为提高应对突发事件的能力,安徽省电力公司建设了基于4G通信技术的应急通信系统。提出了3G公网,微波自组网多种通信模式互补通信的方案,实现应急区域无盲区覆盖;设计开发了基于IP软交换技术及DSP信号处理技术的多种语音网络互连模块,可以将不同类型的语音通信终端融合起来,实现互连互通,在视频传输方面,利用微波通信技术,解决了公网中断的应急情况下语音视频的实时传输。为应急救援人员提供了新的通信手段。
In order to improve the ability to deal with emergencies, Anhui Provincial Electric Power Company has built an emergency communication system based on 4G communication technology. Proposed 3G public network, microwave ad hoc network a variety of communication modes of complementary communication program to achieve emergency area without blind area coverage; design and development of IP softswitch technology and DSP signal processing based on a variety of voice network interconnection module, you can Different types of voice communication terminals are merged to realize interconnection and intercommunication. In the aspect of video transmission, microwave communication technology is used to solve the real-time transmission of voice and video in the case of public network interruption. Emergency rescue workers provided a new means of communication.
