The Design and Implementation of a Multi-Source Information Wide Area Adaptive Switching Equipment

摘要

Aiming at the government's demands of extensive social information when organizing disaster rescue and dealing with emergency, a multi-source information wide area adaptive switching equipment was implemented which was highly efficient and multipurpose. The device can provide functions like information format conversion, communicating protocol and physical port adaption, concurrent execution control, and so on. It can solve the problems of collecting and utilizing multisource information, in the domains of message format, communication protocol and port type, and implement the transparent and highly efficient transmission of different kinds of user messages in heterogeneous network environment, meanwhile, in order to collect and utilize all kinds of useful information and message channel extensively. The device can improve the government's command ability to use information-based system, such as emergency mobile command communication system, as well as providing communication technology support.
