    DEVELOPMENT OF SMARTPHONE BASED GEOHAZARDS MITIGATION TERMINALS FOR DERSTANDING AND MONITORING OF RESIDENTS AT VAST RURAL AREAS

    • 摘要: 群测群防作为一种有效的地质灾害监测预警手段愈发受到重视,针对目前我国地质灾害群测群防工作存在的监测信息逐级传递不及时、信息失真等弊端,提出了一种基于智能手机的地质灾害群测群防监测系统的设计方法及实现技术。分析了Android系统的Socket无线通信API和位于不同内网节点进行双向通信的条件,设计了基于智能手机的群测群防终端软件架构,采用GPRS无线通信技术,以公网服务器作为信息转发端,设计了基于TCP协议的信息转发机制,实现了智能手机终端-公网服务器-内网PC(监测平台)的3级通信,保证了监测信息的安全性和稳定性。同时对于通信过程控制,在应用层设计了良好的通信机制和数据封装机制,能够大大减少数据传输量和数据传输时间,提高通信效率。实际应用表明:无论是GPRS移动通信还是VPN网络通信,系统能够实现地质灾害群测群防信息的便捷录入与高效稳定传输。

       

      Abstract: The method of residents' self-mitigating of disasters is a basic form to control geohazards in the vast rural areas of China. At present,we always transfer the monitoring information with the method of step by step. Such information transfer is not in a timely manner. The experts may not get the first-hand data about the geohazards. So this paper proposes a design method and realization technology about the geohazards monitoring and early warning system by local people at rural areas. It analyzes the Android's Socket API technique and the communication conditions among the different internal network nodes. Then it designs the application software structure of the monitoring terminal based on smartphones in order to record the geohazards information. The system is supported by the public network server. It is designed a forwarding information mechanism based on TCP to realize the communication among the mobile phone,public network server and internal monitoring platform. It forwards the monitoring information with GPRS or VPN(Virtual Private Network).100mobile terminals are arranged in Guizhou Province. The results of actual application indicate that the system can conveniently transmit the geohazards information with the characteristics of security,efficiency and stability,which meets the actual requirements.
