【摘要】 强烈地震发生后,灾区现场通信网络设施往往遭到破坏,因此快速建立有效且覆盖面大的应急通信网络,及时传递灾情信息,对现场组织救灾及指挥调度等救援工作具有重大意义。无线网络具有组网简单快速、成本低等技术特点,适合作为现场应急通信的网络平台。本文提出了一种基于无线Mesh网络技术的地震现场应急通信方法,在灾区现场迅速组建无线局域网,从而实现信息传递和共享,整个系统组网快捷、健壮性好,并且通过卫星通信技术可以将各局域网组成灾区广域网并进一步接入互联网,该方法能满足地震现场应急通信信息传输的基本要求。更多还原

【Abstract】 After strong earthquake,the local field communication network facilities are often damaged,so quickly establish effective emergency communication network coverage,delivering timely disaster information is of great significance for the rescue work such as disaster relief organization and command scheduling,etc.Wireless networks because of its technical characteristics,such as simple,rapid,low cost,are very suitable as the platform of on-site emergency communication network.This paper puts forward a method for earthquake field emergency communication based on wireless Mesh network,that is using wireless Mesh network technology rapidly to form a wireless LAN at the scene of the disaster area,so as to realize information transfer and sharing in the disaster zone.The whole system network is fast and good robustness.With using satellite communication technology,all of local area network can be composed of a wide area network,and access to the Internet.This method can meet the basic requirements for information transmission of the emergency scene.更多还原
