【摘要】：计算机自动化监控系统是综合了计算机技术、通信技术、控制技术的综合性系统,广泛应用于现代工业控制领域,在我国各类供水系统中也得到了越来越多的应用。供水系统能够有效解决我国区域水资源分布不均的问题,对于我国国民经济发展具有重要的意义。当前的供水系统中,特别是越来越多的长距离供水系统中,其设备数量多、安装位置分散,能源消耗大,运行效率较低,管理水平不够高,发生事故后会造成较大的经济损失等问题,对于供水系统的高效安全运行和高水平管理提出了较大的挑战。在供水系统中引入计算机自动化监控系统,可以对供水系统进行远程监测和控制,及时有效的对系统进行管理控制,提高管理水平,减少维护费用,保证供水系统的安全运行。供水工程自动化监控系统组成结构复杂,涉及多学科,它的设计、开发和实现是一项复杂的系统工程。本论文基于组态王开发平台,结合山西省昔阳松溪供水工程实例,进行该供水系统计算机监控系统开发研究,主要研究内容为： 1).对工业现场自动化监控系统的现状和供水系统自动化监控系统的发展现状及基本结构进行研究,阐述了分层分布式监控系统结构的优势及其在供水系统中的应用。 2).分析了昔阳松溪供水工程自动化监控系统的设计需求,进行总体方案的设计,对常用的流量计和液位计从原理上进行了对比和分析,选用差压液位计和电磁流量计作为本工程的硬件设备；选用工业以太网搭建调度中心和控制子站的通信网络；现地控制单元选用西门子公司的CPU315-2PN/DN模块。 3).以组态王为软件平台,根据系统运行需求进行组态软件的开发,组态软件通过ODBC同SQL Server数据库进行连接,并通过组态王自带的SQL语言实现对数据库的写入和查询。 4).以VB语言作为平台开发系统运行分析软件,利用实测监控数据进行系统分析,拟合昔阳松溪供水工程中各水泵的流量扬程曲线、流量效率曲线和流量功率曲线,并且可以在监控系统中实时调用,以期为供水系统的运行提供技术支持；并使用该软件系统对太原理工大学供水工程实验室数据进行拟合,分析了数据出现误差的原因,对其他同类工程数据的采集和曲线拟合提出建议。供水系统自动化监控系统的研究所涉及的学科较广,对于供水系统自动化监控系统来说,本文以VB为基础,并以SQL Server作为数据库开发了监控系统的运行分析系统,对采集到的数据进行分析研究,以指导供水系统的经济合理运行,这一点是本论文的最大创新所在。供水系统自动化监控系统的研究所涉及的学科较广,对于供水系统自动化监控系统来说,本文以VB为基础开发了监控系统的运行分析系统,对采集到的数据进行分析研究,以指导供水系统的经济合理运行,这一点也是本论文的最大创新。完善自动化监控系统的信息传输与发布功能,实现流域内水信息的互联互通,包括对上游的水雨情采集系统和下游的用水调度系统的互联互通,对于水资源的高效利用,实现从水雨情预报和用水优化调度为一体的计算机自动化监制,有重要的意义。这是下一步研究的重点。
[Abstract]:Computer automation monitoring system is a comprehensive system which combines computer technology, communication technology and control technology. It is widely used in the field of modern industrial control. It has also been used more and more in all kinds of water supply systems in our country. The water supply system can effectively solve the problem of the uneven distribution of water resources in the area of our country, and it can be used for the national people in our country. The economic development is of great significance. In the current water supply system, especially in more and more long distance water supply systems, the number of equipment, the decentralization of the installation position, the high energy consumption, the low operation efficiency, the low management level, the great economic loss after the accident and the efficient and safe operation of the water supply system. The introduction of computer automation monitoring system in the water supply system can carry out remote monitoring and control of the water supply system, manage and control the system effectively, improve the management level, reduce the maintenance cost, and ensure the safe operation of the water supply system.
The automatic monitoring and control system of water supply engineering is complex and involves multidisciplinary. Its design, development and realization is a complex system engineering. Based on the Kingview development platform and the example of Songxi water supply project in Xiyang of Shanxi Province, the development and research of the computer monitoring system of the water supply system are carried out. The main research contents are as follows:
1). The present situation of the industrial field automation monitoring system and the development status and basic structure of the automatic monitoring and control system of water supply system are studied. The advantages of the structure of the hierarchical distributed monitoring system and its application in the water supply system are expounded.
2) analysis the design requirements of Xiyang Songxi water supply engineering automation monitoring system, design the overall plan, compare and analyze the common flowmeter and liquid level meter in principle, choose differential pressure liquid level meter and electromagnetic flowmeter as the hardware equipment of this project, and choose industrial Ethernet to build scheduling center and control sub station. The CPU315-2PN/DN module of SIEMENS is used in the local control unit.
3). Using the Kingview as the software platform, the configuration software is developed according to the system operation requirement. The configuration software is connected to the SQL Server database through ODBC, and the database is written and inquired through the SQL language of the Kingview.
4). Using the VB language as the platform development system operation analysis software, using the measured monitoring data to carry out systematic analysis, fitting the flow head curve, flow efficiency curve and flow power curve of each water pump in Songxi water supply project in Xiyang, and can be adjusted in real time in the monitoring system, so as to provide technical support for the operation of water supply system. The software system is used to fit the data of the water supply Engineering Laboratory of Taiyuan University of Technology, and the reasons for the error of the data are analyzed. Some suggestions for other similar engineering data collection and curve fitting are put forward.
The research of automatic monitoring and control system of water supply system involves a wide range of subjects.
