【摘要】：水環(huán)境質(zhì)量監(jiān)測(cè)是我國(guó)環(huán)境保護(hù)工作的重要組成部分,實(shí)施水環(huán)境質(zhì)量監(jiān)測(cè)可以及時(shí)掌握監(jiān)測(cè)地區(qū)的水質(zhì)狀況,保障水資源安全。目前我國(guó)在水環(huán)境監(jiān)測(cè)中主要采用了實(shí)驗(yàn)室手工監(jiān)測(cè)為主自動(dòng)化監(jiān)測(cè)為輔的監(jiān)測(cè)方法,其中水質(zhì)實(shí)驗(yàn)室監(jiān)測(cè)實(shí)時(shí)性較差、人力消耗較大、自動(dòng)化程度較低；水質(zhì)自動(dòng)監(jiān)測(cè)方面在我國(guó)開(kāi)始研究的時(shí)間相對(duì)較晚,這些技術(shù)還處于剛起步階段,與歐洲、北美等發(fā)達(dá)地區(qū)還有著較大的差距。當(dāng)前我國(guó)水質(zhì)自動(dòng)監(jiān)測(cè)工作主要面臨著水質(zhì)監(jiān)測(cè)點(diǎn)地理位置分散,高級(jí)水質(zhì)監(jiān)測(cè)設(shè)備主要靠進(jìn)口、成本相對(duì)較高,國(guó)產(chǎn)有線水質(zhì)監(jiān)測(cè)設(shè)備安裝維護(hù)困難、信息傳輸速率低等問(wèn)題。本文針對(duì)以上問(wèn)題,本文從水質(zhì)遠(yuǎn)程智能化監(jiān)測(cè)系統(tǒng)結(jié)構(gòu)設(shè)計(jì)入手,結(jié)合物聯(lián)網(wǎng)技術(shù)、嵌入式系統(tǒng)技術(shù)、CDMA2000-EVDO通信技術(shù)與傳感器融合技術(shù),設(shè)計(jì)了一種遠(yuǎn)程實(shí)時(shí)的智能化水質(zhì)監(jiān)測(cè)系統(tǒng)。本文所做主要工作如下：1.分析了國(guó)內(nèi)外地區(qū)水質(zhì)監(jiān)測(cè)方面的發(fā)展現(xiàn)狀,結(jié)合實(shí)際需求對(duì)水質(zhì)遠(yuǎn)程監(jiān)測(cè)系統(tǒng)的整體結(jié)構(gòu)進(jìn)行了研究,給出了一種基于CDMA2000的水質(zhì)遠(yuǎn)程智能化監(jiān)測(cè)系統(tǒng)設(shè)計(jì)方案。2.完成了水質(zhì)遠(yuǎn)程監(jiān)測(cè)系統(tǒng)樣機(jī)的硬件設(shè)計(jì)與制作,并且為了便于調(diào)試針對(duì)STM32微處理器、MC509 CDMA2000數(shù)據(jù)終端及SD卡部分繪制了PCB、制作了單獨(dú)的模塊。3.完成了水質(zhì)遠(yuǎn)程監(jiān)測(cè)系統(tǒng)下位機(jī)嵌入式程序的設(shè)計(jì)與編寫(xiě),在STM32微處理器上實(shí)現(xiàn)了μC/OS-Ⅱ嵌入式系統(tǒng)與FatFs文件系統(tǒng)模塊的移植,實(shí)現(xiàn)了穩(wěn)定、高速地采集水質(zhì)傳感器數(shù)據(jù)的功能,并設(shè)計(jì)了MC509數(shù)據(jù)終端在STM32微處理器下的網(wǎng)絡(luò)通信驅(qū)動(dòng)程序,使系統(tǒng)能夠通過(guò)3G移動(dòng)通信網(wǎng)絡(luò)向YeeLink物聯(lián)網(wǎng)云服務(wù)平臺(tái)發(fā)送數(shù)據(jù)。4.完成了水質(zhì)遠(yuǎn)程監(jiān)測(cè)系統(tǒng)的上位機(jī)軟件的設(shè)計(jì)與編寫(xiě),實(shí)現(xiàn)了水質(zhì)數(shù)據(jù)的實(shí)時(shí)獲取、動(dòng)態(tài)圖形界面顯示與超標(biāo)報(bào)警功能。5.針對(duì)pH傳感器的特點(diǎn),研究了傳感器數(shù)據(jù)修正方法,給出了一種采用曲面擬合的溫度補(bǔ)償方法,減小了溫度對(duì)pH值測(cè)量精度的影響。上述工作的完成,很好的解決了運(yùn)用物聯(lián)網(wǎng)與3G技術(shù)來(lái)對(duì)水質(zhì)進(jìn)行實(shí)時(shí)在線監(jiān)測(cè)的技術(shù)難題,達(dá)到了本系統(tǒng)的設(shè)計(jì)目的。通過(guò)對(duì)實(shí)驗(yàn)結(jié)果的分析,本系統(tǒng)監(jiān)測(cè)到的水質(zhì)信息實(shí)時(shí)性好、自動(dòng)化程度高,對(duì)于水質(zhì)監(jiān)測(cè)監(jiān)測(cè)有著重要的實(shí)際參考價(jià)值,同時(shí)對(duì)于其他環(huán)境監(jiān)測(cè)也具有重要的借鑒意義。
[Abstract]:The monitoring of water environment quality is an important part of environmental protection work in China. The implementation of water environment quality monitoring can grasp the water quality situation of monitoring areas in time and ensure the safety of water resources.At present, the monitoring method of laboratory manual monitoring is mainly used in water environment monitoring in China, in which the real-time performance of water quality laboratory monitoring is poor, the manpower consumption is large, and the degree of automation is low.The research on automatic monitoring of water quality is relatively late in China. These technologies are still in their infancy and still have a big gap with developed regions such as Europe and North America.At present, the automatic water quality monitoring work in China is mainly faced with the geographical dispersion of water quality monitoring points, the import of advanced water quality monitoring equipment, the relatively high cost, and the difficulty of installation and maintenance of domestic wired water quality monitoring equipment.Information transmission rate is low and so on.In view of the above problems, this paper starts with the structure design of water quality remote intelligent monitoring system, combining with the technology of Internet of things, embedded system technology, CDMA2000-EVDO communication technology and sensor fusion technology,A remote and real-time intelligent water quality monitoring system is designed.The main work of this paper is as follows: 1.The development status of water quality monitoring in domestic and foreign areas is analyzed. The overall structure of water quality remote monitoring system is studied in combination with actual demand. A design scheme of remote intelligent water quality monitoring system based on CDMA2000 is presented.The hardware design and manufacture of the water quality remote monitoring system prototype are completed. In order to debug the STM32 microprocessor MC509 CDMA2000 data terminal and SD card, a separate module .3is made.The embedded program of the water quality remote monitoring system is designed and written.
