In a long time before a landslide disaster occurs, a mountain generally has cracks in some areas due to the action of gravity, and the cracks gradually expand along with the passage of time. Therefore, the landslide condition can be predicted by measuring the width change condition of the cracks generated in certain areas of the mountain.

As an embodiment of the present invention, the data processing unit 301 is specifically configured to: and receiving and judging the magnitude relation between mountain body surface displacement data and a preset threshold value.
The early warning analysis decision unit 302 is specifically configured to: and when the judgment result of the data processing unit 301 is detected that the mountain surface displacement data is greater than the preset threshold value, outputting early warning information.
In the embodiment of the present invention, the preset threshold may be a mountain surface displacement warning threshold. The early warning information includes: voice, text or image information. For example, the warning information may be voice information of "XX mountain landslide level alert of XX site".
In a preferred embodiment of the present invention, a comparison result (taking a difference between the current crack width and a preset crack width as an example), a dangerous case level, and an early warning relationship mapping table of the early warning information may be pre-established, and the monitoring device 300 may output corresponding early warning information according to a corresponding relationship of the mapping table to warn the landslide degree of the current mountain. Wherein a is less than b.
TABLE 1
Generally, the larger the width of the mountain crack, the more severe the landslide condition, and conversely, the lighter the landslide condition. If the current mountain crack width reaches the preset early warning threshold value, early warning signals of different degrees can be output according to the early warning relation mapping table in the table 1, so that monitoring personnel can roughly deduce the dangerous case severity of the current mountain landslide according to the situation of the early warning information, and appropriate disaster prevention countermeasures are formulated according to the dangerous case severity, so that the early warning analysis efficiency is greatly improved, and the loss caused by disasters is favorably reduced as much as possible.
It can be understood that when the comparison result of the current mountain crack width and the preset mountain crack width is less than 0, no alarm information is output, that is, it indicates that no mountain landslide condition occurs in the current mountain.
