【摘要】：随着现代人生活水平的改善，智能化生活方式成为现代人关注的热点，家居智能化成为了一种必然的趋势。针对传统智能家居需要重新布线、家居设备布局分散、无法智能协调工作、不能集中控制等缺点，本文设计了一种基于ARM嵌入式平台的智能家居监控系统。本文在分析嵌入式技术、低压电力线组网技术和GPRS无线技术等关键技术的基础上，确定了嵌入式智能家居监控系统的解决方案。系统采用S3C2440A作为中心控制单元，设计了S3C2440A的外围电路，移植了Linux操作系统并编写相应的控制代码，实现了中心控制单元与各个子模块和移动终端的数据传输，提高了系统的性能；采用低压电力线载波通信组网技术，组建智能家居网络，免去重新布线的困扰；设计了智能灯光模块、智能窗户模块、家居安防模块的硬件电路，编写各部分驱动程序和应用程序，实现数据的采集和传输；设计了家居安防报警电路，当家居环境异常时会自动启动报警装置，并向用户手机发送警报短信，确保家居环境的安全；分析了地址分配机制和帧命令的组成机制，，采用了通用的645协议，在Android平台上进行控制界面的开发，实现了家居设备的远程监控。通过GPRS模块，用户可以利用手机、IPAD或电脑等移动终端来访问或控制家居设备的状态。本文实现了情景灯、智能窗和家居安防模块的状态控制和上报，并具有防火、防盗、防煤气泄漏等监测功能。调试和实验结果表明：本系统运行稳定、可靠，达到了预期的设计目标，能够满足人们高水平的生活要求。本文为智能家居监控系统的设计提供了一个合理的解决方案。
[Abstract]:With the improvement of modern people's living standard, intelligent life style has become the focus of modern people's attention, and home intellectualization has become an inevitable trend.Aiming at the shortcomings of traditional smart home, such as rewiring, scattered layout of home equipment, inability to coordinate intelligent work and centralized control, a kind of intelligent home monitoring system based on ARM embedded platform is designed in this paper.Based on the analysis of embedded technology, low-voltage power line networking technology and GPRS wireless technology, this paper determines the solution of embedded intelligent home monitoring system.The system adopts S3C2440A as the central control unit, designs the peripheral circuit of S3C2440A, transplants the Linux operating system and writes the corresponding control code, realizes the data transmission between the central control unit and each sub-module and mobile terminal.It improves the performance of the system, adopts low-voltage power line carrier communication networking technology to build smart home network, avoids the trouble of rewiring, and designs the hardware circuit of intelligent lighting module, intelligent window module and home security module.The driver and application program are written to collect and transmit the data, and the alarm circuit of home security is designed. When the home environment is abnormal, the alarm device will be started automatically, and the alarm text message will be sent to the user's mobile phone.In order to ensure the security of home environment, the composition mechanism of address assignment and frame command is analyzed, and the general 645 protocol is adopted. The control interface is developed on Android platform, and the remote monitoring of home equipment is realized.Through the GPRS module, users can access or control the status of home devices by using mobile terminals such as mobile phones, iPads or computers.This paper realizes the state control and report of scene lamp, intelligent window and home security module, and has the monitoring functions of preventing fire, theft, gas leakage and so on.The results of debugging and experiment show that the system runs stably and reliably, achieves the expected design goal, and can meet people's high standard of life.This paper provides a reasonable solution for the design of intelligent home monitoring system.
