基于WebGIS的古建筑损坏自动报警系统的设计与实现

Design and implementation of WebGIS-based automatic alarm system for ancient buildings′ damage

古建筑作为不可再生资源,损坏防范难度较高。因此,提出一种基于WebGIS的古建筑损坏自动报警系统,该系统包括古建筑损坏监测系统、监测预警平台和古建筑损坏监测预警系统、信息传输通信网等部分。古建筑损坏监测系统依靠地理信息系统(GIS),对雨量、水位、气候等损坏古建筑的客观因素进行监测。通过信息传输通信网,将古建筑损坏信息传入监测预警平台,实现信息交互共享。监测预警平台对数据进行操作,并将数据存入信息汇集系统。信息汇集系统对古建筑损坏实时情况进行查询,将互联网与古建筑损坏检测信息相结合,提高古建筑损坏预警的时效性,并给出信息汇集系统的关键代码设计。实验结果表明,提出的方法对于古建筑损坏的预警实用性高,具有较高的自动报警准确率。

As the ancient buildings are non?renewable resources and difficult to prevent damage to them,a WebGIS?basedautomatic alarm system for the ancient buildings’damage is put forward. The system is composed of monitoring subsystem,mon?itoring and early warning subsystem,information transmission network for ancient buildings damage,etc. The geographic infor?mation system(GIS)is used in this system to monitor rainfall,water level,climate and other objective factors’damage to theancient buildings. The information transmission network is applied to transmission of the ancient buildings’damage informationto the monitoring and early warning platform to realize information interaction and sharing,and to the data processing and the da?ta storage into information collection subsystem. The subsystem conducts the real?time query of ancient building damage situa?tion. The system combines Internet with the ancient building damage detection information to improve the effectiveness of earlywarning of ancient buildings’damage. The design process of key code of information collection subsystem is given in this paper.The experiment results show that the proposed method has high practicability of early warning for ancient buildings’damage,and high accuracy rate of automatic alarm.
