【摘要】：當前，我國建筑能耗不斷增加，采暖能耗在建筑能耗中的比例也越來越大。集中供熱是我國采暖的主要方式，提高集中供熱能源利用效率對我國建筑節(jié)能意義重大。隨著采暖面積的不斷增加，供熱管網(wǎng)呈現(xiàn)出從單熱源支狀管網(wǎng)向多熱源環(huán)狀管網(wǎng)發(fā)展的趨勢。同時，隨之產(chǎn)生的供熱管網(wǎng)設計不合理、水力失調嚴重等問題一直得不到解決。地理信息系統(tǒng)(GIS)是近些年飛速發(fā)展的新技術，在城市地下管網(wǎng)領域應用越來越廣泛。但是地理信息系統(tǒng)在供熱管網(wǎng)方面的應用相對較少。目前，國內外關于將地理信息系統(tǒng)應用于其它城市地下管網(wǎng)的研究已經(jīng)有很多成果。利用其它城市地下管網(wǎng)與地理信息系統(tǒng)結合的應用經(jīng)驗，結合供熱管網(wǎng)的特殊性，研究地理信息系統(tǒng)在供熱管網(wǎng)中的應用有重要意義。 本文首先通過研究供熱管網(wǎng)設計水力計算的理論和方法，應用圖論和矩陣理論，建立了供熱管網(wǎng)的數(shù)學模型。總結了支狀管網(wǎng)和環(huán)狀管網(wǎng)的設計水力計算流程，利用基本回路法對數(shù)學模型進行了理論求解。最后通過數(shù)值迭代的方法完成了計算機上的求解，并利用Visual C++編程語言編寫了程序模塊，該模塊可以對不同形式的供熱管網(wǎng)進行設計水力計算和水力工況分析，如支狀和環(huán)狀管網(wǎng)，單熱源和多熱源管網(wǎng)。 其次，通過研究地理信息系統(tǒng)二次開發(fā)，分析供熱管網(wǎng)的結構特點，結合MapGIS地理信息系統(tǒng)的圖形操作和空間數(shù)據(jù)分析功能，利用Microsoft Office Access數(shù)據(jù)庫和MapGIS-SDE空間數(shù)據(jù)引擎，，建立了供熱管網(wǎng)地理信息系統(tǒng)關系數(shù)據(jù)表和圖形文件。之后，研究了GIS的圖形操作和空間分析方法，采用遍歷算法完成管網(wǎng)的拓撲結構搜索，建立供熱管網(wǎng)拓撲矩陣。得到拓撲矩陣后便可以代入水力計算模塊進行水力計算。 最后，對比分析供熱管網(wǎng)和其他城市地下管網(wǎng)的特殊性，提出在設計水力計算時采用供水管網(wǎng)建立拓撲圖進行計算，在工況分析時采用供回水管網(wǎng)建立拓撲圖進行計算的方式。在供熱管網(wǎng)地理信息系統(tǒng)水力計算功能的基本框架內，進行了其他功能的拓展理論性研究，包括利用GIS對管網(wǎng)進行實時查詢、在線監(jiān)測、管網(wǎng)維護、事故分析等。
[Abstract]:At present, building energy consumption in China is increasing, heating energy consumption in building energy consumption is also increasing. Central heating is the main way of heating in China. It is of great significance to improve the energy efficiency of central heating for building energy conservation in our country. With the increasing of heating area, the heat supply network is developing from single heat source branch network to multi heat source ring pipe network. At the same time, the problems of unreasonable design and serious hydraulic maladjustment have not been solved. Geographic Information system (GIS) is a new technology developed rapidly in recent years, which is widely used in the field of urban underground pipe network. But the application of GIS in heating network is relatively few. At present, there have been a lot of achievements in the application of GIS to underground pipe networks in other cities at home and abroad. It is of great significance to study the application of geographical information system (GIS) in heating pipe network based on the application experience of other cities' underground pipe network and geographic information system (GIS) and the particularity of heating network. Firstly, by studying the theory and method of hydraulic calculation in the design of heating network, the mathematical model of heat supply network is established by using graph theory and matrix theory. The design hydraulic calculation flow of branch pipe network and annular pipe network is summarized, and the mathematical model is solved theoretically by the basic loop method. Finally, the computer solution is completed by numerical iteration method, and the program module is compiled by Visual C programming language. The module can be used to design hydraulic calculation and hydraulic condition analysis for different forms of heating pipe network. Such as branch and ring pipe network, single heat source and multi-heat source pipe network. Secondly, by studying the secondary development of GIS, analyzing the structural characteristics of heating network, combining the graphic operation and spatial data analysis function of MapGIS GIS, using Microsoft Office Access database and MapGIS-SDE spatial data engine, The relation data table and graphic file of the heating network GIS are established. Then, the graph operation and spatial analysis method of GIS are studied, and the topology matrix of heating network is established by using traversal algorithm to search the topology structure of the pipe network. The topological matrix can be replaced by hydraulic calculation module. Finally, by comparing and analyzing the particularity of heating network and underground pipe network in other cities, it is put forward that the topology chart of water supply network should be used in the design of hydraulic calculation, and the topology chart of supply and return water pipe network should be used for calculation in the analysis of working conditions. In the basic framework of hydraulic calculation function of heat supply network geographic information system (GIs), theoretical research on other functions has been carried out, including real-time query, on-line monitoring, pipe network maintenance, accident analysis and so on using GIS.
