【摘要】 水利是我国国民经济的命脉,是社会稳定之根本。发展水利自动化监控系统建设是体现人水和谐,实现科学治水、节约用水的必由之路。目前我国水利自动化监控系统的通信方式基本全部采用通信光缆、信号线等有线通信方式。有线通信方式由于其本身具有建设周期长、投资大、扩展性差和维护性差等弊端,很大程度上导致我国水利自动化监控系统至今无法实现全国、甚至地区性组网。而无线通信技术具有建设周期短、投资少、扩展性强和维护简单的诸多优点。因此,本文研究如何将无线通信技术与有线通信技术相结合,将无线通信技术的各项优势更好、更全面的在水利自动化监控系统中得到应用,而且本文重点描述了ZigBee和Wi-Fi局域无线通信技术在水利自动化监控系统中的应用,这些研究在当前国内水利自动化领域中具有创新性。首先,本文将无线通信方式与有线通信方式进行客观比较,得出无线通信方式的优缺点。其次,通过描述本人在实际工作中设计实施的两个工程案例,分别阐述了无线通信技术是有线通信技术的补充与完善的观点；以及如何将局域无线通信技术和广域无线通信技术相融合的方式与方法。在两个案例说明的过程中,本文采用图表等多种形式重点对如何搭建以GPRS无线广域网、ZigBee或Wi-Fi无线局域网和有线通信网络相结合的通信网络的硬件结构做了详细描述,接着对两个案例系统的软件结构进行了简单介绍。通过对比和举例等方法,本人提出：只有建设“有线与无线通信技术相结合,广域无线与局域无线网络相融合”的新型水利自动化监控系统发展模式,才能全面、高效的搭建区域性乃至全国性的水利自动化监控系统。所以,采用无线通信技术尤其是以ZigBee和Wi-Fi为代表的新兴局域无线通信技术是全面实现水利自动化与信息化的必然选择。最后,本文对未来水利自动化监控系统的发展趋势进行总结与展望。更多还原

【Abstract】 Water resources in China are the lifeblood of the national economy and the root of social stability. It is the only way to build the hydraulic automatic supervisory control system in order to show the harmony between the human and water and achieve water conservancy in scientific way and water saving. At present most of communication modes of our hydraulic automatic supervisory control system use wire communication such as communication cables, signal lines, etc. With wire communication mode which has a long construction period, large investment, poor expansibility and maintainability, our hydraulic automatic supervisory control system has been unable to realize the national or even regional network. However, wireless communication technology has a short construction period, less investment, strong expansibility and easy maintenance, etc. Therefore, this paper will study how to fuse wireless communication technology with wire communication technology, and apply the technology of wireless communication to the hydraulic automatic supervisory control system better and more comprehensively. Besides, this paper focuses on the ZigBee and Wi-Fi local wireless communication technology applied in hydraulic automatic supervisory control system. All these studies above are innovative in the current domestic hydraulic automation field.First of all, this paper. concludes both advantages and disadvantages of wireless communication by means of comparing wire with wireless communication.Secondly, through the description of two engineering cases designed and implemented in my past work, I elaborate that wireless communication technology is the supplement and consummation of wire communication technology, and how to fuse the local wireless communication technology with the wide wireless communication technology. In the two cases, this paper describes in detail how to build the hardware structure of communication network fusing GPRS, ZigBee or Wi-Fi local wireless network with wire communication network with graphs and other forms. Then the software structure of these two cases is introduced simply. Then through the comparison and example methods, I put forward that it is the only way to develop the new mode of hydraulic automatic supervisory control system which fuses wire with wireless communication, and wide with local wireless to build regional and even national hydraulic automatic supervisory control system comprehensively and efficiently. Therefore, it is inevitable to apply wireless communication technology especially the new local wireless communication technology with ZigBee and Wi-Fi as the representative to comprehensively realize hydraulic automation and infomationization.At last, besides the summarization of the whole paper, it draws a blueprint of hydraulic automatic supervisory control system in future.更多还原
