Research And Implementation On Monitor And Control For The Heat-supply Network Based On LBS

With the increasing seriousness of fog,the environmental management is urgent.Compared with the small boiler heating,central heating can better provide the heating quality,reduce energy waste and pollution.How to integrate the LBS into the monitoring system,making the monitoring and management of the heating network no longer subject to geographical restrictions,and using the positioning technology of the mobile client,combining with visualized geographic information system,in order to develop a more convenient information management system of heating network,is the focus of this thesis.This thesis is supported by Educational Commission of Hebei Province of China(ZH2012066).On the basis of analyzing SCADA monitoring system of the host computer from a energy company.A information management system of heating network based on LBS with the MVC architecture on the Android mobile platform is designed to expand the mobility of the heating network monitoring system.The B/S combined with C/S mode is adopted,and a data access interface is set up.First of all,this thesis deeply studied the components and operation modes of the central heating network,and the data interaction process.The working habits of the users of the heat network information management system and the development needs are surveyed.A reasonable system function and the system architecture are designed.Secondly,according to the system information collection point and design function.A SQL Server database with clear relationship between the data table structure is created.This thesis deeply studies the construction and distribution of WebService,the features and advantages of XML text,the interaction of mobile terminals and the underlying data,then set up a WebService to convert database data into XML text for mobile terminal calls.Finally,this thesis constructs the program thread of mobile terminal with the idea of MVC frame structure in Android environment,mastering the basic knowledge of GIS map construction,exploring the application mechanism of BaiduMap API and developing the visual LBS function,including thermal display,checking attendance,visualization network based information query,and other functions,also has realized the real-time operation data of heating pipe network system monitoring,historical data query and statistical analysis.Through the real machine test,the results show that the system can run smoothly.Improve the convenience and mobility of heating monitoring platform,realizes the intelligent network control,has wide application prospect.
