【摘要】：隨著信息化時代的發(fā)展,如何保障河流流域水情信息實時、高效的管理以及危情水情信息實時、準(zhǔn)確的預(yù)警已經(jīng)成為水情信息監(jiān)管工作中重要的研究問題。傳統(tǒng)水情信息存在諸多問題:工作人員需求量大、管理內(nèi)容復(fù)雜、管理標(biāo)準(zhǔn)不規(guī)范、預(yù)警閾值設(shè)置單一、危情警報不夠準(zhǔn)確實時、領(lǐng)導(dǎo)制定方案時無可靠的決策依據(jù)等。本文針對上述問題,設(shè)計了一套河流流域水情信息管理與預(yù)警系統(tǒng)。本文以管理信息系統(tǒng)以及軟件設(shè)計模式的相關(guān)理論為基礎(chǔ),闡述了河流流域水情信息管理與預(yù)警系統(tǒng)的設(shè)計與實現(xiàn)。首先研究相關(guān)技術(shù)及系統(tǒng)發(fā)展的國內(nèi)外現(xiàn)狀,并根據(jù)本系統(tǒng)用戶的實際需求將通用分組無線服務(wù)技術(shù)GPRS、輕量級的數(shù)據(jù)交換格式JSON以及自動計算機輔助設(shè)計軟件AutoCAD應(yīng)用于系統(tǒng)研發(fā)中。其次,詳細(xì)分析了系統(tǒng)業(yè)務(wù)需求,采用模塊化開發(fā)模式將系統(tǒng)分為流域水情信息管理和流域水情預(yù)警兩個子系統(tǒng)。流域信息管理子系統(tǒng)采用C/S設(shè)計模式,主要包括水情信息獲取、水情信息管理、用戶管理、系統(tǒng)管理與流域文件、記錄管理、決策依據(jù)生成等;預(yù)警子系統(tǒng)中,通過研究GPRS通信機制以及分析其時延性確定系統(tǒng)通信模式,完成預(yù)警信息匯集、閾值設(shè)置、短信預(yù)警等功能;通過類圖設(shè)計出各個子系統(tǒng)中各模塊的靜態(tài)模型,通過時序圖、協(xié)作圖以及流程圖設(shè)計出各模塊的動態(tài)模型。然后,根據(jù)目前預(yù)警系統(tǒng)中實時性、準(zhǔn)確性的不足,對預(yù)警子系統(tǒng)中短信預(yù)警做出詳細(xì)參數(shù)描述,設(shè)計預(yù)警內(nèi)容格式,并且對單個節(jié)點預(yù)警和批量節(jié)點預(yù)警做了論述。最后,論述了系統(tǒng)的實現(xiàn)。本系統(tǒng)已應(yīng)用于實際項目。系統(tǒng)從功能和性能兩方面進(jìn)行測試,測試結(jié)果表明系統(tǒng)可以快速、高效的做出危險水情處理方案,并可以基于各個模塊的實現(xiàn)、關(guān)鍵技術(shù)的應(yīng)用生成一份詳實可靠的決策報告提供給水利局工作人員。
[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.
