智能家居環境監測系統
近些年來,智能家居系統的使用功能愈加健全。本文之中在充分了解嵌入式系統平臺的具體構建的前提下,以智能家居系統當前的功能要求為主要方向,以該平臺的硬件設計為切入點,細致探索了嵌入式平臺的通訊以及硬件情況,并開發了以GPRS為依托的智能家居系統。該系統實際告有兩大部分,一是遠程控制模塊;二是家居安防模塊。
其中,家庭安防模塊不但要兼顧家庭里、外的整個安全防范,而且還對家庭環境信息的監控(如煤氣泄露等)有極大的用途。若是出現了險情,則實施以下相關操作:打開報警器開關,然后經GPRS模塊向室內人員及相關部門給出報警提醒,以消除險情。若出現了火情信息,還會開啟噴水設施。
經遠程的調控,給使用者創設了極為便利的家居環境。使用者借助GPRS能傳出控制指令,從而對空調等各類家用設備實施開關上的調控。家庭設備控制模塊能夠分析家用設備的具體情況,以選擇適合的生活環境。
課題設計包括硬件設計和軟設計兩部分。硬件部分包括硬件的選型、連接、調試。在開發板現有的外圍模塊上設計了GPRS通信模塊315MRF 數據接收模塊。軟件的實現是在硬件調試通過的基礎上進行編程,先在PC機Linux 系統下編程,然后,就開始軟件上的設計通過Linux系統實實再將編程的內窨傳至開發根上。并且給出了開發平臺,不但完成了本文系統的嵌入式Linux2.6.14內核的移植、以及引導程序ViVi的移植,而且還完成了NFS根文件系統的有效移植。在應用程序方面主要是以多線程的編程為主如此一來。就有利于對以上兩個添加的模塊之間實施有效的訪問控制。此外,給出了更適合的硬件驅動程序,以便對全部的報警信號均能實施有效的調控。最終,本文從硬件乃至軟件上真正的做到了對智能家居系統的開發。

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
