Development And Research Of Cotton Distribution Trading System Based On Cloud Platform

Cotton is a commodity and an important strategic reserve resource.At present,The low level of information in production and trading and supply and demand information are not transparent,result in a large amount of cotton backlog and unbalanced supply and demand.Cotton circulation process is more,divided into seed cotton acquisition,cotton storage,transfer library,stocking,sales and transportation and other links.In order to promote the circulation efficiency and reduce the cost of cotton products,the paper comprehensively analyzes the business processes and functional requirements of the cotton circulation transaction.Based on the B/S framework and distributed multi-tier architecture,the paper proposes a B/S based on the Azure cloud platform.Framework and distributed multi-layered architecture of the cotton circulation trading system framework,and gives a specific method of implementation.The main research work of the dissertation includes:(1)According to the characteristics of cotton quality data management,we designed a web crawler based on depth-first search,which can get cotton quality data automatically,and exploratory analysis of cotton quality data is performed.Through analysis,we found that the distribution of length and length uniformity of cotton fiber was more uniform between 2017 and 2016,while the extreme value of the fracture strength was increased and the moisture regain was reduced.(2)Based on the distributed multi-tiered architecture and Azure cloud platform,the system framework of cotton circulation trading based on the B/S model was constructed,and the cotton circulation transactions covering data acquisition,storage,transfer,sales,settlement,and transportation were given.The system implementation method of each link.(3)In order to strengthen the security of the system,based on role-based access control,physical UKey authentication is adopted for important roles to ensure the legality of logged-in users.Considering the special situation of system deployment,the synchronization mechanism based on the remote Azure storage platform was designed.This paper is aimed at many links in the cotton circulation trade.The software system developed has been put into practical use by the Eighth Division of Xinjiang Production and Construction Corps,effectively improving the efficiency of the cotton circulation transaction and realizing the important data and documents in the system and the remote Azure cloud platform.Automatic synchronization.
