Study On Emergency Monitoring Technology Of Landslide Disaster In Highway Region

With the continuous improvement of China’s transportation infrastructure,the mileage of mountain road construction continues to grow,forming a large number of slopes,under the influence of internal and external factors,sudden landslide disasters occur from time to time,in order to ensure highway traffic,and avoid secondary disasters that may occur in disease treatment construction,it is very necessary to carry out highway landslide emergency monitoring technology research.Therefore,this paper proposes an emergency monitoring technology concept based on UAV throwing layout,independent networking of multiple monitoring equipment,and intelligent analysis of slope status,and carries out research on monitoring equipment,UAV throwing control technology,monitoring equipment networking scheme and slope status intelligent analysis algorithm.The main research results and understandings achieved are as follows:(1)Developed slope emergency monitoring equipment based on rapid UAV delivery.Based on the analysis of the performance,function and power consumption of the equipment hardware,the equipment hardware selection requirements are put forward,and the circuit design of each module is carried out;ASTALPSA algorithm is used for scheduling,and the high stability and low-power operation of the device are realized from both software and hardware aspects.According to the soil and rock slopes,the equipment structure of emergency monitoring equipment is designed to improve the environmental adaptability of emergency monitoring equipment.(2)The control technology of UAV delivery monitoring equipment is proposed.The two-dimensional reconstruction of the slope morphology is realized by taking pictures of the slope by UAV.Considering the stability of flight and throwing,a throwing device based on UAV platform was designed.Based on the flight control system of UAV,the method of unmanned flight task and route planning is proposed,and the automatic throwing and deployment of emergency monitoring equipment by UAV is realized.(3)The autonomous networking and coordination technology of bee swarm equipment is proposed.Based on wireless communication technology and sensor network structure,an ad hoc network scheme for emergency monitoring equipment is proposed.The adaptive rate strategy and improved BEB(Binary exponential backoff)binary backoff algorithm are adopted to reduce the influence of device communication crosstalk,improve network fairness and throughput,and provide a stable platform for the communication of emergency monitoring equipment.(4)Developed a highway slope disaster emergency monitoring module.Based on the architecture of the intelligent slope monitoring platform,the emergency monitoring module follows the existing intelligent slope monitoring platform for access,and ensures the safety and reliability of data by designing the database.Aiming at the analysis of monitoring data,an intelligent analysis algorithm of bee colony gridded slope state is proposed,which provides an algorithm basis for slope stability analysis.Through the development of data display modules on PC and mobile,a data display platform was built to provide data support for scientific emergency decision-making on slopes.
