智能家居防盗系统

摘要:本系统以单片机AT89S52为控制核心,采用采用音频解码芯片HT9200A和高保真语音录放集成芯片ISD4004,利用个人通信终端(电话、手机等)实现对电器设备的远程控制。配合多路红外遥控技术,实现对电器设备的近距离遥控,并辅助使用单总线数字温度传感器DS18B20及高精度时钟日历芯片PCF8563显示时钟日历及温度。该系统由单片机构成主控部分,进行主要的信息处理,接收外部操作指令形成各种控制信号。在远程控制方面,使用不同的语音提示实现对不同电器的操作和对受控电器状态的反馈,从而使操作者能够及时了解被控电器的信息,使产品达到交互式与智能化,由电话机组成的自动拨号报警功能,使得本系统的功能大大地增强,使居家生活更加趋于智能化。将该系统与PC机相连,可直接由PC机控制家电,也可用遥控器控制PC机,该系统具有控制灵活、可操作性强、可扩展性强、发展潜力大等优点,是实现智能化家居、智能化寓所的智能电器控制系统,具有十分广阔的市场前景和非常良好的应用价值。

Abstract:The system uses the AT89S52 MCU as its control center, adopts the double-tone multiple frequency code-interpret IC MT8870 and athering chip ISD4003-6M,make use of individual correspondence term- inal (telephone、mobile phone etc.)to realize long-distance control of the electronic equipment. Match with the infrared ray long-distance technology, it realizes near-distance control and uses the single-total line digital temperature Spread the feeling machine DS18B20 and high accuracy clock calendar chip PCF8560 to manifest the clock 、the calendar and the temperate. The main control part of this system is made up with the MCU, it does the main massage handles, receives exterior operation instruction and forms various control signal. In the aspects of long-distance controlling , using different voice to hint different operation and give a state feedback of the be-controlled ,thus it can let the writer know the information of the be-controlled, let the production to be change over with each other type and intellectualized。The auto dialing alarming function made up with the phone improves the usage of this system highly, makes the family life more intellectu- alized.Connecting this system with the PC and using the appliated program, it can control the household appliance by the PC machine directly. The PC machine can be hand-controlled and also can be controlled by the infrared ray remote control. It has many superiority on it. For example, agile controllment, powerful maneuverability and expansibility, and great potentiality .There are expansive foreground and very good application worth on this PLC wirings intellectualized managed system.
