便携式应急通信终端设计

Design of Portable Emergency Communication Terminal

该文在研究了北斗卫星导航系统短报文功能的基础上,针对移动网络和短波通信不畅,甚至无网络条件下,人员位置、现场状态等信息,无法进行获取的问题。提出了一种基于北斗短报文的便携终端的设计方案,适用于无移动网络信号条件下的定位和应急通讯,具有十分重要的应用价值。

Based on the study of short message function of Beidou satellite-navigation system,for mobile networks and shortwave poor communication problems,even in the absence of network conditions,personnel location,field status and other information can not be obtained.Puts forward a design scheme of portable terminal based on Beidou short message,which is suitable for positioning and emergency communication under the condition of no mobile network signal,and has very important application value.
