摘要
本论文以山西省阳泉市桃河治理工程自动化监控系统为研究背景,具体涉及到水利信息化和充水泵站监控自动化系统开发研究的相关内容。本文综述了水利信息化的基本概念、发展状况和监控系统发展的状况,具体对集中式监控系统、集散式监控系统(DCS)、现场总线监控系统(FCS)的优缺点及监控系统的日后发展方向进行了简介。经过对多种监控系统方式的比较和从工程的具体实际情况出发,在该系统开发研究中采用了集散式监控系统(分层分布式控制系统),以局域网的形式把各测控站、分中心站经光纤链路组成网络;并开发研究了相应的监控系统软件。整个系统本着标准化、实时性、开放性、实用性、可靠性、稳定性、安全性等原则而完成。开发研究的具体内容包括:充水泵站监控系统的集成、系统功能的实现;信号采集与处理、通讯方式的选取;硬件选型以及组态软件的编制;系统可靠性分析研究等。在硬件选型方面,严格按照先进性、可靠性、开放性、性价比高、扩展和升级功能好等要求来进行选取。在软件开发方面,采用了具有接口开放、实时多任务、可靠性高等特点的北京亚控公司生产的KINGVIEW6.03作为后台实时监控程序设计工具,而前端组态软件程序设计采用了由西门子公司生产的具有组态灵活、指令丰富、含有多种智能模块和复杂数学运算等特点的SIMATIC S7-200用户程序作为开发工具。开发出来的软件运行界面友好,图形丰富直观,仿真效果好,对设备控制方便。
整个系统实现了数据采集功能、泵站自动控制功能、连锁与报警功能、过程参数就地数字显示功能、电机软启动功能,监控功能达到了“一次成功,用户放心”的目的。系统的实际运行表明PLC的I/O配置灵活、扩充方便、编程简单;利用组态王进行应用程序设计,设计周期短,图形界面丰富,实时多任务,接口开放,使用灵活,功能多样,运行可靠;充水泵站系统实现自动化监测,有益于供水系统的节能、提高系统的运行效率及水资源的合理调度。关键设备和中间件都采用冗余设置,同时采用软件冗余设计技术来提高系统的可靠性,并采取一些必要保护措施如接地、避雷装置等来预防雷电、噪音信号窜入设备,影响系统运行的稳定性和安全性。整个系统的开发研究和功能实现完全满足水利信息化的发展要求,该系统的集成是技术进步的产物,是在水利信息化的呼唤下应运而生。
目前该系统按照本研究开发的方案已经建设完成,可以预期系统的安全、经济运行将会产生良好的经济和社会效益。
当然,自动化系统经济效益的体现,还需要良好的售后服务及加强系统现场操作人员的培训才可能实现,这一点,需要工程管理单位务必有清醒的认识。
The paper is based on the Automatic Monitored Control System of LINF TAOhe Integrated Modification Project, specific related to the content of the engineering information and the monitor automation of pumping station system’s development and study. It comprehensively discusses the elementary concept and the development status of the hydraulic information and the development status of the monitor control system. At the same time, it specific introduces the merits and drawbacks of the centralization monitor control system, the distributor monitor control system and the fieldbus control system, and the trend of development of the monitor control system of the future. The system adopts the DCS (the distributor monitor control system) through the comparison of some kinds fashion of monitor control system and the considerations of the project’s reality conditions, and assume the LAN way to take every measure control station and low junction center through fibre-optic transmission system to become a networks; And have studied and developed the corresponding monitor system software.
The total system is finished according to the principle that is standardization, real-time, openness, practicability, reliability, stability and security. The study and development content mainly include the integration of pumping station monitor control system,how to realize the system’s function; acquisition and treating signal, the selecting of communication fashion; the lectotype of hardware and the program composition of the configuration software; the study and analysis of the system’s reliability and so on. On the way of the lectotype of hardware, it is accessed by these demands that are advanced, reliability, openness, cost performance is high, and the function of stage and expansion is good and so on. On the way of system software development, the KINGVIEW6.03 is used for the design tool of background real-time monitor control program, produced by the BeiJing YaKong Company. SIMATIC S7-200 user program is used for the development tool of the foreground configuration software program design, produced by the Siemens Company; it is of these features that configuration flexible, instruction enrichment, mathematical manipulation and some other intelligence module communication instruction and so on. The developed software that the working procedure interface is friendly, the graph is abundantly and intuition, the emulation effectiveness is good and can control the facility conveniently.
The total system achieves those functions that is data collection, pumping station autocontrol, catenation and alarm,procedure parameter on site display the number,electric engine gently start-up,monitor function etc. ,attaining the target of“once come through, user set their heart at rest”. The practice operation of the system shows that the PLC is configuration agility, extension conveniently, programming simply; adopting configuration king carrying through the design of application program that is the design cycle short, graphical interfaces abundantly, real-time and multitask, the interface opening, using agility, function multiplicity, operation credibility; realizing the automation monitoring of the supply-water pumping station system that is effective of energy-saving for the supply-water system, increasing of running efficiency of the system, and make the water resources dispatched rationally. The system adopts redundance settings in all the key equipment and the midst piece, at the same time adopts software redundance design technology to enhance the system’s reliability, on the moreover, there takes some necessary safeguards such as the ground protection installation, the lightning conductor and so on to prevent the thunderbolt, the noises signal into the equipment, changing the operation stability and security of the system. The development and study and the achieving function of the whole system satisfy the development demand of the hydraulic information, the integration of this system is the production of the era’s developing, and emerges as the times require under the water conservancy information calling.
At the present time this system has been constructed and accomplished, the safety and economy operation of system will bring good economy benefit and society benefit.
Of course,the economy efficiency of automatic system’s externalization that still need well service after sale and strengthen train of the site operating staff of the system can realize, therefore, it require the unit of project management that must to have lucidum cognition.
