【正文】 (1)監(jiān)測(cè)點(diǎn)分散 ： 計(jì)量表廣泛分布，要求通信網(wǎng)絡(luò)應(yīng)該是覆蓋范圍較廣。大量寶貴的水資源被白白浪費(fèi)，一是無謂的消耗了資源 ； 二來增加了用水成本 ； 第二，管道滲漏更可能存在安全隱患，并有可能間接引起地下水污染。相應(yīng)地，對(duì)于自來水管道的實(shí)時(shí) 監(jiān)測(cè)也顯得越來越重要。從測(cè)控領(lǐng)域來講，由于現(xiàn)在監(jiān)測(cè)現(xiàn)場(chǎng)在地域上越來越分散，要對(duì)分散不同地域的監(jiān)測(cè)點(diǎn)進(jìn)行狀態(tài)監(jiān)測(cè)、遠(yuǎn)程數(shù)據(jù)采集、以及設(shè)備的診斷維護(hù)，只有通過遠(yuǎn)程通信網(wǎng)絡(luò)才能實(shí)現(xiàn)。s necessary to establish an effective realtime measure system for measuring and analyzing data of pipeline work of water supply, for the aim of scheduling the water resource properly, finding malfunction, avoiding hidden trouble and saving the tap water. By using the GPRS to transmit data gathered from pipeline work of water supply can get the aim for realtime measuring. GPRS (General Packet Radio Service), as the generation technology transition from 2 generation to 3 generation, is widely applied in industrial automation field. This paper presents a GPRSbased remote work monitoring system. The system uses GPRS work as the transmission platform of long distance signal, Combined with Visual Basic programming language with the wireless terminal DTU and data acquisition module RTU solved the wireless munication problem。最后闡述了本設(shè)計(jì)系統(tǒng)的優(yōu)點(diǎn)與不足，提出下一步改進(jìn)方向。本文提出一種基于 GPRS的 供水遠(yuǎn)程自動(dòng)化 監(jiān)控系統(tǒng)，該系統(tǒng)以 GPRS 網(wǎng)絡(luò)作為遠(yuǎn)程信號(hào)的傳輸平臺(tái)，并結(jié)合Visual Basic 語言程序與無線終端 DTU 及數(shù)據(jù)采集模塊 RTU 解決了監(jiān)控中的無線通信問題 ， 具有更好的可靠性和實(shí)時(shí)性。將分布采集的自來水管網(wǎng)數(shù)據(jù)，利用通用分組無線業(yè)務(wù) GPRS(General Packet Radio Service)進(jìn)行即時(shí)傳輸，達(dá)到對(duì) 供水系統(tǒng) 進(jìn)行實(shí)時(shí)監(jiān)控的目的?；?GPRS 的供水自動(dòng)化監(jiān)控系統(tǒng) Automation Measuring System for Water Supply Based on GPRS 基于 GPRS 的供水自動(dòng)化監(jiān)控系統(tǒng) 基于 GPRS 的供水自動(dòng)化監(jiān)控系統(tǒng) 摘 要 隨著工業(yè)技術(shù)的飛速發(fā)展和城市規(guī)模的不斷擴(kuò)大，城鎮(zhèn) 、 農(nóng)村 、 廠礦 、 油田等地的自來水用量正在急劇增長(zhǎng)， 供水系統(tǒng) 節(jié)點(diǎn)分布也越來越廣泛。建立一個(gè)有效的監(jiān)測(cè)系統(tǒng)，對(duì) 供水系統(tǒng) 進(jìn)行實(shí)時(shí)的數(shù)據(jù)測(cè)量與分析，以達(dá)到合理調(diào)度水資源分配、發(fā)現(xiàn)故障、消除隱患、節(jié)約水資源的目的，是非常必要的。 GPRS (General Packet Radio Service，通用分組無線業(yè)務(wù) )作為從 2G 向 3G過渡的 的技術(shù)，正在工業(yè)自動(dòng)化領(lǐng)域得到越來越廣泛的應(yīng)用。本文首先介紹了 GPRS 技術(shù)的基本原理，然后詳細(xì)描述了系統(tǒng) 的相關(guān)技術(shù)及硬件的參數(shù)和配置 ， 采用動(dòng)態(tài)域名解析解決了無固定 IP的問題， 并在此基礎(chǔ)上 詳細(xì)介紹了監(jiān)控中心軟件的實(shí)現(xiàn) 過程及各部分實(shí)現(xiàn)后的效果。 關(guān)鍵詞 ： 遠(yuǎn)程監(jiān)控 監(jiān)控中心 TCP/IP 協(xié)議 GPRS 基于 GPRS 的供水自動(dòng)化監(jiān)控系統(tǒng) Abstract Along with the fast progressing of industrial technology and the urban area, the usage amount of tap water is increasing rapidly, so as distributing scope of nodes in the p ipeline works of water supply. It39。 the real time and reliability is better. This paper firstly introduces the basic principle of GPRS technologies, describes the detailed system relevant technology and the parameters of hardware and configuration, using dynamic DNS solve the problem without a fixed IP, and on this basis introduces in detail the monitoring center software realization and the effect after all parts realization. Finally expounds the design system, and puts forward the advantages and shortings of next improving direction.
