Research And Implement Of An Intelligent Express Storage System Based On Internet Of Things

With the development of Internet of things technology and the improvement of the quality of people's lives,the human society will come into a new era of intelligent,the rise of the "Internet of things" play an important role to the full integration of logistics information.In the face of logistics,express delivery business explosive growth,"the Last 100 meters" distribution has become the key factor of restricting the delivery efficiency.According to the electrization,automation and integration irresistible general trend of modern logistical industry,Based on the Internet of things technology,this paper puts forward an intelligent express storage system,which puts the information identification,telecommunications,automatic control and other electronic science and technology together,leads and meets people fast,convenient,low-cost logistics spending lifestyle.Therefore,it can make the logistics management automated and high efficient.The cost has been reduced and service quality has been improved.The waste of natural and social resources has been reduced.The main content of this paper is as follows:Firstly,this paper introduce the RFID technology into the information collection.In the case of RFID multi-tag anti-collision,for application limited of DFSA and the collision problems caused by the large number of tags in grouping DFSA,and by analyzing the tag distribution under optimal recognition efficiency,a new anti-collision algorithm of dynamic frame slotted ALOHA based on hash function grouping is proposed.The new algorithm reduces the total slots and collision slots,and the identification efficiency of system has significantly improved.Secondly,it is use 3G wireless transmission technology to in data transmission.It is profits from POCKET theory,data communication contract has been made to ensure the security of data interaction,which includes frame head,type,number,number USIM,time,data and work number/password,status,calibration,frame,etc.With the data communication contract,data transmission has been more security.With ASR-ARQ technology,data transmission has been more safety and Veracity.Finally,this paper gives an analysis on demand of the intelligent logistics storage system,using RFID technology,sensor technology,wireless network technology,it constructs the architecture of the overall system,which includes data collection module,system control Module,data storage and interaction module.Following the principle of high-speed circuit design,the system aims at high speed,stable system and sound function.It use Mainstream ARM7 core processor,the electric circuit includes crystal oscillator circuit,reset circuit,JTAG debug circuitry,Real-time clock circuit,Power management circuits,gate switch control circuit,external printer circuit,etc.Based on the software engineering ideas it achieves the main function of logistics storage,according to the orders,it stores the goods,and sends the message to the client,then the client get his goods.
