摘 要
本次設(shè)計(jì)是設(shè)計(jì)一個基于圖像的環(huán)境監(jiān)測系統(tǒng)，以攀鋼的景觀在線監(jiān)測系統(tǒng)為例，主要討論系統(tǒng)的結(jié)構(gòu)設(shè)計(jì)和硬件的選型。
數(shù)字化環(huán)境監(jiān)測系統(tǒng)取代了傳統(tǒng)的傳感器監(jiān)測，它通過拍攝圖像，并運(yùn)用計(jì)算機(jī)對圖像進(jìn)行計(jì)算分析，該系統(tǒng)充分利用網(wǎng)絡(luò)資源，實(shí)現(xiàn)了環(huán)境監(jiān)測的網(wǎng)絡(luò)化管理，節(jié)約了成本。在本次設(shè)計(jì)過程中，先收集資料，對環(huán)境監(jiān)測系統(tǒng)有一個感性的認(rèn)識，并研究其發(fā)展的現(xiàn)狀；再通過對攀鋼的考察進(jìn)一步明確系統(tǒng)結(jié)構(gòu)，分析系統(tǒng)結(jié)構(gòu)并畫出拓?fù)鋱D；再對其中的關(guān)鍵技術(shù)進(jìn)行研究：如H264圖像壓縮算法、VLAN技術(shù)、硬盤錄像機(jī)（DVR)研究選型等；最后通過實(shí)驗(yàn)對系統(tǒng)運(yùn)行狀況進(jìn)行深刻了解。


關(guān)鍵詞：數(shù)字化環(huán)境監(jiān)測系統(tǒng)、 H264圖像壓縮算法、 VLAN技術(shù)、
硬盤錄像機(jī)（DVR)

























Abstract

The design is designong a image-based environmental monitoring system.Panzhihua Iron and Steel to the landscape on-line monitoring system as an example,this design focused on the structural design and hardware Selection.
Digital environment monitoring system has replaced the traditional sensor monitoring.
Through the photograph images,It uses a computer for image analysis.The system takes full advantage of network resourc, realizes the environmental monitoring network management,saves cost.In the design process,through collecting information,our environmental monitoring system has a perceptual awareness.Re-inspected by the Panzhihua Iron and Steel further defined the system architecture,Analysis of the structure and system to draw topology;we research key technologies in systems . For example H264 image compression algorithm,VLAN,Hard drive recorders (DVR), and so on Selection.Final adoption of the system is running a deep understanding of the situation.

Keywords: Digital Environment Monitoring System,
H264 image compression algorithm,
VLAN technology, Hard drive recorders (DVR)
