Design And Implementation Of The Information Management Subsystem Of Food Traceability System

Information technology innovation and rapid development of information industry information transparency and speed of dissemination,consumers pay more and more attention to food safety information.With the emergence and development of mobile network,consumers can realize food information traceability by using the linkage between the special software of mobile phone terminal and the food traceability information platform.The realization of food information traceability depends on Internet of things technology,traceability code technology and high speed information communication technology.This paper mainly studies the related contents of traceability information management in the food traceability information platform,aiming at constructing a food traceability platform in which many enterprises in the food industry participate and share data.Including the mobile phone terminal special software and traceability information management subsystem,mobile phone terminal special software is responsible for scanning code and transmitting consumer traceability request.Traceability information management subsystem mainly realizes food traceability data collection.Food traceability information management,traceability code identification and traceability code construction and other business functions.Based on the actual needs of food enterprises,the paper consulted the re levant references of traceability technology and traceability system,and fully analyzed the main business processes of food traceability.The design and im plementation of traceability information management subsystem of food tracea bility system are studied.The core technologies adopted include traceability c ode technology and SSH technology.With the introduction of traceability cod e technology,all foods have unique anti-counterfeiting coding SSH technology.The purpose of this technology is to build traceability information managem ent subsystem for traceability users quickly.Based on the analysis of all functions and performance requirements of food traceability,the functional structure of food traceability information mana gement subsystem is designed,including food information management and lo gistics data management.Traceability process management and system manage ment and other main modules.The system adopts three layers architecture ba sed on MVC,including data storage layer,business logic layer and service pr esentation layer,and uses TCP and HTTP technology to realize communicatio n.According to the architecture and related technology,this paper designs an d implements each module of the system in detail,and gives the core algorit hm,main data structure and key classes of food traceability.In order to verify the effectiveness and usability of the food traceability information manageme nt subsystem,not only the functional links of food traceability are fully teste d,but also the performance of the system is verified.The test results show t hat,The food traceability information management subsystem designed and re alized in this paper has reached the target set in demand analysis in function and performance,and has been running in some pilot enterprises.Meet the basic requirements of enterprise food traceability,can be popularized and appl ied in batch.
