【摘要】：近年来，由于集中供热具有节约能源、改善城市基础设施状况以及改善环境污染等方面的优点，，所以在我国得到了迅速的发展。到目前为止，已经有360多个城市实现了集中供热。然而，我国大部分城市的集中供热系统的运行、维护以及管理的自动化水平以及信息化程度还比较低。本文针对集中供热系统在运行、管理、维护等环节存在运行效率很低、供热质量较差、节能效果不理想等问题提出改进措施，并结合物联网技术设计并实现了高效节能的集中供热网络系统。该系统已经在天津市南开区、东丽区等地区得到成功应用，数据显示运行效率增加，供热质量提高，节能效果明显。 首先，本文分析了传统集中供热网络系统存在的问题，提出了基于物联网技术的集中供热节能网络系统及其结构，即通过物联网技术，将换热站、工作人员、控制中心与互联网相连接，组建成一个完整的集中供热节能网络系统，该系统包括换热站现场控制、控制中心以及通讯网络三个部分，这三部分的关系概括来说，是控制中心通过通讯网络对所有的换热站进行远程监控调节。 然后，通过对多种通讯方式进行比较分析，本文采用GPRS无线传输方式进行数据通讯，并且设计了通讯网络系统，通过通讯网络系统实现了换热站与控制中心之间的数据通讯，包括采集数据的上传，控制信息的下发以及控制应答信息回馈。 其次，本文设计了换热站监控子系统，实现了控制中心对换热站的实时远程监控。并且，通过对气象数据、用户的用热特点、建筑类型对供热的影响的分析，本文提出了换热站节能运行控制模式，具体包含三个部分：换热站分组分段控制策略、基于室内温度反馈的控制曲线动态调节策略及换热站运行控制曲线辅助决策。 最后，针对集中供热系统的突发情况，本文提出了短信报警服务，并且设计实现了基于GSM/SMS的短信报警服务平台。即在传统的集中供热报警方式基础上，增加了短信报警功能，通过短信来将报警信息实时发送给工作人员；另外还增加了短信服务功能，通过短信方式来查询和设置换热站的运行数据及控制参数。
[Abstract]:In recent years, central heating has been developed rapidly in China because of its advantages of saving energy, improving urban infrastructure and improving environmental pollution. So far, more than 360 cities have achieved central heating. However, the level of automation and informatization of central heating system in most cities of our country is still low. In this paper, the improvement measures are put forward to solve the problems of low running efficiency, poor heating quality and poor energy saving effect in the operation, management and maintenance of central heating system. Combined with the technology of Internet of things, a high efficiency and energy saving central heating network system is designed and realized. The system has been successfully applied in Nankai District and Dongli District of Tianjin. The data show that the efficiency of operation is increased, the quality of heating is improved, and the effect of energy saving is obvious. Firstly, this paper analyzes the problems existing in the traditional centralized heating network system, and puts forward a centralized heating energy saving network system and its structure based on the Internet of things technology, that is, through the Internet of things technology, the heat exchange station, the staff, The control center is connected with the Internet to form a complete centralized heating energy saving network system. The system consists of three parts: field control of heat exchange station, control center and communication network. The relationship between these three parts is summarized. It is the control center through the communication network to all the heat exchange station remote monitoring and adjustment. Then, through the comparison and analysis of various communication modes, this paper adopts GPRS wireless transmission mode to carry on the data communication, and designs the communication network system, realizes the data communication between the heat exchange station and the control center through the communication network system. Including the collection of data upload, control the sending of information and control response information feedback. Secondly, the monitoring subsystem of heat exchange station is designed in this paper, and the real-time remote monitoring of heat exchange station is realized. In addition, through the analysis of meteorological data, the characteristics of users' heat use and the influence of building type on heating, this paper puts forward the energy saving operation control mode of heat transfer station, which includes three parts: the heat transfer station group division control strategy, Dynamic adjustment strategy of control curve based on indoor temperature feedback and auxiliary decision of heat transfer station operation control curve. Finally, in view of the emergency situation of the central heating system, this paper puts forward the short message alarm service, and designs and implements the short message alarm service platform based on GSM/SMS. That is, on the basis of the traditional central heating alarm mode, the text message alarm function is added to send the alarm information to the staff in real time through the short message; in addition, the short message service function is also added. The operation data and control parameters of heat exchange station are queried and set by short message.
