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.
