一种便携式消防救援通信箱系统的设计

Design of a Portable Fire Rescue Communication System

在消防应急救援过程中，各种语音通信网络一般各自组网难以实现跨网通信，同时对应急现场和指挥中心的无线视频通信提出需求。结合COFDM无线视频通信技术和网络视频通信技术，利用IP交换机连接无线微波传输模块、异种网络语音互连通讯模块、网络视频传输模块，并放置在一个便携式箱体中，实现了异种网络语音互连以及无线远距离视频通信功能，保障了消防救援现场和指挥中心的音视频通信。

In the fire emergency rescue process, different voice communication networks can only communicate with the same network, and the Wireless video communication between emergency scene and command centre is important. With COFDM wireless video communication technology and network video communication technology ,By using the IP switch with wireless microwave transmission module, heterogeneous network interconnection communication module, audio video network transmis-sion module, and placed in a portable tank, implements heterogeneous network interconnection wireless remote video and voice communication function, safeguard the audio and video communications between the fire rescue site and command center.
