【摘要】 每年崩塌、滑坡等灾害给世界各国带来巨大的损失,危岩崩塌监测具有重要的现实意义。随着丘陵山地地区公路、栈道等基础设施建设的增多,由于危岩崩塌地质灾害导致的崩塌体公路阻塞、交通长时间拥堵等次生灾害将显著增加,因此加强危岩崩塌监测报警,及时发现危害发生,及时上报有关部门采取相应紧急措施,显得尤为重要。本文针对野外危岩崩塌监测地域存在的供电不足,网络覆盖不足等特殊环境,以图像检测法进行危岩崩塌监测,提出了一种现场采集,现场识别,仅传输预警信息的危岩崩塌实时图像监测系统方案,并自主研发了系统设备。本文主要完成了以下工作:(1)提出了基于图像方式、适用于野外危岩崩塌监测的解决方案,并建立了相应的系统设备框架;(2)提出了以危岩崩塌状态识别以及堆积物大小估测与报警为基础的,基于图像方式、适用于野外危岩崩塌监测的融合算法;(3)设计了数据采集识别设备电路系统,完成基于图像方式的野外危岩崩塌监测融合算法在FPGA上的设计与实现;(4)设计了数据远程传输设备电路系统以及系统设备集成,完成传输设备软件设计;(5)开展了危岩崩塌实时图像监测系统的功能测试与系统指标分析;根据实验测试,所设计的危岩崩塌实时图像监测系统能够实时地对危岩崩塌进行识别和报警,帧率为25fps,检测到现场出现异常后,后台服务器接收到报警信息时间最长约42.7s。更多还原

【Abstract】 Disasters such as rock collapse and landslides bring a huge loss to the world every year,monitoring for dangerous rock collapse has important practical significance.With the increase of infrastructure construction in hilly and mountainous areas,the secondary disasters such as the congestion caused by the geological disasters caused by the collapse of dangerous rock and the long traffic congestion will increase significantly.Therefore,it is necessary to strengthen the dangerous rock collapse monitoring and alarm.It is particularly important to reporting to the relevant departments to take appropriate emergency measures timely.In this paper,in order to monitor in the special environment such as insufficient power supply and lack of network coverage in the field of regional dangerous rock collapse.The method of image detection is used to monitor the dangerous rock.A way of image collection on-site,field identification and transmission of early warning information is proposed to design the real-time image monitoring system.And then complete research and development of the system equipment.This paper mainly completed the following work:(1)Based on the image method,it is suitable for the solution of the wild dangerous rock collapse monitoring,and the corresponding system equipment framework is established.(2)A fusion algorithm based on the image method and the monitoring of the collapse of the dangerous rock is put forward based on the identification of the dangerous rock and the estimation and alarm of the stack size.(3)Design circuit system of the data acquisition and identification equipment,complete the FPGA design and implementation of the image fusion algorithm for the wild dangerous rock collapse monitoring(4)Complete the circuit system design of data remote transmission equipment and system equipment integration,complete software design of the transmission equipment;(5)Carry out function test and system index analysis for the dangerous rock collapse real-time image monitoring system;According to the experimental test,designed real-time image monitoring system for dangerous rock collapse can identify and alarm the dangerous rock collapse in real time.System frame rate is 25 fps.After detecting abnormal on-site,longest time of backend server receives the alarm message is about 42.7 s.更多还原
