一种多功能应急广播系统的网关设计
|
摘要
本文针对自然灾害过后的广播需求,提出了一个基于无线网络的多功能应急信息采集与发布系统,此系统不仅实现了广播发布系统功能,并且将语音通话及环境监测功能融合进来,成为一个多功能应急系统。针对此系统,本文使用了嵌入式系统实现了网关部分进行验证,运用shell脚本技术实现对网关的配置管理,讨论了如何将广播及语音通话融合在一起,降低系统的复杂度,并对要实现的环境监测和通信功能进行了模块划分和实现。通过模拟实验场景,对系统功能进行了验证,得出系统从功能上可实现预期目标的结论,并对其中的问题进行了讨论。
Demand for broadcast in the aftermath of natural disasters,a wireless network-based multi-function emergency information collection and release system is putted forward.This system,not only with broadcast publishing system functions,but also with voice calls and the integration of environmental monitoring functions,which become a multi-functional emergency system.For this system, we use the embedded system to achieve the gateway part.The shell script technology is used to the gateway configuration management, how the fusion of broadcasting and voice calls is achieved is also discussed,which will reduce the complexity of the system,and make the module division of the environmental monitoring and communication functions.Through simulation of the scene to the validation of system functions,and one of the issues is also discussed.
