【摘要】：近些年来,建筑节能已经成为我国节约能耗的重要一环。然而,当下我国存在的供热收费体系的不合理,不仅不能调动居民节能的积极性,而且由于室温的过热存在开窗换气的能源浪费现象。严重阻碍了我国建筑节能事业的健康发展。为了推动我国建筑节能事业的蓬勃发展,本文提出了一套基于热分摊法的供热计量系统,该系统不仅能够公平、合理、准确分摊用户用热量,而且能够促进居民的节能意识,为我国节能事业做出自己的贡献。首先,本文介绍了该供热计量系统的理论基础热分摊法,对它进行了理论的推导,证明了理论的正确性,同时对异常情况下热分摊法进行了修正,并且对修正后的方法进行数据与仿真分析。其次,进行了供热计量系统整体方案的设计。供热计量系统的热计量装置包括:室内温控器、通断控制器、采集计算器、楼栋热量表。本文主要进行了室内温控器与通断控制器的硬件与软件设计,同时进行了通信格式的设计以及供热管理系统监控界面的设计。主要硬件设计模块包括:电源模块、按键模块、显示模块、射频模块、测温模块、指示灯模块、电机控制模块、断电模块、RS485模块、防盗模块及存储模块;监控界面设计模块包括:登陆界面、供热管理界面、用户用热报表界面。最后,进行了供热计量系统的可靠性设计,其中包括:热计量装置之间的通信的可靠性设计:通过跳频策略避免WLAN设备干扰;室温调控策略的可靠性设计:通过BP神经网络对控制周期内阀门开启时长进行预测,通过模糊控制器实现对室内温度的恒温控制;管网工况的可靠性设计:提出通过交错控制周期实现工况的稳定控制。本文研究设计的供热计量系统响应国家提倡的建筑节能政策,可以在实现用户用热舒适性及企业盈利的前提下,有效的促进居民的节能意识,在今后的供热领域中必将占有重要的一席之地。
[Abstract]:In recent years, building energy saving has become an important part of China's energy consumption. However, the heat charging system at present in China is not reasonable, not only can not mobilize the enthusiasm of the residents of energy-saving, but also because of the energy wasting phenomenon at room temperature overheating existing window ventilation. Seriously hindered the healthy development of building energy conservation in our country. In order to promote the vigorous development of building energy conservation in our country, this paper puts forward a set of heating metering system based on heat allocation method, the system can not only fair, reasonable, accurate allocation of heat users, but also to promote energy-saving awareness of the residents, to make their own contribution to China's energy conservation. First, this paper introduces the theory of thermal the heating metering system allocation method, the theoretical derivation proves that the theory is correct, and the thermal allocation method under abnormal condition has been revised, and to repair The method is used to analysis the data and simulation. Secondly, the overall design of heating metering system. Heat metering device of heat metering system includes indoor thermostat, on-off controller, acquisition calculator, building heat meter. In this paper, the hardware and software design of indoor thermostat and on-off controller, at the same time the design of communication format and design management system monitoring interface. The main hardware modules include: power module, keyboard module, display module, RF module, temperature measurement module, indicator lamp module, motor control module, power module, RS485 module, security module and memory module; the monitoring interface design include: login module interface, heating management interface, the user interface of the highest form. Finally, the reliability design of heat metering system including: heat metering device is arranged between the reliability of communication. Design: WLAN devices to avoid interference through frequency hopping strategy; reliability design of temperature control strategy of long period prediction control valve opening by BP neural network, through the realization of constant temperature of the indoor temperature control fuzzy controller; reliability design working condition: put forward through the cycle stability control is realized under interleaving control. Building energy policy state advocate response heating measuring system designed in this thesis, the user can be realized in the premise of thermal comfort and enterprise profit, effectively promote energy-saving awareness of the residents, will occupy an important field in the future in a space for one person in the heating.
