Abstract

The invention discloses a rapid and high-precision GNSS landslide monitoring method, device and system. The method comprises the following steps: obtaining initial three-dimensional coordinates of a GNSS base station and a GNSS monitoring station during installation through an ad hoc network as adjustment values; obtaining real-time three-dimensional coordinates of each GNSS monitoring station in the GNSS base station and the GNSS monitoring stations at the same time T through an ad hoc network; according to the real-time three-dimensional coordinate and the initial three-dimensional coordinate of the GNSS base station, determining a correction value of the GNSS base station, and taking the correction value as a corresponding correction value of all the GNSS monitoring stations at the time T to obtain a change value of each GNSS monitoring station in the three-dimensional direction; and when the change value of any direction in the three-dimensional directions is greater than a preset threshold value of the direction, generating an alarm signal. By adopting the method, landslide monitoring can be realized without a 4G network, satellite data can be prevented from being influenced by environmental factors such as ionosphere disturbance and troposphere delay, and the precision of landslide data monitoring without the 4G network is improved.

Description

technical field [0001] The invention belongs to the technical field of landslide monitoring, and in particular relates to a fast and high-precision GNSS landslide monitoring method, device and system. Background technique [0002] GNSS (Global Satellite Positioning System) has been introduced into the monitoring of geological disasters as a high-tech in recent years. It has all-weather, fast positioning, high precision, automation, and measuring stations. The measuring station and the reference station do not need to be in sight. Therefore, it is also widely used in the monitoring of landslide deformation of geological disasters, bridges, reservoir dams, and dangerous buildings. For ground users, the influence of various complex environments needs to be considered comprehensively during the process from the space satellite transmitting signals to the user receiving signals. When the signal passes through the atmosphere, it will be affected by environmental factors such as io...
