基于4G的应急通信在安徽电力的应用

Application of 4G-based Emergency Communication System in Anhui Electric Power Communication

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 in responding to emergent hazards, Anhui Electric Power Company establishes an emergency communication system based on 4G communication technology. Multiple communication modes are proposed, including 3G public network and microwave self-organized network, thus to realize no-blind-area coverage in emergency zone. Meanwhile, a variety of voice network interconnection modules based on IP soft switch technology and DSP signal processing technology are designed, and the network communication problems in complex environment solved. Thus different types of speech communication terminal are integrated to achieve inter connectivity; while in video transmission, microwave communication technology is utilized to achieve real-time speech and video transmission when the public network breaks off. The system could provide a new communication means for emergency rescue personnel.
