Research Of The Monitoring System Of The Abandoned Mine Landfill Slope Based On Wireless Sensor Network Technology

In order to solve Garbage Around City and the comprehensive management of abandoned mine problems, the abandoned mine as a landfill is a way to solve both problems simultaneously effective way. However, due to the instability of abandoned mine’s high and steep slope, In use process, it’s likely to occur landslide hazard. So we need a effective monitoring way to monitor and predict the slope stability.This paper use GPS receiving cell and wireless sensor network as the core of the monitoring system, we’ll design a fixed device in the monitoring stations, verify the stability of the device in using ANSYS analysis when it subject to large external force. According to the characteristics of wireless sensor network data transmission, we build a network model to analysis the network data transmission’s energy consumption, obtained the minimum energy loss data transmission strategy under the conditions of the energy balance.At the same time, conducting on-site simulator experiments in use of the GPS receiver and unit ZigBee development kit whose core is CC2530. We’ll monitor the lope landslide displacement at different soil moisture conditions, and transport monitoring data to the computer, then using MATLAB data to conduct the fitting calculation, finally get the regular pattern between the soil moisture content and landslide displacement, and verify the effectiveness of the system.Finally, We use the Kalman filter which’s based on global information for calculating the monitoring of the integration of GPS data, and compare integration of results with the measured values, verify the fusion algorithm can accurately predict the trend of slope displacement, and increase the accuracy of prediction.
