1、摘要 随着经济的不断发展，科技的不断进步，人们的生活也在不断发生变化，家电作为人类生活的必需品之一，也将开始书写它的新篇章。当前，家电行业的不断发展，使得人们对家电的认知也从追求耐用发展到追求舒适化、健康化、个性化、智能化、信息化以及人性化。然而，分析家电市场的现状，我们可以知道一体化、智能化、便捷化、网络化等是家电当前及长时间内的一种新的发展趋势。手机发送短信指令部分。手机的普及率很高，而且无线网络覆盖范围广，在信息传递方面性能稳定、可靠，所以用手机作为信息传递的载体，方便、可靠、成本低，特别是在远程数据传输。所以本设计综合运用物联网，采用手机短信的形式通过 GSM网络来无线控制家电。单片机
2、处理短信指令部分。在这个部分，首先，我们要用 ATE 指令确认单片机是否与简易通讯设备连接起来。其次，用 AT+CMGF 指令选定短消息的数据格式。最后，在收到手机的正确回答反以 AT 指令完成读出功能。一般用 AT+CMGL 读取以前的信息，在收到手机的短信数据时，用 AT+CMGR 读取实时信息。家用电器通过单片机进行反馈部分。此部分是连接到基于 GTM900C 模块电路进行反馈指令，使得家用电器在智能的同时更加的人性化。此部分也是通过单片机来完成的，将反馈指令编码为手机通讯语言，反馈给简单通讯设备，再由简单通讯设备发送反馈短信给用户。关键词关键词 GTM900C；远程家电控制；GSM；智
