Research On Real-time Monitoring Technology Of BDS/GPS Displacement

Recent years,news of geological disasters was reported frequently,such as landslides,debris flow,ground subsidence,ground fissures,what were caused by many reasons,brought about a great personal and economic losses.There was a common characteristic in these geological disasters,the occurrence of disasters accompanied by the location of the movement,and in the event of instantaneous destruction of roads,bridges,villages,humans have no chance to escape.When repairing the ecological environment,for protecting the human's livelihood,it is necessary to set up an early warning mechanism.Slope instability,landslide occurs usually have a slow displacement process,so we can monitor the slope,through the set of displacement threshold to achieve the monitoring point displacement deformation data real-time warning,and the use of monitoring data Analyze the trend of displacement of the slope as a whole,and use the relevant theory to predict the future data.This early warning mechanism must have the geological disasters have occurred in real-time detection,in case of danger and timely notification of the relevant functions of the staff.In this paper,the BDS / GPS real-time monitoring system,the GPS receiver,sensors and other equipment were used for measuring the data,such as rainfall,acceleration,horizontal and vertical displacement on the landslide,and the displacement Data real-time return,monitoring and forecasting platform for data processing analysis,to confirm whether to reach the warning value,such as has been through the established way to publish early warning information to achieve the purpose of real-time monitoring of landslides.At present,this shift real-time monitoring system can be applied to highway,bridge,mountain and other types of slope monitoring.The BDS / GPS displacement real-time monitoring system includes the modern technology such as BDS / GPS positioning technology,communication technology and sensor technology.The data of horizontal,vertical displacement data,rainfall data and ground stress are acquired.Through the collection of these data,Processing,theestablishment of a set of early warning values,to achieve the establishment of early warning red line,and the establishment of timely monitoring data and broadcast early warning information early warning system.The establishment and application of the BDS / GPS displacement real-time monitoring system improves the safety factor of the facilities such as bridges and slopes,reduces the loss of personal and property,reduces the personnel and financial investment,and with the BDS / GPS displacement monitoring equipment application /GPS related areas of industry development.In the face of geological disasters which seriously endanger the safety of people's life and the people's property,we have long way to go for monitoring and early warning.Researching on Real-time Monitoring System Technology deeply is of great significance to improve slope,bridge real-time monitoring technology.
