| Abstract: | The Beidou satellite navigation system is briefly introduced,and the Beidou cloud monitoring system suitable for slope deformation monitoring is established based on the Beidou satellite navigation and positioning system.The system mainly includes four parts:data acquisition,data transmission,data analysis and result display,which realizes the whole process automation from data collection to monitoring result display.The advantages of Beidou technology in monitoring the slope deformation compared with the traditional slope deformation monitoring are analyzed.The accuracy test of the monitoring system is designed,and the relationship between the system accuracy and the positioning time is analyzed.The test results show that the accuracy of the horizontal direction of the monitoring system is about 2 mm when the positioning time is 24 h,which can fully meet the accuracy requirements of highway high slope deformation monitoring.The Beidou cloud monitoring system was applied to a high slope deformation monitoring project of Du’an Expressway in Guizhou,and the automatic monitoring of the slope deformation was realized.The monitoring results show that Beidou technology can be applied to the slope deformation monitoring,which is of great significance to improve the slope deformation monitoring capability. |
