1、摘 要随着计算机技术和通信技术的飞速发展，人类的生活水平有着日新月异的变化， “以人为本、舒适、便利、智能化”已成为家居系统的重要设计理念，家居智能化控制系统力求创造安全、舒适的生活环境的设计理念，成为当今众多开发商高度关注的卖点之一。为此本设计研制了智能家居控制系统的控制主机。本设计根据设计任务和实际考察进行了方案设计和方案论证，并且设计了相应的硬件电路和软件系统，研制了智能家居控制系统的控制样机。该系统由远程控制和报警系统两大部分组成，控制部分以电话交换网的ITU及国家标准程控交换信令作为系统控制命令，给身份识别和控制单元提供控制信号；报警部分巡回检测门窗磁传感器信号、可燃气体泄漏传感器信
2、号以及有人出入房间信号等，对信号进行分析，根据用户设定情况通过GSM短消息平台向用户发出报警信息或进行现场防盗报警等。本系统采用的主控芯片是SM8952AC25P单片机，采用基于国际双音频通信标准DTMF通信方式的MT8870完成部分程控交换信， GSM模块采用TC35短消息模块，设计的过程充分利用了各个模块与单片机的标准接口，根据单片机良好的控制性能完成了报警信号采集和分析、键盘输入、各模块控制和通信、数据显示、强电控制信号处理、与PC机通信以及对红外学习遥控等功能。对系统样机的实际调试和使用结果表明，完成了设计实现了设计任务规定的基本功能。此外，实现了与PC机联机使用，满足控制空调等红外遥
3、控设备的需求，实现了学习型远程红外遥控功能，这部分超出了设计任务书规定的任务。关键词：DTMF；远程控制；单片机；GSM；红外遥控AbstractWith the development rapidly of computer technology and communicable technology, human standard of living change largely. And the idea of based on human, coziness, convenience and intelligentize is already become important desi
4、gn ideas, meanwhile, the design idea of aiming at establish safe and comfortable living environment is also becoming the selling merit that lots of land agents have more attention. In this paper, intelligent house control system has been researched and produced.Design scheme and demonstrated scheme
5、are carried out based on the design task and observation in reality, hardware and software system is all designed, and the demonstrated product of intelligent control system is produced.This system is composed of two parts, first part is control module, which use the code of ITU of telephone exchang
6、e net and standard remote control exchange signal as control code and also control the modules of identification and control modules, the second part is warning part, which detect the signal from the magnetic sensor fixing at door and window in cycles and the signal from the sensor of gas leaking an
7、d so on, after analyzing the signals, warning message and guard against theft message is transfer by GSM based on the pre-setting from user.SM8952AC25P is the core of this system, combining with MT8870 for partly remote control signal exchange based on international communication standard DTMF, TC35
8、 is used in the GSM module, the standard interface of MCU is all made use of for connecting the sub-modules. The warning signal collection and analysis, keyboard input acquirement, communication among all modules, data display, power control signal process and so on. The test for demonstrated produc
9、t illustrated that the basic function regulated in design task for graduation is completely finished, in addition, some innovation in this system is achieved for cooperating with pc, this system have the learning remote control infrared function that meet the requirement of control air-condition with infrared signal, which beyond the prescript of design task.Key words： DTME remote control MCU GSM infrared control
