【摘要】：随着经济的快速发展和人们生活品质的不断提高,工业和生活用水量不断增加,城市供水系统管网的分布越来越广,管网上的监测点、泵站数量也在不断增加,这对供水管网系统的监控提出了更高的要求。如何利用现代计算机技术、通讯技术、网络技术和自动控制技术,特别是采用无线通信与计算机监控管理技术相结合的方法,实现对城市、乡村的综合供水管网,及时有效的进行管网远程数据信息实时采集、传输、数据回溯和分析、以及生产科学管理,是本课题的主要任务和研究内容。本文根据吕梁某供水公司供水管网工艺流程和控制要求,对其供水管网远程监控系统进行了系统设计。由于其系统管网采用分段输水方案,供水管线上共设有减压池站、管道监测点、分水口站以及加压泵站等主要重点实施监控站点。本文在对以往供水管网监控方案缺点进行总结的过程中,制定了较为经济合理的基于PPI协议和GPRS网络的供水管网远程监控方案。该方案采用SCADA系统模式的分层结构设计,即系统分为监控系统、测控系统和通信网络三部分。监控系统采用力控组态软件作为控制主站完成数据监控;测控系统采用PLC作为现场控制从站完成数据采集与设备控制;通信网络则采用PPI协议和GPRS网络完成数据传输,其中数据通信链路的建立与维护则由GPRS DTU无线终端设备负责。该方案不仅实现了各站点单机控制,还重点解决了各站点组网联控问题,实现了系统供水管网设备的全自动运行。同时本文还详细的阐述了加压泵站的变频恒压供水控制子系统和系统无线通信网络设计。该监控系统能充分发挥各个供水管网设备的性能,使设备维持在最佳运行工况点,实现管网设备的优化组合运行,减少故障损失,从而降低系统运行和维护成本。本文设计的供水管网远程监控系统实时性好,数据传输准确,自动化程度高。目前,该系统已在供水公司投入运行,实践表明该系统的性能是优越和稳定的,实现了系统预期的各项指标,取得了良好的企业效益,为供水管网的安全生产提供了保障。同时本论文的研究设计成果对于我国工业供水行业而言也有着很好的实用意义和参考价值。
[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.
