无线局域网在地震应急现场中的应用

Application of wireless local area network in earthquake emergency field work

地震应急是我国防震减灾工作3大体系之一,鉴于地震预报尚不过关,在没有作出临震预报而地震突然发生时,为在灾区进行有效的救援而采取的紧急行动。通信、计算机等新技术是地震应急指挥和救援工作顺利进行的重要保证,无线局域网是计算机网络与无线通信技术相结合的产物,无线局域网利用了无线多址信道的一种有效方法来支持计算机之间的通信,本文根据新疆地震局地震应急现场工作情况,阐述无线局域网在地震应急现场中的应用,讨论了地震应急现场所适应的几种无线局域网的组网模式。

Earthquake emergency is one of three systems of proof-quake and reduce-tragedy in our country. Earthquake emergency is urgency action for effective rescue, which is used without impending forecast. The new technology of communication and computer is important guarantee in earthquake emergency direction and rescuing work. Wireless local area network is outcome of the combination of computer web and wireless communication technology. Wireless local area network supports the communication among computers with the effective way of wireless multiple access channel. In this paper, we illustrate the application of wireless local area network in earthquake emergency field with cases of earthquake emergency work by Earthquake Administration of Xinjiang Uygur Autonomous Region. Several modes for wireless local area network construction are also discussed.
