【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]:As an effective means of geological hazard monitoring and early warning, group monitoring group prevention has been paid more and more attention. In view of the disadvantages of monitoring information in our country's geological hazard group monitoring and prevention work, such as the failure to transmit the monitoring information step by step in time and the information "distortion" and so on. This paper puts forward a design method and realization technology of geological disaster group detection and monitoring system based on smart phone. This paper analyzes the conditions of two-way communication between Socket wireless communication API of Android system and different internal network nodes, designs the software architecture of group test group prevention terminal based on smart phone, adopts GPRS wireless communication technology, and takes the public network server as the information forwarding terminal. The information forwarding mechanism based on TCP protocol is designed, and the three-level communication of "smart phone terminal-public network server-intranet PC" is realized, which ensures the security and stability of monitoring information. At the same time, for communication process control, a good communication mechanism and data encapsulation mechanism are designed in the application layer, which can greatly reduce the amount of data transmission and data transmission time, and improve the communication efficiency. The practical application shows that no matter the GPRS mobile communication or the VPN network communication, the system can realize the convenient input and efficient and stable transmission of the geological hazard group survey and prevention information.
