智能家居環(huán)境監(jiān)測(cè)系統(tǒng)
近些年來(lái),智能家居系統(tǒng)的使用功能愈加健全。本文之中在充分了解嵌入式系統(tǒng)平臺(tái)的具體構(gòu)建的前提下,以智能家居系統(tǒng)當(dāng)前的功能要求為主要方向,以該平臺(tái)的硬件設(shè)計(jì)為切入點(diǎn),細(xì)致探索了嵌入式平臺(tái)的通訊以及硬件情況,并開發(fā)了以GPRS為依托的智能家居系統(tǒng)。該系統(tǒng)實(shí)際告有兩大部分,一是遠(yuǎn)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(gè)安全防范,而且還對(duì)家庭環(huán)境信息的監(jiān)控(如煤氣泄露等)有極大的用途。若是出現(xiàn)了險(xiǎn)情,則實(shí)施以下相關(guān)操作:打開報(bào)警器開關(guān),然后經(jīng)GPRS模塊向室內(nèi)人員及相關(guān)部門給出報(bào)警提醒,以消除險(xiǎn)情。若出現(xiàn)了火情信息,還會(huì)開啟噴水設(shè)施。
經(jīng)遠(yuǎn)程的調(diào)控,給使用者創(chuàng)設(shè)了極為便利的家居環(huán)境。使用者借助GPRS能傳出控制指令,從而對(duì)空調(diào)等各類家用設(shè)備實(shí)施開關(guān)上的調(diào)控。家庭設(shè)備控制模塊能夠分析家用設(shè)備的具體情況,以選擇適合的生活環(huán)境。
課題設(shè)計(jì)包括硬件設(shè)計(jì)和軟設(shè)計(jì)兩部分。硬件部分包括硬件的選型、連接、調(diào)試。在開發(fā)板現(xiàn)有的外圍模塊上設(shè)計(jì)了GPRS通信模塊315MRF 數(shù)據(jù)接收模塊。軟件的實(shí)現(xiàn)是在硬件調(diào)試通過的基礎(chǔ)上進(jìn)行編程,先在PC機(jī)Linux 系統(tǒng)下編程,然后,就開始軟件上的設(shè)計(jì)通過Linux系統(tǒng)實(shí)實(shí)再將編程的內(nèi)窨傳至開發(fā)根上。并且給出了開發(fā)平臺(tái),不但完成了本文系統(tǒng)的嵌入式Linux2.6.14內(nèi)核的移植、以及引導(dǎo)程序ViVi的移植,而且還完成了NFS根文件系統(tǒng)的有效移植。在應(yīng)用程序方面主要是以多線程的編程為主如此一來(lái)。就有利于對(duì)以上兩個(gè)添加的模塊之間實(shí)施有效的訪問控制。此外,給出了更適合的硬件驅(qū)動(dòng)程序,以便對(duì)全部的報(bào)警信號(hào)均能實(shí)施有效的調(diào)控。最終,本文從硬件乃至軟件上真正的做到了對(duì)智能家居系統(tǒng)的開發(fā)。

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
