【摘要】：隨著水質污染越來越加劇,全球水質系統(tǒng)日益惡化,已經(jīng)嚴重影響人類社會和經(jīng)濟的發(fā)展。以往大部分水質評估方式通過定期取樣來了解水質變化,對于突然之水質變化,如污水排放等影響水質事件無法立即感知,因此建立實時水質監(jiān)測系統(tǒng)尤其必要性。目前在線視頻監(jiān)測系統(tǒng)已經(jīng)較為普及,但視頻監(jiān)控技術大量運用在社會公共安全領域,且以有線傳輸為主。本文通過基于4G和GPON組合技術的研究,設計出用手機終端在線實時查看水質透明度和色度的視頻監(jiān)控方案。首先,本文系統(tǒng)闡述了水質監(jiān)測技術的背景及研究的重要性,給出了研究的目的和意義,并指出本文研究的主要內容和創(chuàng)新點;介紹4G和GPON接入概念、原理、組網(wǎng)等相關技術,特別是4G技術的網(wǎng)絡優(yōu)化方案及目前取得的階段性成果。其次,分析移動視頻監(jiān)控在公安部門治安動態(tài)監(jiān)控項目上的應用,強調GPON技術在接入層網(wǎng)絡上達到了較為理想的效果。為本文后續(xù)水污染監(jiān)控系統(tǒng)設計提供了案例基礎。接著,分析水質視頻監(jiān)控系統(tǒng)需要的硬件條件和實驗平臺,并引入水質視頻監(jiān)控系統(tǒng)的總體設計,尤其是GPON接入系統(tǒng)劃分的模塊以及本系統(tǒng)點位分布。通過在手機終端下載和使用"和慧眼'"軟件,實現(xiàn)在線水質監(jiān)控。最后通過實驗分析得出水質透明度和色度兩個參數(shù)同點位不同時間段差異變化,起到實時監(jiān)控水質的目的。由于研究時間和條件所限,本文對于水質視頻監(jiān)控系統(tǒng)還存在許多值得改進的地方和拓展的空間,希望后續(xù)能將水質傳感器采集的定量數(shù)據(jù)通過視頻回傳至手機終端,起到更好的監(jiān)控作用。
[Abstract]:With the worsening of water pollution and the worsening of global water quality system, the development of human society and economy has been seriously affected. In the past, most water quality assessment methods used to understand the changes of water quality through regular sampling, and could not immediately perceive the sudden changes of water quality, such as sewage discharge and other events affecting water quality, so it is particularly necessary to establish a real-time water quality monitoring system. At present, the online video monitoring system has been popularized, but video surveillance technology is widely used in the field of social public security, and cable transmission is the main technology. Based on the research of combination technology of 4G and GPON, this paper designs a video monitoring scheme of real-time viewing water quality transparency and chromaticity with mobile phone terminal. Firstly, the background and importance of water quality monitoring technology are systematically expounded, the purpose and significance of the research are given, and the main contents and innovations of this paper are pointed out, and the concept, principle, networking and other related technologies of 4G and GPON access are introduced. Especially, the network optimization scheme of 4G technology and the achievements made at present. Secondly, the application of mobile video surveillance in the public security dynamic monitoring project is analyzed, and the GPON technology is emphasized to achieve a better effect on the access layer network. It provides a case basis for the design of water pollution monitoring system in this paper. Then, the hardware condition and experimental platform of water quality video monitoring system are analyzed, and the overall design of water quality video monitoring system is introduced, especially the module of GPON access system and the point distribution of the system. Through downloading and using the "and eye 'software in the mobile terminal, water quality monitoring is realized online." Finally, through the experimental analysis, it is concluded that the two parameters of water quality transparency and chromaticity are different in different time periods at the same point, which plays the purpose of monitoring water quality in real time. Due to the limitation of research time and conditions, there are still many improvements and space for water quality video monitoring system in this paper. It is hoped that the quantitative data collected by water quality sensors can be transmitted back to the mobile terminal through video. Play a better monitoring role.
