Research On Railway Warehouse Information Collection System Based On Internet Of Things

Railway transportation has always been the first choice for transportation of goods with large volume and long distance,and warehousing is an important part of railway logistics.In order to speed up the construction and improve the management efficiency,this thesis puts Internet of Things key technology into management,with the railway electronic identification system to a certain extent,replaces the traditional manual work.The work of the process encountered in the collision problem of further study,and builds the experimental environment and tests analysis.Firstly,the thesis introduces the current development of railway logistics,analyzes the advanced mode management at home and abroad and explains the importance of railway warehousing information.Then,analyzes the key technologies such as RFID and wireless transmission used in the process of information collection,and expounds the feasibility of information technology.Secondly,the thesis describes the specificity of the railway storage environment and the planning of the reservoir area.Based on the common warehousing operation process and the key technologies of the Internet of Things,designes the process from the station,warehousing,storage,out of stock,processing,distribution of links.It introduces the tags information transmission process details,and designs the collection and transmission of the topology.Thirdly,a study on the collision of information caused by intensive reading of electronic tags,the thesis analysis of several basic TDMA algorithms in comparison then chooses the advantages of query tree algorithm from time complexity,communication complexity and recognition rate.The binary-quaternary query tree combined with the dynamic frame time slot Aloha algorithm as an anti-label collision algorithm for railway warehouse,and improves the algorithm by simulation and analyze the results.Finally,according to the experimental need to build simulated warehouse test environment,introduces the main equipment functions and principles.The improved algorithm is applied to verify and test the practicality.Informatization and automation are the inevitable trend of railway logistics development.Application of Internet of Things technology to improve the efficiency management can play the scale,enhance operational efficiency,better adapt to changes in market demand structure,and constantly open up the transport market.
