Problems solved by technology

[0004] However, in the actual process of using GNSS technology for slope monitoring, because there are obstacles such as trees, mountains and buildings around the slope, GNSS signals are affected by various obstacles and produce multipath effects, so that the receiving module receives There is a large error in the data, which makes the deformation monitoring results of the slope inaccurate

Embodiment 1

[0022] Based on MIMO slope deformation monitoring and early warning system, such as figure 1 Shown: It includes a monitoring module, a multi-antenna receiving module, a processing module and an early warning module. The monitoring module is used to monitor the reference information of the reference station and the displacement information of the slope. The monitoring module is the existing GNSS slope deformation monitoring station. Specifically, The monitoring module includes a reference unit and a plurality of monitoring units. The reference unit detects the standard coordinates and acts as a reference information. The monitoring unit detects its coordinates in the deformation area as displacement information. The reference unit and the monitoring unit are GNSS monitoring stations. In the area, the monitoring units are evenly arranged on the deformation area. The monitoring units are equipped with a communicator and a controller. The communicator receives the displacement info...

Embodiment 2

[0031] The difference from the first embodiment is that each monitoring unit is provided with a pyroelectric infrared sensor, and the pyroelectric infrared sensor detects the human body signal and sends it to the controller. Interference identification, the processing module determines the number of changes of the displacement information of the same monitoring unit according to the human interference identification, and the processing module determines the human interference when the number of changes is greater than the preset threshold and adds a displacement label to the corresponding monitoring unit. The early warning module sends a warning signal, and the early warning module warns the displacement through the light. When the number of changes is less than the preset threshold, the processing module stops sending the warning signal, so that the displacement information of the monitoring unit can be found in time when someone enters the slope area.

Abstract

The invention relates to the technical field of correction of receiver components, in particular to a MIMO-based slope deformation monitoring and early warning system, comprising a monitoring module, a multi-antenna receiving module, a processing module and an early warning module. The monitoring module monitors reference information of reference stations and slopes. The multi-antenna receiving module receives the reference information and displacement information transmitted in multiple directions and sends them to the processing module. The processing module filters the received reference information and displacement information to suppress the multipath effect. The filtered reference information and displacement information are split and processed. The processing module calculates the deformation information of the slope according to the split and processed reference information and displacement information. The processing module sends an early warning signal to the early warning module according to the deformation information. Warning signal for slope deformation warning. The invention greatly reduces the interference of multipath effects, and improves the accuracy of subsequent analysis of slope deformation information based on data.

Description

technical field [0001] The invention relates to the technical field of correction of receiver components, in particular to a slope deformation monitoring and early warning system based on MIMO. Background technique [0002] The rapid urbanization process has accelerated the construction of roads, bridges and tunnels, resulting in more slopes. The slope area has a certain inclination angle and is reinforced by reinforced concrete structures. Even if the slope area is reinforced, the slope area is still prone to geological disasters such as landslides due to internal geological deformation. The deformation monitoring of the slope area is related to the geological Therefore, the deformation monitoring of the slope area is very important. [0003] The deformation monitoring of the slope area is usually carried out by using the Global Navigation Satellite System (Global Navigation Satellite System). , communication base station, data analysis subsystem, background monitoring su...
