises with only production capacity and no storage capacity. Such businesses may be considered owners, who may seek partners with warehousing capabilities when the owners do not have warehousing capabilities. Meanwhile, the limitation of traditional warehousing should be broken when seeking warehousing merchants, and more warehousing merchants with idle warehousing capacity should be sought.

Meanwhile, with the development of the modern logistics industry, warehouses become important goods sources and goods distribution centers. However, the market development speed is too fast, so that the management system is not completed in time, meanwhile, related professional skills are deficient, and the market is frequently in vicious competition.

Meanwhile, people store the information of the product by using the bar code, and only the bar code needs to be scanned, so that the basic information of the product can be obtained. However, since the bar code is easily copied, the degree of forgery prevention for the product is not high. At present, the RFID technology is also used, so that the characteristic information reading during the warehousing, ex-warehouse and circulation of goods can be efficiently completed. As disclosed in chinese patent publication No.: CN111523836A, patent publication date: 2020.08.11, discloses a distributed warehouse management system based on internet of things technology and a management method thereof, which specifically comprises an industrial control all-in-one machine and a warehouse management system in communication connection with the industrial control all-in-one machine; the industrial control integrated machine comprises a power supply unit, a network unit, an RFID long-distance reader-writer and an RFID short-distance reader-writer, wherein the RFID long-distance reader-writer and the RFID short-distance reader-writer are used for wirelessly identifying RFID electronic tags arranged on tools; the warehouse management system comprises a control unit, a warehousing unit, a ex-warehouse unit, an inventory counting unit, an inventory early warning unit, an inventory information query unit, an inventory information sending unit and a voice unit; and a warehouse management system is arranged in the industrial control all-in-one machine.
