There are a lot UAVs can do when disasters happen, such as data collection, communication relay, search and rescue, dispatching command, supplies delivery, etc. With its advantages of big loading capacity and long-distance range, VTOLs are even more common in life search. In addition to the above-mentioned functions of disaster area survey, life search, real-time monitoring, etc., it can also provide accurate rescue, efficient rescue provides strong technical support.In May, 2018, the visual earthquake damage prediction system of xinbeichuan County was launched. Through this system, we can intuitively view how urban buildings shake during the earthquake and which buildings are badly damaged, providing reference for earthquake relief, achieve accurate rescue. This system is seismic resistance and disaster prevention new achievement.
The early data collection work of the visual earthquake damage prediction system is obtained by using the camera of multicolor patchwork carried by the vertical UAV to tilt the Beichuan new county seat. It is understood that the effective area of this aerial survey operation is 6 square kilometers.
According to the different types of each seismic wave, the system can predict the damage degree of urban buildings after the earthquake, thus calculating the key areas of earthquake relief, thus realizing accurate rescue.
Pre-disaster warning, post-disaster rescue and so on all have the active participation of unmanned aerial vehicles. In addition, in the major work of post-disaster reconstruction and hidden danger investigation, unmanned aerial vehicles have the advantages of flexibility and high altitude aerial survey, you can fully understand the progress of post-disaster reconstruction and go deep into places where manual investigation is difficult.
In August, 2017, Jiuzhaigou was hit by an earthquake of magnitude 7.0, which caused damage to many scenic spots in the scenic spot, a large number of landslides, and a large number of geological hazards. Unmanned aerial vehicles carry out aerial survey of scenic spots. Through aerial survey data, we can assist the reconstruction of scenic spots, find geological disaster points that are difficult to be inspected by human beings, promote the risk forecast of geological disasters in scenic spots, and take preventive measures in advance.”
To sum up, vertical UAV plays an increasingly important role and influence in earthquake prevention and disaster reduction. Natural disasters occur frequently in our country, and the losses caused by disasters every year are huge. Improving the early warning ability of earthquake disasters and improving the efficiency and quality of disaster relief are important topics at present. As a supplementary means of satellite remote sensing and manned aerial remote sensing, unmanned aerial vehicle aerial remote sensing system has the advantages of strong real-time, flexibility and convenience, small external environmental impact and low cost, it makes up for the shortcomings of earthquake prevention and disaster reduction work and has broad development space and application prospects.
