【摘要】：泥石流监测是泥石流研究的重要组成部分,是研究泥石流形成机理、数学模型的基础,也是解决泥石流预警问题的先行手段。随着科学技术的飞速发展,建立泥石流远程监测系统,通过分析实时数据,提前发布灾害预警信息,能够达到减少人员伤亡和财产损失的目的。本文以泥石流监测作为研究对象,综合应用传感器、无线通信、计算机和信息处理等技术,建立泥石流远程监测系统,克服当前泥石流灾害监测系统存在的不足,提高监测水平。具体研究内容如下:(1)在阅读文献和需求分析的基础上完成了系统方案的设计。通过在监测区域布置网络节点来构建无线传感器网络,利用6Lo WPAN技术实现数据的低功率传输,通过以太网和数传电台等方式实现数据远距离传输。(2)根据泥石流形成的特点提出了一种监测预警算法。结合泥石流地形条件、生态条件、诱发条件等因素,利用D-S证据理论和层次分析法对泥石流的各个指标进行了评价研究,最后通过功效系数法建立泥石流分级预警。(3)利用C#语言设计了泥石流远程监测系统软件。设计了软件的各个功能模块,完成了对数据包的读取、存储工作。设计了人机交互界面,以方便对泥石流的参数进行显示、查询,并可以发布泥石流预警信息。通过实验室调试,监测系统达到了设计的要求,具有一定的实用和推广价值。
[Abstract]:Debris flow monitoring is an important part of debris flow research, is the basis of studying debris flow formation mechanism, mathematical model, and is also a leading means to solve debris flow early warning problem. With the rapid development of science and technology. The remote monitoring system of debris flow can reduce casualties and property losses by analyzing real-time data and issuing disaster warning information in advance. This paper takes debris flow monitoring as the research object. The remote monitoring system of debris flow is established by using sensor, wireless communication, computer and information processing technology to overcome the shortcomings of the current debris flow monitoring system. Improve the monitoring level. The specific research contents are as follows: 1) on the basis of reading the literature and needs analysis, the design of the system scheme is completed. The wireless sensor network is constructed by arranging network nodes in the monitoring area. 6Lo WPAN technology is used to realize low power data transmission. Based on the characteristics of debris flow, a monitoring and early warning algorithm is proposed, which combines the terrain conditions of debris flow and ecological conditions. The D-S evidence theory and analytic hierarchy process (AHP) were used to evaluate each index of debris flow. Finally, through the efficacy coefficient method to establish debris flow classification warning. 3) using C # language to design the remote monitoring system software of debris flow, designed each functional module of the software, completed the data packet reading. The man-machine interface is designed to display and query the parameters of debris flow, and can release the early warning information of debris flow. Through the laboratory debugging, the monitoring system meets the design requirements. It has certain practical and popularizing value.
