海南省县级山洪监测预警决策支持系统设计和应用

Design and Application of county-level Mountain Torrent Monitoring and Warning Decision Support System in Hainan Province

本文介绍了县级山洪监测预警决策支持系统建设的背景和意义,给出了山洪监测预警决策支持系统的定义,阐述了其设计原则、基于B/S和C/S结合模式以及以B/S模式为主总体的架构设计,可实现以B/S模式山洪监测查询和预警决策支持,以C/S模式对闸门和排水泵监测和控制的独特优点;简要介绍了系统数据库设计;阐述了系统可以表格、画面和GIS电子地图等可视化监测查询信息、以预警响应流程导航实现预警决策支持以及64位DES加密算法应用于系统管理等主要功能;讨论了海南省六县市成功应用以及监测站采用法拉第筒一体化设计。该系统成果可为水情自动测报、水库调度自动化、山洪灾害防治监测及防洪决策等系统研制、设计和实施提供参考借鉴。

The development background and significance for county-level mountain torrent monitoring and warning decision sup-port system are introduced,and the definition of mountain torrent monitoring and warning decision support system is developed in this paper.The design principles,main design structure that is based on combination between the C/S mode and B/S mode and in which the B/S mode is primary,and the unique advantages of county-level mountain torrent monitoring and warning de-cision support system in which mountain torrent monitoring and warning decision support is realized by the B/S mode and com-puter supervisory control of gates and pumps is realized by the C/S mode are explained.The database design of the system is introduced in brief.The main functions of the system in which visual query for monitoring information is realized by forms such as tables,pictures and electronic maps of GIS,in which the warning decision support is realized by the flow navigation of early warning and responding,in which 64-bit DES encrypt arithmetic is adopted in system management are explained.The successful application in 6 counties or cities of Hainan province and integrated design of using the Faraday cup in monitoring stations is discussed.The application the county-level mountain torrent monitoring and warning decision support system in Hainan prov-ince provide a reference for development,design,and implementation of the automation systems,such as auto-monitoring sys-tem of water regime,automation system for reservoir regulation,automation system of monitoring,control and precaution for freshet disaster,and decision-support system for flood control.
