【摘要】：隨著經(jīng)濟的快速發(fā)展和人們生活品質(zhì)的不斷提高,工業(yè)和生活用水量不斷增加,城市供水系統(tǒng)管網(wǎng)的分布越來越廣,管網(wǎng)上的監(jiān)測點、泵站數(shù)量也在不斷增加,這對供水管網(wǎng)系統(tǒng)的監(jiān)控提出了更高的要求。如何利用現(xiàn)代計算機技術(shù)、通訊技術(shù)、網(wǎng)絡(luò)技術(shù)和自動控制技術(shù),特別是采用無線通信與計算機監(jiān)控管理技術(shù)相結(jié)合的方法,實現(xiàn)對城市、鄉(xiāng)村的綜合供水管網(wǎng),及時有效的進(jìn)行管網(wǎng)遠(yuǎn)程數(shù)據(jù)信息實時采集、傳輸、數(shù)據(jù)回溯和分析、以及生產(chǎn)科學(xué)管理,是本課題的主要任務(wù)和研究內(nèi)容。本文根據(jù)呂梁某供水公司供水管網(wǎng)工藝流程和控制要求,對其供水管網(wǎng)遠(yuǎn)程監(jiān)控系統(tǒng)進(jìn)行了系統(tǒng)設(shè)計。由于其系統(tǒng)管網(wǎng)采用分段輸水方案,供水管線上共設(shè)有減壓池站、管道監(jiān)測點、分水口站以及加壓泵站等主要重點實施監(jiān)控站點。本文在對以往供水管網(wǎng)監(jiān)控方案缺點進(jìn)行總結(jié)的過程中,制定了較為經(jīng)濟合理的基于PPI協(xié)議和GPRS網(wǎng)絡(luò)的供水管網(wǎng)遠(yuǎn)程監(jiān)控方案。該方案采用SCADA系統(tǒng)模式的分層結(jié)構(gòu)設(shè)計,即系統(tǒng)分為監(jiān)控系統(tǒng)、測控系統(tǒng)和通信網(wǎng)絡(luò)三部分。監(jiān)控系統(tǒng)采用力控組態(tài)軟件作為控制主站完成數(shù)據(jù)監(jiān)控;測控系統(tǒng)采用PLC作為現(xiàn)場控制從站完成數(shù)據(jù)采集與設(shè)備控制;通信網(wǎng)絡(luò)則采用PPI協(xié)議和GPRS網(wǎng)絡(luò)完成數(shù)據(jù)傳輸,其中數(shù)據(jù)通信鏈路的建立與維護(hù)則由GPRS DTU無線終端設(shè)備負(fù)責(zé)。該方案不僅實現(xiàn)了各站點單機控制,還重點解決了各站點組網(wǎng)聯(lián)控問題,實現(xiàn)了系統(tǒng)供水管網(wǎng)設(shè)備的全自動運行。同時本文還詳細(xì)的闡述了加壓泵站的變頻恒壓供水控制子系統(tǒng)和系統(tǒng)無線通信網(wǎng)絡(luò)設(shè)計。該監(jiān)控系統(tǒng)能充分發(fā)揮各個供水管網(wǎng)設(shè)備的性能,使設(shè)備維持在最佳運行工況點,實現(xiàn)管網(wǎng)設(shè)備的優(yōu)化組合運行,減少故障損失,從而降低系統(tǒng)運行和維護(hù)成本。本文設(shè)計的供水管網(wǎng)遠(yuǎn)程監(jiān)控系統(tǒng)實時性好,數(shù)據(jù)傳輸準(zhǔn)確,自動化程度高。目前,該系統(tǒng)已在供水公司投入運行,實踐表明該系統(tǒng)的性能是優(yōu)越和穩(wěn)定的,實現(xiàn)了系統(tǒng)預(yù)期的各項指標(biāo),取得了良好的企業(yè)效益,為供水管網(wǎng)的安全生產(chǎn)提供了保障。同時本論文的研究設(shè)計成果對于我國工業(yè)供水行業(yè)而言也有著很好的實用意義和參考價值。
[Abstract]:With the rapid development of economy and the continuous improvement of people's quality of life, the amount of water used in industry and daily life is increasing, the distribution of urban water supply network is more and more extensive, the number of monitoring points and pumping stations on the pipe network is also increasing. This puts forward higher requirements for the monitoring of water supply network system. How to use modern computer technology, communication technology, network technology and automatic control technology, especially the method of combining wireless communication with computer monitoring and management technology, to realize the integrated water supply network in cities and villages, It is the main task and research content of this subject to collect, transmit, trace and analyze the data in real time, and to manage the production scientifically. According to the technological process and control requirements of water supply network in a water supply company of Lv Liang, the system design of remote monitoring system for water supply network is carried out in this paper. As a result of its system pipe network adopts the section water conveyance plan, the water supply pipeline altogether has the decompression pool station, the pipeline monitoring point, the sub-water mouth station and the pressurized pump station and so on the main key implementation monitoring station. In the process of summarizing the shortcomings of the previous monitoring schemes of water supply network, this paper formulates a more economical and reasonable remote monitoring scheme based on PPI protocol and GPRS network. The scheme adopts the hierarchical structure of SCADA system, that is, the system is divided into three parts: monitoring system, measurement and control system and communication network. The monitoring system uses the force control configuration software as the main control station to complete the data monitoring, PLC as the field control station to complete the data acquisition and equipment control, and the communication network uses the PPI protocol and GPRS network to complete the data transmission. The establishment and maintenance of data communication link is the responsibility of GPRS DTU wireless terminal equipment. This scheme not only realizes the single machine control of each station, but also solves the problem of the network connection control of each station, and realizes the automatic operation of the water supply network equipment of the system. At the same time, the design of frequency conversion constant pressure water supply control subsystem and system wireless communication network of pressurized pump station are described in detail. The monitoring system can give full play to the performance of the water supply network equipment, make the equipment maintain at the best operating condition, realize the optimal combined operation of the pipe network equipment, reduce the failure loss, and thus reduce the operation and maintenance cost of the system. The remote monitoring system of water supply network designed in this paper has the advantages of good real-time, accurate data transmission and high degree of automation. At present, the system has been put into operation in the water supply company. The practice shows that the system performance is superior and stable, realizes the expected indexes of the system, obtains good enterprise benefit, and provides the guarantee for the safe production of the water supply network. At the same time, the research and design results of this paper have good practical significance and reference value for China's industrial water supply industry.
