【摘要】：伴隨著我國(guó)國(guó)民經(jīng)濟(jì)的不斷發(fā)展，工業(yè)化水平的逐步提高，氣候變化和環(huán)境問(wèn)題日益凸顯，國(guó)家對(duì)氣象服務(wù)和環(huán)境監(jiān)測(cè)業(yè)務(wù)愈加重視，而目前國(guó)內(nèi)的氣象監(jiān)測(cè)系統(tǒng)多數(shù)采用人工式或有線式數(shù)據(jù)采集，這些方式不僅存在效率低、實(shí)時(shí)性差的缺點(diǎn)，且在較大程度上限制了應(yīng)用場(chǎng)合的擴(kuò)展。 本論文在系統(tǒng)討論GPRS通信技術(shù)以及各氣象要素傳感器檢測(cè)原理的基礎(chǔ)上，提出了一種基于GPRS遠(yuǎn)程通訊的低功耗、點(diǎn)對(duì)多點(diǎn)式氣象數(shù)據(jù)采集傳輸系統(tǒng)設(shè)計(jì)方案。該系統(tǒng)架構(gòu)整體由三大部分構(gòu)成，分別為數(shù)據(jù)采集部分、遠(yuǎn)程傳輸部分和存儲(chǔ)顯示部分。數(shù)據(jù)采集部分以STC12C5A60S2單片機(jī)為核心，外圍傳感器負(fù)責(zé)環(huán)境風(fēng)向、風(fēng)速、溫度、濕度、光照和氣壓數(shù)據(jù)的采集工作，按照該理念設(shè)計(jì)相應(yīng)的硬件電路，包括主控制電路、電源電路、信號(hào)采集和通信部分電路。遠(yuǎn)程傳輸部分則由傳輸終端和服務(wù)器組成，傳輸終端以ARM9為控制中心，，通過(guò)無(wú)線路由與服務(wù)器建立基于GPRS和Internet的網(wǎng)絡(luò)連接，并利用Socket實(shí)現(xiàn)數(shù)據(jù)交互。數(shù)據(jù)的存儲(chǔ)顯示部分則基于PostgreSQL數(shù)據(jù)庫(kù)技術(shù)和JAVA工具實(shí)現(xiàn)氣象數(shù)據(jù)的實(shí)時(shí)查看、歷史記錄查詢以及圖形界面顯示的功能。 系統(tǒng)在軟件方面的設(shè)計(jì)主要由四部分組成，分別為：數(shù)據(jù)采集軟件設(shè)計(jì)、遠(yuǎn)程傳輸客戶端軟件設(shè)計(jì)、遠(yuǎn)程傳輸服務(wù)器端軟件設(shè)計(jì)以及人機(jī)交互圖形界面軟件設(shè)計(jì)。 該課題從客觀需求出發(fā)，實(shí)現(xiàn)了多種氣象信息采集、傳輸和遠(yuǎn)程監(jiān)控的自動(dòng)化。整套系統(tǒng)以其功耗小、價(jià)格低、實(shí)現(xiàn)簡(jiǎn)易、擴(kuò)展性強(qiáng)等特點(diǎn)，在環(huán)境監(jiān)測(cè)行業(yè)中具備廣闊應(yīng)用前景。
[Abstract]:With the continuous development of our national economy and the gradual improvement of industrialization level, climate change and environmental problems become increasingly prominent, and the state pays more and more attention to meteorological services and environmental monitoring. At present, most meteorological monitoring systems in China adopt artificial or wired data acquisition. These methods not only have the shortcomings of low efficiency and poor real-time performance, but also limit the expansion of applications to a large extent. Based on the systematic discussion of GPRS communication technology and the detection principle of meteorological element sensors, a low power point to multi-point meteorological data acquisition and transmission system based on GPRS remote communication is proposed in this paper. The architecture of the system consists of three parts: data acquisition, remote transmission and storage and display. The data acquisition part is based on STC12C5A60S2 single chip microcomputer. The peripheral sensors are responsible for collecting the data of wind direction, wind speed, temperature, humidity, illumination and air pressure. According to this concept, the corresponding hardware circuits are designed, including the main control circuit and the power circuit. Signal acquisition and communication circuit. The remote transmission part is composed of the transmission terminal and the server. The transmission terminal takes ARM9 as the control center, establishes the network connection based on GPRS and Internet with the server through the wireless route, and realizes the data exchange using Socket. The data storage and display part is based on PostgreSQL database technology and JAVA tools to realize the real-time view of meteorological data, history query and graphical interface display function. The software design of the system consists of four parts: data acquisition software design, remote transmission client software design, remote transmission server software design and human-computer interactive graphical interface software design. Based on the objective demand, the subject realizes the automation of many meteorological information collection, transmission and remote monitoring. Because of its advantages of low power consumption, low price, easy implementation and strong expansibility, the whole system has a broad application prospect in the environmental monitoring industry.
