GNSS ground disaster deformation monitoring system and method based on virtual reference station

Abstract

The invention belongs to the technical field of ground disaster deformation monitoring, and discloses a GNSS ground disaster deformation monitoring system and method based on a virtual reference station. GNSS observation information and sensor observation information are collected through a monitoring station, and the GNSS observation information and the sensor observation information are transmitted to a data center in real time; the data center processes the sensor observation information to obtain a short-term displacement calculation result; the data center generates the virtual referencestation by using a satellite tracking station, and the GNSS observation information is processed by using a virtual reference station technology to obtain a GNSS calculation result; and the data center combines the short-term displacement calculation result and the GNSS calculation result to obtain monitoring information. According to the GNSS ground disaster deformation monitoring system and method, the problem of the poor monitoring effect of GNSS ground disaster deformation monitoring under extreme conditions in the prior art is solved, and the technical effects of eliminating false alarmsand improving the monitoring precision are achieved.

Description

technical field [0001] The invention relates to the technical field of geological disaster deformation monitoring, in particular to a GNSS ground disaster deformation monitoring system and method based on a virtual reference station. Background technique [0002] Line facilities such as roads, railways, and bridges require high-precision and high-reliability measurement work to maintain daily monitoring and maintenance during the construction phase and subsequent operation phase. Especially for parts such as dangerous deformation bodies and soft foundations, landslides will cause huge loss of life and property. In order to ensure the safety of operations and operations, GNSS technology is currently used as a means of monitoring disaster deformation, and it is also combined with other means to complement each other. However, complex technologies and different manufacturers make the fusion system have problems such as inconsistent benchmarks, communication problems, and poor ...
