Abstract：In this article, we can realize the function of home lighting control, security alarm and remote monitoring which is based on the PLC automatic control technology, upper computer, GSM module and infrared sensor. First of all, this research can achieve single family lighting control and the combined control according to specific requirements, in order to adapt the needs of daily use. Then, by the infrared sensor and GSM module, the system can realize buzzer alarming. At the same time, system can also send alarm messages to the designated mobile phone. Finally, through installing sunflower software at mobile phones and computers which connected to the internet, we can control the Upper computer based on mobile phone, therefore remotely monitor PLC. In conclusion, this research completed control of the smart home and further improved the comfort and security of smart home.

1. 引言

如今，我们身处在一个高速发展的时代，人们越来越需要智能家居系统来改变传统家居。上个世纪80年代，智能家居在日本和欧美开始兴起。然而我国直到 90年代末才出现的智能家居。智能家居是以住宅为平台，通过物联网，PLC技术将各类传感器和家中的各种电器连接到一起，实现诸如家电开关控制、照明系统控制、防盗报警系统、远程监控等多种功能。传统的家居无法对家电，灯光进行智能控制，也无法远程监测住宅遇盗，更不能远程发送报警短信。智能家居相对而言，不仅能保障基本的住宅要求，而且能使家庭设备自动化，保证居住安全并智能报警，提高了家居生活的安全性。用户在能更好的控制家居的同时，也能减少家庭日常能源的方面开支。智能家居系统，是一个具有安全、舒适、便捷、智能等特点的系统，能够充分为人类提供一个私人的生活场所，这是非常重要和有意义的，也是具有很高市场前景的研究^【1】。同时PLC具有使用维护方便、编程简单、可靠性高、抗干扰能力强等特点，可以通过简单明确的梯形图，将数以百计的可供用户使用的元件编入一个PLC内，来实现非常复杂的控制功能。将PLC技术加入智能家居控制系统，不仅能够监视并控制整个系统设备，同时能够完成对设备的就地控制。本文通过基于PLC技术对智能家居集中控制，实现照明控制与防盗报警的同时将个人电脑作为PLC的上位机，同时在个人手机上下载向日葵远程控制软件，从而对智能家居进行综合控制并能远程监控整个系统。本研究是想在保证安全便捷、节能环保的前提下，将家庭灯光控制、防盗报警和远程监控等功能集合到一个系统内，提高智能家居的舒适性和安全性。

1. 现状与发展趋势
   1. 国内现状

智能家居在中国已经发展了十几年时间，从人们最初的想法，到今天融入带我们的生活，这是一个艰难崎岖的过程。从最初的萌芽期，当时并没有出现专业的智能家居生产厂家，有近十年的起步阶段，这个阶段发展速度缓慢。再到开创时期，技术水平的不断提高，开始出现专业生产厂家，各种系统开始完善起来，国内的智能化产品开始陆续出现。直到2006年4月当时国家主席胡锦涛同志访问美国，期间参观了微软CEO比尔盖茨的私人别墅，此次访问可以说有力的推动了智能家居在我国的发展。近几年来，智能家居在我国越来越受到企业的关注。现阶段，国内许多国产科技品牌诸如海尔、小米、TCL、海信等也开始进驻智能化家居市场^【2】。然而现阶段各个厂家开发的系统都不相同，各有自己单独的特点，造成了各个系统无法兼容，在实际操作过程中往往会出现各种问题，同时容错率不高导致系统不稳定，难以实现应有的功能，远远无法满足人们对家居智能化的要求^【3】。所以虽然我国在智能家居方面的投资越来越多，但是产品的质量并没有想象的那么好，因此我国的智能家居产业还有很大的提升空间^【4】。同时智能家居在我国发展比较特殊，相关的标准不够完备，国家有关部门也打算制定一套有关家居控制行业的技术标准，来使智能家居行业更好的发展。

• 1. 国外现状

20世纪80年代初，市面上家用电器开始大量采用电子技术，开始出现了住宅电子化的概念；80年代中期，开始有了家居自动化的概念，它就将家中使用的电器、通讯设施与安全防护设施相互独立的设备融合到一起。美国联合科技公司在哈特佛市建造了City Place Building是很著名的一项工程，它真正将智能家居全面的呈现在大众面前，开创了智能化建筑的新纪元，并且在此之后智能型建筑开始在全球范围内风靡起来。其中发展比较迅速的有美国、日本、德国等。由于国外居住特点不像国内，其居住的比较分散，所以智能家居系统各不相同有自己的特点。欧美的智能家居产品以家庭系统为目标设计^【4】，集中控制完备成熟。日本的智能家居发展很快，不但可以将家庭中使用的电器连入互联网，而且可以通过生物认证技术来实现智能家居的安防。例如最近所制造的“保全住宅”，就是使用了这一家居安防系统，同时还设计了防盗室，这个防盗室非常隐蔽。当有小偷闯入住宅时，用户可以躲进防盗室以保证安全。这个防盗室设计内外有两道的坚固的门，其中里面的门只要从里面锁上后，外面依靠小偷的力量是无法打开的，室内装有电话专线，可以随时给用户报警求助使用。韩国数字家庭系统设计有4个标准，需要要让用户在任意时间、地方操控家里的任意电器并能获得各种服务。国外的行业总体发展相比于国内更加成熟，有着比较完备的售前和售后服务，已经从线上销售成功进入线下超市商店的销售^【5】。
