The GPS reference station comprises a photovoltaic power supply system, a storage bin and a mechanical ejection device. The photovoltaic power supply system: through photovoltaic power supply for the GPS reference station, ensures long-term stable operation. The storage bin is used for storing the miniature GPS mobile stations. There are 50-100 miniature GPS mobile stations in the storage bin of each GPS reference station. The mechanical ejection device is used for throwing the miniature GPS mobile stations to the monitoring area.

[0046] Specifically, the mechanical ejection device includes an ejection structure, an ejection power source, and an ejection control module.

[0087] After the GPS reference station completes the deployment for the micro GPS mobile station, the position information sent by the micro GPS mobile station can be received.

[0088] Step 102, differentiating the position information and the signal of the GPS reference station to determine the deployment position of the micro GPS mobile station;

[0089] Then, based on the received position information, the signal of the GPS reference station is differentiated to determine the deployment position of the micro GPS mobile station.

[0090] Specifically, the step of differentiating the position information and the signal of the GPS reference station to determine the deployment position of the micro GPS mobile station includes: based on the signal of the GPS reference station, performing real-time dynamic differential calculation on the position information of each micro GPS mobile station to determine the absolute position of the micro GPS mobile station; and determining the absolute position of the micro GPS mobile station as the deployment position of the micro GPS mobile station.

[0091] For example, the reference station data can be collected, the reference station receives satellite signals and performs preliminary processing to generate reference data. Data transmission, the reference station transmits the reference data to all micro GPS mobile stations through a wireless communication module. Mobile station data reception and processing, the micro GPS mobile station receives the reference data and combines the satellite signals received by itself to perform differential processing.

Data synchronization and correction: the micro GPS mobile station transmits the positioning data to the reference station in real time through a wireless communication module, and the reference station performs data verification and error correction to ensure positioning accuracy.

[0092] Step 103, establishing a slope body displacement field according to the deployment position of the micro GPS mobile station;

Step 3: According to the stress distribution, apply the von Mises stress formula to calculate the von Mises stress of each point in the slope body. Step 4: Visualize the calculation results to generate a von Mises stress distribution map to assist in judging the stability of the slope body. Step 5: Compare and analyze the von Mises stress distribution of the two models.

[0101] For the original slope finite element model, the original slope model can be established based on the original geological data and the no-displacement condition, and the von Mises stress distribution is calculated.

[0102] For the real slope finite element model, the real slope model is established based on the real-time monitored displacement field data and the original geological data, and the von Mises stress distribution is calculated.
