2、戶或控制系統(tǒng)，為提高產(chǎn)品質(zhì)量、降低成本提供信息和手段；在科學(xué)研究上，數(shù)據(jù)采集系統(tǒng)可以為我們提供大量的動態(tài)信息，成為探索科學(xué)奧秘的重要手段。目前，數(shù)據(jù)采集幾乎無孔不入，它已滲透到了地質(zhì)、醫(yī)藥器械、雷達(dá)、通訊、遙感遙測等各個(gè)領(lǐng)域，為我們更好的獲取信息提供了良好的基礎(chǔ)。 無線數(shù)據(jù)采集特別適用于復(fù)雜地形條件、高腐蝕性、建筑群、爆炸等場合，或者被采集對象是運(yùn)動、旋轉(zhuǎn)等情況。隨著數(shù)字電路和射頻電路制作工藝、低功耗電路、高能電池、微電子技術(shù)及集成電路技術(shù)的進(jìn)步，無線通信技術(shù)取得了飛速的發(fā)展，無線通信的實(shí)現(xiàn)越來越容易，傳輸速度越來越快，可靠性越來越高，并且逐漸達(dá)到可以和有線網(wǎng)絡(luò)相媲美的水平。 無線傳輸越來越多

3、的被應(yīng)用在工業(yè)及民用的數(shù)據(jù)采集上，解決了一些布線復(fù)雜、甚至無法布線的情況。無線方式具有如下幾個(gè)顯著的特點(diǎn)：傳輸介質(zhì)采用的是電磁波，節(jié)省了架設(shè)電纜的所需的占地和各種花費(fèi)及其給其他建筑的建設(shè)帶來的不便，應(yīng)用起來更加方便；在應(yīng)用單片機(jī)編解碼接口技術(shù)的無線通信系統(tǒng)中，采用多字節(jié)地址編碼，收發(fā)器的數(shù)量不受限制；具有電路簡單、功耗小、體積小、成本低等優(yōu)點(diǎn)，非常便于使用；設(shè)計(jì)設(shè)施都很簡便適合更換場合反復(fù)利用。 溫度作為一個(gè)重要的物理量，是工業(yè)生產(chǎn)過程中最普遍、最重要的工藝參數(shù)之一。隨著工業(yè)的不斷發(fā)展，對溫度測量的要求越來越高，而且測量的范圍也越來越廣，對溫度的檢測技術(shù)的要求也越來越高。因此，溫度測量的研究也

4、是一個(gè)重要的研究課題。 總之，本課題將數(shù)據(jù)采集與無線傳輸相結(jié)合，發(fā)揮無線傳輸?shù)膬?yōu)勢，并且解決硬件、軟件及通信協(xié)議優(yōu)化等問題。二、課題研究現(xiàn)狀（1）國外溫度測控系統(tǒng)研究國外對溫度控制技術(shù)研究較早，始于20世紀(jì)70年代。先是采用模擬式的組合儀表，采集現(xiàn)場信息并進(jìn)行指示、記錄和控制。80年代末出現(xiàn)了分布式控制系統(tǒng)。目前正開發(fā)和研制計(jì)算機(jī)數(shù)據(jù)采集控制系統(tǒng)的多因子綜合控制系統(tǒng)?，F(xiàn)在世界各國的溫度測控技術(shù)發(fā)展很快，一些國家在實(shí)現(xiàn)自動化的基礎(chǔ)上正向著完全自動化、無人化的方向發(fā)展。（2）國內(nèi)溫度測控系統(tǒng)研究我國對于溫度測控技術(shù)的研究較晚，始于20世紀(jì)80年代。我國工程技術(shù)人員在吸收發(fā)達(dá)國家溫度測控技術(shù)的基礎(chǔ)上

5、，才掌握了溫度室內(nèi)微機(jī)控制技術(shù)，該技術(shù)僅限于對溫度的單項(xiàng)環(huán)境因子的控制。我國溫度測控設(shè)施計(jì)算機(jī)應(yīng)用，在總體上正從消化吸收、簡單應(yīng)用階段向?qū)嵱没?、綜合性應(yīng)用階段過渡和發(fā)展。在技術(shù)上，以單片機(jī)控制的單參數(shù)單回路系統(tǒng)居多，尚無真正意義上的多參數(shù)綜合控制系統(tǒng)，與發(fā)達(dá)國家相比，存在較大差距。我國溫度測量控制現(xiàn)狀還遠(yuǎn)遠(yuǎn)沒有達(dá)到工廠化的程度，生產(chǎn)實(shí)際中仍然有許多問題困擾著我們，存在著裝備配套能力差，產(chǎn)業(yè)化程度低，環(huán)境控制水平落后，軟硬件資源不能共享和可靠性差等缺點(diǎn)。三、課題研究發(fā)展趨勢隨著移動通信需求和遠(yuǎn)程數(shù)據(jù)采集量的增加，加之有線傳輸?shù)馁M(fèi)用日益增長，人們正逐漸認(rèn)識到在許多檢測領(lǐng)域采用無線傳輸?shù)谋匾?。在過

