The Research Of Emergency Communication System Based On Hybrid Communication

In this thesis, we design a hybrid communication gateway based on emergency communication. According to the above requirements, it is necessary to introduce ZigBee module, WIFI module and 3G module to form wireless communication network in the specially region. The whole system includes the design of the covering algorithm, the hardware system,the software system and the front display system. It consists of four parts.In this paper, referring to the existing background of the gateway design,in the basic design ideas on the integration of a number of other technologies, the old program in the design provides innovative ideas. On the topology, all modules are grid, set the edge and the convergence node and the core node. Edge nodes connect sensor devices to collect data. The main routing strategy to the core node. Reference maze algorithm for routing rules.In the communication gateway, Boost network is used to communicate with TCP network and Websocket network, and the data acquisition system, data forwarding system and Web server are designed.Join data threshold analysis, frequency analysis, equipment fault detection and filtering strategy data noise data acquisition system. The data forwarding system defines the appropriate communication protocol, tihe integration strategy and the choice of the network strategy. The Web server receives the data information transmitted by the core node to the outside.Waiting for the user to establish a long connection, the delivery of disaster,instead of the development of client applications.
