From the application and the requirement of earthquake emergency ifeldwork team,a method including composition network,development assistant program and hardware integration is presented in this paper. With this method,the signal from the network of fieldwork team can access the earthquake information network in a safe way. And according to the signal intensity of work site,it helps the non-network professionals to select the optimal network. In addition,this method can provide power endurance support for emergency ifeldwork team.%从地震应急现场工作需求出发,根据组网、编写辅助程序到硬件集成的现场通讯技术,将现场网络接入地震系统内网,并根据实际信号优化工作现场网络,为野外工作提供一定续航能力。
