【摘要】：當今社會正在步入網(wǎng)絡時代，Internet已經(jīng)成為重要的信息傳輸載體。雖然目前，大部分網(wǎng)絡終端仍以PC的形式出現(xiàn)，但是作為計算機應用發(fā)展趨勢——嵌入式系統(tǒng)正在異軍突起，并且已經(jīng)擁有了大量的8、16、32位嵌入式微控制器的應用產品。嵌入式設備接入Internet正在成為一種趨勢，并且顯示出強大的生命力和廣闊的應用前景。 近年來，溫室大棚種植為提高人們的生活水平帶來了極大的便利，得到了迅速的推廣和應用。種植環(huán)境中的溫度、濕度、光照度等環(huán)境因子對農作物的生長起著很大的影響。傳統(tǒng)的監(jiān)測方法是在溫室大棚中布置大量的傳感器節(jié)點，通過RS－485總線將采集信息傳輸?shù)焦た貦C上進行處理，這種方法需要在溫室大棚中鋪設通信線路來傳遞監(jiān)測信息。但這種方法給現(xiàn)場安裝和維護帶來了不便，同時也難以廣域地查詢某地溫室大棚內的實時環(huán)境數(shù)據(jù)。移動無線通信技術的發(fā)展，實現(xiàn)了農業(yè)信息與互聯(lián)網(wǎng)（Internet）“最后1km”的無縫連接，為遠程信息的獲取、傳輸與交換提供了有效的途徑，，其中GPRS技術因其具有“傳輸質量高”、“永遠在線”和“通信費用低”等優(yōu)點，得到了廣泛的應用。 本文基于嵌入式Internet技術，設計并研究了以PIC16F873A為MCU的溫室大棚環(huán)境參數(shù)（溫度、濕度、光照度）采集模塊，并以GPRS網(wǎng)絡方式接入Internet，實現(xiàn)了在Internet客戶端對遠程溫室大棚內環(huán)境參數(shù)的實時監(jiān)測。 本文研究的主要工作及取得的成果如下： 1.簡要論述了嵌入式Internet技術的現(xiàn)狀與發(fā)展，介紹了各種嵌入式設備接入Internet方案的特點，選定了以GPRS網(wǎng)絡技術將嵌入式設備接入Internet的方案。 2.研究設計了以PC機為上位機，以MCU-PIC16F873A為下位機，基于嵌入式Internet的溫室大棚監(jiān)測系統(tǒng)模型。著重研究和設計了以PIC16F873A為控制核心的下位機——溫室大棚自動監(jiān)測節(jié)點。 3.研究利用GPRS網(wǎng)絡將嵌入式設備以無線方式接入Internet的模式。嵌入式設備以8位單片機為核心，將GPRS模塊透明化——構建溫室內環(huán)境參數(shù)的透明傳輸，實現(xiàn)低檔單片機與遠程PC機之間的直接交互。 本文的研究結果，為嵌入式Internet技術在遠程溫室大棚環(huán)境參數(shù)監(jiān)測的研究中的一次基礎性探索，具有一定的實踐意義。
[Abstract]:At present, the Internet has become an important carrier of information transmission. Although most of the network terminals still appear in the form of PC, as the development trend of computer application, embedded system is emerging. The embedded device access to Internet is becoming a trend, and has shown a strong vitality and broad application prospects. In recent years, greenhouse planting has brought great convenience to improve people's living standard, and has been rapidly popularized and applied. The traditional monitoring method is to arrange a large number of sensor nodes in the greenhouse and transmit the collected information to the industrial control computer through the RS-485 bus for processing. This method requires laying communication lines in greenhouses to transmit monitoring information. However, this method brings inconvenience to installation and maintenance on the spot. At the same time, it is difficult to query real-time environmental data in a greenhouse in a wide area. With the development of mobile wireless communication technology, the "last 1km" connection between agricultural information and Internet has been realized, so as to obtain remote information. Transmission and exchange provide an effective way, among which GPRS technology has been widely used because of its advantages of "high transmission quality", "always online" and "low communication cost". Based on embedded Internet technology, this paper designs and studies the collection module of greenhouse environment parameters (temperature, humidity, illumination) based on PIC16F873A as MCU. The GPRS network is used to access the Internet to realize the real-time monitoring of the environmental parameters in the remote greenhouse in the Internet client. The main work and achievements of this paper are as follows:. 1. The present situation and development of embedded Internet technology are briefly discussed, the characteristics of various embedded devices accessing Internet schemes are introduced, and the scheme of using GPRS network technology to access embedded devices to Internet is selected. 2. The model of greenhouse greenhouse monitoring system based on embedded Internet with PC as upper computer and MCU-PIC16F873A as lower computer is studied and designed. The automatic monitoring node of greenhouse greenhouse based on PIC16F873A is studied and designed. 3. The mode of wireless access of embedded devices to Internet using GPRS network is studied. The embedded devices take 8-bit single chip microcomputer as the core, and make the GPRS module transparent to construct the transparent transmission of environmental parameters in greenhouse. Realize the direct interaction between the low-grade single-chip computer and the remote PC. The results of this paper are of practical significance for the research of embedded Internet technology in the study of remote greenhouse environmental parameters monitoring.
