智能家居环境监测系统

近些年来，智能家居系统的使用功能愈加健全。本文之中在充分了解嵌入式系统平台的具体构建的前提下，以智能家居系统当前的功能要求为主要方向，以该平台的硬件设计为切入点，细致探索了嵌入式平台的通讯以及硬件情况，并开发了以GPRS为依托的智能家居系统。该系统实际告有两大部分，一是远程控制模块；二是家居安防模块。

其中，家庭安防模块不但要兼顾家庭里、外的整个安全防范，而且还对家庭环境信息的监控(如煤气泄露等)有极大的用途。若是出现了险情，则实施以下相关操作：打开报警器开关，然后经GPRS模块向室内人员及相关部门给出报警提醒，以消除险情。若出现了火情信息，还会开启喷水设施。

经远程的调控，给使用者创设了极为便利的家居环境。使用者借助GPRS能传出控制指令，从而对空调等各类家用设备实施开关上的调控。家庭设备控制模块能够分析家用设备的具体情况，以选择适合的生活环境。

课题设计包括硬件设计和软设计两部分。硬件部分包括硬件的选型、连接、调试。在开发板现有的外围模块上设计了GPRS通信模块315MRF 数据接收模块。软件的实现是在硬件调试通过的基础上进行编程,先在PC机Linux 系统下编程，然后，就开始软件上的设计通过Linux系统实实再将编程的内窨传至开发根上。并且给出了开发平台，不但完成了本文系统的嵌入式Linux2.6.14内核的移植、以及引导程序ViVi的移植，而且还完成了NFS根文件系统的有效移植。在应用程序方面主要是以多线程的编程为主如此一来。就有利于对以上两个添加的模块之间实施有效的访问控制。此外，给出了更适合的硬件驱动程序，以便对全部的报警信号均能实施有效的调控。最终，本文从硬件乃至软件上真正的做到了对智能家居系统的开发。

Abstract

After several years of development, the performance of the smart home system has become more and more mature and perfect. This paper base on building the platform of embedded computer system, aim at feed function acquirement and development of smart home system, starting from the hardware of embedded computer system and researching its communication system and its hardware system，and design the smart home system based on GPRS. From classification division of the sub system, which is composed by home security systems and remote-control systems.

The home security is a system what the home internal security combines with the external security, and carries on the real-time monitoring to the home environment signal, such as fire, that, combustible gas disclosure.

Once there is a dangerous occurrence, it will perform specific operation such as tum on alarm switch in the case of a fire signal it will turn on the water-tap which used for Fire extinguishing installations. Besides, it will send an alarm message to the householder and the Property Management Center via the GPRS to inform the dangerous, so that the danger obtains the effective control.

Remote control provides a comfortable and convenient living environment to the use
