【摘要】：隨著社會的發(fā)展,人口集聚膨脹導(dǎo)致環(huán)境問題日益嚴(yán)重,生存環(huán)境惡化已經(jīng)嚴(yán)重影響到人類的生產(chǎn)生活。環(huán)境問題已成為社會熱門話題,對于環(huán)境的治理刻不容緩,而水污染問題尤為突出。對于水體污染問題的治理,首先要對水體污染物進(jìn)行檢測,而先進(jìn)的水污染檢測系統(tǒng)將有助于問題的解決。水污染的檢測包含眾多檢測參數(shù),主要有化學(xué)需氧量(COD)、重金屬元素、PH值、溫度等。當(dāng)前國內(nèi)外的許多水污染物檢測設(shè)備的精度不高、檢測物質(zhì)單一、檢測方法繁雜、無法通過網(wǎng)絡(luò)進(jìn)行在線監(jiān)測。本課題將著重研究水污染檢測系統(tǒng),對于存在的問題做了很大的改善。它將采用基于ARM內(nèi)核的處理器,以及設(shè)計了一系列的外圍電路搭建整個檢測系統(tǒng)的硬件電路框架,包括電源、存儲芯片、LCD、網(wǎng)卡芯片以及信號處理電路等,同時系統(tǒng)還設(shè)計了JTAG接口用于系統(tǒng)的調(diào)試,方便系統(tǒng)的開發(fā)。整個系統(tǒng)將采用嵌入式Linux操作系統(tǒng)實(shí)現(xiàn)檢測系統(tǒng)實(shí)現(xiàn)了多任務(wù)、智能化、網(wǎng)絡(luò)化的要求。該系統(tǒng)采用三星的S3C2440為主控芯片,通過TI公司的ADS8371芯片轉(zhuǎn)換各類水污染檢測傳感器采集到的數(shù)據(jù),通過網(wǎng)卡芯片與上位機(jī)相連,實(shí)現(xiàn)了在線檢測和數(shù)據(jù)存儲,還可以將采集到的數(shù)據(jù)存儲于系統(tǒng)自帶的存儲芯片中,在沒有上位機(jī)工作的情況下系統(tǒng)正常實(shí)現(xiàn)檢測任務(wù)。嵌入式系統(tǒng)軟件設(shè)計詳細(xì)分析了Bootloader、Linux的裁剪移植和根文件系統(tǒng)的制作,是整個系統(tǒng)的正常運(yùn)行必不可少的部分,檢測系統(tǒng)還要實(shí)現(xiàn)必要的應(yīng)用程序,以滿足不同的需求。整個系統(tǒng)的開發(fā)完成以后,通過實(shí)驗(yàn)來完成對水體污染物檢測。以化學(xué)需氧量和重金屬為例,將作為檢測對象,通過實(shí)際的檢測來模擬系統(tǒng)的一般工作狀況,輔以數(shù)學(xué)方法計算出檢測結(jié)果,在與檢測的結(jié)果相比較驗(yàn)證系統(tǒng)的可行性。
[Abstract]:With the development of society, the agglomeration of population leads to increasingly serious environmental problems, and the deterioration of the living environment has seriously affected the production and life of human beings. Environmental problem has become a hot topic in the society. It is urgent to control the environment, and the water pollution problem is especially prominent. For the treatment of water pollution, the first step is to detect the water pollution, and the advanced water pollution detection system will be helpful to solve the problem. The detection of water pollution includes many parameters, such as chemical oxygen demand (COD), heavy metal pH, temperature and so on. At present, many water pollutant detection equipments at home and abroad have low precision, single detection material and complicated detection methods, which can not be monitored online through network. This subject will focus on the study of water pollution detection system, the existing problems have been greatly improved. It will adopt the processor based on ARM kernel, and design a series of peripheral circuits to build the hardware circuit frame of the whole detection system, including power supply, memory chip LCD, network card chip and signal processing circuit, etc. At the same time, the JTAG interface is designed to debug the system, which is convenient for the development of the system. The whole system adopts the embedded Linux operating system to realize the multi-task, intelligent and network requirement. The system uses S3C2440 of Samsung as the main control chip, converts the data collected by various water pollution detection sensors through the ADS8371 chip of TI Company, and connects with the host computer through the network card chip, realizes on-line detection and data storage. The collected data can also be stored in the system's own memory chip, and the system can normally realize the detection task without the upper computer working. The software design of embedded system analyzes in detail the cutting and transplanting of Bootloadern Linux and the making of root file system, which is an essential part of the normal operation of the whole system. The detection system also needs to realize the necessary application program to meet different requirements. After the development of the whole system, the detection of water pollutants is completed through experiments. Taking chemical oxygen demand (COD) and heavy metal as examples, this paper simulates the general working condition of the system through actual detection, and calculates the test result by mathematical method, and verifies the feasibility of the system compared with the test result.
