Design and implementation of a double-layer landslide monitoring system based on GNSS-RTK technology

Abstract： Landslide and debris flow are the most frequent deformation geological disasters in our country. It is an important safety issue to establish a high-precision, real-time and stable monitoring system. Aiming at the problem of low efficiency of the traditional GNSS-RTK landslide monitoring system as the number of observation nodes increases and the alarm leakage caused by the simultaneous displacement of the base station and observation station, a double-layer landslide monitoring system based on GNSS-RTK technology is proposed. The double-layer landslide monitoring system based on GNSS-RTK technology is proposed. On the basis of the traditional landslide monitoring system, the new system adds a micro network observation system in some important node areas, which is improved from the previous "point" monitoring to the micro area "surface" monitoring, and realizes the deformation data collection based on GNSS-RTK technology and data transmission based on Lora and LTE technology. The test results show that the data transmission is reliable and efficient, and the measurement accuracy of the system can reach millimeter level, which can meet the requirements of landslide monitoring. The density of observation nodes and the length of baseline in the micro area of the observation station can be adjusted to meet the needs of different environments.
