This paper presented a method and technology about how to transmit geological disaster data. According to analyzing the NAT devices working principle, the TCP connection was created to stabilize the tuple mapping with the help of public network server, white can realize a P2P communication mechanism to transmit geological disaster data to remote PC directly. After analyzing the deficiencies about TCP protocol, some algorithms were added in application layer to improve TCP protocol in order to improve the communication mechanisms stability. By a great number of tests and practicalities, the mechanism can guarantee the geological disaster datas real-time and reliability which has some practical value to geological disaster monitoring.
This paper proposes an implementation method and technique of Geo-hazards monitoring and early warning system. By analyzing the deficiencies of traditional method about early warning system, we propose a web platform structure based on JSP file to design and achieve an early warning system which integrates real-time data receiving, processing, mapping, managing and automatic alarm .The system uses tomcat as web server, and the platform structure is divided into several modules which are designed as owning scientific and rigorous algorithm respectively. After the actual tests the system not only can display data diversely, but also can send SMS to different people for early warning on different levels according to the changes of the data received by SMS cat. The results prove that the system has good stability, reliability, scalability and maintainability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
