As a highspeed, efficient and costeffective wireless system,GPRS has a wide range of network coverage, wide data bandwidth, adaptable, denominated by the data flow calculation advantage, the advantages of realtime online, especially for intermittent, and sudden or frequent , And a small amount of data transfer, but also for the occasional large amounts of data transmission, data collection and monitoring to meet the twoway data transmission. GPRS technology from the laboratory studies, areas to the official business within the trial, after a long, technologically advanced and reliable. GPRS equipment data monitoring terminal transmission equipment can automatically attach a boot to the GPRS network, and data centers for realtime data in realtime online munication, highspeed transmission and high reliability.In this paper, design a temperature control system, with the microcontroller as the microcontroller the choice of digital temperature sensors, temperature control, a GPRSbased technology solutions for remote temperature monitoring system, using AT89C51 microcontroller and digital temperature sensor for field DS18B20 Temperature data acquisition and processing, and through the GPRS module TC39i remote data transmission and reception, with high accuracy, good stability. Hardware design of a microcontrollerbased smart temperature control system to AT89C51 microcontroller as the core, using a temperature sensor DS18B20, the GPRSbased wireless munication module, based on AT mands and data acquisition, to build a remote temperature data acquisition system For temperature controlThe results show the good effect of the system and have broad application prospects.Key Words:Temperature acquisition system, monitoring software, Microcontrolle目 錄1. 概 述 5 課題設(shè)計背景 5 課題設(shè)計意義 52. 系統(tǒng)的總體結(jié)構(gòu)與硬件電路設(shè)計 6 系統(tǒng)總體結(jié)構(gòu)設(shè)計 6 溫度采集模塊設(shè)計 6 單片機電路設(shè)計 8 通信電路設(shè)計 12 14 下位機總體軟件的設(shè)計 14 16 18 22 GPRS通信網(wǎng)絡(luò) 22 遠(yuǎn)程溫度檢測的實現(xiàn)原理 23 GPRS DTU 遠(yuǎn)程溫度監(jiān)測界面 24 25 27致 謝 29附錄1:采集系統(tǒng)接線圖 30附錄2:元器件表 31鹽城工學(xué)院本科生畢業(yè)說明書( 2011)1. 概 述 課題設(shè)計背景溫度與人們的生產(chǎn)生活密切相關(guān),需要對溫度監(jiān)測的場合非常多。實踐結(jié)果表明,該系統(tǒng)使用效果良好,有著廣泛的應(yīng)用前景。文中設(shè)計了一種溫度控制系統(tǒng),用單片機作為微控器,選用數(shù)字溫度傳感器,對溫度進(jìn)行控制,提出了一種基于GPRS技術(shù)的遠(yuǎn)程溫度監(jiān)測系統(tǒng)方案,采用AT89C51單片機和DS18B20數(shù)字溫度傳感器實現(xiàn)現(xiàn)場溫度數(shù)據(jù)的采集和處理,再通過GPRS模塊TC39i實現(xiàn)遠(yuǎn)程的數(shù)據(jù)傳輸和接收,具有精度高、穩(wěn)定性好的特點。GPRS技術(shù)從實驗室研究、地區(qū)范圍內(nèi)試用到正式商用,經(jīng)過了長時間的完善,技術(shù)先進(jìn)可靠。因而設(shè)計一種較為理想的溫度控制系統(tǒng)是非常有價值的。有些工藝過程對其溫度的控制效果直接影響著產(chǎn)品的質(zhì)量。畢業(yè)設(shè)計說明書基于GPRS的遠(yuǎn)程溫度監(jiān)測系統(tǒng)設(shè)計專業(yè)自動化學(xué)生姓名班級B自動化074學(xué)號指導(dǎo)教師完成日期2010年6月3日3基于GPRS的遠(yuǎn)程溫度監(jiān)測系統(tǒng)設(shè)計摘 要溫度是工業(yè)生產(chǎn)中主要的被控參數(shù)之一,與之相關(guān)的各種溫度控制系統(tǒng)廣泛應(yīng)用于冶金、化丁、機械、食品等領(lǐng)域。溫度控制是丁業(yè)生產(chǎn)過程中經(jīng)常遇到的過程控制。例如:在冶金工業(yè)、化工生產(chǎn)、電力工程、造紙行業(yè)、機械制造和食品加工等諸多領(lǐng)域中,人們都需要對各類加熱爐、熱處理爐、反應(yīng)爐和鍋爐中的溫度進(jìn)行檢測和控制;在農(nóng)業(yè)生產(chǎn)、糧食儲備、計算機機房等都需要對溫度進(jìn)行控制。GPRS作為一種高速、高效、經(jīng)濟的無線系統(tǒng),具有網(wǎng)絡(luò)覆蓋范圍廣、數(shù)據(jù)帶寬寬、適應(yīng)性強、計價按數(shù)據(jù)流量計算、實時在線的優(yōu)點,特別適用于間斷的、突發(fā)性的或頻繁的、少量的數(shù)據(jù)傳輸,也適用于偶爾大量的數(shù)據(jù)傳輸,能夠滿足數(shù)據(jù)采集及監(jiān)控的雙向數(shù)據(jù)信息傳輸。GPRS設(shè)備數(shù)據(jù)監(jiān)控終端傳輸設(shè)備一開機就能自動附著到GPRS網(wǎng)絡(luò)上,與數(shù)據(jù)中心實時在線進(jìn)行實時數(shù)據(jù)通信,高速輸,可靠性高。硬件方面設(shè)計了一個基于單片機的溫度智能控制系統(tǒng), 以AT89C51單片機為核心,采用了溫度傳感器DS18B20,以GPRS無線通信模塊為基礎(chǔ),基于AT指令和數(shù)據(jù)采集器,構(gòu)建一個遠(yuǎn)程的溫度數(shù)據(jù)采集系統(tǒng),對溫度進(jìn)行控制。關(guān)鍵詞:溫度采集系統(tǒng);監(jiān)控軟件;單片機 GPRSbased remote temperature monitoring systemAbstract:Temperature is the main accused in the industrial pro
