基于图像的企业环境监测系统设计（本科毕业论文设计）.doc

摘 要
本次设计是设计一个基于图像的环境监测系统，以攀钢的景观在线监测系统为例，主要讨论系统的结构设计和硬件的选型。
数字化环境监测系统取代了传统的传感器监测，它通过拍摄图像，并运用计算机对图像进行计算分析，该系统充分利用网络资源，实现了环境监测的网络化管理，节约了成本。在本次设计过程中，先收集资料，对环境监测系统有一个感性的认识，并研究其发展的现状；再通过对攀钢的考察进一步明确系统结构，分析系统结构并画出拓扑图；再对其中的关键技术进行研究：如H264图像压缩算法、VLAN技术、硬盘录像机（DVR)研究选型等；最后通过实验对系统运行状况进行深刻了解。

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)
