Design And Implementation Of Mobile Terminal Of Ethylene Production Energy Efficiency Monitoring And Evaluation System

Ethylene production energy efficiency monitoring and evaluation system platform is an important tool to improve energy utilization efficiency and reduce emission for ethylene production enterprises.At present,the platform has achieved good results by applying in an ethylene production enterprise.However,the monitoring of data and the display of results of energy efficiency indicators are all carried out at computer terminals on the platform,which makes,it difficult for users of the platform to leave their office.And it has imposed significant restrictions on petrochemical companies to conduct energy efficiency monitoring and evaluation and diagnosis on a larger scale and in a larger scale.With the rapid development of smart mobile terminal devices and mobile internet technologies,more and more traditional software starts moving toward mobile terminals.It makes it possible for the platform to move to the mobile side.To provide convenience for the platform users,this paper designs a platform and implements the mobile terminal of the ethylene production energy efficiency monitoring and evaluation system.Based on the C/S mode,the system is mainly composed of server,Android client and database.The server side mainly completes the data from the original platform database,and processes the data to process the data format required by the Android system;the data and image display are completed in the Android client.And the data display is divided intohistorical data dispaly and real-time data display.Chart display is completed with Android third-party open source library MPAndroidChart;the database is divided into server-side database and Android client database.On the server side of the database,the data obtained from the original platform is mainly stored as a backup for the data required by the Android client,and the data transmitted from the Android client is received.In the database of the Android client,it is mainly to cache the historical data of the energy efficiency indicator,the operation log data,and the system user information data for a period of time.In the implementation process of the platform,the server mainly uses the servlet technology in java development.The servlet interacts with the database,which can realize the function of browsing and modifying the data in the database.Through network communication,the data in database can be obtained on the mobile terminal;the server-side database uses the Oracle database,the mobile-side database uses the SQLite database that comes with the Android system;the programming language of the entire system is platform-independent java language.The network communication library used between the server and the Android client is OKHttp3,the JSON format used by the data interaction format.In the whole system,the server-side development is performed on Eclipse;the Android-side development is performed on Android Studio;the application test in smartphone.After the final functional and non-functional tests,it can be concluded that the system can perform our intended functions and run smoothly on the phone.