6、去的幾年中，無線通訊領(lǐng)域取得了很大的進(jìn)展，這其中包括數(shù)字電路和射頻電路制作工藝的進(jìn)步、低功耗電路、高能電池以及微電子技術(shù)的采用。以上諸多方面的發(fā)展使移動通信設(shè)備更加靈巧、經(jīng)濟(jì)、可靠。與上述技術(shù)一樣，數(shù)字通信技術(shù)和數(shù)字調(diào)制技術(shù)的發(fā)展也發(fā)揮了很大的作用，他們使無線通信網(wǎng)絡(luò)向更加經(jīng)濟(jì)、更加容易操作的方向發(fā)展。所以如果我們能夠很好地了解無線通信的基本原則以及這些技術(shù)的特點(diǎn)，就能更好地理解并完成傳感數(shù)據(jù)的無線采集。無線數(shù)據(jù)通信技術(shù)可分為兩大類：一是基于蜂窩的接入技術(shù)，如蜂窩數(shù)字分組數(shù)據(jù)(CDPD)，通用分組無線傳輸技術(shù)(GPRS) 、EDGE 等。二是基于局域網(wǎng)的技術(shù)，如 IEEE802.11 WLAN

7、、藍(lán)牙技術(shù)Bluetooth）、紅外通信技術(shù)（IrDA）、微功率短距離無線通信技術(shù)等。與目前已經(jīng)具備相當(dāng)規(guī)模的無線長距離通信網(wǎng)絡(luò)相比，短距離無線通信系統(tǒng)在基本結(jié)構(gòu)、服務(wù)范圍、應(yīng)用層次及通信業(yè)務(wù)(數(shù)據(jù)、話音)上，均有很大的不同。四、課題研究（論文）研究方案及工作計(jì)劃（含工作重點(diǎn)與難點(diǎn)及擬采用的途徑）研究方案：在這次課題研究中，溫度的檢測有許多方法，可供選擇的器件和運(yùn)用的技術(shù)也有多種。因此，系統(tǒng)的總體設(shè)計(jì)方案應(yīng)在滿足系統(tǒng)整體性能指標(biāo)的前提下，充分考慮系統(tǒng)使用的環(huán)境，所選的結(jié)構(gòu)要盡量簡單實(shí)用、易于實(shí)現(xiàn)，器件的選用要著眼于合適的參數(shù)、穩(wěn)定的性能、較低的功耗、低廉的成本以及較好的互換性能。重點(diǎn)：1、溫度

43、數(shù)據(jù)采集設(shè)備和系統(tǒng)多屬于專用的系統(tǒng)。20世紀(jì)70年代后期，隨著微型機(jī)的發(fā)展，誕生了采集器、儀表同計(jì)算機(jī)溶為一體的數(shù)據(jù)采集系統(tǒng)。由于這種數(shù)據(jù)采集系統(tǒng)的性能優(yōu)良，超過了傳統(tǒng)的自動檢測儀表和專用數(shù)據(jù)采集系統(tǒng)，因而獲得了驚人的發(fā)展。從70年代起，數(shù)據(jù)采集系統(tǒng)發(fā)展過程中逐漸分為兩類，一類是實(shí)驗(yàn)室數(shù)據(jù)采集系統(tǒng)，一類是工業(yè)現(xiàn)場數(shù)據(jù)采集系統(tǒng)。 20世紀(jì)80年代隨著計(jì)算機(jī)的普及應(yīng)用，數(shù)據(jù)采集系統(tǒng)得到了很大的發(fā)展，開始出現(xiàn)了通用的數(shù)據(jù)采集與自動測試系統(tǒng)。該階段的數(shù)據(jù)采集系統(tǒng)主要有兩類，一類以儀表儀器和采集器、通用接口總線和計(jì)算機(jī)組成。這類系統(tǒng)主要應(yīng)用于實(shí)驗(yàn)室，在工業(yè)生產(chǎn)現(xiàn)場也有一定的應(yīng)用。第二類以數(shù)據(jù)采集卡、標(biāo)準(zhǔn)

