Design And Realization Of Real-time Image Monitoring System For Dangerous Rock Collapse

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.
