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

With our energy reduction "12th Five-Year Plan" proposed expanding the scale of the city,the central heating demand more flexible, how to make full use of heating resources, improve theheating efficiency become increasingly prominent social issues. Therefore, the need tounderstand the real-time status of the heating pipe network, dynamically adjust the balance ofheat supply network, real-time control of the heating system, both to meet the real-time changesin user requirements, but also to save heating energy to achieve energy saving needs.First of all, the heating monitoring and management system based on GIS geographicinformation, map information software rely on real-time rendering monitoring within the heatingpipe network, to provide a more reliable method of monitoring for managers. MapXtreme mapdevelopment software introduced into the heating monitoring system using map the geospatialcoordinates simulation show heating pipe network step-by-step toward accurately show theheating parts location, the heating pipe network laying work and parts repair and replacementwork more convenient.Second, using the Modbus protocol to establish a communication channel, the heatingmonitoring system with a heat transfer station lower machine data communications, themonitoring center capable of real-time monitoring of the heat transfer station heating parameters;remotely adjust the heat transfer station heating parameters, monitor alarm informationinformation and the equipment is running, the more energy efficient central heating, security andstability.Finally, to improve the efficiency of the system is running, by using Ajax technology,enables users of map operation efficient response; classification freeze and Quartz timing data, toimprove the user’s query and response time statistics. And according to the thermodynamicformula to calculate the statistics show, curves, bar charts, tables, and other forms of statisticalfunctions provide convenient query functionality and data.The system has been successfully applied to the management of multi-city heating, runningwell, convenient user heating monitoring remotely adjust to achieve the purpose of energysaving.
