摘要
在应急救援中,强震发生后的余震、泥石流和滑坡等次生地质灾害将造成进一步的破坏、人员伤亡和财产损失,因此相关的实时灾情信息传递极为重要。针对实时灾情速报中的大地震动分布式测量需求,采用无线网络技术,提出了一种基于置信传播的分布式震动测量机制,设计出了大地震动分布式测量系统。通过仿真对基于信号强度差的置信传播信息融合算法进行了分析验证,结果表明所提算法有效提高了系统性能。
During the emergency rescue process, secondary disasters, such as aftershock, debris flow and landslide, will result in further damage, heavy casualties and property loss after the strong earthquake. Therefore, related real-time disaster information transmission is especially crucial. Aiming at the land vibration distributed measurement demand for real-time disaster reporting, this paper presented a distributed vibration measurement scheme based on belief propagation with wireless networks technology, and designed a distributed measurement system for land vibration. The belief propagation information fusion algorithm were verified based on signal strength difference by simulations. The results show that this algorithm could effectively improve the system performance.
