The Design And Implementation Of Tobacco Storage Safety Monitoring System

The value of tobacco economic is far higher than that of agricultural products,and it is also a kind of tobacco storage environment requires high commodity,the State Tobacco Monopoly Bureau issued a series of management measures,management measures such as the introduction of the National Tobacco preservation of the tobacco storage room construction standard,tobacco storage in detail the provisions and specific requirements and many aspects of maintenance standards,pest control,fumigation safety etc..But after investigation,it is found that there are many problems in the monitoring of tobacco warehouse storage environment,such as shortage of hands,paperless records,hard real-time detection and so on.Therefore,it is necessary to design a tobacco storage safety monitoring system to improve the comprehensive information level of the tobacco industry and optimize the allocation of work division.This thesis combined with the development of technology,client server development technology,design and implementation of the tobacco storage safety monitoring system and carried out the research of temperature warning function,carried out during the following several aspects of the design and research work:(1)The tobacco storage on-site observation,combined with the user demand,the overall framework of the use of WebService technology and SSM server framework client technology to design the tobacco storage safety monitoring system,the structure decomposition,the design and Realization of Web based Service server and client based on the SSM framework,and using the research methods of genetic algorithm optimization of BP neural network storage site environmental temperature warning on tobacco.Platform functions closely integrate user needs,including storage environment real-time detection,timing monitoring,historical data traceability,tobacco warehouse storage and storage personnel information modification,GIS geographic information location and other functions.(2)The function and performance requirements of the server side are analyzed,interworking and easy to expand system server and client.In the server development,we use Web Service as the server framework of tobacco measurement and control system.We design the location server resources,design network data transmission format,and process response information.From the perspective of information security,will not use the decrypted data interactive information exchange information between the client and server,the system uses two kinds of encryption methods,one is the encryption protocol SSL based on HTTPS,using the HTTPS data transmission in interactive information to ensure the safety of information;the second is to use MD5 and SOLT combination of encryption also,safe and reliable encryption in this way.The data transmission format is mainly used in JSON format with small volume and simple codec,which improves the information processing speed of the server and the Web Service.Client development has designed and implemented a client with a good interactive and fully functional tobacco storage safety monitoring system for the user.The SSM framework is the main framework of client development,which reduces the system coupling,improves the maintainability of the client and the reutilization of the code.(3)The tobacco storage environment temperature early warning research and simulation,the use of genetic algorithm to optimize neural network for real-time prediction of environmental temperature,reached early warning before the temperature exceeds the threshold value.Compared with traditional single BP neural network prediction,genetic algorithm optimizes the initial weights and threshold randomness of neural network,and makes the optimized Back network tend to be reasonable and stable.The system server is stable and efficient,the code structure is clear and easy to expand,the client runs smoothly,and the interaction is strong.At this time,the system server and the client have been used on a domestic tobacco companies.After the operation of the feedback management system of a domestic tobacco companies administrator,the modules run smoothly and can meet the needs of production.
