太阳能建筑一体化热水控制系统的研究
摘要
在我国应用于住宅建筑中的太阳能热水系统种类繁多,与建筑的匹配性相比,其控制形式较为单一,集成化程度不高。目前,我国城市住宅建筑的建设和发展以多、高层建筑为主,因此对太阳能热水系统在住宅建筑中的运用形式和规模提出了更高的要求,太阳能建筑一体化热水控制系统的研究也就决定了太阳能热水在城市建筑中的推广运用能否得到实现。
由于系统的集热效率、热量供应和运行稳定性等因素,如果依旧采用较为简单的控制方式,就无法很好的解决相关技术问题。本文根据集中供热、分户储热系统,研发一款太阳能热水控制器,采用PLC(总控制器)和单片机(分户控制器)结合的控制方式。PLC便于智能化集成监控与控制,运行稳定、可靠性高,与太阳能集热器、水泵、温度传感器、集热水箱和电磁阀等元件连接用于系统的集热,能实现热量的集中化供应。单片机体积小、功能强大、价格便宜,与家用水箱、电加热装置和分户电磁阀等装置连接用于系统的换热,在用水温度达不到要求时自动开启电加热,从而实现用户的个性化使用。两者结合能有效的提高集热效率和实现热量的合理分配。
本文重点阐述了热水控制系统(总控制器和分户控制器)的硬件电路设计和相关软件程序设计,并给出了具体的仿真实验结果。

RESEARCH ON BUILDING INTEGRATION OF SOLAR WATER HEATER CONTROL SYSTEM
ABSTRACT
There are many types of solar water heating systems used in residential construction in China, compared with the match of the building, control form is single and poor degree of integration. At present our country city residential building's construction and development, mainly in high-rise building, therefore the solar water heating system in residential architecture form and size has put forward higher requirements, the solar building integrated hot water control system will determine whether to achieve to promote the use of solar water heating in urban architecture .
Because of the system heat collection efficiency, heat supply, operation stability and other factors, if still adopt a simpler control method that can not solve the relevant technical problems. In this paper, according to central heating household heat storage system, developing a solar hot water controller , which using PLC (controller) and SCM (household controller) combined with control, PLC to facilitate intelligent integrated monitoring and control, which has stable operation and high reliability , connection with the solar energy heat collector, water pump, a temperature sensor, a heat collecting water tank, ic valve and ponents for the system solar collector . SCM has the advantages of smal
