【摘要】：城市集中供热系统是城市经济建设和社会发展的重要基础设施，其发展水平代表着城市现代化的程度，发展节能和环保型的集中供热系统已成为城市供热的发展趋势。利用现代化的科技手段，建设远程智能集中供热系统是近年来人们追求的目标之一。 在参考大量国内外集中供热系统以及供热温度控制系统研究现状的基础上，介绍了供热系统换热站的组成、工作原理和供热调节方法；以曹妃甸集中供热系统为研究背景，设计了集中供热系统的组成和控制方案；应用模糊控制理论设计了换热站温度控制系统；以供水流量和室外温度作为输入，以回水温度作为输出，设计出了集中供热的二维模糊控制器。 在换热站温度控制系统研究的基础上，，设计了由热网监控中心、热力站监控系统和无线通讯系统三部分组成的远程集中供热监控系统。上级为监控中心，下级为各个热力站，通过3G无线网络将各热力站与监控中心相连，各部分协调工作，实现热网监控的各项功能。利用iFIX组态软件开发了监控中心上位机热网监控软件，该软件具有现场实时数据监控功能，不仅可以显示一次网和二次网的供回水温度、压力、流量等设备运行参数，还具有对现场设备进行异常和故障监测，显示实时报警数据以及打印报表等功能。 该供热智能控制系统已投入实际应用，效果良好，达到了降低能耗、提高经济效益的目的。
[Abstract]:Urban central heating system is an important infrastructure for urban economic construction and social development. Its development level represents the degree of urban modernization. The development of energy-saving and environment-friendly central heating system has become the development trend of urban heating. It is one of the goals that people pursue in recent years to construct remote intelligent central heating system by means of modern science and technology. On the basis of referring to a large number of domestic and international central heating systems and the research status of heating temperature control system, the composition, working principle and heating regulation method of heat exchange station of heating system are introduced. Based on the research background of Caofeidian central heating system, the composition and control scheme of central heating system are designed, and the temperature control system of heat exchange station is designed by using fuzzy control theory. A two dimensional fuzzy controller for central heating is designed by taking the water supply flow and outdoor temperature as input and backwater temperature as output. Based on the research of the temperature control system of the heat exchanger station, a remote central heating monitoring system is designed, which is composed of three parts: the monitoring center of the heat network, the monitoring system of the thermal station and the wireless communication system. The superior is the monitoring center and the subordinate is each thermal station. Through 3G wireless network, each thermal station is connected to the monitoring center, and each part coordinates the work to realize the various functions of the heat network monitoring. Using iFIX configuration software, the monitoring software of upper computer heat network in monitoring center is developed. The software has the function of real time data monitoring on the spot. It can not only display the temperature, pressure and flow rate of the primary network and secondary network, but also display the operation parameters of the equipment, such as temperature, pressure, flow rate and so on. It also has the functions of abnormal and fault monitoring, displaying real-time alarm data and printing report forms. The intelligent heating control system has been put into practical application, and the effect is good. The purpose of reducing energy consumption and increasing economic benefit is achieved.
