摘 要

随着智能家居的发展，越来越多的智能化设备进入到普通家庭当中，在体验到智能家居带来的安全性、便捷性和舒适性的使用后，对于智能化设备需求量越来越大。

传统的供暖设备需要人为手动改变能量的供应，甚至有一些只能使用单种能源，如电热壁炉，使用限制多且使用体验不尽人意。所以设计开发一套能够使用多种能源且能够智能调控能源使用并自动控制室温的供暖系统，以达到多选择性和安全、经济和便捷的供暖使用体验。

本设计是基于虚拟仪器LabVIEW软件，设计智能家居能源控制系统，通过数据采集卡USB-6008采集光伏电池的输出电压，以及室内环境温度和水箱温度，设计一套智能家居太阳能与电能、天然气联用的供暖系统。实现能源的高效利用以及更为经济的供暖方案。

Abstract

With the development of intelligent home, more and more intelligent equipment get into ordinary families, have experienced the security, convenient and comfortable use of intelligent home equipment, the demand of intelligent equipment be higher.
The traditional heating equipment need to manually change the supply of energy, even some can only use one kind of energy, such as electric fireplace, there are restrictions on the use of and unsatisfactory experience. Therefore, design and develop a set to be able to use a variety of energy and can intelligent control energy use and automatic control of the temperature of the heating system, so as to achieve more selective and safe, economic and convenient use experience.
The design is based on the virtual instrument software LabVIEW, design the smart home energy control system through a data acquisition card, use usb-6008 to acquire the output voltage of photovoltaic cells, and the indoor temperature and the temperature of the water tank, design a set of intelligent household solar energy and electric energy, natural gas combined heating system. Design an efficient use of energy and more economical heating scheme.

 Key Words: heating system; intelligent control; economy; Photovoltaic cells