44、總線和計(jì)算機(jī)構(gòu)成，這一類在工業(yè)現(xiàn)場應(yīng)用較多。20世紀(jì)80年代后期，數(shù)據(jù)采集發(fā)生了很大的變化，工業(yè)計(jì)算機(jī)、單片機(jī)和大規(guī)模集成電路的組合，用軟件管理，是系統(tǒng)的成本減低，體積變小，功能成倍增加，數(shù)據(jù)處理能力大大加強(qiáng)。 20世紀(jì)90年代至今，在國際上技術(shù)先進(jìn)的國家，數(shù)據(jù)采集系統(tǒng)已成功的運(yùn)用到軍事、航空電子設(shè)備及宇航技術(shù)、工業(yè)等領(lǐng)域。由于集成電路制造技術(shù)的不斷提高，出現(xiàn)了高性能、高可靠的單片機(jī)數(shù)據(jù)采集系統(tǒng)（DAS）。數(shù)據(jù)采集技術(shù)已經(jīng)成為一種專門的技術(shù)，在工業(yè)領(lǐng)域得到了廣泛的應(yīng)用。該階段的數(shù)據(jù)采集系統(tǒng)采用模塊式結(jié)構(gòu)，根據(jù)不同的應(yīng)用要求，通過簡單的增加和更改模塊，并結(jié)合系統(tǒng)編程，就可擴(kuò)展或修改系統(tǒng)，迅速組成

45、一個(gè)新的系統(tǒng)。盡管現(xiàn)在以微機(jī)為核心的可編程數(shù)據(jù)采集與處理采集技術(shù)的發(fā)展方向得到了迅速的發(fā)展，而且組成一個(gè)數(shù)據(jù)采集系統(tǒng)只需要一塊數(shù)據(jù)采集卡，把它插在微機(jī)的擴(kuò)展槽內(nèi)并輔以應(yīng)用軟件，就能實(shí)現(xiàn)數(shù)據(jù)采集功能，但這并不會對基于單片機(jī)為核心的數(shù)據(jù)采集系統(tǒng)產(chǎn)生影響。相較于數(shù)據(jù)采集板卡成本和功能的限制，單片機(jī)具多功能、高效率、高性能、低電壓、低功耗、低價(jià)格等優(yōu)點(diǎn)，而雙單片機(jī)又具有精度較高、轉(zhuǎn)換速度快、能夠?qū)Χ帱c(diǎn)同時(shí)進(jìn)行采集，因此能夠開發(fā)出能滿足實(shí)際應(yīng)用要求的、電路結(jié)構(gòu)簡單的、可靠性高的數(shù)據(jù)采集系統(tǒng)。這就使得以單片機(jī)為核心的數(shù)據(jù)采集系統(tǒng)在許多領(lǐng)域得到了廣泛的應(yīng)用。在日常生活和工作中，我們常常用到溫度控制，溫度控制

46、系統(tǒng)廣泛應(yīng)用于汽車, 鍋爐, 電子, 化工等各個(gè)領(lǐng)域。早期常用的一些溫度控制系統(tǒng)都使用模擬電路設(shè)計(jì)制作的，有些使用熱敏電阻，有些使用鉑電阻，有些使用熱電偶，還有些使用PN結(jié)，其準(zhǔn)確性和精度都不是很理想，現(xiàn)在基本上都是基于數(shù)字技術(shù)的新一代產(chǎn)品，這種產(chǎn)品功能強(qiáng)，是前者的換代之物。隨著單片機(jī)性能價(jià)格比的不斷提高，新一代產(chǎn)品的應(yīng)用也越來越廣泛，大可構(gòu)成復(fù)雜的工業(yè)過程控制系統(tǒng)，完成復(fù)雜的控制功能。小則可以用于家電控制，甚至可以用于兒童電子玩具。它功能強(qiáng)大，體積小，質(zhì)量輕，靈活好用，配以適當(dāng)?shù)慕涌谛酒?，可以?gòu)造各種各樣、功能各異的微電子產(chǎn)品。在本設(shè)計(jì)上按照個(gè)人的意圖稍加擴(kuò)展，就可以實(shí)現(xiàn)更多更強(qiáng)大的功能。隨著社會的發(fā)展、科技的進(jìn)步以及人們生活水平的逐步提高，現(xiàn)如今自動化、信息化程度越來越高，單片機(jī)和傳感器的應(yīng)用領(lǐng)域越來越廣。各種方便于生活的自動控制系統(tǒng)進(jìn)入了人們的生活。單片機(jī)和傳感器在自動控制中的應(yīng)用越來越廣泛，它實(shí)用性強(qiáng)，使用方便，技術(shù)先進(jìn)，它們的廣泛應(yīng)用是科技進(jìn)步的標(biāo)志。 現(xiàn)實(shí)中溫度控制不適當(dāng)導(dǎo)致的發(fā)霉，腐爛問題是倉庫日常工作急需解決的問題，是衡量倉庫管理質(zhì)量的重要指標(biāo)。它直接影響到儲備物資的使用壽命
