【摘要】 目前,国家水利部门为了提升灌区量水信息的监测能力,以适应我国农业灌溉用水不断扩大的需求,各灌区水利部门已经开始采用基于B/S或者C/S的量水无线自动采集软件来对各个灌溉区域监测点进行数据的采集及辅助管理。基于B/S模式监测系统的优势在于能够实现系统维护和管理、操作简单以及数据信息共享性较强,并可使分散较广的监测站点实现数据的共享浏览。但是,基于这种模式开发的系统扩展能力差,难以实现系统与传感器及通讯模块之间的信息传递；另外,系统稳定性及数据处理能力较差,难以实现对数据的有效处理和利用。基于C/S模式监测系统的优势在于能够实现快速的系统响应、通讯功能较强、全面的数据处理,以及可以在局域网内部实现数据共享和数据高效利用。然而,这种模式开发的系统灵活性较差,难以实现外部站点对数据的浏览请求,而且安装、维护、调试等较为麻烦,成本较高。由此看来,如何根据B/S和C/S这两种模式的特点,集成这两种模式运用于新的监测系统。采用B/S和C/S的集成模型开发的监测系统可以使系统与采集模块之间进行无线通信,实现量水数据的无线采集以及存储,为水利部门及灌区用户提供了数据支持,并运用可视化图表等对数据进行相关处理,为其用水调度和合理灌溉提供决策支持。针对灌区监测点当前的环境特点及用户和管理者的需求,作者以GPRS无线通信技术及B/S和C/S两种软件开发模式为理论支持,利用Delphi7、ASP.Net开发平台和Office Access数据库平台为技术基础,研究并开发了基于B/S和C/S集成模型的灌区量水监测系统,实现了量水信息的自动触发采集、基于B/S的外部数据浏览、基于C/S的低功耗数据采集,并对采集数据进行可视化处理,最终为管理部门提供决策支持。作者在论文中主要从以下方面进行了详细的研究：1.对无线传输技术进行了深入的研究,详细分析了灌区数据采集传输的特点,介绍了在传统的光纤传输、电台传输中存在着应用成本较高、数据精度较低的问题,并提出采用GPRS作为无线采集的数据传输方法来解决以上问题。2.详细分析B/S和C/S两种软件开发模式,结合两种模式的优点,提出了B/S和C/S集成模型的软件开发新模式。3.分析了该系统的整体架构,以模块化设计理念为基础进行了该系统功能划分。4.研究基于B/S和C/S集成模型的灌区量水监测系统的软件结构及其各子系统的功能和组成,并通过编程语言实现系统的功能；经过运行测试表明,该系统B/S和C/S的数据浏览模式稳定、可靠,间隔的数据采集方式省电、成本低。更多还原

【Abstract】 At present, in order to improve irrigation information monitoring capacity to meet the growing demand for the irrigation, the national water sector has collected and managed the data automatically at irrigation monitoring points based on B/S or C/S model by means of the wireless software. The system based on B/S model has the advantages of easy maintenance, convenient management and sharing information which can be time-scanned at every irrigation monitoring point. However, the expansion capacity of the system based on this model is very poor and it is difficult to transmit information between the sensors and communication modules in the system. In addition, the stability and data processing capability of the system is also poor and the system data can not be processed and utilized efficiently. The advantage of the system based on C/S model is rapid response, strong communication, and comprehensive data processing, data sharing and efficient application within the LAN. But the flexibility of the system adopted this model is very poor, and it is difficult for users to get data browsing request from external sites. And its installation, maintenance and test are more cumbersome, and its cost of the operations is very high.In this case, it is the key technology to integrate the models of B/S and C/S for the monitoring system. Wireless communications between the system and acquisition modules can be realized, its data collection and storage can be realized too. Moreover, these visual diagrams and charts can be used to support reasonable decision for irrigation water sector. In order to satisfy the requests of users and current environment, the author provides the water monitoring system for the irrigation based on the integrated modes of B/S and C/S with GPRS wireless and other communication technologies. By means of Delphi7, ASP.Net development platform and Office Access database platform, automatic information collection, external scanning, visual data management and low-power data acquisition can be realized in this system. It can be used to support reasonable decision for irrigation water sector.The main works done by the author include following items:1. Wireless transmission technology is studied, and the transmission characteristics of irrigated area are analyzed. The problems (i.e. high cost and low precision) existed in the traditional optical fiber transmission and radio transmission are presented. To apply GPRS for data transmission, above problems can be solved effectively.2. Software developing systems based on the B/S and C/S model are analyzed, and combining their advantages, the integrated model is proposed.3. Whole architecture of the system is analyzed, and then according to modular. design concept, the function modes of the system are divided.4. Based on the integrated models of B/S and C/S, the software architecture of the irrigation district water monitoring system is studied, the functions and compositions of its subsystems are analyzed, and these functions are realized by programming language. The testing results show that the data browsing mode in the system of B/S and C/S is stable and reliable; the interval method of data collection can be used with save power and low cost.更多还原
