摘要
 随着我的提高,手机已经在家庭普及, 利用手机实现家用电器遥控是家电未来的发展方向。这样设计将人们的生活带来很多的便利,简单的例子,炎炎的夏日,主人可以在下班前半小时遥控打开空调,下班进家就有一种很凉爽的感觉;可以遥控开启微波炉、电饭锅等炊具,一回到家便可享受美味的饭菜。在高科技给人们带来便利的同时,家庭安全防护意识也越来越受到人们的重视,如果家中有警情(如火警、盗警等)时,主人还希望能及时获知警情,采取及时有效的措施。本系统设计实用,功能灵活多样,可靠性高,操作方便,可以广泛地应用于家庭或者其它场所的智能控制。电话远程控制不需进行专门的布线,可避免电磁污染,是符合社会发展和时代要求的一项自动控制技术。

Abstract
With the development of our national economy, improvement of people's living standard.  Along with the widespread use of telephone in family, the remote control of household appliances by means of telephone is to be realized in the future. This design will bring a lot of people's life convenient, for example, , the heat of summer, the owner can work the remote control to open half an hour before air-conditioning, work into the home have a very cool feeling; can remotely open the microwave oven, rice cooker and other cooking utensils, a home can enjoy delicious meals. In the high-tech convenience to the people at the same time, the family has e increasingly security conscious attention, if the police family situation (such as fire, theft alarm, etc.), the owner also informed the police hope that in time the situation and take timely effective measures. This system design and practical function, flexible, convenient operation, high reliability, and can be widely applied in the family or other places of intelligent control. Phone remote control to special cabling, can avoid ic pollution, conforms to the social development and the demands of the era of an automatic control technology.
