【摘要】：隨著工業(yè)的發(fā)展,其給人們的生活帶來很多便利。然而,工業(yè)生產(chǎn)過程中會(huì)產(chǎn)生很多對(duì)人體有害的因素,比如煤炭開采、水泥生產(chǎn)等行業(yè)中的粉塵污染。其在各種危害因素中對(duì)人體健康的影響最為嚴(yán)重。粉塵對(duì)人體的危害最直接、最嚴(yán)重的是引起塵肺病。當(dāng)粉塵濃度過高時(shí),在高溫干燥的時(shí)候可能產(chǎn)生爆炸。因此,溫度和濕度也是一個(gè)重要的參考因素。 本課題所設(shè)計(jì)的粉塵濃度和溫濕度嵌入式檢測(cè)系統(tǒng)是基于粉塵檢測(cè)技術(shù)、溫濕度檢測(cè)技術(shù)、以太網(wǎng)傳輸技術(shù)、3G無線傳輸技術(shù)等設(shè)計(jì)而成的。以ARM為核心,主要實(shí)現(xiàn)對(duì)傳感器采集到的數(shù)據(jù)處理、顯示、存儲(chǔ)和通信。粉塵傳感器根據(jù)光的反射原理,當(dāng)粉塵顆粒經(jīng)過傳感器內(nèi)部光束的時(shí)候,傳感器通過檢測(cè)反射光的強(qiáng)度而得到相應(yīng)粉塵的濃度。溫濕度傳感器通過把溫度信號(hào)和濕度信號(hào)轉(zhuǎn)換成電信號(hào),經(jīng)過信號(hào)調(diào)理和AD轉(zhuǎn)換,最后得到相應(yīng)的濃度值。ARM根據(jù)傳感器時(shí)序發(fā)送指令得到相應(yīng)濃度值,首先進(jìn)行本地顯示和存儲(chǔ),然后通過以太網(wǎng)或者3G無線模塊把數(shù)據(jù)傳輸給上位機(jī),上位機(jī)得到數(shù)據(jù)后對(duì)數(shù)據(jù)進(jìn)行存儲(chǔ)和分析,如果有數(shù)據(jù)超過范圍或者異常及時(shí)報(bào)警。達(dá)到對(duì)數(shù)據(jù)實(shí)時(shí)監(jiān)測(cè)的目的。 在硬件方面,采用了三星ARM9芯片S3C2440作為處理器,搭配相應(yīng)的外部SDRAM和外部NORFLAS-II以基于光的反射原理的粉塵傳感器GP2Y1010AUOF和溫濕度傳感器SHT11進(jìn)行數(shù)據(jù)的采集。ARM通過采集和計(jì)算得到最終結(jié)果,然后通過以太網(wǎng)和3G模塊傳輸給PC機(jī)進(jìn)行數(shù)據(jù)的存儲(chǔ)和處理。 軟件方面,分為上位機(jī)和下位機(jī)。下位機(jī)主要由u COS-II嵌入式操作系統(tǒng)及在此系統(tǒng)上的各個(gè)任務(wù)模塊組成。下位機(jī)主要實(shí)現(xiàn)驅(qū)動(dòng)各個(gè)傳感器模塊采集數(shù)據(jù),然后通過TCP/IP協(xié)議或者3G模塊把數(shù)據(jù)發(fā)送到上位機(jī)。上位機(jī)基于delphi平臺(tái)進(jìn)行編寫,主要接收下位機(jī)發(fā)送過來的粉塵濃度、溫度和濕度,對(duì)得到的數(shù)據(jù)進(jìn)行存儲(chǔ)分析和處理。
[Abstract]:With the development of industry, it brings a lot of convenience to people's life. However, there are many harmful factors in the process of industrial production, such as coal mining, cement production and other industries of dust pollution. Among all kinds of harmful factors, it has the most serious influence on human health. Dust is the most direct harm to the human body, the most serious is caused by pneumoconiosis. When the dust concentration is too high, it may explode when it is dry at high temperature. Therefore, temperature and humidity are also an important reference factor. The embedded detection system of dust concentration and temperature and humidity is based on dust detection technology, temperature and humidity detection technology, Ethernet transmission technology, 3G wireless transmission technology and so on. With ARM as the core, the data processing, display, storage and communication collected by the sensor are mainly realized. According to the reflection principle of light, when the dust particles pass through the internal beam of the sensor, the sensor obtains the corresponding dust concentration by measuring the intensity of the reflected light. The temperature and humidity sensor converts the temperature signal and humidity signal into electrical signal, through signal conditioning and AD conversion, and finally obtains the corresponding concentration value. Arm sends instructions according to the timing of the sensor to obtain the corresponding concentration value. First of all, the local display and storage are carried out, and then the data is transmitted to the upper computer through Ethernet or 3G wireless module. After the upper computer gets the data, the data is stored and analyzed. If there is data beyond the range or abnormal timely alarm. To achieve the purpose of real-time monitoring of data. In terms of hardware, Samsung ARM9 chip S3C2440 is used as the processor. With the corresponding external SDRAM and external NORFLAS-II, the dust sensor GP2Y1010AUOF and the temperature and humidity sensor SHT11 based on the principle of light reflection are used to collect the data. Arm obtains the final results through acquisition and calculation. Then the data is stored and processed to PC through Ethernet and 3G module. In the aspect of software, it is divided into upper computer and lower computer. The lower computer is mainly composed of u COS-II embedded operating system and each task module on this system. The lower computer mainly drives each sensor module to collect data, and then sends the data to the upper computer through TCP/IP protocol or 3G module. The upper computer is based on delphi platform, mainly receives the dust concentration, temperature and humidity sent by the lower computer, and stores and processes the obtained data.
