Research and realization of wireless metropolitan area network for surveillance based on WebGIS

为了实现无线城域网监控(WMAnS)的透明化、可视化与实时互动化,研究了无线城域网监控系统的系统架构和功能,着重分析了系统实现的关键问题以及网络地理信息系统(WEbgIS)在系统的核心功能。再运用软件工程领域成熟的统一建模语言(uMl)设计系统软件模型,最后通过无线城域网传输gPS信息、语音和视频等数据,运用开源网络地理信息系统工程MAPguIdE OPEnSOurCE实现终端监控、终端调度、信息发布等功能。In order to establish a transparent, visible, real-time, and interactive wireless metropolitan area network for surveillance (WManS), the architecture and functionality of the system are studied at first.The key implementation issues and the core functions of WebGIS are then specially focused.The unified modeling language (UML) is utilized to design the system software model.By adopting the open source tool MapGuide Opensource, the GPS messages, audio, and video data are transmitted via wireless metropolitan area network.Finally, the system functions are implemented including monitoring, scheduling, and message distributing, etc.国家863高技术研究发展计划基金项目(2007AA01Z289);国家973重点基础研究发展计划基金项目(2007CB310608

Study on Architecture and Unified Model of Urban Emergency Response System

根据我国对城市应急联动系统(uErS)建设的要求,遵循软件工程领域内成熟的模型语言规范,设计一个基于统一建模语言的uErS模型,包括决策指挥中心、应急联动中心、各联动单位的调度中心、联动单位的分支机构、处置力量部门和处置力量编组。该模型可以协助系统开发人员规范系统的开发与软件重用,优化系统结构,加快uErS的开发进度。In order to meet the development demand of Urban Emergency Response System(UERS) in China,this paper designs a UERS model based on Unified Model Language(UML),which follows the mature modeling language standard of software engineering.The UERS model includes a decision-making of emergency command center,an emergency responding coordination center,dispatching centers of all cooperative units,the sub-branches of the cooperative units,execution divisions and sub-divisions.It can assist the system developers to regulate the development and software reusability of the system,optimize the system architecture,and accelerate the development of UERS.贵州省科技厅基金资助项目(黔科合软.R字(2007)2004号
