摘要
针对目前突发事件的应急通信设备存在的设备笨重、系统集成度不高、无法手持、视频传输能力弱等问题,提出了一种基于Ad-hoc网络的手持式应急通信设备的设计方案。采用TMS320DM365控制芯片和无线通信模块为硬件平台开发平台,以嵌入式Linux为系统软件平台。系统研究了达芬奇技术传输视频原理,并针对手持式应急通信设备节能要求,采用一种改进后节能的AODV路由算法。该设备具有能传输视频、便携式、节能等特点。通过搭建平台对设备进行测试,证明该设计可行性。
View of the current emergency communication device there are some problems such as equipment heavy, not high degree of system integration, not hand-held, weak of video transmission and so on. A program of the design of hand-held emergency communication device based on ad-hoc network is proposed. The program uses the TMS320DM365 microprocessor and wireless transmission module as hardware development, platform, embed- ded linux as a system software platform. Based on the study of the Davinci video transmission, aim at the energy saving demand of hand-held emergency communication device, a improved protocol of AODV （ Ad-hoc On Demand Distance Vector） is adopted. The system is simple, with a high performance, small size, micro-power, portable and so on. Finally, the design feasibility is verified by testing the device on a constructing platform.
