Design and Implementation of Emergency Command and Communication System in"Three Breaks"Environment
In recent years,with the frequent occurrence of natural disasters,the technical require-ments of emergency command and communication have been continuously improved,especially in the case of power interruption,road interruption and communication interruption.Therefore,the design and implementation of emergency command and communication system in the"three interruptions"environment are proposed.Through the design of emergency command commu-nication terminal and emergency command dispatcher,the hardware design of the system is com-pleted.In the software design of the system,the bandwidth of communication information transmission is calculated by using the interference index of communication information trans-mission channel,and the total load of the system when transmitting emergency command com-munication information is calculated by determining the queue length of communication infor-mation transmission nodes,thus realizing emergency command communication in the"three outages"environment.The system test results show that the moving distance of sensor nodes and the sensing radius of sensors have little influence on the system in this paper,and the communi-cation efficiency is high.
