【摘要】：随着信息化时代的发展,如何保障河流流域水情信息实时、高效的管理以及危情水情信息实时、准确的预警已经成为水情信息监管工作中重要的研究问题。传统水情信息存在诸多问题:工作人员需求量大、管理内容复杂、管理标准不规范、预警阈值设置单一、危情警报不够准确实时、领导制定方案时无可靠的决策依据等。本文针对上述问题,设计了一套河流流域水情信息管理与预警系统。本文以管理信息系统以及软件设计模式的相关理论为基础,阐述了河流流域水情信息管理与预警系统的设计与实现。首先研究相关技术及系统发展的国内外现状,并根据本系统用户的实际需求将通用分组无线服务技术GPRS、轻量级的数据交换格式JSON以及自动计算机辅助设计软件AutoCAD应用于系统研发中。其次,详细分析了系统业务需求,采用模块化开发模式将系统分为流域水情信息管理和流域水情预警两个子系统。流域信息管理子系统采用C/S设计模式,主要包括水情信息获取、水情信息管理、用户管理、系统管理与流域文件、记录管理、决策依据生成等;预警子系统中,通过研究GPRS通信机制以及分析其时延性确定系统通信模式,完成预警信息汇集、阈值设置、短信预警等功能;通过类图设计出各个子系统中各模块的静态模型,通过时序图、协作图以及流程图设计出各模块的动态模型。然后,根据目前预警系统中实时性、准确性的不足,对预警子系统中短信预警做出详细参数描述,设计预警内容格式,并且对单个节点预警和批量节点预警做了论述。最后,论述了系统的实现。本系统已应用于实际项目。系统从功能和性能两方面进行测试,测试结果表明系统可以快速、高效的做出危险水情处理方案,并可以基于各个模块的实现、关键技术的应用生成一份详实可靠的决策报告提供给水利局工作人员。
[Abstract]:With the development of information age, how to ensure the real-time of river basin hydrological information, efficient management and real-time information of dangerous water regime, accurate early warning has become an important research problem in the supervision of hydrological information. There are many problems in traditional hydrologic information, such as large demand for staff, complicated management content, non-standard management standard, single warning threshold, inaccurate and real-time warning, and no reliable decision basis when leaders make plans. In order to solve the above problems, a set of river basin hydrological information management and early warning system is designed in this paper. Based on the theory of management information system and software design pattern, the design and implementation of river basin water regime information management and early warning system are described in this paper. First of all, the domestic and foreign current situation of related technology and system development is studied. According to the actual needs of the users of the system, the lightweight data exchange format (JSON) of general packet radio service technology (GPRS,) and the automatic computer-aided design software (AutoCAD) are applied to the system development. Secondly, the business requirements of the system are analyzed in detail, and the system is divided into two subsystems: watershed water regime information management and watershed water regime warning. The watershed information management subsystem adopts the C / S design pattern, which mainly includes water regime information acquisition, water regime information management, user management, system management and watershed files, record management, decision basis generation, etc. By studying the communication mechanism of GPRS and analyzing the time ductility to determine the communication mode of the system, the functions of gathering early warning information, setting threshold, short message warning and so on are completed; the static model of each module in each subsystem is designed by class diagram, and the static model of each module is designed by timing diagram. The dynamic model of each module is designed by collaboration diagram and flow chart. Then, according to the deficiency of real-time and accuracy in the current early warning system, the detailed parameter description of short message early warning in early warning subsystem, the design of early warning content format, and the discussion of single node early warning and batch node early warning are given. Finally, the realization of the system is discussed. The system has been applied to practical projects. The test results show that the system can quickly and efficiently make the solution of dangerous water regime, and it can be implemented based on each module. The application of key technologies generates a detailed and reliable decision-making report to the staff of the Water Conservancy Bureau.
