The Design And Implementation Of The Gas Management System Based On Web And Security

With the progress of the country and development of the city.The improvementof the city construction level has continued to rise,also the demand of clean energyis increasing fast.Our gas enterprises have concentrated on the development anddesign of enterprise management information system since90’s of20th, but theywill not adapt to the custom oriented operation philosophy in the day which gasindustry becoming increasingly competitive.Traditional gas enterprise management information systems are mostly siledapplications, can only solve the gas management system of a certain part, eachsystem is developed by different companies, and between systems is not a unifiedspecification, data sharing, system upgrades become very difficult, therefore, theyare eager to have a a unified information service platform that face gas company andfor the end.To solve the above problems, For the demand of enterprise information forsecurity. This paper put forward a comprehensive gas management system,whichunified date collection、 check、 save and analysis.At the same time to meet therequirements of enterprise information on security, this paper also designs andimplements the high-level system security model. The main contribution of thisarticle is as follows:1. The thesis studies the gas industry background and developmenttechnologies of system.The system include two subsystems: one is the design andimplementation of the gas data acquisition system based on the Internet things.Thegas data acquisition system by means of terminal equipment of digital instrumentsent to the data to data acquisition station through Field bus.The data acquisitionstation through the GPRS network to transmit data to the server.The will be stored inthe database after the check,then the gas management system can analyses、aggregate、back up、integrate and mining the data.The other is the design and thedevelopment of the Meter data management center which based on J2EEdevelopment platform SSH.It is divided into four modules,in which the backstagemanagement center、operation control center、decision analysis center、customer carecenter are included.2. In order to ensure the information security of the system.The article finally build a access control right management model based on role, from different levelsof security analysis, the model put the safe strategy of the system,which ensure thesafe of the system and confidentiality of the data.At the same time the the userpassword Is not illegal to view and manipulate in the database.Above all, in thispaper, the MD5improve data transmission and database account informationsecurity by means of encryption of user passwords.
