Embodiment

[0057] Bring the data collected by the radar to the mining area into the early warning level function g=f(a,d,i),

[0058] The first set of data input: x=100, y=50, offx=10, offy=20

[0059] w=10, h=10, length=1000, i=100, t=163

[0060] calculation process:

[0061] The calculation is carried in the middle:

[0062] a=(x-offx) / w=(100-10) / 10=9

[0063] d=(y-offy) / h=(50-20) / 10=3

[0064] avg=(a / 2+d / 2) / (i+length)=(9 / 2+3 / 2) / (100+1000)=0.005454

[0065] Calculate the warning value:

[0066] No warning: (d×100+a=3×100+9=309)<(length=1000)

[0067] Yellow warning: s1=(30+avg×length)×2=(30+6 / 1100×1000)×2=70.908

[0068] Orange warning: s2=(60+avg×length)×2=(60+avg×length)×2=130.908

[0069]Red alert: s3=(90+avg×length)×2=(90+avg×length)×2=190.908

[0070] t≥s2, t

[0071] Output result: g=2

[0072] The warning level is level two, and the warning status is orange warning.

[0073] The second set of data input:

[0074] x=9...

Abstract

The invention discloses a registration and early warning algorithm based on a real aperture radar, and mainly relates to the technical field of early warning algorithms, and the early warning level ofa radar scanning area is determined by taking radar scanning data as a core and calculating width, height, deformation quantity and position offset. According to the invention, the mine early warninggrade can be mastered through operation, and the topographic change of the mine is objectively reflected, so that targeted measures can be taken; the radar monitoring station sends data to the serverat regular time, the early warning level of the area is mastered through operation, the topographic change of the current area is objectively reflected, the accuracy is high, and the method has greatsignificance in timely and effective taking of precautionary measures.

Description

technical field [0001] The invention relates to an early warning algorithm, in particular to a registration and early warning algorithm based on real aperture radar. Background technique [0002] Mine mining will produce landslides, and the deep part of the landslide is the goaf of coal mines. Coal mining causes rock and soil stress changes and deformation. This hazard is extremely dangerous. In order to prevent this kind of disaster, slope aperture radar is used to analyze mining area data Collect and collect data for early warning. After the on-site radar collects the data, the monitoring data is uploaded to the system server through the interface call. After receiving the data, the server performs data storage and data analysis. Query, at this time, an early warning algorithm is needed to display the registration results of the aperture radar on the client, and at the same time, perform curve analysis on the selected data through point selection or area selection to calcu...
