3) When the offline of a certain monitoring acquisition point and/or the corresponding on-site data updating time length exceeds a preset signal loss risk threshold value, a communication base station state information acquisition request is initiated to a communication base station or a communication base station operator corresponding to the monitoring acquisition point;
in this embodiment, the communication base station status information acquisition request includes:
3-1), requesting off-line information of the base station, which is used for judging whether a monitoring blank is caused by a base station side factor;
3-2), requesting connection state information of other communication units with the distance from the monitoring acquisition point within a preset evaluation range;
the preset evaluation range may be determined according to a distance between the monitored collection point and the nearest population activity area in this embodiment, for example: the nearest village and road can be used as the evaluation range to determine the point positions;
the connection state information of the other communication units comprises information corresponding to normal or abnormal communication of the other communication units (such as resident mobile phones); the method is used for judging whether only the monitoring acquisition point is abnormal in communication or other communication units, if the other communication units are abnormal, suspected regional communication faults can be considered, and the fault probability of the monitoring acquisition point equipment is low; if other communication units are not abnormal, the fault probability of the monitoring acquisition point equipment is considered to be high;
4) Evaluating whether the monitoring acquisition point is abnormal or not according to the acquired communication base station state information, specifically:
when the feedback of the offline information of the request base station indicates that the communication base station is not offline, evaluating that the monitoring acquisition point is suspected to be abnormal, and carrying out the next step;

if other monitoring acquisition points of other monitoring acquisition points are offline and/or corresponding field data are updated normally, the monitoring acquisition points are estimated to be abnormal, and abnormal prompt information is sent to a specified terminal machine.
According to the method, when the meteorological information of the place where the monitoring and collecting point is located is utilized, whether communication abnormality is caused by the meteorological is not estimated directly according to landslide risk climate classification judgment rules, but other monitoring and collecting points close to the monitoring and collecting point are further utilized for verification, so that abnormality cause investigation assistance is provided more accurately, and warning can be sent out in time in severe weather.

When landslide appears on the slope body, even if the position of the monitoring collecting point is not collapsed, the traction net is pulled, and the base is pulled by the traction rope to enable the monitoring collecting point to move.
On the basis of the above, the supervision background is set as follows: analyzing the real-time position of the monitoring acquisition point based on the communication base station matched with the monitoring acquisition point; the base station positioning method is the prior art and will not be described in detail;
and if the difference between the real-time position and the pre-recorded anchoring position is larger than the error threshold value, a landslide check prompt is sent to the appointed terminal machine.
According to the above, on one hand, even if the anti-skid monitoring has no displacement detection facility, the anti-skid monitoring can be found when the landslide appears on the slope body; on the other hand, the device can be used as a safety, prevents monitoring blank from occurring after the field devices except the monitoring acquisition points are damaged, and can be used as a rescue triggering means when landslide occurs; and can be used for mutual verification with other field data, so that monitoring omission is reduced.
