The invention provides a landslide displacement settlement measuring system based on a Beidou automatic monitoring system. The landslide displacement settlement measuring system comprises a Beidou navigation system, a data processing system and an inspection and editing system, wherein the Beidou navigation system is used for obtaining ground line point cloud data; and the data processing system is used for processing the obtained point cloud data and performing data modeling and elevation interpolation according to the landslide displacement settlement class points in the point cloud data soas to obtain a landslide displacement settlement line. A Beidou satellite system is successfully applied to petroleum and gas industry for the first time; the real-time monitoring of production, storage and transportation process of oil gas pipelines, oil wells and natural oil gas wells in remote and wide-area spaces can be realized; the coverage area is large; the influence by territory conditionand the influence by weather can be avoided; and the problem of real-time two-way communication between production and management departments and various kinds of remote equipment in petroleum and gas industry is solved.
