Description
Technical Field
The invention relates to the technical field of geological monitoring, in particular to a geological monitoring system based on GNSS and RTU linkage.
Background
GNSS refers to global navigation satellite system, and positioning of global navigation satellite system uses pseudoranges, ephemeris, and satellite transmission time of a set of satellites, and also needs to know clock error of a user. The global navigation satellite system is a space-based radio navigation positioning system that can provide users with all-weather 3-dimensional coordinates and velocity and time information at any location on the earth's surface or in near-earth space.
In the industrial application of the automatic monitoring of the geological disasters, the traditional automatic monitoring is to arrange different monitor sensors such as a GNSS, a rain gauge, a crack gauge, a flow meter, a stress gauge, a soil moisture meter and the like on geological disaster monitoring objects such as landslides, dangerous rocks, debris flow ditches and the like. Because the data processing and the working modes are different, the GNSS is generally independently monitored, other sensors are connected to a remote data acquisition terminal (RTU for short), the remote data acquisition terminal acquires and stores the monitoring data of the sensors and sends the monitoring data back to a data center through a 4G network and the like for data analysis, and the GNSS and the other sensors are used for monitoring geological disaster objects such as landslides, dangerous rocks, debris flow ditches and the like respectively. Most GNSS and remote data acquisition terminals on the market at present only have the functions of data acquisition, storage, reporting and the like, and each RTU and GNSS respectively monitor different geological disaster factors. Often can arrange many sets of RTU and GNSS on every geological disaster point, work independently respectively between GNSS and the RTU, and GNSS is responsible for monitoring the earth's surface displacement condition, and RTU connects other parameters such as different sensors responsible for monitoring crack, rainfall, flow, stress. For geological disasters such as landslide, monitoring factors such as ground surface displacement, rainfall, soil moisture content and cracks are mutually integrated and verified, for example, when the rainfall is increased and the soil moisture content is increased, landslide is caused to slide, and the ground surface is displaced. The earth surface displacement is the most important judgment index before landslide occurs. From the monitoring angle, when the rainfall is monitored to be increased, the change monitoring frequency of the soil moisture content and the monitoring frequency of the cracks can be encrypted in advance, and the purpose of starting emergency monitoring in advance is achieved, so that the change of the landslide body is reflected more accurately, early warning is achieved, and more time is strived for transferring personnel and property.
Then, the GNSS and the RTU are currently operated independently and are not related to each other. The real-time situation of the monitored object cannot be timely and accurately reflected by the monitoring data. A good monitoring effect cannot be achieved.
