基于GPRS的远程智能家电控制系统设计
摘要
随着网络技术和通信技术的不断发展以及人们对生活要求的不断提高,实现家庭智能的远程控制已经成为必然的趋势。本文采用嵌入式系统和GPRS通讯技术相结合的方式,搭建了一个家庭智能管理平台。通过该平台,网络等方式,实现对家庭系统的远程监控。
本文设计了一个基于单片机的智能家电控制系统。系统模块主要包括GPRS无线通讯模块、家庭智能控制器模块。其中家庭智能控制器是系统的核心,主要完成了对家庭系统的智能管理以及和GPRS无线模块的通讯。本设计以实现家用电器的开关为例。
硬件方面以AT89C51单片机为核心,采用了HK21F继电器控制家用电器的通断,以周立功公司ZWG-23A型号的GPRS无线通信模块为基础,基于AT指令和数据采集器,构建一个远程的智能家电控制系统,对家电进行控制,本设计以控制灯泡为例,实现了对灯泡的开关控制和状态反馈。软件方面,主要实现对用户短信的分析识别处理,根据处理好的数据对继电器进行控制,以达到控制灯泡的目的,通过光电开关对灯泡的当前状态进行检测并把数据送给AT89C51单片机,AT89C51单片机再通过GPRS模块以短信的方式把具体信息反馈给用户。
实践结果表明,该系统使用效果良好,应用前景广泛。

Based on GPRS wireless home the overall intelligent control system solutions
Abstract:As the continuous development work munication technology as well as the improvement of people’s living standard, the realization of remote control of Home Intelligence has e an inevitable trend. In this paper, a Home Intelligent management platform, bines home applications, burglary protection system and hydroelectric anicly, is established by using embedded bined with GPRS technology and RS485 bus technique to realize intelligent management of home applications and other home systems. Based on the platform, SMS and can be used to realize remote control of the home system.
In the thesis design a based on SCM intelligent appliances control system. System module mainly including GPRS munication module, family intelligent controller module. One family intelligent controller is the core of the system, the pletion of the family system of intelligent management and GPRS wireless munications. The family system module mainly realizes the family system in the monly used the switch quantity control etc. Function.
Hardware with AT89C51, using a HK21F relay control household appliances hige to GPRS munication module as the foundation, based on instructions and data terminal tractor, build a remote intelligent appliances control system, control of home appliance. Software for the
